[ALSA] Remove PCM sleep_min and tick

2008-01-31T16:29:47Z

The 'tick' in PCM is set (again) via sw_params. And, nobody uses this feature at all except for a command line option of aplay. (This is literally 'nobody', as I checked alsa-lib API calls in all programs in major distros.) Above all, if we need finer wake-ups for the position update, it's basically an issue that the driver should solve, not tuned by each application.

[ALSA] Remove PCM xfer_align sw params

2008-01-31T16:29:47Z

The xfer_align sw_params parameter has never been used in a sane manner, and no one understands what this does exactly. The current implementation looks also buggy because it allows write of shorter size than xfer_align. So, if you do partial writes, the write isn't actually aligned at all. Removing this parameter will make some pcm_lib_* code more readable (and less buggy). Signed-off-by: Takashi Iwai Signed-off-by: Jaroslav Kysela

[ALSA] Use posix clock monotonic for PCM and timer timestamps

2008-01-31T16:29:31Z

We need an accurate and continuous (monotonic) time sources to do accurate synchronization among more timing sources. This patch allows to enable monotonic timestamps for ALSA PCM devices and enables monotonic timestamps for ALSA timer devices. Signed-off-by: Jaroslav Kysela

[ALSA] Kill useless volatile in pcm.h

2007-10-16T14:49:28Z

The volatile prefix is just useless there. Let's kill them, and then gcc will be happier, too. sound/acore/pcm.c:867: warning: passing argument 1 of ‘__constant_c_and_count_memset’ discards qualifiers from pointer target type Signed-off-by: Takashi Iwai Signed-off-by: Jaroslav Kysela

[ALSA] Fix 'discards qualifiers' compile warnings in pcm.h

2007-10-16T14:49:27Z

Fixed cast messes in pcm.h. include/sound/pcm.h: In function ‘hw_param_interval_c’: include/sound/pcm.h:800: warning: passing argument 1 of ‘hw_param_interval’ discards qualifiers from pointer target type Simply redefine the inline functions again for const pointers.

[ALSA] pcm: add snd_pcm_rate_to_rate_bit() helper

2007-10-16T13:58:54Z

Add a snd_pcm_rate_to_rate_bit() function to factor out common code used by several drivers. Signed-off-by: Clemens Ladisch Signed-off-by: Jaroslav Kysela

[ALSA] pcm: merge rates[] from pcm_misc.c and pcm_native.c

2007-10-16T13:58:53Z

Merge the rates[] arrays from pcm_misc.c and pcm_native.c because they are both the same. Signed-off-by: Clemens Ladisch Signed-off-by: Jaroslav Kysela

[ALSA] Add snd_pcm_group_for_each_entry() for code cleanup

2007-05-11T14:55:42Z

Added a new macro snd_pcm_group_for_each_entry() just for code cleanup. Old macros, snd_pcm_group_for_each() and snd_pcm_group_substream_entry(), are removed. Signed-off-by: Takashi Iwai Signed-off-by: Jaroslav Kysela

[PATCH] mark struct file_operations const 1

2007-02-12T17:48:44Z

Many struct file_operations in the kernel can be "const". Marking them const moves these to the .rodata section, which avoids false sharing with potential dirty data. In addition it'll catch accidental writes at compile time to these shared resources. Signed-off-by: Arjan van de Ven Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
