I was about to suggest this before patch 2/3 to make it simpler. For historical context: https://patchwork.kernel.org/patch/9135411/ I would amend the commit message a little. 'We're no longer using' suggests that we changed recently/by earlier commits how we map into the invalid ptes. I think it has always been the case that we map to valid==scratch. Lets try to distill the reasoning from Chris Wilson's reply for future reader, something like: 'We never used any invalid ptes, as those were put in place for a possibility of doing gpu faults. However our batchbuffers are not restricted in length, so everything needs to be pointing to something and thus out-of-bounds pointing to scratch. Remove the valid flag as it is always true.' That message conveyed with perhaps better wording/english, and you can add my, Reviewed-by: Mika Kuoppala <mika.kuopp...@intel.com> -Mika > Cc: Chris Wilson <ch...@chris-wilson.co.uk> > Cc: Joonas Lahtinen <joonas.lahti...@linux.intel.com> > Cc: Michel Thierry <michel.thie...@intel.com> > Cc: Mika Kuoppala <mika.kuopp...@intel.com> > Signed-off-by: Michał Winiarski <michal.winiar...@intel.com> > --- > drivers/gpu/drm/i915/i915_gem.c | 6 +- > drivers/gpu/drm/i915/i915_gem_execbuffer.c | 3 +- > drivers/gpu/drm/i915/i915_gem_gtt.c | 154 > +++++++++++------------------ > drivers/gpu/drm/i915/i915_gem_gtt.h | 5 +- > 4 files changed, 65 insertions(+), 103 deletions(-) > > diff --git a/drivers/gpu/drm/i915/i915_gem.c b/drivers/gpu/drm/i915/i915_gem.c > index 1418c1c..b344340 100644 > --- a/drivers/gpu/drm/i915/i915_gem.c > +++ b/drivers/gpu/drm/i915/i915_gem.c > @@ -919,8 +919,7 @@ out_unpin: > if (node.allocated) { > wmb(); > ggtt->base.clear_range(&ggtt->base, > - node.start, node.size, > - true); > + node.start, node.size); > i915_gem_object_unpin_pages(obj); > remove_mappable_node(&node); > } else { > @@ -1228,8 +1227,7 @@ out_unpin: > if (node.allocated) { > wmb(); > ggtt->base.clear_range(&ggtt->base, > - node.start, node.size, > - true); > + node.start, node.size); > i915_gem_object_unpin_pages(obj); > remove_mappable_node(&node); > } else { > diff --git a/drivers/gpu/drm/i915/i915_gem_execbuffer.c > b/drivers/gpu/drm/i915/i915_gem_execbuffer.c > index 33c8522..54b091b 100644 > --- a/drivers/gpu/drm/i915/i915_gem_execbuffer.c > +++ b/drivers/gpu/drm/i915/i915_gem_execbuffer.c > @@ -370,8 +370,7 @@ static void reloc_cache_fini(struct reloc_cache *cache) > > ggtt->base.clear_range(&ggtt->base, > cache->node.start, > - cache->node.size, > - true); > + cache->node.size); > drm_mm_remove_node(&cache->node); > } else { > i915_vma_unpin((struct i915_vma *)cache->node.mm); > diff --git a/drivers/gpu/drm/i915/i915_gem_gtt.c > b/drivers/gpu/drm/i915/i915_gem_gtt.c > index 281e349..fa78bb1 100644 > --- a/drivers/gpu/drm/i915/i915_gem_gtt.c > +++ b/drivers/gpu/drm/i915/i915_gem_gtt.c > @@ -191,15 +191,13 @@ static void ppgtt_unbind_vma(struct i915_vma *vma) > { > vma->vm->clear_range(vma->vm, > vma->node.start, > - vma->size, > - true); > + vma->size); > } > > static gen8_pte_t gen8_pte_encode(dma_addr_t addr, > - enum i915_cache_level level, > - bool valid) > + enum i915_cache_level level) > { > - gen8_pte_t pte = valid ? _PAGE_PRESENT | _PAGE_RW : 0; > + gen8_pte_t pte = _PAGE_PRESENT | _PAGE_RW; > pte |= addr; > > switch (level) { > @@ -218,10 +216,9 @@ static gen8_pte_t gen8_pte_encode(dma_addr_t addr, > } > > static gen8_pde_t gen8_pde_encode(const dma_addr_t addr, > - const enum i915_cache_level level, > - bool valid) > + const enum i915_cache_level level) > { > - gen8_pde_t pde = valid ? _PAGE_PRESENT | _PAGE_RW : 0; > + gen8_pde_t pde = _PAGE_PRESENT | _PAGE_RW; > pde |= addr; > if (level != I915_CACHE_NONE) > pde |= PPAT_CACHED_PDE_INDEX; > @@ -235,9 +232,9 @@ static gen8_pde_t gen8_pde_encode(const dma_addr_t addr, > > static gen6_pte_t snb_pte_encode(dma_addr_t addr, > enum i915_cache_level level, > - bool valid, u32 unused) > + u32 unused) > { > - gen6_pte_t pte = valid ?
