Issue in pcm_dsnoop.c in alsa-lib
by GitHub issues - edited 02 Mar '22

02 Mar '22

alsa-project/alsa-lib issue #213 was edited from TE-N-ShengjiuWang: Hi Takashi Iwai, Jaroslav Kysela We encountered an issue in the pcm_dsnoop use case, could you please help to have a look? Issue description: With two instances for dsnoop type device running in parallel, after suspend/resume, one of the instances will be hung in memcpy because the very large copy size is obtained. ``` #3 0x0000ffffa78d5098 in snd_pcm_dsnoop_sync_ptr (pcm=0xaaab06563da0) at pcm_dsnoop.c:158 dsnoop = 0xaaab06563c20 slave_hw_ptr = 64 old_slave_hw_ptr = 533120 avail = 187651522444320 ``` Reason analysis: The root cause that I analysis is that after suspend/resume, one instance will get the SND_PCM_STATE_SUSPENDED state from slave pcm device, then it will do snd_pcm_prepare() and snd_pcm_start(), which will reset the dsnoop->slave_hw_ptr and the hw_ptr of slave pcm device, then the state of this instance is correct. But another instance may not get the SND_PCM_STATE_SUSPENDED state from slave pcm device because slave device may have been recovered by first instance, so the dsnoop->slave_hw_ptr is not reset. but because hw_ptr of slave pcm device has been reset, so there will be a very large "avail" size. Solution: I didn't come up with a fix for this issue, seems there is no easy way to let another instance know this case and reset the dsnoop->slave_hw_ptr, could you please help?

[PATCH 0/2] ASoC: codecs: Add Awinic AW8738 audio amplifier driver
by Stephan Gerhold 02 Mar '22

02 Mar '22

This series adds a simple driver and DT schema for the Awinic AW8738 audio amplifier. It's fairly simple - the main difference to simple-amplifier is that there is a "one-wire pulse control" that allows configuring the amplifier to one of a few pre-defined modes.

[PATCH 0/8] ASoC: Intel: machine driver updates for 5.18
by Pierre-Louis Bossart 02 Mar '22

02 Mar '22

Two cleanups to remove an unused filename and typos, and one addition of an ACPI matching table for a Dell SoundWire SKU without local microphones. The main change is the addition of a common 'sof-ssp-amp' machine driver for devices with amplifiers only (no headset codec) and different connections using I2S links (Bluetooth offload, HDMI receiver). It's likely that the amplifier will be swapped out by OEMs, this machine driver provides a relatively generic solution to avoid copy-paste of similar solutions.

[PATCH v2] ASoC: soc-compress: prevent the potentially use of null pointer
by Jiasheng Jiang 02 Mar '22

02 Mar '22

There is one call trace that snd_soc_register_card() ->snd_soc_bind_card()->soc_init_pcm_runtime() ->snd_soc_dai_compress_new()->snd_soc_new_compress(). In the trace the 'codec_dai' transfers from card->dai_link, and we can see from the snd_soc_add_pcm_runtime() in snd_soc_bind_card() that, if value of card->dai_link->num_codecs is 0, then 'codec_dai' could be null pointer caused by index out of bound in 'asoc_rtd_to_codec(rtd, 0)'. And snd_soc_register_card() is called by various platforms. Therefore, it is better to add the check in the case of misusing. And because 'cpu_dai' has already checked in soc_init_pcm_runtime(), there is no need to check again. Adding the check as follow, then if 'codec_dai' is null, snd_soc_new_compress() will not pass through the check 'if (playback + capture != 1)', avoiding the leftover use of 'codec_dai'.
