Takashi Iwai [Fri, 6 Sep 2013 13:45:38 +0000 (15:45 +0200)]
ALSA: hda - Add dock speaker support for ASUS TX300

ASUS TX300 has a built-in speaker in the tablet part and in the dock
part, and the tablet speaker is supposed to be unused while the
machine is docked.  The current HD-audio driver, however, doesn't
support the dock speaker, partly because BIOS doesn't set up the pin
for the corresponding output.

But, not only the missing pin config, also the missing unsol event
handling is another issue.  Otherwise the automatic switching via
dock/undock won't work.

Through debugging sessions, we found out that the dock speaker pin is
NID 0x1b, and it generates an unsol event at docking/undocking, the
docking state can be inquired via the normal pin detection verb.
Also, it's turned out that GPIO 2 is needed as an amp.  So, all
materials are ready to cook.

This patch provides the basic dock speaker support with TX300:
- The dock speaker is turned on/off via "Dock Speaker" mixer mute.
- The dock speaker is automatically muted when docked.  This is
  independently from the mixer mute switch, just like the headphone
  auto-mute function.

The implementation is a bit tricky.  Since we want to handle it as a
secondary speaker, we set it up a pin as a speaker with a jack
detection.  Then, the fixup function registers the own unsol callback
for this pin because the standard automute can't handle the thing like
a "speaker jack".  In the own automute hook, we apply the mute of the
tablet speaker in addition by checking the dock state.

Also, the speaker control names are slightly shuffled because the
generic parser doesn't give good names but blindly assumes a bass
speaker as a secondary speaker.

Takashi Iwai [Mon, 2 Sep 2013 10:33:02 +0000 (12:33 +0200)]
ALSA: hda - Re-setup HDMI pin and audio infoframe on stream switches

When the transcoder:port mapping on Haswell HDMI/DP audio is changed
during the stream playback, the sound gets lost.  Typically this
problem is seen when the user switches the graphics mode from eDP+DP
to DP-only configuration, where CRTC 1 is used for DP in the former
while CRTC 0 is used for the latter.

The graphics controller notifies the change via the normal ELD update
procedure, so we get the intrinsic event.  For enabling the sound
again, the HDMI audio driver needs to reset the pin and set up the
audio infoframe again.

This patch achieves it by:
- keep the current status of channels and info frame setup in per_pin
  struct,
- check the reconnection in the intrinsic event handler,
- reset the pin and the re-invoke hdmi_setup_audio_infoframe()
  accordingly.

The hdmi_setup_audio_infoframe() function has been changed, too, so
that it can be invoked without passing the substream instance.

The patch is mostly based on the work by Mengdong Lin.

Anssi Hannula [Sun, 1 Sep 2013 11:36:47 +0000 (14:36 +0300)]
ALSA: hda - hdmi: Fallback to ALSA allocation when selecting CA

hdmi_channel_allocation() tries to find a HDMI channel allocation that
matches the number channels in the playback stream and contains only
speakers that the HDMI sink has reported as available via EDID. If no
such allocation is found, 0 (stereo audio) is used.

Using CA 0 causes the audio causes the sink to discard everything except
the first two channels (front left and front right).

However, the sink may be capable of receiving more channels than it has
speakers (and then perform downmix or discard the extra channels), in
which case it is preferable to use a CA that contains extra channels
than to use CA 0 which discards all the non-stereo channels.

Additionally, it seems that HBR (HD) passthrough output does not work on
Intel HDMI codecs when CA is set to 0 (possibly the codec zeroes
channels not present in CA). This happens with all receivers that report
a 5.1 speaker mask since a HBR stream is carried on 8 channels to the
codec.

Add a fallback in the CA selection so that the CA channel count at least
matches the stream channel count, even if the stream contains channels
not present in the sink speaker descriptor.

Thanks to GrimGriefer at OpenELEC forums for discovering that changing
the sink speaker mask allowed HBR output.

drivers/platform/olpc/olpc-ec.c: initialise earlier

Being a low-level component, various drivers (e.g.  olpc-battery) assume
that it is ok to communicate with the OLPC Embedded Controller during
probe.  Therefore the OLPC EC driver must be initialised before other
drivers try to use it.  This was the case until it was recently moved
out of arch/x86 and restructured around commits ac2504151f5a ("Platform:
OLPC: turn EC driver into a platform_driver") and 85f90cf6ca56 ("x86:
OLPC: switch over to using new EC driver on x86").

Use arch_initcall so that olpc-ec is readied earlier, matching the
previous behaviour.

Fixes a regression introduced in Linux-3.6 where various drivers such as
olpc-battery and olpc-xo1-sci failed to load due to an inability to
communicate with the EC.  The user-visible effect was a lack of battery
monitoring, missing ebook/lid switch input devices, etc.

Revert "genetlink: fix family dump race"

This reverts commit 58ad436fcf49810aa006016107f494c9ac9013db.

It turns out that the change introduced a potential deadlock
by causing a locking dependency with netlink's cb_mutex. I
can't seem to find a way to resolve this without doing major
changes to the locking, so revert this.

Revert "x86 get_unmapped_area(): use proper mmap base for bottom-up direction"

This reverts commit df54d6fa54275ce59660453e29d1228c2b45a826.

The commit isn't necessarily wrong, but because it recalculates the
random mmap_base every time, it seems to confuse user memory allocators
that expect contiguous mmap allocations even when the mmap address isn't
specified.

In particular, the MATLAB Java runtime seems to be unhappy. See

  https://bugzilla.kernel.org/show_bug.cgi?id=60774

So we'll want to apply the random offset only once, and Radu has a patch
for that.  Revert this older commit in order to apply the other one.
