2008-12-18ALSA: hda - Convert from takslet_hi_schedule() to tasklet_schedule()Takashi Iwai
Replace all tasklet_hi_schedule() callers with the normal tasklet_schedule(). The former often causes troubles with RT-kernels, and has actually no merit. Signed-off-by: Takashi Iwai <tiwai@suse.de>

2008-11-26ALSA: pcsp - Fix starting the stream with HRTIMER_CB_IRQSAFE_UNLOCKTakashi Iwai
With the callback mode HRTIMER_CB_IRQSAFE_UNLOCK, the start of the stream with zero delay doesn't work. Since IRQSAFE mode is removed, we have to change the pcsp start-up code. This patch splits the callback function to two parts, the triggering of the port and the calculation of the expire time, and the update of the ALSA PCM core. The first part is called both from the trigger-start and the hrtimer callback while the latter is handled only in the hrtimer callback. Signed-off-by: Takashi Iwai <tiwai@suse.de>

2008-11-25hrtimer: removing all ur callback modesPeter Zijlstra
Impact: cleanup, move all hrtimer processing into hardirq context This is an attempt at removing some of the hrtimer complexity by reducing the number of callback modes to 1. This means that all hrtimer callback functions will be ran from HARD-irq context. I went through all the 30 odd hrtimer callback functions in the kernel and saw only one that I'm not quite sure of, which is the one in net/can/bcm.c - hence I'm CC-ing the folks responsible for that code. Furthermore, the hrtimer core now calls callbacks directly with IRQs disabled in case you try to enqueue an expired timer. If this timer is a periodic timer (which should use hrtimer_forward() to advance its time) then it might be possible to end up in an inf. recursive loop due to the fact that hrtimer_forward() doesn't round up to the next timer granularity, and therefore keeps on calling the callback - obviously this needs a fix. Aside from that, this seems to compile and actually boot on my dual core test box - although I'm sure there are some bugs in, me not hitting any makes me certain :-) Signed-off-by: Peter Zijlstra <a.p.zijlstra@chello.nl> Signed-off-by: Ingo Molnar <mingo@elte.hu>

2008-10-20ALSA: pcsp - Fix locking messes in snd-pcspTakashi Iwai
snd-pcsp driver takes chip->substream_lock together with PCM substream lock. These are even mixed up with hrtimer's lock, resulting in messy lock depencies. Right now, snd-pcsp driver resolves the deadlock by using HRTIMER_CB_SOFTIRQ. However, this isn't nice for a really fast path like bit-flipping. This patch introduces a tasklet for PCM period handling so that the hrtimer callback can be handled fast. This also reduce the use of chip->substream_lock to avoid deadlocks. It's still used in pointer callback, but even this could be removed with a proper barrier. Another good solution is to introduce async trigger callback. But, this will involve with a major rewrite of the PCM core code, so I take first this easy fix. Signed-off-by: Takashi Iwai <tiwai@suse.de>

Fix a const pointer usage warning in the Digigram VX soundcard driver. A const pointer is being passed to copy_from_user() to load the firmware into. This is okay in this case because the function has allocated the firmware struct itself, but the const qualifier will be part of the firmware struct - so the patch casts the const away.
