[PATCH v7 1/3] drm/i915: Update object placement flags to be mutable

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The object ops i915_GEM_OBJECT_HAS_IOMEM and the object
I915_BO_ALLOC_STRUCT_PAGE flags are considered immutable by
much of our code. 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.

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.
