2010-01-07	gpu/drm/radeon/radeon_irq.c: move a dereference below a NULL test	Darren Jenkins	1	-5/+5
	If a NULL value is possible, the dereference should only occur after the NULL test. Coverity CID: 13338 Signed-off-by: Darren Jenkins <darrenrjenkins@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
2009-09-18	drm/radeon/r600: don't do interrupts	Alex Deucher	1	-0/+18
	Interrupts are not supported yet. This prevents things like mesa from trying to use them. Signed-off-by: Alex Deucher <alexdeucher@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
2009-03-13	drm/radeon: RS600: fix interrupt handling	Alex Deucher	1	-7/+7
	the checks weren't updated when RS600 support was added. Signed-off-by: Alex Deucher <alexdeucher@gmail.com> Signed-off-by: Dave Airlie <airlied@linux.ie>
2008-12-23	drm/radeon: fix correctness of irq_enabled check for radeon.	Dave Airlie	1	-2/+2
	This check was introduced with the logic the wrong way around. Fixes regression: http://bugzilla.kernel.org/show_bug.cgi?id=12216 Tested-by: François Valenduc <francois.valenduc@tvcablenet.be> Signed-off-by: Dave Airlie <airlied@redhat.com>
2008-12-09	drm/radeon: don't actually enable the IRQ regs until irq is enabled	Dave Airlie	1	-4/+4
	vblank can try and enable the IRQ registers before we've set the interrupt handler up. Signed-off-by: Dave Airlie <airlied@redhat.com>
2008-11-25	drm: move drm vblank initialization/cleanup to driver load/unload	Keith Packard	1	-5/+0
	drm vblank initialization keeps track of the changes in driver-supplied frame counts across vt switch and mode setting, but only if you let it by not tearing down the drm vblank structure. Signed-off-by: Keith Packard <keithp@keithp.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
2008-10-18	drm: Rework vblank-wait handling to allow interrupt reduction.	Jesse Barnes	1	-100/+168
	Previously, drivers supporting vblank interrupt waits would run the interrupt all the time, or all the time that any 3d client was running, preventing the CPU from sleeping for long when the system was otherwise idle. Now, interrupts are disabled any time that no client is waiting on a vblank event. The new method uses vblank counters on the chipsets when the interrupts are turned off, rather than counting interrupts, so that we can continue to present accurate vblank numbers.

2008-07-14	drm: reorganise drm tree to be more future proof.	Dave Airlie	1	-0/+320
	With the coming of kernel based modesetting and the memory manager stuff, the everything in one directory approach was getting very ugly and starting to be unmanageable. This restructures the drm along the lines of other kernel components. It creates a drivers/gpu/drm directory and moves the hw drivers into subdirectores. It moves the includes into an include/drm, and sets up the unifdef for the userspace headers we should be exporting. Signed-off-by: Dave Airlie <airlied@redhat.com>
