Detailed changelog between 1.0.15rc2 and 1.0.15rc3 releases

alsa-driver

Sound Core

- add empty kthread wrappers
Add empty wrappers for the kthread functions to allow compilation to
succeed. There is no implementation, so one cannot actually use them.
- release 1.0.15rc3
- Disable link with ac97_bus driver for older kernels
The older kernels have no proper support of ac97_bus driver, so let's
simply disable it.
- PC-Speaker driver update
- PCSP_HOOK is no longer needed, removed.
The driver fully moved to hrtimers and the kernel patch is now optional.
- Depend on EXPERIMENTAL in preparation to submit this upstream.
- Remove the built-in software volume control in favour of softvol.
Signed-off-by: Stas Sergeev <stsp@aknet.ru>

ALSA Core

- add empty kthread wrappers
Add empty wrappers for the kthread functions to allow compilation to
succeed. There is no implementation, so one cannot actually use them.
- change return type of pci_save/restore_state wrappers
Change the return type of pci_save/restore_state() from void to int
because it is actually checked in a driver.

AC97 Codec

- Disable link with ac97_bus driver for older kernels
The older kernels have no proper support of ac97_bus driver, so let's
simply disable it.
- Add default values for power-saving as Kconfig options
Added CONFIG_SND_AC97_POWER_SAVE_DEFAULT and CONFIG_SND_HDA_POWER_SAVE_DEFAULT
Kconfig options as the default values for power-saving mode of AC97 and
HD-audio drivers, respectively.
- ac97: YMF743 missing controls support (1/2)
These patches enable some YMF743 controls (Tone/3D/IEC958) that won't
be detected with the current version of ALSA.
The first one contains only cosmetic changes to share a few
YMF753-specific symbols with YMF743.
Signed-off-by: Keita Maehara <maehara@debian.org>
- ac97: YMF743 missing controls support (2/2)
These patches enable a few YMF743 controls (Tone/3D/IEC958) that won't
be detected with the current version of ALSA.
The second one contains following changes:
- A chip-specific SPDIF support for YMF743 (It doesn't have AC97
standard SPDIF registers seen on YMF753).
- The implementation for "IEC958 Playback Source" and "IEC958 Mute"
are identical to the ones for YMF753. But there is no "IEC958 Output
Pin" for YMF743.

AD1848 driver

- ad1848_lib: waiting loops done after cs4231_lib
This patch fixes ad1848_lib waiting loops to be the same as in the cs4231_lib.
Signed-off-by: Krzysztof Helt <krzysztof.h1@wp.pl>

- ad1848: Fix msleep while atomic
Simplest fix.

Acked-by: Rene Herman <rene.herman@gmail.com>
- ad1848: simplify MCE down code
The polling loop to check for ACI to go down was more convoluted than it
needed to be. New loop should be more efficient and it is a lot simpler. The
old loop checked for a timeout before checking for ACI down, which could
result in an erroneous timeout. It's only a failure if the timeout expires
_and_ ACI is still high. There is nothing wrong with the timeout expiring
while the task is sleeping if ACI went low.
A polling loop to check for the device to leaving INIT mode is removed. The
device must have already left init for the previous ACI loop to have finished.

ALSA sequencer

- schedule_timeout() fix for core/seq/seq_instr.c
Replace schedule_timeout() with schedule_timeout_uninterruptible()
to avoid signals in loop.
Signed-off-by: Rene Herman <rene.herman@gmail.com>

Asihpi driver

- alsa-driver: use schedule_timeout_{,un}interruptible.
Replace 3 open-coded implementations of schedule_timout_{,un}interruptible
and use {u,m}secs_to_jiffies.
Signed-off-by: Rene Herman <rene.herman@gmail.com>

BT87x driver

- bt87x: fix detection of generic boards
Add an "unknown" board type so that it is possible to differentiate
between unknown and generic boards.

CMI8788 driver

- cmi8788: prevent autoloading
The snd-cmi8788 driver is too buggy to allow it to load automatically,
so add a module parameter that must be set explicitly before it loads.

CMIPCI driver

- cmipci: fix version 37 detection
Use the proper value for the bit that identifies chip version 37.
- cmipci: update register definitions
Update comments for many register symbols, add some new register
symbols, and rename a few ones.
- cmipci: show more registers in proc file
Show a dump of all registers in the 0x00-0x27 and 0x90-0x93 ranges in
the "cmipci" proc file.
- cmipci: reset the chip when initializing
When the chip is initialized, reset it.
- cmipci: initialize 0x90 registers
Initialize the registers at 0x90 and 0x91 with some undocumented values.
- cmipci: allow 96 kHz playback on non-multichannel rear
Move the code that enables 96 kHz out of the if() that checks for
availability of both DMA channels so that it is enabled even when
another stream is playing on the front channels.
- cmipci: remove 5.0 format
Disallow playback of five channels because the hardware does not support
it (or nobody knows how to do it).
- cmipci: reorganize set_dac_channels()
By reorganizing the code that sets the CHB3DxC bits we can not only
simplify this code but also fix the bug where the CHB3D8C bit was not
reset when playing a stereo stream after a 7.1 stream.
- cmipci: fix lookup of double rates
When using one of the double sampling rates, use half the sample rate to
look up in the rates[] table, otherwise we stumble over the BUG().
- cmipci: clean up struct cmipci_pcm
Remove some unused field from the struct cmipci_pcm, and change the type
of some others to save some space.
- cmipci: fix distortion on rear channels
When playing multichannel data, the rear channels can get distorted if
the last sample of the last played stereo stream was not zero. To avoid
this, add a hack to play a few silence samples after the stream is
stopped.

EMU10K1/EMU10K2 driver

- emu10k1: enable emu1010 only on 2.6 kernels
Disable support for emu1010 on 2.2/2.4 kernels because we have not yet
emulation code for kthread_*.

_interruptible with _uninterruptible in some debug code; it's not waiting
for signals.

I2C cs8427

- Workaround for invalid signature read of CS8427
Reading the signature of CS8427 over SPI/I2C fails on some devices
by mysterious reason. In most cases, however, it succeeds at the
sequential read. So, let's give a second chance to check the signature
again.

MSND driver

- fix request_firmware() calls for 2.4 kernels
Update the patches for wavefront_synth and msnd_pinnacle to use a
different third parameter for request_firmware() on 2.4 kernels.
- alsa-driver: use schedule_timeout_{,un}interruptible.
Replace 3 open-coded implementations of schedule_timout_{,un}interruptible
and use {u,m}secs_to_jiffies.

Opti9xx drivers

- opti9xx: adjust OPL3 FM resource value
The OPTi ISA-PnP chips advertise their OPL4 base at 0x380 (to 0x3f0) through
pnp and put their on-chip OPL3 at +8. The driver assumes the provided
value is the ALBase (OPL3 address) though and checks for an OPL4 at -8,
which means that simply adding 8 to the pnp provides value works to fix
detection of both OPL3 and OPL4.
Problem spotted on 931 and 933 by Krzysztof Helt and confirmed on 924 and
925 (together all OPTi ISA-PnP chips) by me.

- changed python-incdir to python-includes for configure.in

PCM API

- Fix wrong offset calculation in snd_pcm_{read|write}_mmap()
The offset used in snd_pcm_{read|write}_mmap() is not the linear offset
but the offset in a ring buffer. It has to be rounded.

Configuration

- Fix subdevice number to 0 for dmix/dsnoop
The dmix and dsnoop plugins need a fixed substream number instead of
the next-available one (-1) as the default number. Now it's set to 0.
