[RESEND PATCH 0/6] ASoC: mediatek: mt8192: support new machine rt1015p_rt5682
by Tzung-Bi Shih 02 Dec '20

02 Dec '20

The series supports new machines with rt1015p and rt5682. Reuses most of the code in mt8192-mt6359-rt1015-rt5682.c. The first 3 patches refactor the existing mt8192-mt6359-rt1015-rt5682.c. For easier to support newly added components later. The 4th patch fixes a typo in DT bindings document. The 5th patch proposes a new compatible string "mt8192_mt6359_rt1015p_rt5682" for machines with rt1015p and rt5682. The 6th patch reuses the existing machine driver to support machines with rt1015p and rt5682.

How to interperet snd_pcm_htimestamp available frames?
by Eric Buddington 02 Dec '20

02 Dec '20

I am recording from multiple (cheap USB) mics, and trying to synchronize them. I am assuming that there will be a common minimum latency (reflecting an uncontested USB bus), with occasional spikes up - but not down. In my loop, I am calling snd_pcm_mmap_begin(), snd_pcm_htimestamp(), and snd__mmap_commit() in that order. My question is about the 'avail' value returned from htimestamp. It is documented as "Number of available frames when timestamp was grabbed". Does this mean frames since the last frame consumed with _mmap_commit()? Is there a possibility of there being no timestamp, or one where 'avail' refers to some older state? Thanks for any insight. -Eric

[PATCH v1] ASoC: Intel: catpt: Replace open coded variant of resource_intersection()

[PATCH] soundwire: master: use pm_runtime_set_active() on add
by Bard Liao 02 Dec '20

02 Dec '20

From: Pierre-Louis Bossart <pierre-louis.bossart(a)linux.intel.com> The 'master' device acts as a glue layer used during bus initialization only, and it needs to be 'transparent' for pm_runtime management. Its behavior should be that it becomes active when one of its children becomes active, and suspends when all of its children are suspended. In our tests on Intel platforms, we routinely see these sort of warnings on the initial boot: [ 21.447345] rt715 sdw:3:25d:715:0: runtime PM trying to activate child device sdw:3:25d:715:0 but parent (sdw-master-3) is not active This is root-caused to a missing setup to make the device 'active' on probe. Since we don't want the device to remain active forever after the probe, the autosuspend configuration is also enabled at the end of the probe - the device will actually autosuspend only in the case where there are no devices physically attached. In practice, the master device will suspend when all its children are no longer active.

Asoc: Intel: SST (CHT) regression in asoc/for-5.11
by Hans de Goede 02 Dec '20

02 Dec '20

Hi All, To test the code to dynamically switch between SST/SOF support on BYT/CHT from the kernel commandline I merged: https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git/log/?h=fo… Into my personal tree (mostly Linus' master + some pending patches from myself). After this I was getting the following errors in dmesg when using sound on a Medion E2228T laptop with a CHT SoC + NAU8824 codec: [ 53.805205] intel_sst_acpi 808622A8:00: Wait timed-out condition:0x0, msg_id:0x1 fw_state 0 [ 53.805479] intel_sst_acpi 808622A8:00: fw returned err -16 [ 53.806281] sst-mfld-platform sst-mfld-platform: ASoC: PRE_PMD: pcm0_in event failed: -16 [ 54.829548] intel_sst_acpi 808622A8:00: Wait timed-out condition:0x0, msg_id:0x1 fw_state 0 [ 54.829596] intel_sst_acpi 808622A8:00: fw returned err -16 [ 54.829668] sst-mfld-platform sst-mfld-platform: ASoC: POST_PMD: media0_out event failed: - [ 55.853230] intel_sst_acpi 808622A8:00: Wait timed-out condition:0x0, msg_id:0x1 fw_state 0 [ 55.853244] intel_sst_acpi 808622A8:00: fw returned err -16 [ 55.853269] sst-mfld-platform sst-mfld-platform: ASoC: POST_PMD: codec_out0 mix 0 event fai [ 56.876435] intel_sst_acpi 808622A8:00: Wait timed-out condition:0x0, msg_id:0x1 fw_state 0 [ 56.876481] intel_sst_acpi 808622A8:00: fw returned err -16 [ 56.876563] sst-mfld-platform sst-mfld-platform: ASoC: POST_PMD: media0_out mix 0 event fai [ 61.847455] intel_sst_acpi 808622A8:00: FW sent error response 0x40015 [ 61.847564] intel_sst_acpi 808622A8:00: fw returned err -1 [ 61.847659] sst-mfld-platform sst-mfld-platform: ASoC: error at snd_soc_dai_startup on ssp2 [ 61.847722] SSP2-Codec: ASoC: BE open failed -1 [ 61.847754] Audio Port: ASoC: failed to start some BEs -1 [ 61.847786] intel_sst_acpi 808622A8:00: FW sent error response 0x40006 [ 64.301284] intel_sst_acpi 808622A8:00: FW sent error response 0x90001 [ 64.301545] intel_sst_acpi 808622A8:00: not suspending FW!!, Err: -2 Dropping the asoc/for-5.11 merge and just cherry-picking Pierre-Louis' changes for the dynamic switching makes these go away. So this seems to be caused by other changes in asoc/for-5.11. So any clues where to start looking for this, or should I just bisect this? Regards, Hans
