14 Feb '19

The patch ASoC: samsung: i2s: Drop spinlock pointer from i2s_dai data structure 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 v3 00/13] ASoC: dmaengine updates, secondary CPU DAI for Odroid boards
by Sylwester Nawrocki 14 Feb '19

14 Feb '19

This is a rebased version with the build break fixed and added Krzysztof's Acks. My apologies, I double checked there is no build errors between patches this time. Below is cover letter text from v2. This series restores support for the secondary CPU DAI in samsung/i2s.c driver and adds support for secondary CPU DAI on Odroid boards. I have added 4 more clean up patches comparing to first version of the patch set (16/22...19/22). The first patch adds new platform device for the secondary PCM, I tried to avoid registering new platform device in probe() as it doesn't play well with deferred probing but couldn't find a way to avoid that new device, unique devices are needed to register "PCM" components for each CPU DAI. Patches 2/21...11/21 are mostly a clean up, following conversion to single component with multiple DAIs, allowing to reference both primary/secondary DAI in DT. The patch set has been tested on Odroid U3, XU3, XU4 and Mini2440 (s3c2440 non-DT) boards. Changes since v1 ((addressing Krzysztof's review comments): - added a comment, whitespace change in patch 1/21 - dropped unnecessary new line addition from patch 1/21 Sylwester Nawrocki (13): ASoC: samsung: i2s: Move SFR pointer to common driver data structure ASoC: samsung: i2s: Drop spinlock pointer from i2s_dai data structure ASoC: samsung: i2s: Move IP variant data to common driver data structure ASoC: samsung: i2s: Move quirks data to common driver data structure ASoC: samsung: i2s: Get rid of a static spinlock ASoC: samsung: odroid: Add support for secondary CPU DAI ASoC: samsung: Specify DMA channel names through custom DMA config ASoC: samsung: Drop DAI DMA data chan_name assignments ASoC: dmaengine: Remove unused SND_DMAENGINE_PCM_FLAG_CUSTOM_CHANNEL_NAME flag ASoC: samsung: i2s: Simplify pri_dai, sec_dai pointers usage ASoC: samsung: i2s: Change indentation in SAMSUNG_I2S_FMTS definition ASoC: samsung: i2s: Comments clean up ASoC: samsung: i2s: Convert to SPDX License Indentifier include/sound/dmaengine_pcm.h | 6 - sound/soc/samsung/dmaengine.c | 12 +- sound/soc/samsung/i2s.c | 297 +++++++++++++------------- sound/soc/samsung/odroid.c | 131 ++++++++---- sound/soc/samsung/s3c2412-i2s.c | 4 +- sound/soc/samsung/s3c24xx-i2s.c | 4 +- sound/soc/soc-generic-dmaengine-pcm.c | 21 +- 7 files changed, 250 insertions(+), 225 deletions(-) -- 2.17.1

[alsa-devel] [PATCH 0/2] ASoC: da7219: BCLK and TDM flexibility improvements
by Adam Thomson 14 Feb '19

14 Feb '19

This patch set updates the driver to be more flexible regarding the BCLK and TDM configurations of the device. Previously the BCLK rate was fixed at 64 periods per WCLK, when the codec is DAI clock master, but to satisfy devices which prefer a lower rate, and to save power, the BCLK rate is now calculated based on hw_params() data. As a fallout of the BCLK efforts it was also apparent that the TDM code could be made more flexible as well. The device is capable of automatically detecting the BCLK rate when it is clock slave, so previous limitations imposed were not necessary. The mask handling is now used as an input to determine the BCLK offset to align closer with other examples within ALSA.

[alsa-devel] [PATCH] ALSA: hda/realtek: Disable PC beep in passthrough on alc285
by Hui Wang 14 Feb '19

14 Feb '19

It is reported that there's a constant background "hum/whitenoise" in the headset on the Lenovo X1 machines with the codec alc285, and it is confirmed that if we run the command below, the noise will stop. sudo hda-verb /dev/snd/hwC0D0 0x1d SET_PIN_WIDGET_CONTROL 0x0 Then I consulted this issue with Kailang, he told me the pin 0x1d on this codec is used for PC beep in, the noise probably comes from this pin and we can also disable the PC beep in passthrough, then the PC beep in will not affect other sound playback.

[alsa-devel] right way to enumerate pcm devices
by sylvain.bertrand＠gmail.com 14 Feb '19

14 Feb '19

Hi, I got some code based on hints which, unfortunately, seems not sufficient. I can list the hardware cards, but what is the proper way to enumerate the pcm devices? For instance, I don't get basic user defined pcm devices, I get all the surround pcm devices for the USB mic from my webcam etc... The real question: how I build a clean list of pcm devices I would present to a user to choose from without confusing him/her? Wherever I look I get only this hint based code. I presume I am looking the wrong way. regards, -- Sylvain

[alsa-devel] [PATCH] Headset microphone and internal speaker support for System76 oryp5
by Jeremy Soller 13 Feb '19

13 Feb '19

On the System76 Oryx Pro (oryp5), there is a headset microphone input attached to 0x19 that does not have a jack detect. In order to get it working, the pin configuration needs to be set correctly, and the ALC269_FIXUP_HEADSET_MODE_NO_HP_MIC fixup needs to be applied. This is similar to the MIC_NO_PRESENCE fixups for some Dell laptops, except we have a separate microphone jack that is already configured correctly. Since the ALC1220 does not have a fixup similar to ALC269_FIXUP_HEADSET_MODE_NO_HP_MIC, I have exposed the fixup from the ALC269 in a way that it can be accessed from the alc1220_fixup_system76_oryp5 function. In addition, the alc1220_fixup_clevo_p950 needs to be applied to gain speaker output.

[alsa-devel] Applied "ASoC: samsung: i2s: Move registers cache to common driver data structure" to the asoc tree
by Mark Brown 13 Feb '19

13 Feb '19

The patch ASoC: samsung: i2s: Move registers cache to common driver data structure 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 00/22] ASoC: dmaengine updates, secondary CPU DAI for Odroid boards
by Sylwester Nawrocki 12 Feb '19

12 Feb '19

This series restores support for the secondary CPU DAI in samsung/i2s.c driver and adds support for secondary CPU DAI on Odroid boards. First two patches introduce changes in ASoC generic dmaengine driver so as to use custom DMA config as introduced in commit 194c7dea00c6 "ASoC: dmaengine: add custom DMA config to snd_dmaengine_pcm_config" for handling custom DMA channel names on all Samsung platforms. Patches 7/22...16/22 are mostly clean up, following conversion to single component with multiple DAIs in patch 5/22, allowing to reference both primary/secondary DAI in DT. I tried to avoid registering new platform device in probe() as it doesn't play well with deferred probing but couldn't find a way to avoid that new device, unique devices are needed to register "PCM" components for each CPU DAI. I am not entirely sure we should be removing the SND_DMAENGINE_PCM_FLAG_CUSTOM_CHANNEL_NAME flag like this, it might all be a bit more explicit with the flag. The patch set has been tested on Odroid U3, XU3, XU4 and Mini2440 (s3c2440 non-DT) boards. This series depends on patch "ASoC: samsung: Prevent clk_get_rate() calls in atomic context" Sylwester Nawrocki (22): ASoC: dmaengine: Improve of_node test in dmaengine_pcm_request_chan_of() ASoC: dmaengine: Extend use of chan_names provided in custom DMA config ASoC: samsung: dmaengine: Allow to specify custom DMA device ASoC: samsung: i2s: Fix prescaler setting for the secondary DAI ASoC: samsung: i2s: Convert to single component with multiple DAIs ASoC: samsung: i2s: Restore support for the secondary PCM ASoC: samsung: i2s: Move clk supplier data to common driver data structure ASoC: samsung: i2s: Add widgets and routes for DPCM support ASoC: samsung: i2s: Move core clk to the driver common data structure ASoC: samsung: i2s: Move opclk data to common driver data structure ASoC: samsung: i2s: Move registers cache to common driver data structure ASoC: samsung: i2s: Move SFR pointer to common driver data structure ASoC: samsung: i2s: Drop spinlock pointer from i2s_dai data structure ASoC: samsung: i2s: Move IP variant data to common driver data structure ASoC: samsung: i2s: Move quirks data to common driver data structure ASoC: samsung: i2s: Get rid of a static spinlock ASoC: samsung: odroid: Add support for secondary CPU DAI ASoC: samsung: Specify DMA channel names through custom DMA config ASoC: samsung: Drop DAI DMA data chan_name assignments ASoC: dmaengine: Remove unused SND_DMAENGINE_PCM_FLAG_CUSTOM_CHANNEL_NAME flag ARM: dts: exynos5422-odroidxu3: Add support for secondary DAI ARM: dts: exynos5422-odroidxu4: Add support for secondary DAI .../boot/dts/exynos5422-odroidxu3-audio.dtsi | 6 +- arch/arm/boot/dts/exynos5422-odroidxu4.dts | 4 +- include/sound/dmaengine_pcm.h | 6 - sound/soc/samsung/dma.h | 3 +- sound/soc/samsung/dmaengine.c | 16 +- sound/soc/samsung/i2s.c | 630 ++++++++++-------- sound/soc/samsung/odroid.c | 132 +++- sound/soc/samsung/pcm.c | 2 +- sound/soc/samsung/s3c2412-i2s.c | 4 +- sound/soc/samsung/s3c24xx-i2s.c | 4 +- sound/soc/samsung/spdif.c | 2 +- sound/soc/soc-generic-dmaengine-pcm.c | 13 +- 12 files changed, 489 insertions(+), 333 deletions(-) -- 2.20.1

[alsa-devel] don't pass a NULL struct device to DMA API functions
by Christoph Hellwig 12 Feb '19

12 Feb '19

We still have a few drivers which pass a NULL struct device pointer to DMA API functions, which generally is a bad idea as the API implementations rely on the device not only for ops selection, but also the dma mask and various other attributes. This series contains all easy conversions to pass a struct device, besides that there also is some arch code that needs separate handling, a driver that should not use the DMA API at all, and one that is a complete basket case to be deal with separately.

[alsa-devel] [PATCH 00/17] ASoC: soc-acpi: remove SOF file prefix and unused fields
by Pierre-Louis Bossart 12 Feb '19

12 Feb '19

Remove the hard-coded "intel" for all SOF files. The SOF code now adds a different default path for firmware and topology, both of which can be overridden by kernel module arguments. The intent is to make releases more manageable since for the same platform there will be different releases (e.g. public and public+non-public components). This change should have no impact since pre-production devices with early versions of SOF will be updated with these patches. Also remove fields that have not been used by SOF in a long time, Marie Kondo style. In hindsight no one seems to recall why they were necessary.

[alsa-devel] [PATCH] ASoC: hdac_hdmi: use devm_kzalloc for all structures

Loading/unloading modules exposes issues with memory allocation, which is a mix of devm_kzalloc and manual kzalloc. Move to devm_k routines everywhere to simplify all this.

[alsa-devel] [PATCH 0/2][RFC] ASoC: soc-core: modern style dai_link control
by Kuninori Morimoto 12 Feb '19

12 Feb '19

Hi Mark These are [RFC] patches which adds new rule for modern style dai_link. Many sound are using CPU component as Platform component, and then it has below settings on legacy style dai_link dai_link->platform_of_node = dai_link->cpu_of_node But, this duplicated component will be just ignored because it is already selected when CPU component binding. We want to allow "no Platform" on modern style dai_link. And, current legacy style dai_link allows no Platform settings, then, soc-core will select snd-soc-dummy platform for it automatically. In modern style, we need to have CPU/Codec/Platform as array/pointer style. Thus, this kind of "implicit" selection will be just un-understandable. These 2 patches adds new rule for modern style, and have no effect to legacy style. But, I can't test for *all* board/situation. Thus, I added [RFC] for these.

[alsa-devel] [PATCH] pcm: dshare: Fix overflow when slave_hw_ptr rolls over boundary
by Brendan Shanks 12 Feb '19

12 Feb '19

In snd_pcm_dshare_sync_area() when 'slave_hw_ptr' rolls over 'slave_boundary', the wrong variable is checked ('dshare->slave_hw_ptr' vs the local 'slave_hw_ptr'). In some cases, this results in 'slave_hw_ptr' not rolling over correctly. 'slave_size' and 'size' are then much too large, and the for loop blocks for several minutes copying samples. This was likely only triggered on 32-bit systems, since the PCM boundary is computed based on LONG_MAX and is much larger on 64-bit systems. This same change was made to pcm_dmix in commit 6c7f60f7a982fdba828e4530a9d7aa0aa2b704ae ("Fix boundary overlap”) from June 2005.

[alsa-devel] pcm_dshare calculates size incorrectly on buffer rollover
by Brendan Shanks 11 Feb '19

11 Feb '19

I'm working on an embedded system based on an Ambarella H1 SoC (32-bit ARM Cortex A9). Audio playback through ALSA (and GStreamer) works fine when playing to the raw hw device. When playing through dshare (my normal configuration), playback stops after exactly 7 hours 16 minutes, for about 3 minutes. During the 3 minutes, the playback thread consumes an entire CPU core. After the 3 minutes, GStreamer reports an xrun, recovers from it, and playback goes back to normal. After some debugging, the problem seems to be in snd_pcm_dshare_sync_area(). When dshare->appl_ptr rolls over to 0, 'size' becomes huge, 3036676576. 'slave_size' is also much bigger than it should be, 1258291680. This is what 'size' is set to when the for loop starts, and I believe the for loop then spends ~3 minutes copying a huge amount of samples. This also explains the 7h16m time, it's linked to the PCM boundary which is 1258291200. At 48 kHz, 1258291200 samples takes 7h16m54s. I'm not sure what the fix should be though. Is this really a bug in dshare, or are bad values being set somewhere else? GStreamer? Or maybe the period/buffer size (480/9600) is causing problems? Any advice is appreciated, my modified snd_pcm_dshare_sync_area() and the output are below.

[alsa-devel] [PATCH 1/1] seq: arecordmidi: Add num-events option
by pmalani＠chromium.org 11 Feb '19

11 Feb '19

From: Prashant Malani <pmalani(a)chromium.org> Add a command line option to automatically exit after recording a fixed number of MIDI events. This allows a program using arecordmidi to expect a MIDI file to be written automatically when the specified number of events have been received, instead of having to send a SIGINT or SIGTERM programmatically. It also avoids the need to have the arecordmidi process running in the background, and then constantly stat the output file to check if any bytes have been written to it (this makes for less predictable and longer-running tests). This functionality finds use in Chrome OS functional testing, since having to send SIGTERM/SIGINT programmatically and then wait for the output file adds unpredictability and delay to the tests. The addition of this command-line option should (hopefully) not break any existing usage.

It's a bug since v4.12 or later, indeed. Unfortunately, I'm on vacation. I'll post the patch to fix it in next week after testing it with MOTU models I own. Thanks for your report ;) By the way, I guess that you see many kernel messages with 'unsolicited response' from firewire-core driver, like. fireire_core 0000:03:00.0: unsolicited response (source ffc0, tlabel 1f) As long as I know, AudioExpress often transfers invalid response code for any asynchronous transaction[1]. This brings failures of read/write transaction and ALSA MOTU driver sometimes fails to handle the device. For your information.

[alsa-devel] [PATCH v6 0/3] ALSA: pcm: anonymous dup implementation
by Jaroslav Kysela 08 Feb '19

08 Feb '19

This patchset contains the anonymous dup implementation with permissions checking for the ALSA's PCM interface in kernel to enable the restricted DMA sound buffer sharing for the restricted tasks. The code was tested through qemu and it seems to be pretty stable. The initial tinyalsa implementation can be found here: https://github.com/perexg/tinyalsa/commits/anondup The filtering might be refined. It depends on the real requirements. Perhaps, we may create more ioctl groups. Any comments are more than welcome. v2 of the patches: - change clone parameter to subdevice number for the pcm attach - change SNDRV_PCM_PERM_MAX to SNDRV_PCM_PERM_MASK - the tinyalsa implementation was a little updated (restructured) v3 of the patches: - group integer declarations in snd_pcm_anonymous_dup() - replaced substream->pcm with pcm in snd_pcm_anonymous_dup() - added SNDRV_PCM_PERM_RW check for read/write/readv/writev syscalls v4 of the patches: - more simple restriction control (only two modes - full/buffer) - the tinyalsa implementation follows this change v5 of the patches: - merge pcm_..._mmap_allowed fcns to the snd_pcm_mmap_... fcns v6: - add proper open_mutex protection for snd_pcm_open_file() Cc: Phil Burk <philburk(a)google.com> Cc: Zach Riggle <riggle(a)google.com> Cc: Mark Brown <broonie(a)kernel.org> Cc: Leo Yan <leo.yan(a)linaro.org> Cc: Baolin Wang <baolin.wang(a)linaro.org> Jaroslav Kysela (3): ALSA: pcm: implement the anonymous dup (inode file descriptor) ALSA: pcm: merge pcm_..._mmap_allowed fcns to the snd_pcm_mmap_... fcns ALSA: pcm: implement the mmap buffer mode for the anonymous dup include/sound/pcm.h | 10 +-- include/uapi/sound/asound.h | 6 +- sound/core/oss/pcm_oss.c | 2 +- sound/core/pcm.c | 13 ++-- sound/core/pcm_compat.c | 1 + sound/core/pcm_native.c | 154 +++++++++++++++++++++++++++++++++----------- 6 files changed, 133 insertions(+), 53 deletions(-) -- 2.13.6

[alsa-devel] [PATCH RFC/untested] hda-intel: suspend HDA codecs and the PCI device in error cases
by Guennadi Liakhovetski 08 Feb '19

08 Feb '19

From: Guennadi Liakhovetski <guennadi.liakhovetski(a)linux.intel.com> If HDA probing on Intel platforms fails, all the devices, that have previously been powered up, have to be suspended again. Signed-off-by: Guennadi Liakhovetski <guennadi.liakhovetski(a)linux.intel.com> --- I came across HDA not suspending when no codec driver has successfully probed while working on SOF. Then I decided to look how this is handled in the mainline Intel HDA code and I think something like this patch is needed, however, I don't have a set up to test it.

[alsa-devel] Async ops SOC compress issue
by b_lkasam＠codeaurora.org 08 Feb '19

Hi ALSA team, Need inputs wrt one issue seen with soc-compress code. Please help check below issue seen in soc-compress file wrt handling multiple BEs with async ops ASYNC_DPCM_SND_SOC_HW_PARAMS set for given FE dailink/BE dailinks also. Issue : pcm_prepare failure when 2 BE's on same FE enabled during compress playback, seen only when both BE's have SOC_HW_PARAM defined as an async_op. Analysis: - With SOC_HW_PARAMS defined as async_op on both BE's, hw_params api for both of these BE's are scheduled for asynchronous execution. - It is observed that dpcm_be_hw_params_prepare is getting invoked twice, but for the same BE.

[alsa-devel] [PATCH] ASoC: samsung: Prevent clk_get_rate() calls in atomic context
by Sylwester Nawrocki 07 Feb '19

07 Feb '19

This patch moves clk_get_rate() call from trigger() to hw_params() callback to avoid calling sleeping clk API from atomic context and prevent deadlock as indicated below.

Where possible, it uses SOC_DAPM_DOUBLE in order to cut down on the number of distinct controls in alsamixer. v15 changes compared to v14 are: - Instead of adding controls dynamically, add an extra sun7i_codec_controls structure and duplicate the sun4i_codec_controls there, with small changes. - Split Mic Playback Volume into extra patch. - LEFT OFF adding Capture Selects since it's unclear how we want to structure it. - LEFT OFF adding Differential Line Source since it might also change if the Capture Select implementation is different. 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] [PATCH] ALSA: pcm: Revert capture stream behavior change in blocking mode
by Takashi Iwai 07 Feb '19

07 Feb '19

In the commit 62ba568f7aef ("ALSA: pcm: Return 0 when size < start_threshold in capture"), we changed the behavior of __snd_pcm_lib_xfer() to return immediately with 0 when a capture stream has a high start_threshold. This was intended to be a correction of the behavior consistency and looked harmless, but this was the culprit of the recent breakage reported by syzkaller, which was fixed by the commit e190161f96b8 ("ALSA: pcm: Fix tight loop of OSS capture stream"). At the time for the OSS fix, I didn't touch the behavior for ALSA native API, as assuming that this behavior actually is good. But this turned out to be also broken actually for a similar deployment, e.g. one thread goes to a write loop in blocking mode while another thread controls the start/stop of the stream manually. Overall, the original commit is harmful, and it brings less merit to keep that behavior. Let's revert it.

[alsa-devel] [PATCH] UCM: bytcr/PlatformEnableSeq.conf update some comments
by Hans de Goede 07 Feb '19

07 Feb '19

Commit f91cc3c7d6b7 ("Update chtrt5645 ucm variants to use bytcr/PlatformEnableSeq.conf component") updated the following 2 comments: # codec0_out settings (used if SSP2 is connected to aif1) # modem_out settings (used if SSP0 is connected to aif2) Specifically it added the " to aif1" resp. " to aif2" part of the comments. This is not correct, AIF1 / AIF2 are something which is present on Realtek codecs only, and either one can be used indepedent of SSP0 or SSP2 being used (the comments in the chtrt5645 UCM profile before this change were wrong / outdated). Besides there not being any relationship between SSP0 or SSP2 being used, bytcr/PlatformEnableSeq.conf is also used with other codecs, e.g. the ESS8316 codec where this is not applicable at all. Therefor this commit removes the " to aif?" part of the comments again to avoid confusing people reading this in the future.

The patch ASoC: dapm: fix out-of-bounds accesses to DAPM lookup tables 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.

The patch ASoC: dapm: Check for NULL widget in dapm_update_dai_unlocked 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.

If the digital core is activated too early, or even before the ADC is powered up, audible artifacts appear at the beginning of the recorded signal. The digital core is also needed for playback, so when recording starts it may already be enabled. This means we cannot get the power sequence correct when we want to be able to start recording after playback. As a workaround put the MIC mute switch into the DAPM routes. This way we can keep the recording disabled until the MIC Bias has settled and thus get rid of audible artifacts.

[alsa-devel] [PATCH 1/2] ASoC: compress: Clarify the intent of current compressed ops handling
by Charles Keepax 06 Feb '19

06 Feb '19

For callbacks configuring the state of the components (trigger, set_params, ack and set_metadata) simplify the code a little and make intention clearer by aborting as soon as an error is encountered. The operation has already failed and there is nothing to be gained from processing the callbacks on additional components. The operations currently abort after the callbacks, so this simply shortens the error path. For callbacks returning information from the driver (copy, get_metadata, pointer, get_codec_caps, get_caps and get_params) only look for the first callback provided, currently the code will call every callback only returning the information provided by the last. Since we can only return one set of data, it makes no sense to request the data from every component. Again this just makes the currently supported feature set a little more clear.

[alsa-devel] [PATCH 00/20] ALSA: Drop superfluous PCM preallocation error checks
by Takashi Iwai 06 Feb '19

06 Feb '19

Hi, this is yet another patchset for trivial cleanups. At this time, it's about the superfluous error check from snd_pcm_lib_preallocate_pages() and co. They always succeed and never return a failure although many codes do the error check. The patches simply remove the error checks and finally change the function to be void function. The patches are applied on top of my previous NULL device fix patches, so not applicable to ASoC tree, I guess. As all these are trivial, applying through my tree altogether would be simpler. So, Mark, please give your ACK if the changes to ASoC drivers are OK. thanks, Takashi === Takashi Iwai (20): ALSA: atmel: Drop superfluous PCM preallocation error checks ALSA: parisc: Drop superfluous PCM preallocation error checks ALSA: pci: Drop superfluous PCM preallocation error checks ALSA: ppc: Drop superfluous PCM preallocation error checks ALSA: sh: Drop superfluous PCM preallocation error checks ALSA: sparc: Drop superfluous PCM preallocation error checks ALSA: spi: Drop superfluous PCM preallocation error checks ALSA: usb: Drop superfluous PCM preallocation error checks ASoC: amd: Drop superfluous PCM preallocation error checks ASoC: dwc: Drop superfluous PCM preallocation error checks ASoC: intel: Drop superfluous PCM preallocation error checks ASoC: mediatek: Drop superfluous PCM preallocation error checks ASoC: meson: Drop superfluous PCM preallocation error checks ASoC: sh: Drop superfluous PCM preallocation error checks ASoC: stm: Drop superfluous PCM preallocation error checks ASoC: txx9: Drop superfluous PCM preallocation error checks ASoC: uniphier: Drop superfluous PCM preallocation error checks ASoC: xtensa: Drop superfluous PCM preallocation error checks ASoC: dmaengine: Drop superfluous PCM preallocation error checks ALSA: pcm: Define snd_pcm_lib_preallocate_*() as returning void include/sound/pcm.h | 8 ++--- sound/atmel/ac97c.c | 4 +-- sound/core/pcm_memory.c | 29 +++++----------- sound/parisc/harmony.c | 10 ++---- sound/pci/ad1889.c | 7 +--- sound/pci/aw2/aw2-alsa.c | 40 +++++++--------------- sound/pci/bt87x.c | 10 +++--- sound/pci/ca0106/ca0106_main.c | 16 ++++----- sound/pci/echoaudio/echoaudio.c | 16 ++++----- sound/pci/emu10k1/emupcm.c | 22 ++++++++---- sound/pci/emu10k1/p16v.c | 17 ++++----- sound/pci/lx6464es/lx6464es.c | 8 ++--- sound/pci/rme9652/hdspm.c | 20 +++-------- sound/pci/via82xx_modem.c | 8 ++--- sound/ppc/snd_ps3.c | 6 +--- sound/sh/aica.c | 14 ++++---- sound/soc/amd/acp-pcm-dma.c | 26 ++++++-------- sound/soc/amd/raven/acp3x-pcm-dma.c | 9 +++-- sound/soc/dwc/dwc-pcm.c | 3 +- sound/soc/intel/atom/sst-mfld-platform-pcm.c | 9 ++--- sound/soc/intel/baytrail/sst-baytrail-pcm.c | 15 +++----- sound/soc/intel/haswell/sst-haswell-pcm.c | 10 ++---- sound/soc/intel/skylake/skl-pcm.c | 9 ++--- .../soc/mediatek/common/mtk-afe-platform-driver.c | 6 ++-- sound/soc/meson/axg-fifo.c | 7 ++-- sound/soc/sh/fsi.c | 3 +- sound/soc/sh/rcar/core.c | 5 +-- sound/soc/sh/siu_pcm.c | 13 +------ sound/soc/soc-generic-dmaengine-pcm.c | 5 +-- sound/soc/stm/stm32_adfsdm.c | 5 +-- sound/soc/txx9/txx9aclc.c | 4 ++- sound/soc/uniphier/aio-dma.c | 3 +- sound/soc/xtensa/xtfpga-i2s.c | 6 ++-- sound/sparc/dbri.c | 9 ++--- sound/spi/at73c213.c | 2 +- sound/usb/usx2y/usbusx2yaudio.c | 21 ++++++------ sound/usb/usx2y/usx2yhwdeppcm.c | 19 +++++----- 37 files changed, 157 insertions(+), 267 deletions(-) -- 2.16.4

[alsa-devel] [PATCH v10 0/4] Media Device Allocator API
by Shuah Khan 06 Feb '19

06 Feb '19

Media Device Allocator API to allows multiple drivers share a media device. This API solves a very common use-case for media devices where one physical device (an USB stick) provides both audio and video. When such media device exposes a standard USB Audio class, a proprietary Video class, two or more independent drivers will share a single physical USB bridge. In such cases, it is necessary to coordinate access to the shared resource. Using this API, drivers can allocate a media device with the shared struct device as the key. Once the media device is allocated by a driver, other drivers can get a reference to it. The media device is released when all the references are released. - This patch series is tested on 5.0-rc3 and addresses comments on v9 series from Hans Verkuil. - v9 was tested on 4.20-rc6. - Tested sharing resources with kaffeine, vlc, xawtv, tvtime, and arecord. When analog is streaming, digital and audio user-space applications detect that the tuner is busy and exit. When digital is streaming, analog and audio applications detect that the tuner is busy and exit. When arecord is owns the tuner, digital and analog detect that the tuner is busy and exit. - Tested media device allocator API with bind/unbind testing on snd-usb-audio and au0828 drivers to make sure /dev/mediaX is released only when the last driver is unbound. - Addressed review comments from Hans on the RFC v8 (rebased on 4.19) - Updated change log to describe the use-case more clearly. - No changes to 0001,0002 code since the v7 referenced below. - 0003 is a new patch to enable ALSA defines that have been disabled for kernel between 4.9 and 4.19. - Minor merge conflict resolution in 0004. - Added SPDX to new files. Changes since v9: - Patch 1: Fix mutex assert warning from find_module() calls. This code was written before the change to find_module() that requires callers to hold module_mutex. I missed this during my testing on 4.20-rc6. Hans Verkuil reported the problem. - Patch 4: sound/usb: Initializes all the entities it can before registering the device based on comments from Hans Verkuil - Carried Reviewed-by tag from Takashi Iwai for the sound from v9. - No changes to Patches 2 and 3.

[alsa-devel] [PATCH] ALSA: hda/ca0132 - Fix build error without CONFIG_PCI
by Takashi Iwai 06 Feb '19

06 Feb '19

A call of pci_iounmap() call without CONFIG_PCI leads to a build error on some architectures. We tried to address this and add a check of IS_ENABLED(CONFIG_PCI), but this still doesn't seem enough for sh. Ideally we should fix it globally, it's really a corner case, so let's paper over it with a simpler ifdef.

[alsa-devel] [PATCH] ALSA: compress: Fix stop handling on compressed capture streams
by Charles Keepax 05 Feb '19

05 Feb '19

It is normal user behaviour to start, stop, then start a stream again without closing it. Currently this works for compressed playback streams but not capture ones. The states on a compressed capture stream go directly from OPEN to PREPARED, unlike a playback stream which moves to SETUP and waits for a write of data before moving to PREPARED. Currently however, when a stop is sent the state is set to SETUP for both types of streams. This leaves a capture stream in the situation where a new start can't be sent as that requires the state to be PREPARED and a new set_params can't be sent as that requires the state to be OPEN. The only option being to close the stream, and then reopen. Correct this issues by allowing snd_compr_drain_notify to set the state depending on the stream direction, as we already do in set_params.

[alsa-devel] quirks patch for new T+A USB DAC
by Udo Eberhardt 05 Feb '19

05 Feb '19

Hi all, This is a patch for sound/usb/quirks.c which enables DSD support for a new T+A DAC for which we have developed the USB firmware. Here is a patch description: This patch adds the T+A VID to the generic check in order to enable native DSD support for T+A devices. This works with the new T+A USB DAC model SD3100HV and will also work with future devices which support the XMOS/Thesycon style DSD format. I hope you can apply this patch. Let me know if you need more info. Thank you, Udo

Hi, this is a patchset for cleaning up the procfs handling.

[alsa-devel] [PATCH v2] ALSA: hda/tegra: enable clock during probe
by Sameer Pujar 05 Feb '19

05 Feb '19

From: Kuninori Morimoto <kuninori.morimoto.gx(a)renesas.com> commit 4d230d1271064 ("ASoC: rsnd: fixup not to call clk_get/set under non-atomic") added new rsnd_ssi_prepare() and moved rsnd_ssi_master_clk_start() to .prepare. But, ssi user count (= ssi->usrcnt) is incremented at .init (= rsnd_ssi_init()). Because of these timing exchange, ssi->usrcnt check at rsnd_ssi_master_clk_start() should be adjusted.

[alsa-devel] [PATCH 0/3 v5] ALSA: pcm: anonymous dup implementation
by Jaroslav Kysela 04 Feb '19

04 Feb '19

This patchset contains the anonymous dup implementation with permissions checking for the ALSA's PCM interface in kernel to enable the restricted DMA sound buffer sharing for the restricted tasks. The code was tested through qemu and it seems to be pretty stable.

[alsa-devel] [PATCH v2] ASoC: topology: unload physical dai link in remove
by Pierre-Louis Bossart 04 Feb '19

04 Feb '19

From: Bard liao <yung-chuan.liao(a)linux.intel.com> soc_tplg_link_config() will find the physical dai link and call soc_tplg_dai_link_load() to load the BE dai link. Currently remove_link() is only used to remove the FE dai link which is created by the topology. The BE dai link cannot however be unloaded in snd_soc_tplg_component _remove(), which is problematic if anything needs to be released or reinitialized. This patch aligns the definitions of dynamic types with the existing UAPI and adds a new remove_backend_link() routine to unload the the BE dai link when snd_soc_tplg_component_remove() is invoked.

[alsa-devel] [PATCH] ASoC: soc-core: clear platform pointers on error
by Curtis Malainey 04 Feb '19

04 Feb '19

Originally snd_soc_init_platform was not cleaning up its pointers, this was fixed to always reallocate dynamic memory but created a memory leak when snd_soc_init_platform was called multiple times during the same probe attempt and also threw away any changes made to the struct between calls. In order to avoid reallocating memory that is still valid, the behaviour will be changed to clear the dynamically set pointers on a probe error and a unregister event and snd_soc_init_platform will go back to its original behaviour of only allocating null pointers so it will stop throwing away valid changes.

[alsa-devel] [PATCH] ASoC: rsnd: fixup MIX kctrl registration
by Kuninori Morimoto 02 Feb '19

02 Feb '19

From: Kuninori Morimoto <kuninori.morimoto.gx(a)renesas.com> Renesas sound device has many IPs and many situations. If platform/board uses MIXer, situation will be more complex. To avoid duplicate DVC kctrl registration when MIXer was used, it had original flags. But it was issue when sound card was re-binded, because no one can't cleanup this flags then. To solve this issue, commit 9c698e8481a15237a ("ASoC: rsnd: tidyup registering method for rsnd_kctrl_new()") checks registered card->controls, because if card was re-binded, these were cleanuped automatically. This patch could solve re-binding issue. But, it start to avoid MIX kctrl. To solve these issues, we need below. To avoid card re-binding issue: check registered card->controls To avoid duplicate DVC registration: check registered rsnd_kctrl_cfg To allow multiple MIX registration: check registered rsnd_kctrl_cfg This patch do it.

[alsa-devel] [PATCH 1/2] ASoC: dapm: Only power up active channels from a DAI
by Charles Keepax 02 Feb '19

02 Feb '19

Currently all widgets attached to a DAI link will be powered up when the DAI is active, however this may include routes that are not actually in use if there are unused channels available on the DAI. The macros for creating AIF widgets already include an entry for slot, it is proposed to change that to channel. The effective difference here being respresenting the logical channel index rather than the physical slot index. The CODECs currently using the slot entry on the DAPM_AIF macros are using it in a manner consistent with this, the CODECs not using it just have the field set to zero. A variable is added to snd_soc_dapm_widget to represent this channel index and then for each AIF widget attached to a DAI this is compared against the number of channels on the stream. Enabling the links for those which will be in use. This has the nice property that the CODECs which haven't used the slot/channel entry in the macro will function exactly as before due to all the AIF widgets having a channel of zero and a stream by definition having at least one channel.

[alsa-devel] Applied "ASoC: mediatek: add btcvsd driver" to the asoc tree
by Mark Brown 02 Feb '19

02 Feb '19

The patch ASoC: mediatek: add btcvsd 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.

[alsa-devel] [PATCH] ASoC: dapm: Add warnings for widget overwrite when adding route
by Zhiwei Jiang 02 Feb '19

02 Feb '19

Currently, in some complex cases, more than one widgets have same name and registed from differnt dapm context, and route add from another context too. When snd_soc_dapm_add_route, the previous registered widget will overwritten by the latest same name widget, will cause unexpect error. For Asoc framework we cant avoid this situation and we cant decide which widget that wanted with route. At least we can give users a notice.

[alsa-devel] [PATCH 0/2] ALSA: pcm: implement the anonymous dup v3
by Jaroslav Kysela 01 Feb '19

01 Feb '19

This patchset contains the anonymous dup implementation with permissions checking for the ALSA's PCM interface in kernel to enable the restricted DMA sound buffer sharing for the restricted tasks. The code was tested through qemu and it seems to be pretty stable.

[alsa-devel] [PATCH 0/7] ASoC: topology: fixes and improvements
by Pierre-Louis Bossart 01 Feb '19

01 Feb '19

Module load/unload tests exposed a set of weaknesses in both the SOF and Skylake drivers, some of which are related to the topology framework. This patchset provides a combined set of fixes identified by the two teams. DAPM routes were also not properly handled, leading to confusing issues when the topology resources were released. All these patches were tested on top of the SOF tree, which tracks Mark's branch on a weekly basis.

[alsa-devel] [PATCH] ALSA: hda - Serialize codec registrations
by Takashi Iwai 01 Feb '19

01 Feb '19

In the current code, the codec registration may happen both at the codec bind time and the end of the controller probe time. In a rare occasion, they race with each other, leading to Oops due to the still uninitialized card device. This patch introduces a simple flag to prevent the codec registration at the codec bind time as long as the controller probe is going on. The controller probe invokes snd_card_register() that does the whole registration task, and we don't need to register each piece beforehand.

Right? After checking the whole code, I think what we can do now even safely is to clean up a patch like below. This will reduce lots of code.

For example: alc225_init() alc225_shutup() alc256_init() alc256_shutup() Early patch file hint auto_mute = no equal spec->suppress_auto_mute = 1 It will return function check_auto_mute_availability() in had_generic.c. hp_pin = spec->gen.autocfg.hp_pins[0]; ==> It will get value 0. I think this issue was for a long time. Please see the attach dmesg. One is kill hint auto_mute option. BR, Kailang

[alsa-devel] [PATCH v3 00/14] Sound Open Firmware (SOF) core
by Pierre-Louis Bossart 30 Jan '19

30 Jan '19

Sound Open Firmware (SOF) is a host and DSP architecture agnostic audio DSP firmware. SOF is not tied to any specific host architecture or any specific physical IO communication type (it will work with on SoC DSPs, or DSP connected via SPI/I2C). SOF is also not coupled to any particular DSP architecture and has abstraction similar to Linux to allow porting to other DSP architectures. https://www.sofproject.org/ This patch series introduces the SOF core and utilities. Support for Intel devices is provided as a follow-up series. The SOF core manages all the core DSP services and ALSA/ASoC IO. The core is responsible for loading firmware, parsing topology, exposing PCMs and kcontrols, providing debug and trace mechanisms and performing IPC between host and DSP. The SOF core also has logic to allow reuse of existing machine drivers for other platforms/machines without any code modification. i.e. DAI links can be modified at runtime to bind with SOF and SOF topologies instead of existing hard coded DAI links and topology. Main changes since v2 (end of August): There are honestly too many changes to be listed... The biggest changes are the introduction of an ABI check and runtime_pm, as well as countless improvements coming from product validation. We will provide a revision history starting with the next update. Precisions: Since I've been maintaining the SOF kernel parts for most of 2018, Liam and I mutually agreed that it would be more efficient for me to send the patches upstream to avoid any disconnects. The code in this patchset is directly squashed from the SOF development branch [1], which tracks Mark Brown's for-next branch on a weekly basis and the configurations used for testing are based on the defconfigs at [2] Full disclosure on known limitation and issues (full list at [3]) a) the interaction with ASoC is not always perfect, there are a couple of points where a better solution is desired (use of private data, support for link DMA, etc). The known points are explicitly documented in the code and will be updated. To be clearer, it's our belief that SOF does not cripple ASoC in any way, and that merging this SOF core does not harm others. It's just complicated to get things right, especially on a couple of cases where the topology and DPCM frameworks generate complex flows that very few people understand. b) The get/put methods for controls generate an IPC and possibly a wake-up. This is not optimal and is being fixed. c) The debugfs parts will be updated for runtime_pm parts d) The topology free, firmware release and Hdaudio exit sequences will be updated. It is our intention to fully support module load/unload and free all resources. e) runtime_pm is being hardened and the use of SMART_SUSPEND was suggested. Thank you for reviews and comments, we appreciate the time spent commenting on this large patchset. Thanks in particular to Alan Cox and Andy Shevchenko for their comments on an earlier version.

[alsa-devel] [PATCH 1/2] ASoC: pcm512x: Implement the set_bclk_ratio interface
by Dimitris Papavasiliou 30 Jan '19

30 Jan '19

Some boards, such as the HiFiBerry DAC+ Pro, use a pair of external oscillators, to generate 44.1 or 48kHz multiples and are forced to resort to hacks [1] in order to support 24-bit data without ending up with fractional dividers. This patch allows the machine driver to use 32-bit frames for 24-bit data to avoid such issues. Although the datasheet (p. 15) seems to suggest that only a handful of ratios are supported, it's not very explicit about it, so we allow the full range of values supported by the underlying register in the callback, to avoid needlessly rejecting potentially usable configurations.

It has been split in two, in order to separate the set_bclk_ratio implementation from the clocking calculation fix and some conservative checking has been added to the argument of the callback.

[alsa-devel] [PATCH] ALSA: hda/tegra: enable clock during probe
by Sameer Pujar 30 Jan '19

If CONFIG_PM is disabled or runtime PM calls are forbidden, the clocks will not be ON. This could cause issue during probe, where hda init setup is done. This patch checks whether runtime PM is enabled or not. If disabled, clocks are enabled in probe() and disabled in remove() This patch does following minor changes as cleanup, * return code check for pm_runtime_get_sync() to take care of failure and exit gracefully. * In remove path runtime PM is disabled before calling snd_card_free(). * hda_tegra_disable_clocks() is moved out of CONFIG_PM_SLEEP check. * runtime PM callbacks moved out of CONFIG_PM check Signed-off-by: Sameer Pujar <spujar(a)nvidia.com> Reviewed-by: Ravindra Lokhande <rlokhande(a)nvidia.com> Reviewed-by: Jon Hunter <jonathanh(a)nvidia.com> --- sound/pci/hda/hda_tegra.c | 31 ++++++++++++++++++++++--------- 1 file changed, 22 insertions(+), 9 deletions(-) diff --git a/sound/pci/hda/hda_tegra.c b/sound/pci/hda/hda_tegra.c index c8d18dc..155c2f5 100644 --- a/sound/pci/hda/hda_tegra.c +++ b/sound/pci/hda/hda_tegra.c @@ -219,7 +219,6 @@ static int hda_tegra_enable_clocks(struct hda_tegra *data) return rc; } -#ifdef CONFIG_PM_SLEEP static void hda_tegra_disable_clocks(struct hda_tegra *data) { clk_disable_unprepare(data->hda2hdmi_clk); @@ -227,6 +226,7 @@ static void hda_tegra_disable_clocks(struct hda_tegra *data) clk_disable_unprepare(data->hda_clk); } +#ifdef CONFIG_PM_SLEEP /* * power management */ @@ -257,7 +257,6 @@ static int hda_tegra_resume(struct device *dev) } #endif /* CONFIG_PM_SLEEP */ -#ifdef CONFIG_PM static int hda_tegra_runtime_suspend(struct device *dev) { struct snd_card *card = dev_get_drvdata(dev); @@ -283,7 +282,7 @@ static int hda_tegra_runtime_resume(struct device *dev) int rc; rc = hda_tegra_enable_clocks(hda); - if (rc != 0) + if (rc) return rc; if (chip && chip->running) { hda_tegra_init(hda); @@ -292,7 +291,6 @@ static int hda_tegra_runtime_resume(struct device *dev) return 0; } -#endif /* CONFIG_PM */ static const struct dev_pm_ops hda_tegra_pm = { SET_SYSTEM_SLEEP_PM_OPS(hda_tegra_suspend, hda_tegra_resume) @@ -555,6 +553,13 @@ static int hda_tegra_probe(struct platform_device *pdev) if (!azx_has_pm_runtime(chip)) pm_runtime_forbid(hda->dev); + /* explicit resume if runtime PM is disabled */ + if (!pm_runtime_enabled(hda->dev)) { + err = hda_tegra_runtime_resume(hda->dev); + if (err) + goto out_free; + } + schedule_work(&hda->probe_work); return 0; @@ -571,7 +576,14 @@ static void hda_tegra_probe_work(struct work_struct *work) struct platform_device *pdev = to_platform_device(hda->dev); int err; - pm_runtime_get_sync(hda->dev); + err = pm_runtime_get_sync(hda->dev); + if (err < 0) { + dev_err(hda->dev, + "failed in pm_runtime_get_syc with err = %d\n", + err); + return; + } + err = hda_tegra_first_init(chip, pdev); if (err < 0) goto out_free; @@ -599,12 +611,13 @@ static void hda_tegra_probe_work(struct work_struct *work) static int hda_tegra_remove(struct platform_device *pdev) { - int ret; - - ret = snd_card_free(dev_get_drvdata(&pdev->dev)); pm_runtime_disable(&pdev->dev); + if (!pm_runtime_status_suspended(&pdev->dev)) { + hda_tegra_runtime_suspend(&pdev->dev); + pm_runtime_set_suspended(&pdev->dev); + } - return ret; + return snd_card_free(dev_get_drvdata(&pdev->dev)); } static void hda_tegra_shutdown(struct platform_device *pdev) -- 2.7.4

[alsa-devel] [PATCH] ASoC: rsnd: fixup rsnd_ssi_master_clk_start() user count check
by Kuninori Morimoto 30 Jan '19

30 Jan '19

From: Kuninori Morimoto <kuninori.morimoto.gx(a)renesas.com> commit 4d230d1271064 ("ASoC: rsnd: fixup not to call clk_get/set under non-atomic") added new rsnd_ssi_prepare() and moved rsnd_ssi_master_clk_start() to .prepare. But, ssi user count (= ssi->usrcnt) is incremented at .init (= rsnd_ssi_init()). Because of these timing exchange, ssi->usrcnt check at rsnd_ssi_master_clk_start() should be adjusted. Otherwise, 2nd master clock setup will be no check. This patch fixup this issue.

[alsa-devel] [PATCH] ALSA: hda - Use standard device registration for beep
by Takashi Iwai 29 Jan '19

29 Jan '19

Currently the registration and free of beep input device was done manually from the register and the disconnect callbacks of the assigned codec object. This seems working in most cases, but this may be a cause of some races at probe. Moreover, due to these manual calls, the total code became unnecessarily lengthy. This patch rewrites the beep registration code to follow the standard sound device object style. This allows us reducing the code, in addition to avoiding the nested device registration calls.

DB820c board is based of MSM8996 Qualcomm SoC, which has support for both Digital and Analog audio. Digital audio is over HDMI and analog is over WCD9335 codec via SLIMbus. Board itself has HDMI port, a 3.5mm audio Jack and an Audio expansion connector. This patch adds support for HDMI port and 3.5mm jack.

[alsa-devel] [PATCH 00/14] ALSA: PCM suspend cleanup
by Takashi Iwai 28 Jan '19

Hi, this is a patch set to clean up the PCM suspend calls by introducing the PCM device PM ops. This won't change much for ASoC but reduce lots of snd_pcm_suspend*() calls in other sound drivers. Note that this patch series itself won't fix anything about the recent PM issue reported for Intel ASoC, but it was inspired through the discussion there. thanks, Takashi === Takashi Iwai (14): ALSA: pcm: Suspend streams globally via device type PM ops ALSA: atiixp: Move PCM suspend/resume code into trigger callback ALSA: isa: Remove superfluous snd_pcm_suspend*() calls ALSA: drivers: Remove superfluous snd_pcm_suspend*() calls ALSA: pci: Remove superfluous snd_pcm_suspend*() calls ALSA: usb: Remove superfluous snd_pcm_suspend*() calls ALSA: x86: Remove superfluous snd_pcm_suspend*() calls ALSA: ppc: Remove superfluous snd_pcm_suspend*() calls ALSA: aoa: Remove superfluous snd_pcm_suspend*() calls ALSA: arm: Remove superfluous snd_pcm_suspend*() calls ALSA: pcmcia: Remove superfluous snd_pcm_suspend*() calls drm: bridge: dw-hdmi: Remove superfluous snd_pcm_suspend*() calls ALSA: doc: Update the description about PCM suspend procedure ALSA: pcm: Make snd_pcm_suspend() local static .../kernel-api/writing-an-alsa-driver.rst | 25 ++++++------------ .../drm/bridge/synopsys/dw-hdmi-ahb-audio.c | 1 - include/sound/pcm.h | 6 +---- sound/aoa/soundbus/i2sbus/core.c | 4 --- sound/arm/aaci.c | 1 - sound/arm/pxa2xx-ac97.c | 1 - sound/core/pcm.c | 26 +++++++++++++++++++ sound/core/pcm_native.c | 11 +++----- sound/drivers/aloop.c | 4 --- sound/drivers/dummy.c | 2 -- sound/drivers/pcsp/pcsp.c | 1 - sound/drivers/vx/vx_core.c | 4 --- sound/isa/ad1816a/ad1816a_lib.c | 1 - sound/isa/als100.c | 1 - sound/isa/cmi8328.c | 1 - sound/isa/cmi8330.c | 1 - sound/isa/es1688/es1688.c | 2 -- sound/isa/es18xx.c | 2 -- sound/isa/sb/jazz16.c | 1 - sound/isa/sb/sb16.c | 1 - sound/isa/sb/sb8.c | 1 - sound/isa/wss/wss_lib.c | 1 - sound/pci/ali5451/ali5451.c | 4 +-- sound/pci/als300.c | 1 - sound/pci/als4000.c | 1 - sound/pci/atiixp.c | 19 ++++++-------- sound/pci/atiixp_modem.c | 2 -- sound/pci/azt3328.c | 4 --- sound/pci/ca0106/ca0106_main.c | 3 --- sound/pci/cmipci.c | 4 --- sound/pci/cs4281.c | 2 -- sound/pci/cs46xx/cs46xx_lib.c | 6 ----- sound/pci/cs5535audio/cs5535audio_pm.c | 1 - sound/pci/ctxfi/ctatc.c | 8 ------ sound/pci/echoaudio/echoaudio.c | 3 --- sound/pci/emu10k1/emu10k1.c | 6 ----- sound/pci/ens1370.c | 3 --- sound/pci/es1938.c | 1 - sound/pci/es1968.c | 1 - sound/pci/fm801.c | 1 - sound/pci/hda/hda_codec.c | 2 -- sound/pci/ice1712/ice1712.c | 3 --- sound/pci/ice1712/ice1724.c | 3 --- sound/pci/intel8x0.c | 2 -- sound/pci/intel8x0m.c | 3 --- sound/pci/maestro3.c | 1 - sound/pci/nm256/nm256.c | 1 - sound/pci/oxygen/oxygen_lib.c | 5 +--- sound/pci/riptide/riptide.c | 1 - sound/pci/rme96.c | 2 -- sound/pci/sis7019.c | 1 - sound/pci/trident/trident_main.c | 4 --- sound/pci/via82xx.c | 2 -- sound/pci/via82xx_modem.c | 2 -- sound/pci/ymfpci/ymfpci_main.c | 4 --- sound/pcmcia/pdaudiocf/pdaudiocf_core.c | 1 - sound/ppc/pmac.c | 1 - sound/soc/soc-pcm.c | 1 + sound/usb/card.c | 1 - sound/usb/line6/driver.c | 4 +-- sound/x86/intel_hdmi_audio.c | 12 --------- 61 files changed, 50 insertions(+), 174 deletions(-) -- 2.20.1

[alsa-devel] [PATCH 00/15] ASoC: Intel: pass platform name to machine drivers
by Pierre-Louis Bossart 28 Jan '19

28 Jan '19

To reuse the same machine drivers with Atom/SST, Skylake and SOF, we need to change the default platform_name (or platforms->name in the "modern" representation). So far, this override was done with an automatic override, which was broken by a set of changes for DT platforms related to deferred probe handling. This automatic override is actually not really needed, the machine driver can already receive the platform name as a platform_data parameter. This is used e.g. for HDaudio support where we have different PCI aliases used for different platforms. We can reuse the same mechanism and modify the machine drivers to override the dailinks prior to registrating the card. This will require additional work for SOF, but with this helper it'll be just two lines of additional code per machine driver which is reused, not the end of the world. This helper can be simplified when all drivers have transitioned to the "modern" representation of dailinks. While these changes are simple and largely mechanical, there is always a risk. These patches were tested with Asus T100 (rt5640), rt5651, rt5682, pcm512x, both in SST and SOF cases. Additional tests are on-going for Chromebook platforms and Broadwell. I figured it was better to share this patchset earlier to get more feedback. Note that byt-max98080, byt-rt5640 were not modified since they are deprecated. bytcht-nocodec and the Skylake/Kabylake machine drivers changes were not changed since SOF does not support them. There may be additional changes if and when Skylake/Kabylake are supported by SOF (largely a firmware authentication issue, not technical difficulty).

[alsa-devel] [PATCH v6 0/8] ASoC: Add support to WCD9335 Audio Codec
by Srinivas Kandagatla 28 Jan '19

28 Jan '19

Thankyou for reviewing v5 patchset, here is v6 addressing comments from v5. Qualcomm WCD9335 Codec is a standalone Hi-Fi audio codec IC. It is integrated in multiple Qualcomm SoCs like: MSM8996, MSM8976, and MSM8956 chipsets. WCD9335 had multiple functional blocks, like: Soundwire controller, interrupt mux, pin controller, Audio codec, MBHC, MAD(Mic activity Detection), Ultrasonic proximity and pen detection, Battery-voltage monitoring and Codec processing engine. Currently this patchset has been only tested with SLIMbus interface due to hardware avaiablity, but it can be easily made to work with both SLIMbus and I2C/I2S. This patchset adds very basic playback and capture support without much fancy features. New features will be added once the basic support is in. This patchset is tested on top of linux-next on DB820c for both playback , capture paths and MBHC. Some parts of the code has been inherited from Qualcomm andriod kernel, so credits to various authors. WCD9335 can be interfaced via I2S/I2C or SLIMbus. Here is our integration branch incase someone want to try this out: https://git.linaro.org/landing-teams/working/qualcomm/kernel.git/log/?h=int… Thanks, Srini Changes since v5 (https://patchwork.kernel.org/cover/10756015/) - Added codec to SND_SOC_ALL_CODECS, also fixed irq return as suggested by Mark. - converted ear_pa gain to proper tlv as suggested by Mark. - converted rx_hph_mode_mux_text to more human readable strings as suggested by Mark.

The patch ASoC: wcd9335: add capture dapm widgets 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: wcd9335: add audio routings 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] [RFC PATCH] ALSA: core: Add DMA share buffer support
by Baolin Wang 28 Jan '19

28 Jan '19

This patch adds dma share buffer support, which allows a dma-buf to be shared between processes by passing file descriptors between them, allowing multiple processes to cooperate in filling the DMA buffer used by the audio hardware without the need to copy data around. This reduces both latency and CPU load, especially in configurations where only one application is playing audio and so context switches can be avoided. In userspace, we can use ioctl:SNDRV_PCM_IOCTL_DMABUF_EXPORT to export one dma buffer to a PCM, and use ioctl:SNDRV_PCM_IOCTL_DMABUF_ATTACH and ioctl:SNDRV_PCM_IOCTL_DMABUF_DETACH to attach or detach one device to the dma buffer. Morevoer we can use dma buffer ioctl:DMA_BUF_IOCTL_SYNC to guarantee the cache coherency of the DMA buffer. You can refer to below patches [1] created by Leo Yan to use the dma buffer in userspace. [1] https://github.com/tinyalsa/tinyalsa/pull/126 Welcome any comments. Thanks. Signed-off-by: Baolin Wang <baolin.wang(a)linaro.org> --- Hi, Before sending to ALSA mailing list, we had some internal discussion off line, so I posted them to follow up. 1. One issue proposed by Srinivas Kandagatla, he proposed one use case example: DSP1 pre-process(compress-to-pcm) the buffers, pass the fd to DSP2/audio-ip to play pcm data. The dmabuf exporter (DSP1) is a different device than audio device in this instance, so the DSP1 device cannot call snd_pcm_dmabuf_export() to export one dma buffer and pass to the DSP2/audio-ip. Our original design is, the dma buffer should be associated with one PCM device, since different PCM devices may need different buffer types (see SNDRV_DMA_TYPE_XXX) to play PCM data, and need consider the PCM device's coherent capability for DMA memory. My concern is, if we let other non-audio device to allocate one buffer and export it, how to guarantee the dma buffer can be used by PCM device and have the same coherent capability with the PCM device. So I am not sure for this issue and need more suggestion to get a consensus. 2. Second question raised by Srinivas Kandagatla, he wondered: "Am still unclear on the whole idea making a audio device dmabuf exporter in Linux systems, unless you are sharing the dmabuf fd with other devices. If you are working with just one device we could just live with mmap, isn't it?" Mark Brown gave the answer: "The issue is permissions management. We've got a sound server that owns all the sound hardware and needs to be able to retain administrative control over it which means that permissions for the sound devices are locked down to it. For performance reasons on systems where it's practical (eg, where there's multiple audio streams the system can use to play data to the hardware) we want to be able to have that server allow other applications with lower permissions to stream data to/from the hardware without going through it. The applications can't mmap() the device directly as that's too painful to do that securely from a permission management point of view so we want to be able to have the sound server do the mmap() then hand the mapped buffer off to the application for it to use via a FD over a pipe. That way the only thing with direct access to the devices is the sound server but the clients have a data path that doesn't need to bounce through another process. Practically speaking the only use case I can think of in an audio context is for one reader and one writer (AIUI Android is envisioning this as one hardware and one software), it's difficult to see how you could usefully chain multiple in place transformations together in the way that you can with video applications but I'm possibly not thinking of something here." --- include/sound/pcm.h | 2 + include/sound/pcm_dmabuf.h | 29 +++ include/uapi/sound/asound.h | 3 + sound/core/Kconfig | 4 + sound/core/Makefile | 1 + sound/core/pcm.c | 2 + sound/core/pcm_compat.c | 3 + sound/core/pcm_dmabuf.c | 531 +++++++++++++++++++++++++++++++++++++++++++ sound/core/pcm_native.c | 38 ++++ 9 files changed, 613 insertions(+) create mode 100644 include/sound/pcm_dmabuf.h create mode 100644 sound/core/pcm_dmabuf.c diff --git a/include/sound/pcm.h b/include/sound/pcm.h index c47d9b4..d353e55 100644 --- a/include/sound/pcm.h +++ b/include/sound/pcm.h @@ -30,6 +30,7 @@ #include <linux/mm.h> #include <linux/bitops.h> #include <linux/pm_qos.h> +#include <linux/dma-buf.h> #define snd_pcm_substream_chip(substream) ((substream)->private_data) #define snd_pcm_chip(pcm) ((pcm)->private_data) @@ -455,6 +456,7 @@ struct snd_pcm_substream { size_t buffer_bytes_max; /* limit ring buffer size */ struct snd_dma_buffer dma_buffer; size_t dma_max; + struct dma_buf_attachment *attachment; /* -- hardware operations -- */ const struct snd_pcm_ops *ops; /* -- runtime information -- */ diff --git a/include/sound/pcm_dmabuf.h b/include/sound/pcm_dmabuf.h new file mode 100644 index 0000000..4e88c5f6 --- /dev/null +++ b/include/sound/pcm_dmabuf.h @@ -0,0 +1,29 @@ +#ifndef __SOUND_PCM_DMABUF_H +#define __SOUND_PCM_DMABUF_H + +#include <sound/pcm.h> + +#ifdef CONFIG_SND_PCM_DMABUF +int snd_pcm_dmabuf_export(struct snd_pcm_substream *substream); +int snd_pcm_dmabuf_attach(struct snd_pcm_substream *substream, int fd); +void snd_pcm_dmabuf_detach(struct snd_pcm_substream *substream); +#else +static inline int snd_pcm_dmabuf_export(struct snd_pcm_substream *substream) +{ + return -EBADF; +} + +static inline int snd_pcm_dmabuf_attach(struct snd_pcm_substream *substream, + int fd) +{ + return -ENXIO; +} + +static inline void snd_pcm_dmabuf_detach(struct snd_pcm_substream *substream) +{ + +} + +#endif + +#endif /* __SOUND_PCM_DMABUF_H */ diff --git a/include/uapi/sound/asound.h b/include/uapi/sound/asound.h index 404d4b9..4770b41 100644 --- a/include/uapi/sound/asound.h +++ b/include/uapi/sound/asound.h @@ -602,6 +602,9 @@ enum { #define SNDRV_PCM_IOCTL_READN_FRAMES _IOR('A', 0x53, struct snd_xfern) #define SNDRV_PCM_IOCTL_LINK _IOW('A', 0x60, int) #define SNDRV_PCM_IOCTL_UNLINK _IO('A', 0x61) +#define SNDRV_PCM_IOCTL_DMABUF_EXPORT _IOR('A', 0x70, int) +#define SNDRV_PCM_IOCTL_DMABUF_ATTACH _IOW('A', 0x71, int) +#define SNDRV_PCM_IOCTL_DMABUF_DETACH _IO('A', 0x72) /***************************************************************************** * * diff --git a/sound/core/Kconfig b/sound/core/Kconfig index 63b3ef9..5ee02f2 100644 --- a/sound/core/Kconfig +++ b/sound/core/Kconfig @@ -184,4 +184,8 @@ config SND_DMA_SGBUF def_bool y depends on X86 +config SND_PCM_DMABUF + def_bool y + select DMA_SHARED_BUFFER + source "sound/core/seq/Kconfig" diff --git a/sound/core/Makefile b/sound/core/Makefile index ee4a4a6..beea463 100644 --- a/sound/core/Makefile +++ b/sound/core/Makefile @@ -49,3 +49,4 @@ obj-$(CONFIG_SND_OSSEMUL) += oss/ obj-$(CONFIG_SND_SEQUENCER) += seq/ obj-$(CONFIG_SND_COMPRESS_OFFLOAD) += snd-compress.o +obj-$(CONFIG_SND_PCM_DMABUF) += pcm_dmabuf.o diff --git a/sound/core/pcm.c b/sound/core/pcm.c index 01b9d62..7781db2 100644 --- a/sound/core/pcm.c +++ b/sound/core/pcm.c @@ -32,6 +32,7 @@ #include <sound/timer.h> #include <sound/control.h> #include <sound/info.h> +#include <sound/pcm_dmabuf.h> #include "pcm_local.h" @@ -890,6 +891,7 @@ static void snd_pcm_free_stream(struct snd_pcm_str * pstr) substream_next = substream->next; snd_pcm_timer_done(substream); snd_pcm_substream_proc_done(substream); + snd_pcm_dmabuf_detach(substream); kfree(substream); substream = substream_next; } diff --git a/sound/core/pcm_compat.c b/sound/core/pcm_compat.c index 946ab08..af24489 100644 --- a/sound/core/pcm_compat.c +++ b/sound/core/pcm_compat.c @@ -687,6 +687,9 @@ static long snd_pcm_ioctl_compat(struct file *file, unsigned int cmd, unsigned l case SNDRV_PCM_IOCTL_XRUN: case SNDRV_PCM_IOCTL_LINK: case SNDRV_PCM_IOCTL_UNLINK: + case SNDRV_PCM_IOCTL_DMABUF_EXPORT: + case SNDRV_PCM_IOCTL_DMABUF_ATTACH: + case SNDRV_PCM_IOCTL_DMABUF_DETACH: return snd_pcm_common_ioctl(file, substream, cmd, argp); case SNDRV_PCM_IOCTL_HW_REFINE32: return snd_pcm_ioctl_hw_params_compat(substream, 1, argp); diff --git a/sound/core/pcm_dmabuf.c b/sound/core/pcm_dmabuf.c new file mode 100644 index 0000000..76211ea --- /dev/null +++ b/sound/core/pcm_dmabuf.c @@ -0,0 +1,531 @@ +// SPDX-License-Identifier: GPL-2.0+ +// +// Copyright(C) 2018 Linaro Limited.

[alsa-devel] [PATCH] ALSA: dice: add support for Solid State Logic Duende Classic/Mini
by Takashi Sakamoto 28 Jan '19

28 Jan '19

Duende Classic was produced by Solid State Logic in 2006, as a first model of Duende DSP series. The following model, Duende Mini was produced in 2008. They are designed to receive isochronous packets for PCM frames via IEEE 1394 bus, perform signal processing by downloaded program, then transfer isochronous packets for converted PCM frames. These two models includes the same embedded board, consists of several ICs below: - Texus Instruments Inc, TSB41AB3 for physical layer of IEEE 1394 bus - WaveFront semiconductor, DICE II STD ASIC for link/protocol layer - Altera MAX 3000A CPLD for programs - Analog devices, SHARC ADSP-21363 for signal processing (4 chips) This commit adds support for the two models to ALSA dice driver. Like support for the other devices, packet streaming is just available. Userspace applications should be developed if full features became available; e.g. program uploader and parameter controller. $ ./hinawa-config-rom-printer /dev/fw1 { 'bus-info': { 'adj': False, 'bmc': False, 'chip_ID': 349771402425, 'cmc': True, 'cyc_clk_acc': 255, 'generation': 1, 'imc': True, 'isc': True, 'link_spd': 2, 'max_ROM': 1, 'max_rec': 512, 'name': '1394', 'node_vendor_ID': 20674, 'pmc': False}, 'root-directory': [ ['VENDOR', 20674], ['DESCRIPTOR', 'Solid State Logic'], ['MODEL', 112], ['DESCRIPTOR', 'Duende board'], [ 'NODE_CAPABILITIES', { 'addressing': {'64': True, 'fix': True, 'prv': True}, 'misc': {'int': False, 'ms': False, 'spt': True}, 'state': { 'atn': False, 'ded': False, 'drq': True, 'elo': False, 'init': False, 'lst': True, 'off': False}, 'testing': {'bas': False, 'ext': False}}], [ 'UNIT', [ ['SPECIFIER_ID', 20674], ['VERSION', 1], ['MODEL', 112], ['DESCRIPTOR', 'Duende board']]]]} Signed-off-by: Takashi Sakamoto <o-takashi(a)sakamocchi.jp> --- sound/firewire/dice/dice.c | 12 +++++++++++- 1 file changed, 11 insertions(+), 1 deletion(-) diff --git a/sound/firewire/dice/dice.c b/sound/firewire/dice/dice.c index ed50b222d36e..eee184b05d93 100644 --- a/sound/firewire/dice/dice.c +++ b/sound/firewire/dice/dice.c @@ -18,6 +18,7 @@ MODULE_LICENSE("GPL v2"); #define OUI_ALESIS 0x000595 #define OUI_MAUDIO 0x000d6c #define OUI_MYTEK 0x001ee8 +#define OUI_SSL 0x0050c2 // Actually ID reserved by IEEE. #define DICE_CATEGORY_ID 0x04 #define WEISS_CATEGORY_ID 0x00 @@ -196,7 +197,7 @@ static int dice_probe(struct fw_unit *unit, struct snd_dice *dice; int err; - if (!entry->driver_data) { + if (!entry->driver_data && entry->vendor_id != OUI_SSL) { err = check_dice_category(unit); if (err < 0) return -ENODEV; @@ -361,6 +362,15 @@ static const struct ieee1394_device_id dice_id_table[] = { .model_id = 0x000002, .driver_data = (kernel_ulong_t)snd_dice_detect_mytek_formats, }, + // Solid State Logic, Duende Classic and Mini. + // NOTE: each field of GUID in config ROM is not compliant to standard + // DICE scheme. + { + .match_flags = IEEE1394_MATCH_VENDOR_ID | + IEEE1394_MATCH_MODEL_ID, + .vendor_id = OUI_SSL, + .model_id = 0x000070, + }, { .match_flags = IEEE1394_MATCH_VERSION, .version = DICE_INTERFACE, -- 2.19.1

[alsa-devel] [PATCH 2/2] ASoC: pcm512x: Fix clocking calculations when not using the PLL
by Dimitris Papavasiliou 28 Jan '19

28 Jan '19

The rationale behind the current calculation is somewhat obscure [1] and can yield slightly wrong dividers in certain cases, which the machine drivers for some boards (like the HiFiBerry DAC+ Pro) seemingly try to circumvent, by updating the rate fraction so as to suit this calculation. The updated calculation should correctly yield the smallest bit clock rate that would fit the frame.

[alsa-devel] Record stereo from one input on the soundcard
by Tomas Nordin 28 Jan '19

28 Jan '19

Hello List I sent this question first to the alsa-user list but somebody recommended somebody to send to this list instead when the user-list don't get much attention. I have an external USB soundcard called Audiobox from Presonus, https://www.presonus.com/products/AudioBox-USB. Somewhere I read that this is a class compliant USB sound card. I use this card to record audio from a drum module (e-drums). I take the audio signal from the head phones out socket on the module, and plug it into input 1 on the card. The card has 2 inputs, for the moment I don't use the second input but I consider it busy. For a minimum of hassle I want to make my recording using arecord (want to use a command line program). So the card is a kind of bedroom musician type of card that might have 2 inputs, 4 inputs or 12 or whatever, to record a number of instruments at the same time. But as I said, this card has two inputs. The audio signal from the headphones out socket (on the drum module) is stereo. The card support routing that stereo sound from one input, in so far that it can be heard in stereo from the cards head phones out. The following command lets me record audio from the card, $ arecord -c 2 -d 60 -f S24_3LE -r 48000 -D hw:1,0 s3.wav The resulting wav file has all hearable audio in the left speaker when listening. Do you think it is possible to get that stereo signal from one input on the card into a stereo sound file. Or somehow else get left and right audio separately from that input 1 on the card. My guess on what's happening now is that the stereo signal gets merged as mono into one channel. Here are some listings: $ uname -a Linux raspberrypi 4.14.79+ #1159 Sun Nov 4 17:28:08 GMT 2018 armv6l GNU/Linux $ arecord -l **** List of CAPTURE Hardware Devices **** card 1: USB [AudioBox USB], device 0: USB Audio [USB Audio] Subdevices: 1/1 Subdevice #0: subdevice #0 $ arecord --dump-hw-params -D hw:1,0 Recording WAVE 'stdin' : Unsigned 8 bit, Rate 8000 Hz, Mono HW Params of device "hw:1,0": -------------------- ACCESS: MMAP_INTERLEAVED RW_INTERLEAVED FORMAT: S24_3LE SUBFORMAT: STD SAMPLE_BITS: 24 FRAME_BITS: 48 CHANNELS: 2 RATE: [44100 48000] PERIOD_TIME: [1000 1981429) PERIOD_SIZE: [45 87381] PERIOD_BYTES: [270 524286] PERIODS: [2 1024] BUFFER_TIME: [1875 3962858) BUFFER_SIZE: [90 174762] BUFFER_BYTES: [540 1048572] TICK_TIME: ALL -------------------- arecord: set_params:1299: Sample format non available Available formats: - S24_3LE Any ideas anyone?

This userspace is mostly compliant to POSIX:2008 and some additional macros for poll event are officially available. The glibc supports them as a default since its v2.12 release. It will be failed to be compiled with old glibc or the other libraries for C standard APIs. One of the purpose of axfer is an better alternative of aplay. In a point of the purpose, it's preferable to be compiled with the old libraries. This commit adds conditional macros to be compiled with libraries for old compliance level of POSIX. This fixes #9 .

26 Jan '19

The patchset adds NXP Audio Mixer (AUDMIX) device and machine drivers and related DT bindings documentation. Changes since V2: 1. Moved "dais" node from machine driver DTS node to device driver DTS node as suggested by Rob. Changes since V1: 1. Original patch split into distinct patches for the device driver and DT binding documentation. 2. Replaced AMIX with AUDMIX in both code and file names as it looks more RM-compliant. 3. Removed polarity control from CPU DAI driver as suggested by Nicolin. 4. Added machine driver and related DT binding documentation.

[alsa-devel] [PATCH] ASoC: core: Allow soc_find_component lookups to match parent of_node
by Charles Keepax 25 Jan '19

25 Jan '19

For devices implemented as a MFD it is common to only have a single node in devicetree representing the whole device. As such when looking up components in soc_find_components we should match against both the devices of_node and the devices parent's of_node, as is already done in the rest of the ASoC core. This causes regressions for some DAI links at the moment as soc_find_component was recently added as a check in soc_init_dai_link.

This can be problematic for a capture stream, unfortunately, like the following, as detected by syzkaller: - In __snd_pcm_lib_xfer() that is invoked from snd_pcm_oss_read() loop, we have a check whether the stream was already started or the stream can be auto-started. - With trigger=0, we explicitly disable the auto-start, and the function returns 0 at this check. - The loop continues tightly, which may lead to an RCU stall. This patch fixes the bug by simply allowing the wait for non-started stream in the case of OSS capture. For native usages, it's supposed to be done by the caller side (which is user-space), hence it returns zero like before. (In theory, this could wait there, but I'd like to stay in a safer side for not breaking the existing stuff.)
