[alsa-devel] Softvol only after device has opened
by Ricard Wanderlof 09 Jun '15

09 Jun '15

I'm working on implementing support for a MEMS microphone with an I2S connection. Since the microphone has no controls but simply outputs I2S data from the word go, this means that any gain must be applied later. (Microphones of this type are generally specified at outputting 0 dB FS at some rediculously high SPL, 120 dB SPL being typical). Since we use 16 bit audio in our (SOC) system, I'm trying to apply gain using the softvol ALSA plugin, before converting to 16 bit audio (the microphone outputs 24 bit audio). One thing though, the 'softvol' plugin very correctly creates a mixer control and it all works fine, but only after the device has been opened. Before that the mixer control doesn't seem to exist, which means that we cannot adjust the gain until the device is opened by some application. Is this intentional, a bug, or something that is misconfigured on my part? /Ricard -- Ricard Wolf Wanderlöf ricardw(at)axis.com Axis Communications AB, Lund, Sweden www.axis.com Phone +46 46 272 2016 Fax +46 46 13 61 30

[alsa-devel] [PATCH] PCM: snd_pcm_dmix_drain() maybe blocked after suspend and resume
by Shengjiu Wang 09 Jun '15

09 Jun '15

After suspend and resume, the alsa driver is stopped. But if alsa-lib run into snd_pcm_dmix_drain(), it need to wait avail >= pcm->stop_threshold, otherwise, it will not exit the loop, so finally it is blocked at poll() of snd_pcm_wait_nocheck(pcm, -1). This patch is to add state check after snd_pcm_wait_nocheck(pcm, -1), if the state is SND_PCM_STATE_SUSPENDED, then return error.

[alsa-devel] regression in device count on hotplug
by Dave Airlie 09 Jun '15

09 Jun '15

Hi, I've been looking at mst support a bit more, and noticed a regression in the number of devices probing between 4.0 and 4.1 On 4.0 if I boot with no dock, and cat /proc/asound/HDMI/codec#0 Node 0x06 has Devices: 0 if I dock I get Devices: 3, and the info about the 3 devices. On 4.1-rc6 if I boot with no dock, and cat I get Devices:0, however when I dock, I still get Devices: 0 I haven't had time to bisect yet, but was hoping someone might be able to spot it from the symptoms. Dave.

After remove the redundant internal speaker, 5.1 is only available after you change the channel mode Can alsactl restore the channel mode before pulseaudio probe the sound cards ? Auto mic select is not enabled when the notebook has mic jack and line in jack , internl mic As jack retasking is specific to snd-hda-intel and some multi cjannel ac97 codecs It is not easy to force pulseaudio to stop all client connection, reprobe the profiles on board audio after jack retasking hdajackretask also perform the same function stop pulseaudio and using dynamic reconfiguration/early patching For those notebook with headphone spdif combo jack, it need a customised iec958.conf and you can use headphone jack to make iec958 unavailable http://cgit.freedesktop.org/pulseaudio/pulseaudio/tree/src/modules/alsa/mix… [Jack Headphone] state.plugged = no state.unplugged = unknown

[alsa-devel] [GIT PULL] ASoC updates for v4.2
by Mark Brown 08 Jun '15

08 Jun '15

The following changes since commit c65b99f046843d2455aa231747b5a07a999a9f3d: Linux 4.1-rc6 (2015-05-31 19:01:07 -0700) are available in the git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git tags/asoc-v4.2 for you to fetch changes up to 11e688862c4c8162119a4ca51c3326555966c8bb: Merge remote-tracking branches 'asoc/topic/wm8994', 'asoc/topic/wm8996' and 'asoc/topic/zx' into asoc-next (2015-06-05 18:55:07 +0100) ---------------------------------------------------------------- ASoC: Updates for v4.2 The big thing this release has been Liam's addition of topology support to the core. We've also seen quite a bit of driver work and the continuation of Lars' refactoring for component support. - Support for loading ASoC topology maps from firmware, intended to be used to allow self-describing DSP firmware images to be built which can map controls added by the DSP to userspace without the kernel needing to know about individual DSP firmwares. - Lots of refactoring to avoid direct access to snd_soc_codec where it's not needed supporting future refactoring. - Big refactoring and cleanup serieses for the Wolfson ADSP and TI TAS2552 drivers. - Support for TI TAS571x power amplifiers. - Support for Qualcomm APQ8016 and ZTE ZX296702 SoCs. - Support for x86 systems with RT5650 and Qualcomm Storm. ---------------------------------------------------------------- Alexander Stein (2): ASoC: sgtl5000: Use specific variable for lo_vag ASoC: sgtl5000: Calculate Lineout Channel Output Level Alexandre Belloni (2): ASoC: atmel: simplify Kconfig ASoC: atmel: compile pcm driver in snd-soc-atmel_ssc_dai Anatol Pomozov (1): ASoC: rt5677: Add reset-gpio dts option Antonio Ospite (1): ASoC: adau1977: fix typo s/Substraction/Subtraction/ Arnd Bergmann (3): ASoC: omap: fix up SND_OMAP_SOC_OMAP_ABE_TWL6040 dependency, again ASoC: qcom: remove incorrect dependencies ASoC: qcom: fix STORM board Kconfig Axel Lin (7): ASoC: da7210: Fix dependency to allow build with SND_SOC_I2C_AND_SPI ASoC: sta32x: Use devm_gpiod_get_optional at appropriate place ASoC: sta350: Use devm_gpiod_get_optional at appropriate place ASoC: wm8737: Fixup setting VMID Impedance control register ASoC: wm8903: Fix define for WM8903_VMID_RES_250K ASoC: wm8955: Fix setting wrong register for WM8955_K_8_0_MASK bits ASoC: max98925: Fix mask for setting DAI invert mode Bard Liao (10): ASoC: rt5645: Adds push button support for rt5650 ASoC: rt5677: add i2s asrc clk src selection ASoC: rt5645: fix implicit declaration error ASoC: rt5645: fix wrong mask for button report ASoC: rt5645: remove RT5645_I2S_BCLK_MS1 control ASoC: rt5645: fix PLL source register definitions ASoC: rt5645: add TDM slot control into dapm route ASoC: rt5645: make volume TLV closer to reality ASoC: rt5645: fix add missing widget ASoC: rt5645: remove unused field in pdata Charles Keepax (22): ASoC: wm_adsp: Split out adsp1 & 2 setup algorithms ASoC: wm_adsp: Improve variable naming ASoC: wm_adsp: Remove len field from wm_adsp_alg_region ASoC: wm_adsp: Limit firmware control name to ALSA control name size ASoC: wm_adsp: Move temporary control name to the stack ASoC: wm_adsp: Clean up low level control read/write functions ASoC: wm_adsp: Factor out creation of alg_regions ASoC: wm_adsp: Remove private field from wm_coeff_ctl ASoC: wm_adsp: Group all the ALSA control functions together ASoC: wm_adsp: Add basic support for rev 1 firmware file format ASoC: wm_adsp: Add support for rev 2 firmware file format ASoC: wm_adsp: Warn that firmware file format 0 is depreciated ASoC: wm_adsp: Use __leXX for little endian data ASoC: wm_adsp: Add support for DSP control flags ASoC: dapm: Remove local OOM error message ASoC: Correct typo in SOC_VALUE_ENUM_SINGLE macro ASoC: dapm: Append "Autodisable" to autodisable widget names ASoC: dapm: Add support for autodisable mux controls ASoC: arizona: Use auto disable muxes for routing ASoC: dapm: Add missing mutex unlock ASoC: dapm: Break out of widget search when source and sink are located ASoC: dapm: Add cache to speed up adding of routes Dan Carpenter (1): ASoC: wm8741: check for error returns from wm8741_set_pdata() Dylan Reid (2): ASoC: Add jack types to dt-bindings ASoC: jack -

[alsa-devel] [PATCH] alsactl: Try to create state file directory
by Dan Nicholson 08 Jun '15

08 Jun '15

Try to create the directory for the state file when saving so we don't depend on it being created ahead of time. This only checks for failures on existing directories and doesn't try to create the leading directories or workaround any other errors. This should catch the common case where /var/lib exists, but /var/lib/alsa doesn't.

[alsa-devel] [PATCH v2] ASoC: wm8741: Allow master clock switching
by Sergej Sawazki 08 Jun '15

08 Jun '15

The set of supported sample rates depends on the master clock supplied to the codec. Allow the machine driver to set the required master clock in hw_params(). Signed-off-by: Sergej Sawazki <ce3a(a)gmx.de> --- Charles, Mark, thanks for your comments. This patch has been tested on a board with two master clocks, 22.5792MHz (for 44.1kHz, 88.2kHz, ...) and 24.576MHz (for 48kHz, 96kHz, ...). Changes since v1 (Suggested by Charles Keepax): - Do not entirely delete the startup() method, just don't set any constraints if there is no SYSCLK configured. - Clear the SYSCLK in set_dai_sysclk() if freq is 0.

[alsa-devel] [PATCH v3 0/9] ASoC: tas2552: Fixes, cleanups and improvements
by Peter Ujfalusi 08 Jun '15

08 Jun '15

Hi, Changes since v02: - Dropped already applied patches from v02 - Fix bit shift in the PLL configuration patch (1/9) and add macro for it for readability - New patches since v02: - fix module removing and loading issue by calling pm_runtime_disable when the module is removed - Remove extra semicolon - Consitent naming for 'struct tas2552_data': tas_data -> tas2552 - Binding document update regarding to the added header file for clock selection Changes since v01: - missing patch found. It was merged with the previous patch while fixing checkpatch errors (patch 19 got squashed to patch 18) - Sorry for this. I have used the TAS2552-EVM to verify that my setup is in working condition for a work on other audio product. During the bringup of the EVM I have faced some issues and limitation with the driver. The result is this series against the tas2552 driver. Notable changes: - Fixes for kernel crashes - The enable-gpio was not optional as it was documented in the DTS - Register bit definitions were not correct in several places - Adding recommended startup/stop sequence - Handling of sample formats the driver claims to support - PLL configuration fixes and reference clock selection - TDM support - Gain control fix and control to select DIN source Regards, Peter --- Peter Ujfalusi (9): ASoC: tas2552: Correct the PLL configuration ASoC: tas2552: Add control for selecting DIN source ASoC: tas2552: Correct Output Data register usage ASoC: tas2552: Correct Boost Auto-Pass Through Control register usage ASoC: tas2552: Code, define alignment changes for uniformity ASoC: tas2552: Call pm_runtime_disable when the module is removed ASoC: tas2552: Remove unneeded semicolon ASoC: tas2552: Use consistent name for 'struct tas2552_data' ASoC: tas2552: Update DT binding document regarding clkock configuration .../devicetree/bindings/sound/tas2552.txt | 6 + sound/soc/codecs/tas2552.c | 173 ++++++++++++++------- sound/soc/codecs/tas2552.h | 61 ++++---- 3 files changed, 155 insertions(+), 85 deletions(-) -- 2.4.2

[alsa-devel] [PATCH] ASoC: davinci-mcasp: Logic low for inactive output slots
by Peter Ujfalusi 08 Jun '15

08 Jun '15

From: Misael Lopez Cruz <misael.lopez(a)ti.com> The default state when serializers are in inactive slots is Hi-Z. In some cases, there are no additional components driving the data lines to a safe state so they might have noise. While in inactive slots, the McASP AXR pins configured as outputs can be driven low through the serializer pin drive mode setting (DISMOD) to prevent such noise.

[alsa-devel] [RFC][PATCH 00/11] improve support for DM1500/BeBoBv3
by Takashi Sakamoto 08 Jun '15

08 Jun '15

Hi, This patchset is to improve support for DM1500 and BeBoBv3; DM1500 is an ASIC which ArchWave produced. BeBoB is an interface protocol for DM series firmware. Currently, Some devices are reported not to work with current ALSA BeBoB driver. [FFADO-user] Support Behringer UFX1604 http://sourceforge.net/p/ffado/mailman/message/32846563/ [alsa-devel] snd-bebob and PrismSound Orpheus fails with snd_pcm_hw_params_set_channels http://mailman.alsa-project.org/pipermail/alsa-devel/2015-April/090967.html They commonly install BeBoB version 3 firmware. As long as seeing these devices, they may have below quirks comparing to version 1 and 2. Furthermore, DM1500 seems to have its own quirks. The first half of this patchset is for improvement of clock detection, the rest is for quirks. The latter is tested by Kim Tore Jensen (Thanks!), while the first half is not widely tested. I hope someone to test it till opening next merge window (but just one week rest!). I push these patches into my own repository. It's DKMS available. https://github.com/takaswie/snd-firewire-improve/tree/bebob3 Regards Takashi Sakamoto (11): ALSA: bebob: improve signal mode detection for clock source ALSA: bebob: apply new enumerator to normalize the type of clock source ALSA: bebob: preparation for replacing string literals by normalized representation for model-dependent structures ALSA: bebob: use normalized representation for the type of clock source ALSA: bebob: obsolete string literal expression for clock source ALSA: bebob: add SYT-Match support ALSA: bebob: add 'version' member for BeBoB protocol version ALSA: bebob: expand timeout for DM1500 quirk ALSA: bebob: loosen up severity of checking continuity for BeBoB v3 quirk ALSA: bebob: keep duplex streams always to keep internal multiplexer properly ALSA: bebob: add support for Behringer FCA 610/1616 sound/firewire/Kconfig | 1 + sound/firewire/bebob/bebob.c | 14 ++- sound/firewire/bebob/bebob.h | 17 ++-- sound/firewire/bebob/bebob_focusrite.c | 33 +++++--- sound/firewire/bebob/bebob_maudio.c | 23 +++-- sound/firewire/bebob/bebob_midi.c | 8 +- sound/firewire/bebob/bebob_pcm.c | 14 +-- sound/firewire/bebob/bebob_proc.c | 22 ++--- sound/firewire/bebob/bebob_stream.c | 150 ++++++++++++++++++++++++--------- sound/firewire/bebob/bebob_terratec.c | 30 +++++-- sound/firewire/bebob/bebob_yamaha.c | 20 ++++- 11 files changed, 233 insertions(+), 99 deletions(-) -- 2.1.4

Hello, I can't get 4.0/5.1 sound working on my laptop [0] [1] with Fedora 22. With Linux 4.0 there is no output on jacks but with 4.1-rc6 I'm getting sound only on one output. Switching between pacmd set-card-profile alsa_card.pci-0000_00_1b.0 output:analog-stereo and pacmd set-card-profile alsa_card.pci-0000_00_1b.0 output:analog-surround-40 only boosts the volume on the first output.

[alsa-devel] [PATCH v2 00/23] ASoC: tas2552: Fixes, cleanups and improvements
by Peter Ujfalusi 08 Jun '15

08 Jun '15

Hi, Changes since v01: - missing patch found. It was merged with the previous patch while fixing checkpatch errors (patch 19 got squashed to patch 18) - Sorry for this. I have used the TAS2552-EVM to verify that my setup is in working condition for a work on other audio product. During the bringup of the EVM I have faced some issues and limitation with the driver. The result is this series against the tas2552 driver. Notable changes: - Fixes for kernel crashes - The enable-gpio was not optional as it was documented in the DTS - Register bit definitions were not correct in several places - Adding recommended startup/stop sequence - Handling of sample formats the driver claims to support - PLL configuration fixes and reference clock selection - TDM support - Gain control fix and control to select DIN source Regards, Peter --- Peter Ujfalusi (23): ASoC: tas2552: Make the enable-gpio really optional ASoC: tas2552: Fix kernel crash when the codec is loaded but not part of a card ASoC: tas2552: Fix kernel crash caused by wrong kcontrol entry ASoC: tas2552: Correct PDM configuration register bit definitions ASoC: tas2552: Correct CFG1 register bit definitions ASoC: tas2552: Simplify the tas2552_mute function ASoC: tas2552: Simplify and reverse the functionality of tas2552_sw_shutdown ASoC: tas2552: Rename mclk parameter to pll_clkin to match with the datasheet DT/sound: bindings header file for tas2552 codec ASoC: tas2552: Add support for pll and pdm source clock selection ASoC: tas2552: Correct dai format support ASoC: tas2552: Correct and clean up data format and BCLK/WCLK direction ASoC: tas2552: Add TDM support ASoC: tas2552: Clean up the Digital - Analog DAPM route definition ASoC: tas2552: Correct the Speaker Driver Playback Volume (PGA_GAIN) ASoC: tas2552: Implement startup/stop sequence as per TRM ASoC: tas2552: Add support for word length configuration ASoC: tas2552: Configure the WCLK frequency based on the stream ASoC: tas2552: Correct the PLL configuration ASoC: tas2552: Add control for selecting DIN source ASoC: tas2552: Correct Output Data register usage ASoC: tas2552: Correct Boost Auto-Pass Through Control register usage ASoC: tas2552: Code, define alignment changes for uniformity include/dt-bindings/sound/tas2552.h | 18 ++ sound/soc/codecs/tas2552.c | 435 +++++++++++++++++++++++++++--------- sound/soc/codecs/tas2552.h | 149 ++++++------ 3 files changed, 431 insertions(+), 171 deletions(-) create mode 100644 include/dt-bindings/sound/tas2552.h -- 2.4.2

[alsa-devel] Front speakers doesn't work in multichannel output, regression in ALC888
by Łukasz Wojniłowicz 07 Jun '15

07 Jun '15

Hi all, My problem is that when I set channel output to "Analog output surround 5.1" (or 2.1 or 4.1), I hear no sound in front speakers, but in case of 5.1 or 4.1 I can hear sound in rear speakers. I use kernel 3.19.5 and it didn't happen in earlier kernels that is 3.18 and in 3.17 for sure. My configuration is: OS: Fedora 21 64 bit SoundCard: ALC888 Model name: acer-aspire-4930g Laptop: Acer Aspire 5930g Speakers: external 5.1 with 3 jacks Sound channel configuration module is standard configuration module from KDE. Additional info: 1) When channel output is 5.1 and I unplug green jack and leave two others jacks connected then I can hear sound in laptop internal speakers. 2) Earlier (kernel 3.18 and 3.17) I didn't have possibility to choose 2.1 configuration and additionally to 4.1 configuration I could also choose 4.0 configuration. Thanks for looking into problem. Cheers LW

[alsa-devel] [PATCH v2 0/2] Update ALSA driver to use media controller API
by Shuah Khan 06 Jun '15

06 Jun '15

This patch series updates ALSA driver to use media controller API to share tuner with DVB and V4L2 drivers that control AU0828 media device. Two new interfaces are added to media controller API to enable creating media device as a device resource. This allows creating media device as a device resource on the main struct device that is common to all drivers that control a single media hardware and share resources on it. Drivers then can find the common media device to register entities and manage links, and pipelines. Tested with and without CONFIG_MEDIA_CONTROLLER enabled. Tested tuner entity doesn't exist case as au0828 v4l2 driver is the one that will create the tuner when it gets updated to use media controller API. Please note that au0828 updates media controller are necessary before the resource sharing can work across ALSA and au0828 dvb and v4l2 drivers. This work is in progress and another developer is working on it. Changes since v1: - Moved media specific code into new header and source file - Created a new structure for media controller specific fields - Added a new define USE_MEDIA_CONTROLLER to add media specific code. This new define is defined only when Media Controller support is enabled. New media specific code is active only when this define is defined. - Moved media_deviced_delete() check under !was_shutdown block - Removed return check for media_device_init() - Changed new Media Controller interface names for clarity. Now they are named media_device_get_devres() and media_device_find_devres(). - Calling media_entity_pipeline_stop() on a pipe that isn't active appears to be safe. This needs further testing once AU0828 media controller patches are ready.

[alsa-devel] [PATCH] ASoC: wm8731: initialize the hardware when loading the codec driver
by Sergey Kiselev 05 Jun '15

05 Jun '15

From: Sergey Kiselev <sergey.kiselev(a)intel.com> This patch moves the requesting supplies, hardware reset and initialization from wm8731_probe to wm8731_i2c_probe and wm8731_spi_probe. So that the codec hardware is initialized when loading the codec driver, and not when loading the machine driver. This avoids unnecesary hardware resets and re-initializations when re-loading the machine driver.

[alsa-devel] [PATCH v2] ASoC: dapm: fix prefixed stream name matching in snd_soc_dapm_link_dai_widgets
by Arnaud Mouiche 05 Jun '15

commit "ASoC: dapm: Modify widget stream name according to prefix" fixed a part of the problem when dai_w->name and w->sname are equal before being prefixed. Remains the case where w->sname is only a sub string of dai_w->name. For example, TLV320AIC3x codec defines the widget SND_SOC_DAPM_DAC("Left DAC", "Left Playback", DAC_PWR, 7, 0) In snd_soc_dapm_link_dai_widgets, we will failed to match "[prefix] Left Playback" with "[prefix] Playback". Since dai_w and w necessarily belongs to the same dapm when strstr() is called, they necessarily have the same prefix which allow us to compare 'w->sname + prefix_len' with 'dai_w->name + prefix_len' directly without length check.

[alsa-devel] Reflections on implementing Web MIDI on top of ALSA seq
by Adam Goode 05 Jun '15

05 Jun '15

Hi, Chrome 43 is now in beta, with Web MIDI support. (http://blog.chromium.org/2015/04/chrome-43-beta-web-midi-and-upgrading.html) The Linux (and Chrome OS) version of Chrome uses ALSA seq to implement Web MIDI. I wanted to reflect a bit on some of the issues I discovered while implementing this new API on top of seq. This is a little bit long, so the tl;dr is: * ALSA seq worked pretty well for implementing Web MIDI, but I need a way to get the card number for a given client, before my assumptions about the kernel break. Here is a quick overview of Web MIDI (http://www.w3.org/TR/webmidi/): - provides hotplug events for port connect/disconnect - incoming events are timestamped - outgoing events can be timestamped for future delivery by the system - timestamps are high precision, and use a monotonic clock - the port abstraction contains "name", "manufacturer", and "version" fields - open ports auto-reconnect if the port disappears and reappears, for both send and receive - input and output ports are distinct: there are no duplex ports - uses MIDI bytestreams (not an event structure), but requires full MIDI messages to be sent The initial prototype of Chrome's Web MIDI support was built on top of rawmidi. I rewrote it to use seq instead (to get multiple client and user client access). Here are my observations: - Getting the "manufacturer" is very hard from seq. I needed to join against udev data, which relies on the current implementation of ALSA in the kernel. These udev attributes are also used to match for transparent reconnect. - I could not use the kernel seq timestamp, either for send or receive, since I could not get it to just use a CLOCK_MONOTONIC offset. Instead, timestamping is done in userspace. - Hotplug was tricky, since I needed to listen to both seq events and udev events. I would prefer just to use udev, since I have to anyway. I definitely want to fix the kernel so that I can stop relying on a few implementation details. Here are the current assumptions I am making: - Card based clients start at 16. (I need to know which clients actually have cards) - Clients are in the same order as cards. - There is a 1:1 correspondence between clients and OPL3+rawmidi devices. One way to fix these assumptions would be to fully expose all seq events through sysfs. Right now, there is a seq device in sysfs but it has no information. Here are some ways that the kernel might be extended to simplify the code and/or fix bad assumptions: 1. Expose all seq clients+ports as kobjects, with a symlink to the card if it's a hardware device 2. Expose all subscriptions through sysfs 3. Add a simplified timestamp mechanism that just uses a configurable system clock, with at least CLOCK_MONOTONIC available (something like what sound/core/timer.c does with tread?) The first change would allow me to eliminate all the hardcoded assumptions about which cards correspond to which clients. I believe it would also allow me to drive the hotplug logic directly from udev, instead of both udev and seq. The second change is not strictly necessary, but would remove more need to react to seq events for some uses. The third change would allow me to use the kernel timestamp reliably, since right now I timestamp events with CLOCK_MONOTONIC in userspace. If I had to start today and create a new MIDI kernel interface for ALSA, it would look like this: not-quite-raw-midi: - hotplug events completely driven by sysfs - ability to interoperate with existing seq clients (for kernel and user clients) - non-exclusive access - reads and writes use a simple structured format, with timestamp and a midi message as bytes - no or minimal alsa-lib needed - one device file per port (no subdevices) - some mechanism for creating userspace clients, preferably with some number of key-value attributes (so I can report "manufacturer" and other things if the user client sets it) Thanks for reading these reflections. Comments are welcome. Adam

[alsa-devel] Different codecs for playback and capture?
by Ricard Wanderlof 04 Jun '15

04 Jun '15

Hi, I'm developing a machine driver for a system where we have two different codecs for input and output, connected to the same I2S interface. Normally a machine driver specifies which codec the I2S interface is connected to, but in this case there should really be two different ones, one for record and one for playback. I'm working on how to put this together, and just thought I'd try and get some input before going too far down the wrong track. The options I see are: 1. Specify two different codecs in the machine driver. Since one can specify several dai_links this would seem to be doable, however, I'm not sure ALSA can handle two codecs sharing a single CPU DAI in this way? 2. Use two separate machine drivers, one for each codec? Again, sharing a single CPU DAI would seem to be an issue here? 3. Write a special codec driver that is a merge between the two codecs, one for input and one for output. Seems like a bit of a hack, but should be possible. Any spontaneous thoughts? /Ricard -- Ricard Wolf Wanderlöf ricardw(at)axis.com Axis Communications AB, Lund, Sweden www.axis.com Phone +46 46 272 2016 Fax +46 46 13 61 30

[alsa-devel] standalone dmic with omap-dmic
by Jack Mitchell 04 Jun '15

04 Jun '15

I have been trying to get a dmic connected directly into an omap44xx working standalone (no twl6040), so far, unsucessfully. Does anyone know if this is even possible? I have tried with a simple-audio-card setup using the dmic-codec and omap-dmic as the dai. I have also tried hacking out the twl6040 parts of the twl6040 driver to get a dmic only driver. With both of these methods I managed to get the drivers loaded but could get nothing recorded with an Input/Output error, and then on retry a kernel lockup with regards to enabling/disablig the dmic. Doe anyone have any suggestions; or maybe an idea if this is even possible without large changes? Does the dmic driver with twl6040 even work anymore; I expect it doesn't get a lot of testing... Cheers, Jack.

[alsa-devel] Still have problems/issues using SGTL5000 with i.MX28 CPU
by gianluca 04 Jun '15

Hello everybody! I put all those people on Cc: because of I think every guy can be able to handle the issue for its side easly. I started a discussion in FreeScale Community website: https://community.freescale.com/thread/356362 Basically I designed 4 boards using the IMX28EVK board as reference. Usually the audio section was a buzzer (pwm), or simply using a SGTL5000 as playback only. Now we need to record some sounds as soon as the SGTL5000 has the SAIF1 line used for caputure (line in / mic in). In alsamixer I can see all those stuff, and actually it works (for example if I bypass the ADC part to listen any MIC or LINE-IN into headphones directly) so I can safely exclude some alsa misprogramming code or whatever. I tested my bootlets, barebox bootloader, linux kernel 3.12.1 and Debian Wheezy 7.8 in both boards: * my board (namely EK340) * IMX28VK board. Both bootcodes and barebox bootloader are almost the same in both boards (some uart definitions differ). The linux kernel _IS_ the same. The device-tree blob are quite similar: Here is the IMX28EVK dts: > /* > * Copyright 2012 Freescale Semiconductor, Inc. > * > * The code contained herein is licensed under the GNU General Public > * License.

In both boards (IMX28EVK and EK340) the VDDD pin is left floating so it uses the internal ldo voltage regulator. In IMX28EVK and in EK340 the VDDIO is from the VDDIO_3V3 from the SoC pin. In IMX28EVK the VDDA in tied/coupled with a choke (L2 470Ohm) to VDDIO, but in EK340 is using an external 3V3 voltage regulator that is triggered by VDDIO_3V3 to obtain the 3V3 voltage to the VDDA, so I can assume it is _almost_ the same. The same voltage regulator is used as power supply to all i2c stuff (RTC, EEPROM, GPIO Expander,...). VDDIO_3V3 from Soc is quite limited as current output so I choose to use an external 3V3 regulator. If I run: > arecord -t wav -d 5 -d hw:0,1 -f S16_LE -c 2 /tmp/sample.wav in the IMX28EVK it works as expected (I can clearly see I2C lines moving and SAIF1 lines moving too...) in the EK340 I can see the same lines moving (I2C and SAIF1) _BUT_ it hangs for 10 seconds and fails with an error: > arecord: pcm_read:1801: read error: Input/output error and the only thing it writes it is the WAV HEADER (44 bytes). I saw all stuff regarding SGTL5000 issues on the FSL Community: > https://community.freescale.com/thread/300291 > https://community.freescale.com/message/328708#328708 > https://community.freescale.com/thread/307611#331003 and this morning I found this too: > https://community.freescale.com/message/496426#496426 Now I can check this out too, but I am very UNCONFIDENT it will NO USEFUL to me, as in the EVK everything is working, meanwhile in EK340 it does not work for record, but only for playback... :-( Last but not least the boards are different by SoC version: IMX28EVK is using i.MX287 EK340 is using i.MX286 Any help, clue or whatever I can check and try to find out this problem???

[alsa-devel] [PATCH 00/22] ASoC: tas2552: Fixes, cleanups and improvements
by Peter Ujfalusi 04 Jun '15

04 Jun '15

Hi, I have used the TAS2552-EVM to verify that my setup is in working condition for a work on other audio product. During the bringup of the EVM I have faced some issues and limitation with the driver. The result is this series against the tas2552 driver. Notable changes: - Fixes for kernel crashes - The enable-gpio was not optional as it was documented in the DTS - Register bit definitions were not correct in several places - Adding recommended startup/stop sequence - Handling of sample formats the driver claims to support - PLL configuration fixes and reference clock selection - TDM support - Gain control fix and control to select DIN source Regards, Peter --- Peter Ujfalusi (22): ASoC: tas2552: Make the enable-gpio really optional ASoC: tas2552: Fix kernel crash when the codec is loaded but not part of a card ASoC: tas2552: Fix kernel crash caused by wrong kcontrol entry ASoC: tas2552: Correct PDM configuration register bit definitions ASoC: tas2552: Correct CFG1 register bit definitions ASoC: tas2552: Simplify the tas2552_mute function ASoC: tas2552: Simplify and reverse the functionality of tas2552_sw_shutdown ASoC: tas2552: Rename mclk parameter to pll_clkin to match with the datasheet DT/sound: bindings header file for tas2552 codec ASoC: tas2552: Add support for pll and pdm source clock selection ASoC: tas2552: Correct dai format support ASoC: tas2552: Correct and clean up data format and BCLK/WCLK direction ASoC: tas2552: Add TDM support ASoC: tas2552: Clean up the Digital - Analog DAPM route definition ASoC: tas2552: Correct the Speaker Driver Playback Volume (PGA_GAIN) ASoC: tas2552: Implement startup/stop sequence as per TRM ASoC: tas2552: Add support for word length configuration ASoC: tas2552: Configure the WCLK frequency based on the stream ASoC: tas2552: Add control for selecting DIN source ASoC: tas2552: Correct Output Data register usage ASoC: tas2552: Correct Boost Auto-Pass Through Control register usage ASoC: tas2552: Code, define alignment changes for uniformity include/dt-bindings/sound/tas2552.h | 18 ++ sound/soc/codecs/tas2552.c | 435 +++++++++++++++++++++++++++--------- sound/soc/codecs/tas2552.h | 149 ++++++------ 3 files changed, 431 insertions(+), 171 deletions(-) create mode 100644 include/dt-bindings/sound/tas2552.h -- 2.4.2

[alsa-devel] [PATCH 0/7] ASoC: remove bitwise operations on GPIO level value
by Vladimir Zapolskiy 04 Jun '15

04 Jun '15

The series does not contain any functional changes, it touches only implementation of gpiolib .set and .direction_output callbacks. The main intention of the change is to remove bitwise operations on GPIO high/low level value as a preceding change before updating gpiolib callback signatures to utilize bool type as a representation of GPIO level. The change covers all input cases of GPIO level (i.e. .set and .direction_output) in sound/*, also the series contains a small clean-ups in rt5677 and wm8903 codec drivers related to gpiolib callbacks. Vladimir Zapolskiy (7): ASoC: rt5677: add GPIO helper macros ASoC: rt5677: clean up gpiolib callbacks ASoC: wm8903: generalize GPIO control register bits ASoC: wm8903: simplify gpiolib callbacks ASoC: wm5100: remove bitwise operations involving GPIO level value ASoC: wm8962: remove bitwise operations involving GPIO level value ASoC: wm8996: remove bitwise operations involving GPIO level value include/sound/wm8903.h | 222 ++++++++-------------------------------------- sound/soc/codecs/rt5677.c | 32 +++++-- sound/soc/codecs/rt5677.h | 6 ++ sound/soc/codecs/wm5100.c | 21 ++--- sound/soc/codecs/wm8903.c | 44 ++++----- sound/soc/codecs/wm8962.c | 13 ++- sound/soc/codecs/wm8996.c | 11 ++- 7 files changed, 112 insertions(+), 237 deletions(-) -- 2.1.4

[alsa-devel] [PATCH v3 1/3] ASoC: topology: Add topology UAPI header
by Liam Girdwood 03 Jun '15

03 Jun '15

The ASoC topology UAPI header defines the structures required to define any DSP firmware audio topology and control objects from userspace. The following objects are supported :- o kcontrols including TLV controls. o DAPM widgets and graph elements o Vendor bespoke objects. o Coefficient data o FE PCM capabilities and config. o BE link capabilities and config. o Codec <-> codec link capabilities and config. o Topology object manifest. The file format is simple and divided into blocks for each object type and each block has a header that defines it's size and type. Blocks can be in any order of type and can either all be in a single file or spread across more than one file. Blocks also have a group identifier ID so that they can be loaded and unloaded by ID.

[alsa-devel] [PATCH] ASoC: fsl: Correct FSL_SAI_CR2_MSEL_MASK definition
by Takashi Iwai 03 Jun '15

03 Jun '15

The bit mask FSL_SAI_CR2_MSEL_MASK is defined as (0xff << 26) and this obviously overflows the 32bit integer. Also this clears other bits than the needed ones (FSL_SAI_CR2_MSEL_XXX) wrongly. This patch fixes the definition only to mask bits 26 and 27.

[alsa-devel] simple-audio-card with omap4-dmic
by Jack Mitchell 03 Jun '15

03 Jun '15

I'm currently working with a PandaBoard clone (OMAP44xx) which doesn't have the usual twl6040 codec, however I would like to attach a digital microphone directly into the OMAP. I have added the following to my device tree: sound { compatible = "simple-audio-card"; simple-audio-card,name = "dmic-card"; simple-audio-card,format = "pdm"; status = "okay"; simple-audio-card,dai-link@0 { cpu { sound-dai = <&dmic>; }; codec { sound-dai = <&dmic_codec>; }; }; }; dmic_codec: dmic_codec { #sound-dai-cells = <0>; compatible = "linux,dmic-codec"; }; and created a small patch to allow the generic dmic-hifi codec to be instantiated from device tree. diff --git a/sound/soc/codecs/dmic.c b/sound/soc/codecs/dmic.c index fde5325..67b9198 100644 --- a/sound/soc/codecs/dmic.c +++ b/sound/soc/codecs/dmic.c @@ -69,11 +69,18 @@ static int dmic_dev_remove(struct platform_device *pdev) return 0; } -MODULE_ALIAS("platform:dmic-codec"); +#ifdef CONFIG_OF +static const struct of_device_id dmic_dt_ids[] = { + { .compatible = "linux,dmic-codec", }, + { } +}; +MODULE_DEVICE_TABLE(of, dmic_dt_ids); +#endif static struct platform_driver dmic_driver = { .driver = { .name = "dmic-codec", + .of_match_table = of_match_ptr(dmic_dt_ids), }, .probe = dmic_dev_probe, .remove = dmic_dev_remove, @@ -81,6 +88,7 @@ static struct platform_driver dmic_driver = { module_platform_driver(dmic_driver); +MODULE_ALIAS("platform:dmic-codec"); MODULE_DESCRIPTION("Generic DMIC driver"); MODULE_AUTHOR("Liam Girdwood <lrg(a)slimlogic.co.uk>"); MODULE_LICENSE("GPL"); However, no soundcards get loaded, and I don't get error or warnings in dmesg, so I'm at a bit of a loss at where I'm going wrong. Can anybody see any glaring mistakes? I know the driver is definitely getting loaded as I have seen errors relating to me not specifying the sound-dai-cells from the simple-audio-card driver. Any ideas would be greatly recieved! Cheers,

[alsa-devel] [PATCH] ALSA: usb-audio: fix missing input volume controls in MAYA44 USB(+)
by Clemens Ladisch 03 Jun '15

03 Jun '15

The driver worked around an error in the MAYA44 USB(+)'s mixer unit descriptor by aborting before parsing the missing field. However, aborting parsing too early prevented parsing of the other units connected to this unit, so the capture mixer controls would be missing. Fix this by moving the check for this descriptor error after the parsing of the unit's input pins.

[alsa-devel] [PATCH 0/5] OMAPDSS: HDMI audio compliance fixes
by Jyri Sarha 03 Jun '15

03 Jun '15

I have rebased these patches from ti-linux-3.14.y on top of Linux 4.0.0. I tested them briefly on OMAP4 and OMAP5 in my environment, but I could not test any channel count beyond stereo. However, there were no conflicts in the rebase and each fix makes sense when looking at the chip TRM and the relevant HDMI specs. All the changes are really minor, but most of them apply to OMAPDSS side, so it is probably best to merge them trough there. Best regards, Jyri Misael Lopez Cruz (5): OMAPDSS: HDMI4: Set correct CC for 8-channels layout OMAPDSS: HDMI5: Set valid sample order OMAPDSS: HDMI5: Fix AUDICONF3 bitfield offsets ASoC: omap-hdmi-audio: Force channel allocation only for OMAP4 ASoC: omap-hdmi-audio: Fix invalid combination of DM_INH and CA drivers/video/fbdev/omap2/dss/hdmi4_core.c | 12 +++++++++++- drivers/video/fbdev/omap2/dss/hdmi5_core.c | 5 ++++- sound/soc/omap/omap-hdmi-audio.c | 12 +++++++----- 3 files changed, 22 insertions(+), 7 deletions(-) -- 1.9.1

[alsa-devel] [PATCH v2] ASoC: qcom: Remove QCOM dependency from LPASS variants
by Kenneth Westfield 03 Jun '15

03 Jun '15

From: Kenneth Westfield <kwestfie(a)codeaurora.org> Building with the following config options ... CONFIG_COMPILE_TEST=y # CONFIG_SND_SOC_QCOM is not set CONFIG_SND_SOC_LPASS_IPQ806X=m CONFIG_SND_SOC_STORM=m ... causes the following build warning: warning: (SND_SOC_STORM) selects SND_SOC_LPASS_IPQ806X which has unmet direct dependencies (SOUND && !M68K && !UML && SND && SND_SOC && SND_SOC_QCOM) To fix this, the dependency on SND_SOC_QCOM from the user-invisible LPASS variant config options has been removed. This will allow for successful randconfig builds that use COMPILE_TEST.

[alsa-devel] [PATCH v4 0/3] ASoC: qcom: add support to apq8016 audio
by Srinivas Kandagatla 03 Jun '15

03 Jun '15

Hi Mark, Thanks for applying the patches. Am resending the leftover patches rebased on top of topic/qcom branch. I have funtionally tested these patches on AP8016-SBC board and also compile tested them without CONFIG_OF on x86 to make sure nothing breaks. All these patches are tested and Acked. I Also included Arnd's Patch to fix Kconfig dependency on STORM board. APQ8016 has 4 MI2S( Primary, Secondary, Tertiary, Quaternary) which can be routed to internal wcd codec or external codecs. This routing is controlled by 2 mux registers. Changes since v3 - dropped OF dependency patch - dropped 6 patches which are already applied by Mark. - fixed Kconfig as suggested by Arnd. Changes since v2(https://lkml.org/lkml/2015/5/16/236) - dropped 3 patches which are already applied by Mark. - rebased on top of topic/qcom branch. - changed dev_err to dev_warn spotted by Kenneth. - fixed typo spotted by kenneth. Changes since v1(https://lwn.net/Articles/644266/) - Fixed Kconfig dependencies spotted by Kenneth - Fixed compilation error on ipq806x spotted by Kenneth - Fixed clk error messages spotted by Kenneth Changes since RFC(https://lwn.net/Articles/642661/) - droped cleanup patches, as they are already applied by Mark. - prefixed shared functions with asoc_qcom_* as suggested by Kenneth - made LPASS driver depended on OF. - removed ipq806x specific bits from ipaif_reg.h - removed no_osr clk flag as suggested by Mark and Kenneth - fixed irq return values spotted by Kenneth - renamed the machine file to apq8016-sbc.c as suggested by Kenneth. - use dai->driver->id instead of dai->id as it breaks on Storm board. --srini Arnd Bergmann (1): ASoC: qcom: fix STORM board Kconfig Srinivas Kandagatla (2): ASoC: qcom: Add apq8016 lpass driver support ASoC: qcom: add apq8016 sound card support include/dt-bindings/sound/apq8016-lpass.h | 9 ++ sound/soc/qcom/Kconfig | 17 ++- sound/soc/qcom/Makefile | 4 + sound/soc/qcom/apq8016_sbc.c | 215 ++++++++++++++++++++++++++ sound/soc/qcom/lpass-apq8016.c | 242 ++++++++++++++++++++++++++++++ sound/soc/qcom/lpass.h | 4 + 6 files changed, 490 insertions(+), 1 deletion(-) create mode 100644 include/dt-bindings/sound/apq8016-lpass.h create mode 100644 sound/soc/qcom/apq8016_sbc.c create mode 100644 sound/soc/qcom/lpass-apq8016.c -- 1.9.1

[alsa-devel] [ALSA-UTILS][PATCH] Add support for cplay and crecord
by Qais Yousef 03 Jun '15

03 Jun '15

cplay and crecord use compress offload API to play and record compressed audio. They're based on cplay and crec from tinycompress library using LGPL license. For now cplay only supports playing mp3 files. Signed-off-by: Qais Yousef <qais.yousef(a)imgtec.com> Cc: Takashi Iwai <tiwai(a)suse.de> Cc: Vinod Koul <vinod.koul(a)intel.com> Cc: Mark Brown <broonie(a)kernel.org> --- I renamed crec to crecord also to match aplay and arecord, hopefully you don't mind Vinod. This patch is dependent on my other patch that adds support for compress offload to alsa-lib. I needed to include <sound/compress_params.h> in cplay.c and crec.c but I couldn't find an example of any C file which directly includes <sound/*.h> The norm seems to be to just include <alsa/asoundlib.h>. Do I need to redefine structs from <sound/compress_params.h> to newly added <alsa/compress.h>? <alsa/pcm.h> seems to redefine structs from <sound/asound.h>. I could only test cplay but have no means to test crecord at the moment.

So the controller flag 'need_i915_power' is not set to release the display power after probe, and the codec flag 'link_power_control" is set to request/release the display power via bus link_power ops.

[alsa-devel] [PATCH 0/4] new fix for broadwell module removing failed issue
by Jie Yang 03 Jun '15

03 Jun '15

This patch series are based on broonie/sound.git for-next branch, commit 01a4d5083562fcdeab99d42b0873aabc5fcca018. The broadwell platform driver had module removing failed issue, and the two commits("ASoC: Intel: remove unused function hsw_pcm_free_modules()" and "ASoC: Intel: fix broadwell module removing failed issue") workaround it. But at the same time, we shouldn't leave the device as suspended state after module freed, it is not good to do runtime suspend at driver free either, so the fix was workaround only and not good enough. Here revert the old fix, and replace it with new unified procedure for runtime modules freeing: suspends firmware ==> frees runtime modules ==> unloads firmware. With this new procedure, we remove the runtime modules at both runtime suspend(D0->D3) and module(snd_soc_sst_haswell_pcm) removing, but make sure we do it only once. Jie Yang (4): Revert "ASoC: Intel: remove unused function hsw_pcm_free_modules()" Revert "ASoC: Intel: fix broadwell module removing failed issue" ASoC: Intel: check and clear runtime module pointer ASoC: Intel: handle haswell pcm suspend including runtime modules freeing sound/soc/intel/haswell/sst-haswell-pcm.c | 46 +++++++++++++++++++++++++------ 1 file changed, 37 insertions(+), 9 deletions(-) -- 1.9.1

[alsa-devel] [PATCH] ASoC: wm8731: initialize the hardware when loading the codec driver; use regmap for I/O
by Sergey Kiselev 02 Jun '15

02 Jun '15

Hi, This patch moves the request supplies and hardware reset and initialization from wm8731_probe to wm8731_i2c_probe and wm8731_spi_probe. So that the codec hardware is initialized when loading the codec driver, and not when loading the machine driver. The I/O is converted to regmap_write and regmap_update_bits. (Mostly as a side effect, since snd_soc_write and friends won't work before snd_soc_register_codec is called) Signed-off-by: Sergey Kiselev <sergey.kiselev(a)intel.com> --- wm8731.c | 107 ++++++++++++++++++++++++++++++++++++++++++--------------------- 1 file changed, 72 insertions(+), 35 deletions(-) diff --git a/sound/soc/codecs/wm8731.c b/sound/soc/codecs/wm8731.c index 2245b6a..05fa4d6 100644 --- a/sound/soc/codecs/wm8731.c +++ b/sound/soc/codecs/wm8731.c @@ -84,7 +84,7 @@ static bool wm8731_writeable(struct device *dev, unsigned int reg) return reg <= WM8731_RESET;

[alsa-devel] [PATCH v8 1/4] ASoC: arizona: Export functions to control subsystem DVFS
by Richard Fitzgerald 02 Jun '15

02 Jun '15

The WM5102 and WM8997 codecs have an internal dynamic clock booster. When this booster is active, the DCVDD voltage must be increased. If all the currently active audio paths can run with the root SYSCLK we can disable the booster, allowing us to turn down DCVDD voltage to save power. Previously this was being done by having the booster enable bit set as a side-effect of the LDO1 regulator driver, which is unexpected behaviour of a regulator and not compatible with using an external regulator. This patch exports functions to handle the booster enable and DCVDD voltage, with each relevant subsystem flagging whether it can currently run without the booster. Note that these subsystems are stateless and none of them are nestable, so there's no need for reference counting, we only need a simple boolean for each subsystem of whether their current condition could require the booster or will allow us to turn the codec down to lower operating power.

[alsa-devel] [PATCH v2] ASoC: davinci-mcasp: Choose PCM driver based on configured DMA controller
by Jyri Sarha 02 Jun '15

02 Jun '15

Find the configured DMA controller by asking for a DMA channel in the probe phase and releasing it right after. The controller device can be found via the dma_chan struct and the controller is recognized from the compatible property of its device node. The patch assumes EDMA if there is no device node.

[alsa-devel] [WM5102/ARIZONA] spi driver needs to support ACPI
by Christian Hartmann 02 Jun '15

Hi list, I need ACPI support for the arizona-core / arizona-spi driver for the ACPI ID WM5102. This audio codec is build into the Lenovo Yoga 851F. This device is a 32Bit (UEFI) system http://support.lenovo.com/de/de/products/tablets/yoga-series/yoga-tablet-2-… I have tested with vanilla kernels from kernel.org 3.19.y ,4.0.y and master (from torvalds) currently its 4.1.0-rc3.

[alsa-devel] [PATCH v4 0/7] ASoC: intel - add skylake PCM driver
by Vinod Koul 02 Jun '15

02 Jun '15

SKL has HDA controller based audio subsystem with DSP and support for I2S, HDA, PDM links. The hda core code has been moved to sound/hda/ by Takashi which current HDA drivers use and will also be used by ASoC SKL driver. The SKL platform driver will load and create the soc_hdac_bus which embeds the hdac_bus, same for hdac_device (hda codecs) and hdac_stream (pcms) This is on top of hdac code in Takashi's topic/hda This patch provides the match function for asoc type hda codecs and let's them get enumerated by hdac. The second patch in this series adds the controller specific soc code. Common parts are in hdac core with changes introduced as part of SKL controller in soc part. Then we add the rest of controller PCM driver code (still HDA) and last patch breaks the HDA streams to host and link which will allow insertion of DSP in between these links. The subsequent series will add IPC driver for SKL (using common IPC routines), then DSP topology handlers, DSP code with I2S support and then lastly when DFW is accepted then its handlers. This patch series adds the hda codec match functions followed by asoc hda controller routines, then SKL PCM driver and last decouples the controller for splitting the links Fixes in v4: Updates changelog in patch1 and few other patches Address Takashi's comment Address Marks comments Jeeja KP (7): ASoC: hda - add ASoC HDA codec match function ALSA: hda - add new HDA registers ASoC: hda - add asoc hda core bus, controller and stream helpers ASoC: intel - add Skylake HDA platform driver ASoC: intel - add Skylake HDA audio driver ASoC: intel - add makefile support for SKL driver ASoC: intel - adds support for decoupled mode in skl driver include/sound/hda_register.h | 88 ++++ include/sound/soc-hda-codec.h | 49 ++ include/sound/soc-hdaudio.h | 360 +++++++++++++ sound/soc/Kconfig | 1 + sound/soc/Makefile | 1 + sound/soc/hda/Kconfig | 3 + sound/soc/hda/Makefile | 4 + sound/soc/hda/soc-hda-codec.c | 89 ++++ sound/soc/hda/soc-hdac-bus.c | 115 +++++ sound/soc/hda/soc-hdac-controller.c | 296 +++++++++++ sound/soc/hda/soc-hdac-stream.c | 409 +++++++++++++++ sound/soc/intel/Kconfig | 17 + sound/soc/intel/Makefile | 1 + sound/soc/intel/skylake/Makefile | 3 + sound/soc/intel/skylake/hda-skl-pcm.c | 937 ++++++++++++++++++++++++++++++++++ sound/soc/intel/skylake/hda-skl.c | 670 ++++++++++++++++++++++++ sound/soc/intel/skylake/hda-skl.h | 74 +++ 17 files changed, 3117 insertions(+) create mode 100644 include/sound/soc-hda-codec.h create mode 100644 include/sound/soc-hdaudio.h create mode 100644 sound/soc/hda/Kconfig create mode 100644 sound/soc/hda/Makefile create mode 100644 sound/soc/hda/soc-hda-codec.c create mode 100644 sound/soc/hda/soc-hdac-bus.c create mode 100644 sound/soc/hda/soc-hdac-controller.c create mode 100644 sound/soc/hda/soc-hdac-stream.c create mode 100644 sound/soc/intel/skylake/Makefile create mode 100644 sound/soc/intel/skylake/hda-skl-pcm.c create mode 100644 sound/soc/intel/skylake/hda-skl.c create mode 100644 sound/soc/intel/skylake/hda-skl.h -- 1.9.1

[alsa-devel] ASoC: PATCH: wm8731 - reinitialize regmap cache after hardware reset
by Sergey Kiselev 02 Jun '15

02 Jun '15

Hi, I am working on a machine driver that uses wm8731 codec and I've noticed that it will not work after rmmod/modprobe of that machine driver. The issue is that wm8731_probe() resets the hardware, but it doesn't reinitialize the regmap cache to the default values. The patch below fixes this issue. I also skimmed through other codecs, and some of them might have similar issue (wm8510.c, wm8711.c, wm8750.c, wm8753.c, wm8940.c, wm8960.c, wm8971.c, wm8974.c, wm8988.c, wm8990.c) Another way to avoid this issue might be resetting the codec in the *_spi_probe()/*_i2c_probe(), so that it only gets reset once when codec is loading.

[alsa-devel] [PATCH] ASoC: davinci-mcasp: Choose PCM driver based on configured DMA controller
by Jyri Sarha 02 Jun '15

02 Jun '15

Find the configured DMA controller by asking for a DMA channel in the probe phase and releasing it right after. The controller device can be found via the dma_chan struct and the controller is recognized from the compatible property of its device node. The patch assumes EDMA if there is no device node.

With this patchset I tried to modernise and restructure the LoCoMo drivers. * Use platform bus and mfd core code * Use GPIO API instead of custom locomo GPIO code * Use irqdomains to manage IRQs * Split mixed locomolcd driver to lcd and backlight parts * Implement IRQ handling in GPIO driver * Implement SPI driver used as a host for mmc_spi device to control SD cards Changes since v3: * Removed magic values in locomo irq handling code * Using mutex in locomokbd driver * Dropped empty locomokbd_remove * Small rearrangement of headers/comments/etc in core and input drivers The following changes since commit b787f68c36d49bb1d9236f403813641efa74a031: Linux 4.1-rc1 (2015-04-26 17:59:10 -0700) are available in the git repository at: git://git.infradead.org/users/dbaryshkov/zaurus.git locomo-v4 for you to fetch changes up to 7c8e8e05ca27a4ad82356eb57ad12a7ca39bfd95: ARM: drop old LoCoMo driver (2015-05-25 14:29:23 +0300) ---------------------------------------------------------------- Dmitry Eremin-Solenikov (18): mfd: add new driver for Sharp LoCoMo leds: port locomo leds driver to new locomo core input: convert LoCoMo keyboard driver to use new locomo core input: locomokbd: differentiate between two Enter keys input: make LoCoMo keyboard driver support both poodle and collie video: backlight: add new locomo backlight driver video: lcd: add LoCoMo LCD driver gpio: port LoCoMo gpio support from old driver gpio: locomo: implement per-pin irq handling spi: add locomo SPI driver i2c: add locomo i2c driver ARM: sa1100: make collie use new locomo drivers ARM: sa1100: don't preallocate IRQ space for locomo ASoC: pxa: poodle: make use of new locomo GPIO interface ARM: pxa: poodle: use new LoCoMo driver ARM: pxa: poodle: don't preallocate IRQ space for locomo video: backlight: drop old locomo bl/lcd driver ARM: drop old LoCoMo driver arch/arm/common/Kconfig | 3 - arch/arm/common/Makefile | 1 - arch/arm/common/locomo.c | 914 ----------------------------- arch/arm/include/asm/hardware/locomo.h | 221 ------- arch/arm/mach-pxa/Kconfig | 1 - arch/arm/mach-pxa/include/mach/poodle.h | 8 +- arch/arm/mach-pxa/poodle.c | 58 +- arch/arm/mach-sa1100/Kconfig | 1 - arch/arm/mach-sa1100/collie.c | 213 +++++-- arch/arm/mach-sa1100/include/mach/collie.h | 16 +- arch/arm/mach-sa1100/include/mach/irqs.h | 19 +- drivers/gpio/Kconfig | 13 + drivers/gpio/Makefile | 1 + drivers/gpio/gpio-locomo.c | 285 +++++++++ drivers/i2c/busses/Kconfig | 12 + drivers/i2c/busses/Makefile | 1 + drivers/i2c/busses/i2c-locomo.c | 135 +++++ drivers/input/keyboard/Kconfig | 2 +- drivers/input/keyboard/locomokbd.c | 262 ++++----- drivers/leds/Kconfig | 2 +- drivers/leds/leds-locomo.c | 117 ++-- drivers/mfd/Kconfig | 10 + drivers/mfd/Makefile | 1 + drivers/mfd/locomo.c | 336 +++++++++++ drivers/spi/Kconfig | 10 + drivers/spi/Makefile | 1 + drivers/spi/spi-locomo.c | 332 +++++++++++ drivers/video/backlight/Kconfig | 16 +- drivers/video/backlight/Makefile | 3 +- drivers/video/backlight/locomo_bl.c | 153 +++++ drivers/video/backlight/locomo_lcd.c | 285 +++++++++ drivers/video/backlight/locomolcd.c | 255 -------- include/linux/mfd/locomo.h | 169 ++++++ sound/soc/pxa/poodle.c | 52 +- 34 files changed, 2205 insertions(+), 1703 deletions(-) delete mode 100644 arch/arm/common/locomo.c delete mode 100644 arch/arm/include/asm/hardware/locomo.h create mode 100644 drivers/gpio/gpio-locomo.c create mode 100644 drivers/i2c/busses/i2c-locomo.c create mode 100644 drivers/mfd/locomo.c create mode 100644 drivers/spi/spi-locomo.c create mode 100644 drivers/video/backlight/locomo_bl.c create mode 100644 drivers/video/backlight/locomo_lcd.c delete mode 100644 drivers/video/backlight/locomolcd.c create mode 100644 include/linux/mfd/locomo.h

[alsa-devel] [PATCH v7 1/4] ASoC: arizona: Export functions to control subsystem DVFS
by Richard Fitzgerald 02 Jun '15

02 Jun '15

The WM5102 and WM8997 codecs have an internal dynamic clock booster. When this booster is active, the DCVDD voltage must be increased. If all the currently active audio paths can run with the root SYSCLK we can disable the booster, allowing us to turn down DCVDD voltage to save power. Previously this was being done by having the booster enable bit set as a side-effect of the LDO1 regulator driver, which is unexpected behaviour of a regulator and not compatible with using an external regulator. This patch exports functions to handle the booster enable and DCVDD voltage, with each relevant subsystem flagging whether it can currently run without the booster. Note that these subsystems are stateless and none of them are nestable, so there's no need for reference counting, we only need a simple boolean for each subsystem of whether their current condition could require the booster or will allow us to turn the codec down to lower operating power.

Nothing in asm/io.h uses anything from vmalloc.h, so remove the include and fix up the build problems in an allmodconfig (64 bit and 32 bit) build. This may be the place where x86 builds get vmalloc.h implicitly included and that tends to hide places where vmalloc() et al are added to files but the include of vmalloc.h is forgotten.

[alsa-devel] [PATCH 0/2] Update ALSA driver to use media controller API
by Shuah Khan 01 Jun '15

01 Jun '15

This patch series updates ALSA driver to use media controller API to share tuner with DVB and V4L2 drivers that control AU0828 media device. Two new interfaces are added to media controller API to enable creating media device as a device resource. This allows creating media device as a device resource on the main struct device that is common to all drivers that control a single media hardware and share resources on it. Drivers then can find the common media device to register entities and manage links, and pipelines. Tested with and without CONFIG_MEDIA_CONTROLLER enabled. Tested tuner entity doesn't exist case as au0828 v4l2 driver is the one that will create the tuner when it gets updated to use media controller API. Please note that au0828 updates media controller are necessary before the resource sharing can work across ALSA and au0828 dvb and v4l2 drivers. This work is in progress and another developer is working on it.

[alsa-devel] Override default behavior when headphones are connected upon user request on wm8962
by Santiago Zarate 01 Jun '15

01 Jun '15

Hello, Currently i'm trying to override the default behavior when headphones are plugged, We actually need to play audio under certain situations, and one of the use cases is when the headphones are connected, but a sound needs to be played over the speakers, so someone else is aware of what's happening. We're thinking about using a GPIO that it's available from our application or a simple module parameter, but the problem i'm facing right now is: 1: Where to specify that particular path or the behavior i need, i've been looking at [2], and adding a SOC_DAPM_PIN_SWITCH[1] but doesn't matter what the state is, if the headphones are on, i can't turn on the speakers to play sounds at the same time. i'm able to do it, by disabling the hp detection pin, and controlling the audio over udev events. so i'm pretty sure that it would be possible to do this, with the hp detection pin. which takes us to #2: 2: How can i trigger an event based on the change of a module parameter or a gpio port (Thinking both would be the same)... i've tried to alter hp_event <http://lxr.free-electrons.com/ident?v=3.16;i=hp_event> without any success... even returning 0 on any event and still nothing, which drives me to belive that i'm doing something completely wrong AND the codec/driver is among the last ones to get notified of the presence of the hp The idea is: if override port or parameter is set to true, trigger the audio override and play sound on Speaker and HP at the same time. right now i'm working with imx-wm8962 driver and the matching codec, http://mailman.alsa-project.org/pipermail/alsa-devel/2011-February/036370.h… [1] http://mailman.alsa-project.org/pipermail/alsa-devel/2010-December/035055.h… [2] Thanks in advance! -- Santiago Zarate http://foursixnine.io “Dreams permit each and every one of us to be quietly and safely insane every night of our lives.” - William Dement

[alsa-devel] Audio play problem with tlv320aic3106 in mainline.
by Enric Balletbo Serra 01 Jun '15

01 Jun '15

Dear all, Recently I sent some patches to add support for a new board based on AM335x processor [1]. The board has the TLV320AIC3106 audio codec, the MCLK signal is provided by an external oscillator of 12MHz. The problem is that when I play a wav file for example I heard the song a double speed. This is with v4.0 and current mainline. In dts file I defined "ti,codec-clock-rate = <12000000>;" which is the correct value. Curiously when I changed the clock rate value to 24000000 I heard the song at normal speed. AFAIK the correct value for clock-rate is 12MHz so I suspect that something is wrong in the driver, maybe it sets a wrong clock divider/multiplier ? Anyone can point me in the right direction to fix the issue ? I see that am335x-evm and am335x-pepper boards also uses this audio codec, did anyone with those boards have the same problem? [1] https://patchwork.kernel.org/patch/6480071/ Thanks in advance, Enric

[alsa-devel] [RFC] sound: ppc: keywest: check if DEQ was already instantiated
by Wolfram Sang 01 Jun '15

01 Jun '15

Due to changes in i2c-powermac, for some Macs the DEQ is instantiated now in i2c-powermac while some need the instantiation here in the keywest sound driver. The proper fix is to convert this driver to AOA. Until then support both ways of instantiation. Before this patch, some Macs lost sound because the sound driver failed when instantiating the DEQ for the second time. Signed-off-by: Wolfram Sang <wsa(a)the-dreams.de> --- Dan, Mark: I hope I found a generic but not too intrusive solution to the doubled instantiation problem.

by Takashi Sakamoto 30 May '15

30 May '15

Hi, This patchset adds a validator for dimen field in control element information. The dimen information is used to represent channel matrix of the control element, thus the number of elements in the matrix should be within the number of channels in the control element. Current implementation allows each drivers to set arbitrary number to the information. When the information is wrong, it can cause buffer-over-run to userspace applications depending on application implementation. Actually, the dimen information is scarcely used by current drivers and applications, while it's better for ALSA core to ensure the information is enough safe.

[alsa-devel] [PATCH v3 0/3] ASoC topology
by Liam Girdwood 29 May '15

29 May '15

ASoC topology (formerly called dynamic firmware) allows audio DSP topology to be defined as part of the firmware package and not hard coded into the driver. This allows DSP vendors to ship multiple different firmwares or firmwares with programmable topologies for different devices (i.e. phones, tablets, TVs) using a single DSP driver. The DSP topology can be contained as part of the firmware file or exist as separate files. The topology core and file format is generic text and not tied to any single vendor or device. The topology core consists of kernel and userspace components :- Kernel. The kernel core reads in the topology data and builds the driver capabilities and audio topology based on this data. This includes building the DAPM graph, setting PCM and DAI capabilities, registering kcontrols and registering DAPM widgets. The userspace tool allows the creation of binary DSP FW topology files based on a topology text files. The tool is temporarily available on github and its intended to be merged into the alsa-utils package after a clean up. https://github.com/lgirdwood/topology.git Changes since V2 :- o Moved TLV channel maps into TLV UAPI header. o Report error in logs when no handler exists for vendor data types. o Fix comments on kcontrol/widget ops to match core code. Changes since RFC :- o Fixed patch series to survive bisection builds. o Removed widget ID enum from UAPI. o Added channel mappings to controls. o Added TLV macro patch to UAPI. o Fixed locking for runtime and init time topology loading. o Moved the UAPI group index field to the block header. Changes since V1 (back in 2012) :- o Name changed to ASoC Topology o Structures from soc.h and soc-dapm.h no longer exposed as UAPIs o Moved to component model from codec/platform model. o Added reserved fields in each UAPI structure. o UAPI structures packed and endianess defined for each structure. o Added support for PCM, DAI and codec <-> codec link capabilities. o Added support for client drivers manifests. o Added support for private data for each dynamic object type. o Single list of dynamic objects rather than list of each object type.

[alsa-devel] [PATCH] ALSA: jack: Fix the id uniqueness check

29 May '15

snd_kctl_jack_new() tries to assign a unique index number when a name string that has been already registered is passed.

[alsa-devel] [PATCH] ALSA: hda - Set patch_ops before calling auto-parser
by Takashi Iwai 29 May '15

29 May '15

... so that the parser code can overwrite some optional ops. For Realtek and others, it can be set solely in the spec allocator, so it results in a good code cleanup, too. With this change, we can finally remove the local stream_pm setup and rely on the generic parser's automatic setting.

[alsa-devel] [PATCH] ASoC: DAPM: Add APIs to create individual DAPM controls.
by Liam Girdwood 29 May '15

29 May '15

The topology core needs to be able to create individual widget controls at runtime and driver init. Add a regular locked and unlocked API calls to facilitate this requirement. The unlocked call is used by the topology core during component driver probing where the card dapm_mutex is held by the ASoC core and the locked version at non component driver probe time.

[alsa-devel] [PATCH] ALSA: fix building with CONFIG_SND_PROC_FS disabled
by Arnd Bergmann 29 May '15

29 May '15

A recent change to split the procfs support for ALSA turned out to be incomplete, leading to build errors: sound/core/seq/seq_info.c:61:12: error: redefinition of 'snd_seq_info_init' sound/core/seq/seq_device.c: In function 'seq_dev_proc_init': sound/core/seq/seq_device.c:276:2: error: 'info_entry' undeclared (first use in this function) sound/core/seq/seq_device.c: In function 'alsa_seq_device_exit': sound/core/seq/seq_device.c:309:22: error: 'info_entry' undeclared (first use in this function) This replaces some more instances of CONFIG_PROC_FS with CONFIG_SND_PROC_FS, as the original patch started. It is enough to avoid all randconfig regressions I saw on ARM because of the CONFIG_SND_PROC_FS introduction.

[alsa-devel] ASoC: codec register dump in debugfs
by Sergej Sawazki 29 May '15

29 May '15

Dear all, please correct me if I am wrong. Since the codec drivers have been converted to direct regmap API usage, it is not common to set the following snd_soc_codec_driver struct members: .reg_cache_size .reg_word_size However, the functions soc_codec_reg_show() and format_register_str() (responsible for formating and printing the codec register dumps to debugfs) depend on these members. I'm writing a ASoC machine driver. The board has two wm8741 codecs. I would like to see the codec register dumps in debugfs. eg: cat /sys/kernel/debug/asoc/<card_name>/codec\:wm8741.1-001a/codec_reg cat /sys/kernel/debug/asoc/<card_name>/codec\:wm8741.1-001b/codec_reg Is it OK to set the above mentioned members in a codec driver to "enable" the register dump output? Or should we refactor the above mentioned functions to use the regmap API? Or am I missing something? Thanks, Sergej

Takashi, all, On several of my machines there is no longer any sound output when running the latest linux-next (20150528). Activity can be seen in a mixer such as pavucontrol suggesting that there should be sound, but both the speakers and head phones are silent. I have bisected the kernel and found that the following patch introduced the bug.

[alsa-devel] [PATCH v2 1/3] ASoC: topology: Add topology UAPI header
by Liam Girdwood 29 May '15

29 May '15

The ASoC topology UAPI header defines the structures required to define any DSP firmware audio topology and control objects from userspace. The following objects are supported :- o kcontrols including TLV controls. o DAPM widgets and graph elements o Vendor bespoke objects. o Coefficient data o FE PCM capabilities and config. o BE link capabilities and config. o Codec <-> codec link capabilities and config. o Topology object manifest. The file format is simple and divided into blocks for each object type and each block has a header that defines it's size and type. Blocks can be in any order of type and can either all be in a single file or spread across more than one file. Blocks also have a group identifier ID so that they can be loaded and unloaded by ID.

[alsa-devel] [RFC 0/5] Add a gpio jack device
by Dylan Reid 28 May '15

28 May '15

The first three changes add a gpio audio jack device. This device can be used on systems that report headphone or mic plug through GPIOS. There can be 0-N of these devices created per board each can report one of several events. For example, this allows for a single jack for HP/Mic and a separate jack for line out. The last two patches are an example of the jack being used on Acer's Tegra Chromebook, those can be considered separately and might not be worth the churn.

[alsa-devel] [PATCH] ALSA: hda - Disable Headphone Mic boost for ALC662
by David Henningsson 28 May '15

When headphone mic boost is above zero, some 10 - 20 second delay might occur before the headphone mic is operational. Therefore disable the headphone mic boost control (recording gain is sufficient even without it). (Note: this patch is not about the headset mic, it's about the less common mic-in only mode.)

[alsa-devel] Freescale iMX6SL SSI (I2S master mode) Rising edge vs Falling edge
by Xuebing Wang 28 May '15

28 May '15

Nicolin and alsa-devel community: Source code in fsl_ssi.c shows below in function fsl_ssi_set_dai_fmt(): ----------- switch (fmt & SND_SOC_DAIFMT_FORMAT_MASK) { case SND_SOC_DAIFMT_I2S: ... ... /* Data on rising edge of bclk, frame low, 1clk before data */ strcr |= CCSR_SSI_STCR_TFSI | CCSR_SSI_STCR_TSCKP | CCSR_SSI_STCR_TXBIT0 | CCSR_SSI_STCR_TEFS; break; ----------- According to iMX6SL reference manual, 'TSCKP = 1' means "Data clocked out on *falling* edge of bit clock." (for I2S master mode), rather than "Data on rising edge of bclk in the comments". This means this comment in the source code is *partially* WRONG, am I correct? However, RSCKP is = 1 (for receiving), it means "Data latched on rising edge of bit clock", which is correct. Also, I am not sure why there is inconsistency in iMX6SL reference manual (48.9 SSI Memory Map/Register Definition), that TSCKP = 1 (for transmitting) is FALLING_EDGE, but RSCKP = 1 (for receiving) is RISING_EDGE. Note: SSI (I2S master mode) works perfect on my hardware, I did not observe anything wrong. Thanks. -- Xuebing

[alsa-devel] [RFC v2 0/13] dw_hdmi cleanups, audio preparation, helpers and ahb audio support
by Russell King - ARM Linux 28 May '15

28 May '15

I'm sending this series for comments, and to allow people to update their code bases (for those who are using my AHB audio driver on iMX6). This is really several series, and I'm not expecting this to be ready for the upcoming merge window. That said, if anyone wants to say that they're happy with some of the initial six patches, I'm happy to queue those for David, if he's willing to take them. This series applies on top of my previous series, with the three patches from the rockchip guys applied, iow: drm: rockchip/dw_hdmi-rockchip: improve for HDMI electrical test drm: bridge/dw_hdmi: separate VLEVCTRL settting into platform driver drm: bridge/dw_hdmi: fixed codec style drm: bridge/dw_hdmi: adjust n/cts setting order drm: bridge/dw_hdmi: protect n/cts setting with a mutex drm: bridge/dw_hdmi: combine hdmi_set_clock_regenerator_n() and hdmi_regenerate_cts() The first four patches are a few cleanups to the dw_hdmi driver. The next two patches introduce new interfaces to the dw_hdmi driver to support AHB audio, including the errata found on iMX6 which requires N to be programmed to zero when the audio FIFO is not full. I'm expecting some discussion with these last two as we try to work out how to deal with the two variants of audio support for this part (AHB audio vs I2S audio). The following three add various helpers to the DRM and ALSA subsystems for audio support which is non-specific to the AHB audio driver. For DRM, this is a helper macro to obtain the pointer into the short audio descriptors. For ALSA, it's a set of helpers to restrict an audio PCM device's capabilities according to the ELD, and to generate the IEC958 channel status data. If these helpers are acceptable, we can convert a number of drivers to them. The ELD helper isn't quite finished, but should be sufficient for initial testing. The last two patches add support for the dw_hdmi audio. This is an ALSA driver rather than an ASoC driver as it's a pretty simple affair. I couldn't find a suitable location in the sound/ subtree to place it, so I've placed it next to the bridge - yes, we probably need to find it a better home in the sound/ subtree, but it currently makes use of dw_hdmi.h in the directory it lives. drivers/gpu/drm/bridge/Kconfig | 11 + drivers/gpu/drm/bridge/Makefile | 1 + drivers/gpu/drm/bridge/dw_hdmi-ahb-audio.c | 566 +++++++++++++++++++++++++++++ drivers/gpu/drm/bridge/dw_hdmi-ahb-audio.h | 14 + drivers/gpu/drm/bridge/dw_hdmi.c | 321 +++++++++------- drivers/gpu/drm/bridge/dw_hdmi.h | 3 + drivers/gpu/drm/imx/dw_hdmi-imx.c | 5 + include/drm/bridge/dw_hdmi.h | 7 + include/drm/drm_edid.h | 19 + include/sound/pcm_drm_eld.h | 6 + include/sound/pcm_iec958.h | 9 + sound/core/Kconfig | 6 + sound/core/Makefile | 2 + sound/core/pcm_drm_eld.c | 92 +++++ sound/core/pcm_iec958.c | 95 +++++ 15 files changed, 1029 insertions(+), 128 deletions(-) -- FTTC broadband for 0.8mile line: currently at 10.5Mbps down 400kbps up according to speedtest.net.

[alsa-devel] ASoC: regmap_config.max_register value wrong?
by Sergej Sawazki 27 May '15

27 May '15

Dear all, The following snippet is from the wm8741 codec driver. Shouldn't the .max_register field be set to WM8741_REGISTER_COUNT-1 (10) instead of WM8741_MAX_REGISTER (0x20)? [...] static const struct regmap_config wm8741_regmap = { .reg_bits = 7, .val_bits = 9, .max_register = WM8741_MAX_REGISTER, [...] WM8741_MAX_REGISTER is the address of the last register. WM8741_REGISTER_COUNT is the number of registers. The regmap_config documentation says: "@max_register: Optional, specifies the maximum valid register index." So it should be the *register index* and not the register address. Do I understand it correctly? Many thanks in advance. Best regards, Sergej

[alsa-devel] [PATCH] ALSA: firewire-lib: fix buffer-over-run when detecting packet discontinuity
by Takashi Sakamoto 27 May '15

27 May '15

When detecting packet discontinuity, handle_in_packet() returns minus value and this value is assigned to unsigned int variable, then the variable has huge value. As a result, the variable causes buffer-over-run in handle_out_packet(). This brings invalid page request and system hangup. This commit fixes the bug to add a new argument into handle_in_packet() and the number of handled data blocks is assignd to it. The function return value is just used to check error. I also considered to change the type of local variable to 'int' in in_stream_callback(). This idea is based on type-conversion in C standard, while it may cause future problems when adding more works. Thus, I dropped this idea.

27 May '15

A new AMD controller [1002:aac8] seems to need the quirk for other AMD NS HDMI stuff, otherwise it gives noisy sounds.

[alsa-devel] [PATCH RESEND v3 0/2] reducing memory footprint of ALSA
by Jie Yang 27 May '15

27 May '15

We are planning to work on reducing memory footprint of ALSA, targeting on small memory embedded devices(e.g. IoT), this series focuses on disabling procfs, hw/sw params refinement, mmap, dpcm, dapm, compressed API, compat code APIs... We plan to enable those reducing items only for EXPERT, and add knobs in sound/core/Kconfig. These first two patches is a start, adding SND_PROC_FS to config disable/enable ALSA proc FS, this disabling can save about 9KB code size on x86_64 platform. Changes in v3: 1. drop SND_REDUCED_MEMORY_FOOTPRINT and make configuration available only for EXPERT; 2. move the configure into sound/core/Kconfig; 3. Add missing Signed-off-by for PATCH 2/2. Changes in v2: 1. Prompt "Sound Proc FS Support" appears only when SND_REDUCED_MEMORY_FOOTPRINT is true.

[alsa-devel] [PATCH] ASoC: codecs: use SNDRV_PCM_FMTBIT_* for format bitmask
by Maciej S. Szmigiero 27 May '15

27 May '15

snd_soc_pcm_stream.formats is a bitmask of SNDRV_PCM_FMTBIT_*, not of SNDRV_PCM_FORMAT_* (which are sequential integers), however some of ASoC CODEC drivers use these values instead.

[alsa-devel] [PATCH v2] ASoC: Add GPIO based jack device
by Dylan Reid 27 May '15

27 May '15

Add a jack device that allows for separate headphone and mic detect GPIOs. This device will be used as an aux device and will registered the jack with the card at init time. The gpios are each optional allowing for a headphone, microphone, or combination devices to be created depending on the board configuration. A board will be able to have several of these jacks, one for each physical connection. Signed-off-by: Dylan Reid <dgreid(a)chromium.org> --- Tested on Acer Chromebook 13 Tegra device. I'm travelling this week, I'll try to get the rockchip team to integrate this with simple card for the 3288.

We are planning to work on reducing memory footprint of ALSA, targeting on small memory embedded devices(e.g. IoT), this series focuses on disabling procfs, hw/sw params refinement, mmap, dpcm, dapm, compressed API, compat code APIs... These first two patches is a start, add config menu in Kconfig, and disable ALSA proc FS once reducing memory footprint is selected, which can save about 9KB code size on x86_64 platform.

[alsa-devel] [PATCH v2 0/3] ASoC: topology
by Liam Girdwood 25 May '15

25 May '15

ASoC topology (formerly called dynamic firmware) allows audio DSP topology to be defined as part of the firmware package and not hard coded into the driver. This allows DSP vendors to ship multiple different firmwares or firmwares with programmable topologies for different devices (i.e. phones, tablets, TVs) using a single DSP driver. The DSP topology can be contained as part of the firmware file or exist as separate files. The topology core and file format is generic text and not tied to any single vendor or device. The topology core consists of kernel and userspace components :- Kernel. The kernel core reads in the topology data and builds the driver capabilities and audio topology based on this data. This includes building the DAPM graph, setting PCM and DAI capabilities, registering kcontrols and registering DAPM widgets. The userspace tool allows the creation of binary DSP FW topology files based on a topology text files. The tool is temporarily available on github and its intended to be merged into the alsa-utils package after a clean up. https://github.com/lgirdwood/topology.git Changes since RFC :- o Fixed patch series to survive bisection builds. o Removed widget ID enum from UAPI. o Added channel mappings to controls. o Added TLV macro patch to UAPI (should this be in asound.h ?). o Fixed locking for runtime and init time topology loading. o Moved the UAPI group index field to the block header. Changes since V1 (back in 2012) :- o Name changed to ASoC Topology o Structures from soc.h and soc-dapm.h no longer exposed as UAPIs o Moved to component model from codec/platform model. o Added reserved fields in each UAPI structure. o UAPI structures packed and endianess defined for each structure. o Added support for PCM, DAI and codec <-> codec link capabilities. o Added support for client drivers manifests. o Added support for private data for each dynamic object type. o Single list of dynamic objects rather than list of each object type.

[alsa-devel] ASoC: How to mix multi input ?
by Kuninori Morimoto 25 May '15

25 May '15

Hi Mark, ALSA SoC I would like to ask you how to mix multi input in ASoC. Renesas sound device(s) can mix multi input to 1 output. +-+ sound A --> |M| sound B --> |I| --> [ codec ] -> speaker sound C --> |X| +-+ Here, sound A/B/C will be used randomly. Does ALSA SoC already has this kind of system ? My image about these are like this. sound A: aplay -D hw:0 ... sound B: aplay -D hw:1 ... sound C: aplay -D hw:2 ... ... codec will be started if one of A/B/C are started, and it will be stopped if all of A/B/C are stopped.

Re: [alsa-devel] snd-bebob and PrismSound Orpheus fails with snd_pcm_hw_params_set_channels
by Mike Ood 24 May '15

24 May '15

Yet another experiment. Orpheus operation manual says there are six modes concerning Sync Source. -------------------------------------- Sync Source Master/Slave Description -------------------------------------- Local Master System is sync'ed to Orpheus' local clock Wordclock Master System is sync'ed to external wordclock applied to Orpheus DI Master System is sync'ed to external S/PDIF applied to Orpheus ADAT Master System is sync'ed to external ADAT (ADAT input must be enabled) PC DAW Slave Orpheus is slaved to system clock from host PC CSP Master System is sync'ed to Orpheus' 1394 clock (not recommended) -------------------------------------- With each of the five modes mentioned above (ADAT input not available), I tried to play music on Windows 7 using Audacity. The results are: ------------------- Local OK Wordclock NG DI NG PC DAW OK CSP OK ------------------- So it seems that if there is no external clock applied, when one is expected, Orpheus stops playing rather than trying to continue operation by free-running its clock. *** Takashi Sakamoto wrote: > Not funny, but headache.

I do not think I understand what you said here due to the lack of technical background, but what do you suggest at this moment to a casual applications programmer who wish to use snd-bebob with Orpheus? ------------ Answer 1 ------------ It should work. I received many successful reports for my final call for testing last year. It must be a hardware problem with your PC, or Firewire Cable, or Orpheus, or all of them. ------------ Answer 2 ------------ It should work. Check your software environment. Freshly installed Ubuntu 14.10 or later with the kernel 3.16 or later may not work. Always download the latest sources from GitHub, etc. ------------ Answer 3 ------------ Forget about snd-bebob, and fallback to libffado+jackd. The combination is loosing many packets, but if you say you do not notice any glitches, you should be completely happy with it. *** Regards, Mike Ood

[alsa-devel] [PATCH 1/3] ASoC: fsl_sai: add sai master mode support
by Zidan Wang 24 May '15

24 May '15

When sai works on master mode, set its bit clock and frame clock. SAI has 4 MCLK source, bus clock, MCLK1, MCLK2 and MCLK3. fsl_sai_set_bclk will select proper MCLK source, then calculate and set the bit clock divider. After fsl_sai_set_bclk, enable the selected mclk in hw_params(), and add hw_free() to disable the mclk.

It > handle audio dma based on soc-dmaengine > Mark, Do you have any comments on this patch set? Or you suggest to add HDMI API calling in the same serial patch? For the HDMI calling, I have no good idea except direct call currently. Because I need dts hook to audio driver, while no HDMI call back data can be shared from video side to audio side in this independent initialization case.

Sorry - the DT binding is normally before the code in the patch series. This is fine, it's just patch 1 that needs to be resolved then.

[alsa-devel] [PATCH v3 00/10] ASoC: qcom: add support to apq8016 audio
by Srinivas Kandagatla 22 May '15

22 May '15

Hi Mark, Am resending the the patches with rebased on top of topic/qcom branch. All these patches are tested and Acked. Thankyou for reviewing the v2 patches, here is the v3 patchset after incorporating review comments and testing on Storm Board. This patchset adds apq8016 audio support into lpass driver. Existing Lpass driver can not be used as-it-is for apq8016 as it contains code specific to ipq806x. Also the driver only supports single i2s port, single dma channel and single bitclk control. APQ8016 has 4 MI2S( Primary, Secondary, Tertiary, Quaternary) which can be routed to internal wcd codec or external codecs. This routing is controlled by 2 mux registers. This patch series firstly re-organizes the lpass driver such that the SOC specific bits are moved away from the driver. And secondly the SOC specifics are now passed as lpass variant data which would include various register offsets, dma channel allocations and SOC specific clock handling. Finally the last few patchs add apq8016 lpass and machine driver. All these patches are tested for HDMI audio via adv7533 bridge and Analog audio on APQ8016-SBC, msm8916-mtp boards and Kenneth tested this patchset on ipq806x Storm board too. Changes since v2(https://lkml.org/lkml/2015/5/16/236) - dropped 3 patches which are already applied by Mark. - rebased on top of topic/qcom branch. - changed dev_err to dev_warn spotted by Kenneth. - fixed typo spotted by kenneth. Changes since v1(https://lwn.net/Articles/644266/) - Fixed Kconfig dependencies spotted by Kenneth - Fixed compilation error on ipq806x spotted by Kenneth - Fixed clk error messages spotted by Kenneth Changes since RFC(https://lwn.net/Articles/642661/) - droped cleanup patches, as they are already applied by Mark. - prefixed shared functions with asoc_qcom_* as suggested by Kenneth - made LPASS driver depended on OF. - removed ipq806x specific bits from ipaif_reg.h - removed no_osr clk flag as suggested by Mark and Kenneth - fixed irq return values spotted by Kenneth - renamed the machine file to apq8016-sbc.c as suggested by Kenneth. - use dai->driver->id instead of dai->id as it breaks on Storm board. --srini Srinivas Kandagatla (10): ASoC: qcom: make lpass driver depend on OF ASoC: qcom: support bitclk and osrclk per i2s port ASoC: qcom: make osr clock optional ASoC: qcom: add dma channel control offset to variant data ASoC: qcom: Add ability to handle interrupts per dma channel ASoC: qcom: add bit map to track static dma channel allocations ASoC: qcom: Add apq8016 lpass driver support ASoC: qcom: add apq8016 sound card support ASoC: qcom: Document apq8016 bindings.

See dmaengine_pcm_set_runtime_hwparams().

[alsa-devel] how to ask you to write a new ALSA driver
by jean-noël chardron 22 May '15

22 May '15

hello, Last week I got a Komplet Audio 6 from Native intruments. The driver exist in ALSA driver for this king of interface audio (snd-usb-audio) (thanks for the team who write this) but for the model where Id Vendor is 0x17cc and Id product is 0x1000. The KA6 that I got has not the same ID product (0x1001) therefore I don't have any device capture even with the driver snd-usb-audio. The challenge is to write the modification for this new model. Who could do that ? If necessary I could send log, compile kernel source and so on. thanks, Jean-noel

[alsa-devel] [PATCH] ASoC: qcom: remove incorrect dependencies
by Arnd Bergmann 21 May '15

21 May '15

Compile-tests show a warning for the newly added SND_SOC_STORM symbol: warning: (SND_SOC_STORM) selects SND_SOC_LPASS_CPU which has unmet direct dependencies (SOUND && !M68K && !UML && SND && SND_SOC && SND_SOC_QCOM) The problem is that it can be selected for COMPILE_TEST on non-QCOM builds, but the symbols it selects have a dependency. Dropping the dependencies makes it work without warnings and no other side-effects, because these are not user-visible.

[alsa-devel] [PATCH] ASoC: skip legacy dai naming if dai driver has all the information
by Srinivas Kandagatla 21 May '15

21 May '15

Original issue is that the id field in the dai is not same as the id in dai_driver when dai driver count == 1. This is due to the legacy dai naming check, which could possibly cause issues if the audio drivers written in assumption that dai->id would be always equal to dai_driver->id. This assumption is true only if the dai driver count is greater than 1, and false if dai driver count is 1. On Qcom Lpass driver we hit such issue while adding support to apq8016. The code path which falls back to legacy naming for cases where num_dai == 1 does not check if there is any valid information in the dai_driver. This patch fixes that by checking if the dai_driver has valid id and name before falling back to legacy dai naming Although the drivers can work around this issue by only using dai->driver->id, but this patch attempts to fix the actual issue.

[alsa-devel] Assert in pcm_params.c
by Alan Horstmann 21 May '15

21 May '15

Hi, The following assert is being hit in pcm_params.c: "pcm_params.c:2249: snd1_pcm_hw_params_slave: Assertion `err >= 0' failed." This is from a developer using Portaudio in his own application; I have yet to ascertain full details, but it is trying successive sample rates to see which are valid. Does this point to a flaw in the configuration or possibly a bug in Alsa-lib or can it occur just as a result of misuse of the Alsa API? Regards Alan

[alsa-devel] [RFC PATCH 00/14] ASoC: qcom: add support to apq8016 audio
by Srinivas Kandagatla 21 May '15

21 May '15

Hi All, This patchset adds apq8016 audio support into lpass driver. Existing Lpass driver can not be used as-it-is for apq8016 as it contains code specific to ipq806x. Also the driver only supports single i2s port, single dma channel and single bitclk control. APQ8016 has 4 MI2S( Primary, Secondary, Tertiary, Quaternary) which can be routed to internal wcd codec or external codecs. This routing is controlled by 2 mux registers. This patch series firstly re-organizes the lpass driver such that the SOC specific bits are moved away from the driver. And secondly the SOC specifics are now passed as lpass variant data which would include various register offsets, dma channel allocations and SOC specific clock handling. Finally the patchset add apq8016 lpass and machine driver. This patchset also has two trivial cleanup patches which are to do with redundant checks and removing unnecessary header files. All these patches are tested for HDMI audio via adv7533 bridge and Analog audio on APQ8016-SBC and msm8916-mtp boards. I dont have access to ipq806x boards to test these patches. This is very first version of the patches which was developed with very mimimal/no access to IP documentation. I would like to get your opinon on the over all approch. Kenneth/Patrick, Could you please try these patches on storm board? Thanks, srini Srinivas Kandagatla (14): ASoC: qcom: Remove redundant error check.

[alsa-devel] prealloc_buffer_size and buffer_bytes_max
by Peter Rosin 21 May '15

21 May '15

Hi! I got my hopes up when I read the commit message for c14e2591bf54 ASoC: atmel-pcm-dma: increase buffer_bytes_max. Quoting it: atmel-pcm-dma is not limited to a buffer size of 64kB like atmel-pcm-pdc. Increase buffer_bytes_max to 512kB to allow for higher bit rates (i.e. 32bps at 192kHz) to work correctly. By default, keep the prealloc at 64kB. However, as I (think I) request a bigger buffer it still caps out at 64kB. I'm using the latency argument of snd_pcm_set_params to control the buffer: snd_pcm_set_params(pcm, SND_PCM_FORMAT_S32_LE, SND_PCM_ACCESS_RW_INTERLEAVED, 2, /* channels */ 250000, /* rate */ 0, /* do not resample */ 90000); /* latency in us */ But snd_pcm_hw_params_get_buffer_size "only" returns 8192 frames (64kB) even if I request 9us * 250kHz * 2 * 4 = 180kB. If I change the prealloc from 64kB to 256kB I get a bigger buffer (and it works better too!). Admittedly I backported this patch on top of the linux-3.18-at91 branch from the Atmel git repo, so there might be some support missing that has gone in after 3.18? Or have I completely misunderstood, and these are unrelated buffers? Any insight in how I can get a big enough buffer without hacking the prealloc is appreciated! Cheers, Peter

Hello, I'm having issues with the internal microphone on an Asus R553 (or S551) laptop. With the boost set to zero the microphone works but the level of the recording is very low. If I try another boost setting I don't get any signal anymore. I have uploaded alsa-info data here : http://www.alsa-project.org/db/?f=55b7fb0b4998757d099addae0a411e6a7cebc079 This is on a Linux 4.0 kernel. Any help is welcome, Regards, Simon

[alsa-devel] [REGRESSION] 4.1-rc4: Sound muted after boot
by Martin Steigerwald 21 May '15

21 May '15

Hello! On ThinkPad T520 (Intel Sandybridge) with 4.14-rc4 + two BTRFS patches and one Intel P-State debug patch I have no sound output on internal Intel HD audio codec. According to ThinkPad T520 LED with striked-through speaker the loud speaker is in disabled state. Also KDE´s Phonon says a soundcard is missing. In alsa-mixer I see nothing as MM for muted. If I press the key next to the LED I get a notification on the desktop that loud speaker has been enabled / disabled, but the LED still is on for it being disabled. I do not hear anything in Amarok or with aplay. alsa-mixer sound volumes are 100 for master and PCM. I also tried with disabling "Auto-Mute Mod", but still no sound. When I reboot and in BIOS or GRUB press the key then the LED toggles state. When I reboot into Linux 4.0.1 sound is working fine and loud speaker disabled LED is toggled off, so I bet this is a regression 4.1-rc4 compared to 4.0.1. The following is from non-working 4.1-rc4 kernel: merkaba:~> lspci -s 00:1b.0 -nnv 00:1b.0 Audio device [0403]: Intel Corporation 6 Series/C200 Series Chipset Family High Definition Audio Controller [8086:1c20] (rev 04) Subsystem: Lenovo Device [17aa:21cf] Flags: bus master, fast devsel, latency 0, IRQ 29 Memory at f2520000 (64-bit, non-prefetchable) [size=16K] Capabilities: [50] Power Management version 2 Capabilities: [60] MSI: Enable+ Count=1/1 Maskable- 64bit+ Capabilities: [70] Express Root Complex Integrated Endpoint, MSI 00 Capabilities: [100] Virtual Channel Capabilities: [130] Root Complex Link Kernel driver in use: snd_hda_intel merkaba:~> cat /proc/asound/cards 0 [PCH ]: HDA-Intel - HDA Intel PCH HDA Intel PCH at 0xf2520000 irq 29 merkaba:~> cat /proc/asound/version Advanced Linux Sound Architecture Driver Version k4.1.0-rc4-tp520-btrfstrim- pstatetrace+. merkaba:~> cat /proc/asound/devices 2: [ 0] : control 3: [ 0- 0]: digital audio playback 4: [ 0- 0]: digital audio capture 5: [ 0- 3]: digital audio playback 6: [ 0- 7]: digital audio playback 7: [ 0- 8]: digital audio playback 8: [ 0- 0]: hardware dependent 9: [ 0- 1]: hardware dependent 10: [ 0- 3]: hardware dependent 33: : timer merkaba:~> merkaba:~> aplay -L null Discard all samples (playback) or generate zero samples (capture) pulse PulseAudio Sound Server phonon HDA Intel PCH mit Mixer default:CARD=PCH HDA Intel PCH, CX20590 Analog Default Audio Device sysdefault:CARD=PCH HDA Intel PCH, CX20590 Analog Default Audio Device front:CARD=PCH,DEV=0 HDA Intel PCH, CX20590 Analog Front speakers surround21:CARD=PCH,DEV=0 HDA Intel PCH, CX20590 Analog 2.1 Surround output to Front and Subwoofer speakers surround40:CARD=PCH,DEV=0 HDA Intel PCH, CX20590 Analog 4.0 Surround output to Front and Rear speakers surround41:CARD=PCH,DEV=0 HDA Intel PCH, CX20590 Analog 4.1 Surround output to Front, Rear and Subwoofer speakers surround50:CARD=PCH,DEV=0 HDA Intel PCH, CX20590 Analog 5.0 Surround output to Front, Center and Rear speakers surround51:CARD=PCH,DEV=0 HDA Intel PCH, CX20590 Analog 5.1 Surround output to Front, Center, Rear and Subwoofer speakers surround71:CARD=PCH,DEV=0 HDA Intel PCH, CX20590 Analog 7.1 Surround output to Front, Center, Side, Rear and Woofer speakers hdmi:CARD=PCH,DEV=0 HDA Intel PCH, HDMI 0 HDMI Audio Output hdmi:CARD=PCH,DEV=1 HDA Intel PCH, HDMI 1 HDMI Audio Output hdmi:CARD=PCH,DEV=2 HDA Intel PCH, HDMI 2 HDMI Audio Output dmix:CARD=PCH,DEV=0 HDA Intel PCH, CX20590 Analog Direct sample mixing device dmix:CARD=PCH,DEV=3 HDA Intel PCH, HDMI 0 Direct sample mixing device dmix:CARD=PCH,DEV=7 HDA Intel PCH, HDMI 1 Direct sample mixing device dmix:CARD=PCH,DEV=8 HDA Intel PCH, HDMI 2 Direct sample mixing device dsnoop:CARD=PCH,DEV=0 HDA Intel PCH, CX20590 Analog Direct sample snooping device dsnoop:CARD=PCH,DEV=3 HDA Intel PCH, HDMI 0 Direct sample snooping device dsnoop:CARD=PCH,DEV=7 HDA Intel PCH, HDMI 1 Direct sample snooping device dsnoop:CARD=PCH,DEV=8 HDA Intel PCH, HDMI 2 Direct sample snooping device hw:CARD=PCH,DEV=0 HDA Intel PCH, CX20590 Analog Direct hardware device without any conversions hw:CARD=PCH,DEV=3 HDA Intel PCH, HDMI 0 Direct hardware device without any conversions hw:CARD=PCH,DEV=7 HDA Intel PCH, HDMI 1 Direct hardware device without any conversions hw:CARD=PCH,DEV=8 HDA Intel PCH, HDMI 2 Direct hardware device without any conversions plughw:CARD=PCH,DEV=0 HDA Intel PCH, CX20590 Analog Hardware device with all software conversions plughw:CARD=PCH,DEV=3 HDA Intel PCH, HDMI 0 Hardware device with all software conversions plughw:CARD=PCH,DEV=7 HDA Intel PCH, HDMI 1 Hardware device with all software conversions plughw:CARD=PCH,DEV=8 HDA Intel PCH, HDMI 2 Hardware device with all software conversions Ciao, -- Martin 'Helios' Steigerwald - http://www.Lichtvoll.de GPG: 03B0 0D6C 0040 0710 4AFA B82F 991B EAAC A599 84C7

[alsa-devel] [PATCH] SoC: sta32x: use devm_gpiod_get_optional for optional reset gpio
by Uwe Kleine-König 20 May '15

20 May '15

Since 39b2bbe3d715 (gpio: add flags argument to gpiod_get*() functions) which appeared in v3.17-rc1, the gpiod_get* functions take an additional parameter that allows to specify direction and initial value for output. Also there is a variant to find optional gpios that returns NULL if there is no gpio instead of -ENOENT. Make use of both features to simplify the driver. This changes behaviour if gpiod_get returns -ENOSYS which is the case if CONFIG_GPIOLIB is not enabled. This is a good change because without GPIOLIB there is no way to determine if the reset gpio is specified in the device tree. And if it is it must be handled, so erroring out is the right thing to do. Furthermore this is one caller less that stops us making the flags argument to gpiod_get*() mandatory.

[alsa-devel] [PATCH] ASoC: omap: fix up SND_OMAP_SOC_OMAP_ABE_TWL6040 dependency, again
by Arnd Bergmann 20 May '15

20 May '15

I tried to fix this before and submitted a working patch, but after some discussion we came up with what seemed to be a nicer solution, resulting in commit 3d4cf65e2d ("ASoC: omap: fix up SND_OMAP_SOC_OMAP_ABE_TWL6040 dependency"). Unfortunately, that version was incomplete, and we still get this build error: drivers/clk/clk-palmas.c:46:16: error: field 'hw' has incomplete type drivers/clk/clk-palmas.c: In function 'to_palmas_clks_info': drivers/clk/clk-palmas.c:54:74: warning: initialization from incompatible pointer type [-Winc This happens only in randconfig builds that turn on MFD_PALMAS on a platform other than OMAP2+ when COMPILE_TEST is set but COMMON_CLK is not. The new approach is only 'select COMMON_CLK_PALMAS' if we know that we are on an OMAP5 platform and MFD_PALMAS is already set. This patch has survived thousands of randconfig builds and I don't see a remaining hole in the logic.

[alsa-devel] [patch] ASoC: wm8741: check for error returns from wm8741_set_pdata()

Static checkers complain that "ret" is always zero so the conditions are never true. The intention here was clearly to check for errors from wm8741_set_pdata().

[alsa-devel] ALSA: dmix: pcm status incomplete
by Dan Hordern 20 May '15

20 May '15

I require timestamp information from the soundcard and host for our application. However, I noticed that when using "dmix:0,0" instead of "hw:0,0", the audio timestamp and delay frames are both zero. Looking in to the code, it seems that the 'snd_pcm_dmix_status' function does not populate either of these. In order to expose these, I have modified this function to get this information from the slave pcm; patch below. I was hoping for some feedback on this change. I am not sure if the delay value makes sense as yet, and whether there are consequences of using the hardware trigger timestamp etc. I am guessing the dsnoop and dshare plugins may also have this issue, though I have not checked.

[alsa-devel] [PATCH] ALSA: hda - Reduce verbs by node power-saves
by Takashi Iwai 20 May '15

20 May '15

The widget (node) power-saves restore the widget states at each transition from D3 to D0 on each node. This was added in the commit [d545a57c5f84:ALSA: hda - Sync node attributes at resume from widget power saving]. However, the test was rater false-positive; this wasn't needed for any codecs. Since the resync may take significant number of additional verbs to be executed, it's better to reduce it. Let's disable it for now again.

[alsa-devel] [PATCH v2] ALSA: hda - Move hda_i915.c from sound/pci/hda to sound/hda
by mengdong.lin＠intel.com 20 May '15

20 May '15

From: Mengdong Lin <mengdong.lin(a)intel.com> The file is moved to hda core and renamed to hdac_i915.c, so can be used by both legacy HDA driver and new Skylake audio driver. - Add snd_hdac_ prefix to the public APIs. - The i915 audio component is moved to core bus and dynamically allocated. - A static pointer hdac_acomp is used to help bind/unbind callbacks to get this component, because the sound card's private_data is used by the azx chip pointer, which is a legacy structure. It could be removed if private _data changes to some core structure which can be extended to find the bus. - snd_hdac_get_display_clk() is added to get the display core clock for HSW/BDW. - haswell_set_bclk() is moved to hda_intel.c because it needs to write the controller registers EM4/EM5, and only legacy HD-A needs it for HSW/BDW. - Move definition of HSW/BDW-specific registers EM4/EM5 to hda_register.h and rename them to HSW_EM4/HSW_EM5, because other HD-A controllers have different layout for the extended mode registers.

[alsa-devel] Focusrite Forte
by e-rouge 19 May '15

19 May '15

Hello, I just bought a Focusrite Forte, and yeah I've fooled by the class-compliant thingy and the touch controls. For some reasons the card controls require a deamon that only runs on window and mac. Well, OK, I'm a programmer, I can fix that. There must be a way to access all the parameters (namely gain and phantom switches). Can you provide me some basic commands to know what this card has under the hood ? What tools do you use to do that ? Thanks a lot in advance T. P.S. : well if someone has a solution out-of-the-box, I can take it too :)

[alsa-devel] [PATCH v3 00/17] new LoCoMo driver set
by Dmitry Eremin-Solenikov 19 May '15

19 May '15

Sharp Zaurus SL-5500 and SL-5600 use special companion Gate Array. With this patchset I tried to modernise and restructure the LoCoMo drivers. * Use platform bus and mfd core code * Use GPIO API instead of custom locomo GPIO code * Use irqdomains to manage IRQs * Split mixed locomolcd driver to lcd and backlight parts * Implement IRQ handling in GPIO driver * Implement SPI driver used as a host for mmc_spi device to control SD cards Changes since V2: * Implemented most of review findings (lots of small changes) * Added comments where the review feedback was ignored The following changes since commit b787f68c36d49bb1d9236f403813641efa74a031: Linux 4.1-rc1 (2015-04-26 17:59:10 -0700) are available in the git repository at: git://git.infradead.org/users/dbaryshkov/zaurus.git locomo-v3 for you to fetch changes up to c7405f110836863287c505650ac2133fecabea7b: ARM: drop old LoCoMo driver (2015-05-17 19:23:20 +0300) ---------------------------------------------------------------- Dmitry Eremin-Solenikov (17): mfd: add new driver for Sharp LoCoMo leds: port locomo leds driver to new locomo core input: convert LoCoMo keyboard driver to use new locomo core input: make LoCoMo keyboard driver support both poodle and collie video: backlight: add new locomo backlight driver video: lcd: add LoCoMo LCD driver gpio: port LoCoMo gpio support from old driver gpio: locomo: implement per-pin irq handling spi: add locomo SPI driver i2c: add locomo i2c driver ARM: sa1100: make collie use new locomo drivers ARM: sa1100: don't preallocate IRQ space for locomo ASoC: pxa: poodle: make use of new locomo GPIO interface ARM: pxa: poodle: use new LoCoMo driver ARM: pxa: poodle: don't preallocate IRQ space for locomo video: backlight: drop old locomo bl/lcd driver ARM: drop old LoCoMo driver arch/arm/common/Kconfig | 3 - arch/arm/common/Makefile | 1 - arch/arm/common/locomo.c | 914 ----------------------------- arch/arm/include/asm/hardware/locomo.h | 221 ------- arch/arm/mach-pxa/Kconfig | 1 - arch/arm/mach-pxa/include/mach/poodle.h | 8 +- arch/arm/mach-pxa/poodle.c | 58 +- arch/arm/mach-sa1100/Kconfig | 1 - arch/arm/mach-sa1100/collie.c | 213 +++++-- arch/arm/mach-sa1100/include/mach/collie.h | 16 +- arch/arm/mach-sa1100/include/mach/irqs.h | 19 +- drivers/gpio/Kconfig | 13 + drivers/gpio/Makefile | 1 + drivers/gpio/gpio-locomo.c | 285 +++++++++ drivers/i2c/busses/Kconfig | 12 + drivers/i2c/busses/Makefile | 1 + drivers/i2c/busses/i2c-locomo.c | 135 +++++ drivers/input/keyboard/Kconfig | 2 +- drivers/input/keyboard/locomokbd.c | 264 ++++----- drivers/leds/Kconfig | 2 +- drivers/leds/leds-locomo.c | 117 ++-- drivers/mfd/Kconfig | 10 + drivers/mfd/Makefile | 1 + drivers/mfd/locomo.c | 346 +++++++++++ drivers/spi/Kconfig | 10 + drivers/spi/Makefile | 1 + drivers/spi/spi-locomo.c | 332 +++++++++++ drivers/video/backlight/Kconfig | 16 +- drivers/video/backlight/Makefile | 3 +- drivers/video/backlight/locomo_bl.c | 153 +++++ drivers/video/backlight/locomo_lcd.c | 285 +++++++++ drivers/video/backlight/locomolcd.c | 255 -------- include/linux/mfd/locomo.h | 167 ++++++ sound/soc/pxa/poodle.c | 52 +- 34 files changed, 2216 insertions(+), 1702 deletions(-) delete mode 100644 arch/arm/common/locomo.c delete mode 100644 arch/arm/include/asm/hardware/locomo.h create mode 100644 drivers/gpio/gpio-locomo.c create mode 100644 drivers/i2c/busses/i2c-locomo.c create mode 100644 drivers/mfd/locomo.c create mode 100644 drivers/spi/spi-locomo.c create mode 100644 drivers/video/backlight/locomo_bl.c create mode 100644 drivers/video/backlight/locomo_lcd.c delete mode 100644 drivers/video/backlight/locomolcd.c create mode 100644 include/linux/mfd/locomo.h -- With best wishes Dmitry

[alsa-devel] [PATCH] ASoC: rt5645: fix kernel hang when call rt5645_set_jack_detect()
by John Lin 19 May '15

19 May '15

rt5645_set_jack_detect() is usually called from snd_soc_dai_link.init() and it calls snd_soc_jack_report() from rt5645_irq_detection() if jack is inserted. snd_soc_jack_report() results in kernel hang if it is called from a context which cannot sleep. This patch makes sure snd_soc_jack_report() is called from workqueue. It can fix the kernel hang issue.

[alsa-devel] [PATCH] ALSA: hda - Fix NULL dereference from CA0132 DSP loader
by Takashi Iwai 19 May '15

19 May '15

The CA0132 DSP loader leads to NULL deference since the recent transition to HDA core code, as it unconditionally accesses hdac_stream->substream->runtime. For DSP loading, the substream shouldn't be assigned. This patch addresses the NULL dereference above in addition to assure the substream is cleared while DSP loading.

[alsa-devel] [RFC PATCH] ALSA: pcm: Modify double acknowledged interrupts check condition
by Koro Chen 19 May '15

19 May '15

Currently in snd_pcm_update_hw_ptr0 during interrupt, we consider there were double acknowledged interrupts when: 1. HW reported pointer is smaller than expected, and 2. Time from last update time (hdelta) is over half a buffer time. However, when HW reported pointer is only a few bytes smaller than expected, and when hdelta is just a little larger than half a buffer time (e.g. ping-pong buffer), it wrongly treats this IRQ as double acknowledged. The condition #2 uses jiffies, but jiffies is not high resolution since it is integer. We should consider jiffies inaccuracy.
