78daea29f2 ALSA: hda - Apply codec delay to wallclock.
For playback add the codec-side delay to the timestamp, for capture
subtract it.  This brings the timestamps in line with the time that
was recently added to the delay reporting.

21229613ef ALSA: hda - Introduce get_delay codec PCM ops
Add a new codec PCM ops, get_delay(), to obtain the codec/stream-
specific PCM delay count.  When it's NULL, nothing changes.

This new feature was requested for CA0132, which has significant
delays in the path depending on the running DSP code.

8fc24426f1 Revert "ALSA: hda - Allow power_save_controller option override DCAPS"
This reverts commit 6ab317419c.

The commit [6ab317419c: ALSA: hda - Allow power_save_controller option
override DCAPS] changed the behavior of power_save_controller so that
it can override the driver capability.  This assumed that this option
is rarely changed dynamically unlike power_save option.  Too naive.

It turned out that the user-space power-management tool tries to set
power_save_controller option to 1 together with power_save option
without knowing what's actually doing.  This enabled forcibly the
runtime PM of the controller,  which is known to be broken om many
chips thus disabled as default.

So, the only sane fix is to revert this commit again.  It was intended
to ease debugging/testing for runtime PM enablement, but obviously we
need another way for it.

eb49faa6a4 ALSA: hda - Fix abuse of snd_hda_lock_devices() for DSP loader
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.

9ddf1aeb21 ALSA: hda - Fix non-snoop page handling
For non-snoop mode, we fiddle with the page attributes of CORB/RIRB
and the position buffer, but also the ring buffers.  The problem is
that the current code blindly assumes that the buffer is contiguous.
However, the ring buffers may be SG-buffers, thus a wrong vmapped
address is passed there, leading to Oops.

This patch fixes the handling for SG-buffers.

cc5ede3efd ALSA: hda - Check validity of CORB/RIRB WP reads
When the HD-audio controller is disabled (e.g. via vga switcheroo) but
the driver is still accessing it, it spews floods of "spurious
response" kernel messages.  It's because CORB/RIRB WP reads 0xff, and
the driver tries to fill up until this number.

This patch changes the CORB/RIRB WP reads to word instead of byte, and
add the check of the read value.  If it's 0xffff, the controller is
supposed to be disabled, so the further action will be skipped.

f4c482a4d0 ALSA: hda - Fix yet another race of vga_switcheroo registration
The recent fix for vga switcheroo race in commit 128960a9 opened yet
another race.  At the time the audio driver starts probing, user may
turn off D-GPU off.  But at this moment, the audio driver still
doesn't register the vga switcheroo client, thus the switching isn't
notified.  Then the hardware gets off out of sudden, resulting in
invalid reads and lots of "spurious response" error messages.

For solving this situation, the following changes have been done in
this patch:
- Move again vga switcheroo registration to the very early stage of
  the probing; this also requires to set pci drvdata properly before
  registration
- Introduce the completion to synchronize the driver probe at vga
  switcheroo callbacks; this assures that the whole probing finished
  before executing the callbacks

915bf29eb9 ALSA: hda - Avoid BDL position workaround when no_period_wakeup is set
Originally the bogus period at BDL head was introduced as a workaround
for the mismatching position update at the period boundary, typically
seen on dmix.  However, for applications like PulseAudio that don't
require period wake ups, this workaround is just superfluous.  Thus
better to disable it when no_period_wakeup is given in hw_params.

Commit c20c5a841c changed some chipsets to
default to POS_FIX_COMBO so they now use POS_FIX_LPIB instead of
POS_FIX_POSBUF. Since then I've been getting artifacts on playback, including
repeated sounds on my Asus laptop.

My hardware is Cougar Point which the commit log of

probably works in general but apparently it doesn't on Asus K53E therefore the

b8dfc46241 ALSA: hda - add runtime PM support
Runtime PM can bring more power saving:
- When the controller is suspended, its parent device will also have a chance
  to suspend.
- PCI subsystem can choose the lowest power state the controller can signal
  wake up from. This state can be D3cold on platforms with ACPI PM support.
And runtime PM can provide a gerneral sysfs interface for a system policy
manager.

Runtime PM support is based on current HDA power saving implementation. The user
can enable runtime PM on platfroms that provide acceptable latency on transition
from D3 to D0.

Details:
- When both power saving and runtime PM are enabled:
  -- If a codec supports 'stop-clock' in D3, it will request suspending the
     controller after it enters D3 and request resuming the controller before
     back to D0. Thus the controller will be suspended only when all codecs are
     suspended and support stop-clock in D3.
  -- User IO operations and HW wakeup signal can resume the controller back to
     D0.
- If runtime PM is disabled, power saving just works as before.
- If power saving is disabled, the controller won't be suspended because the
  power usage counter can never be 0.

More about 'stop-clock' feature:
If a codec can support targeted pass-through operations in D3 state when there
is no BCLK present on the link, it will set CLKSTOP flag in the supported power
states and report PS-ClkStopOk when entering D3 state. Please refer to HDA spec
section 7.3.3.10 Power state and 7.3.4.12 Supported Power State.

b4a91cf05c ALSA: hda - Handle open while transitioning to D3.
This addresses an issue encountered when a pcm is opened while
transitioning to low power state (codec->power_on == 1 &&
codec->power_transition == -1).  Add snd_pcm_power_up_d3wait to
hda_codec.  This function is used to power up from azx_open as opposed
to snd_hda_power_up used from codec_exec_verb. When powering up from
azx_open, wait for pending power downs to complete, avoiding the power
up continuing in parallel with the power down on the work queue.

The specific issue seen was with the CS4210 codec, it powers off the ADC
and DAC nid in its suspend handler.  If it is re-opened before the
~100ms power down process completes, the ADC and DAC nid are initialized
while powered down and audio is lost until another suspend/resume cycle.

with the default VGA device.  This is the culprit.

Now with the new vga_switcheroo_get_client_state(), we can know the

When an IRQ for some reason gets lost, we wait up to a second using
udelay, which is CPU intensive. This patch improves the situation by
waiting about 30 ms in the CPU intensive mode, then stepping down to
using msleep(2) instead. In essence, we trade some granularity in
exchange for less CPU consumption when the waiting time is a bit longer.

As a result, PulseAudio should no longer be killed by the kernel
for taking up to much RT-prio CPU time. At least not for *this* reason.

7f30830b7b ALSA: hda - Always resume the codec immediately
This is a fix for the problem in commit 785f857d1c, the pop noise
issue on some machines with ALC269.  The problem was the uninitialized
state after the resume due to the delayed resume of the codec chips.
In that commit, we tried to fix by forcibly putting the codec to D3 at
suspend.  But, this still also leaves the uninitialized state after
resume, and it _might_ be still problematic with some BIOS.  Since the
commit turned out to regress another issues, we reverted it in the
end.

Now, in this fix, try to fix by turning on the codec immediately at
the resume path.  We need to take care of the power-saving in this
case.  When the device is woken up at the power-saved state, it should
go power-saving again after the resume.

619a341b78 Revert "ALSA: hda - Set codec to D3 forcibly even if not used"
This reverts commit 785f857d1c.

The commit causes a problem with the wrong D3 state after suspend
because the call of hda_set_power_state() involves with the power-up
sequence, which changes the power_count, and this confuses the resume
sequence that checks the power_count as well.

Originally, this go-to-D3 sequence should be a simple task without the
power-up sequence.  But, it'd need some proper sanity checks in the
case of power-saved state, so it's not too easy to write now in the
3.4-rc cycle.

In short, the safest option now is to revert this affecting commit.

Of course, we need to clean up and robustify the power-saving code
better for 3.5 kernel.

785f857d1c ALSA: hda - Set codec to D3 forcibly even if not used
We've seen a problem with a pop-noise at suspend/resume on a HP
machine with ALC269, and it turned out to be an issue that the
controller going to D3 while the codec is unused.

When the device is once suspended and resumed and kept unused, the
driver doesn't initialize the codecs.  Instead, the codec chips are
set up dynamically at the first usage.  Now, suppose the device going
to suspend again before the codec is set up.  The controller is turned
off to D3 while the codec chips are untouched.  This caused a pop
noise because the codec chip might have been turned on implicitly by
the hardware.

As a workaround, the codec chip needs to be set to D3 when going to
suspend no matter whether it was used or not.  Also, for making it
happening, the controller has to be always set up in the resume path.

7bfe059e38 ALSA: hda - explicitly set buffer-align flag for Nvidia controllers
It turned out that Nvidial (HDMI) controllers require the buffer
alignment.  Thus it's better to mark it requiring the alignment, so that
we can switch to non-aligned behavior as default in future.

Also, change the module paramter to be bint, in order to let user

52409aa6a0 ALSA: hda - Fix buffer-alignment regression with Nvidia HDMI
The commit 2ae66c2655
    ALSA: hda: option to enable arbitrary buffer/period sizes
introduced a regression on machines with Intel controller and Nvidia
HDMI.  The reason is that the driver modifies the global variable
align_buffer_size when an Intel controller is found, and the Nvidia
HDMI controller is probed after Intel although Nvidia chips require
the aligned buffers.

This patch fixes the problem by moving the flag into the local struct
so that it's not affected by other controllers.

4f8b6c7dc8 ALSA: hda_intel - revert a quirk that affect VIA chipsets
This quirk sould be reverted. It has the following probems:

1) The quirk was intended to "ASUS MV2-MX SE" motherboards only, but the
ID used matches a much broader range, potentially all boards containing a
VIA chipset model in the family of vendor VIA 0x1106 and audio device ID
0x3288, which encompasses VIA-VT82xx, VIA-VT1xx and VIA-VT20xx chipsets.

2) VIA chipsets rely on azx_via_get_position() to handle correctly dma
transfers during capture. Using POS_FIX_LPIB instead of POS_FIX_VIACOMBO
leads to partially corrupted input buffers during capture. The effects
of this bug are not immediately visible, it took strong DSP expertise,
some expensive signal generator and a spectrum analyzer to identify it
and verify correct behaviour using original default.

3) It's almost certain that the quirk did not fix the real problem,
if there was one. Refer to original submission:

27fe48d972 ALSA: hda - Add snoop option
Added a new option "snoop" for the traffic control of the HD-audio
controller chip.  When set to 0, the non-snooping mode is used with
the traffic control bit is set in each stream control register.
This may allow better operations in the low power mode, but the actual
implementation is depending pretty much on the chipset.

As already implemented, more or less each chipset has own snoop-control
register bit.  Now this setup refers to the snoop option, too.

Also, a new VIA chipset may require the non-snooping mode when set so
in BIOS.  In such a case, the option value is overridden.

As default, it's still set to snoop=1 for keeping the same behavior as
before.  In near future, it'll be set to 0 as default after checking
it works in every system well.

7c93597627 ALSA: hda: Allow multple SPDIF controls per codec
Currently, the data that backs the kcontrols created by
snd_hda_create_spdif_out_ctls is stored directly in struct hda_codec. When
multiple sets of these controls are stored, they will all manipulate the
same data, causing confusion. Instead, store an array of this data, one
copy per converter, to isolate the controls.

This patch would cause a behavioural change in the case where
snd_hda_create_spdif_out_ctls was called multiple times for a single codec.
As best I can tell, this is never the case for any codec.

This will be relevant at least for some HDMI audio codecs, such as the
NVIDIA GeForce 520 and Intel Ibex Peak. A future change will modify the
driver's handling of those codecs to create multiple PCMs per codec. Note
that this issue isn't affected by whether one creates a PCM-per-converter
or PCM-per-pin; there are multiple of both within a single codec in both
of those codecs.

Note that those codecs don't currently create multiple PCMs for the codec
due to the default HW mux state of all pins being to point at the same
converter, hence there is only a single converter routed to any pin, and
hence only a single PCM.

Commit 9477c58e33 ("ALSA: hda - Reorganize controller quriks with bit

However, the check for AZX_DCAPS_NO_TCSEL got reverted: instead of
clearing TCSEL for chipsets that have that standard capability, it
cleared then when the NO_TCSEL bit was set.

This can lead to noise and repeated sounds - a weird "echo" behavior.
As the comment just above says: "Ensuring these bits are 0 clears
playback static on some HD Audio codecs".  Which is definitely true at
least on my Core i5 Westmere system.

beaffc3993 ALSA: hda - Fixes distorted recording on US15W chipset
The HDA controller in US15W (Poulsbo) reports inaccurate position values
for capture streams when using the LPIB read method, resulting in
distorted recordings.

However, using the position buffer is broken for playback streams,
resulting in a fallback to the LPIB method with the current driver.
This patch works around the issue by independently detecting the read
position method for capture and playback streams.

The patch will not have any effect if the position fix method is
explicitly set.

the DMA position problem is revealed more clearly now.

The fix is to use only LPIB for obtaining the position, i.e. passing
position_fix=1.  This patch adds a static quirk to achieve it as default.

0a27fcfaaf ALSA: hda - Correct ASUA blacklist for MSI brokenness
The MSI blacklist entry for ASUS mobo added in the commit
8ce28d6abf was based on the alsa-info
output wrongly posted.  Fix the id to the right one now.

d6d8bf5493 ALSA: hda - use WARN_ON_ONCE() for zero-division detection
Replace the zero-division warning message with WARN_ON_ONCE() per the
advice by Linus.  This shouldn't happen, but if it happens, it's
possible that the bug happens often due to buggy IRQs.

fed08d036f ALSA: hda-intel: Avoid divide by zero crash
On my AMD780V chipset, hda_intel.c can crash the kernel with a divide by
zero
for as-yet unknown reasons. A simple check for zero prevents it, though
the problem that causes it remains. Since the workaround is harmless and
won't affect anyone except victims of this bug, it should be safe;
moreover,
because this crash can be triggered by a user-mode application, there are
denial of service implications on the systems affected by the bug without
the patch.
