[edit] PulseAudio -> ALSA plugin

- Reindent to Linux kernel style

The PulseAudio plugin was horrible mix-up of different indenting styles even in

the same files. Indenting by 4, by 2, by 8 characters, sometimes with tabs,

sometimes with spaces. To fix this chaos I ran all files through "indent -kr

-i8". Hopefully future patches will follow kernel style indenting too.

- Add Emacs-style /*-*- linux-c -*-*/ header comment

As suggested in the kernel's CodingStyle document force Emacs into kernel-style

indenting to prevent future indenting chaos, at least for Emacs users.

- Make pulse_new() a proper C function

C functions taking no argument need a (void) as argument list. It's C++ where

() is allowed too.

- Don't modify the SIGPIPE handler

Since quite a while (2 years or so) PulsAudio doesn't require SIGPIPE anymore

to be set to SIG_IGN. Since resetting this was incredibly ugly in the first

place it is now time to get rid of this.

- Call pa_context_disconnect() explicitly

Make sure the pa_context is disconnected when we unref it. This is also done

implicitly when the last reference to the pa_context is dropped, but that might

be later then expected in case someone else took a reference on our object. To

make sure that the pa_context will than not make any call into our code,

disconnect it explicitly.

- use SNDERR instead of fprintf to print error messages

We shouldn't spam on stderr unconditionally, so let's use ALSA subsystem for

printing errors.

- Support S32 sample types

PulseAudio has been supporting these for a while, so let's make use of them

here.

- Add trailing NUL character to snprintf output

snprintf doesn't necessarily append a trailing NUL to the strings it writes. So

let's do it explicitly.

- Get rid of pulse_poll_revents()

pulse_poll_revents() has no real purpose, so let's remove it.

- Add more error checking

Add a bit more error checking where necessary

- Remove fix for bug 0003470

This fix is completely broken (introduces new segfaults) and the assert is

tries to fix is superfluous anyway, so let's just remove this altogether.

- Rework hardware parameter selection

Follow more closely the real limits of PulseAudio's API.

- A bag of minor clean ups for ctl_pulse.c

Use more error checking where applicable, optimize a few things, use PulseAudio

API functions for comparing pa_cvolume structures.

- Make pulse_ext_callback const

We can make our instance of snd_ctl_ext_callback_t const without any problems,

so let's do it.

- Drop our own implementation of the poll() callbacks

The ctl extension interfaces support poll() via a single file descriptor

anyway, so let's use it instead of rolling our own poll support callbacks.

- A bag of minor clean-ups for pulse.c

Use more error checking where appropriate, optimize a few things.

- Split out O_NONBLOCK setting into seperate function

Since we set O_NONBLOCK more than once, make it a nice and correct function.

- Save a byte of memory

Since we only need a single char, we should allocate only a single char,

instead of a string of two bytes.

Woah! We're saving memory, baby!

- Adjust buffering metrics to match what PA internally uses

Follow more closely the buffering metrics PA uses internally. This avoids

clamping of the metricsin PA internally.

- Make sure we always have a sensible channel mapping

If PA doesn't know a default channel map for the specified number of channels,

synthesize one by extending a known one with a smaller channel number.

- Use PA_STREAM_EARLY_REQUESTS if available

Use PA_STREAM_EARLY_REQUESTS if PA knows it. PA >= 0.9.12 learned this flag

which will make the buffering more similar to traditional fragment/period-based

scheduling. Instead of delaying buffer fillup until the latest moment possible

this will cause fillups much earlier.

This is useful for compatibility for broken ALSA clients that don't care about

'readability' of the ALSA fd but instead schedule audio via usleep() or a

similar call. (One exampler being mplayer)

- Use S32/FLOAT32 only where available in the PA libs

S32 samples are a recent addition to the PA API, so check if they are available

before actually using them.

- Add const to our snd_pcm_ioplug_callback_t instances

The fields are constant so let's declare that they actually are.

- Don't implement our own poll handlers, we can use the default ones

As long as we have only a single fd to watch we can use the default poll

handler implementations. So let's do this.

- Remove our own poll handler implementation entirely

Neither pcm_pulse.c nor ctl_pulse.c is using our poll handler implementation

anymore, so let's get rid of the common parts previously used by them, too

- A bag of clean-ups for pcm_ctl.c

Use more error checking where appropriate, optimize a few things, split common

code into seperate functions.

- sound: make OSS sound core optional

sound/sound_core.c implements soundcore.ko and contains two parts -

sound_class which is shared by both ALSA and OSS and device

redirection support for OSS. It's always compiled when any sound

support is enabled although it's necessary only when OSS (the actual

one or emulation) is enabled. This is slightly wasteful and as device

redirection always registers character device region for major 14, it

prevents alternative implementation.

This patch introduces a new config SOUND_OSS_CORE which is selected

iff OSS support is actually necessary and build the OSS core part

conditionally.

If OSS is disabled, soundcore merely contains sound_class but leaving

it that way seems to be the simplest approach as otherwise sound_class

should be in ALSA core file if OSS is disabled but should be in

soundcore if OSS is enabled. Also, there's also the user confusion

factor.

This patch makes CONFIG_AC97_BUS independent.

- ALSA: Allocate larger pages in sgbuf

Most hardwares have limited buffer-descriptor table length. This

also restricts the max buffer size of the sound driver.

For example, snd-hda-intel has 1MB buffer size limit, and this is

because it can have at most 256 BDL entries. For supporting larger

buffers, we need to allocate larger pages even for sg-buffers.

This patch changes the sgbuf allocation code to try to allocate

larger pages first. At each head of the allocated pages, the

number of allocated pages is stored in the lowest bits of the

corresponding entry of the table addr field. This change isn't

visible as long as the driver uses snd_sgbuf_get_addr() helper.

Also, the patch adds a new function, snd_pcm_sgbuf_get_chunk_size().

This returns the size of the chunk on continuous pages starting at

the given position offset. If the chunk reaches to a non-continuous

page, it returns the size to the boundary.

[edit] Control Midlevel

- ALSA: use correct lock in snd_ctl_dev_disconnect()

The lock used in snd_ctl_dev_disconnect() should be card->ctl_files_rwlock

for protection of card->ctl_files entries, instead of card->controls_rwsem.
