[alsa-devel] [PATCH 0/3] ALSA: PM-related fixes/cleanups
by Takashi Iwai 28 Jun '18

28 Jun '18

Hi, this is a patch set addressing some minor issues found in PM-related stuff, as well as the Intel HDMI fallback issue. The first patch covers the unusual error paths from runtime PM, the second one is a code refactoring and the last one fixes the superfluous (rather harmful) binding with the generic HDMI driver as fallback of i915 component binding. Takashi === Takashi Iwai (3): ALSA: hda - Handle error from snd_hda_power_up*() ALSA: hda - Move in_pm accessors to HDA core ALSA: hda/hdmi - Don't fall back to generic when i915 binding fails include/sound/hdaudio.h | 27 +++++++++++++++++ sound/pci/hda/hda_beep.c | 3 +- sound/pci/hda/hda_codec.c | 25 ++++++---------- sound/pci/hda/hda_controller.c | 4 ++- sound/pci/hda/hda_proc.c | 3 +- sound/pci/hda/hda_sysfs.c | 4 ++- sound/pci/hda/patch_ca0132.c | 53 +++++++++++++++++++++++++++------- sound/pci/hda/patch_hdmi.c | 4 ++- sound/pci/hda/patch_realtek.c | 3 +- 9 files changed, 93 insertions(+), 33 deletions(-) -- 2.17.1

[alsa-devel] dsd formats in ALSA plugins
by slava 28 Jun '18

28 Jun '18

Sorry, don't receive my own post, so can't reply Find in alsa-lib-1.1.6 file src/pcm/pcm-params.c line 1945 static const snd_mask_t refine_masks[SND_PCM_HW_PARAM_LAST_MASK - SND_PCM_HW_PARAM_FIRST_MASK + 1] = { [SND_PCM_HW_PARAM_ACCESS - SND_PCM_HW_PARAM_FIRST_MASK] = { .bits = { 0x1f }, }, [SND_PCM_HW_PARAM_FORMAT - SND_PCM_HW_PARAM_FIRST_MASK] = { .bits = { 0x81ffffff, 0xfff}, Change last 0xfff to 0xfffff and now can use DSD formats How i understand, in version 1.0.27 last format = 43 and when new format was added but mask not changed May be i absolutely wrong and what i do has side effects or needed any else? Thanks

[alsa-devel] [PATCH v2] ALSA: hda/hdmi - Don't fall back to generic when i915 binding fails
by Takashi Iwai 28 Jun '18

28 Jun '18

When i915 component binding fails, it means that HDMI isn't applicable anyway. Although the probe with the generic HDMI parser would still work, it's essentially useless, hence better to be left unbound. This patch mimics the probe_id field at failing the i915 component binding so that the generic HDMI won't be bound after that.

[alsa-devel] [PATCH] ALSA: hda - Handle pm failure during hotplug
by Chris Wilson 27 Jun '18

27 Jun '18

Obtaining the runtime pm wakeref can fail, especially in a hotplug scenario where i915.ko has been unloaded. If we do not catch the failure, we end up with an unbalanced pm.

[alsa-devel] [PATCH] ALSA: intel_hdmi: Use strlcpy() instead of strncpy()
by Takashi Iwai 27 Jun '18

27 Jun '18

hdmi_lpe_audio_probe() copies the pcm name string via strncpy(), but as a gcc8 warning suggests, it misses a NUL terminator, and unlikely the expected result. Use the proper one, strlcpy() instead.

[alsa-devel] [PATCH tinycompress] cplay: Stop playback stream at the end

[alsa-devel] [[PATCH 0/9] ASoC: Intel: bytcr_rt5651: Cleanup (input mapping quirks)
by Hans de Goede 27 Jun '18

27 Jun '18

Hi Mark, This series is mainly a cleanup series. In the beginning of the rt5651 machine driver some wrong assumptions were made, such as the headset mic being attached to IN2 (it is on IN3 on the 7 machines I have access to and on all otherwise known machines). And also adding a quirk for a machine with the intmic on IN2, which later got fixed with a new quirk for machines with 2 internal mics on both IN1 and IN2 and moving the one machine with the IN2 quirk over to the new IN1_IN2 quirk, leaving the IN2 quirk as an orphan quirk for non existing hardware. Then I made a similar mistake adding the IN2_HS_IN3 quirk, while I should have used the IN1_HS_IN3 (which itself only exists because the original IN1 quirk has the headset input mapping wrong), TL;DR: it is a bit of a mess due to a number of wrong assumptions about how the inputs where actually routed in the past. This series cleans this all up in small commits / one bit a time and refers the original commit messages in its commit messages. Note patch 10/11 is not a cleanup patch, but is more or less the reason I took a second look at all the quirks. Regards, Hans
