Just remove it rather than port it to vma." - Chris Wilson Recommended-by: Chris Wilson Signed-off-by: Ben Widawsky Signed-off-by: Daniel Vetter --- diff --git a/drivers/gpu/drm/i915/i915_gem.c b/drivers/gpu/drm/i915/i915_gem.c index b7386df82030..3debb35b7195 100644 --- a/drivers/gpu/drm/i915/i915_gem.c +++ b/drivers/gpu/drm/i915/i915_gem.c @@ -2291,20 +2291,12 @@ void i915_gem_restore_fences(struct drm_device *dev) void i915_gem_reset(struct drm_device *dev) { struct drm_i915_private *dev_priv = dev->dev_private; - struct i915_address_space *vm = &dev_priv->gtt.base; - struct drm_i915_gem_object *obj; struct intel_ring_buffer *ring; int i; for_each_ring(ring, dev_priv, i) i915_gem_reset_ring_lists(dev_priv, ring); - /* Move everything out of the GPU domains to ensure we do any - * necessary invalidation upon reuse. - */ - list_for_each_entry(obj, &vm->inactive_list, mm_list) - obj->base.read_domains &= ~I915_GEM_GPU_DOMAINS; - i915_gem_restore_fences(dev); }
