[alsa-devel] [PATCH 11/17] ASoC: cros_ec_codec: Use cros_ec_send_cmd_msg()
by Prashant Malani 03 Feb '20

03 Feb '20

Replace send_ec_host_command() with cros_ec_send_cmd_msg() which does the same thing, but is defined in a common location in platform/chrome and exposed for other modules to use. This allows us to remove send_ec_host_command() entirely.

[alsa-devel] [PATCH v5 00/17] soundwire: intel: implement new ASoC interfaces
by Pierre-Louis Bossart 03 Feb '20

03 Feb '20

This patchset applies on top of soundwire/next, now that the interface definitions are merged. The changes are essentially a removal of the platform devices, replaced by explicit device(s)/driver for the SoundWire Master(s), and the implementation of the new interfaces required to scan the ACPI tables, probe the links and start them. The missing prepare, trigger and setup ASoC callbacks are also implemented. The hw_params and free callbacks use the new interfaces as well. While there are quite a few lines of code changed, this is mostly about interface changes. The next series will contain more functional changes and deal with race conditions on probe, enumeration and suspend/resume issues. Thanks to Vinod Kould and GregKH for the reviews on previous versions, much appreciated. Changes since v4: (feedback from GregKH except last point flagged by Intel validation) Clarified error handling with uevents Added better commit messages and rationale behind exposing a Master Device. Used 'master_device' instead of 'md' when possible (kept the shortcut with really long function names) Added namespace check support for Intel code (the Cadence and core stuff should be done in a separate patchset). Fixed GPLv2 license/EXPORT_SYMBOL_GPL error for the Master Device code. Fixed missing error handling in sdw_md_add Added kerneldoc comments for sdw_md_driver structure (with explanation on what 'md' stands for) Fixed NULL pointer assignment leading to issues with driver_unregister Changes since v3: One line change to re-add EXPORT_SYMBOL Add missing driver_registration Changes since v2: moved uevent handling to slave_type (Vinod) Changes since v1: fix typo (Vinod) removed uevent open for Master (Vinod) clarified commit messages (Cezary) no functionality change Bard Liao (1): soundwire: register master device driver Pierre-Louis Bossart (13): soundwire: renames to prepare support for master drivers/devices soundwire: rename dev_to_sdw_dev macro soundwire: rename drv_to_sdw_slave_driver macro soundwire: bus_type: rename sdw_drv_ to sdw_slave_drv soundwire: intel: rename res field as link_res soundwire: add support for sdw_slave_type soundwire: slave: move uevent handling to slave device level soundwire: add initial definitions for sdw_master_device soundwire: intel: remove platform devices and use 'Master Devices' instead soundwire: intel: free all resources on hw_free() soundwire: intel_init: add implementation of sdw_intel_enable_irq() soundwire: intel_init: use EXPORT_SYMBOL_NS soundwire: intel: use EXPORT_SYMBOL_NS 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/base/regmap/regmap-sdw.c | 4 +- drivers/soundwire/Makefile | 2 +- drivers/soundwire/bus.c | 2 +- drivers/soundwire/bus.h | 2 + drivers/soundwire/bus_type.c | 70 ++++--- drivers/soundwire/intel.c | 281 +++++++++++++++++++++----- drivers/soundwire/intel.h | 8 +- drivers/soundwire/intel_init.c | 312 ++++++++++++++++++++++------- drivers/soundwire/master.c | 64 ++++++ drivers/soundwire/slave.c | 10 +- include/linux/soundwire/sdw.h | 42 +++- include/linux/soundwire/sdw_type.h | 34 +++- 12 files changed, 668 insertions(+), 163 deletions(-) create mode 100644 drivers/soundwire/master.c -- 2.20.1

[alsa-devel] [PATCH v3 0/4] ALSA: hda - Add DP-MST support for NVIDIA codecs
by Nikhil Mahale 03 Feb '20

03 Feb '20

Today, DisplayPort multi-stream transport (DP-MST) audio is not supported on codec drivers which don't use the audio component (acomp) binding. The commit ade49db337a9 (ALSA: hda/hdmi - Allow audio component for AMD/ATI and Nvidia HDMI) added the DRM audio component binding for the NVIDIA codec drivers, but the traditional HD-audio unsolicited event code path is still in use by the proprietary NVIDIA graphics driver. This patch set adds DP-MST audio support for non-acomp codec drivers which use the traditional HD-audio unsolicited event code path. This patch set adds DP-MST support for NVIDIA codecs. The patch set has been tested for HDMI/DP-SST/DP-MST(4 dp-mst audio streams) configurations on NVIDIA Kepler and Maxwell GPUs, using both the nouveau driver and the proprietary NVIDIA graphics driver. Nikhil Mahale (4): ALSA: hda - Rename snd_hda_pin_sense to snd_hda_jack_pin_sense ALSA: hda - Add DP-MST jack support ALSA: hda - Add DP-MST support for non-acomp codecs ALSA: hda - Add DP-MST support for NVIDIA codecs sound/pci/hda/hda_jack.c | 151 ++++++++++++++++++-------- sound/pci/hda/hda_jack.h | 107 ++++++++++++++++-- sound/pci/hda/patch_hdmi.c | 263 +++++++++++++++++++++++++++++++-------------- 3 files changed, 385 insertions(+), 136 deletions(-) -- 2.16.4

[alsa-devel] [PATCH] Revert "ASoC: tegra: Allow 24bit and 32bit samples"
by Jon Hunter 02 Feb '20

02 Feb '20

Commit f3ee99087c8ca0ecfdd549ef5a94f557c42d5428 ("ASoC: tegra: Allow 24bit and 32bit samples") added 24-bit and 32-bit support for to the Tegra30 I2S driver. However, there are two additional commits that are also needed to get 24-bit and 32-bit support to work correctly. These commits are not yet applied because there are still some review comments that need to be addressed. With only this change applied, 24-bit and 32-bit support is advertised by the I2S driver, but it does not work and the audio is distorted. Therefore, revert this patch for now until the other changes are also ready. Furthermore, a clock issue with 24-bit support has been identified with this change and so if we revert this now, we can also fix that in the updated version.

[alsa-devel] [PATCH] ALSA: pcm: Fix sparse warnings wrt snd_pcm_state_t
by Takashi Iwai 31 Jan '20

31 Jan '20

Since we have a bitwise definition of snd_pcm_state_t and use it for certain struct fields, a few new (and years old) sparse warnings came up. This patch is an attempt to cover them. - The state fields in snd_pcm_mmap_status* and co are all defined as snd_pcm_state_t type now - The PCM action callbacks take snd_pcm_state_t argument as well; some actions taking special values got the explicit cast and comments - For the PCM action that doesn't need an extra argument receives ACTION_ARG_IGNORE instead of ambiguous 0 While we're at it, the boolean argument is also properly changed to bool and true/false, as well as a slight refactoring of PCM pause helper function to make easier to read. No functional changes, just shutting up chatty sparse.

[alsa-devel] [PATCH v3 00/11] ASoC: SOF: Data probing
by Cezary Rojewski 31 Jan '20

31 Jan '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 v3: - 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] [PATCH] ASoC: rt5659: add S32_LE format
by Sameer Pujar 31 Jan '20

31 Jan '20

ALC5659 supports maximum data length of 24-bit. Currently driver supports S24_LE which is a 32-bit container with valid data in [23:0] and 0s in MSB. S24_3LE is not commonly used and is hard to find audio streams with this format. Also many SoC HW do not support S24_LE and S32_LE is used in general. The 24-bit data can be represented in S32_LE [31:8] and 0s are padded in LSB. This patch adds S32_LE to ALC5659 driver and data length for this is set to 24 as per codec's maximum data length support. This helps to play 24-bit audio, packed in S32_LE, on HW which do not support S24_LE.
