From 13c2ceb6addb6b14468e09b75832c98909eed8e7 Mon Sep 17 00:00:00 2001 From: Matthew Auld Date: Wed, 16 Jun 2021 16:25:01 +0100 Subject: [PATCH] drm/i915/ttm: restore min_page_size behaviour MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit We now have bo->page_alignment which perfectly describes what we need if we have min page size restrictions for lmem. We can also drop the flag here, since this is the default behaviour for all objects. v2(Thomas): - bo->page_alignment is in page units Signed-off-by: Matthew Auld Cc: Thomas Hellström Reviewed-by: Thomas Hellström Link: https://patchwork.freedesktop.org/patch/msgid/20210616152501.394518-7-matthew.auld@intel.com --- drivers/gpu/drm/i915/gem/i915_gem_ttm.c | 4 ++-- drivers/gpu/drm/i915/intel_memory_region.h | 3 +-- drivers/gpu/drm/i915/intel_region_ttm.c | 2 +- drivers/gpu/drm/i915/selftests/mock_region.c | 2 +- 4 files changed, 5 insertions(+), 6 deletions(-) diff --git a/drivers/gpu/drm/i915/gem/i915_gem_ttm.c b/drivers/gpu/drm/i915/gem/i915_gem_ttm.c index b8739f3d34623..9366b18d1bc6f 100644 --- a/drivers/gpu/drm/i915/gem/i915_gem_ttm.c +++ b/drivers/gpu/drm/i915/gem/i915_gem_ttm.c @@ -672,9 +672,9 @@ int __i915_gem_ttm_object_init(struct intel_memory_region *mem, */ obj->base.vma_node.driver_private = i915_gem_to_ttm(obj); ret = ttm_bo_init(&i915->bdev, i915_gem_to_ttm(obj), size, - bo_type, &i915_sys_placement, 1, + bo_type, &i915_sys_placement, + mem->min_page_size >> PAGE_SHIFT, true, NULL, NULL, i915_ttm_bo_destroy); - if (!ret) obj->ttm.created = true; diff --git a/drivers/gpu/drm/i915/intel_memory_region.h b/drivers/gpu/drm/i915/intel_memory_region.h index b04fb22726d9d..2be8433d373ac 100644 --- a/drivers/gpu/drm/i915/intel_memory_region.h +++ b/drivers/gpu/drm/i915/intel_memory_region.h @@ -40,8 +40,7 @@ enum intel_region_id { #define REGION_STOLEN_SMEM BIT(INTEL_REGION_STOLEN_SMEM) #define REGION_STOLEN_LMEM BIT(INTEL_REGION_STOLEN_LMEM) -#define I915_ALLOC_MIN_PAGE_SIZE BIT(0) -#define I915_ALLOC_CONTIGUOUS BIT(1) +#define I915_ALLOC_CONTIGUOUS BIT(0) #define for_each_memory_region(mr, i915, id) \ for (id = 0; id < ARRAY_SIZE((i915)->mm.regions); id++) \ diff --git a/drivers/gpu/drm/i915/intel_region_ttm.c b/drivers/gpu/drm/i915/intel_region_ttm.c index 052253c81e984..d53d78dec2bec 100644 --- a/drivers/gpu/drm/i915/intel_region_ttm.c +++ b/drivers/gpu/drm/i915/intel_region_ttm.c @@ -167,7 +167,7 @@ intel_region_ttm_resource_alloc(struct intel_memory_region *mem, int ret; mock_bo.base.size = size; - mock_bo.page_alignment = 1; + mock_bo.page_alignment = mem->min_page_size >> PAGE_SHIFT; place.flags = flags; ret = man->func->alloc(man, &mock_bo, &place, &res); diff --git a/drivers/gpu/drm/i915/selftests/mock_region.c b/drivers/gpu/drm/i915/selftests/mock_region.c index 3b3264311c910..fa786dede6080 100644 --- a/drivers/gpu/drm/i915/selftests/mock_region.c +++ b/drivers/gpu/drm/i915/selftests/mock_region.c @@ -28,7 +28,7 @@ static int mock_region_get_pages(struct drm_i915_gem_object *obj) struct sg_table *pages; int err; - flags = I915_ALLOC_MIN_PAGE_SIZE; + flags = 0; if (obj->flags & I915_BO_ALLOC_CONTIGUOUS) flags |= TTM_PL_FLAG_CONTIGUOUS; -- 2.39.5
