Introduce a new mem_flags member to hold these and make sure checks for these flags being set are either done under the object lock or with pages properly pinned. The flags will change during migration under the object lock. Signed-off-by: Thomas Hellström Reviewed-by: Matthew Auld --- v2: - Unconditionally set VM_IO on our VMAs in line with the rest core gem and TTM. Since the bo might be migrated while the VMA is still alive, there is no sense, whether or not it maps iomem might change. v6: - Introduce a __i915_gem_object_is_lmem() to be used in situations where we know that a fence that can't currently signal keeps the object from being migrated or evicted. - Move a couple of shmem warnings for DGFX to a later patch where we actually move system memory to TTM. v10: - Add some comments around the gem object "mem_flags" field, and use a full unsigned int for it. (Suggested by Daniel Vetter). - Add an object locked section while checking mem_flags in the live mman selftest. --- drivers/gpu/drm/i915/gem/i915_gem_internal.c | 4 +- drivers/gpu/drm/i915/gem/i915_gem_lmem.c | 22 +++++++++++ drivers/gpu/drm/i915/gem/i915_gem_lmem.h | 2 + drivers/gpu/drm/i915/gem/i915_gem_mman.c | 12 +++--- drivers/gpu/drm/i915/gem/i915_gem_object.c | 38 +++++++++++++++++++ drivers/gpu/drm/i915/gem/i915_gem_object.h | 14 ++----- .../gpu/drm/i915/gem/i915_gem_object_types.h | 27 ++++++++----- drivers/gpu/drm/i915/gem/i915_gem_pages.c | 2 +- drivers/gpu/drm/i915/gem/i915_gem_phys.c | 2 +- drivers/gpu/drm/i915/gem/i915_gem_shmem.c | 7 ++-- drivers/gpu/drm/i915/gem/i915_gem_ttm.c | 2 +- drivers/gpu/drm/i915/gem/i915_gem_userptr.c | 4 +- .../drm/i915/gem/selftests/huge_gem_object.c | 4 +- .../gpu/drm/i915/gem/selftests/huge_pages.c | 5 +-- .../drm/i915/gem/selftests/i915_gem_mman.c | 25 ++++++++---- .../drm/i915/gem/selftests/i915_gem_phys.c | 3 +- drivers/gpu/drm/i915/i915_gpu_error.c | 2 +- 17 files changed, 123 insertions(+), 52 deletions(-) diff --git a/drivers/gpu/drm/i915/gem/i915_gem_internal.c b/drivers/gpu/drm/i915/gem/i915_gem_internal.c index ce6b664b10aa..13b217f75055 100644 --- a/drivers/gpu/drm/i915/gem/i915_gem_internal.c +++ b/drivers/gpu/drm/i915/gem/i915_gem_internal.c @@ -177,8 +177,8 @@ i915_gem_object_create_internal(struct drm_i915_private *i915, return ERR_PTR(-ENOMEM); drm_gem_private_object_init(&i915->drm, &obj->base, size); - i915_gem_object_init(obj, &i915_gem_object_internal_ops, &lock_class, - I915_BO_ALLOC_STRUCT_PAGE); + i915_gem_object_init(obj, &i915_gem_object_internal_ops, &lock_class, 0); + obj->mem_flags |= I915_BO_FLAG_STRUCT_PAGE; /* * Mark the object as volatile, such that the pages are marked as diff --git a/drivers/gpu/drm/i915/gem/i915_gem_lmem.c b/drivers/gpu/drm/i915/gem/i915_gem_lmem.c index d539dffa1554..41d5182cd367 100644 --- a/drivers/gpu/drm/i915/gem/i915_gem_lmem.c +++ b/drivers/gpu/drm/i915/gem/i915_gem_lmem.c @@ -71,6 +71,28 @@ bool i915_gem_object_is_lmem(struct drm_i915_gem_object *obj) mr->type == INTEL_MEMORY_STOLEN_LOCAL); } +/** + * __i915_gem_object_is_lmem - Whether the object is resident in + * lmem while in the fence signaling critical path. + * @obj: The object to check. + * + * This function is intended to be called from within the fence signaling + * path where the fence keeps the object from being migrated.
