[PATCH] ASoC: codecs: lpass-rx-macro: Check for error pointer after calling devm_regmap_init_mmio
by Jiasheng Jiang 10 Jan '22

10 Jan '22

The devm_regmap_init_mmio() may return error pointer under certain circumstances, for example the possible failure of the kzalloc() in regmap_mmio_gen_context(), which is called by devm_regmap_init_mmio(). Then the rx->regmap will be error pointer and be used in rx_macro_mclk_enable(). Therefore, it should be better to check it in order to avoid the dereference of the error pointer.

amixer: needs sget/cget support in stdin mode
by GitHub issues - opened 08 Jan '22

08 Jan '22

alsa-project/alsa-utils issue #135 was opened from nick87720z: I used alsactl and amixer to implement highly effective volume control applet executor. At least it's able to keep pace at touchpad, which sends 1000 scroll events in only 18 to 12 seconds. `amixer --stdin` handles control events, while `alsactl monitor` is even source for applet display part (it's tint2 executor). But in order to get values to display - this display part has to run `alsactl sget` per request. Can't these commands be supported in stdin mode? From first look - expected lines number doesn't look unpredictable: for `sget` it depends on number of channels, and for `cget` - probably fixed. Even `controls` command also could be supported, since it lists channel from biggest ID to 1, so moment of numid=1 could be understood as end of list.

slow snd_rawmidi_drain() for VirMidi devcies
by Stefan Sauer 07 Jan '22

07 Jan '22

hi, I've tried to link BitwigStudio to the webapp cables.gl over virmidi. Unfortunately Bitwig Studio only supports rawmidi. What I discovered is that there is a strange slowness when sending data to virmidi caused by snd_rawmidi_drain(). I've posted two tiny, self-contained c apps to: https://gist.github.com/ensonic/c7588b87fa6c1fa94a8f753b1e0aa394 See some examples below. 2 observations: * snd_rawmidi_type() is *not* reporting virmidi as VIRTUAL * snd_rawmidi_drain() takes about 60ms! on virtual vs. less that 0.1 ms on usb midi (I checked all my hw midi and the worst was avg=1ms on physical midi image unitor8) When comparing the implementations: https://github.com/alsa-project/alsa-lib/blob/master/src/rawmidi/rawmidi_vi… https://github.com/alsa-project/alsa-lib/blob/master/src/rawmidi/rawmidi_hw… I see that the hw one results in an IOCTL which I can see when striking the code and I wonder if this is the root cause? Why is rawmidi_virt.c not used for virmidi? >From poking at snd_rawmidi_open_conf() I have not yet figured where this is decided ....

[PATCH 0/2] Add low power hibernation support to cs35l41
by Charles Keepax 07 Jan '22

07 Jan '22

This patch series adds support for the low power hibernation feature on cs35l41. This allows the DSP memory to be retained whilst the device enters a very low power state. These patches will cause some very minor conflicts with Lucas's currently outstanding work on the HDA version of cs35l41. Whilst things will still build (well now I fixed my silly mistake), this patch adds a test key function his code will now have to call. It looks like Lucas's patch might get a respin based on the comments from Andy, in which case I guess we can pull the small change into the next version of it. But either way these patches are not urgent so I am happy if they sit around until Lucas's stuff is merged too.

[PATCH 0/5] ASoC: Xilinx fixes
by Robert Hancock 07 Jan '22

07 Jan '22

There are drivers in mainline for the Xilinx Audio Formatter and Xilinx I2S IP cores. However, because of a few issues, these were only really usable with Xilinx's xlnx_pl_snd_card top-level driver, which is not in mainline (and not suitable for mainline). The fixes in this patchset, for the simple-card layer as well as the Xilinx drivers, now allow these drivers to be properly used with simple-card without any out-of-tree support code.

[PATCH] ALSA: hda: Fix dependency on ASoC cs35l41 codec
by Takashi Iwai 07 Jan '22

07 Jan '22

The recently added support for CS35L41 codec unconditionally selects CONFIG_SND_SOC_CS35L41_LIB, but this can't work unless the top-level CONFIG_SND_SOC is enabled.
