[PATCH v1] ALSA: hda/tas2781: Support ACPI_ID both TXNW2781 and TIAS2781
by Shenghao Ding 12 Sep '23

12 Sep '23

Support ACPI_ID both TXNW2781 and TIAS2781, TXNW2781 is the only one legal ACPI ID, TIAS2781 is the widely-used ACPI ID named by our customers, so far it is not registered. We have discussed this with them, they requested TIAS2781 must be supported for the laptops already released to market, their new laptops will switch to TXNW2781. Signed-off-by: Shenghao Ding <shenghao-ding(a)ti.com> --- Changes in v1: - Add TXNW2781 into tas2781_acpi_hda_match and move it to the top - Redefine tas2781_generic_fixup, remove hid param - TIAS2781 has been used by our customers, see following dstd.dsl.

[PATCH] ASoC: amd: yc: Fix non-functional mic on Lenovo 82QF and 82UG
by August Wikerfors 12 Sep '23

12 Sep '23

Like the Lenovo 82TL and 82V2, the Lenovo 82QF (Yoga 7 14ARB7) and 82UG (Legion S7 16ARHA7) both need a quirk entry for the internal microphone to function. Commit c008323fe361 ("ASoC: amd: yc: Fix a non-functional mic on Lenovo 82SJ") restricted the quirk that previously matched "82" to "82V2", breaking microphone functionality on these devices. Fix this by adding specific quirks for these models, as was done for the Lenovo 82TL.

[PATCH v4 00/11] sound: Use -EPROBE_DEFER instead of i915 module loading.
by Maarten Lankhorst 12 Sep '23

12 Sep '23

Explicitly loading i915 becomes a problem when upstreaming the new intel driver for Tiger Lake and higher graphics (xe). By loading i915, it doesn't wait for driver load of xe, and will fail completely before it loads. -EPROBE_DEFER has to be returned before any device is created in probe(), otherwise the removal of the device will cause EPROBE_DEFER to try again in an infinite loop. The conversion is done in gradual steps. First I add an argument to snd_hdac_i915_init to allow for -EPROBE_DEFER so I can convert each driver separately. Then I convert each driver to move snd_hdac_i915_init out of the workqueue. Finally I drop the ability to choose modprobe behavior after the last user is converted. Compared to previous version, I picked up Pierre's changes to add a probe_no_wq, added remove_no_wq myself and then fixed the SOF changes to use it.

by Peter Ujfalusi 12 Sep '23

It could be done by limiting the range in sprintf like sprintf(name, "card%d", idx % SNDRV_CARDS); sprintf(name, "card%hhd", idx); etc These are too workaroundish. Increase the name array to 15 instead which looks better and only adds 7 bytes on stack.

[PATCH] ALSA: seq: Avoid delivery of events for disabled UMP groups
by Takashi Iwai 12 Sep '23

12 Sep '23

ALSA sequencer core still delivers events to the disabled UMP Group, leaving this handling to the device. But it's rather risky and it's easy to imagine that such an unexpected event may screw up the device firmware. This patch avoids the superfluous event deliveries by setting the group_filter of the UMP client as default, and evaluate the group_filter properly at delivery from non-UMP clients. The grouop_filter is updated upon the dynamic UMP Function Block updates, so that it follows the change of the disabled UMP Groups, too.
