ALSA: pcm: Add big-endian DSD sample formats and fix XMOS DSD sample format

2014-11-21T14:13:28+00:00

This patch fixes XMOS DSD sample format to DSD_U32_BE and also adds
DSD_U16_BE and DSD_U32_BE sample formats.

ALSA: pcm: Zero-clear reserved fields of PCM status ioctl in compat mode

2014-10-28T11:45:53+00:00

In compat mode, we copy each field of snd_pcm_status struct but don't
touch the reserved fields, and this leaves uninitialized values
there.  Meanwhile the native ioctl does zero-clear the whole
structure, so we should follow the same rule in compat mode, too.

ALSA: pcm: Fix false lockdep warnings

2014-10-21T16:17:02+00:00

As PCM core handles the multiple linked streams in parallel, lockdep
gets confused (partly because of weak annotations) and spews the
false-positive warnings.  This hasn't been a problem for long time but
the latest PCM lock path update seems to have woken up a sleeping
dog.

Here is an attempt to paper over this issue: pass the lock subclass
just calculated from the depth in snd_pcm_action_group().  Also, a
(possibly) wrong lock subclass set in snd_pcm_action_lock_mutex() is
dropped, too.

ALSA: pcm: use the same dma mmap codepath both for arm and arm64

2014-10-18T09:11:23+00:00

This avoids following kernel crash when try to playback on arm64

[  107.503405] [] __do_fault+0xb0/0x498

[  107.519738] [] do_mem_abort+0x38/0x98

Tested: backported to 3.14 and tried to playback on arm64 machine

ALSA: pcm: Fix referred substream in snd_pcm_action_group() unlock loop

2014-10-14T07:14:48+00:00

In the unlock loop of snd_pcm_action_group(), the object "s" is used
as the check of nonatomic PCM, but it should be rather "s1", which is
the iterator of the loop.  This supposedly causes a kernel panic when
the substreams in operatino are linked.

ALSA: Allow pass NULL dev for snd_pci_quirk_lookup()

2014-10-08T10:08:38+00:00

Add a NULL check in snd_pci_quirk_lookup() so that NULL can be passed
as a pci_dev pointer.  This fixes the possible NULL dereferences in
HD-audio drivers.

Merge tag 'asoc-v3.18' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-next

2014-10-06T12:01:11+00:00

ASoC: Updates for v3.18

 - More componentisation work from Lars-Peter, this time mainly
   cleaning up the suspend and bias level transition callbacks.
 - Real system support for the Intel drivers and a bunch of fixes and
   enhancements for the associated CODEC drivers, this is going to need
   a lot quirks over time due to the lack of any firmware description of
   the boards.
 - Jack detect support for simple card from Dylan Reid.
 - A bunch of small fixes and enhancements for the Freescale drivers.
 - New drivers for Analog Devices SSM4567, Cirrus Logic CS35L32, Everest
   Semiconductor ES8328 and Freescale cards using the ASRC in newer i.MX
   processors.

ALSA: pcm: fix fifo_size frame calculation

2014-09-22T06:51:35+00:00

The calculated frame size was wrong because snd_pcm_format_physical_width()
actually returns the number of bits, not bytes.

Use snd_pcm_format_size() instead, which not only returns bytes, but also
simplifies the calculation.

Merging for-linus branch for syncing the latest STAC/IDT codec
changes to be affected by the upcoming hda-jack rewrites.

ALSA: pcm: add new DSD sampleformat for native DSD playback on XMOS based devices

2014-09-08T15:11:00+00:00

XMOS based USB DACs with native DSD support expose this feature via a USB
alternate setting. The audio format is either 32-bit raw or a 32-bit PCM format.
To utilize this feature on linux this patch introduces a new 32-bit DSD
sampleformat DSD_U32_LE.
A follow up patch will add a quirk for XMOS based devices to utilize the new format.
Further patches will add support to alsa-lib.
