      ALSA: hda - Fix abuse of snd_hda_lock_devices() for DSP loader · eb49faa6
      由 Takashi Iwai 提交于 
      The current DSP loader code abuses snd_hda_lock_devices() for ensuring
the DSP loader not conflicting with the other normal operations.  But
this trick obviously doesn't work for the PM resume since the streams
are kept opened there where snd_hda_lock_devices() returns -EBUSY.
That means we need another lock mechanism instead of abuse.

This patch provides the new lock state to azx_dev.  Theoretically it's
possible that the DSP loader conflicts with the stream that has been
already assigned for another PCM.  If it's running, the DSP loader
should simply fail.  If not -- it's the case for PM resume --, we
should assign this stream temporarily to the DSP loader, and take it
back to the PCM after finishing DSP loading.  If the PCM is operated
during the DSP loading, it should get an error, too.

      ALSA: hda - Fix snd_hda_get_num_raw_conns() to return a correct value · b5f82b10
      由 Takashi Iwai 提交于 
      In the connection list expansion in hda_codec.c and hda_proc.c, the
value returned from snd_hda_get_num_raw_conns() is used as the array
size to store the connection list.  However, the function returns
simply a raw value of the AC_PAR_CONNLIST_LEN parameter, and the
widget list with ranges isn't considered there.  Thus it may return a
smaller size than the actual list, which results in -ENOSPC in
snd_hda_get_raw_conections().

This patch fixes the bug by parsing the connection list correctly also
for snd_hda_get_num_raw_conns().

      ALSA: hda - Increase badness for missing multi-io · 1d739066
      由 Takashi Iwai 提交于 
      The current badness value used for the missing multi-io seems too
weak, and the multi-io tends to be skipped for desktop configurations
when no enough DACs are available.  It's because the total badness of
the multi-io becomes often larger than the badness with assigning an
individual DAC to a headphone jack.  This is good for one side, but it
seems that the surround outputs are more demanded by that.

This patch increases the badness value for the missing multi-io
slightly so that the multi-io would be preferred than the individual
headphone DAC if they conflict.  Through the tests with hda-emu,
mostly only desktop configurations with ALC662/663 and CMI codecs are
affected by this change, and all look reasonable.

      ALSA: hda - Fix broken workaround for HDMI/SPDIF conflicts · ea9b43ad
      由 Takashi Iwai 提交于 
      The commit [dcda5806: ALSA: hda - Add workaround for conflicting
IEC958 controls] introduced a workaround for cards that have both
SPDIF and HDMI devices for giving device=1 to SPDIF control elements.
It turned out, however, that this workaround doesn't work well -

- The workaround checks only conflicts in a single codec, but SPDIF
  and HDMI are provided by multiple codecs in many cases, and

- ALSA mixer abstraction doesn't care about the device number in ctl
  elements, thus you'll get errors from amixer such as
  % amixer scontrols -c 0
  ALSA lib simple_none.c:1551:(simple_add1) helem (MIXER,'IEC958
  Playback Switch',0,1,0) appears twice or more
  amixer: Mixer hw:0 load error: Invalid argument

This patch fixes the previous broken workaround.  Instead of changing
the device number of SPDIF ctl elements, shift the element indices of
such controls up to 16.  Also, the conflict check is performed over
all codecs found on the bus.

HDMI devices will be put to dev=0,index=0 as before.  Only the
conflicting SPDIF device is moved to a different place.  The new place
of SPDIF device is supposed by the updated alsa-lib HDA-Intel.conf,
respectively.

      ALSA: hda - Yet another fix for broken HSW HDMI pin connections · c88d4e84
      由 Takashi Iwai 提交于 
      A Haswell test machine showed that the invalid connection list, but
this time it has only a single pin on the codec, thus the former fixup
code doesn't work as it assumes the three pins blindly.

This patch splits the former fixup code to two parts:
- Enable eDP 1.2 for Haswell codec
- Fix the connection list of pins on Haswell codec;
  the converter list is recorded dynamically in hdmi_add_cvt(), and
  applied in hdmi_add_pin()

      ALSA: hda - Add fixup for Haswell to enable all pin and convertor widgets · 1611a9c9
      由 Mengdong Lin 提交于 
      Some Haswell machines support more than one display outputs (HDMI or DP),
but its BIOS may not enable the codec's 2nd and 3rd pin and output cvt widgets.

This patch implements a board-specific fixup for Intel Haswell Machines:
If the hidden pins are not enabled by BIOS, the driver will enable them
and call common code to update the codec tree.

      ALSA: hda - Support rereading widgets under the function group · a15d05db
      由 Mengdong Lin 提交于 
      A codec may allow software to hide some unused pin/cvt widgets.

Sometimes BIOS does not enable the hidden widgets properly although they are
needed for the board. Thus the driver need to enable them as a board-specific
fixup and the whole tree will change.

This patch implements a common code for rereading codec widgets. So the fixup
code can call it after enabling the hidden widgets.

      ALSA: hda - Remove limit of widget connections · 4eea3091
      由 Takashi Iwai 提交于 
      Currently we set the max number of connections to be 32, but there
seems codec that gives longer connection lists like AD1988, and we see
errors in proc output and else.  (Though, in the case of AD1988, it's
a list of all codecs connected to a single vendor widget, so this must
be something fishy, but it's still valid from the h/w design POV.)

This patch tries to remove this restriction.  For efficiency, we still
use the fixed size array in the parser, but takes a dynamic array when
the size is reported to be greater than that.

Now the fixed array size is found only in patch_hdmi.c, but it should
be fine, as the codec itself can't support so many pins.
