[PATCH 1/3] ASoC: codecs: hdac_hdmi: Fix incorrect use of list_for_each_entry
by Amadeusz Sławiński 16 Apr '20

16 Apr '20

If we don't find any pcm, pcm will point at address at an offset from the the list head and not a meaningful structure. Fix this by returning correct pcm if found and NULL if not.

Volume is not restored after boot

alsa-project/alsa-utils issue #39 was opened from Oscar65: I have archlinux updated system last sunday. ``` $ uname -a Linux mypc 5.6.3-arch1-1 #1 SMP PREEMPT Wed, 08 Apr 2020 07:47:16 +0000 x86_64 GNU/Linux ``` I checked with alsa-restore.service and alsa-state.service. None of them work as expected. My sound card is: ``` # lshw -C sound *-multimedia description: Audio device product: 82801H (ICH8 Family) HD Audio Controller vendor: Intel Corporation physical id: 1b bus info: pci@0000:00:1b.0 version: 02 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list configuration: driver=snd_hda_intel latency=0 resources: irq:29 memory:ffaf8000-ffafbfff ``` Every time that my system boots the volume levels are different than last time a powered off.

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 v2 0/5] Add support for SOF on i.MX8M
by Daniel Baluta 16 Apr '20

16 Apr '20

From: Daniel Baluta <daniel.baluta(a)nxp.com> This patch series adds support for SOF on i.MX8M family. First board from this family that has a DSP is i.MX8MP. First 2 patches are trying to fix some compilation issues, the next two are adding the imx8m support and the last one adds the devicetree binding. Changes since v2: - add reviewed by from Rob to DT patch - fix ownership for patch 2 Daniel Baluta (3): ASoC: SOF: imx: Add i.MX8M HW support ASoC: SOF: Add i.MX8MP device descriptor dt-bindings: dsp: fsl: Add fsl,imx8mp-dsp entry Pierre-Louis Bossart (1): ASoC: SOF: imx: fix undefined reference issue YueHaibing (1): ASoC: SOF: imx8: Fix randbuild error .../devicetree/bindings/dsp/fsl,dsp.yaml | 2 + sound/soc/sof/imx/Kconfig | 32 +- sound/soc/sof/imx/Makefile | 2 + sound/soc/sof/imx/imx8m.c | 279 ++++++++++++++++++ sound/soc/sof/sof-of-dev.c | 14 + 5 files changed, 325 insertions(+), 4 deletions(-) create mode 100644 sound/soc/sof/imx/imx8m.c -- 2.17.1

[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.
