From 637efacf8fcf112a188dd005c816e2b0f39894f0 Mon Sep 17 00:00:00 2001 From: Ben Widawsky Date: Mon, 5 Aug 2013 09:46:44 -0700 Subject: [PATCH] drm/i915: eliminate dead domain clearing on reset The code itself is no longer accurate without updating once we have multiple address space since clearing the domains of every object requires scanning the inactive list for all VMs. "This code is dead. 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 --- drivers/gpu/drm/i915/i915_gem.c | 8 -------- 1 file changed, 8 deletions(-) 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); } -- 2.34.1
