2018-08-30T14:45:10Z

ALSA: hda/hdmi - Don't fall back to generic when i915 binding fails

2018-06-28T11:36:54Z

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. Signed-off-by: Takashi Iwai

ALSA: hda: split snd_hda_codec_new function

2018-06-28T05:33:29Z

Split snd_hda_codec_new into two separate functions. snd_hda_codec_device_init allocates memory and registers with bus. snd_hda_codec_device_new initialializes the fields and performs snd_device_new. This enables reuse of legacy HDA codec drivers as ASoC codec drivers. In addition mark some functions with EXPORT_SYMBOL_GPL so that it can be called by ASoC wrapper around the legacy HDA driver (hdac_hda).

ALSA: hda - Kill snd_hda_codec_update_cache()

2018-06-27T09:43:09Z

snd_hda_codec_update_cache() used to serve for a slightly different purpose from snd_hdac_write_cache(), but now both of them became identical. Let's unify and replace with the latter one consistently. Signed-off-by: Takashi Iwai

ALSA: hda - Force to link down at runtime suspend on ATI/AMD HDMI

2018-06-21T11:46:56Z

Henning Kühn reported that the discrete AMD GPU on his hybrid graphics laptop no longer runtime-suspends due to the recent commit 07f4f97d7b4b ("vga_switcheroo: Use device link for HDA controller"). The root cause is that the HDMI codec on AMD GPU doesn't support CLKSTOP and EPSS, which are currently mandatory for powering down the HD-audio link at runtime suspend. Because the HD-audio link is still up, HD-audio controller driver blocks the transition to D3. For addressing the regression, this patch adds a new flag to indicate the forced link-down, and sets it for AMD HDMI codecs appropriately in the codec driver.

ALSA: hda: Fix regression of hdmi eld control created based on invalid pcm

2017-09-03T14:33:42Z

Commit fb087eaaef72 ("ALSA: hda - hdmi eld control created based on pcm") forget to filter out invalid pcm numbers, if there is only one invalid pcm number, then this issue causes we create eld control for invalid pcm silently, but when there are more than one invalid pcm numbers, then this issue bring probe error looks like below dmesg: " kernel: [ 1.647283] snd_hda_intel 0000:00:03.0: bound 0000:00:02.0 (ops 0xc2967540) kernel: [ 1.651192] snd_hda_intel 0000:00:03.0: Too many HDMI devices kernel: [ 1.651195] snd_hda_intel 0000:00:03.0: Consider building the kernel with CONFIG_SND_DYNAMIC_MINORS=y kernel: [ 1.651197] snd_hda_intel 0000:00:03.0: Too many HDMI devices kernel: [ 1.651199] snd_hda_intel 0000:00:03.0: Consider building the kernel with CONFIG_SND_DYNAMIC_MINORS=y kernel: [ 1.651201] snd_hda_intel 0000:00:03.0: Too many HDMI devices kernel: [ 1.651203] snd_hda_intel 0000:00:03.0: Consider building the kernel with CONFIG_SND_DYNAMIC_MINORS=y kernel: [ 1.651676] snd_hda_intel 0000:00:03.0: control 3:0:0:ELD:0 is already present kernel: [ 1.651787] snd_hda_codec_hdmi: probe of hdaudioC0D0 failed with error -16 " This patch add invalid pcm number filter before calling hdmi_create_eld_ctl.

ALSA: hda - Fix endless loop of codec configure

2017-06-28T10:10:05Z

azx_codec_configure() loops over the codecs found on the given controller via a linked list. The code used to work in the past, but in the current version, this may lead to an endless loop when a codec binding returns an error. The culprit is that the snd_hda_codec_configure() unregisters the device upon error, and this eventually deletes the given codec object from the bus. Since the list is initialized via list_del_init(), the next object points to the same device itself. This behavior change was introduced at splitting the HD-audio code code, and forgotten to adapt it here. For fixing this bug, just use a *_safe() version of list iteration.

ALSA: hda - A new flag to enforce prefix to each pin

2017-04-10T15:44:39Z

This is a preliminary patch for a smooth multi-codec support, and it introduces a new flag, force_pin_prefix, to struct hda_codec. This flag is used to force to add the pin location prefix to each input pin. For example, when there is only one microphone pin, usually the auto-parser assigns the string "Mic". With this flag on, it'll be like "Front Mic". Also, the creation of "Master" or "PCM" playback volume for a single pin is suppressed, too.
