2009-05-29ALSA: PCM midlevel: improve fifo_size handlingJaroslav Kysela
Move the fifo_size assignment to hw->ioctl callback to allow lowlevel drivers overwrite the default behaviour. fifo_size is in frames not bytes as specified in asound.h and alsa-lib's documentation, but most hardware have fixed byte based FIFOs. Introduce internal SNDRV_PCM_INFO_FIFO_IN_FRAMES. Signed-off-by: Jaroslav Kysela <perex@perex.cz> Signed-off-by: Takashi Iwai <tiwai@suse.de>

2009-03-26make exported headers use strict posix typesArnd Bergmann
A number of standard posix types are used in exported headers, which is not allowed if __STRICT_KERNEL_NAMES is defined. In order to get rid of the non-__STRICT_KERNEL_NAMES part and to make sane headers the default, we have to change them all to safe types. There are also still some leftovers in reiserfs_fs.h, elfcore.h and coda.h, but these files have not compiled in user space for a long time. This leaves out the various integer types ({u_,u,}int{8,16,32,64}_t), which we take care of separately.

2009-03-11ALSA: Use define for ioctl definitionsTakashi Iwai
Use define instead of enum for ioctl definitions since strace can't parse ioctls defined via enum properly. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2009-03-11ALSA: Remove obsolete snd_xferv struct and ioctlsTakashi Iwai
Removed obsleted snd_xferv struct and ioctls that are no longer used in the current codebase. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2008-10-24ALSA: Add hrtimer backend for ALSA timer interfaceTakashi Iwai
Added the hrtimer backend for ALSA timer interface. It can be used for the sequencer timer source. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2008-10-10ALSA: Increase components array sizeTakashi Iwai
Increase the card components[] (and thus snd_card_info.components[], too) array size from 80 to 128 chars so that more strings can be stored. The 80 chars aren't enough for more than 2 HD-audio codecs, and this hits an ugly snd_BUG() as reported by Wu Fegguang for HP 2230s. The control protocol number is increased to 2.0.6 as well, in case it matters.

2008-10-10ALSA: Remove bitwise from snd_pcm_hw_param_tTakashi Iwai
We have some arithmetic operations against snd_pcm_hw_param_t, thus bitwise isn't correct for it. Better to remove the flag to shut up sparse warnings. Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@perex.cz>

2008-01-31[ALSA] PCM interface - rename SNDRV_PCM_TSTAMP_MMAP to SNDRV_PCM_TSTAMP_ENABLEJaroslav Kysela
Change semantics for SNDRV_PCM_TSTAMP_MMAP. Doing timestamping only in the interrupt handler might cause that hw_ptr is not related to actual timestamp. With this change, grab timestamp at every hw_ptr update to have always valid timestamp + ring buffer position pair. With this change, SNDRV_PCM_TSTAMP_MMAP was renamed to SNDRV_PCM_TSTAMP_ENABLE. It's no regression (I think). Signed-off-by: Jaroslav Kysela <perex@perex.cz>
2008-01-31[ALSA] Remove PCM xfer_align sw paramsTakashi Iwai
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 <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@perex.cz>
2008-01-31[ALSA] Remove indirect control accessTakashi Iwai
This patch removes the indirect control access to the control elements. The indirect access has never been used and is even broken on 32bit ioctl wrapper. Let's clean it up. The pointers still remain in snd_ctl_elem_* structs just to make sure that the struct size won't change. Once after checking the size consistency, we can get rid of them, too.

2008-01-31[ALSA] Use posix clock monotonic for PCM and timer timestampsJaroslav Kysela

2005-04-16Linux-2.6.12-rc2Linus Torvalds
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
