2006-03-22[ALSA] PCM midlevel & PCM OSS - make procfs & OSS plugin code optionalJaroslav Kysela
Modules: ALSA Core,PCM Midlevel,ALSA<-OSS emulation,USB generic driver 1) The verbose procfs code for the PCM midlevel and usb audio can be removed now (more patches will follow). CONFIG_SND_VERBOSE_PROCFS 2) The PCM OSS plugin system can be also compiled optionaly. CONFIG_SND_PCM_OSS_PLUGINS Signed-off-by: Jaroslav Kysela <perex@suse.cz>
2006-01-09[PATCH] mutex subsystem, semaphore to mutex: VFS, ->i_semJes Sorensen
This patch converts the inode semaphore to a mutex. I have tested it on XFS and compiled as much as one can consider on an ia64. Anyway your luck with it might be different. Modified-by: Ingo Molnar <mingo@elte.hu> (finished the conversion) Signed-off-by: Jes Sorensen <jes@sgi.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2006-01-03[ALSA] Optimize for config without PROC_FS (seq and oss parts)Takashi Iwai
Modules: ALSA<-OSS emulation,ALSA sequencer,ALSA<-OSS sequencer Optimize the code when compiled without CONFIG_PROC_FS (in seq and oss emulation parts). Signed-off-by: Takashi Iwai <tiwai@suse.de>
2006-01-03[ALSA] dynamic minors (3/6): store device-specific object pointers dynamicallyClemens Ladisch
Instead of storing the pointers to the device-specific structures in an array, put them into the struct snd_minor, and look them up dynamically. This makes the device type modules independent of the minor number encoding. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
2006-01-03[ALSA] dynamic minors (1/6): store device type in struct snd_minorClemens Ladisch
Instead of a comment string, store the device type in the snd_minor structure. This makes snd_minor more flexible, and has the nice side effect that we don't need anymore to create a separate snd_minor template for registering a device but can pass the file_operations directly to snd_register_device(). Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
2006-01-03[ALSA] Remove xxx_t typedefs: PCM OSS-emulationTakashi Iwai

2005-11-04[ALSA] Add missing KERN_* prefixTakashi Iwai
Modules: ALSA<-OSS emulation,USB generic driver,USB USX2Y Added missing KERN_* prefix to printk. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2005-11-04[ALSA] Make snd_task_name() module localTakashi Iwai
Modules: ALSA Core,ALSA<-OSS emulation Remove a global function snd_task_name(), and move it local to snd-pcm-oss module. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2005-11-04[ALSA] Remove snd_runtime_check() macroTakashi Iwai
Remove snd_runtime_check() macro. This macro worsens the readability of codes. They should be either normal if() or removable asserts. Also, the assert displays stack-dump, instead of only the last caller pointer. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2005-09-12[ALSA] Replace with kzalloc() - core stuffTakashi Iwai
Control Midlevel,ALSA Core,HWDEP Midlevel,PCM Midlevel,RawMidi Midlevel Timer Midlevel,ALSA<-OSS emulation Replace kcalloc(1,..) with kzalloc(). Signed-off-by: Takashi Iwai <tiwai@suse.de>
2005-09-12[ALSA] pcm-oss - Add bugg-yptr optionTakashi Iwai
Documentation,ALSA<-OSS emulation Added 'buggy-ptr' proc option to switch the behavior of GETOPTR ioctl. Signed-off-by: Takashi Iwai <tiwai@suse.de>

2005-08-30[ALSA] ALSA's struct _snd_pcm_substream: Obsolete open_flagKarsten Wiese
PCM Midlevel,ALSA<-OSS emulation,USB USX2Y This patch removes open_flag from struct _snd_pcm_substream. All of its uses are substituted by querying struct _snd_pcm_substream's member ffile instead. Signed-off-by: Karsten Wiese <annabellesgarden@yahoo.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2005-06-23[PATCH] create a kstrdup library functionPaulo Marques
This patch creates a new kstrdup library function and changes the "local" implementations in several places to use this function. Most of the changes come from the sound and net subsystems. The sound part had already been acknowledged by Takashi Iwai and the net part by David S. Miller. I left UML alone for now because I would need more time to read the code carefully before making changes there.

2005-05-29[ALSA] alsa-oss - 2nd - improved readabilityJaroslav Kysela
ALSA<-OSS emulation Use 'long' for byte counters in snd_pcm_oss_bytes() snd_pcm_alsa_bytes(). Signed-off-by: Jaroslav Kysela <perex@suse.cz>
2005-05-29[ALSA] alsa-oss - improve readability of snd_pcm_oss_bytes() functionJaroslav Kysela
ALSA<-OSS emulation Added bytes variable and do not use the frames argument as a temporaly storage for the byte counter. Signed-off-by: Jaroslav Kysela <perex@suse.cz>
2005-05-29[ALSA] Reverted last patch for SNDCTL_DSP_GETOPTR fix & possible overflow fixJaroslav Kysela
ALSA<-OSS emulation This reverts the last patch which wrongly mixes bytes and frames. The real culprit might be the 32-bit overflow, so the return expression uses 64-bit values now in snd_pcm_oss_bytes(). Signed-off-by: Jaroslav Kysela <perex@suse.cz>
2005-05-29[ALSA] pcm_oss - fix SNDCTL_DSP_GETOPTR not working correctlyRoger Mach
ALSA<-OSS emulation This patch changes snd_pcm_oss_bytes() by adding a local variable for the frames -> bytes conversion, which means that the frame count is no longer corrupted by this conversion. Signed-off-by: Roger Mach <bigmach@us.ibm.com> Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
2005-05-29[ALSA] Fix capture on OSS emulationTakashi Iwai
ALSA<-OSS emulation Fix the noisy capture on some hardwares over OSS emulation. Change back to avail_min = period_size for capture direction. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2005-05-29[ALSA] kill dead codeAdrian Bunk
ALSA<-OSS emulation The Coverity checker found this obviously dead code. I'm not sure which of the if (plugin == NULL) is correct - this patch removes the one that couldn't be true. Signed-off-by: Adrian Bunk <bunk@stusta.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>
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!
