From bbf0c6b3620b3872929ef7d3c392ce436889110f Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Sun, 5 Dec 2010 11:30:40 +0100 Subject: drm/i915: announce to userspace that the bsd ring is coherent Otherwise we can't really fix the abi-braindeadness of forcing libva to manually wait for rendering when switching rings. Which in turn makes implementing hw semaphores a pointless exercise (at least for ironlake). [Also added the relaxed fencing param to explain the jump in numbering - relaxed fencing is in -next.] Signed-off-by: Daniel Vetter Signed-off-by: Chris Wilson --- include/drm/i915_drm.h | 2 ++ 1 file changed, 2 insertions(+) (limited to 'include/drm') diff --git a/include/drm/i915_drm.h b/include/drm/i915_drm.h index 8c641bed9bbd..a2776e2807a4 100644 --- a/include/drm/i915_drm.h +++ b/include/drm/i915_drm.h @@ -287,6 +287,8 @@ typedef struct drm_i915_irq_wait { #define I915_PARAM_HAS_EXECBUF2 9 #define I915_PARAM_HAS_BSD 10 #define I915_PARAM_HAS_BLT 11 +#define I915_PARAM_HAS_RELAXED_FENCING 12 +#define I915_PARAM_HAS_COHERENT_RINGS 13 typedef struct drm_i915_getparam { int param; -- cgit v1.2.2
