We first add the notion of objects being migratable under the object lock to i915 gem, and add some asserts to verify that objects are either locked or pinned when the placement is checked by the gem code. Patch 2 and 3 deals with updating the i915 gem bookkeeping after a TTM move, Patch 4 moves system over from shmem to TTM for discrete Note that the mock device doesn't consider itself discrete so the TTM system path is not checked by the mock selftests. v2: - Style fixes (reported by Matthew Auld) - Drop the last patch (migration) It needs selftests and some additional work. - Unconditionally add VM_IO at mmap time. v3: - More style fixes (reported by Matthew Auld) - Don't overfill the busy placement vector (reported by Mattew Auld) Thomas Hellström (4): drm/i915: Update object placement flags to be mutable drm/i915/ttm: Adjust gem flags and caching settings after a move drm/i915/ttm: Calculate the object placement at get_pages time drm/i915/ttm: Use TTM for system memory drivers/gpu/drm/i915/gem/i915_gem_internal.c | 4 +- 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 | 20 +- 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 | 10 +- drivers/gpu/drm/i915/gem/i915_gem_ttm.c | 225 ++++++++++++++---- 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 | 4 +- .../drm/i915/gem/selftests/i915_gem_phys.c | 3 +- drivers/gpu/drm/i915/i915_drv.h | 3 - drivers/gpu/drm/i915/intel_memory_region.c | 7 +- drivers/gpu/drm/i915/intel_memory_region.h | 8 + drivers/gpu/drm/i915/intel_region_ttm.c | 8 +- drivers/gpu/drm/i915/intel_region_ttm.h | 2 + 19 files changed, 279 insertions(+), 96 deletions(-)
