[alsa-devel] [PATCH 0/9] add ASoC components for AHUB
by Sameer Pujar 19 Feb '20

19 Feb '20

Overview ======== The Audio Hub (AHUB) is part of the Audio Processing Engine (APE) which comprises a collection of hardware accelerators for audio pre-processing and post-processing. It also includes a programmable full crossbar for routing audio data across these accelerators. This series exposes some of these below mentioned HW devices as ASoC components for Tegra platforms from Tegra210 onwards. * ADMAIF : The interface between ADMA and AHUB * XBAR : Crossbar for routing audio samples across various modules * I2S : Inter-IC Sound Controller * DMIC : Digital Microphone * DSPK : Digital Speaker Following is the summary of current series. 1. Add YAML DT binding documentation for above mentioned modules. 2. ACIF programming is same for Tegra generations and hence it is moved to a common file. 3. Add ASoC driver components for each of the above modules. 4. Add DT entries for above components for Tegra210, Tegra186 and Tegra194. 5. Enable these components for Jetson-Tx1, Jetson-Tx2 and Jetson-Xavier. Machine driver series will be sent separately.

[alsa-devel] [PATCH v4 00/11] ASoC: SOF: Data probing
by Cezary Rojewski 18 Feb '20

18 Feb '20

This set of patches achieves few goals in order to enable data probing feature for audio DSP. First, provide new and alter existing interfaces (page allocation, runtime flow adjustments) to make them compress friendly. For HDA part, work has been done to account for compress streams when servicing IRQs, setting up BDLs and assigning DMAs. Finally, the end goal which are the probe APIs and usage itself. Probes can be treated as endpoints which allow for data extraction from or injection to target module - a great ally when debugging problematic audio issues such as distortions, glitches or gaps. Compress streams are a weapon of choice here to provide a lightweight implementation. While all available IPCs have been defined, current implementation covers extraction only, with injection scheduled for a later date. Initial review and development of probes can be found under: https://github.com/thesofproject/linux/pull/1276 with the hda-compress-enable set of patches being separated and reviewed on: https://github.com/thesofproject/linux/pull/1571 Tested on CML-U with rt5682 i2s board. Changes in v4: - No changes to ALSA core and hda patches - 'probe' source added in patch "ASoC: SOF: Implement Probe IPC API" now only compiled if SND_SOC_SOF_DEBUG_PROBES is enabled. Said kconfig initial declaration has been moved to that patch too - 'extractor_stream_tag' field now decorated with _DEBUG_PROBES to account for the change above - Debugfs probe handlers now check if extractor stream is running before continuing. To achieve this, 'extractor_stream_tag' is both initialized and set to SOF_PROBE_INVALID_NODE_ID on sof_probe_compr_free(). Suggestion provided by Pierre - Reverted SND_SOC_SOF_HDA_LINK requirement-removal change for HDA probes. Code requires SND_HDA_EXT_CORE in order to function on Intel platforms - Relocated probe-compress related code from /sof/pcm.c directly to /sof/compress.c as requested by Daniel Changes in v3: - No changes to ALSA core and hda patches - Addressed sparse and all doc related warnings as reported by Pierre - Moved _DEBUG_PROBES config outside of _DEVELOPER_SUPPORT block - Renamed 'extractor' field to 'extractor_stream_tag' as requested - Relocated 'extractor_stream_tag' declaration from patch 07 to 08 Changes in v2: - No changes to ALSA core and hda patches - Removed "ASoC: Intel: sof_rt5682: Add compress probe DAI links" from the patchset list as requested by Pierre - updated copyright header for newly added files (dates) - probes over HDA no longer require SND_SOC_SOF_HDA_LINK enabled - renamed debugfs probe functions as requested by Pierre - probe IPC API has been updated to align with newest SOF FW & probe debug app (struct_size macro has been enlisted to make the size calculations transparent).

[alsa-devel] [RFC] ASoC: soc-pcm: crash in snd_soc_dapm_new_dai
by Sameer Pujar 17 Feb '20

17 Feb '20

Crash happens in snd_soc_dapm_new_dai() when substream->private_data access is made and substream is NULL here. This is seen for DAIs where only playback or capture stream is defined. This seems to be happening for codec2codec DAI link. Both playback and capture are 0 during soc_new_pcm(). This is probably happening because cpu_dai and codec_dai are both validated either for SNDRV_PCM_STREAM_PLAYBACK or SNDRV_PCM_STREAM_CAPTURE. Shouldn't be playback = 1 when, - playback stream is available for codec_dai AND - capture stream is available for cpu_dai and vice-versa for capture = 1?

[alsa-devel] [PATCH] ALSA: pcm: Fix memory leak at closing a stream without hw_free
by Takashi Iwai 13 Feb '20

13 Feb '20

ALSA PCM core recently introduced a new managed PCM buffer allocation mode that does allocate / free automatically at hw_params and hw_free. However, it overlooked the code path directly calling hw_free PCM ops at releasing the PCM substream, and it may result in a memory leak as spotted by syzkaller when no buffer preallocation is used (e.g. vmalloc buffer). This patch papers over it with a slight refactoring. The hw_free ops call and relevant tasks are unified in a new helper function, and call it from both places.

[alsa-devel] [PATCH v2 0/5] soundwire: intel: add DAI callbacks
by Pierre-Louis Bossart 13 Feb '20

13 Feb '20

The existing mainline code is missing most of the DAI callbacks needed for a functional implementation, and the existing ones need to be modified to provide the relevant information to SOF drivers. As suggested by Vinod, these patches are shared first - with the risk that they are separated from the actual DAI enablement, so reviewers might wonder why they are needed in the first place. For reference, the complete set of 90+ patches required for SoundWire on Intel platforms is available here: https://github.com/thesofproject/linux/pull/1692 changes since v1: Fix string allocation (only feedback from Vinod) Pierre-Louis Bossart (2): soundwire: intel: rename res field as link_res soundwire: intel: free all resources on hw_free() Rander Wang (3): soundwire: intel: add prepare support in sdw dai driver soundwire: intel: add trigger support in sdw dai driver soundwire: intel: add sdw_stream_setup helper for .startup callback drivers/soundwire/intel.c | 197 ++++++++++++++++++++++++++++++++++---- 1 file changed, 177 insertions(+), 20 deletions(-) -- 2.20.1

[alsa-devel] [PATCH v2 0/5] soundwire: stream: fix state machines and transitions
by Pierre-Louis Bossart 13 Feb '20

13 Feb '20

The existing stream support works fine with simple cases, but does not map well with ALSA transitions for underflows/resume where prepare() can be called multiple times. Concurrency with multiple devices per links or multiple streams enabled on the same link also needs to be fixed. These patches are the result of hours of validation on the Intel side and should benefit other implementations since there is nothing hardware-specific. The Intel-specific changes being reviewed do depend on those stream changes though to be functional. Changes since v1: Removed spurious code block change flagged by Vinod No change (replies provided in v1 thread) Github link issue is public, no reason to remove it Bandwidth computation on ALSA prepare/start (for resume cases) handled internally in stream layer. Kept emacs comment formatting. No additional code/test for concurrent streams (not supported due to locking) Bard Liao (1): soundwire: stream: only prepare stream when it is configured. Pierre-Louis Bossart (2): soundwire: stream: update state machine and add state checks soundwire: stream: do not update parameters during DISABLED-PREPARED transition Rander Wang (2): soundwire: stream: fix support for multiple Slaves on the same link soundwire: stream: don't program ports when a stream that has not been prepared Documentation/driver-api/soundwire/stream.rst | 61 +++++++++---- drivers/soundwire/stream.c | 90 ++++++++++++++++--- 2 files changed, 124 insertions(+), 27 deletions(-) -- 2.20.1

Hi Sirs, Here is chromebook SW team from Compal. As the mail title, we hit issue that the external monitor will flash once when play video after hot pluging. We can reproduce not only on chromebook but also ubuntu 16.04. There has higher failure rate with Dell Solomon dock and Dell S2718D monitor. We found adding the delay in "sound/pci/hda/patch_hdmi.c " can fix this issue.(as the attachment) May need your help to review and advice. Thanks. Here is the issue number in gitlab for more detail. https://gitlab.freedesktop.org/drm/intel/issues/318 AJ Cheng NID/NID1 e-mail: AJ_Cheng(a)compal.com<mailto:AJ_Cheng@compal.com> Tel: +886-2-8797-8599 ext. 17561 Mobile : +886-932827829 COMPAL Electronics, Inc.
