[PATCH 0/3] SoC: SOF: ipc: Optimizations for tx message
by Peter Ujfalusi 29 Jan '22

29 Jan '22

Hi, The series will drop the internal use of 'header' parameter which is always set to hdr->cmd. The other simplification is to use the provided message directly as it is guarantied to be valid throughout the message sending and we can save memory by not allocating a temporary buffer, also saving on needles memcpy() operations.

[PATCH v2 0/3] (Re)enable DP/HDMI audio for RK3399 Gru
by Brian Norris 29 Jan '22

29 Jan '22

This series fixes DP/HDMI audio for RK3399 Gru systems. First, there was a regression with the switch to SPDIF. Patch 1 can be taken separately as a regression fix if desired. But it's not quite so useful (at least on Chrome OS systems) without the second part. Second, jack detection was never upstreamed, because the hdmi-codec dependencies were still being worked out when this platform was first supported. Patches cover a few subsystems. Perhaps this is something for arm-soc?

[PATCH] ASoC: ops: Check for negative values before reading them
by Mark Brown 29 Jan '22

29 Jan '22

The controls allow inputs to be specified as negative but our manipulating them into register fields need to be done on unsigned variables so the checks for negative numbers weren't taking effect properly. Do the checks for negative values on the variable in the ABI struct rather than on our local unsigned copy.

[PATCH] ASoC: rt5682: Fix deadlock on resume
by Peter Ujfalusi 29 Jan '22

29 Jan '22

On resume from suspend the following chain of events can happen: A rt5682_resume() -> mod_delayed_work() for jack_detect_work B DAPM sequence starts ( DAPM is locked now) A1. rt5682_jack_detect_handler() scheduled - Takes both jdet_mutex and calibrate_mutex - Calls in to rt5682_headset_detect() which tries to take DAPM lock, it starts to wait for it as B path took it already. B1. DAPM sequence reaches the "HP Amp", rt5682_hp_event() tries to take the jdet_mutex, but it is locked in A1, so it waits. Deadlock. To solve the deadlock, drop the jdet_mutex, use the jack_detect_work to do the jack removal handling, move the dapm lock up one level to protect the most of the rt5682_jack_detect_handler(), but not the jack reporting as it might trigger a DAPM sequence. The rt5682_headset_detect() can be changed to static as well.

[PATCH] ASoC: soc-pcm: Fix DPCM lockdep warning due to nested stream locks
by Takashi Iwai 29 Jan '22

29 Jan '22

The recent change for DPCM locking caused spurious lockdep warnings. Actually the warnings are false-positive, as those are triggered due to the nested stream locks for FE and BE. Since both locks belong to the same lock class, lockdep sees it as if a deadlock. For fixing this, we need take PCM stream locks for BE with the nested lock primitives. Since currently snd_pcm_stream_lock*() helper assumes only the top-level single locking, a new helper function snd_pcm_stream_lock_irqsave_nested() is defined for a single-depth nested lock, which is now used in the BE DAI trigger that is always performed inside a FE stream lock.
