Most hardwares have limited buffer-descriptor table length. This
also restricts the max buffer size of the sound driver.
For example, snd-hda-intel has 1MB buffer size limit, and this is
because it can have at most 256 BDL entries. For supporting larger
buffers, we need to allocate larger pages even for sg-buffers.
This patch changes the sgbuf allocation code to try to allocate
larger pages first. At each head of the allocated pages, the
number of allocated pages is stored in the lowest bits of the
corresponding entry of the table addr field. This change isn't
visible as long as the driver uses snd_sgbuf_get_addr() helper.
Also, the patch adds a new function, snd_pcm_sgbuf_get_chunk_size().
This returns the size of the chunk on continuous pages starting at
the given position offset. If the chunk reaches to a non-continuous
page, it returns the size to the boundary.

The support for the SB Extigy's remote seems to be broken in all
recent ALSA versions, including 1.0.17. The driver detects the event
correctly, then submits a URB to query the RC code. On the Extigy, the
URB is submitted with a length of 2 bytes. My hardware, however, only
replies with 1 byte, containing the correct RC button code. The
current implementation discards this as being too short. (line 1784 of
usbmixer.c)
This patch specifies a "minimum packet length" in the remote control
configuration. I've left the values for the Audigy 2/Live! the same as
the packet length, as I'm assuming the existing code works with them.
(I don't have the hardware to confirm) This fixes the Extigy RC
support, e.g. for use with Lirc.

Since jack detection requires the input subsystem which may not be
desired on small systems it is not built unless required by a driver
that is being built. Drivers using jack detection should use a pattern
like this:
config SND_FOO
tristate "..."

select SND_JACK if INPUT=y || INPUT=SND
to ensure that the jack detection API is enabled if the input subsystem
is. If the input subsystem is not enabled then a stub version of the
API is provided.

Currently very few systems provide information about jack status to user
space, even though many have hardware facilities to do detection. Those
systems that do use an input device with the existing SW_HEADPHONE_INSERT
switch type to do so, often independently of ALSA.
This patch introduces a standard method for representing jacks to user
space into ALSA. It allows drivers to register jacks for a sound card with
the input subsystem, binding the input device to the card to help user
space associate the input devices with their sound cards. The created
input devices are named in the form "card longname jack" where jack is
provided by the driver when allocating a jack. By default the parent for
the input device is the sound card but this can be overridden by the
card driver.
The existing user space API with SW_HEADPHONE_INSERT is preserved.

Update the CS4270 ALSA device driver to use the new-style I2C interface.
Starting with the 2.6.27 PowerPC kernel, I2C devices that have entries in the
device trees can no longer be probed by old-style I2C drivers. The device
tree for Freescale MPC8610 HPCD has included an entry for the CS4270 since
2.6.25, but that entry was previously ignored by the PowerPC I2C subsystem.
Since that's no longer the case, the best solution is to update the CS4270
driver to a new-style interface, rather than try to revert the behavior of
new PowerPC I2C subsystem.

When changing the sample rate, the CMI8788's master clock output becomes
unstable for a short time. The AK4396 needs the master clock to do SPI
writes, so writing to an AK4396 control register directly after a sample
rate change will garble the value. In our case, this leads to the DACs
being misconfigured to I2S sample format, which results in a wrong
output level and horrible distortions on samples louder than -6 dB.
To fix this, we need to wait until the new master clock signal has
become stable before doing SPI writes.

ALSA: ASoC: Fix double free and memory leak in many codec drivers
ALSA: CA0106 on MSI K8N Diamond PLUS Motherboard
Many SoC audio codec drivers have improper freeing of memory in error
paths.
* codec is allocated in the platform device probe function, but is not
freed there in case of error. Instead it is freed in the i2c device
probe function's error path. However the success or failure of both
functions is not linked, so this could result in a double free (if
the platform device is successfully probed, the i2c device probing
fails and then the platform driver is unregistered.)

functions but not freed in their error paths.

The Freescale MPC8610 SSI device has the option of using one clock for both
transmit and receive (synchronous mode), or independent clocks (asynchronous).
The SSI driver, however, programs the SSI into synchronous mode and then
tries to program the clock registers independently. The result is that the wrong
sample size is usually generated during recording.
This patch fixes the discrepancy by restricting the sample rate and sample size
of the playback and capture streams. The SSI driver remembers which stream
is opened first. When a second stream is opened, that stream is constrained
to the same sample rate and size as the first stream.
A future version of this driver will lift the sample size restriction.
Supporting independent sample rates is more difficult, because only certain
codecs provide dual independent clocks.

Currently, even if you pass model=intel-mac-v3 as a module parameter to
snd_hda_intel, the function patch_stac922x (patch_sigmatel.c) will still
try to auto-detect the model type. This is a problem on my MacBook Pro 1st
generation, which needs intel-mac-v3, but sometimes incorrectly reports
0x00000100 as subsystem id, which causes the switch in patch_stac922x to
select intel-mac-v4.
To fix this, I added a new model called intel-mac-auto, so in case no
module parameter is passed, and an Intel Mac board is detected, the
model will be automatically detected, while no detection will be done
if the model is forced to intel-mac-v3.
This problem has been around for quite a while, and I used to fix it
by moving the case statement for 0x00000100 in patch_stac922x so that
intel-mac-v3 is chosen.
Another way to fix the problem would be to check if a module parameter
was set directly in patch_stac922x, using something like this:
if (spec->board_config == STAC_INTEL_MAC_V3 &&
!codec->bus->modelname) {
But I think it is less elegant (if you prefer that way, I can prepare a

On 32-bit architectures PAGE_ALIGN() truncates 64-bit values to the 32-bit
boundary. For example:
u64 val = PAGE_ALIGN(size);
always returns a value < 4GB even if size is greater than 4GB.
The problem resides in PAGE_MASK definition (from include/asm-x86/page.h for
example):
#define PAGE_SHIFT 12
#define PAGE_SIZE (_AC(1,UL) << PAGE_SHIFT)
#define PAGE_MASK (~(PAGE_SIZE-1))
...
#define PAGE_ALIGN(addr) (((addr)+PAGE_SIZE-1)&PAGE_MASK)
The "~" is performed on a 32-bit value, so everything in "and" with
PAGE_MASK greater than 4GB will be truncated to the 32-bit boundary.
Using the ALIGN() macro seems to be the right way, because it uses
typeof(addr) for the mask.
Also move the PAGE_ALIGN() definitions out of include/asm-*/page.h in
include/linux/mm.h.

The DAPM event callback code has many layers of indentation, taking it
over 80 columns. Refactor the code to give less indentation in order to
avoid checkpatch issues on further changes and exploding indentation.

It seems NVidia and other hardwares require the alignment for period
update timing. For satisfying this condition, align the position
adjustment for delayed wake-up to the initial bdl_pos_adj value.

kcalloc is supposed to be called with the count as its first argument and the
element size as the second.
Both arguments are size_t so does not affect correctness. This callsite is
during module_init and therefore not performance critical. Another patch will
optimize the case when the count is variable but the size is fixed.

This patch adds a new ALSA driver for the audio device found inside
many older SGI workstation (Indy, Indigo2). The hardware uses a SGI
custom chip, which feeds two codec chips, an IEC chip and a synth chip.
Currently only one of the codecs is supported. This driver already has
the same functionality as the HAL2 OSS driver and will replace it.

Fix a const pointer usage warning in the Digigram miXart soundcard driver. A
const pointer is being passed to copy_from_user() to load the firmware into.
This is okay in this case because the function has allocated the firmware
struct itself, but the const qualifier is part of the firmware struct - so the
patch casts the const away.

Standardise both in-kernel and loaded firmware to be stored as
little-endian instead of host-endian.
Signed-off-by: David Woodhouse <dwmw2@infradead.org>
The maestro3 driver is byte-swapping its firmware to be host-endian in
advance, when it doesn't seem to be necessary -- we could just use
le16_to_cpu() as we load it.
Doing that means that we need to switch the in-tree firmware to be
little-endian too.
Take the least intrusive way of doing this, which is to switch the
existing snd_m3_convert_from_le() function to convert _to_ little-endian
instead, and use it on the in-tree firmware instead of the loaded
firmware. It's a bit suboptimal but doesn't matter much right now
because we're about to remove the special cases for the in-tree version
anyway.
