I don't believe the DRM drivers are holding any global kernel locks
when they do wait_for_fifo. Any locks held would be internal to DRM and
can be changed if needed.

A better solution might be to loop twenty times to pick up the very
short commands. After 20us switch to a loop that allows the kernel to
schedule. You don't want to immediately schedule since that will kill
graphics performance.
You can busy-loop just

It looks like the timeout for many Radeon DRI operations is controlled
by the dev_priv-usec_timeout value, which is copied from userspace via
ioctl in radeon_cp_init. This value can be as large as 100 MSECS!

Keep in mind that any ioctl function runs with the Big Kernel Lock held.

I think it depends on which locks you are holding, and what kind of
locks they are.

so were screwed? or should we just drop the BKL inside our ioctls? I think
the DRM locking should be good enough and if it isn't it should be made
good enough..
just in case anyone is wondering nearly all DRI stuff is

Hi,
I need to make a small change to the savage DDX in order to make the new
(not yet committed) DRI interface code work properly. Currently the
visual configs created by the server don't match the ones created by
__driUtilFillInModes. Where should I commit this change? DRI CVS is dead
and Xorg

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. I don't know what it will take to fix locking
to allow this, maybe one of the original DRM authors will pop in here
with the answer.
