21 May '18

From: Srinivas Kandagatla <srinivas.kandagatla(a)linaro.org> This patchset aims to provide a basic version of QCOM DSP based audio support which is available in downstream andriod kernels. This patchset support audio playback on HDMI-RX, MI2S, SLIMBus and will add support to other features as we move on. QDSP has both static and dynamic modules. static modules like AFE (Audio FrontEnd), ADM (Audio Device Manager), ASM(Audio Stream Manager) and CORE to provide this audio services. All these services use APR (Asynchronous Packet Router) protocol via smd/glink transport to communicate with Application processor. More details on each module is availble in there respective patch. This patchset is tested on DB820c, with HDMI audio playback, MI2S on DB410c on top of mainline, Also tested SLIMBus analog audio using wcd9355 with an additional patches.

[alsa-devel] [PATCH v8 00/24] ASoC: qcom: Add support to QDSP based Audio
by Srinivas Kandagatla 21 May '18

21 May '18

Thankyou everyone for providing feedback and testing v7 patchset. This patchset aims to provide a basic version of QCOM DSP based audio support which is available in downstream andriod kernels. This patchset support audio playback on HDMI-RX, MI2S, SLIMBus and will add support to other features as we move on. QDSP has both static and dynamic modules. static modules like AFE (Audio FrontEnd), ADM (Audio Device Manager), ASM(Audio Stream Manager) and CORE to provide this audio services. All these services use APR (Asynchronous Packet Router) protocol via smd/glink transport to communicate with Application processor. More details on each module is availble in there respective patch. This patchset is tested on DB820c, with HDMI audio playback, MI2S on DB410c on top of mainline, Also tested SLIMBus analog audio using wcd9355 with an additional patches. Patches are also tested on SDM845 by Rohit.

[alsa-devel] [PATCH] ALSA: dice: add stream format parameters for TC Electronic Digital Konnekt x32
by Takashi Sakamoto 21 May '18

21 May '18

TC Electronic Digital Konnekt x32 is an application of WaveFront DiceII STD and doesn't support TCAT extended application protocol. For such devices, ALSA dice driver needs to have hard-coded parameters for stream formats. This commit adds stream format parameters for this model. Unfortunately, at sampling transmission frequencies of 88.2/96.0kHz, I confirmed that current ALSA dice driver doesn't drive the device appropriately due to detecting packet discontinuities. $ journalctl kernel: snd_dice fw1.0: Detect discontinuity of CIP: 90 80 At the frequencies, the device transfers 16 data blocks per packet and 16 data channels per data block, as a result one packet includes 1032 bytes if it's not NODATA. However, as long as I checked, the device often postpone packet transmission and continue with truncated payload than metadata in isochronous packet header. Below is a sample of sequence I got. sec cycle bytes CIP1 CIP2 37 3314 1032 0x01100090 0x900449E2 37 3315 8 0x011000A0 0x9004FFFF 37 3316 1032 0x011000A0 0x900461E2 37 3317 1032 0x011000B0 0x900475E2 37 3318 1032 0x011000C0 0x900489E2 37 3319 8 0x011000D0 0x9004FFFF 37 3320 1032 0x011000D0 0x9004A1E2 37 3321 1032 0x011000E0 0x9004B5E2 37 3322 1032 0x011000F0 0x9004C9E2 37 3323 8 0x01100000 0x9004FFFF 37 3324 1032 0x01100000 0x9004E1E2 37 3325 1032 0x01100010 0x9004F5E2 37 3326 1032 0x01100020 0x900409E2 37 3327 8 0x01100030 0x9004FFFF 37 3328 1032 0x01100030 0x900421E2 37 3329 1032 0x01100040 0x900435E2 37 3330 (skip) 37 3331 (skip) 37 3332 (skip) 37 3333 (skip) 37 3334 (skip) 37 3335 (skip) 37 3336 (skip) 37 3337 (skip) 37 3338 (skip) 37 3339 (skip) 37 3340 (skip) 37 3341 (skip) 37 3342 (skip) 37 3343 (skip) 37 3344 (skip) 37 3345 (skip) 37 3346 (skip) 37 3347 (skip) 37 3348 (skip) 37 3349 (skip) 37 3350 (skip) 37 3351 (skip) 37 3352 (skip) 37 3353 (skip) 37 3354 (skip) 37 3355 (skip) 37 3356 (skip) 37 3357 (skip) 37 3358 (skip) 37 3359 (skip) 37 3360 (skip) 37 3361 (skip) 37 3362 (skip) 37 3363 (skip) 37 3364 (skip) 37 3365 (skip) 37 3366 (skip) 37 3367 1032 0x01100050 0x900461E1 37 3368 1032 0x01100060 0x900475E1 37 3369 1032 0x01100070 0x9004A1E1 37 3370 1032 0x01100080 0x9004A1E1 but content of payload is truncated. 37 3371 (skip) 37 3371 1032 0x01100080 0x9004B5E0 detect discontinuity 37 3372 1032 0x01100090 0x9004C9E0 37 3373 1032 0x011000A0 0x9004E1E0 37 3374 1032 0x011000B0 0x9004F5E0 37 3375 1032 0x011000C0 0x900409E0 37 3376 1032 0x011000D0 0x900421E0 37 3377 1032 0x011000E0 0x900435E0 37 3378 1032 0x011000F0 0x900449DF 37 3379 8 0x01100000 0x9004FFFF 37 3380 1032 0x01100000 0x900461DF 37 3381 1032 0x01100010 0x900475DF 37 3382 1032 0x01100020 0x900489DF 37 3383 8 0x01100030 0x9004FFFF 37 3384 1032 0x01100030 0x9004A1DF 37 3385 1032 0x01100040 0x9004B5DF 37 3386 1032 0x01100050 0x9004C9DF 37 3387 8 0x01100060 0x9004FFFF I cannot confirm this quirks with Windows driver. ALSA dice driver has a cause if assumed differences between these two drivers are ways of timestampling to RX packets from the drivers to the device. I've already reported timestamping quirk of Dice-based devices and this might bring this issue. [alsa-devel] Dice packet sequence quirk and ALSA firewire stack in Linux 4.6 http://mailman.alsa-project.org/pipermail/alsa-devel/2016-May/107715.html Well, nevertheless, I enable ALSA dice driver to work at the frequencies.

[alsa-devel] [PATCH 1/2] conf/ucm: bytcr-rt5640: Add generic bytcr-rt5640 UCM profile
by Hans de Goede 19 May '18

19 May '18

This commit adds the generic UCM profile for bytcr-rt5640 boards from: https://github.com/plbossart/UCM, plus the fixes from this pull-req: https://github.com/plbossart/UCM/pull/31 The profile has been split up into separate per input / output files to allow for creation of long-name profiles with the specific input / output combinations found on a board without needing to copy and paste things. Note this profile exports all inputs and both stereo/mono speaker setups even though a typical device will not use all. Ideally a long-name based device specific profile made up of the various parts should be used instead.

[alsa-devel] [PATCH 00/19] ASoC: rt5640: Add jack-detect and button-press support
by Hans de Goede 18 May '18

18 May '18

Hi All, This series has been long in the making, but it is finally ready now. This series adds jack-detect support for rt5640 using devices. This is modelled after the recent rt5651 codec- and bytcr-rt5651 machine- driver jack-detect changes (which were actually based on a WIP version of this series). As discussed on the list already unfortunately there are no really good defaults which work everywhere, so patch 18 adds quirks for 10 devices, I've decided to do this in one go rather then split this into 10 patches. Patch 19 makes the bytcr-rt5640 set a longname based on the speaker and input-map quirks, so that userspace can pick a correct UCM profile based on the longname with working jack-detect based input / output switching. I've matching patches adding UCM profiles for this to alsa-lib here: https://github.com/jwrdegoede/alsa-lib/commits/master I'm waiting with submitting those upstream until patch 19 is accepted for merging. Regards, Hans

[alsa-devel] sound: latency and synchronization measurements
by Muni Sekhar 18 May '18

18 May '18

[ Please keep me in CC as I'm not subscribed to the list] Hi All, I am trying to characterize the audio synchronization between two systems. There is a mechanism to route audio between two systems, we run ‘aplay’ at one system and ‘arecord’ in other system. We need to measure the time difference when audio sample is out at one port and arriving at another port in different system. I plan to add printk’s in “struct snd_pcm_ops” call backs, but does these call backs tells when it received first and last audio frames\samples? Or else please suggest any other best method. -- Thanks, Sekhar

[alsa-devel] [PATCH] ALSA: emu10k1: Rate-limit error messages about page errors

The error messages at sanity checks of memory pages tend to repeat too many times once when it hits, and without the rate limit, it may flood and become unreadable.

[alsa-devel] Applied "ASoC: ssm2305: Add amplifier driver" to the asoc tree
by Mark Brown 17 May '18

17 May '18

The patch ASoC: ssm2305: Add amplifier driver has been applied to the asoc tree at https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted. You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail. Thanks, Mark >From 74f24d8728ef12276d58e3d73283cc1d76db7507 Mon Sep 17 00:00:00 2001 From: Marco Felsch <m.felsch(a)pengutronix.de> Date: Thu, 17 May 2018 15:55:18 +0200 Subject: [PATCH] ASoC: ssm2305: Add amplifier driver The ssm2305 is a simple Class-D audio amplifier. A application can turn on/off the device by a gpio. It's also possible to hardwire the shutdown pin. Tested on a i.MX6 based custom board.

[alsa-devel] [PATCH v3 00/10] ASoC: rt5640: Add jack-detect and button-press support
by Hans de Goede 17 May '18

17 May '18

Hi Mark, et. al., Here is v3 of the remaining patches from my rt5640 jack-detect series. This time this is really based on your sound/for-next branch, so this should apply cleanly now. As mentioned with v2 I've also added a quirk for one more device to the: "ASoC: Intel: bytcr_rt5640: Add quirks for various devices" patch. Other then that there are no changes. Regards, Hans

[alsa-devel] [PATCH 0/1] Handling of serializers
by Vishal Thanki 17 May '18

17 May '18

On a custom AM33xx based platform, we use 4 channels for audio output (2 * Left/Right) by making use of two TX serializers. The audio input path only uses 2 channels, hence one RX serializer. If the recording is started before the playback, the playback cannot make use of all 4 channels because of the imposed max number of channels by recording. And if playback is started before recording, the hw_params set during recording stream would disable an active TX serializer which causes audio distortion. I have tried to fix this unwanted behavior in following patch. Please comment if this should be done differently.

[alsa-devel] [PATCH 1/2] ALSA: timer: Simplify timer hw resolution calls
by Takashi Iwai 17 May '18

17 May '18

There multiple open-codes to get the hardware timer resolution. Make a local helper function snd_timer_hw_resolution() and call it from all relevant places.

[alsa-devel] Is add uevent of controlC still a reliable synchronization point?
by Tzung-Bi Shih 17 May '18

17 May '18

Hi, We found an assumption in 78-sound-cards.rules and commit 289ca025ee1d78223e3368801fc2b984e5efbfc7 are conflict. The control device will not be the last one to register. The assumption in 78-sound-card.rules: > The control device node creation can be used as synchronization point. All other devices that belong to a card are created in the kernel before it.

As a result, SNDRV_DEV_CONTROL devices will be registered before most other devices. We are writing to ask: Is add uevent of controlC still a reliable signal for indicating everything is ready for a sound card? Or is there now a better way to do so?

[alsa-devel] [PATCH v3] ASoC: da7219: read fmw property to get mclk for non-dts systems
by Akshu Agrawal 17 May '18

17 May '18

Non-dts based systems can use ACPI DSDT to pass on the mclk to da7219. This enables da7219 mclk to be linked to system clock. Enable/Disable of the mclk is already handled in the codec so platform drivers don't have to explicitly do handling of mclk.

[alsa-devel] Aplay Fails When Reading From stdin
by Jay Foster 16 May '18

16 May '18

I recently updated may alsa from 1.1.4.1 to 1.1.6. I now noticed that aplay does not work properly (the same as 1.1.4.1) when reading the sound file data from stdin. This might have something to do with the recent change with reading the sound file header. With the previous version of aplay, aplay would report: Playing WAVE 'stdin' : Signed 16 bit Little Endian, Rate 22050 Hz, Mono With 1.1.6, aplay reports: Playing raw data 'stdin' : Unsigned 8 bit, Rate 8000 Hz, Mono This results in static/noise output. If I explicitly add the '-f S16_LE -r 22050' options to aplay, then it does play correctly. Is this a known bug and is there a fix? Jay

[alsa-devel] [alsa-lib][PATCH 0/6] control: optimization for position offset macro of TLV data
by Takashi Sakamoto 15 May '18

15 May '18

Hi, In development period for Linux v4.18, a series of SNDRV_CTL_TLVO_XXX macro was introduced to kernel stuffs for position offset of TLV data. This patchset backports the macros to this library as well as adds code optimization with them. Takashi Sakamoto (6): control: add a series of macro for offset of several types of TLV control: use position offset macro of TLV data hcontrol: use position offset macro of TLV data pcm: hw: use position offset macro of TLV data pcm: softvol: use position offset macro of TLV data test: use position offset macro of TLV data include/sound/tlv.h | 16 ++++++++++ src/control/control.c | 12 ++++---- src/control/control_hw.c | 6 ++-- src/control/control_local.h | 1 + src/control/hcontrol.c | 4 +-- src/control/tlv.c | 72 ++++++++++++++++++++++++--------------------- src/pcm/pcm_hw.c | 10 ++++--- src/pcm/pcm_softvol.c | 11 ++++--- test/user-ctl-element-set.c | 2 +- 9 files changed, 83 insertions(+), 51 deletions(-) -- 2.14.1

[alsa-devel] [PATCH V3] ASoC: amd: modified dma pointer callback implementation
by Vijendar Mukunda 15 May '18

15 May '18

Modified dma pointer callback implementation. hw ptr calculated based on System Memory to ACP SRAM dma channel transfer count in case of playback. In case of capture, hw ptr calculated based on dma transfer count for ACP SRAM to System Memory Dma channel. Added IOC Bit for Sysmem to ACP Dma channel for both controller instances. Invoked snd_pcm_period_elapsed() call when IOC is reported for System memory to ACP SRAM DMA channel. Signed-off-by: Vijendar Mukunda <Vijendar.Mukunda(a)amd.com> Signed-off-by: Akshu Agrawal <akshu.agrawal(a)amd.com> --- v1->v2: removed hard coded values in acp dma pointer callback declared dma varaibles in rtd structure. v2->v3: modified code to invoke snd_pcm_period_elapsed() call when IOC reported for System Memory to ACP SRAM dma channel.

Hi, Changes since v1: - Changed the MODULE_LICENSE from "GPL" to "GPL v2" to match the SPDX line. Since the sdma-pcm can be built as module it must have MODULE_LICENSE defined, whcih I have missed: After merging the sound-asoc tree, today's linux-next build (x86_64 allmodconfig) produced this warning: WARNING: modpost: missing MODULE_LICENSE() in sound/soc/omap/snd-soc-sdma.o see include/linux/module.h for more information WARNING: modpost: missing MODULE_LICENSE() in sound/soc/omap/snd-soc-sdma.o see include/linux/module.h for more information The first patch also going to fix runtime issue with module loading: snd_soc_sdma: Unknown symbol devm_kmalloc (err 0) snd_soc_sdma: Unknown symbol omap_dma_filter_fn (err 0) snd_soc_sdma: Unknown symbol snd_dmaengine_pcm_prepare_slave_config (err 0) snd_soc_sdma: Unknown symbol devm_snd_dmaengine_pcm_register (err 0) As these symbols are EXPORT_SYMBOL_GPL()... Introduced by commit dde637f2daf1 ("ASoC: omap: Introduce the generic_dmaengine_pcm based sdma-pcm") The second patch is kust a small adjustement for the include files.

[alsa-devel] [PATCH 0/4] ALSA: usb: UAC3 new features.
by Jorge Sanjuan 15 May '18

15 May '18

Now that the UAC3 patch [1] has made it to linux-next I have some extra features to make a UAC3 device fully work in Linux. Including Jack insertion control that I have put on top of this other patch [2] for UAC2. Also adding support for the UAC3 Mixer Unit which is most likely to appear in most headset type devices. UAC3 devices also require to have a Basic Audio Device (BADD) in a separate config for which both Ruslan Bilovol and myself have submited different approaches[3][4] but I don't know what the final merge will be. Once there is official support for BADD, we'll need to test it with an actual UAC3 device to confirm it all wokrs. All this features are tested with an actual UAC3 device that is still in development. For this patch series, only the legacy config (#1. UAC1/UAC2) and the UAC3 config have been tested. The BADD config is only tested using and updated verison of [4].

[alsa-devel] [PATCH v14 0/8] ASoC: sun4i-codec: Add Line-In, FM-In, Mic 2, Capture Source, Differential Line-In
by Danny Milosavljevic 14 May '18

14 May '18

This patchset adds some mixer controls to sun4i-codec for the Allwinner A10 and the Allwinner A20. It also adds a mux for the capture source and the PGA for the MIC2 preamp. Where possible, it uses SOC_DAPM_DOUBLE in order to cut down on the number of distinct controls in alsamixer. v14 changes compared to v13 are: - Merged some of the patches together if it made sense to test them together. - Use snd_soc_component_driver. - Moved SUN4I_CODEC_DAC_ACTL_LFMS, SUN4I_CODEC_DAC_ACTL_RFMS to the correct patch in the series. - Kept "Left Mixer Left DAC Playback Switch", "Right Mixer Left DAC Playback Switch" and "Right Mixer Right DAC Playback Switch" unchanged compared to the released version - for backward compatibility. v13 changes compared to v12 are: - Added my "Signed-off-by". - Clarified some commit message text. v12 changes compared to v11 are: - Split up patchset in another way. - Renamed "Mic1 Capture Volume" to "Mic1 Boost Volume". - Renamed "Mic2 Capture Volume" to "Mic2 Boost Volume". - Renamed "Line Capture Volume" to "Line Boost Volume". - Renamed "Differential Line Capture Switch" to "Differential Line Source". v11 changes compared to v10 are: - Split up patchset. - Fixed typo in Differential Line Capture Switch. - Renamed "Non-Differential" value to "Stereo". - Removed duplicate PA Volume mixer control. v10 changes compared to v9 are: - Use SOC_DAPM_DOUBLE where possible and it makes sense in order to cut down on the number of controls. v9 changes compared to v8 are: - added Line Differential Capture Switch. - split Capture Source into Left Capture Select, Right Capture Select. - added Line Capture Volume. - rename "sun4i_codec_widgets" to "sun4i_codec_controls" for consistency with the struct field it's used in. - rename "Line-In" to "Line". - rename "Power Amplifier Playback Volume" to "Headphone Playback Volume". v8 changes compared to v7 are: - fixed the routes for line and mic capturing. v7 changes compared to v6 are: - preparation for different A20, A10 controls is now in an extra patch. - all register definitions are now at the top. - sun7i-specific things (A20-specific things) are now less grouped-together. - rename "Power Amplifier Volume" to "Power Amplifier Playback Volume". v6 changes compared to v5 are: - Mic preamplifier special cases for A20 and A10 now are now not icky: There are two different _widget arrays and the probe() function now selects the right one to pass to snd_soc_register_codec() unmodified. - sun7i-specific things (A20-specific things) are now grouped together. v5 changes compared to v4 are: - Mic preamplifier controls have more common names now. - Mic preamplifier scale has a 0 dB entry as well now, as documented in the A20 user manual. - Mic preamplifier has special cases for A20 and A10 now. - Gain controls have "Gain" in the name now. v4 changes compared to v3 are: - names of the input are not uppercase anymore. - bit index constants are now named as in the A20 user manual v1.4. - added Mic1-In, Mac2-In. - added Mic1 and Mic2 Pre-Amplifiers. v3 changes compared to v2 are: - added DAPM routes. v2 changes compared to v1 are: - moved Line-In and FM-In playback switches to their respective sun4i_codec_*_mixer_controls. v1 changes: - added linein, fmin output volumes and switches.

[alsa-devel] sound: aplay\arecord audio frame flow
by Muni Sekhar 14 May '18

14 May '18

[ Please keep me in CC as I'm not subscribed to the list] Hi All, Is there anyway in the kernel sound subsystem to know when the application calls ‘aplay’ and anything starts playing? Also for arecord\aplay, Is there any way from kernel's point of view to know when it receives for example the first and last audio frames? -- Thanks, Sekhar

[alsa-devel] [PATCH V2] ASoC: amd: modified dma pointer callback implementation
by Vijendar Mukunda 14 May '18

14 May '18

Modified dma pointer callback implementation. hw ptr calculated based on System Memory to ACP SRAM dma channel transfer count in case of playback. Increased min period size for playback to 4096 to avoid underruns. In case of capture, hw ptr calculated based on dma transfer count for ACP SRAM to System Memory Dma channel.

[alsa-devel] [PATCH v4] ALSA: core api: define offsets for TLV items
by Ranjani Sridharan 13 May '18

13 May '18

Currently, there are no pre-defined accessors for the elements in topology TLV data. In the absence of such offsets, the tlv data will have to be decoded using hardwired offset numbers 0-N depending on the type of TLV. This patch defines accessor offsets for the type, length, min and mute/step items in TLV data for DB_SCALE type tlv's. These will be used by drivers to decode the TLV data while loading topology thereby improving code readability. The type and len offsets are common for all TLV types. The min and step/mute offsets are specific to DB_SCALE tlv type.

[alsa-devel] [PATCH v5 00/13] ALSA: hda/ca0132: Patch Series for Recon3Di and Sound Blaster Z Support
by Connor McAdams 13 May '18

13 May '18

This patchset adds support for the Sound Blaster Z and the Recon3Di. In order to figure out how to get these cards to work, I made a program called QemuHDADump[1], which uses the trace function of qemu to see interactions with the memory mapped pci BAR space of the card being used in the virtual machine. With this, I obtain the CORB buffer location to get the command verbs, and then dump them each time the buffer rolls over. This program may be useful for fixing other HDA related driver issues where there is no documentation for the device. So far, I have been able to get all features supported on the Sound Blaster Z and the Recon3Di. All output and input effects work, all inputs and outputs work, and just about anything else I can think of. I have also added new controls in order to select the new inputs and outputs, as well as controls to change the effect levels and presets. I have also added the ability to use firmware taken from the Windows drivers of both the Sound Blaster Z and Recon3Di. I am trying to get into contact with Creative to get permission to redistribute these along with the current file included with the Chromebook, but they have not been very responsive. Luckily, the cards work with the Chromebook firmware just fine, although I believe there has to be a reason they have different firmware in Windows. I will not link to the firmwares here, but if you look up my thread on Creative Labs forums, you will find the link to download the firmwares there. I am willing to help get the other non-working cards such as the ZxR and the newer AE-5 working too, but I will need someone willing to run QemuHDADump in a virtual machine in order to get the commands. So, in summary: -This patchset makes the cards work better than they did before (they really didn't work before) -This patchset leaves the original chromebook related stuff alone. Thanks.

[alsa-devel] [PATCH] ALSA: control: fix a redundant-copy issue
by Wenwen Wang 13 May '18

13 May '18

In snd_ctl_elem_add_compat(), the fields of the struct 'data' need to be copied from the corresponding fields of the struct 'data32' in userspace. This is achieved by invoking copy_from_user() and get_user() functions. The problem here is that the 'type' field is copied twice. One is by copy_from_user() and one is by get_user(). Given that the 'type' field is not used between the two copies, the second copy is *completely* redundant and should be removed for better performance and cleanup. Also, these two copies can cause inconsistent data: as the struct 'data32' resides in userspace and a malicious userspace process can race to change the 'type' field between the two copies to cause inconsistent data. Depending on how the data is used in the future, such an inconsistency may cause potential security risks. For above reasons, we should take out the second copy.

[alsa-devel] [PATCH v2 0/7] USB Audio Device Class 3.0 BADD profiles support
by Ruslan Bilovol 13 May '18

13 May '18

This patchset adds BADD profiles support from the USB Audio Device Class 3.0 spec [1]. BADD profile support is defined as mandatory feature of UAC3-compliant device, it should be implemented as a separate USB configuration. Notable issue with BADD configuration is that it misses class-specific descriptors (and it's mandatory as per spec), so host should guess them from BADD profile number and parameters of endpoints (type, number of endpoints and max packet size) This patchset adds support of all known/existing BADD profiles from the UAC3 specification. First 5 patches are refactoring and improvements, and last 2 patches actually implement UAC3 BADD profiles support. It's an alternative implementation comparing to [2], and doesn't build usb descriptors on the host but instead initializes alsa-usb structures with known parameters, so we don't need to keep whole class-specific descriptors in the driver since we anyway need to have BADD-specific logic. I've picked one Jorge's UAC1 patch-improvement and updated it to v4.17 wich contais recently introduced header's sanity checks. Remaining part is to add interrupt endpoint support so we will be able to detect jack insertion in the Headset Adapter profile. This has been tested on ARM and x86-64 machines with custom UAC3 gadget which I'll post later to linux-usb Comments and testing are welcome. v2: - split refactoring patch to more atomic and bisectable changes as suggested by Takashi - renamed "Side Tone"->"Sidetone" as suggested by Andrew - revorked main BADD patch to have table lookup for checking BADD channels validity and to reduce identation as suggested by Takashi - also removed code duplication in BADD patch by reusing common part of build_feature_ctl() func v1: http://mailman.alsa-project.org/pipermail/alsa-devel/2018-April/134412.html [1] http://www.usb.org/developers/docs/devclass_docs/USB_Audio_v3.0.zip [2] https://www.spinics.net/lists/alsa-devel/msg71614.html Jorge Sanjuan (1): ALSA: usb: Only get AudioControl header for UAC1 class.

[alsa-devel] What is the meaning of #sound-dai-cells in a device tree?
by sdaau 11 May '18

11 May '18

Hi all, Apologies if this isn't the right forum (my thinking was, is that it is related to sound, and thus ALSA, more) - however, if it isn't, please let me know where I could forward this query (maybe devicetree mailing list ?) I have tried, but I really cannot find any documentation where I can read about, what does conceptually #sound-dai-cells in a device tree mean. Most I've found so far, is: linux_git$ grep -r 'sound-dai-cells' --exclude-dir='.git' arch/arm/boot/dts/sun7i-a20-cubietruck.dts: #sound-dai-cells = <0>; ... arch/arm/boot/dts/r8a7790.dtsi: * #sound-dai-cells is required arch/arm/boot/dts/r8a7790.dtsi: * Single DAI : #sound-dai-cells = <0>; <&rcar_sound>; arch/arm/boot/dts/r8a7790.dtsi: * Multi DAI : #sound-dai-cells = <1>; <&rcar_sound N>; ... Documentation/devicetree/bindings/sound/hisilicon,hi6210-i2s.txt:- #sound-dai-cells: Should be set to 1 (for multi-dai) ... As far as I can tell: * if it is 1, then you can refer to "ports" (?) of a soundcard node, i.e. <&rcar_sound N>; * if it is 0, then you cannot refer to "ports", and you can only refer to <&rcar_sound> Also, it seems to appear only in these kernel source files: drivers/misc/atmel-ssc.c: if (!of_property_read_bool(np, "#sound-dai-cells")) drivers/misc/atmel-ssc.c: if (of_property_read_bool(ssc->pdev->dev.of_node, "#sound-dai-cells")) ... sound/soc/generic/simple-card.c:#define CELL "#sound-dai-cells" ... sound/soc/generic/simple-scu-card.c:#define CELL "#sound-dai-cells" ... sound/soc/soc-core.c: "#sound-dai-cells", 0, &args); sound/soc/soc-core.c: "#sound-dai-cells"); sound/soc/soc-core.c: "#sound-dai-cells", ... so, I guess, it only has meaning in what would be nodes under `target = <&sound>;` in a device tree - is that correct? But then - what is sound-dai-cells actually describing? Number of entries in `static struct snd_soc_dai_driver` of a (codec?) driver, if it is defined as an array? Or a number of DAI links? Could anyone offer a more proper conceptual description of what #sound-dai-cells is supposed to describe? Many thanks in advance for any pointers, s.

[alsa-devel] [PATCH] ASoC: davinci-mcasp: Only disable inactive serializer
by Vishal Thanki 11 May '18

11 May '18

As a side effect of the following commit, the active TX serializer may get disabled which may result in distorted audio output. ASoC: davinci-mcasp: Add support for multichannel playback (2952b27e2e463b28d5c0f04000f96b968137ca42) For example, if a 4 channel I2S playback with two TX serializers is activated. Later on, if a recording of 2 channels, with only 1 RX serializer is started, which will also disable one of the TX serializer because max_active_serializers is only calculated for RX (recording) stream. This patch fixes this issue.

[alsa-devel] [PATCH v7 00/24] ASoC: qcom: Add support to QDSP based Audio
by Srinivas Kandagatla 11 May '18

11 May '18

Thankyou everyone for providing feedback and testing v6 patchset. This patchset aims to provide a basic version of QCOM DSP based audio support which is available in downstream andriod kernels. This patchset support audio playback on HDMI-RX, MI2S, SLIMBus and will add support to other features as we move on. QDSP has both static and dynamic modules. static modules like AFE (Audio FrontEnd), ADM (Audio Device Manager), ASM(Audio Stream Manager) and CORE to provide this audio services. All these services use APR (Asynchronous Packet Router) protocol via smd/glink transport to communicate with Application processor. More details on each module is availble in there respective patch. This patchset is tested on DB820c, with HDMI audio playback, MI2S on DB410c on top of mainline, Also tested SLIMBus analog audio using wcd9355 with an additional patches. Patches are also tested on SDM845 by Rohit. Here is my test branch incase someone want to try these patches https://git.linaro.org/people/srinivas.kandagatla/linux.git/log/?h=v4.17-qd… Here is block diagram to give a quick overview of the components +---------+ +---------+ +---------+ | q6asm | |q6routing| | q6afe | | dais | <------> | mixers | <-----> | dais | +---------+ +---------+ +---------+ ^ ^ ^ | | | | +------------------+----------------+ | | | | | | v v v v v +---------+ +---------+ +---------+ | q6ASM | | q6ADM | | q6AFE | +---------+ +---------+ +---------+ ^ ^ ^ ^ | | | CPU Side | ------+---------------------+-------------------+-------- | | | | |APR(smd/glink) | | | | | +------------------+----------------+ | | | | | | +-----+--+-----------------------------------+--+------- | | | | | QDSP Side | v v v v v v +---------+ +---------+ +---------+ | ASM | <------> | ADM | <-----> | AFE | +---------+ +---------+ +---------+ ^ | +-------------------+ | ---------------------------+-------------------------- | Audio I/O | v v +--------------------------------------------------+ | Audio devices | | CODEC | HDMI-TX | PCM | SLIMBUS | I2S |MI2S |...| | | +--------------------------------------------------+ Changes since v6 (https://lkml.org/lkml/2018/4/26/264) -

Thanks, Mark >From 8e7a1f1f177fef28cbd5edc663044b8946d08ab2 Mon Sep 17 00:00:00 2001 From: Hans de Goede <hdegoede(a)redhat.com> Date: Tue, 8 May 2018 17:35:46 +0200 Subject: [PATCH] ASoC: rt5640: Remove is_sys_clk_from_pll, it has ordering issues is_sys_clk_from_pll() is used as a snd_soc_dapm_route.connected callback, checking RT5640_GBL_CLK to determine if the sys-clk is PLL1 and thus the PWR_PLL bit in reg PWR_ANLG2 must be set. RT5640_GBL_CLK is changed by rt5640_set_dai_sysclk(), which gets called by the pre_pmu / post_pmd functions of the "Platform Clock" dapm-supply. This creates an ordering issue, during a dapm transition first all connected() callbacks are called to build a list of supplies to enable and then the complete list is walked to enable the supplies. Since the connected() check happens before enabling any supplies, is_sys_clk_from_pll() ends up deciding if the PWR_PLL bit should be set based on the state the "Platform Clock" supply had *before* the transition. This sometimes results in PWR_PLL being off, even though *after* the transition PLL1 is configured as sys-clk. This commit removes is_sys_clk_from_pll() instead simply setting / clearing PWR_PLL in rt5640_set_dai_sysclk() based on the selected sys-clk, which fixes this and as a bonus results in a nice cleanup.

[alsa-devel] [PATCH v5 0/2] ASoC: omap: Deprecate omap-pcm for sdma-pcm
by Peter Ujfalusi 11 May '18

11 May '18

Hi, Changes since v4: - Really rebased on a clean tree - Dropped the already applied patches Changes since v3: - Rebased to make sure it applies cleanly (I had one local Kconfig patch) Changes since v2: - Return -ENODEV from sdma_pcm_platform_register() in case !CONFIG_SND_SDMA_SOC Changes since v1: - Rebased on the n810 patches (Kconfig conflict) - Delete the omap-pcm as the last step instead of keeping the .c/.h file. If there is a need it can be resurrected with a simple revert. - I left out the Acked-by from Jarkko for the last patch since I have changed it omap-pcm served us well over the years, but there is no reason to keep it around as we can rely on generic dmaengine_pcm code without the need to maintain custom code. The series has been tested on: omap2 n810, omap3 beagle-xm, omap4 PandaES, omap4 Blaze (SDP), am57xx beagle-x15, dra7 evm.

[alsa-devel] [PATCH v4 0/7] ASoC: omap: Deprecate omap-pcm for sdma-pcm
by Peter Ujfalusi 11 May '18

11 May '18

Hi, Changes since v3: - Rebased to make sure it applies cleanly (I had one local Kconfig patch) Changes since v2: - Return -ENODEV from sdma_pcm_platform_register() in case !CONFIG_SND_SDMA_SOC Changes since v1: - Rebased on the n810 patches (Kconfig conflict) - Delete the omap-pcm as the last step instead of keeping the .c/.h file. If there is a need it can be resurrected with a simple revert. - I left out the Acked-by from Jarkko for the last patch since I have changed it omap-pcm served us well over the years, but there is no reason to keep it around as we can rely on generic dmaengine_pcm code without the need to maintain custom code. The series has been tested on: omap2 n810, omap3 beagle-xm, omap4 PandaES, omap4 Blaze (SDP), am57xx beagle-x15, dra7 evm. McBSP, McASP, McPDM, DMIC and HDMI audio was tested and I have found no issue with them.

[alsa-devel] [PATCH 0/5] ASoC: cirrus: Series of fixes for ep93xx-i2s
by Alexander Sverdlin 11 May '18

11 May '18

This series is a result of long-running debugging of rarely screwed I2S stream out of EP9302 chip. Logic analyser shows that the stream is shifted by one byte (out of 32 bits per sample) which leads to noise intead of original stream. DMA is verified to work fine (no underrun). The issue is only reproducible under high load (CPU or AMBA bus -- not yet clear). This stream corruption happens at the same time I2S controller reports internal FIFO underrun (even though according to documentation, it should handle an underrun gracefully). First two patches are fixing unrelated issues in I2S driver found during debugging of the stream shift. Third one is simplification of the driver to prepare for workaround. Both controller configuration options for TX FIFO underrun handling were tested, both do not work reliable. Hence, this ugly watchdog in the last patch. The whole series is tested on a board similar to EDB9302 (identical in sound part).

[alsa-devel] [PATCH v3] ALSA: core api: define offsets for TLV items
by Ranjani Sridharan 10 May '18

10 May '18

Currently, there are no pre-defined accessors for the elements in topology TLV data. In the absence of such offsets, the tlv data will have to be decoded using hardwired offset numbers 0-N depending on the type of TLV. This patch defines accessor offsets for the type, length, min and mute/step items in TLV data for DB_SCALE type tlv's. These will be used by drivers to decode the TLV data while loading topology thereby improving code readability. The type and len offsets are common for all TLV types. The min and step/mute offsets are specific to DB_SCALE tlv type.

[alsa-devel] [PATCH 0/7] ASoC: omap: Deprecate omap-pcm for sdma-pcm
by Peter Ujfalusi 09 May '18

09 May '18

Hi, omap-pcm served us well over the years, but there is no reason to keep it around as we can rely on generic dmaengine_pcm code without the need to maintain custom code. The series has been tested on: omap3 beagle-xm, omap4 PandaES, omap4 Blaze (SDP), am57xx beagle-x15, dra7 evm. McBSP, McASP, McPDM, DMIC and HDMI audio was tested and I have found no issue with them. I was not able to test on OMAP1 or OMAP2 for various reasons, but mainly because neither Nokia 770 or Nokia n810 audio probes with linux-next. It does not matter if I have omap-pcm or sdma-pcm...

[alsa-devel] Prepare to covert Codec/Platform into Component
by Kuninori Morimoto 09 May '18

09 May '18

Hi Mark, Lars-Peter I will post all prepare patches to convert Codec/Platform into Component. It has 3 steps. 1) add new necessary functions 2) remove/don't use codec hw_write/read 3) remove/don't use codec reg_cache If these are accepted, all prepares were completed. Next, I can post "convert Codec/Platform into Component" patch bomb. These are too many convert patches, to avoid review issue, I will post few of them as sample. 4) sample of don't use rtd->codec 5) sample of convert Platform into Component 6) sample of convert Codec into Component I will post some of "remove" patches too for each steps. I will re-post all "remove" patches if all are accepted. For your review, please consider below. If these are not good, all covert patch doesn't work. 1. use devm_snd_soc_register_component() and remove snd_soc_unregister_component() My patches is using devm_ version function, and removed unregister function. This is not a big deal 2. New flags. Because "Codec" and "CPU/Platform" are using different features, we need to use some new flags. .idle_bias_off/on .ignore_pmdown_time/pmdown_time These are because "CPU/Platform" and "Codec" are using different default value. "Codec" side convert patches are using these. .endianness .non_legacy_dai_naming These are because "Codec" only needs fixup format, and not use "legacy" DAI name. "Codec" side convert patches are using these I added its flags info on each patch. 3. rtd->platform rtd->platform will be removed. Now we can find all rtd connected component by using rtdcom_lookup. rtd->platform will be replaced to snd_soc_rtdcom_lookup(rtd, DRV_NAME); Here, DRV_NAME is platform's component driver name. 4. rtd->codec rtd->codec will be removed. In soc_bind_dai_link(), It is rtd->codec = rtd->codec_dai->codec; And now, DAI has codec and component pointer. So, rtd->codec will be replaced into rtd->codec_dai->component. Best regards --- Kuninori Morimoto

[alsa-devel] [PATCH 0/5][RFC] ASoC: remove Codec/Platform code
by Kuninori Morimoto 09 May '18

09 May '18

Hi Mark Now, all Codec/Platform are replaced to Component. Codec/Platform related code are no longer needed, these patches remove these. But I added [RFC] on these patches because, 1) people want to check/test 2) Media related added new driver is using Codec/Platform style I'm posting replace patch for 2) to Media / ASoC ML, but not yet accepted. (= I think it needs Mark's Acked-by ? I don't know) I think this Codec/Platform remove patch should based on it, otherwise, compile error happen. I'm happy to re-post this remove patch if Media side replace was accepted. Subject: [alsa-devel] [PATCH v3] media: i2c: tda1997: replace codec to component Date: Fri, 6 Apr 2018 05:44:25 +0000 Best regards --- Kuninori Morimoto

[alsa-devel] Applied "ASoC: remove Codec related code" to the asoc tree
by Mark Brown 09 May '18

09 May '18

The patch ASoC: remove Codec related code has been applied to the asoc tree at https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted. You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail.

The patch ASoC: convert platform explanation to component has been applied to the asoc tree at https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted. You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail.

[alsa-devel] [PATCH 00/10] ASoC: remove old platform/codec code
by Kuninori Morimoto 09 May '18

09 May '18

Hi Mark We are now using component base ASoC. Thus, old platform/codec code are no longer needed. These removes it. Then, I very surprised that platform code was already removed :) But, it seems this patch didn't care about documentation and platform specific callback (= .pcm_new/free). 4), 7) handle it. One concern is that it completely removed "platform_list_show" for debugfs. But, I think we want to keep it as "component_list_show" (My original patch did it). 6) reborned it. 8) - 10) are cleanup which can be done *after* removing platform/codec. Kuninori Morimoto (10): 1) ASoC: remove codec hw_write/control_data 2) ASoC: remove codec reg_cache 3) ASoC: remove .get_regmap 4) ASoC: remove unneeded .pcm_new/free 5) ASoC: remove Codec related code 6) ASoC: add component_list_show() 7) ASoC: convert platform explanation to component 8) ASoC: soc.h: merge CONFIG_DEBUG_FS 9) ASoC: soc-core: remove snd_soc_component_add_unlocked() 10) ASoC: soc-core: remove legacy_dai_naming from snd_soc_register_dais() Documentation/sound/soc/platform.rst | 30 +- include/sound/soc-dai.h | 1 - include/sound/soc.h | 289 +---------------- sound/soc/Makefile | 2 +- sound/soc/soc-cache.c | 53 ---- sound/soc/soc-core.c | 585 ++--------------------------------- sound/soc/soc-io.c | 62 ---- sound/soc/soc-jack.c | 22 -- sound/soc/soc-pcm.c | 13 +- 9 files changed, 50 insertions(+), 1007 deletions(-) delete mode 100644 sound/soc/soc-cache.c Best regards --- Kuninori Morimoto

[alsa-devel] [PATCH] ASoC: soc-core: remove legacy_dai_naming from snd_soc_register_dais()
by Kuninori Morimoto 09 May '18

[alsa-devel] [PATCH] ASoC: uniphier: add digital output volume for UniPhier sound system
by Katsuhiro Suzuki 09 May '18

09 May '18

This patch adds controllers for digital volume of PCM output. Volume effects simply linear, not dB scale as follows: Gained PCM = Original * 0x4000 / Volume The value range of volume is from 0x0001 to 0xffff. 0x0000 works as mute. Initial value is 0x4000 (+0dB).

[alsa-devel] [PATCH v4 00/13] ALSA: hda/ca0132: Patch Series for Recon3Di and Sound Blaster Z Support
by Connor McAdams 08 May '18

08 May '18

This patchset adds support for the Sound Blaster Z and the Recon3Di. In order to figure out how to get these cards to work, I made a program called QemuHDADump[1], which uses the trace function of qemu to see interactions with the memory mapped pci BAR space of the card being used in the virtual machine. With this, I obtain the CORB buffer location to get the command verbs, and then dump them each time the buffer rolls over. This program may be useful for fixing other HDA related driver issues where there is no documentation for the device. So far, I have been able to get all features supported on the Sound Blaster Z and the Recon3Di. All output and input effects work, all inputs and outputs work, and just about anything else I can think of. I have also added new controls in order to select the new inputs and outputs, as well as controls to change the effect levels and presets. I have also added the ability to use firmware taken from the Windows drivers of both the Sound Blaster Z and Recon3Di. I am trying to get into contact with Creative to get permission to redistribute these along with the current file included with the Chromebook, but they have not been very responsive. Luckily, the cards work with the Chromebook firmware just fine, although I believe there has to be a reason they have different firmware in Windows. I will not link to the firmwares here, but if you look up my thread on Creative Labs forums, you will find the link to download the firmwares there. I am willing to help get the other non-working cards such as the ZxR and the newer AE-5 working too, but I will need someone willing to run QemuHDADump in a virtual machine in order to get the commands. So, in summary: -This patchset makes the cards work better than they did before (they really didn't work before) -This patchset leaves the original chromebook related stuff alone. Thanks.

[alsa-devel] Help with pcm3168a device tree, and simple-audio-card/simple-scu-audio-card?
by sdaau 08 May '18

08 May '18

Hi all, I am experimenting with PCM3168A audio codec, connected to a Raspberry Pi 3 B running Raspbian 9. I have set up GPIO4 (BCM4) of the Broadcom BCM2837 SoC of the RPi3B as GPCLK0, and use that as SCKI (System clock input) of the PCM3168A; other than that, I have set up the I2S pins of the BCM2837 in I2S/PCM mode, and use the BCLK/LRCLK clock lines to drive both AD and DA (respective) clock lines; and also the PCM DIN and DOUT lines are connected: the PCM3168A codec has 8 (mono, differential) DACs and 6 (mono, differential) ADCs - but I can only test with 2 DACs for stereo out, and 2 ADCs for stereo in, since there is only one line for DIN and DOUT each on the RPi3B/BCM2837 I2S interface. The PCM3168A is controlled by RPi3B's SPI lines, chip select 1. I have had limited success in running this setup with a device tree overlay based on: * simple-audio-card driver: https://github.com/raspberrypi/linux/blob/rpi-4.14.y/sound/soc/generic/simp… * The already existing PCM3168A Linux kernel driver: https://github.com/raspberrypi/linux/blob/rpi-4.14.y/sound/soc/codecs/pcm31… ... however, I cannot get it to properly work, so I hope I can get some help filling in the blanks. First question: * Q1: In the above setup, the pcm3168a.c is a "codec class driver"; but is simple-card.c a platform class or a machine class driver? Also, would the device tree overlay act as a machine class driver, since it "acts as the glue that describes and binds the other component drivers together" (sound/soc/overview.html)? Here are the relevant device tree fragments of the somewhat working device tree overlay, cased on `simple-card.c`: ``` fragment@3 { target = <&spi0>; __overlay__ { #address-cells = <1>; #size-cells = <0>; status = "okay"; pcm3168a: codec@1 { #sound-dai-cells = <0>; reg = <1>; compatible = "ti,pcm3168a"; spi-max-frequency = <1000000>; clocks = <&clocks 38>; // * BCM2835_CLOCK_GP0 * / clock-names = "scki"; pinctrl-names = "default"; pinctrl-0 = <&gpclk0_gpio4>; VDD1-supply = <&vdd_3v3_reg>; VDD2-supply = <&vdd_3v3_reg>; VCCAD1-supply = <&vdd_5v0_reg>; VCCAD2-supply = <&vdd_5v0_reg>; VCCDA1-supply = <&vdd_5v0_reg>; VCCDA2-supply = <&vdd_5v0_reg>; status = "okay"; }; }; }; fragment@4 { /////// a working one: target = <&sound>; slave_sound_overlay: __overlay__ { compatible = "simple-audio-card"; i2s-controller = <&i2s>; status = "okay"; simple-audio-card,name = "my-sound-card"; simple-audio-card,widgets = "Line", "Line In", "Line", "Line Out"; simple-audio-card,routing = "AIN1L", "Line In", "AIN1R", "Line In", "Line Out", "AOUT1L", "Line Out", "AOUT1R"; simple-audio-card,format = "right_j"; //"i2s"; simple-audio-card,mclk-fs = <128>; simple-audio-card,cpu { sound-dai = <&i2s>; }; sound_master: simple-audio-card,codec { sound-dai = <&pcm3168a>; system-clock-frequency = <6144000>; // both these work: 12288000/48000 = 256; 6144000/48000 = 128 }; }; }; ``` When I load this device tree on Raspbian, the following drivers get loaded: ``` pi@raspberrypi:~ $ lsmod Module Size Used by snd_soc_bcm2835_i2s 16384 2 snd_soc_pcm3168a_spi 16384 1 snd_soc_pcm3168a 24576 1 snd_soc_pcm3168a_spi snd_soc_simple_card 16384 0 snd_soc_simple_card_utils 20480 1 snd_soc_simple_card snd_soc_core 204800 4 snd_soc_pcm3168a,snd_soc_simple_card_utils,snd_soc_bcm2835_i2s,snd_soc_simple_card spidev 16384 0 spi_bcm2835 16384 0 snd_compress 20480 1 snd_soc_core snd_pcm_dmaengine 16384 1 snd_soc_core ... snd_pcm 98304 5 snd_pcm_dmaengine,snd_soc_pcm3168a,snd_soc_bcm2835_i2s,snd_bcm2835,snd_soc_core snd_timer 32768 1 snd_pcm snd 69632 7 snd_compress,snd_timer,snd_bcm2835,snd_soc_core,snd_pcm ... ``` ... with relevant syslog messages: ``` kernel: [ 410.676653] bus: 'platform': add driver spi-bcm2835 ... kernel: [ 410.818605] bus: 'platform': add driver snd-soc-dummy kernel: [ 410.819136] bus: 'platform': add driver soc-audio ... kernel: [ 410.830593] bus: 'platform': add driver asoc-simple-card ... kernel: [ 410.833990] bus: 'spi': add driver pcm3168a kernel: [ 410.840144] bus: 'platform': add driver bcm2835-i2s ... kernel: [ 410.857249] asoc-simple-card soc:sound: pcm3168a-dac <-> 3f203000.i2s mapping ok ... systemd-udevd[921]: Execute 'load' 'platform:snd-soc-dummy' systemd-udevd[921]: No module matches 'platform:snd-soc-dummy' ... systemd-udevd[914]: created db file '/run/udev/data/+sound:card1' for '/devices/platform/soc/soc:sound/sound/card1' ... systemd[1]: sys-devices-platform-soc-soc:sound-sound-card1.device: Changed dead -> plugged ... systemd-udevd[921]: handling device node '/dev/snd/pcmC1D0p', devnum=c116:48, mode=0660, uid=0, gid=29 ... systemd-udevd[917]: handling device node '/dev/snd/controlC1', devnum=c116:32, mode=0660, uid=0, gid=29 ... ``` After this, I have a playback card device - but not a capture one: ``` pi@raspberrypi:~ $ aplay -l **** List of PLAYBACK Hardware Devices **** card 0: ... card 1: mysoundcard [my-sound-card], device 0: bcm2835-i2s-pcm3168a-dac pcm3168a-dac-0 [] Subdevices: 1/1 Subdevice #0: subdevice #0 pi@raspberrypi:~ $ arecord -l **** List of CAPTURE Hardware Devices **** pi@raspberrypi:~ $ ``` Note that at this point, with drivers loaded, I do have "card controls" accessible by amixer - but no "simple controls": ``` pi@raspberrypi:~ $ amixer -d -D hw:CARD=mysoundcard info Card hw:CARD=mysoundcard 'mysoundcard'/'my-sound-card' Mixer name : '' Components : '' Controls : 45 amixer: Mixer load hw:CARD=mysoundcard error: Device or resource busy pi@raspberrypi:~ $ amixer -d -D hw:CARD=mysoundcard scontrols amixer: Mixer hw:CARD=mysoundcard load error: Device or resource busy pi@raspberrypi:~ $ amixer -d -D hw:CARD=mysoundcard controls numid=19,iface=MIXER,name='Master Playback Volume' numid=42,iface=MIXER,name='Master Capture Volume' numid=41,iface=MIXER,name='ADC Overflow Flag Polarity' ... numid=13,iface=MIXER,name='DAC4 Zero Flag' pi@raspberrypi:~ $ amixer -d -D hw:CARD=mysoundcard cset iface=MIXER,name='Master Playback Volume' 81% VERIFY ID: numid=0,iface=MIXER,name='Master Playback Volume' numid=19,iface=MIXER,name='Master Playback Volume' ; type=INTEGER,access=rw---R--,values=1,min=0,max=201,step=0 : values=163 | dBscale-min=-100.50dB,step=0.50dB,mute=1 ``` The accessible controls are, in fact, defined in pcm3168a.c (in ...struct snd_kcontrol_new pcm3168a_snd_controls[]) - so, more questions: * Q2: Is the amixer "error: Device or resource busy" an indication that: *no* driver loaded by the device tree overlay, has a definition for any mixer "simple control"? If so, can I set that up via device tree overlay - or do I need to code it in a driver? If coding a driver, which driver should be patched - pcm3168a.c or simple-card.c? * Q3: In the above `amixer cset` of 'Master Playback Volume', I can see `mute=1` in the output. Does that mean master playback is muted? If so, how do I unmute it with amixer? * Q4: As far as I can see, `alsamixer` deals only with "simple controls", not "card controls" (it exits with `cannot load mixer controls: Device or resource busy` as soon as I choose mysoundcard). Is there any ALSA GUI software that can show and manipulate all card controls of a card? Note that pcm3168a.c has notions of a *stereo* DAC and ADC, so the accessible amixer controls refer to ADC1-ADC3 and DAC1-DAC4. Finally, I test this with: ``` pi@raspberrypi:~ $ speaker-test -D hw:CARD=mysoundcard,DEV=0 -c 2 -t sine -f 440 speaker-test 1.1.3 Playback device is hw:CARD=mysoundcard,DEV=0 Stream parameters are 48000Hz, S16_LE, 2 channels Sine wave rate is 440.0000Hz Rate set to 48000Hz (requested 48000Hz) Buffer size range from 128 to 131072 Period size range from 64 to 65536 Using max buffer size 131072 Periods = 4 was set period_size = 32768 was set buffer_size = 131072 0 - Front Left 1 - Front Right Time per period = 2.781788 ... ``` This is what I observe when speaker-test runs: - I've captured I2S and SPI signals with Saleae Logic: GPCLK0 kicks in first, after about 20 ms, SPI sends on MOSI (and SCL) 14 bytes in about 1 ms - immediately after, BCLK starts; and after some 50 ms, LRCLK and DOUT start in synchrony. So, at least from the RPi3B/BCM2837 side, at first glance all seems fine. (I've also used I2S analyzer in the software, and can confirm there's a sinusoid in the I2S DOUT data, though I cannot decode it 100% yet, since I see some discontinuities in the plots) - I've also measured PCM3168A outputs with "analog" scope - unfortunately I had a massive 50 Hz hum where I've measured, so it's difficult to say much with certainty. But basically, when speaker-test runs, there is a significant HF noise appearing on the DAC outputs (which disappears when speaker-test stops). I cannot tell if this is output from the DAC, but faulty, because of misconfiguration of the PCM3168a chip - or if the DAC is actually mute, and this is just noise leaking from GPCLK0 and similar signals (I'll need to find a quieter lab first to re-do measurements) Here are some more questions: * Q5: How would I go about reading the internal configuration registers of the PCM3168A? I guess I could use printk's in pcm3168a.c - but is there an easy/generic way of reading those from user space? * Q6: Is it possible to set internal configuration registers of the PCM3168A from a device tree overlay - say, if I'd like to set up DAC1 and DAC2 (as per datasheet, which is = stereo DAC1 in pcm3168a.c) to work in differential (or single-ended) mode? Note that the device tree overlay sets "right_j" (right justified) digital data exchange (I2S/PCM) format; because whenever I try to set it to "i2s", running speaker-test fails with "Unable to set hw params for playback: Invalid argument" and these syslog messages: ``` pcm3168a spi0.1: 32-bit frames are supported only for slave mode using right justified pcm3168a spi0.1: ASoC: can't set pcm3168a-dac hw params: -22 ``` * Q6: Where did this "32-bit frames" come from, when using format "i2s"? As far as I see it, speaker-test requested S16_LE stereo, meaning 16-bits need to be clocked in when LRCLK is 'L', and 16-bits when LRCLK is 'R' - can't see a "32-bit frame" here anywhere? On the other hand, there is in the PCM3168A datasheet "Table 11. Audio Data Interface Formats and Sampling Rate, Bit Clock, and System Clock Restrictions", with "(1) BCK = 48 fS, 32 fS is supported only in slave mode; BCK = 32 fS is supported only for 16-bit data length." - Does this mean that, since I've requested 16-bit samples, earlier code decided that BCK should be 32 fS, resulting with this "32-bit frame", which then fails at the point it does ?! Can I explicitly override this frame length in the device tree overlay - if so, where? * Q7: I'm very confused about how the master/slave I2S relationship is established in a device tree with `simple-audio-card`. For instance, I've seen `simple-audio-card,bitclock-master` and `,frame-master`, but also `,bitclock-slave` and `,frame-slave`; and yet, my device tree fragment above, uses none of those - and still, at least some of the system works?! So some relationship must have been established implicitly - my guess is (ignoring the `sound_master` label) that since GPCLK0 is set as SCKI of pcm3168a, bcm2835-i2s becomes master, and pcm3168a (codec) becomes slave. Is that correct - if not, how would one derive the actual implied relationship? I should mention, that one of the biggest mysteries for me here is: * Q8: Why is there no capture interface with this usage of `simple-audio-card` in device tree? In fact, I can see nowhere in the above device tree fragment that there is an explicit setup for playback - and yet, I do get a playback interface (and partially, it works)? I would have thought, that the setup of `simple-audio-card,widgets` and `simple-audio-card,routing` (most of the other .dts examples I've seen, have this as the only reference to input/capture vs output/playback) would have been enough to infer that capture interface is needed too, since I refer to "AIN1L", "AIN1R" along with "AOUT1L", "AOUT1R" (all defined in pcm3168a.c) - but apparently, not? Only other example I've seen is `arch/arm/boot/dts/overlays/pibell-overlay.dts`, which sets up `capture_link: simple-audio-card,dai-link@0` and `playback_link: simple-audio-card,dai-link@1` in `target = <&sound>`; but then again, it uses different chips for input and output - is this approach preferable, also when a single chip de als with both playback and capture? Now, an interesting thing is that, even in my above device tree fragment, if I just change `compatible = "simple-audio-card";` to `compatible = "simple-scu-audio-card";` - drivers will typically load with the device tree, but speaker-test will fail with a segfault at very start. To be sure, I tried writing another device tree fragment for "simple-scu-audio-card": ``` fragment@4 { target = <&sound>; slave_sound_overlay: __overlay__ { compatible = "simple-scu-audio-card"; i2s-controller = <&i2s>; status = "okay"; simple-audio-card,name = "my-sound-card"; simple-audio-card,format = "i2s"; simple-audio-card,convert-rate = <48000>; // simple-scu-card.txt (simple-scu-audio-card); prob no effect with simple-card.c (simple-audio-card) only; //simple-audio-card,prefix = "pcm3168a"; // NOTE: this causes the // ASoC: no source widget found for AOUT1L! // without ,widgets: "ASoC: no sink widget found for Line Out/In" simple-audio-card,widgets = //~ "Line", "Line In", "Line", "Line Out"; simple-audio-card,routing = "Line Out","AOUT1L", "Line Out","AOUT1R"; //, //~ "AIN1L","Line In", //~ "AIN1R","Line In"; //"Playback","DAC1"; //passes without simple-audio-card,widgets - but segfaults sndcpu: simple-audio-card,cpu { sound-dai = <&i2s>; }; sndcodec: simple-audio-card,codec { sound-dai = <&pcm3168a>; system-clock-frequency = <12288000>; }; }; }; ``` The funny thing here is - even if the "Line In" references are commented in ,routing - still, both a playback and a capture interface appear, along with the load of device tree and corresponding drivers! However, speaker-test causes segfault with a stack trace like: ``` kernel: [20819.557733] Unable to handle kernel NULL pointer dereference at virtual address 000000b0 ... kernel: [20819.557997] Hardware name: BCM2835 kernel: [20819.558008] task: 9f31ad00 task.stack: 9f3c8000 kernel: [20819.558148] PC is at is_connected_output_ep+0x1c/0x1fc [snd_soc_core] kernel: [20819.558274] LR is at snd_soc_dapm_dai_get_connected_widgets+0x90/0x1e4 [snd_soc_core] ...

And finally, in general: * Q11: I generally want to use PCM3168A chip DAC1 and DAC2 as stereo OUT (driver: stereo DAC1), and chip ADC1 and ADC2 as stereo IN (driver: stereo ADC1). Am I better off basing myself on `simple-audio-card`, or on `simple-scu-audio-card`, in the device tree overlay? In fact, is it possible to set up this kind of operation using existing drivers in a device tree overlay - or would I have to add my own driver code (either as patch of existing drivers, or as "my own" driver, possibly started from an existing driver)? * Q12: I'd also want to use (driver: stereo DAC1) and (driver: stereo ADC1) in full-duplex mode. Can this be set up solely via `dai-tdm-slot-num`, `-width`, `-tx-mask` and `-rx-mask` under `simple-audio-card,cpu` in device tree overlay - or would I have to add my own driver code (either patching, or "my own")? Many thanks in advance for any pointers!

[alsa-devel] [PATCH v3 0/9] ALSA: hda/ca0132: Patch Series for Recon3Di and Sound Blaster Z Support
by Connor McAdams 07 May '18

07 May '18

This patchset adds support for the Sound Blaster Z and the Recon3Di. In order to figure out how to get these cards to work, I made a program called QemuHDADump[1], which uses the trace function of qemu to see interactions with the memory mapped pci BAR space of the card being used in the virtual machine. With this, I obtain the CORB buffer location to get the command verbs, and then dump them each time the buffer rolls over. This program may be useful for fixing other HDA related driver issues where there is no documentation for the device. So far, I have been able to get all features supported on the Sound Blaster Z and the Recon3Di. All output and input effects work, all inputs and outputs work, and just about anything else I can think of. I have also added new controls in order to select the new inputs and outputs, as well as controls to change the effect levels and presets. I have also added the ability to use firmware taken from the Windows drivers of both the Sound Blaster Z and Recon3Di. I am trying to get into contact with Creative to get permission to redistribute these along with the current file included with the Chromebook, but they have not been very responsive. Luckily, the cards work with the Chromebook firmware just fine, although I believe there has to be a reason they have different firmware in Windows. I will not link to the firmwares here, but if you look up my thread on Creative Labs forums, you will find the link to download the firmwares there. I am willing to help get the other non-working cards such as the ZxR and the newer AE-5 working too, but I will need someone willing to run QemuHDADump in a virtual machine in order to get the commands. So, in summary: -This patchset makes the cards work better than they did before (they really didn't work before) -This patchset leaves the original chromebook related stuff alone. Thanks. [1] https://github.com/Conmanx360/QemuHDADump Bugs: ------------------------------------------------------------------------------- Recon3Di: (Reported by Mariusz Ceier) ******************* -Occasionally switching between rear and front mic breaks the input until computer is shutdown or put to sleep. -Surround Sound works, but is inconsistent. Sometimes, just updating the volume fixes it, and sometimes, it requires a restart. Sound Blaster Z: ******************* -none that I'm aware of. Version changes: ------------------------------------------------------------------------------- v1: ******************* -Massive patch formatting failure, please ignore v1. v2: ******************* -Fixed patch formatting failure. v3: ******************* -Fixed mem_base unmap, instead of checking for QUIRK_SBZ on exit, have it check if the area is mapped, and if it is, unmap it. Also make it unmap after all other commands are finished. -Change notification of failure to map mem_base from codec_dbg to codec_warn, and use codec_info to tell the user that their card might have been incorrectly identified as a Sound Blaster Z. -Remove commented out commands in sbz_exit_chip function, only reintroduce them when their functions are defined.

[alsa-devel] [PATCH v3 00/20] Allow compile-testing NO_DMA (drivers)
by Geert Uytterhoeven 07 May '18

07 May '18

Hi all, As of v4.17-rc1, patch series "[PATCH v2 0/5] Allow compile-testing NO_DMA (core)" (https://lkml.org/lkml/2018/3/16/435) has been included upstream, and drivers using the DMA API can be compile-tested on platforms selecting NO_DMA. This follow-up patch series removes dependencies on HAS_DMA for symbols that already have platform dependencies implying HAS_DMA, which increases compile-coverage. Please apply to your tree if appropriate. Changes compared to v2: - Add Acked-by, - Rebased to v4.17-rc1, dropping applied patch for scsi/hisi_sas, - Handle new VIDEO_RENESAS_CEU symbol, - Drop obsolete note about FSL_FMAN. Changes compared to v1: - Add Reviewed-by, Acked-by, - Drop dependency of SND_SOC_LPASS_IPQ806X on HAS_DMA, - Drop dependency of VIDEOBUF{,2}_DMA_{CONTIG,SG} on HAS_DMA, - Drop new dependencies of VIDEO_IPU3_CIO2, DVB_C8SECTPFE, and MTD_NAND_MARVELL on HAS_DMA, - Split in per-subsystem patches, - Split-off the core part in a separate series. This series is against v4.17-rc1. It can also be found at https://git.kernel.org/pub/scm/linux/kernel/git/geert/linux-m68k.git/log/?h… It has been compile-tested with allmodconfig and allyesconfig for m68k/sun3, and has received attention from the kbuild test robot. Thanks for applying!

Hi, Changes since v2: - Return -ENODEV from sdma_pcm_platform_register() in case !CONFIG_SND_SDMA_SOC Changes since v1: - Rebased on the n810 patches (Kconfig conflict) - Delete the omap-pcm as the last step instead of keeping the .c/.h file. If there is a need it can be resurrected with a simple revert. - I left out the Acked-by from Jarkko for the last patch since I have changed it omap-pcm served us well over the years, but there is no reason to keep it around as we can rely on generic dmaengine_pcm code without the need to maintain custom code. The series has been tested on: omap2 n810, omap3 beagle-xm, omap4 PandaES, omap4 Blaze (SDP), am57xx beagle-x15, dra7 evm. McBSP, McASP, McPDM, DMIC and HDMI audio was tested and I have found no issue with them. I was not able to test on OMAP1 for various reasons, but mainly because the Nokia 770 audio is not supported in mainline...

Probably I was not clear; Why ALSA picked period_size of 2042 bytes when the minimum period bytes specified is 4084? Reason for this question is probably my wrong understanding. AFAIK: period_bytes_min specified in hw_params means the minimum bytes after which audio driver can expect an interrupt. So, total buffer size should be multiple of period_bytes_min or multiple of user provided period size if it is greater than period_bytes_min. So, if the above understanding is right then buffer size should have been 4084*2 (number of periods asked by user). Ultimately the question is how period size is calculated given min_period_bytes, max_period_bytes, buffer_bytes_max from pcm_hardware and user supplied period size and period count? I tried looking into the code but looks like there is lot of macro magic going on in pcm native layer. > cat sub0/hw_params > > access: RW_INTERLEAVED > format: S16_LE > subformat: STD > channels: 1 > rate: 16000 (16000/1) > period_size: 2042 > buffer_size: 4084 >>The actual values of period_size and period_count are returned by >>pcm_open().

[alsa-devel] Buffer size calculation based on period size
by noman pouigt 04 May '18

I am at my wits end trying to figure out how period_size is being calculated in pcm_native layer based on period_size and period_count being set by the userspace. I am using tinycap to capture the audio and setting below settings: bitwidth = 16 rate = 16000 channel = 1 period_size = 320 period_count = 2 I am wondering how is below period_size and buffer_size calculated? Shouldn't period_size of 320 bytes and period_count of 2 fail? cat sub0/hw_params access: RW_INTERLEAVED format: S16_LE subformat: STD channels: 1 rate: 16000 (16000/1) period_size: 2042 buffer_size: 4084 And this is my settings in pcm_hardware structure: static struct snd_pcm_hardware s1000_pcm_hw = { .buffer_bytes_max = 1024*1024, .period_bytes_min = 4084, .period_bytes_max = (1024*1024)/2, .periods_min = 2, .periods_max = 32, };

[alsa-devel] [PATCH] ALSA: dice: support transmission mode at 176.4/192.0 kHz for M-Audio 610/2626
by Takashi Sakamoto 04 May '18

04 May '18

At highest sampling transmission frequency, ALSA dice driver detects jumbo payload in tx packets from M-Audio 610/2626. $ dmesg snd_dice fw1.0: Detect jumbo payload: 0388 0348 Usual dice devices have a quirk called as dual-wire incompliant to IEC 61883-6 at highest sampling transmission frequency. On the other hand, M-Audio 610/2626 is compliant. This is a reason of the detection of jumbo payload. This commit adds support compliant transmission mode. For these devices, tx packets are correctly handled by this driver, while rx packets can't make these devices generate sound, unfortunately. The other factor affects it.

[alsa-devel] [PATCH 1/9] R3Di and SBZ quirk entires + alt firmware loading
by Connor McAdams 04 May '18

04 May '18

This patch adds PCI quirk ID's for the Sound Blaster Z and Recon3Di. Only the currently tested ID's have been added. This patch also adds the ability to load alternative firmwares for each card, the firmwares can be obtained from within the Windows driver. The Recon3Di uses "ctefx-r3di.bin" and the Sound Blaster Z uses "ctefx-sbz.bin". If the alternative firmware for the given quirk is not found, the original ctefx.bin will be used.

[alsa-devel] [PATCH 1/9] R3Di and SBZ quirk entires + alt firmware loading
by Connor McAdams 04 May '18

04 May '18

This patch adds PCI quirk ID's for the Sound Blaster Z and Recon3Di. Only the currently tested ID's have been added. This patch also adds the ability to load alternative firmwares for each card, the firmwares can be obtained from within the Windows driver. The Recon3Di uses "ctefx-r3di.bin" and the Sound Blaster Z uses "ctefx-sbz.bin". If the alternative firmware for the given quirk is not found, the original ctefx.bin will be used. This has been confirmed to work for both the R3Di and the SBZ. This patch also makes the character array *dirstr a const.

[alsa-devel] [PATCH v4] ASoC: tas6424: Allow disabling auto diagnostics for faster power-on
by Jean-Jacques Hiblot 04 May '18

04 May '18

The TAS6424 incorporates both DC-load and AC-load diagnostics which are used to determine the status of the load. The DC diagnostics runs when any channel is directed to leave the Hi-Z state and enter the MUTE or PLAY state. The DC diagnostics are turned on by default but, if a fast startup without diagnostics is required, the diagnostics can be disabled using a dedicated ALSA control.

[alsa-devel] [PATCH] ALSA: usb-audio: Clean up mixer element list traverse
by Takashi Iwai 03 May '18

Introduce a new macro for iterating over mixer element list for avoiding the open codes in many places. Also the open-coded container_of() and the forced cast to struct usb_mixer_elem_info are replaced with another simple macro, too. No functional changes but just readability improvement.

Hi Pierre-Louis, I'm finally wrapping up my rt5640 jack-detect work, as such I'm currently testing speaker + headphones + internal mic + headset-mic + jack-detect functionality on the 10 different x86 devices with a rt5640 codec which I've gathered. 2 of them stand out in that they use the BYTCR SoC, but don't have the ACPI table for detecting if SSP0 AIF1 or AIF2 should be used. Currently the driver defaults to AIF2 in this case. As the somewhat wildcard-ish DMI quirk for boards where the sys_vendor is "Insyde" (which applies to a lot of generic designs) shows: { .callback = byt_rt5640_quirk_cb, .matches = { DMI_MATCH(DMI_SYS_VENDOR, "Insyde"), }, .driver_data = (void *)(BYT_RT5640_IN3_MAP | BYT_RT5640_MCLK_EN | BYT_RT5640_SSP0_AIF1), }, AIF1 seems to be a better default both models without the ACPI table which I've here, a HP pavilion X2 and a Toshiba Click Mini L9W-B need a quirk to use AIF1. So I was wondering if there was a specific rationale for the AIF2 default and if it would not be better to change the default to AIF1 (which will unfortunately bring a chance of regressions) ? Regards, Hans

[alsa-devel] [BUG - REPORT] ALC892 not working
by Xristos Boul 03 May '18

03 May '18

Hi everyone, I'm having a problem with my line-out port not being working properly. Specifically it can't play audio when the 'alsamixer' auto-mute mode is enabled, so sound is coming only from the headphones.However, when auto-mute is disabled the sound is coming from both ports simultaneously. I'm using the Asus Z170-A mobo with ALC892 codec, OS: Arch I ran alsa-info.sh on both cases and i saw that the Pin-Complex 0x14 had 'Pin-ctls: OUT' when auto-mute was disabled whereas when auto-mute was enabled it was 'Pin-ctls: 0x00' (as it currenly is). So i ran HDA-analyzer tool and changed that widget setting to 'OUT' and obviously i produced the same behaviour like when i disabled 'auto-mute' (again sound coming from both ports) and also in all cases PulseAudio lists the 'Line-out' port as 'unplugged'. Also 2 more things: 1st: In BIOS when i changed the driver for the Front panel from 'HD-Audio' to 'AC97' and the ports worked correctly, however no 'auto-mute' mode was available so i had to mute the ports manually when i plugged/unplugged the headphones for e.x I tried uninstalling PulseAudio to see if it was the case but the problem persisted so i think it really is some codec problem since i also have a similar problem in Windows OS. 2nd: When i unplugged the Front-panel connection from the mobo the port played correctly. So is it maybe a mixer problem or something related? Finally i tried every 'model' parameter from HD-Audio-Models.txt for ALC892 but got nothing. In any case i'm attaching the current alsa-info.sh. If you would like i could also send alsa-info.sh for all those cases above. I don't think i'm alone in this issue but i would greatly appreciate the help! Thanks in advance.

[alsa-devel] [PATCH v2] ASoC: da7219: read fmw property to get mclk for non-dts systems
by Akshu Agrawal 03 May '18

Non-dts based systems can use ACPI DSDT to pass on the mclk to da7219. This enables da7219 mclk to be linked to system clock. Enable/Disable of the mclk is already handled in the codec so platform drivers don't have to explicitly do handling of mclk.

by Colin King 03 May '18

03 May '18

From: Colin Ian King <colin.king(a)canonical.com> Currently, the check that ret_val is not -ENOENT is always true and the quirk bit BYT_RY5651_MCLK_EN is never being cleared because ret_val is always zero at this point from a previous assignment earlier on. I believe that ret_val should actually be assigned to the return from devm_clk_get() as this can return -ENOENT (from a deeper call to clk_get_sys) and that was the original intention to check this.

[alsa-devel] [PATCH 0/6] usb-audio: quirks for Dell WD15 dock and some extensions
by Takashi Iwai 02 May '18

02 May '18

Hi, here is a patch set for adding quirks and some new extensions for Dell WD15 dock. The first patch is the resend of the previous post, and the rest are new. Basically it adds a new "Keep Interface" control for the card to skip resetting the USB interface per stream manipulation. It helps for reducing the long pause before each start of stream on Dell WD15 dock. OTOH, this was confirmed to be harmless on some dock early firmware version, so we can't set it statically in the driver. So, instead, the feature is exposed as a control element so that user can flip dynamically. This feature may be useful for other USB audio devices as well. Another extension is to allow the quirk entry to override the card longname field. This is needed to give a proper UCM profile. WD15 dock provides two streams, one for the headphone and another for the line out. It's a good example for using a UCM profile.

Hi, This patchset updates my previous one: [alsa-devel] [PATCH v2 00/11] ALSA: dice: use cache of stream formats to generate PCM rules/constraints http://mailman.alsa-project.org/pipermail/alsa-devel/2018-April/135330.html Once, ALSA dice driver cached stream formats to generate PCM constraints/rules. The cache is created by changing current sampling transmission frequency step by step directly at unit probing process. This feature was dropped because it changes state of clock on target device thus it's against users' expectation[1]. However this is not necessarily convenient because reconfiguration of sampling rate is not available. TC Applied Technologies (TCAT) has extended protocol for DICE interface, a.k.a EAP (Extended Application Protocol). In this extension, drivers can retrieve information of stream formats without changing state of target unit. Fortunately, this protocol is supported widely by many models. This patchset regain the cache to generate PCM constraints/rules by using this protocol. Userspace applications can reconfigure sampling rate via ALSA PCM interface. For units which doesn't support the extension, available set of sampling rate is still restricted at current sampling transmission frequency. This is also inconvenient and this patchset introduces a solution. Structure for unit entry (struct ieee1394_device_id) has a member for unit-specific data. This patchset uses it for callback function to handle hard-coded stream format. In this time, I adopt this way for some known models produced by TC Electronic and Alesis. If users find their models still have restrictions in a point of available sampling transmission frequency, it's preferable to work for this way. Changes from v2: - use robust representation to calcurate mode of sampling transmission frequency.

As discussed in [1], ASoC core supports multi codec DAIs on a DAI link. However it does not do so for CPU DAIs. So, add support for multi CPU DAIs on a DAI Link by adding multi CPU DAI in Card instantiation, suspend and resume functions, PCM ops, stream handling functions and DAPM.

[alsa-devel] [PATCH v2 0/5] ALSA: xen-front: Add Xen para-virtualized frontend driver
by Oleksandr Andrushchenko 02 May '18

02 May '18

From: Oleksandr Andrushchenko <oleksandr_andrushchenko(a)epam.com> Please note: this patch series depends on [3]. This patch series adds support for Xen [1] para-virtualized sound frontend driver. It implements the protocol from include/xen/interface/io/sndif.h with the following limitations: - mute/unmute is not supported - get/set volume is not supported Volume control is not supported for the reason that most of the use-cases (at the moment) are based on scenarious where unprivileged OS (e.g. Android, AGL etc) use software mixers. Both capture and playback are supported. Corresponding backend, implemented as a user-space application, can be found at [2]. Thank you, Oleksandr Changes since v1: ***************** 1. Moved driver from sound/drivers to sound/xen 2. Coding style changes to better meet Linux Kernel 3. Added explicit back and front synchronization In order to provide explicit synchronization between backend and frontend the following changes are introduced in the protocol: - add new ring buffer for sending asynchronous events from backend to frontend to report number of bytes played by the frontend (XENSND_EVT_CUR_POS) - introduce trigger events for playback control: start/stop/pause/resume - add "req-" prefix to event-channel and ring-ref to unify naming of the Xen event channels for requests and events 4. Added explicit back and front parameter negotiation In order to provide explicit stream parameter negotiation between backend and frontend the following changes are introduced in the protocol: add XENSND_OP_HW_PARAM_QUERY request to read/update configuration space for the parameters given: request passes desired parameter's intervals/masks and the response to this request returns allowed min/max intervals/masks to be used.

[alsa-devel] [PATCH] ALSA: usb-audio: Initialize Dell Dock playback volumes
by Takashi Iwai 02 May '18

02 May '18

In the early commit adcdd0d5a1cb ("ALSA: usb-audio: Skip volume controls triggers hangup on Dell USB Dock"), we add the mixer quirks for Dell dock to skip two mixer FU's for playback. This supposed that the device has always the proper initial volume, but it doesn't seem always correct. This patch adds the explicit initialization of the volumes to the fixed 0dB at the device probe time. Also, such a fixup is needed after the resume, so a new function is hooked to the resume callback as well.

[alsa-devel] [PATCH] ALSA: hda - Enforce CONFIG_SND_DYNAMIC_MINORS for HDMI/DP codec
by Takashi Iwai 02 May '18

02 May '18

The DP-MST support requires more PCM streams than usual, hence CONFIG_SND_DYNAMIC_MINORS is almost mandatory. Currently the driver just warns and continues even if streams are missing, but it doesn't seem to enough convince users to switch to the modern setup. This patch adds the enforced selection of CONFIG_SND_DYNAMIC_MINORS from CONFIG_SND_HDA_CODEC_HDMI for covering that.

[alsa-devel] [PATCH 0/5] conf/ucm: chtrt5645: Various updates
by Hans de Goede 02 May '18

02 May '18

Hi All, Here is a series of chtrt5645 UCM updates, the first 2 patches bring in some fixes for the generic config from: https://github.com/plbossart/UCM The 3th patch adds some analog mic input fixes, together these 3 patches bring the generic chtrt5645 config in sync with the newer chtrt5645-mono-speaker-analog-mic config, but then for stereo speakers. The 4th and the 5th patch add long-name using board/model specific configs for the Asus T100HA and Lenovo Miix 320, these use a digital mic connected to the DMIC1 resp. DMIC2. input. The generic chtrt5645 config has been tested on a Lenovo Miix 310 and a Kazam Vision tablet, both of which feature stereo speakers and an analog microphone. The Asus T100HA and Lenovo Miix 320 configs have been tested on the resp. models they apply to. Regards, Hans

[alsa-devel] [PATCH RFC] ASoC: dai playback_active and capture_active may be greater than 1
by Jerome Brunet 02 May '18

02 May '18

At the moment playback_active and capture_active are using only 1 bit so the maximum active count is 1. However, snd_soc_runtime_activate() may be called several time on the same dai. This happens when a dai is part of several dai_links. It is often the case for "snd-soc-dummy-dai". This is a problem if snd_soc_runtime_activate() is called an even number of times on a dai. In this case the active count overflow back to 0. As consequence, ASoC functions, such as soc_dpcm_runtime_update(), won't run correctly. Storing these usage counts on plain 'unsigned int' solves the problem. Fixes: f0fba2ad1b6b ("ASoC: multi-component - ASoC Multi-Component Support") Signed-off-by: Jerome Brunet <jbrunet(a)baylibre.com> --- Hi, I found this problem while working on ASoC support for a new platform. During a playback, using DPCM, if I changed the backend dai, nothing happened, old backend path was not pruned, new backend path was not added. Here is how it goes: 1 FE and 2 BE, all 3 using snd-soc-dummy-dai for the codec_dai (ATM). On playback start: - BE #1 activates and increments snd-soc-dummy-dai's playback_active - FE activates and increments snd-soc-dummy-dai's playback_active The playback works but snd-soc-dummy-dai's playback_active value is now 0. Through a mux kcontrol, change BE client of FE, from BE #1 to BE #2. -> trigger soc_dpcm_runtime_update(). -> checks fe's codec_dai playback_active which is zero so playback path processing is skipped, keeping the old invalid path. include/sound/soc-dai.h | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/include/sound/soc-dai.h b/include/sound/soc-dai.h index 8ad11669e4d8..35ebb0be5114 100644 --- a/include/sound/soc-dai.h +++ b/include/sound/soc-dai.h @@ -294,8 +294,8 @@ struct snd_soc_dai { struct snd_soc_dai_driver *driver; /* DAI runtime info */ - unsigned int capture_active:1; /* stream is in use */ - unsigned int playback_active:1; /* stream is in use */ + unsigned int capture_active; /* stream usage count */ + unsigned int playback_active; /* stream usage count */ unsigned int probed:1; unsigned int active; -- 2.14.3

[alsa-devel] [PATCH v3 0/3] ASoc: TAS6424: Add support for mute, standby, and faster power on
by Jean-Jacques Hiblot 01 May '18

01 May '18

mute and standby pins are available on the codec. If they are connected, they should be managed by the driver, instead of relying on gpio hogs or on the initial state of the GPIOs. This series also includes a patch to improve the start-up time of the channels by disabling built-in DC diagnostics. Those diagnosdtics basically serve to detect : - wires shorted together - wire shorted to ground or vbat - wire disconnected This is not useful for all platforms and the addition to the startup time is quite noticeable (230ms). The diagnostics can be enabled/disabled using a dedicated ALSA control. Changes in v3: - use SOC_SINGLE_STROBE() to register the "auto diagniostics switch" control Changes in v2: - use a ALSA control to enable/disable the auto diagnostics instead of relying on a DTS property. - fixed typos - use gpios (plural) instead of gpio in the documentation of the bindings Jean-Jacques Hiblot (3): ASoC: tas6424: Add support for the standby pin ASoC: tas6424: Add support for the mute pin ASoC: tas6424: Allow disabling auto diagnostics for faster power-on .../devicetree/bindings/sound/ti,tas6424.txt | 2 + sound/soc/codecs/tas6424.c | 72 +++++++++++++++++++++- sound/soc/codecs/tas6424.h | 4 ++ 3 files changed, 75 insertions(+), 3 deletions(-) -- 2.7.4

[alsa-devel] [PATCH v2 0/6] ARM/ASoC: omap: n810 audio support
by Peter Ujfalusi 01 May '18

01 May '18

Hi, Changes since v1: - Fixed up the aic33 dts patch with missing entries needed for capture - Added comment and new widget for the non working HS Mic The verification of the sdma-pcm on OMAP2 got delayed by non working audio on n810. With the following patches audio works on n810 (both with the old omap-pcm and the new sdma-pcm). I believe the DTS and ASoC patches are fine to go via different tree, but I wanted to keep the patches together for easier testing. The series does not have any dependencies, I will rebase the sdma-pcm series on top of this and resend. Playback to Speaker, Headset is working. Capture from DMIC is working. Capture from HS mic is not working due to missing mic bias (from Retu/Vilma).

[alsa-devel] [PATCH v2 00/13] ALSA: dice: use cache of stream formats to generate PCM rules/constraints
by Takashi Sakamoto 01 May '18

01 May '18

Hi, This patchset updates my previous one: [alsa-devel] [PATCH 00/11] ALSA: dice: use cache of stream formats to generate PCM rules/constraints http://mailman.alsa-project.org/pipermail/alsa-devel/2018-April/134983.html Once, ALSA dice driver cached stream formats to generate PCM constraints/rules. The cache is created by changing current sampling transmission frequency step by step directly at unit probing process. This feature was dropped because it changes state of clock on target device thus it's against users' expectation[1]. However this is not necessarily convenient because reconfiguration of sampling rate is not available. TC Applied Technologies (TCAT) has extended protocol for DICE interface, a.k.a EAP (Extended Application Protocol). In this extension, drivers can retrieve information of stream formats without changing state of target unit. Fortunately, this protocol is supported widely by many models. This patchset regain the cache to generate PCM constraints/rules by using this protocol. Userspace applications can reconfigure sampling rate via ALSA PCM interface. For units which doesn't support the extension, available set of sampling rate is still restricted at current sampling transmission frequency. This is also inconvenient and this patchset introduces a solution. Structure for unit entry (struct ieee1394_device_id) has a member for unit-specific data. This patchset uses it for callback function to handle hard-coded stream format. In this time, I adopt this way for some known models produced by TC Electronic and Alesis. If users find their models still have restrictions in a point of available sampling transmission frequency, it's preferable to work for this way. Changes from v1: - rename members for the channel cache. - add minor refactoring. - fix a bug that sampling transmission frequency is not changed via ALSA PCM interface. - fix a bug that current stream formats are reused after changing sampling transmission frequency.

[alsa-devel] [PATCH v2 0/7] ASoC: omap: Deprecate omap-pcm for sdma-pcm
by Peter Ujfalusi 30 Apr '18

30 Apr '18

Hi, Changes since v1: - Rebased on the n810 patches (Kconfig conflict) - Delete the omap-pcm as the last step instead of keeping the .c/.h file. If there is a need it can be resurrected with a simple revert. - I left out the Acked-by from Jarkko for the last patch since I have changed it omap-pcm served us well over the years, but there is no reason to keep it around as we can rely on generic dmaengine_pcm code without the need to maintain custom code. The series has been tested on: omap2 n810, omap3 beagle-xm, omap4 PandaES, omap4 Blaze (SDP), am57xx beagle-x15, dra7 evm. McBSP, McASP, McPDM, DMIC and HDMI audio was tested and I have found no issue with them. I was not able to test on OMAP1 for various reasons, but mainly because the Nokia 770 audio is not supported in mainline...

[alsa-devel] [PATCH] ASoC: da7219: read fmw property to get mclk for non-dts systems
by Akshu Agrawal 30 Apr '18

30 Apr '18

Non-dts based systems can use ACPI DSDT to pass on the mclk to da7219. This enables da7219 mclk to be linked to system clock. Enable/Disable of the mclk is already handled in the codec so platform drivers don't have to explicitly do handling of mclk.

[alsa-devel] KASAN: use-after-free in loopback_active_get
by DaeRyong Jeong 30 Apr '18

30 Apr '18

We report the crash: KASAN: use-after-free in loopback_active_get This crash has been found in v4.17-rc1 using RaceFuzzer (a modified version of Syzkaller), which we describe more at the end of this report. Our analysis shows that the race occurs when invoking two syscalls concurrently, ioctl$SNDRV_CTL_IOCTL_ELEM_READ and syz_open_dev$audion. kernel config: https://kiwi.cs.purdue.ed/static/race-fuzzer/KASAN_use-after-free_in_loopba… Analysis: When there is a race between sound/drivers/aloop.c:895 (loopback_active_get) and sound/drivers/aloop.c:678 (free_cable), the retrieved cable pointer in loopback_active_get() may point to the freed memory region. When loopback_active_get() dereferences this pointer, use-after-free occurs. Possible CPU execution: CPU0 CPU1 loopback_active_get() free_cable() ---- ---- struct loopback_cable *cable = ... loopback->cables[substream->number][dev] = NULL; kfree(cable); cable->running <-- Use-after-free Call Sequence: CPU0 loopback_active_get snd_ctl_elem_read snd_ctl_elem_read_user snd_ctl_ioctl CPU1 free_cable loopback_close snd_pcm_release_substream snd_pcm_release_substream snd_pcm_oss_release_file snd_pcm_oss_release_file snd_pcm_oss_release We observed that snd_pcm_oss_release() is called during the open("/dev/audio1") syscall. In our configuration, the function do_dentry_open() returns -EINVAL since below if statement is evaluated as true. if ((f->f_flags & O_DIRECT) (!f->f_mapping->a_ops || !f->f_mapping->a_ops->direct_IO)) Therefore, fput() is called and snd_pcm_oss_release() is called as a pending work before returning to the user space. But we suspect that the insufficient locking between snd_ctl_ioctl() and snd_pcm_oss_release(), not the vfs_layer, is the cause of the crash. -------- Read of size 4 at addr ffff88023aa4899c by task

version of Syzkaller, specifically tailored to find race condition bugs in the Linux kernel. While we leverage many different technique, the notable feature of RaceFuzzer is in leveraging a custom hypervisor (QEMU/KVM) to interleave the scheduling. In particular, we modified the hypervisor to intentionally stall a per-core execution, which is similar to supporting per-core breakpoint functionality. This allows RaceFuzzer to force the kernel to deterministically trigger racy condition (which may rarely happen in practice due to randomness in scheduling). RaceFuzzer's C repro always pinpoints two racy syscalls. Since C repro's scheduling synchronization should be performed at the user space, its reproducibility is limited (reproduction may take from 1 second to 10 minutes (or even more), depending on a bug). This is because, while RaceFuzzer precisely interleaves the scheduling at the kernel's instruction level when finding this bug, C repro cannot fully utilize such a feature. Please disregard all code related to "should_hypercall" in the C repro, as this is only for our debugging purposes using our own hypervisor.

[alsa-devel] [PATCH] ALSA: dice: fix kernel NULL pointer dereference due to invalid calculation for array index
by Takashi Sakamoto 29 Apr '18

29 Apr '18

At a commit f91c9d7610a ('ALSA: firewire-lib: cache maximum length of payload to reduce function calls'), maximum size of payload for tx isochronous packet is cached to reduce the number of function calls. This cache was programmed to updated at a first callback of ohci1394 IR context. However, the maximum size is required to queueing packets before starting the isochronous context. As a result, the cached value is reused to queue packets in next time to starting the isochronous context. Then the cache is updated in a first callback of the isochronous context. This can cause kernel NULL pointer dereference in a below call graph: (sound/firewire/amdtp-stream.c) amdtp_stream_start() ->queue_in_packet() ->queue_packet() (drivers/firewire/core-iso.c) ->fw_iso_context_queue() ->struct fw_card_driver.queue_iso() (drivers/firewire/ohci.c) = ohci_queue_iso() ->queue_iso_packet_per_buffer() buffer->pages[page] The issued dereference occurs in a case that: - target unit supports different stream formats for sampling transmission frequency. - maximum length of payload for tx stream in a first trial is bigger than the length in a second trial. In this case, correct number of pages are allocated for DMA and the 'pages' array has enough elements, while index of the element is wrongly calculated according to the old value of length of payload in a call of 'queue_in_packet()'.

[alsa-devel] [PATCH v2 0/3] ASoc: TAS6424: Add support for mute, standby, and faster power on
by Jean-Jacques Hiblot 28 Apr '18

28 Apr '18

mute and standby pins are available on the codec. If they are connected, they should be managed by the driver, instead of relying on gpio hogs or on the initial state of the GPIOs. This series also includes a patch to improve the start-up time of the channels by disabling built-in DC diagnostics. Those diagnosdtics basically serve to detect : - wires shorted together - wire shorted to ground or vbat - wire disconnected This is not useful for all platforms and the addition to the startup time is quite noticeable (230ms). The diagnostics can be enabled/disabled using a dedicated ALSA control. Changes in v2: - use a ALSA control to enable/disable the auto diagnostics instead of relying on a DTS property. - fixed typos - use gpios (plural) instead of gpio in the documentation of the bindings Jean-Jacques Hiblot (3): ASoC: tas6424: Add support for the standby pin ASoC: tas6424: Add support for the mute pin ASoC: tas6424: Allow disabling auto diagnostics for faster power-on .../devicetree/bindings/sound/ti,tas6424.txt | 2 + sound/soc/codecs/tas6424.c | 78 +++++++++++++++++++++- sound/soc/codecs/tas6424.h | 4 ++ 3 files changed, 81 insertions(+), 3 deletions(-) -- 2.7.4

For devices implemented as a MFD it is common to only have a single node in devicetree representing the whole device.

[alsa-devel] Unable to handle kernel paging request in snd_seq_oss_readq_puts
by DaeRyong Jeong 27 Apr '18

27 Apr '18

We report the crash: unable to handle kernel paging request in snd_seq_oss_readq_puts This crash has been found in v4.16 using RaceFuzzer (a modified version of Syzkaller), which we describe more at the end of this report. Our analysis shows that the race occurs when invoking two syscalls concurrently, write$eventfd and write$sndseq. Analysis: We think the concurrent execution of snd_virmidi_output_trigger() and snd_midi_event_encode_byte() causes the crash.

While we leverage many different technique, the notable feature of RaceFuzzer is in leveraging a custom hypervisor (QEMU/KVM) to interleave the scheduling. In particular, we modified the hypervisor to intentionally stall a per-core execution, which is similar to supporting per-core breakpoint functionality. This allows RaceFuzzer to force the kernel to deterministically trigger racy condition (which may rarely happen in practice due to randomness in scheduling). RaceFuzzer's C repro always pinpoints two racy syscalls. Since C repro's scheduling synchronization should be performed at the user space, its reproducibility is limited (reproduction may take from 1 second to 10 minutes (or even more), depending on a bug). This is because, while RaceFuzzer precisely interleaves the scheduling at the kernel's instruction level when finding this bug, C repro cannot fully utilize such a feature. Please disregard all code related to "should_hypercall" in the C repro, as this is only for our debugging purposes using our own hypervisor.

[alsa-devel] rt5645 Jack detect code on an Asus T100HA not being able to distinguish between headphones vs headset ?
by Hans de Goede 27 Apr '18

27 Apr '18

Hi Bard, I'm having some trouble with the rt5645.c codec code not being able to distinguish between headphones vs headset on an Asus T100HA laptop. It recognizes everything as headphones. This statement in the jack-detect code: dev_dbg(component->dev, "val = %d\n", val); Always prints 4 for the value, no matter what I plug in. Also the headset microphone input does not work, not even if I select it manually. The ACPI id for the device is 10EC3270, and I opened the tablet and the marking on the codec says: ALC3270, so I guess we may need some special handling for the jack-detect (and headset microphone input) on this variant, can you help? I checked and the jack connector does seem to be of the TRRS type. Regards, Hans

[alsa-devel] [PATCH] ASoC: dai playback and capture active may be greater than 1
by Jerome Brunet 27 Apr '18

27 Apr '18

At the moment playback_active and capture_active are using only 1 bit so the maximum active count is 1. However, snd_soc_runtime_activate() may be called several time on the same dai. This happens when a dai is part of several dai_links. It is often the case for "snd-soc-dummy-dai". This is a problem if snd_soc_runtime_activate() is called an even number of times on a dai. In this case the active count overflow back to 0. As consequence, ASoC functions, such as soc_dpcm_runtime_update(), won't run correctly. Storing these usage counts on plain 'unsigned int' solves the problem. Fixes: f0fba2ad1b6b ("ASoC: multi-component - ASoC Multi-Component Support") Signed-off-by: Jerome Brunet <jbrunet(a)baylibre.com> --- Hi, I found this problem while working on ASoC support for a new platform. During a playback, using DPCM, if I changed the backend dai, nothing happened, old backend path is not pruned, new backend path is not added. Here is how it goes: 1 FE and 2 BE, all 3 using snd-soc-dummy-dai for the codec_dai (ATM). On playback start: - BE #1 activates and increments snd-soc-dummy-dai's playback_active - FE activates and increments snd-soc-dummy-dai's playback_active The playback works but snd-soc-dummy-dai's playback_active value is now 0. Through a mux kcontrol, change BE client of FE, from BE #1 to BE #2. -> trigger soc_dpcm_runtime_update(). -> checks fe's codec_dai playback_active which is zero so playback path processing is skipped, keeping the old invalid path. * No change since initial RFC [0], just droppped the RFC prefix.

[alsa-devel] [PATCH 0/5] ARM/ASoC: omap: n810 audio support
by Peter Ujfalusi 27 Apr '18

27 Apr '18

Hi, The verification of the sdma-pcm on OMAP2 got delayed by non working audio on n810. With the following patches audio works on n810 (both with the old omap-pcm and the new sdma-pcm). I believe the DTS and ASoC patches are fine to go via different tree, but I wanted to keep the patches together for easier testing. The series does not have any dependencies, I will rebase the sdma-pcm series on top of this and resend.

[alsa-devel] Applied "ASoC: add mt6797-mt6351 driver and config option" to the asoc tree
by Mark Brown 27 Apr '18

27 Apr '18

The patch ASoC: add mt6797-mt6351 driver and config option has been applied to the asoc tree at https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted. You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail.

[alsa-devel] [PATCH 00/11] ALSA: dice: use cache of stream formats to generate PCM rules/constraints
by Takashi Sakamoto 27 Apr '18

27 Apr '18

Hi, Once, ALSA dice driver cached stream formats to generate PCM constraints/rules. The cache is created by changing current sampling transmission frequency step by step directly at unit probing process. This feature was dropped because it changes state of clock on target device thus it's against users' expectation[1]. However this is not necessarily convenient because reconfiguration of sampling rate is not available. TC Applied Technologies (TCAT) has extended protocol for DICE interface, a.k.a EAP (Extended Application Protocol). In this extension, drivers can retrieve information of stream formats without changing state of target unit. Fortunately, this protocol is supported widely by many models. This patchset regain the cache to generate PCM constraints/rules by using this protocol. Userspace applications can reconfigure sampling rate via ALSA PCM interface. For units which doesn't support the extension, available set of sampling rate is still restricted at current sampling transmission frequency. This is also inconvenient and this patchset introduces a solution. Structure for unit entry (struct ieee1394_device_id) has a member for unit-specific data. This patchset uses it for callback function to handle hard-coded stream format. In this time, I adopt this way for some known models produced by TC Electronic and Alesis. If users find their models still have restrictions in a point of available sampling transmission frequency, it's preferable to work for this way.

[alsa-devel] [PATCH 0/8] Fix year 2038 issue for sound subsystem
by Baolin Wang 26 Apr '18

26 Apr '18

Since many structures will use timespec type variables to record time stamp in uapi/asound.h, which are not year 2038 safe on 32bit system. This patchset tries to introduce new structures removing timespec type to compatible native mode and compat mode. Moreover this patchset also converts the internal structrures to use timespec64 type and related APIs.

[alsa-devel] [PATCH 0/4] ALSA: Fix year 2038 issue for sound subsystem, alternative
by Arnd Bergmann 26 Apr '18

26 Apr '18

I've tried the suggestion from Jaroslaw, doing a minimal change to the UAPI headers to keep the existing binary interface. As he predicted, this is a much simpler set of kernel changes, but we will pay for that with added complexity in alsa-lib. The first two patches in this series are taken from Baolin's patch set, with a small bugfix folded in to avoid a compile-time regression. The other two patches are to redefine the UAPI and to deprecate the support for CLOCK_REALTIME time stamps, which we can no longer allow with user space that we expect to survive beyond 2038. Overall, I'd still be happier with Baolin's approach since it allows us to keep compatiblity with CLOCK_REALTIME users and requires fewer changes in user space, but this would work as well.

[alsa-devel] [PATCH 1/3] ASoC: compress: Only call free for components which have been opened
by Charles Keepax 26 Apr '18

26 Apr '18

The core should only call free on a component if said component has already had open called on it. This is not presently the case and most compressed drivers in the kernel assume it will be. This causes null pointer dereferences in the drivers as they attempt clean up for stuff that was never put in place. This is fixed by aborting calling open callbacks once a failure is encountered and then during clean up only iterating through the component list to that point. This is a fairly quick fix to the issue, to allow backporting. There is more refactoring to follow to tidy the code up a little.

The patch ASoC: Remove platform code now everything is componentised has been applied to the asoc tree at https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted. You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail. Thanks, Mark >From ef050bece1b5564b2c7135ceadc0d5ffdcf152f7 Mon Sep 17 00:00:00 2001 From: Charles Keepax <ckeepax(a)opensource.cirrus.com> Date: Tue, 24 Apr 2018 16:39:02 +0100 Subject: [PATCH] ASoC: Remove platform code now everything is componentised As all drivers have been moved over to the new generic component code remove the now unused platform specific code.

[alsa-devel] [PATCH 1/2] ASoC: AMD: Use single dai for da7219 playback and capture
by Akshu Agrawal 26 Apr '18

[alsa-devel] [PATCH v5 00/13] soundwire: Add stream support
by Vinod Koul 26 Apr '18

26 Apr '18

This series adds support in SoundWire subsystem for: - Documentation for stream support - stream management - data port management - DAI ops in cadence and Intel drivers - ASoC API to propagate SDW stream Updated in v5: - Add todo for device-device changes in future and some comment updates based on feedback from Pierre Updates in v4: - Add more comments for sdw_release_master_stream() - Make sure ports are freed upon sdw_stream_remove_slave() - Clarify snd_soc_dai_set_sdw_stream() and setting of NULL upon release. Updates in v3: - Remove stream state transition checks and redefine stream states - Update bansk switch routines - Other nitpicks pointed out by Pierre. Updates in v2: - Make ASoC API inlined - Make stream states as states and not action - Update the direction enum - Fix some typos and comment updates Sanyog Kale (7): Documentation: soundwire: Add more documentation soundwire: Add support for SoundWire stream management soundwire: Add support for port management soundwire: Add Master and Slave port programming soundwire: Add helpers for ports operations soundwire: Add bank switch routine soundwire: Add stream configuration APIs Shreyas NC (2): ASoC: Add SoundWire stream programming interface soundwire: Remove cdns_master_ops Vinod Koul (4): soundwire: cdns: Add port routines soundwire: cdns: Add stream routines soundwire: intel: Add stream initialization soundwire: intel: Add audio DAI ops .../driver-api/soundwire/error_handling.rst | 65 + Documentation/driver-api/soundwire/index.rst | 3 + Documentation/driver-api/soundwire/locking.rst | 106 ++ Documentation/driver-api/soundwire/stream.rst | 372 +++++ drivers/soundwire/Kconfig | 2 +- drivers/soundwire/Makefile | 2 +- drivers/soundwire/bus.c | 43 + drivers/soundwire/bus.h | 72 + drivers/soundwire/cadence_master.c | 453 +++++- drivers/soundwire/cadence_master.h | 151 ++ drivers/soundwire/intel.c | 528 ++++++- drivers/soundwire/intel.h | 4 + drivers/soundwire/intel_init.c | 3 + drivers/soundwire/stream.c | 1490 ++++++++++++++++++++ include/linux/soundwire/sdw.h | 332 ++++- include/linux/soundwire/sdw_intel.h | 14 + include/sound/soc-dai.h | 23 + 17 files changed, 3649 insertions(+), 14 deletions(-) create mode 100644 Documentation/driver-api/soundwire/error_handling.rst create mode 100644 Documentation/driver-api/soundwire/locking.rst create mode 100644 Documentation/driver-api/soundwire/stream.rst create mode 100644 drivers/soundwire/stream.c -- 2.7.4

[alsa-devel] [PATCH][RESEND] ASoC: Intel: atom: fix ACPI/PCI Kconfig
by Pierre-Louis Bossart 25 Apr '18

25 Apr '18

The split between ACPI and PCI platforms generated issues with randconfig: with SND_SST_ATOM_HIFI2_PLATFORM_PCI=y and SND_SST_ATOM_HIFI2_PLATFORM=m, we get this module link failure: ERROR: "sst_context_init" [sound/soc/intel/atom/sst/snd-intel-sst-acpi.ko] undefined! ERROR: "sst_context_cleanup" [sound/soc/intel/atom/sst/snd-intel-sst-acpi.ko] undefined! ERROR: "sst_alloc_drv_context" [sound/soc/intel/atom/sst/snd-intel-sst-acpi.ko] undefined! ERROR: "intel_sst_pm" [sound/soc/intel/atom/sst/snd-intel-sst-acpi.ko] undefined! ERROR: "sst_configure_runtime_pm" [sound/soc/intel/atom/sst/snd-intel-sst-acpi.ko] undefined! To keep things simple, let's expose two configs for SND_SST_ATOM_HIFI2_PLATFORM_PCI and SND_SST_ATOM_HIFI2_PLATFORM_ACPI, which select a common SND_SST_ATOM_HIFI2_PLATFORM option. To avoid breaking existing solutions with the semantics change, SND_SST_ATOM_HIFI2_PLATFORM_ACPI uses "default ACPI" so that "make oldnoconfig" and "make olddefconfig" still work as expected. Also remove mentions of Medfield while we are at it since it was removed recently.
