[PATCH v4 1/2] ALSA: hda/tas2781: Add tas2781 HDA driver
by Shenghao Ding 18 Aug '23

18 Aug '23

Integrate tas2781 configs for Lenovo Laptops. All of the tas2781s in the laptop will be aggregated as one audio device. The code support realtek as the primary codec. Rename "struct cs35l41_dev_name" to "struct scodec_dev_name" for all other side codecs instead of the certain one. Signed-off-by: Shenghao Ding <shenghao-ding(a)ti.com> --- Changes in v4: - | Reported-by: kernel test robot <lkp(a)intel.com> | Closes: | https://lore.kernel.org/oe-kbuild-all/202308172137.SthCPFbA-lkp@intel. | com/ - remove workaround code for 0x17aa38be, laptop vendor will fix it in acpi. - rename comp_match_tas2781_dev_name to avoid indentation - simplify the check of vendor id with Lenovo - ThinkPad is one of Lenovo's brands, I was suggested me to use ALC269_FIXUP_THINKPAD_ACPI. - Add comments on ACARD_SINGLE_RANGE_EXT_TLV - Add the range check for tas_priv->tasdevice[] in tas2781_acpi_get_i2c_res. - remove acpi_subsystem_id - Issue in Laptop 0x17aa38be ACPI talbe caused codec->bus->pci->subsystem_device is not equal to (codec->core.subsystem_id & 0xffff) in snd_hda_pick_fixup. The former is 0x3802 and the latter is 0x38be leads to getting the wrong fixup_id and enter into the wrong entry. Although, this issue has been raised to the laptop manufacturer, but the ACPI table is locked, cannot be changed any more. Correct the wrong entry in the code. - Rename "struct cs35l41_dev_name" to "struct scodec_dev_name" for all other side codecs instead of one certain codec. - Ignore the checkpatch complaints in alc269_fixup_tbl - Drop the hunk which is irrelevant with my code in alc_fixup_headset_mode_alc255_no_hp_mic - Add tiwai(a)suse.de into Cc list - remove useless index - combine ALC287_FIXUP_TAS2781_I2C_2 and ALC287_FIXUP_TAS2781_I2C_4 together as ALC287_FIXUP_TAS2781_I2C, The code view all the tas2781s in the laptop as one instance. - delete the white space at the end of the line in alc_fixup_headset_mode_alc255_no_hp_mic --- sound/pci/hda/patch_realtek.c | 88 +++++++++++++++++++++++++++++++++-- 1 file changed, 85 insertions(+), 3 deletions(-) diff --git a/sound/pci/hda/patch_realtek.c b/sound/pci/hda/patch_realtek.c index 44fccfb93cff..ba1b02ed184a 100644 --- a/sound/pci/hda/patch_realtek.c +++ b/sound/pci/hda/patch_realtek.c @@ -6721,7 +6721,7 @@ static void comp_generic_playback_hook(struct hda_pcm_stream *hinfo, struct hda_ } } -struct cs35l41_dev_name { +struct scodec_dev_name { const char *bus;

[PATCH] ASoC: amd: acp: Add kcontrols and widgets per-codec in common code
by Alper Nebi Yasak 18 Aug '23

18 Aug '23

Commit 7ac3404c2e21 ("ASoC: amd: acp: Map missing jack kcontrols") adds card kcontrols and DAPM widgets corresponding to jacks for Headphone and Headset Mic. But these were already being added in acp-legacy-mach.c and acp-sof-mach.c, so this causes a probe error: sof_mach rt5682s-hs-rt1019: control 2:0:0:Headphone Jack Switch:0 is already present sof_mach rt5682s-hs-rt1019: ASoC: Failed to add Headphone Jack Switch: -16 sof_mach rt5682s-hs-rt1019: devm_snd_soc_register_card(sof-rt5682s-hs-rt1019) failed: -16 sof_mach: probe of rt5682s-hs-rt1019 failed with error -16 Removing the new duplicates from the common code might be enough to fix the issue. But some of the codecs use different kcontrols and widgets. NAU8821 alone has an "Int Mic". MAX98360A has a single "Spk", while RT1019 has "Left Spk" and "Right Spk" (and two codec instances with name prefixes). Since there are per-codec differences, add the kcontrols and widgets in the common code as each dai-link is being initialized, instead of in the two machine drivers' probe(). Also, MAX98388 has Left and Right instances, but uses a single "SPK" widget. That seems weird, so normalize it to use two widgets (one per each instance like RT1019) while we're adding controls.

[PATCH] ASoC: rt5645: improve the depop sequences of CBJ detection
by shumingf＠realtek.com 18 Aug '23

18 Aug '23

From: Shuming Fan <shumingf(a)realtek.com> This patch will improve the depop function of CBJ detection before the headphone playback when the system resumes. We also want to complete the CBJ detection in the system-level resume function. It could avoid triggering the detection at the playing state of headphones.

[PATCH v3 0/9] sound: Use -EPROBE_DEFER instead of i915 module loading.
by Maarten Lankhorst 18 Aug '23

18 Aug '23

From: Maarten Lankhorst <dev(a)lankhorst.se> 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. I suspect the avs and skylake drivers used snd_hdac_i915_init purely for the modprobe, but I don't have the hardware to test if it can be safely removed. It can still be done easily in a followup patch to simplify probing. --- Changes since previous version: - Keep the workqueue for soc/sof/intel, instead only move out snd_hdac_i915_init. (Patch 8/9) Rest of patches unchanged.

It only gets called when the jack > is not inserted. Hi Postevca, I just reproduced the bug on my side. You are right that when jack inserted, the codec driver will never enter SND_SOC_BIAS_OFF or suspend or resume. This makes sense because the codec needs micbias power to detect button. Problem is that ALSA or dapm thought the codec power is on during suspend, but the system power is turned off and the registers are reset. The system power is controlled by EC and neither dapm or codec driver can do anything about it. The system power is just turned off. Disabling the jack detection before suspend is ok because the system stops working during suspend anyway. Maybe a detailed comment is needed to explain why?

[PATCH RFC 0/6] ALSA: Fix UAF with delayed kobj release
by Takashi Iwai 18 Aug '23

18 Aug '23

Hi, this is a test patch set for addressing the UAF problems with delayed kobj releases reported by Curtis: https://lore.kernel.org/r/20230801171928.1460120-1-cujomalainey@chromium.org The patch introduced a simple helper for allocating memory with a refcount, and converts the card object, control, PCM and compress objects with the new type. With the refcount, the actual memory release is delayed until all referrer are gone. It's just a RFC and only lightly tested. I myself am not sure whether this is the best way to go. It might be better to take Curtis' approach, just converting the device to its own allocation, too. (But I don't know whether Curtis' patch set covers all cases -- can still be a UAF of card_dev due to devres vs kobj release?) thanks, Takashi === Takashi Iwai (6): ALSA: core: Introduced referenced memory allocator ALSA: core: Fix potential UAF by delayed kobject release of card_dev ALSA: core: Associate memory reference with device initialization ALSA: pcm: Release memory with reference ALSA: control: Reference card by ctl_dev ALSA: compress: Reference card by the device include/sound/core.h | 7 ++- sound/core/compress_offload.c | 2 +- sound/core/control.c | 2 +- sound/core/hwdep.c | 2 +- sound/core/init.c | 105 +++++++++++++++++++++++++++------ sound/core/pcm.c | 6 +- sound/core/rawmidi.c | 2 +- sound/core/seq/seq_clientmgr.c | 2 +- sound/core/timer.c | 2 +- 9 files changed, 101 insertions(+), 29 deletions(-) -- 2.35.3
