Add gcd() wrapper

Detailed changelog between 1.0.22 and 1.0.22.1 releases

alsa-driver

Sound Core

- Release v1.0.22.1

- Add gcd() wrapper

- Fix pack target and improve newalsakernel target

- fix typo in $(ALSAKERNELFILE) target

- Change alsa-kernel/sound_core.c to ALSAKERNELFILE and add this dep to pack target

- Remove whole alsa-kernel tree before creating of symlinks

- introduce --with-alsakernel option for ./configure

This patch allows to choose the ALSA kernel tree. It adds support to

specify own path for the standard Linux 2.6 kernel tree.

The alsa-kmirror mode was untouched.

Also, missing isa/dt019x.c is added.

ALSA Core

- Don't define gcd() when already exists

Define compatible gcd() only when linux/gcd. doesn't exist.

CONFIG_GCD isn't defined for 2.6.31/32, so it can'be used reliablty

as the compile condition.

Reported-by: Ozan Çağlayan <ozan@pardus.org.tr>

- Fix acore/Makefile for pcm_memory.patch

- Handle __GFP_ZERO for older kernels

- Add missing EXPORT_SYMBOL() for gcd wrapper

- Add gcd() wrapper

- Add skip_spaces() wrapper

- ALSA: sound/core/pcm_timer.c: use lib/gcd.c

Make sound/core/pcm_timer.c use lib/gcd.c

PCM Midlevel

- Handle __GFP_ZERO for older kernels

- ALSA: Fix indentation in pcm_native.c

- ALSA: sound/core/pcm_timer.c: use lib/gcd.c

Make sound/core/pcm_timer.c use lib/gcd.c

- ALSA: refine rate selection in snd_interval_ratnum()

Refine the rate selection by choosing the rate

closer to the requested one in case of selecting

single frequency. Previously, the higher rate was

always selected.

Also, fix problem with the best_diff unsigned int

value wrapping (turning negative).

- ALSA: pcm - Add missing inclusion of linux/vmalloc.h

- ALSA: fix incorrect rounding direction in snd_interval_ratnum()

The direction of rounding is incorrect in the snd_interval_ratnum()

It was detected with following parameters (sb8 driver playing

8kHz stereo file):

- num is always 1000000

- requested frequency rate is from 7999 to 7999 (single frequency)

The first loop calculates div_down(num, freq->min) which is 125.

Thus, a frequency range's minimum value is 1000000 / 125 = 8000 Hz.

The second loop calculates div_up(num, freq->max) which is 126

The frequency range's maximum value is 1000000 / 126 = 7936 Hz.

The range maximum is lower than the range minimum so the function

fails due to empty result range.

- sound: pcm: add vmalloc buffer helper functions

There are now five copies of the code to allocate a PCM buffer using

vmalloc(). Add a sixth in the core so that the others can be removed.

/isa/Makefile

- Remove obsolete dt019x.c again

- introduce --with-alsakernel option for ./configure

This patch allows to choose the ALSA kernel tree. It adds support to

specify own path for the standard Linux 2.6 kernel tree.

The alsa-kmirror mode was untouched.

Also, missing isa/dt019x.c is added.

/soc/codecs/Makefile

- ASoC: Add initial WM8955 CODEC driver

The WM8955 is a low power, high quality stereo DAC with integrated

headphone and loudspeaker amplifiers, designed to reduce external

component requirements in portable digital audio applications. This is

an initial driver implementing support for the majority of the

functionality in the device, currently OUT3 is not supported.

- ASoC: Fix sorting of codecs Makefile entries

Acked-by: Liam Girdwood <lrg@slimlogic.co.uk>

- ASoC: Add DA7210 codec device support for ALSA

This original driver was created by Dialog Semiconductor,

and cleanuped by Kuninori Morimoto.

Special thanks to David Chen.

This became very simple ASoC codec driver,

and it is tested by EcoVec24 board.

Acked-by: Liam Girdwood <lrg@slimlogic.co.uk>

- ASoC: Initial WM8904 CODEC driver

The WM8904 is a high performance ultra-low power stereo CODEC

optimised for portable audio applications, with features including

a class W amplifier, FLL with free running mode, Mobile ReTune and

ground referenced headphone and line outputs.

Support for some features, most particularly the digital microphone

interface, is not yet present.

ALSA Version

- ALSA: Release v1.0.22

ARM AACI PL041 driver

- ALSA: sound/arm: Fix build failure caused by missing struct aaci definition

This patch fixes a build failure introduced by the patch

ALSA: AACI: factor common hw_params logic into aaci_pcm_hw_params [1]

by adding/moving the aaci struct to the right position.

The patch mentioned above merged common source parts into one function,

but unfortunately left out the aaci struct and consequently caused a

build failure e.g. for arm versatile_config [2]

Patch against Linus' tree.

- ALSA: AACI: switch to per-pcm locking

We can use finer-grained locking, which makes things easier when

we gain DMA support.

- ALSA: AACI: add double-rate support

- ALSA: AACI: factor common hw_params logic into aaci_pcm_hw_params

- ALSA: AACI: cleanup aaci_pcm_hw_params

Since the recording and playback paths are now the same, eliminate

the needless conditionals.

- ALSA: AACI: simplify codec rate information

There's no need for a specific rule; ALSA's generic AC'97 support

calculates the necessary rate constraint information itself, and

we can use this directly.

- ALSA: aaci - Fix a typo

Fixed a typo of the max buffer size specified for buffer allocation

changed in the commit d6797322231af98b9bb4afb175dd614cf511e5f7.

CS5535 driver

- ALSA: cs5535audio: free OLPC quirks from reliance on MGEODE_LX cpu optimization

Previously, OLPC support for the mic extensions was only enabled in the

ALSA driver if CONFIG_OLPC and CONFIG_MGEODE_LX were both set. This was

because the old geode GPIO code was written in a manner that assumed

CONFIG_MGEODE_LX. With the new cs553x-gpio driver, this is no longer the

case; as such, we can drop the requirement on CONFIG_MGEODE_LX and instead

include a requirement on GPIOLIB.

We use the generic GPIO API rather than the cs553x-specific API.

With `while (i++ < MAX_WRITE_RETRY)' i reaches MAX_WRITE_RETRY + 1 after the loop

DT019x driver

- Remove obsolete dt019x.c again

Narrow the dma and irq selection after the DOS driver.

Add ALSA configuration description as well.

- ALSA: hda - Add support for the new 27 inch IMacs

With the attached patch I am able to use the sound on a new IMac 27.

What works:

*) Internal speakers

*) Internal microphone

*) Headphone

I don't have an external mic or a SPDIF device to test the rest.

EMU8000 driver

- ALSA: sbawe: fix memory detection

Memory amount is increased before a successful write-read

sequence is done. Thus, 512 kB of onboard memory is detected

on memoryless cards like SB32.

Move the increasing of memory counter after successful read

is done.

Edirol UA-101 driver

- sound: ua101: use vmalloc buffer helper functions

Remove this duplicate of snd_pcm_alloc_vmalloc_buffer and use the

equivalent core functions instead.

HDA Codec driver

- ALSA: hda: Refactor powerdown for Realtek HDA codecs

This patch converts the alc889 Aspire-specific powerdown to a generic

one. Like the previous effort, it currently only handles Front and PCM

but can be easily extended to cover other nids. The existing hook for

alc889 Aspire-specific remains enabled. Upon further testing, I've added

its use for ALC861_AUTO as well. Following patches will enable them for

other quirks.

Tested-by: Dr. David Alan Gilbert <linux@treblig.org>

- ALSA: hda: Add powerdown for Analog Devices HDA codecs

This patch ports powerdown fixes to AD198x. Currently we only turn off

Front and HP for suspend, but this is easily extended for additional

nids.

- ALSA: hda - Use strict_strtoul()

Rewrite the codes to use strict_strtoul() instead of simple_strtoul().

- ALSA: hda - Add sanity check for storing the user-defined pin configs

Check whether the given NID is a pin widget before storing the

user-defined pin configs.

- ALSA: hda - Fix click noises at suspend/free with Realtek codecs

Call snd_hda_shutup_pins() at suspend and free for avoiding click noises.

- ALSA: hda - Add snd_hda_shutup_pins() helper function

Add a common helper function for clearing pin controls before suspend.

Use the pincfg array instead of looking through all widget tree.

- ALSA: hda - Add more hints for GPIO setup of IDT/STAC codecs

gpio_led, gpio_led_polarity and gpio_mute are added now.

- ALSA: hda - use snd_hda_jack_detect() again in patch_sigmatel.c

Use snd_hda_jack_detect() again for jack-sensing.

The triggering problem can be worked around with codec->no_trigger_sense

flag now.

- ALSA: hda - Disable tigger at pin-sensing on AD codecs

Analog Device codecs seem to have problems with the triggering of

pin-sensing although their pincaps give the trigger requirements.

Some reported that constant CPU load on HP laptops with AD codecs.

For avoiding this regression, add a flag to codec struct to notify

explicitly that the codec doesn't suppot the trigger at pin-sensing.

- ALSA: hda - Set mixer name after codec patch

Postpone the mixer name setup after the codec patch since the codec

patch may change the codec name string in itself.

- ALSA: hda - Fix NID association for capture mixers

Fix the wrong implementation of NID <-> kctl mapping for capture mixers

introduced by the ocmmit 5b0cb1d850c26893b1468b3a519433a1b7a176be.

- ALSA: hda - Fix NULL dereference with enable_beep=0 option

- ALSA: HDA: add powersaving hook for Realtek

The current Realtek code makes no specific provision for turning stuff

off. The codec chip is placed into low-power mode generically, but this

doesn't turn off any external hardware connected to it, in particular

external amplifiers.

This patch creates a hook function that is called by the codec

suspend/resume functions. It ought to disable any external hardware in a

device-specific way. I've implemented a generic ALC889 function that

sets the EAPD pin properly, and used it for the Acer Aspire 8930G which

can benefit from this feature.

On my laptop, this results in ~0.5W extra savings.

- ALSA: HDA: remove useless mixers on Aspire 8930G

This patch removes some extra mixers that do nothing on the Acer Aspire

8930G.

The CD mixer is useless because the SATA DVD/Blu-Ray drive has no analog

audio output, and the Side mixer is useless because we max out at 6ch

anyway.

- ALSA: HDA: simplify Aspire 8930G verb array

This patch just simplifies the 8930G verb array a bit. Just use the

common ALC889 EAPD verb array to make things more consistent. The file

is already huge enough already.

- ALSA: hda: Set Front Mic to input vref 50% for Lenovo 3000 Y410

BugLink: https://bugs.launchpad.net/bugs/479373

- ALSA: hda/realtek: Remove extra .capsrc_nids initialization for ALC889_INTEL

capsrc_nids can be NULL, and adc_nids should be taken as fallback.

- ALSA: hda - Fix missing capsrc_nids for ALC88x

Some model quirks missed the corresponding capsrc_nids. This resulted in

non-working capture source selection.

Fixed initialization of internal mic and added internal mic boost control

Renamed analog mic boost control to ext mic boost contol.

Name pair analog/digital seems too confusing for a normal user.

- ALSA: hda - More ALC663 fixes and support of compatible chips

1. Add more ASUS NB model.

2. Fixed alc663_m51va_setup

M51VA has Digital Mic that NID is 0x12. The record source index is

0x9 for ALC663.

So, to modify the alc663_m51va_setup function to index 0x9

and add analog Mic aupport function alc663_mode1_setup.

3. Add ASUS mode7 and mode8 modules for ALC663

HDA Intel driver

- ALSA: hda - HDMI sticky stream tag support

When we run the following commands in turn (with

CONFIG_SND_HDA_POWER_SAVE_DEFAULT=0),

speaker-test -Dhw:0,3 -c2 -twav # HDMI

speaker-test -Dhw:0,0 -c2 -twav # Analog

The second command will produce sound in the analog lineout _as well as_

HDMI sink. The root cause is, device 0 "reuses" the same stream tag that

was used by device 3, and the "intelhdmi - sticky stream id" patch leaves

the HDMI codec in a functional state. So the HDMI codec happily accepts

the audio samples which reuse its stream tag.

The proposed solution is to remember the last device each azx_dev was

assigned to, and prefer to

1) reuse the azx_dev (and hence the stream tag) the HDMI codec last used

2) or assign a never-used azx_dev for HDMI

With this patch and the above two speaker-test commands,

HDMI codec will use stream tag 8 and Analog codec will use 5.

The stream tag used by HDMI codec won't be reused by others, as long

as we don't run out of the 4 playback azx_dev's. The legacy Analog

codec will continue to use stream tag 5 because its device id is 0

(this is a bit tricky).

- ALSA: hda - Add MSI blacklist

A machine with AMD CPU with Nvidia board doesn't work with MSI.

Reported-by: Robert J. King <peritus@gurunetwork.org>

- ALSA: hda - Check class to identify Nvidia controller chips

Instead of listing all individual PCI IDs, check the matching with

the PCI class together with the vendor id for Nvidia.

This simplifies the pci id entries.

HDA generic driver

- Fix hda_intel.patch

Separate msi_whte_list to patch more robustly.

- ALSA: hda - Use strict_strtoul()

Rewrite the codes to use strict_strtoul() instead of simple_strtoul().

- ALSA: hda - Fix Oops at reloading beep devices

The recent change for supporting dynamic beep device allocation caused

a problem resulting in Oops at reloading the driver. Also, it ignores

the error from input device registration.

This patch fixes the wrong check in snd_hda_detach_beep_device(), and

returns an error when the input device registration fails properly.

- ALSA: hda - Don't cache beep controls

The beep control verbs don't need to be cached for resume.

- ALSA: hda - Fix NID association for capture mixers

Fix the wrong implementation of NID <-> kctl mapping for capture mixers

introduced by the ocmmit 5b0cb1d850c26893b1468b3a519433a1b7a176be.

spaces from strings all over the tree.

It decreases lib.a code size by 47 bytes and reuses the function tree-wide:

text data bss dec hex filename

64688 584 592 65864 10148 (TOTALS-BEFORE)

64641 584 592 65817 10119 (TOTALS-AFTER)

Also, while at it, if we see (*str && isspace(*str)), we can be sure to

remove the first condition (*str) as the second one (isspace(*str)) also

evaluates to 0 whenever *str == 0, making it redundant. In other words,

"a char equals zero is never a space".

SoC Codec WM8350

- mfd: Mask and unmask wm8350 IRQs on request and free

Bring the WM8350 IRQ API more in line with the generic IRQ API by

masking and unmasking interrupts as they are requested and freed.

This is mostly just a case of deleting the mask and unmask calls

from the individual drivers.

The RTC driver is changed to mask the periodic IRQ after requesting

it rather than only unmasking the alarm IRQ. If the periodic IRQ

fires in the period where it is reqested then there will be a

spurious notification but there should be no serious consequences

from this.

The CODEC drive is changed to explicitly disable headphone jack

detection prior to requesting the IRQs. This will avoid the IRQ

firing with no jack set up.

- mfd: Convert wm8350 IRQ handlers to irq_handler_t

This is done as simple code transformation, the semantics of the

IRQ API provided by the core are are still very different to those

of genirq (mainly with regard to masking).

- ALSA: usb-audio: relax urb data align. restriction HVR-950Q and HVR-850 only

Addressing audio quality problem.

In sound/usb/usbaudio.c, for the Hauppage HVR-950Q and HVR-850 only, change

retire_capture_urb to allow transfers on audio sub-slot boundaries rather

than audio slots boundaries.

With these devices the left and right channel samples can be split between

two different urbs. Throwing away extra channel samples causes a sound

quality problem for stereo streams as the left and right channels are

swapped repeatedly, perhaps many times per second.

Urbs unaligned on sub-slot boundaries are still truncated to the next

lowest stride (audio slot) to retain synchronization on samples even

though left/right channel synchronization may be lost in this case.

Detect the quirk using a case statement in snd_usb_audio_probe.
