So this should definitely be squashed for easier review, and if its to big the split up into different refactoring steps (where each steps keeps all the code working while slowly transforming it). I'll punt for now on this here. -Daniel > --- > drivers/gpu/drm/i915/i915_drv.h | 9 ------ > drivers/gpu/drm/i915/i915_gem.c | 31 ++++++++----------- > drivers/gpu/drm/i915/i915_gem_context.c | 8 +++-- > drivers/gpu/drm/i915/i915_gem_execbuffer.c | 29 ++++++++---------- > drivers/gpu/drm/i915/i915_gem_gtt.c | 48 ++---------------------------- > 5 files changed, 34 insertions(+), 91 deletions(-) > > diff --git a/drivers/gpu/drm/i915/i915_drv.h b/drivers/gpu/drm/i915/i915_drv.h > index 2849297..a9c3110 100644 > --- a/drivers/gpu/drm/i915/i915_drv.h > +++ b/drivers/gpu/drm/i915/i915_drv.h > @@ -1938,17 +1938,8 @@ int i915_gem_context_destroy_ioctl(struct drm_device *dev, void *data, > > /* i915_gem_gtt.c */ > void i915_gem_cleanup_aliasing_ppgtt(struct drm_device *dev); > -void i915_ppgtt_bind_object(struct i915_hw_ppgtt *ppgtt, > - struct drm_i915_gem_object *obj, > - enum i915_cache_level cache_level); > -void i915_ppgtt_unbind_object(struct i915_hw_ppgtt *ppgtt, > - struct drm_i915_gem_object *obj); > - > void i915_gem_restore_gtt_mappings(struct drm_device *dev); > int __must_check i915_gem_gtt_prepare_object(struct drm_i915_gem_object *obj); > -void i915_gem_gtt_bind_object(struct drm_i915_gem_object *obj, > - enum i915_cache_level cache_level); > -void i915_gem_gtt_unbind_object(struct drm_i915_gem_object *obj); > void i915_gem_gtt_finish_object(struct drm_i915_gem_object *obj); > void i915_gem_init_global_gtt(struct drm_device *dev); > void i915_gem_setup_global_gtt(struct drm_device *dev, unsigned long start, > diff --git a/drivers/gpu/drm/i915/i915_gem.c b/drivers/gpu/drm/i915/i915_gem.c > index 24c1a91..1f35ae4 100644 > --- a/drivers/gpu/drm/i915/i915_gem.c > +++ b/drivers/gpu/drm/i915/i915_gem.c > @@ -2631,12 +2631,8 @@ int i915_vma_unbind(struct i915_vma *vma) > > trace_i915_vma_unbind(vma); > > - if (obj->has_global_gtt_mapping && i915_is_ggtt(vma->vm)) > - i915_gem_gtt_unbind_object(obj); > - if (obj->has_aliasing_ppgtt_mapping) { > - i915_ppgtt_unbind_object(dev_priv->mm.aliasing_ppgtt, obj); > - obj->has_aliasing_ppgtt_mapping = 0; > - } > + vma->vm->unbind_vma(vma); > + > i915_gem_gtt_finish_object(obj); > i915_gem_object_unpin_pages(obj); > > @@ -3354,7 +3350,6 @@ int i915_gem_object_set_cache_level(struct drm_i915_gem_object *obj, > enum i915_cache_level cache_level) > { > struct drm_device *dev = obj->base.dev; > - drm_i915_private_t *dev_priv = dev->dev_private; > struct i915_vma *vma; > int ret; > > @@ -3393,11 +3388,8 @@ int i915_gem_object_set_cache_level(struct drm_i915_gem_object *obj, > return ret; > } > > - if (obj->has_global_gtt_mapping) > - i915_gem_gtt_bind_object(obj, cache_level); > - if (obj->has_aliasing_ppgtt_mapping) > - i915_ppgtt_bind_object(dev_priv->mm.aliasing_ppgtt, > - obj, cache_level); > + list_for_each_entry(vma, &obj->vma_list, vma_link) > + vma->vm->bind_vma(vma, cache_level, 0); > } > > if (cache_level == I915_CACHE_NONE) { > @@ -3676,6 +3668,7 @@ i915_gem_object_pin(struct drm_i915_gem_object *obj, > bool map_and_fenceable, > bool nonblocking) > { > + const u32 flags = map_and_fenceable ?

Building on the last patch which created the new function pointers in the VM for bind/unbind, here we actually put those new function pointers to use. Split out as a separate patch to aid in review. I'm fine with squashing into the previous patch if people request it. v2: Updated to address the smart ggtt which can do aliasing as needed Make sure we bind to global gtt when mappable and fenceable. I thought we could get away without this initialy, but we cannot.
