[alsa-devel] [PATCH v6 0/6] Implement generic ASoC HDMI codec and use it in tda998x
by Jyri Sarha 10 Mar '16

10 Mar '16

There is currently two other patch series[1][2] that depend on the three first (ALSA-) patches of this series. It would be nice to get at least those three applied sooner rather than later, so please tell me if I can do anything to get those in. BTW, I applied the relevant patches from the two series to on top of this one. Obviously the two series conflicted with each other a bit and also the IEC958 helper patch from [2] conflicted with the IEC958 patch from my series (which is weird since Arnaud's series depends on my series...). After resolving the conflicts everything compiled fine, but for some reason neither the 'ELD' or IEC958 Playback Default' appeared on my BBB. I'll try to find time to debug this further at some point. [1] http://mailman.alsa-project.org/pipermail/alsa-devel/2016-March/105509.html [2] http://mailman.alsa-project.org/pipermail/alsa-devel/2016-March/105502.html Changes since v5 - Rebased on top of the latest drm-next branch - Allow 32 bit samplewidth in snd_pcm_create_iec958_consumer() and snd_pcm_create_iec958_consumer_hw_params() - Propose new simpler DT binding for tda998x audio - Squash tda998x audio DT binding together with hdmi-codec integration Changes since RFC v4, - Rebased on top of the latest drm-next branch - Split the hdmi-codec abort functionality into a separate patch for better visibility of what it is all about - This does not affect the tda998x patches as the abort functionality is not used - Drop S18_3* formats from I2S_FORMATS and add a comment about formats not supported by HDMI Changes since RFC v3, ASoC side: - Add "ALSA: pcm: add IEC958 channel status helper for hw_params" - Add "tda998x: Improve tda998x_configure_audio() audio related pdata" - use snd_pcm_create_iec958_consumer_hw_params() to construct the stream header - Remove set_clk() callback from hdmi-codec. It is not needed for now. - Refer to stream header in AIF as specified in HDMI standard - Set current_stream to NULL only after video side audio_shutdown() has been called. Avoid potential race if video side attempts to abort audio at the same time. - No need to have video side device pointer in the hdmi codec's pdata as it is found from dev->parent. - Fix hdmi-codec enum: DAI_ID_I2C > DAI_ID_I2S - Improve audio_startup API comment - Make improved checkpatch happy - BUG_ON > WARN_ON - put */ ending the block comment to a separate line DRM side: - Fix tda998x get_eld() locking - Change tda998x audio parameters in pdata to more generic, that can be readily used in tda998x_audio_config() - Rename and restructure audio port related private data members to be more descriptive - Require audio configuration trough ASoC hdmi-codec if HDMI audio is configured trough DT binding.

[alsa-devel] [PATCH 0/4] ALSA: dice: enable to handle several streams
by Takashi Sakamoto 10 Mar '16

10 Mar '16

Hi, This patchset updates my previous RFT, and goes for merging. [alsa-devel] [RFT][PATCH 0/4] ALSA: dice: enabled to handle several streams http://mailman.alsa-project.org/pipermail/alsa-devel/2016-March/105387.html For the previous one, Stefan Richter worked as a tester with his devices (Focusrite Saffire Pro 24 and 40), while current patchset includes changes related to userspace interface. Therefore, I don't add Tested-by. In previous one, ALSA dice driver uses subdevice for userspace to access any PCM substreams. On the other hand, the design of PCM subdevice leaves a bit cumbersome for userspace to handle several subdevices simultaneously in one process. These PCM substreams on a batch of AMDTP streams and it's better for ALSA dice driver to enable one process to handle them with simpler way. Based on this concept, this patchset adds PCM character devices, instead of PCM subdevice. Thus, userspace applications can utilize PCM substreams via individual PCM character devices. In configuration space of alsa-lib, via 'hw:0,0' and 'hw:0,1' if available, like: $ arecord -l ... card 1: Pro26000f5a [Pro26-000f5a], device 0: DICE [Pro26-000f5a] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: Pro26000f5a [Pro26-000f5a], device 1: DICE [Pro26-000f5a] Subdevices: 1/1 Subdevice #0: subdevice #0 For the other parts, there's no code changes. Therefore, Stefan's result still has meanings. Changes: * Add additional PCM character device instead of PCM subdevice * Correct string entries to force-pcm * Improve comments Takashi Sakamoto (4): ALSA: dice: have two sets of isochronous resources/streams ALSA: dice: handle whole available isochronous streams ALSA: dice: handle several PCM substreams when any isochronous streams are available ALSA: dice: force to add two pcm devices for listed models sound/firewire/dice/dice-midi.c | 8 +- sound/firewire/dice/dice-pcm.c | 147 +++++++++----- sound/firewire/dice/dice-stream.c | 398 ++++++++++++++++++++++++-------------- sound/firewire/dice/dice.c | 41 ++++ sound/firewire/dice/dice.h | 33 +++- 5 files changed, 424 insertions(+), 203 deletions(-) -- 2.7.0

[alsa-devel] Scheduled alsa-lib release?
by Takashi Iwai 09 Mar '16

09 Mar '16

Hi, in the previous meeting, there have been requests about the regular "predictable" release of alsa-lib. We thought of aligning with kernel release cycle, judging from the nature of alsa-lib. alsa-lib 1.1.0 was released in the beginning of November, which was just after 4.3 kernel release. Now 4.5 kernel release will be likely in the next week or one week after that. Jaroslav, how about releasing alsa-lib 1.1.1 around that? There are a few pending patches, but they should be available soon. thanks, Takashi

[alsa-devel] [PATCH] Show sequencer sound card numer/PID via aconnect
by Martin Koegler 09 Mar '16

09 Mar '16

From: Martin Koegler <martin.koegler(a)chello.at> rawmidi devices expose the card number via IOCTLs, which allows to find the corresponding device in sysfs. The sequencer provides no identifing data. Chromium works around this issue by scanning rawmidi as well as sequencer devices and matching them by using assumtions, how the kernel register sequencer devices. This patch adds support for displaying the sound card number/PID to aconnect.

[alsa-devel] alsa-plugins: pcm_a52.c uses recently removed avcodec_{alloc, free}_frame

pcm_a52.c uses avcodec_alloc_frame and avcodec_free_frame that have been replaced by av_frame_alloc and av_frame_free in recent versions of libavcodec.

[alsa-devel] [PATCH v4] ASoC: imx-wm8958: add imx-wm8958 machine driver

This is an initial imx-wm8958 device-tree-only machine driver. The sound card driver support three dai link, HIFI, VOICE and BT. We can configure the cpu dai from device tree, if present it will create corresponding sound card subdevice. So at least one cpu dai phandle should be set from device tree.
