I guess I don't understand, the article said the sound(OSS) took the BKL? It didn't say that ALSA's OSS is effected, I'm assuming that it is not. In any case ALSA still uses ioctls. So no mater what sound takes the BKL and disables preemption?
I don't think that preemption could work at all, unless when the BKL is [1]droped you preemptate. I think you have something wrong, as DRI dose these things alot so it might not block preemption. 1. msleep, usercpy, ect. --- Lee Revell <[EMAIL PROTECTED]> wrote: > On Sun, 2004-08-22 at 22:09, Mike Mestnik wrote: > > --- Jon Smirl <[EMAIL PROTECTED]> wrote: > > > > > Michel pointed out that all IOCTL calls hold the big kernel lock. > > > Releasing this lock is sure to case problems since the DRM code is > not > > > designed to be reentrant.
