| * ALSA: pcm - Fix hwptr buffer-size overlap bugTakashi Iwai2009-07-231-1/+1
| | | | | | | | | | | | | | | | | | The fix 79452f0a28aa5a40522c487b42a5fc423647ad98 introduced another bug due to the missing offset for the overlapped hwptr. When the hwptr goes back to zero, the delta value has to be corrected with the buffer size. Otherwise this causes looping sounds. Signed-off-by: Takashi Iwai <tiwai@suse.de>

| * ALSA: pcm - Add logging of hwptr updates and interrupt updatesTakashi Iwai2009-07-231-0/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | Added the logging functionality to xrun_debug to record the hwptr updates via snd_pcm_update_hw_ptr() and snd_pcm_update_hwptr_interrupt(), corresponding to 16 and 8, respectively. For example, # echo 9 > /proc/asound/card0/pcm0p/xrun_debug will record the position and other parameters at each period interrupt together with the normal XRUN debugging.

| * ALSA: pcm - Fix regressions with VMwareTakashi Iwai2009-07-221-1/+10
| | | | | | | | | | | | | | | | | | | | | | | | VMware tends to report PCM positions and period updates at utterly wrong timing. This screws up the recent PCM core code that tries to correct the position based on the irq timing. Now, when a backward irq position is detected, skip the update instead of rebasing. (This is almost the old behavior before 2.6.30.) Signed-off-by: Takashi Iwai <tiwai@suse.de>

This lock is needed to allow us to walk the list and check to see if our new name is a duplicate. Unfortunately this causes a lockup when called from snd_card_register() (in cases where no ID is supplied for the card) since the card list is already locked there. Fix this fairly hideously by factoring out the implementation and using a flag to indicate if the lock should be held. A better fix would probably be to refactor snd_card_register() to move the _set_id() outside the locking region but I can't immediately see anything I can convince myself is safe.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Setting ->owner as done currently (pde->owner = THIS_MODULE) is racy as correctly noted at bug #12454. Someone can lookup entry with NULL ->owner, thus not pinning enything, and release it later resulting in module refcount underflow. We can keep ->owner and supply it at registration time like ->proc_fops and ->data. But this leaves ->owner as easy-manipulative field (just one C assignment) and somebody will forget to unpin previous/pin current module when switching ->owner. ->proc_fops is declared as "const" which should give some thoughts. ->read_proc/->write_proc were just fixed to not require ->owner for protection. rmmod'ed directories will be empty and return "." and ".." -- no harm. And directories with tricky enough readdir and lookup shouldn't be modular. We definitely don't want such modular code. Removing ->owner will also make PDE smaller. So, let's nuke it. Kudos to Jeff Layton for reminding about this, let's say, oversight. http://bugzilla.kernel.org/show_bug.cgi?id=12454 Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com>
