It should apply to 2.6.35 as well.
Not really. The first part of the patch looks like this:
diff --git a/drivers/gpu/drm/radeon/r600.c b/drivers/gpu/drm/radeon/r600.c index 667c237..5668b90 100644 --- a/drivers/gpu/drm/radeon/r600.c +++ b/drivers/gpu/drm/radeon/r600.c @@ -3491,7 +3491,7 @@ void r600_ioctl_wait_idle(struct radeon_device *rdev, struct radeon_bo *bo) * rather than write to HDP_REG_COHERENCY_FLUSH_CNTL */ if ((rdev->family >= CHIP_RV770) && (rdev->family <= CHIP_RV740)) {
void __iomem *ptr = (void *)rdev->gart.table.vram.ptr;
void __iomem *ptr = (void *)rdev->vram_scratch.ptr;u32 tmp;
WREG32(HDP_DEBUG1, 0);
That function looks like this here though:
void r600_ioctl_wait_idle(struct radeon_device *rdev, struct radeon_bo *bo) { WREG32(R_005480_HDP_MEM_COHERENCY_FLUSH_CNTL, 0x1); }
Thus this hunk already fails to apply.
