ALSA Core

- Fix bint check version check

It seems that the bint stuff is not a part of 3.2 kernel as it's

pulled by Linus only a few days ago, so increment version check

to 3.3.0:

commit 69116f279a9eaf4c540934269342d9149538fc79

Author: Rusty Russell <rusty@rustcorp.com.au>

Date: Fri Jan 13 09:32:17 2012 +1030

module_param: avoid bool abuse, add bint for special cases.

- Add a build fix for older kernels due to info() macro

Since some old kernels define info() macro, the build gets broken.

Simply undefine such a stupid macro.

- Release check: Supported kernel versions update, changes for recent 3.2 kernel

- Add module_driver() and module_usb_driver() macros and bint module param check

- Add the build-stub for compress-offload

Enabled only from 3.0, to be sure.

- Add acore/ctljack.c build stub

- Add a wrapper for module_platform_driver() for older kernels

- Add a wrapper of to_delayed_work() for older kernels

- RHEL 6.1 compilation fix

RHEL 6.1 (2.6.32-132.*) kernels already have hex_to_bin() function.

Tune check in the alsa-driver/include/adriver.h

Tested on Scientific Linux 6.1 (RHEL 6.1 clone), kernels:

2.6.32-131.0.15.el6.x86_64 (original, from DVD installation)

2.6.32-131.17.1.el6.x86_64 (last security update)

- Add the build of acore/memory.c with older kernel

- Define the dumy __printf() when not defined

- More fixes for pm_qos changes in 3.2-rc1

- Add PMSG_IS_AUTO() check from <linux/pm.h> for older kernels

- Fix build error due to redefinition of request_irq() for older kernels

- Add a workaround for removal of IRQF_DISABLED

- Add missing export of snd_hidden_ksize()

Also fix the ifdef of krealloc() wrapper for some corner cases.

- Add missing ksize() and krealloc() wrappers for memory debugging

Otherwise krealloc() will spew many errors.

- Fix tracepoint handling with SLE11-SP0 kernel

SLE11-SP0 kernel contains half-baked tracepoint support that breaks the

build. Put a workaround.

- More workaround for older tracepoint

- Fix tracepoint.h wrapper

- Fix compile warnings with older kernels

- Add a wrapper for trace/define_trace.h

Also get rid of the old hack for trace/events/asoc.h.

- Add <linux/tracepoint.h> wrapper

- Regenerate info.patch for upstream changes in info.c

- Fix build-errors of soc-core due to new trace points

Ugly hacks again.

- Fix cancel_work_sync() wrapper for older kernels

It's hard to find the matching one...

- Define cancel_work_sync for old 2.6.x kernels

- Avoid patching for pci/ad1889 driver

It's just missing pci-ids, so let's define them in pci_ids_compat.h.

- Add PCI device ID for Creative Titanium HD to pci_ids_compat.h.

- Fix snd_printk() helper build for older kernels without %pV support

- Add krealloc() wrapper for 2.6 kernels

2.4 kernels still have no wrapper, but it's used only in soc-core...

- Add missing PCI ID for DIGIGRAM

- Add linux/bitrev.h wrapper for older kernels

- Add usleep_range() wrapper for older kernels

- add check for vzalloc() to configure (Fedora 14 kernel issue)

- Add a wrapper of async API for older kernels

- Fix build with the recent ASoC updates

- Regenerated soc-core.patch

- Always use the dummy trace/events/asoc.h

- ALSA: Don't prompt for CONFIG_SND_COMPRESS_OFFLOAD

CONFIG_SND_COMPRESS_OFFLOAD is an item to be selected by the dirver

just like CONFIG_SND_PCM, and no need to prompt for explicit

selection.

- switch procfs to umode_t use

both proc_dir_entry ->mode and populating functions

- drop "select GCD" from three Kconfig files

There is no Kconfig symbol named GCD. The three select statements for

that symbol are nops. Drop these.

- Merge all missing things from upstream.

- ALSA: hda - Add missing inclusion of linux/export.h

This is needed newly since 3.2...

- ALSA: Introduce common helper functions for jack-detection control

Now move the helper function for creating and reporting the jack-detection

to the common place. The driver that needs this functionality should

select CONFIG_SND_KCTL_JACK kconfig.

- ALSA: export compress headers

Export compress_offload.h and compress_params.h for userland to use

- ALSA: core: add makefile and kconfig file for compress

- ALSA: core: add support for compress_offload

This patch adds core.c, the file which implements the ioctls and

registers the devices

- ALSA: core: add API header and driver header files

This patch adds the header files for ioctl definitions and header file for

driver APIs for lower level device drivers to use

- ALSA: core: add compress parameter definations

The patch adds the various definations used to define the encoder

and decoder parameters

Reviewed-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

- ALSA: core: add support for compressed devices

Use the minor numbers 2 and 3 for audio compressed offload devices.

Also add support for these devices in core

Reviewed-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

- include: replace linux/module.h with "struct module" wherever possible

The <linux/module.h> pretty much brings in the kitchen sink along

with it, so it should be avoided wherever reasonably possible in

terms of being included from other commonly used <linux/something.h>

files, as it results in a measureable increase on compile times.

The worst culprit was probably device.h since it is used everywhere.

This file also had an implicit dependency/usage of mutex.h which was

masked by module.h, and is also fixed here at the same time.

There are over a dozen other headers that simply declare the

struct instead of pulling in the whole file, so follow their lead

and simply make it a few more.

Most of the implicit dependencies on module.h being present by

these headers pulling it in have been now weeded out, so we can

finally make this change with hopefully minimal breakage.

- sound: Add export.h for THIS_MODULE/EXPORT_SYMBOL where needed

These aren't modules, but they do make use of these macros, so

they will need export.h to get that definition. Previously,

they got it via the implicit module.h inclusion.

- sound: add moduleparam.h to users of module_param/MODULE_PARM_DESC

These files were getting access to these two via the implicit

presence of moduleparam.h everywhere. But that is being fixed, so

get these guys what they need in advance.

- treewide: use __printf not __attribute__((format(printf,...)))

Standardize the style for compiler based printf format verification.

Standardized the location of __printf too.

Done via script and a little typing.

$ grep -rPl --include=*.[ch] -w "__attribute__" * | \

grep -vP "^(tools|scripts|include/linux/compiler-gcc.h)" | \

xargs perl -n -i -e 'local $/; while (<>) { s/\b__attribute__\s*\(\s*\(\s*format\s*\(\s*printf\s*,\s*(.+)\s*,\s*(.+)\s*\)\s*\)\s*\)/__printf($1, $2)/g ; print; }'

[akpm@linux-foundation.org: revert arch bits]

- ALSA: control: add support for ENUMERATED user space controls

Handling of user control elements was implemented for all types except

ENUMERATED. This type will be needed for the device-specific mixers of

upcoming FireWire drivers.

- get rid of create_proc_entry() abuses - proc_mkdir() is there for purpose

- ALSA: Use %pV for snd_printk()

Clean up snd_printk() helper using the %pV prefix for recursive printks.

This also automagically fixes an Oops with RO/NX-enabled modules.

Tested-by: Maarten Lankhorst <m.b.lankhorst@gmail.com>

- ALSA: core: remove unused variables.

Drop a few variables that are never read.

- ALSA: core - Don't use "default' for default

The card-id parser assigns the string "default" when no appropriate word

is found in the card name. But this string may confuse the alsa-lib, so

better to avoid. Use "Default" now instead.

- ALSA: Fix yet another race in disconnection

This patch fixes a race between snd_card_file_remove() and

snd_card_disconnect(). When the card is added to shutdown_files list

in snd_card_disconnect(), but it's freed in snd_card_file_remove() at

the same time, the shutdown_files list gets corrupted. The list member

must be freed in snd_card_file_remove() as well.

Reported-and-tested-by: Russ Dill <russ.dill@gmail.com>

- ALSA: core: sparse cleanups

Change the core code where sparse complains. In most cases, this means

just adding annotations to confirm that we indeed want to do the dirty

things we're doing.

SoC PXA2xx Core

see Detailed SoC changes v1.0.24 v1.0.25

Control Midlevel

- Regenerated patches for new inclusions in 3.2-rc1

- Merge all missing things from upstream.

- ALSA: control: remove compilation warning on 32-bit

This was introduced by 'ALSA: control: add support for ENUMERATED user

space controls' which adds a u64 variable that gets cast to a pointer:

sound/core/control.c: In function 'snd_ctl_elem_init_enum_names':

sound/core/control.c:1089: warning: cast to pointer from integer of different size

Cast to uintptr_t before casting to pointer to avoid the warning.

[cl: replace long with uintptr_t]

- sound: Add module.h to the previously silent sound users

Lots of sound drivers were getting module.h via the implicit presence

of it in <linux/device.h> but we are going to clean that up. So

fix up those users now.

- ALSA: control: add support for ENUMERATED user space controls

Handling of user control elements was implemented for all types except

ENUMERATED. This type will be needed for the device-specific mixers of

upcoming FireWire drivers.

- ALSA: core: release the constraint check for replace ops

Suppose the ALSA card already has a number of MAX_USER_CONTROLS controls, and

the user wants to replace one, it should not fail at this condition check.

- ALSA: core: trivial code style fix

remove trailing tab on the line.

- ALSA: core: remove unused variables.

Drop a few variables that are never read.

- ALSA: Add snd_ctl_replace() to dynamically replace a control

Add a function to dynamically replace a given control. If the

control does not already exist, a third parameter is used to determine

whether to actually add that control. This is useful in cases where

downloadable firmware at runtime can add or replace existing controls.

A separate patch needs to be made to allow ALSA Mixer to render the

replaced controls on the fly.

- ALSA: Add snd_ctl_activate_id()

Added a new API function snd_ctl_activate_id() for activate / inactivate

the control element dynamically.

- ALSA: control: clean up snd_ctl_hole_check()

The return value of snd_ctl_hole_check() is used only to detect whether

to continue the loop in snd_ctl_find_hole() or not, so we can simplify

the code by changing this return type to a boolean. Also rename this

function to better show what it actually does.

- ALSA: control: fix numid conflict check for new controls

The purpose of the snd_ctl_hole_check() function is to find conflicts

between the numerical IDs of the new control and those of any existing

controls. However, it would fail to detect an existing control whose

count is smaller than the new control's count and whose interval of IDs

is entirely contained in the interval of the new control's IDs.

To fix this, use the correct formula to detect overlapping intervals,

which happens to simplify the condition.

This problem was not encountered so far because ALSA does not yet allow

drivers to allocate specific control IDs.

- ALSA: pcm: add snd_pcm_hw_rule_noresample()

Add a helper function to allow drivers to disable hardware resampling

- ALSA: pcm - fix race condition in wait_for_avail()

wait_for_avail() in pcm_lib.c has a race in it (observed in practice by an

Intel validation group).

The function is supposed to return once space in the buffer has become

available, or if some timeout happens. The entity that creates space (irq

handler of sound driver and some such) will do a wake up on a waitqueue

that this function registers for.

However there are two races in the existing code

1) If space became available between the caller noticing there was no

space and this function actually sleeping, the wakeup is missed and the

timeout condition will happen instead

2) If a wakeup happened but not sufficient space became available, the

code will loop again and wait for more space. However, if the second

wake comes in prior to hitting the schedule_timeout_interruptible(), it

will be missed, and potentially you'll wait out until the timeout

happens.

The fix consists of using more careful setting of the current state (so

that if a wakeup happens in the main loop window, the schedule_timeout()

falls through) and by checking for available space prior to going into the

schedule_timeout() loop, but after being on the waitqueue and having the

state set to interruptible.

- ALSA: sound, core, pcm_lib: fix xrun_log

The xrun_log function was augmented with the in_interrupt parameter whereas the

empty macro definition used when xrun logging is disabled was not.

Add a third parameter to the empty macro definition so as to not cause compiler

errors when xrun logging (CONFIG_SND_PCM_XRUN_DEBUG) is disabled.

- ALSA: sound, core, pcm_lib: xrun_log: log also in_interrupt

When debugging pcm drivers I found the "period" or "hw" prefix printed

by either XRUN_DEBUG_PERIODUPDATE or XRUN_DEBUG_PERIODUPDATE events,

respectively to be very useful is observing the interplay between

interrupt-context updates and syscall-context updates.

Similarly, when debugging overruns with XRUN_DEBUG_LOG it is useful to

see the context of the last 10 positions.

Add an in_interrupt member to hwptr_log_entry which stores the value of

the in_interrupt parameter of snd_pcm_update_hw_ptr0 when the log entry

is created. Print a "[Q]" prefix when dumping the log entries if

in_interrupt was true.

- ALSA: pcm: fix infinite loop in snd_pcm_update_hw_ptr0()

When period interrupts are disabled, snd_pcm_update_hw_ptr0() compares

the current time against the time estimated for the current hardware

pointer to detect xruns. The somewhat fuzzy threshold in the while loop

makes it possible that hdelta becomes negative; the comparison being

done with unsigned types then makes the loop go through the entire 263

negative range, and, depending on the value, never reach an unsigned

value that is small enough to stop the loop. Doing this with interrupts

disabled results in the machine locking up.

To prevent this, ensure that the loop condition uses signed types for

both operands so that the comparison is correctly done.

Many thanks to Kelly Anderson for debugging this.

- ALSA: vmalloc buffers should use normal mmap

It's a big no-no to use pgprot_noncached() when mmap'ing such buffers

AD1816A driver

- ALSA: mpu401: clean up interrupt specification

The semantics of snd_mpu401_uart_new()'s interrupt parameters are

somewhat counterintuitive: To prevent the function from allocating its

own interrupt, either the irq number must be invalid, or the irq_flags

parameter must be zero. At the same time, the irq parameter being

invalid specifies that the mpu401 code has to work without an interrupt

allocated by the caller. This implies that, if there is an interrupt

and it is allocated by the caller, the irq parameter must be set to

a valid-looking number which then isn't actually used.

With the removal of IRQF_DISABLED, zero becomes a valid irq_flags value,

which forces us to handle the parameters differently.

This patch introduces a new flag MPU401_INFO_IRQ_HOOK for when the

device interrupt is handled by the caller, and makes the allocation of

the interrupt to depend only on the irq parameter. As suggested by

Takashi, the irq_flags parameter was dropped because, when used, it had

the constant value IRQF_DISABLED.

This is mostly a static checker fix more than anything else. We're

The call tree is:

We never actually do fill str[] buffer all the way to 64 characters.

The longest string is:

sprintf(str, "%s Playback Switch", ptr->name);

ptr->name is a 32 character buffer so 32 plus 16 characters for

" Playback Switch" still puts us over the 44 limit from "id.name".

Since commit [e58aa3d2: genirq: Run irq handlers with interrupts disabled],

We run all interrupt handlers with interrupts disabled

and we even check and yell when an interrupt handler

returns with interrupts enabled (see commit [b738a50a:

genirq: Warn when handler enables interrupts]).

So now this flag is a NOOP and can be removed.

- ASoC: PXA: Fix oops in __pxa2xx_pcm_prepare

pxa2xx_pcm_hw_free frees dma channel and sets prtd->dma_ch to -1,

but does not set prtd->params to NULL, so if pxa2xx_pcm_hw_params will

be called immediately, it leaves prtd->dma_ch initialized with -1,

and it results in oops in __pxa2xx_pcm_prepare. This bug is triggered

via SDL.

This patch adds check for prtd->dma_ch to __pxa2xx_pcm_prepare and

cleans prtd->params, so now it works properly.

ATIIXP driver

AZT2320 driver

- ALSA: mpu401: clean up interrupt specification

The semantics of snd_mpu401_uart_new()'s interrupt parameters are

somewhat counterintuitive: To prevent the function from allocating its

own interrupt, either the irq number must be invalid, or the irq_flags

parameter must be zero. At the same time, the irq parameter being

invalid specifies that the mpu401 code has to work without an interrupt

allocated by the caller. This implies that, if there is an interrupt

and it is allocated by the caller, the irq parameter must be set to

a valid-looking number which then isn't actually used.

With the removal of IRQF_DISABLED, zero becomes a valid irq_flags value,

which forces us to handle the parameters differently.

This patch introduces a new flag MPU401_INFO_IRQ_HOOK for when the

device interrupt is handled by the caller, and makes the allocation of

the interrupt to depend only on the irq parameter. As suggested by

Takashi, the irq_flags parameter was dropped because, when used, it had

the constant value IRQF_DISABLED.

AZT3328 driver

- ALSA: azt3328 - adjust error handling code to include debugging code

snd_azf3328_dbgcallenter is called at the very beginning of the function,

so it could be useful to call snd_azf3328_dbgcallleave at all exit points.

- ALSA: azt3328: add custom AC97 semi-emulation use standard ALSA AC97 layer

Make use of the very flexible ALSA ac97 layer (hooks for custom I/O!)

on this weird AC97 copycat hardware,

via semi-extended I/O translation/emulation.

Some 5kB binary/loaded size saved (well... additional huge AC97 module

penalty not factored in, of course ;-P).

Given that the driver previously had 20kB that's not bad,

but the much more important thing is to have AC97 layer stress-tested

with a thoroughly weird AC97 copycat (or, simply put, if it were not for

this AC97 test aspect, this effort would merely have been a nut job ;).

The name argument of request_irq() appears in /proc/interrupts, and

there, so let's replace all entries with KBUILD_MODNAME.

- ALSA: Use KBUILD_MODNAME for pci_driver.name entries

The convention for pci_driver.name entry in kernel drivers seem to be

the module name or equivalent ones. But, so far, almost all PCI sound

confusing when appearing as a file name.

This patch converts the all pci_driver.name entries in sound/pci/* to

use KBUILD_MODNAME for more unified appearance.

CMI8330 driver

- ALSA: mpu401: clean up interrupt specification

The semantics of snd_mpu401_uart_new()'s interrupt parameters are

somewhat counterintuitive: To prevent the function from allocating its

own interrupt, either the irq number must be invalid, or the irq_flags

parameter must be zero. At the same time, the irq parameter being

invalid specifies that the mpu401 code has to work without an interrupt

allocated by the caller. This implies that, if there is an interrupt

and it is allocated by the caller, the irq parameter must be set to

a valid-looking number which then isn't actually used.

With the removal of IRQF_DISABLED, zero becomes a valid irq_flags value,

which forces us to handle the parameters differently.

This patch introduces a new flag MPU401_INFO_IRQ_HOOK for when the

device interrupt is handled by the caller, and makes the allocation of

the interrupt to depend only on the irq parameter. As suggested by

Takashi, the irq_flags parameter was dropped because, when used, it had

the constant value IRQF_DISABLED.

- ALSA: virtuoso: Xonar DS: fix polarity of front output

- ALSA: virtuoso: add S/PDIF input support for all Xonars

All Xonar cards support S/PDIF input, but the cards without optical or

coaxial plugs have only undocumented pin connectors. Support for the

ST/STX was already added in a previous patch; this adds support for the

D1/DX (JP2), DG (J5), DS (J5), and HDAV Slim (J12).

Many thanks to Zoltan Miklos for testing the DS and DX.

- ALSA: virtuoso: fix Essence ST(X) S/PDIF input

On the Xonar Essence ST/STX, the connector J14 has been confirmed to be

a digital input, so enable it in the driver.

- ALSA: virtuoso: fix silent analog output on Xonar Essence ST Deluxe

Commit dd203fa97bd5 (ALSA: virtuoso: remove non-working controls on

Essence ST Deluxe) made it impossible to adjust the volume after the

driver initialized it to muted.

Ensure that those DACs that can be accessed with I2C are initialized

to the same volume that is the reset default of the DAC without I2C.

- ALSA: firewire-speakers, oxygen, ua101: allow > 10 s periods

Since commit f2b3614cefb6 (Don't check DMA time-out too shortly),

drivers need no longer restrict their PCM period length to be shorter

than 10 seconds.

- ALSA: oxygen: fix output routing on Xonar DG

This card uses separate I2S outputs for the front speakers and

headphones, and reverses the order of the three speaker outputs.

To work around this, add a model-specific callback to adjust the

controller's playback routing.

Creative Sound Blaster X-Fi (20K1/20K2)

- ALSA: ctxf: Use kcalloc instead of kzalloc to allocate array

The advantage of kcalloc is, that will prevent integer overflows which could

result from the multiplication of number of elements and size and it is also

a bit nicer to read.

The semantic patch that makes this change is available

in https://lkml.org/lkml/2011/11/25/107

- ALSA: ctxfi: Bump playback substreams to 256

There are references in the code to 256 sources, so I tested it with 256 aplays,

of which the first and last with real data and the rest playing /dev/zero .

Also increase amount of page tables, so the default aplay size works.

- ALSA: ctxfi: Change PLL initialization code

This is a reworked patch from Creative to change the PLL code to address

unreliable 44100Hz initialization.

- ALSA: ctxfi: Implement a combined capabilities query method to replace multiple have_x query methods.

Initialise model-specific DAC and ADC parts.

Add controls for output and mic source selection.

Rename some mixer controls according to ControlNames.txt.

Remove Playback switches for Line-in and IEC958-in - these

were controlling the input mute/unmute which affected

capture too. Use the capture switches to control the

input mute/unmute instead - it's less confusing.

Initialise the WM8775 to invert the left-right clock

- ALSA: lola - Implement polling_mode like hd-audio

Also protect the call of lola_update_rirb() with spinlock.

- ALSA: lola - Rename to Digital SRC Capture Switch

Renamed to Digial SRC Capture Switch for more correct representation.

Also fixed analog volume control on Lola161611 and lola881.

- ALSA: lola - Add sync in loop implementation

For assuring the synchronized state with the pause operation,

loop over the all linked streams and waits until all get ready

in a loop.

- ALSA: lola - Add SRC refcounting

Also, fixed the possible stall after PCM pause operations.

- ALSA: lola - Allow granularity changes

Add some sanity checks.

Change PCM parameters appropriately per granularity.

- ALSA: lola - Use SG-buffer

Completely switch to SG-buffer now, as it's working stably.

- ALSA: lola - Add Lola-specific module options

Added granularity and sample_rate_min module options.

The former controls the h/w access granularity. As default, it's set

to the max value 32.

The latter controls the minimum sample rate in Hz, as default 16000.

- ALSA: lola - Fix PCM stalls

- ALSA: lola - Use a single BDL

Use a single BDL for both buffers instead of allocating for each.

Also a few tune-up to avoid the stream stalls in the PCM code and

the prelimianry work for SG-buffer support are added, too.

- ALSA: lola - Suppress the debug print

Use snd_printdd() for less important debug messages.

- ALSA: lola - Changes in proc file

The codec proc file becomes a read only that shows the codec widgets

in a text form. A new proc file, codec_rw, is introduced instead for

accessing the Lola verb directly by reading and writing to it.

Also, regs proc file shows the contents of DSD, too.

- ALSA: lola - Make SRC helper global

Make lola_sample_rate_convert() global so that it can be accessed from

other files.

- ALSA: Add the driver for Digigram Lola PCI-e boards

Added a new driver for supporting Digigram Lola PCI-e boards.

Lola has a similar h/w design like HD-audio but with extended verbs.

Thus the driver is written similarly like HD-audio driver in the bus

part. The codec part is rather written in a fixed way specific to the

Lola board because of the verb incompatibility.

The driver provides basic PCM, supporting multi-streams and mixing.

- ALSA: hda: remove unused quirk for inverted mute led

Commit b99a776d0b17ae0f3a54e86009887a00ac4889d0 removed all effects of

the STAC92HD83* model quirk "hp". However, it left the model selection

and documentation behind, confusing users with inverted mute

leds. Completely remove this quirk and its documentation.

- ASoC: Remove references to corgi and spitz from machine driver document

They're not currently actively worked on, the hardware being rather

- ALSA: hda - Update URLs in document

Some stuff was moved from kernel.org to other places.

- ALSA: hda/realtek - Remove all ALC262-quirk codes

- ALSA: hda - fix internal mic on Dell Vostro 3500 laptop

Fix the not working internal mic on Dell Vostro 3500 laptop by introducing the

new model dell-vostro-3500.

- ALSA: hda - Fix typo

- ALSA: hda - Add documentation for codec specific mixer controls of Analog codecs

* Channel Mode

This is an enum control to change the surround-channel setup,

appears only when the surround channels are available.

It gives the number of channels to be used, "2ch", "4ch" abd "6ch".

According to the configuration, this also controls the

jack-retasking of multi-I/O jacks.

* Independent HP

When this enum control is enabled, the headphone output is routed

from an individual stream (the third PCM such as hw:0,2) instead of

the primary stream.

- ALSA: hda - Allow patching with any vendor/subsystem ids

In the ugly real world, there area really broken devices that don't set

codec SSID correctly. In such a case, the ID can be random, thus the

patching won't work reliably.

For applying the patch forcibly to such a device, the driver will skip

the vendor and/or subsystem ID checks when zero or a negative number is

given in [codec] section.

- 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.

- ALSA: hda - Remove the rest of ALC662 quirks

The rest of ALC662 quirks are only for desktops, and they should work

with the auto-parser.

- ALSA: hda - Remove ALC662 ASUS eeepc-ep20 model quirk

Since the recent fixes, this device works with the auto-parser well.

Let's kill it.

- ALSA: hda - Rewrite Lenovo X200 quirk with pincfg-fix using auto-parser

Introduce the pincfg table to patch_conexant.c for fixing up the extra

pin-configuration for auto-parser. As an example, Lenovo X200 model is

replaced with this new mechanism. (This also fixes the wrong mixer

elements for docking-station I/O in the previous model quirk

automagically.)

- ALSA: hda - Remove ALC662 ASUS M51VA, G71V, H13 and G50V model quirks

These models work now with the BIOS auto-parser, so let's drop them.

- ALSA: hda - Rewrite ALC269 laptop-amic,dmic,&co quirks with fixups

Similarly like ALC662 asus-mode* models, rewrite the laptop-amic and

dmic models with the static pin-config tables.

Now we can get rid of all alc269_quirks.c.

- ALSA: hda - Remove all ALC861 and ALC861-VD quirks

Let's remove the rest of ALC861 and ALC861-VD quirks.

If any breakage is found, it can be fixed easily via the pin-config

table update.

- ALSA: hda - Remove ALC662 model=levono-101e model quirk

- ALSA: hda - Remove ALC662 eeepc-p701 and ecs models

specific COEF and pin configurations. Removed the model entries

from alc269_quirks.c.

- ALSA: hda - Remove acer, acer-aspire and acer-dmic models for ALC268

Moved some code to alc269_quirks.c for dependency, too.

- ALSA: hda - Remove ALC269 model=futjisu and Acer

Both are supported by the auto-parser.

- ALSA: hda - Remove dell, dell-zm1 and samsung-nc10 models for ALC272

The auto-parser works for these models.

- ALSA: hda - Remove ALC260 HP model quirks

ALC260 HP models work with the BIOS auto-parser. Let's cut them off.

Also move alc260_hp_master_*() to alc262_quirks.c as these are still

- ALSA: hda - Remove ALC262 HP and sony-assamd quirks

HP and sony-assamd models work with the BIOS auto-parser nowadays,

so let's reduce the unnecessary code.

- ALSA: hda - Add tracepoint for unsolicited events

- ALSA: hda - Add documentation for tracepoints

- ALSA: hda: option to enable arbitrary buffer/period sizes

Add new parameter to disable rounding of buffer/period sizes to

multiples of 128 bytes. This is more efficient in terms of memory

access but isn't required by the HDA spec and prevents users from

specifying exact period/buffer sizes. For example for 44.1kHz, a

period size set to 20ms will be rounded to 19.59ms.

Tested and enabled on Intel HDA controllers. Option is disabled by

default for other controllers.

- ALSA: isight: adjust for new queueing API

Since commit 13882a82ee16 (optimize iso queueing by setting

wake only after the last packet), drivers are required to call

fw_iso_context_queue_flush() after queueing a batch of packets.

The missing call would have an effect only if the controller

queue underruns, but then the DMA would stop completely.

- ALSA: isight: fix locking

Lockdep complains about conflicts between isight->mutex,

ALSA's register_mutex, mm->mmap_sem, and pcm->open_mutex.

This can be fixed by moving the calls to isight_pcm_abort(),

snd_card_disconnect(), and fw_iso_resources_update() out of

isight->mutex. These functions are designed to be called

asynchronously; the mutex needs to protect only the device

streaming state modified by isight_start/stop_streaming().

- ALSA: isight: fix hang when unplugging a running device

When aborting a PCM stream, the xrun is signaled only if the stream is

running. When disconnecting a PCM stream, calling snd_card_disconnect()

prevent the xrun from being noticed by user space.

To prevent this, move the snd_card_disconnect() call after the xrun.

- firewire: optimize iso queueing by setting wake only after the last packet

When queueing iso packets, the run time is dominated by the two

MMIO accesses that set the DMA context's wake bit. Because most

drivers submit packets in batches, we can save much time by

removing all but the last wakeup.

The internal kernel API is changed to require a call to

fw_iso_context_queue_flush() after a batch of queued packets.

The user space API does not change, so one call to

FW_CDEV_IOC_QUEUE_ISO must specify multiple packets to take

advantage of this optimization.

In my measurements, this patch reduces the time needed to queue

fifty skip packets from userspace to one sixth on a 2.5 GHz CPU,

or to one third at 800 MHz.

- firewire: octlet AT payloads can be stack-allocated

We do not need slab allocations anymore in order to satisfy

streaming DMA mapping constraints, thanks to commit da28947e7e36

"firewire: ohci: avoid separate DMA mapping for small AT payloads".

(Besides, the slab-allocated buffers that firewire-core, firewire-sbp2,

and firedtv used to provide for 8-byte write and lock requests were

still not fully portable since they crossed cacheline boundaries or

shared a cacheline with unrelated CPU-accessed data. snd-firewire-lib

got this aspect right by using an extra kmalloc/ kfree just for the

8-byte transaction buffer.)

This change replaces kmalloc'ed lock transaction scratch buffers in

firewire-core, firedtv, and snd-firewire-lib by local stack allocations.

Perhaps the most notable result of the change is simpler locking because

there is no need to serialize usages of preallocated per-device buffers

anymore. Also, allocations and deallocations are simpler.

- ALSA: firewire-speakers: fix hang when unplugging a running device

When aborting a PCM stream, the xrun is signaled only if the stream is

running. When disconnecting a PCM stream, calling snd_card_disconnect()

too early would change the stream into a non-running state and thus

prevent the xrun from being noticed by user space.

To prevent this, move the snd_card_disconnect() call after the xrun.

- ALSA: firewire-lib, firewire-speakers: handle packet queueing errors

Add an AMDTP stream error state that occurs when we fail to queue

another packet. In this case, the stream is stopped, and the error can

be reported when the application tries to restart the PCM stream.

- ALSA: firewire-lib: allocate DMA buffer separately

For correct cache coherency on some architectures, DMA buffers must be

allocated in a different cache line than data that is concurrently used

by the CPU.

- ALSA: firewire-lib: use no-info SYT for packets without SYT sample

In non-blocking mode, the SYT_INTERVAL is larger than the number of

audio frames in each packet, so there are packets that do not contain

any frame to which the SYT could be applied. For these packets, the

SYT must not be the timestamp of the next valid SYT frame, but the

special no-info SYT value.

This fixes broken playback on the FireWave at 44.1 kHz.

HR timer driver

- ALSA: hrtimer: remove superfluous tasklet invocation

Commit bb758e9637e5ddc removed snd_hrtimer_callback() from the hardware

interrupt handler, thus moving it into a tasklet, but did not tell the

ALSA timer framework about this, so the timer handling would now be done

in the ALSA timer tasklet scheduled from another tasklet.

To fix this, add the flag to tell the ALSA timer framework that the

timer handler is already being invoked in a tasklet.

- ALSA: hrtimer: handle delayed timer interrupts

If a timer interrupt was delayed too much, hrtimer_forward_now() will

forward the timer expiry more than once. When this happens, the

additional number of elapsed ALSA timer ticks must be passed to

snd_timer_interrupt() to prevent the ALSA timer from falling behind.

This mostly fixes MIDI slowdown problems on highly-loaded systems with

badly behaved interrupt handlers.

ALSA: intel8x0: improve virtual environment detection

- Regenerate patches to fix fuzz for 3.2-rc1 changes

- Fix build of intel8x0 with older kernels

Just add a check of X86_FEATURE_HYPERVISOR (added since 2.6.29)

- module_param: avoid bool abuse, add bint for special cases.

For historical reasons, we allow module_param(bool) to take an int (or

an unsigned int). That's going away.

A few drivers really want an int: they set it to -1 and a parameter

will set it to 0 or 1. This sucks: reading them from sysfs will give

'Y' for both -1 and 1, but if we change it to an int, then the users

might be broken (if they did "param" instead of "param=1").

Use a new 'bint' parser for them.

(ntfs has a different problem: it needs an int for debug_msgs because

it's also exposed via sysctl.)

- ALSA: intel8x0: improve virtual environment detection

- ALSA: intel8x0: Improve performance in virtual environment

v3: detection code is x86 and KVM specific, hide it under ifdef

v2: add detection for virtual environments (KVM and Parallels)

This patch is intended to improve performance in virtualized environments

like Parallels Desktop or KVM/VirtualBox/QEMU (virtual ICH/AC97 audio).

I/O access is very time-expensive operation in virtual world: VCPU

can be rescheduled and in the worst case we get more than 10ms delay on

each I/O access.

In the virtual environment loop exit rule

(old_civ == current_civ && old_picb == current_picb) is never satisfied,

because old_picb is never the same as current_picb due to delay inspired

by reading current_civ. As a result loop ended by timeout and we get 10x

more I/O operations.

second):

- ALSA: intel8x0m: add 'm' as "suffix" to static functions

Adding an 'm' will distinguish them from identical names in intel8x0.c.

- ALSA: intel8x0m: wait a bit before warm reset check

At every resume a laptop I use prints this message (at KERN_ERR level):

ALSA sound/pci/intel8x0m.c:904: AC'97 warm reset still in progress? [0x2]

The thing to note here is that 0x2 corresponds to ICH_AC97COLD. Ie, what

seems to be happening is that the register involved indicated a warm

reset for some time (as the ICH_AC97WARM bit was set) but by the time

the warning is printed, and that same register is checked again, that

bit is already cleared and only the ICH_AC97COLD bit is still set.

It turns out a warm reset needs some time to settle, but it is currently

checked right away. The test therefore fails the first time it is done

and schedule_timeout_uninterruptible() will be called. Once we return

from that jiffies is already (far) past end_time on this laptop, so we

exit the loop, print a warning, and exit the function while the warm

reset actually succeeded.

A way to fix this is to call usleep_range() after writing to the

register involved. A handful of tests suggest 500 usecs is a safe value.

(This might punish the "finish cold reset" case, but on this laptop such

a cold reset apparently never happens, so I can't say for sure.)

While we're at it drop the extra single tick from end_time, as it looks

rather silly.

So now this flag is a NOOP and can be removed.

- ALSA: mpu401: clean up interrupt specification

The semantics of snd_mpu401_uart_new()'s interrupt parameters are

somewhat counterintuitive: To prevent the function from allocating its

own interrupt, either the irq number must be invalid, or the irq_flags

parameter must be zero. At the same time, the irq parameter being

invalid specifies that the mpu401 code has to work without an interrupt

allocated by the caller. This implies that, if there is an interrupt

and it is allocated by the caller, the irq parameter must be set to

a valid-looking number which then isn't actually used.

With the removal of IRQF_DISABLED, zero becomes a valid irq_flags value,

which forces us to handle the parameters differently.

This patch introduces a new flag MPU401_INFO_IRQ_HOOK for when the

device interrupt is handled by the caller, and makes the allocation of

the interrupt to depend only on the irq parameter. As suggested by

Takashi, the irq_flags parameter was dropped because, when used, it had

the constant value IRQF_DISABLED.

In case of a second HDSPM card, its name would be Default_1. This is

cumbersome, because the order of the cards isn't stable across reboots.

To help userspace tools referring to the correct card, this commit

provides a unique id for each card:

2 [HDSPMxf1cd85 ]: HDSPM - RME RayDAT_f1cd85

RME RayDAT S/N 0xf1cd85 at 0xf7300000, irq 18

In this example, userspace (configuration files) would then use

- ALSA: hdspm - potential info leak in snd_hdspm_hwdep_ioctl()

Smatch has a new check for Rosenberg type information leaks where

structs are copied to the user with uninitialized stack data in them.

The status struct has a hole in it, and on some paths not all the

members were initialized.

struct hdspm_status {

unsigned char card_type; /* 0 1 */

/* XXX 3 bytes hole, try to pack */

enum hdspm_syncsource autosync_source; /* 4 4 */

long long unsigned int card_clock; /* 8 8 */

The hdspm_version struct had holes in it as well.

struct hdspm_version {

unsigned char card_type; /* 0 1 */

char cardname[20]; /* 1 20 */

/* XXX 3 bytes hole, try to pack */

unsigned int serial; /* 24 4 */

short unsigned int firmware_rev; /* 28 2 */

/* XXX 2 bytes hole, try to pack */

int addons; /* 32 4 */

Some modesl can support up to 8192 frames per period.

Tested-by: Adrian Knoth <adi@drcomp.erfurt.thur.de>

- ALSA: hdspm - Enable 32 samples/period on RME RayDAT/AIO

Newer RME cards like RayDAT and AIO support 32 samples per period. This

value is encoded as {1,1,1} in the HDSP_LatencyMask bits in the control

register.

Since {1,1,1} is also the representation for 8192 samples/period on

older RME cards, we have to special case 32 samples and 32768 bytes

according to the actual card.

- ALSA: hdspm - Introduce hdspm_get_latency() to harmonize latency calculation

Currently, hdspm_decode_latency is called several times, violating the

DRY principle. Given that we need to distinguish between old and new

cards when decoding the latency bits in the control register, introduce

hdspm_get_latency() to provide the required functionality.

- ALSA: hdspm - Reorder period sizes according to their bit representation

On newer RME cards like RayDAT and AIO, the 8192 samples per period size

are no longer supported. Instead, setting all three bits of

HDSP_LatencyMask to one ({1,1,1}) now corresponds to 32 samples per

period.

To make this more obvious to future developers, let's reorder the array

according to their bit representation, starting at 64 ({0,0,0}) up to

4096 ({1,1,0}) and finally 32 ({1,1,1}).

Note that this patch doesn't change semantics.

- ALSA: hdspm - Set period_bytes_min to 32 * 4 for new RME cards

On newer RME cards like RayDAT and AIO, the lower bound is 32 samples

per period in contrast to 64 samples as seen on older cards.

We hence lower period_bytes_min to 32 * 4. Four bytes per sample.

- ALSA: hdspm - Allow for 8192 period size on RME MADI and AES cards

Older RME cards like MADI and AES support period sizes of 8192 samples.

The original hdspm driver already featured this value, apparently, it

was lost during the rewrite.

- ALSA: hdspm - Fix uninitialized compile warnings

Put the exception checks for io_type switch() for possible mistakes in

future. Also this shuts up annoying compile warnings.

- ALSA: hdspm - Add firmware revision 0xcc for RME MADI

Apparently, there are multiple old firmware revisions in the wild for

the PCI RME MADI cards. Just add them to the list of supported devices

and treat them like their modern counterparts.

- ALSA: hdspm - Fix reported external sample rate on RME MADI and MADIface

In slave mode, the card can only detect the base frequency (32..48kHz)

on the MADI link (exception: 96k frames), so the real external sample

rate is this base frequency multiplied by 1, 2 or 4 depending on the

speed mode.

This patch enables 64..192kHz sample rates in clock slave mode, which

failed before due to an alleged sample rate mismatch between the MADI

link (e.g., 48kHz) and the application in DS/QS mode (e.g., 96kHz,

192kHz).

- ALSA: hdspm - Provide MADI speed mode selector on RME MADI and MADIface

When running in slave mode (no clock master), there is no way to

determine the real wirespeed on the MADI link (single/double/quad

speed). Like physical gear, simply provide the user with a tristate

switch to select the appropriate format.

- ALSA: hdspm - Fix compile warnings with PPC

The char can be unsigned on some architectures. Since the code checks

the negative values, they should be declared as signed char explicitly.

sound/pci/rme9652/hdspm.c:5462: warning: comparison is always false due to limited range of data type

- ALSA: hdspm - Add firmware revision ID for RME MADI PCI version

The PCI version of the RME HDSP MADI card uses 0xcf as revision ID. Just

add this to the list of supported cards.

- ALSA: hdspm - Fix jumping external wordclock frequency in AutoSync mode

When using Word Clock on RME MADI cards, AutoSync mode was alternating

betweeen MADI and WC due to a typo: AutoSync is indicated in the second

status register (status2), not the first one (status).

While the proc output was always correct, the reported WC frequency to

ALSA was unstable as mentioned in

http://mailman.alsa-project.org/pipermail/alsa-devel/2008-March/006723.html

- ALSA: hdspm - Fix locking in snd_hdspm_midi_input_read

For the MIDI part, we need to acquire (and release) the hmidi->lock,

access to the global hdspm structure is serialized through

hmidi->hdspm->lock instead.

- ALSA: hdspm - Add firmware ID for older AES32 cards.

The current AES32 firmware revision ID is 234, however, a user confirmed

that everything works fine with the previous revision, too.

- ALSA: hdspm - Fix midi port initialization

Depending on the model and the presence of a TCO module, the number of

midi ports varies. Some have 1 port (MADIface), some have 2 (default),

with TCO, there are 3.

Don't hardcode the number of midi ports to initialize.

This patch also fixes a boot lockup on MADIface.

[Coding-style fixes by tiwai]

- ALSA: hdspm - Abort on unknown firmware revision

Don't continue if we cannot detect the real card type, otherwise, all

subsequent functions, especially strcpy(), would fail, leaving the whole

driver in an unusable state.

Without such a protection, dmesg would look like this:

- ALSA: hdspm - Add updated firmware revision for AES32

In contrast to the PCIe version (RME AES), the PCI version (RME AES32)

has a different firmware revision.

This patch adds the missing PCI revision.

- ALSA: hdspm - AES32: Use define instead of hardcoded channel count

- ALSA: hdspm - Fix lock/sync reporting on MADI and AES32

- ALSA: hdspm - prevent reading unitialized stack memory

Original patch by Dan Rosenberg <drosenberg@vsecurity.com> under commit

e68d3b316ab7b02a074edc4f770e6a746390cb7d. I'm copying his text here:

The SNDRV_HDSPM_IOCTL_GET_CONFIG_INFO ioctl in hdspm.c allow unprivileged

users to read uninitialized kernel stack memory, because several fields

of the hdspm_config struct declared on the stack are not altered

or zeroed before being copied back to the user. This patch takes care

of it.

- ALSA: hdspm - fix sync check on AES32

Fredrik Lingvall <fredrik.lingvall@gmail.com> has discovered wrong

frequency and sync detection on AES32. According to him, the provided

patch fixes these issues.

- ALSA: hdspm - Remove input selector on MADIface

In contrast to the RME MADI card, coax/optical selection on the MADIface

is done via a physical switch located at the breakout box. Obviously,

the driver cannot switch ports in software.

- ALSA: hdspm - Fix DS/QS output channel mappings on RME MADI/MADIface

Caused by two typos, no output channel mappings were assigned for

MADI/MADIface at double/quad speed.

The channel mapping is indeed identical to the single speed mapping, the

cards will simply use the first N channels.

- ALSA: hdspm - Restrict channel count on RME AES/AES32

Without calling an appropriate rule, AES/AES32 cards would announce a

theoretical channel count of 64 (HDSPM_MAX_CHANNELS), leading to the

already known bug:

the channel count is always 16, no matter of the samplerate in use.

- ALSA: hdspm - Fix buffer handling on RME MADI/MADIface/AES(32)

There are some AC97 codec and board combinations that have been observed

In one case, more than 350 ms was required. To allow users to have sound

on those platforms, we'll wait up to 500ms for the codec to become

ready.

As a board may have multiple codecs, with some faster than others to

reset, we add a module parameter to inform the driver which codecs

should be present.

- treewide: fix potentially dangerous trailing ';' in #defined values/expressions

All these are instances of

#define NAME value;

or

#define NAME(params_opt) value;

These of course fail to build when used in contexts like

if(foo $OP NAME)

while(bar $OP NAME)

and may silently generate the wrong code in contexts such as

foo = NAME + 1; /* foo = value; + 1; */

bar = NAME - 1; /* bar = value; - 1; */

baz = NAME & quux; /* baz = value; & quux; */

Reported on comp.lang.c,

Message-ID: <ab0d55fe-25e5-482b-811e-c475aa6065c3@c29g2000yqd.googlegroups.com>

Initial analysis of the dangers provided by Keith Thompson in that thread.

There are many more instances of more complicated macros having unnecessary

trailing semicolons, but this pile seems to be all of the cases of simple

values suffering from the problem. (Thus things that are likely to be found

in one of the contexts above, more complicated ones aren't.)

SuperH DAC audio driver

- ALSA: convert sound/* to use module_platform_driver()

This patch converts the drivers in sound/* to use the

module_platform_driver() macro which makes the code smaller and a bit

simpler.

TEA575x tuner

- Drop V4L1 support from tea575x-tuner

It was already broken, so safer to drop now.

Also made patches for building with older kernels.

- Fix build of tea575-tuner with older kernels

Copy the old code into alsa-driver tree; too intrusive changes for V4L

- [media] tea575x: remove useless input ioctls

Remove empty and useless g_input and s_input ioctls.

This fixes one fail of v4l2-compliance test.

- [media] tea575x: allow multiple opens

Change locking to allow tea575x-radio device to be opened multiple times.

- [media] tea575x: convert to control framework

Convert tea575x-tuner to use the new V4L2 control framework. Also add

ext_init() callback that can be used by a card driver for additional

initialization right before registering the video device (for SF16-FMR2).

Also embed struct video_device to struct snd_tea575x to simplify the code.

- ALSA: tea575x: use better card and bus names

Provide real card and bus_info instead of hardcoded values.

- ALSA: tea575x: remove unused card from struct

struct snd_card *card is present in struct snd_tea575x but never used.

Remove it.

- ALSA: tea575x: remove freq_fixup from struct

freq_fixup is a constant, no need to hold it in struct snd_tea575x and set in

each driver.

- ALSA: tea575x: unify read/write functions

Implement generic read/write functions to access TEA575x tuners. They're now

implemented 4 times (once in es1968 and 3 times in fm801).

This also allows mute to work on all cards.

Also improve tuner detection/initialization.

- ALSA: tea575x-tuner: remove dev_nr

Remove unused dev_nr from struct tea575x_tuner.

- ALSA: tea575x-tuner: various improvements

Improve tea575x-tuner with various good things from radio-maestro:

- extend frequency range to 50-150MHz

- fix querycap(): card name, CAP_RADIO

- improve g_tuner(): CAP_STEREO, stereo and tuned indication

- improve g_frequency(): tuner index checking and reading frequency from HW

- improve s_frequency(): tuner index and type checking

USB

- Update usb/endpoint.patch and usb/stream.patch

For upstream commit ca7051d40da5e86e3c249b5a41ac82bb1016c044

- ALSA: snd-usb-caiaq: Add support for Maschine

This adds partial support for the Maschine controller by Native Instruments.

Supported now are the 1x1 MIDI interface and the 41 buttons, 11 endless

rotary encoders, and 16 pressure-sensitive drum pads. Still to work on are the

dimmable LEDs and the two monochrome screens.

- ALSA: snd-usb: move code from urb.c to endpoint.c

No code altered at this point, simply preparing for upcoming

USB Edirol UA101 driver

- USB: convert sound/* to use module_usb_driver()

This converts the drivers in sound/* to use the

module_usb_driver() macro which makes the code smaller and a bit

simpler.

Added bonus is that it removes some unneeded kernel log messages about

drivers loading and/or unloading.

- ALSA: ua101: fix crash when unplugging

If the device is unplugged while running, it is possible for a PCM

device to be closed after the disconnect callback has returned. This

means that kill_stream_urb() and disable_iso_interface() would try to

access already-invalid or freed USB data structures.

The function free_usb_related_resources() was intended to prevent this,

but forgot to clear the affected variables.

- ALSA: firewire-speakers, oxygen, ua101: allow > 10 s periods

Since commit f2b3614cefb6 (Don't check DMA time-out too shortly),

drivers need no longer restrict their PCM period length to be shorter

USB TerraTec DMX 6Fire

- USB: convert sound/* to use module_usb_driver()

This converts the drivers in sound/* to use the

module_usb_driver() macro which makes the code smaller and a bit

simpler.

Added bonus is that it removes some unneeded kernel log messages about

drivers loading and/or unloading.

- ALSA: 6fire: don't use custom hex_to_bin()

- ALSA: 6fire - Fix signedness bug

Fixed remaining issues of the signedness bug discovered by Dan Carpenter.

A check was remaining that tests if unsigned rt->rate is >= 0.

Changed that so that rt->rate now consistently uses ARRAY_SIZE(rates)

as invalid rate value and not -1.

- ALSA: 6fire: Fix double-free bug in usb6fire_fw_ezusb_upload()

We have a double-free bug in

sound/usb/6fire/firmware.c::usb6fire_fw_ezusb_upload().

We already call release_firmware(fw) on line 258, so when we then do it

again after usb6fire_fw_ezusb_write() returns <0, we have a double-free.

Easily fixed by just removing the last call to release_firmware().

- ALSA: 6fire: Don't leak firmware in error path

One of the error paths in

sound/usb/6fire/firmware.c::usb6fire_fw_ezusb_upload() neglects to free

the memory allocated for the firmware before returning, thus leaking the

memory.

- ALSA: 6fire: use the kernel's built-in bit reverse table

- ALSA: 6fire - Add support of digital-thru mixer

Digital Thru mixer element added (device can act as converter optical<->coax)

- ALSA: 6fire - Improve firmware loader

Firmware loader: magical device bytes check updated (accepts all device

versions now and accepts possibly loaded firmware, if it is knowing to

be working)

- ALSA: 6fire - Add support for S32_LE format

Added support for sample format s32_le.

- ALSA: 6fire - Fix pcm rate assignment

Completion of signedness bug for pcm_runtime.rate: variable will never

get assigned a negative value now.

- ALSA: USB: 6fire: signedness bug in usb6fire_pcm_prepare()

rt->rate is an unsigned char so it's never equal to -1. It's not a huge

problem because the invalid rate is caught inside the call to

usb6fire_pcm_set_rate() which returns -EINVAL. But if we fix the test

then it prints out the correct error message so that's good.

USB USX2Y

- Rediff the usbusx2y.c and soc-core.c patches to match recent kernel

- ALSA: snd-usb-us122l: Delete calls to preempt_disable

They are not needed here.

- USB: convert sound/* to use module_usb_driver()

This converts the drivers in sound/* to use the

module_usb_driver() macro which makes the code smaller and a bit

simpler.

Added bonus is that it removes some unneeded kernel log messages about

drivers loading and/or unloading.

- sound: add moduleparam.h to users of module_param/MODULE_PARM_DESC

These files were getting access to these two via the implicit

presence of moduleparam.h everywhere. But that is being fixed, so

get these guys what they need in advance.

USB caiaq

- Refreshed patches

Mainly for bool modparm changes.

- Regenerate patches to fix fuzz for 3.2-rc1 changes

- USB: convert sound/* to use module_usb_driver()

This converts the drivers in sound/* to use the

module_usb_driver() macro which makes the code smaller and a bit

- ALSA: snd-usb-caiaq: Fix NULL dereference in input.c

There was a case where a newly-registered input device could be opened before

a necessary variable in the device structure was set. When code tried to use

the variable in the URB reply callback, it would cause an Oops.

This fix sets the aforementioned variable before calling input_register_device.

- ALSA: snd_usb_caiaq: track submitted output urbs

The snd_usb_caiaq driver currently assumes that output urbs are serviced

in time and doesn't track when and whether they are given back by the

USB core. That usually works fine, but due to temporary limitations of

the XHCI stack, we faced that urbs were submitted more than once with

this approach.

As it's no good practice to fire and forget urbs anyway, this patch

introduces a proper bit mask to track which requests have been submitted

and given back.

That alone however doesn't make the driver work in case the host

controller is broken and doesn't give back urbs at all, and the output

stream will stop once all pre-allocated output urbs are consumed. But

it does prevent crashes of the controller stack in such cases.

See http://bugzilla.kernel.org/show_bug.cgi?id=40702 for more details.

With some buggy devices, the usb-audio driver may give "frame xxx active"

kernel messages too often. Better to keep it as debug-only using

snd_printdd(), and also add the rate-limit for avoiding floods.

Bugzilla: https://bugzilla.novell.com/show_bug.cgi?id=738681

- ALSA: usb-audio: fix possible hang and overflow in parse_uac2_sample_rate_range()

A malicious USB device may feed in carefully crafted min/max/res values,

so that the inner loop in parse_uac2_sample_rate_range() could run for

a long time or even never terminate, e.g., given max = INT_MAX.

Also nr_rates could be a large integer, which causes an integer overflow

in the subsequent call to kmalloc() in parse_audio_format_rates_v2().

Thus, kmalloc() would allocate a smaller buffer than expected, leading

to a memory corruption.

To exploit the two vulnerabilities, an attacker needs physical access

to the machine to plug in a malicious USB device.

This patch makes two changes.

1) The type of "rate" is changed to unsigned int, so that the loop could

stop once "rate" is larger than INT_MAX.

2) Limit nr_rates to 1024.

In the recent usb-audio driver, the initialization of volume ranges

may be delayed when the device doesn't respond well at the probing time.

But the volume quirks for certain devices are applied only in

mixer_ctl_feature_info() thus only at the very first probe and will be

missing when the volume range is initialized later.

This patch moves the volume quirk code to be always called from the

volume-range extraction (get_min_max()), so that the quirks are properly

applied in the later init time.

The audio_feature_info[] array should contain all entries for UAC2_FU_*,

access the range over the array. This patch fixes the bug by limiting

the loop size properly using ARRAY_SIZE() instead of a hard-coded

magic number.

- ALSA: usb-audio: Check for possible chip NULL pointer before clearing probing flag

Before clearing the probing flag in the error exit path, check that the

- ALSA: usb-audio - clear chip->probing on error exit

The Terratec Aureon 5.1 USB sound card support is broken since kernel

2.6.39.

2.6.39 introduced power management support for USB sound cards that added

a probing flag in struct snd_usb_audio.

During the probe of the card it gives following error message :

usb 7-2: new full speed USB device number 2 using uhci_hcd

cannot find UAC_HEADER

snd-usb-audio: probe of 7-2:1.3 failed with error -5

input: USB Audio as

on usb-0000:00:1d.1-2/input3

I can not comment about that "cannot find UAC_HEADER" error, but until

2.6.38 the card worked anyway.

With 2.6.39 chip->probing remains 1 on error exit, and any later ioctl

stops in snd_usb_autoresume with -ENODEV.

- ALSA: usb-audio: Added support for Roland UM-ONE midi-usb interface

- ALSA: usb: refine delay information with USB frame counter

Existing code only updates the audio delay when URBs were

submitted/retired. This can introduce an uncertainty of 8ms

on the number of samples played out with the default settings,

and a lot more when URBs convey more packets to reduce the

interrupt rate and power consumption.

This patch relies on the USB frame counter to reduce the

uncertainty to less than 2ms worst-case. The delay information

essentially becomes independent of the URB size and number of

packets. This should help applications like PulseAudio which

require accurate audio timing. Clemens Ladisch reported

a decrease of mplayer's A-V difference from nrpacks down to at

most 1ms.

Thanks to Clemens for also pointing out that the implementation

of frame counters varies between different HCDs. Only the

8 lowest-bits are used to estimate the delay.

- PM / Runtime: Add macro to test for runtime PM events

This patch (as1482) adds a macro for testing whether or not a

open-coding the test all over the place.

- ALSA: usb-audio - Check the dB-range validity in the later read, too

When the initial check of dB-range failed due to the read error, try to

check again at the later read, too. When an invalid dB range is found,

remove TLV flags and notify the mixer info change.

- ALSA: usb-audio - Fix missing mixer dB information

The recent fix for testing dB range at the mixer creation time seems

to cause regressions in some devices. In such devices, reading the dB

info at probing time gives an error, thus both dBmin and dBmax are still

zero, and TLV flag isn't set although the later read of dB info succeeds.

This patch adds a workaround for such a case by assuming that the later

read will succeed. In future, a similar test should be performed in a

case where a wrong dB range is seen even in the later read.

- ALSA: usb-audio - Add quirk for Roland / BOSS BR-800

Add support for Roland/BOSS BR-800 (0582:011e) to snd-usb-audio driver.

This allows playback and recording, which has been tested and found to

work. The third interface should be MIDI (MTC/SMPTE?) for DAW interface

and is set as per ME-25, but this has not been tested. SDHC card access

is already supported by usb-storage for Backup/Rhythm Editor/Wave

Convertor mode which should not conflict with this.

- ALSA: usb-audio - Add quirks for M-Audio Fast Track Pro and Quattro

This patch gives M-Audio Fast Track Pro and M-Audio Quattro quirks and

endpoints to boot and setup those devices with special options (digital

inputs and outputs, 24 bits mode, etc...). M-Audio Audiophile quirks are

just adapted to match the new global M-Audio parameters.

Special configurations can be then loaded through a modprobe conf file.

For example, to set the 24 bits mode on the Fast Track Pro add

/etc/modprobe.d/fast_track_pro.conf :

options snd_usb_audio vid=0x763 pid=0x2012 device_setup=0x08

- ALSA: usb-audio: add new quirk type QUIRK_AUDIO_STANDARD_MIXER

This quirk type will let the driver assume that there is a standard

mixer on a given interface, or that a specific mixer quirks will handle

the device.

- ALSA: usb-audio: export snd_usb_feature_unit_ctl

In order to allow quirks functions to hook up to the standard feature

unit op tables, this patch exports a pointer to the struct that is used

internally.

That way, all the code handling the control can be kept private, and

external code can reference the symbol to re-use it.

- ALSA: usb-audio: rework add_control_to_empty()

This patch renames add_control_to_empty() to snd_usb_mixer_add_control()

and exports it, so the quirks functions can make use of it.

Also, as "struct mixer_build" is private to mixer.c, rewrite the

function to take an argument of type "struct usb_mixer_interface"

instead.

- ALSA: usb-audio: move assignment of chip->ctrl_intf

- ALSA: usb-audio - Don't expose broken dB ranges

Some crappy USB-audio devices give broken dB ranges, e.g. both min and max

are 0dB. This confuses the volume control that prefers dB expression such

as alsactl or PulseAudio. In such a case, it's much better not to expose

the broken dB information.

- ALSA: usb-audio: Add quirks for Audio Kontrol 6

This new device by Native Instruments is also compliant to the USB

standard v2.0, but hides this detail at when connected.

It needs the same boot quirks than other models, and also has two

non-class-compliant mixer controls.

- ALSA: usb-audio: define another USB ID for a buggy USB MIDI cable

One more affected devices: Logitech Webcam C600 (046d:0808)

Volume range before quirk is 6400, after (also real) is 16.

- ALSA: usb-audio - Add volume range check and warn if it too big

- ALSA: usb-audio: fix oops due to cleanup race when disconnecting

When a USB audio device is disconnected, snd_usb_audio_disconnect()

kills all audio URBs. At the same time, the application, after being

notified of the disconnection, might close the device, in which case

ALSA calls the .hw_free callback, which should free the URBs too.

Commit de1b8b93a0ba "[ALSA] Fix hang-up at disconnection of usb-audio"

prevented snd_usb_hw_free() from freeing the URBs to avoid a hang that

resulted from this race, but this introduced another race because the

URB callbacks could now be executed after snd_usb_hw_free() has

returned, and try to access already freed data.

Fix the first race by introducing a mutex to serialize the disconnect

callback and all PCM callbacks that manage URBs (hw_free and hw_params).

- ALSA: usb-audio: add support for Native Instruments MK2 devices

The MK2 generation of Native Instruments' sound cards are in fact

compliant to the USB audio standard of version 2 and other approved USB

standards. However, they come up as vendor-specific device when first

connected but can be told to come up with a new set of descriptors

upon their next enumeration. The interfaces announced by the new

descriptors will be handled by the kernel's class drivers. This is done

by issuing a vendor specific device request and sending the device to

reset.

There are also some vendor-specific USB requests for some mixer elements

that can't be exported in a standard compliant way. The driver now

supports them with quirks handling mechanisms.

- ALSA: usbaudio - Enable the E-MU 0204 USB

- conf: Allow for a directory to be given as a config file.

When this is done, *.conf files can be placed in that directory and they

will be processed by as if they were included directly.

A directory (typically /usr/share/alsa/alsa.conf.d/) has been

added into the distribution.

v2: Used existing conf syntax rather than processing via autotools

v3: Split file loading into separate function and made error handling

more consistent.

- configure: Fail when the user attempts to compile shared and static libs

There are some issues with libtool breaking the possibility to build both

types of libraries in one shot. Compile libraries separately.

- Release v1.0.24.1

Control API

- Document strdup allocation in snd_card_get_name family

This was spotted by Jörg Höhle on the wine-patches ML.

- Improve snd_device_name_hint documentation

- control: add snd_ctl_elem_add_enumerated()

Handling of user control elements was implemented for all types except

BYTES and ENUMERATED. Enumerated user controls will be needed for the

device-specific mixers of upcoming FireWire drivers.

- Add snd_{ctl|pcm}_open_fallback() functions

This patch adds new API functions, snd_ctl_open_fallback() and

snd_pcm_open_fallback(). These are just like snd_*_open_lconf() but

used to open a fallback PCM/control. The difference is that it replaces

the name string with the given original name, so that hctl and other

upper-layers will recognize it as an alias.

- Fix missing error code in snd_ctl_hw_open()

- ctlparse: Respect softfloat configure option

If we want softlfoat we can't use ceil which uses libm.

Device Name API

- Remove docs for snd_names_list and snd_names_list_free

simple_none.c: In function ‘base_len’:

simple_none.c:940:33: warning: ordered comparison of pointer with integer zero

simple_none.c:941:29: warning: ordered comparison of pointer with integer zero

- Fix alsa-lib to regard 3D control - Depth as Playback Controls

This allow those mixer or recording application to find those controls which

are really used for capturing.

PCM API

- Improve hw_params documentation

- Search-and-replace improve documentation language

- pcm:mmap_emul: Fix sw_params and others in bypass mode

When the slave doesn't need any mmap-emulation, the plugin shouldn't do

anything special in sw_params and other callbacks but just pass to the

generic helpers and update hwptr and applptr.

- src/pcm/pcm_mmap.c: add missing free

The mmap_channels and running_areas fields are allocated using calloc, but

are not freed on an error path.

- src/pcm/pcm_multi.c: add missing free

Something that is allocated using calloc is not freed on an error path.

- src/pcm/pcm_ladspa.c: add missing free

Something that is allocated using calloc is not freed on some

error paths.

- src/pcm/pcm_rate.c: add missing free

Something that is allocated using calloc is not freed on one

or more error paths.

- pcm: recalculate all rules after changing hw_params flags

The rules engine avoids recalculating rules that do not depend on

any changed parameter, but there is no mechanism to record changed

flags. So when we change a flag, we have to ensure that all rules

depending on that flag are recalculated; the only method to do this

is to force recalculation of all rules.

So far, there have been no kernel drivers with rules depending

on flags, but rules to disable hardware SRCs by setting

SND_PCM_HW_PARAMS_NORESAMPLE are being introduced now.

- Add snd_{ctl|pcm}_open_fallback() functions

This patch adds new API functions, snd_ctl_open_fallback() and

snd_pcm_open_fallback(). These are just like snd_*_open_lconf() but

used to open a fallback PCM/control. The difference is that it replaces

the name string with the given original name, so that hctl and other

upper-layers will recognize it as an alias.

- ucm: add another sequence 'msleep'

Thus, we have two sleep statements:

msleep <milliseconds>

- ucm: tivial code style fix

- ucm: fix seg fault in execute_cset()

When there's no space in 'cset', 'pos' gets NULL, dereferencing 'pos' gets a

seg fault. We need to be more robust.

- UCM: get: Implement 'exact' value retrieval

[=]<NAME>[/[<modifier>|</device>][/<verb>]]

- value identifier <NAME>

- Search starts at given modifier or device if any,

else at a verb

- Search starts at given verb if any,

else current verb

- Searches modifier/device, then verb, then defaults

- Specify a leading "=" to search only the exact

device/modifier/verb specified, and not search

through each object in turn.

- Examples:

"PlaybackPCM/Play Music"

"CapturePCM/SPDIF"

From ValueDefaults only:

"=Variable"

From current active verb:

"=Variable//"

From verb "Verb":

"=Variable//Verb"

From "Modifier" in current active verb:

"=Variable/Modifier/"

From "Modifier" in "Verb":

"=Variable/Modifier/Verb"

- UCM: snd_use_case_get: Don't segfault when no current verb

get_value, called by snd_use_case_get, uses uc_mgr->active_verb without

checking there is one, and hence can segfault. Fix this.

- UCM: Allow querying of {Supported,Conflicting}Devices

At any time, one can query:

_supporteddevs/<modifier>|<device>/<verb>

_conflictingdevs/<modifier>|<device>/<verb>

If a verb is current, one can query:

_supporteddevs/<modifier>|<device>

_conflictingdevs/<modifier>|<device>

Note that at most one of the supported/conflicting devs lists has

any entries, and when neither is present, all devices are supported.

- UCM: Disallow gets of undefined system properties

In UCM, there are various system-defined properties whose names start

with "_". Explicitly prevent any gets from falling back to properties

defined in a config file if the property name starts with "_", in order

to reserve the entire "_" namespace for system-defined properties.

- UCM: Implement ConflictingDevices, add device list to devices

Wherever SupportedDevice can appear, also allow ConflictingDevice. Only

one or the other (or neither) may be specified. When neither is

specified, allow anything. Sometimes, listing ConflictingDevices may

result in a shorter list than explicitly listing all SupportedDevices.

Add support for SupportedDevice and ConflictingDevice to SectionDevice.

This allows representing devices which are mutually exclusive, e.g. due

to a mux that switches between capturing from two different microphones,

without the possibility of mixing.

Enhance is_modifier_supported to allow ignoring SupportedDevice and

ConflictingDevice. This is useful when querying values from a

SectionModifier; there's no reason we shouldn't be able to query values

just because the current configuration would prevent enabling that

device. The new is_device_supported is implemented similarly.

Enhance switch_device to remove the old device from the current device

list before querying for the new device, and add it back immediately

afterwards. This allows the query for the new device to ignore any

conflicts caused solely by the old device.

- UCM: Deprecate index on Section{Device,Modifier}

The previous supported "legacy" syntax was:

SectionDevice."Speaker".0 {

SectionModifier."Capture Voice".0 {

This change supports new syntax:

SectionDevice."Speaker" {

SectionModifier."Capture Voice" {

... but also allows the old syntax, iff the index is exactly "0". If an

index is present, but not exactly "0", parsing will appear to succeed,

but produce an empty device or modifier.

When naming devices and modifiers, even if the legacy format is used,

any index is not included in the name; i.e. both sets of syntax above

name the device just "Speaker".

The SupportedDevice list syntax still also accepts either "x" or "x.0",

but internally strips ".0" from the tail of any device name. Any other

name including "." is disallowed.

Finally, when comparing device or modifier names, a simple exact string

compare is now used, since no index data is ever present in device or

modifier names.

The one functional change introduced here is that a SupportedDevice

entry of just "x" will now only ever match a single device. It previously

acted as a wildcard for any device named "x.foo".

- UCM: Fix deadlock following failed get _verb

When querying the current verb without a verb set, snd_use_case_get bails

out early without unlocking uc_mgr->mutex. This causes subsequent API calls

to hang. Instead, s/return/goto __end/.

- UCM: Fix typo in error message

parse_name_is_safe disallows dots in the name, so not is the correct

word to use

- UCM: fix memory leak when executing cset commands

Also fix a little formatting.

- ucm: add more error messages for cdev and cset commands

- ucm: allow bind modifier to specific instances, other fixes

- ucm: make verb comments optional

avoid seg fault if no comment is provided

Configuration

- conf: Allow for a directory to be given as a config file.

When this is done, *.conf files can be placed in that directory and they

will be processed by as if they were included directly.

A directory (typically /usr/share/alsa/alsa.conf.d/) has been

added into the distribution.

v2: Used existing conf syntax rather than processing via autotools

v3: Split file loading into separate function and made error handling

more consistent.

- Define "sysdefault" PCM and control

When "default" PCM and control definitions are overwritten by others

like PulseAudio setup, the original system-default defition is lost.

This is a problem when PA is temporarily (or intentionally) disabled

and user wants to use the default dmix.

This patch adds a new standard definition for the system-default,

"sysdefault". This can be used for fallbacks.

- emu10k1.conf - Fix no sound problem when using SB Live! Platinum

- alsactl init: Mute CD Playback volume by default

The CD analog playback line is seldom used these days, as all

modern players rip the CD and use the DAC on the sound card.

In addition, it causes background hum on some machines.

Therefore keep it muted by default.

alsamixer

- alsamixer: Fix X-win related crash for PulseAudio plugin (bad linking)

A lot of reports that alsamixer crashes in X terminal when the PulseAudio

CTL plugin is activated were entered to the tracking systems.

I figured that there is a linking clash for the shutdown() function.

The shutdown() function in glibc is socket related, but the alsamixer code

redefines this function and appearently that under some linking

circumstances - which PA client invokes during the runtime dynamic linking

- the wrong function is called.

This patch, for safety, renames the shutdown() function from alsamixer

to app_shutdown(), but it might make sense to figure the real linking

culprit to avoid future surprises.

- alsamixer: Fix 64bit issues

lrint() returns a long int.

- alsamixer: fix build on uClibc

exp10 is a glibc extension, which isn't supported on uClibc. Luckily,

exp10() is trivial to compute based on exp(), so add a wrapper for

the uClibc case.

- alsamixer: fix display of active/inactive controls

alsaucm

- alsaucm: Don't double-free empty lists

When snd_use_case_get_list (and hence also snd_use_case_card_list) returns

an empty list, alsaucm still attempts to free it. This ends up double-

freeing the returned list, or worse, freeing an invalid pointer, depending

on how snd_use_case_get_list gets implemented. Fix alsaucm to return early

on empty lists to avoid this.

- alsaucm: Add list1 command for non-tuple lists

snd_use_case_get_list returns lists of strings that are either:

a) A sequence of single strings

b) A sequence of pairs of strings all flattened into a single list

The current list command assumes layout (b) above, and hence prints

nothing when printing a single-entry list that's actually in layout (a).

Add a new command "list1" to dump lists in layout (a).

- aplay: increase channel limit to 256

aplay is limited to 32 channels, which makes it impossible to use it for

testing devices with more channels. here we increase the limit to 256,

which should be sufficient for a virtual device made of 4 64-channel

soundcards.

- aplay: Use standard endian convesions

- aplay: Add include files for mkdir()

- aplay: Avoid recursive signal handling

When abort() is issued in snd_pcm_close() path, it may loop recursively

- aplay: Add -i option for interactive mode

The recent addition of pause/resume control via keyboard brought

a problem when aplay/arecord is invoked in background. For avoiding

regressions, it's safer to use non-interactive mode as default and

enable the new feature via an option.

files.

RPM in HDSP_IO_Type (enum from hdsp.h) is 4, not 5.

- hdsploader: Temporary define for RPM

Right now (1.0.24.1), alsa-lib's hdsp.h doesn't know about the RPM. To

avoid a strong dependency on unreleased code, temporary provide the

define here.

It can be dropped as soon as a new version of alsa-lib will be released,

thus effectively making it the required minimum version for alsa-tools.

hdspmixer

- hdspmixer: Fix temporary RPM constant

RPM in hdsp.h's HDSP_IO_Type is 4, not 5. This patch isn't exactly

necessary here, because the constant is only used internally, but to

avoid confusion if somebody ever reads the code, let's use the correct

value.

Note that we'll drop it after the next alsa-lib release.

- hdspmixer: Add support for RME RPM

This patch adds support for the RME RPM devices. It's mostly based on

Florian Faber's previous patch against hdspmixer 1.0.23,

forwarded-ported to the current hdspmixer code.

- hdspmixer: Handle preset files used in 1.0.24 and 1.0.24.1

As an addition to the previous commit, let's also cover the 3rd case

when a preset file was written with hdspmixer v1.0.24 or v1.0.24.1.

In this case, no magic header will be present, but the file size would

differ from the pre 1.0.24 format.

- hdspmixer: Handle channel count in old (v1.0.23) preset file format

When reading a preset file, v1.0.23 only used 26 channels instead of 64.

Reading 64 channels from a 26 channel file won't work, hence set it

depending on the file format version.

- hdspmixer: Fix read/write from/to preset files on MADI-like cards

The old hdspmixer (prior to e24e56795ea57e3dd7da45063ab71f04e231192d,

that is pre-1.0.24) has used the hard-coded value "14" for

reading/storing 14 ints from/to preset files, however, it's actually

HDSP_MAX_DEST that should be used.

HDSP_MAX_DEST was bumped from 14 to 32 to allow for MADI cards (32

stereo pairs equal 64 output channels on MADI cards)

- hdspmixer: Initialize headphones out in presets

Cards like the multiface/digiface have additional headphones out. Those

were not initialized in the presets due to wrong loop boundaries:

maxdest represents the amount of physical stereo pairs, and chnls is

either equal or less, so the output fader array needs more iterations

than the playback section.

- hdspmixer: Recall 1st preset on all cards, not just on the first

With the new "store current settings to the virtual 9th preset" before

switching cards code, one needs to make sure the actual mixer state is

loaded with sane values, either from the preset file or a generic

builtin preset.

Calling preset_change(1) is sufficient, setting all the required data.

However, in case of more than one RME card in the system, one needs to

call this function for each card, otherwise, some of the cards store

uninitialized data to the 9th preset, resulting in a weird mixer state

afterwards.

- hdspmixer: Save preset before switching cards

When running with more than one card, switching cards would lose any

changes made to the current card. To avoid this inconvenience, save the

current settings to the virtual 9th preset and restore them when

switching back.

- hdspmixer: Add a 9th pseudo preset

When switching cards, all current settings are lost. To have a place

where to store them, let's add a virtual 9th preset which can be used as

a temporary scratch pad.

- hdspmixer: fix drawing problems with black background

- use foreground color instead of black

- HDSPMixerSelector: set colors before setting labels

Reviewed-by: Paul Menzel <paulepanter@users.sourceforge.net>

- hdspmixer: Update NEWS file.

- hdspmixer: Save and restore level meter settings

Each preset can have a different level meter setting (FS samples for

OVR, release rate, minimum level and so on).

These settings were not saved/restore to/from the on-disk file. This

patch adds the missing functionality.

Unfortunately, the current on-disk format is a 1:1 binary dump from

memory without any header information. In other words, this commit will

break backward compatibility with older hdspmixers, that is, new preset

files cannot be read by older versions of hdspmixer. However, we can

still read the old mix files and save them in the new format.

I hence bumped the version, so users know to re-create their files after

upgrading to 1.11.

Bug discovered by Raphaël Doursenaud from ematech.fr.

- hdspmixer: Use constant instead of hardcoded number of cards.

- hdspmixer: New pixmaps

Reuben Martin has provided me with an updated pixmap set to replace

RME's 1998 style no longer in use by the corresponding Win32 tools.

The Linux pixmaps are based on ardour2. Likewise hdspmixer, ardour2 is

GPLv2.

- hdspmixer: Show cardname in window title

When running with more than one card, it isn't obvious which card is

shown.

Store the ALSA cardname in the corresponding class and show it in the

window title upon switching cards.

Also, don't show "(null)" but "(unsaved)" in case the user hasn't

selected a preset file.

- hdspmixer: [cosmetics] Break code into logic blocks

Convert the if-then-else-if chain into standalone if-then blocks to

improve readability. A switch-case statement would also do the trick,

but it's less readable.

No (intended) semantic change.

- hdspmixer: Fix code indentation

Only cosmetics, no changed semantics. Indent the whole function to get

rid of a mixture of tabs and spaces.

- hdspmixer: Provide headphones out on Multiface/Digiface

Both, Multiface and Digiface feature a separate headphone submix, so

reflect this additional pair of channels in the corresponding maps.

- hdspmixer: Introduce output channel count for all cards.

Some cards (like multiface) have more physical output ports than

playback ports, mostly because of additional headphones out.

For those cards, the old abstraction model of channels_input and

channels_output doesn't fit, so let's introduce channels_output.

Of course, channels_output is always 2*max_dest at the given speed_mode

(SS/DS/QS), so one could extend this idea, store all destination

settings in channels_output[3] (one for each speed mode) and rip off the

massive code duplication for setting maxdest or max_dest respectively.

Note that dest_map_whatever_speed_mode's array size indirectly defines

the right value for channels_output (read: even more unwanted

redundancy)

- hdspmixer: Adjust playback channel count on Multiface.

The multiface has 18/14 (SS/DS) playback channels, matching the native

18/14 I/O ports. Headphones don't count (only for #destinations).

- hdspmixer: Fix preset activation segfault on AES(32)

When selecting preset 6 or 7 on AES(32), hdspmixer has caused a segfault

due to indirect out of bound access on the destination label array.

The amount of destinations is the number of physical stereo

pairs, so it's usually half the channel count, in some cases one more if

there are additional headphone jacks.

- hdspmixer: Replace hardcoded 3 by MAX_CARDS

We have a define for the number of cards. Use it.

- hdspmixer: Fix labels on H9652

The H9652 uses the same layout as the Digiface, except Digiface features

an additional headphones out. That's why the channel mappings are the

same, but Digiface has mexdest=14 while H9652 has maxdest=13 (12 ADAT

pairs, another pair for S/PDIF and headphone-L/R on Digiface)

- hdspmixer: Lower nesting depth in label assignment

This fix is mostly cosmetic, the long if-then-else-if-chain was rather

confusing. To improve code readability, use simple if-then statements

and leave the function as soon as a match is found.

Clear code would probably use a two-dimensional map, but it seems rather

overengineered.

Last but not least, the non-matching case was augmented by assigning a

generic "1", "2", "3" .. channel naming schema to prevent hdspmixer from

crashing.

- hdspmixer: Make static destination maps extern

To prevent multiple inclusion, make the destmaps global and only

reference them via extern.

- hdspmixer: Don't use hardcoded number of cards.

We have introduced MAX_CARDS before to make the code more safe and

extendable, so it's just sane to use it all over the place.

- hdspmixer: Fix compiler warnings.

All compiler warnings were caused by a conversion from "foo" to a

char pointer. Given that the string itself really is constant, simply

add the keyword to make g++ happy.

- hdspmixer: Fix metering for non-MADI cards

Currently, hdsp and hdspm use different ioctls. Consequently, the metering

is wrong. To avoid code duplication, use pointers to the corresponding

struct members.

- hdspmixer: Fix ALSA snd_ctl_open error when running with three cards.

If three (or more) RME cards are installed in one box, hdspmixer will

try to open a non-existing 4th card, causing an error in snd_ctl_open

and finally terminates itself.

cards[] is a static array, and one must not read beyond the last

element. The solution is far from elegant, however, it's a rather

unintrusive change.

- hdspmixer: Bump version number to 1.10

Florian Faber's last hdspmixer64 version was 1.9, so let's make this the

successor (contains everything that was in 1.9 and also Fredrik's work

on AES(32) support)

- hdspmixer: Increase height of about window.

The copyright list got longer, so we need more vertical space.

- hdspmixer: Update FSF address.

The FSF has moved, so reflect this change in the about dialogue.

See also http://www.fsf.org/about/contact/

- hdspmixer: Improve code coherency

Move channelmappings into one place (channelmap.h). Also, use "aes32"

when referring to the card itself to avoid confusion and to be coherent

with the remaining naming scheme.

This work has mainly been done by Fredrik Lingvall.

Kevin Ross <kevin@familyross.net> writes:

The cause: The plugin creates a pipe, so that the fd's could be

polled to indicate completion of a transfer. However, the call to

write() blocks when playing audio, as nothing actually reads from the

pipe, and it fills up until it blocks.

Making the socket non-blocking fixes the problem, and testing with

playback and capture both work properly for me now.

Original patch from David Henningsson <david.henningsson@canonical.com>

If more data has already been written after the underrun, the underrun

will automatically end and therefore we should not report it or

restart the stream.

[ This patch adds a more check of underrun with a new PA function so

that the underrun handles works more reliably. As the feature is

supported only in a recent version of PA, the underrun handling is

enabled as default now for the new PA, while it's still disabled for

older PA. -- tiwai ]
