alsactl: Wrong line if (!sched_setscheduler(0, SCHED_IDLE, &sched_param))

alsa-project/alsa-utils pull request #38 was opened from Oscar65: As man page says: "If successful, the sched_setparam() function shall return zero." So the if must be without ! Without update I got this output in the syslog (journalctl): abr 16 09:25:30 mypc alsactl[1652]: alsactl 1.2.2 daemon started abr 16 09:25:30 mypc alsactl[1652]: /usr/bin/alsactl: do_nice:165sched_setparam failed: No such file or directory That I think that is a wrong message. The call to sched_setparam is correct. This is the output with strace: getpriority(PRIO_PROCESS, 0) = 20 setpriority(PRIO_PROCESS, 0, 19) = 0 getpriority(PRIO_PROCESS, 0) = 1 sched_getparam(0, [0]) = 0 sched_setscheduler(0, SCHED_IDLE, [0]) = 0 write(2, "/usr/bin/alsactl: do_nice:165: ", 31/usr/bin/alsactl: do_nice:165: ) = 31 write(2, "sched_setparam failed: No such f"..., 48sched_setparam failed: No such file or directory) = 48 write(2, "\n", 1) = 1 Call to sched_setscheduler returns 0, so it means that the call was successful.

[PATCH 00/24] ASoC: SOF: topology and firmware IPC updates for 5.8
by Pierre-Louis Bossart 16 Apr '20

16 Apr '20

Long series made of a relatively small changes from multiple SOF contributors. I didn't find a good way to split this series since it tracks SOF minor ABI changes (backwards-compatible with older firmware files) and needs to be kept in-order. Future series should be much shorter. The main addition is support for an extended firmware manifest, which helps retrieve capabilities directly from the firmware file instead of the current IPC mechanism (still supported but will be deprecated). The IPC is realigned with the firmware, along with type cleanups, and the DMIC interface is simplified. The topology changes are mainly about a multi-cpu DAI fix, a new DC blocking component, better parsing of tuples and new parameters for ALH (SoundWire) and HDaudio DAIs. New tokens are also added to clarify the firmware behavior in the case of dependent pipelines, e.g. for echo reference generation.

[PATCH] ASoC: q6dsp6: q6afe-dai: add missing channels to MI2S DAIs
by Stephan Gerhold 15 Apr '20

15 Apr '20

For some reason, the MI2S DAIs do not have channels_min/max defined. This means that snd_soc_dai_stream_valid() returns false, i.e. the DAIs have neither valid playback nor capture stream. It's quite surprising that this ever worked correctly, but in 5.7-rc1 this is now failing badly: :) Commit 0e9cf4c452ad ("ASoC: pcm: check if cpu-dai supports a given stream") introduced a check for snd_soc_dai_stream_valid() before calling hw_params(), which means that the q6i2s_hw_params() function was never called, eventually resulting in: qcom-q6afe aprsvc:q6afe:4:4: no line is assigned ... even though "qcom,sd-lines" is set in the device tree. Commit 9b5db059366a ("ASoC: soc-pcm: dpcm: Only allow playback/capture if supported") now even avoids creating PCM devices if the stream is not supported, which means that it is failing even earlier with e.g.: Primary MI2S: ASoC: no backend playback stream Avoid all that trouble by adding channels_min/max for the MI2S DAIs.
