From c37e22046148971a35a89931aa1f951bb99d5514 Mon Sep 17 00:00:00 2001 From: Ben Widawsky Date: Wed, 31 Jul 2013 16:59:58 -0700 Subject: [PATCH] drm/i915: Add VM to pin To verbalize it, one can say, "pin an object into the given address space." The semantics of pinning remain the same otherwise. Certain objects will always have to be bound into the global GTT. Therefore, global GTT is a special case, and keep a special interface around for it (i915_gem_obj_ggtt_pin). v2: s/i915_gem_ggtt_pin/i915_gem_obj_ggtt_pin Signed-off-by: Ben Widawsky Signed-off-by: Daniel Vetter --- drivers/gpu/drm/i915/i915_drv.h | 11 +++++++++++ drivers/gpu/drm/i915/i915_gem.c | 9 +++++---- drivers/gpu/drm/i915/i915_gem_context.c | 4 ++-- drivers/gpu/drm/i915/i915_gem_execbuffer.c | 4 +++- drivers/gpu/drm/i915/intel_overlay.c | 2 +- drivers/gpu/drm/i915/intel_pm.c | 2 +- drivers/gpu/drm/i915/intel_ringbuffer.c | 8 ++++---- 7 files changed, 27 insertions(+), 13 deletions(-) diff --git a/drivers/gpu/drm/i915/i915_drv.h b/drivers/gpu/drm/i915/i915_drv.h index 79d4fed9d066..a8b51d525f8c 100644 --- a/drivers/gpu/drm/i915/i915_drv.h +++ b/drivers/gpu/drm/i915/i915_drv.h @@ -1710,6 +1710,7 @@ struct i915_vma *i915_gem_vma_create(struct drm_i915_gem_object *obj, void i915_gem_vma_destroy(struct i915_vma *vma);
