This doesn't change any implementation details as the vma-offset-manager is nearly copied 1-to-1 from TTM. The vm_lock is moved into the offset manager so we can drop it from TTM. During lookup, we use the vma locking helpers to take a reference to the found object. In all other scenarios, locking stays the same as before. We always guarantee that drm_vma_offset_remove() is called only during destruction. Hence, helpers like drm_vma_node_offset_addr() are always safe as long as the node has a valid offset. This also drops the addr_space_offset member as it is a copy of vm_start in vma_node objects. Use the accessor functions instead. v4: - remove vm_lock - use drm_vma_offset_lock_lookup() to protect lookup (instead of vm_lock) Cc: Dave Airlie Cc: Ben Skeggs Cc: Maarten Lankhorst Cc: Martin Peres Cc: Alex Deucher Cc: Thomas Hellstrom Signed-off-by: David Herrmann Reviewed-by: Daniel Vetter Signed-off-by: Dave Airlie (cherry picked from commit 72525b3f333de54fa0c42ef87f27861e41478f1e) Signed-off-by: Darren Hart diff --git a/drivers/gpu/drm/ast/ast_main.c b/drivers/gpu/drm/ast/ast_main.c index f60fd7b..c195dc2 100644 --- a/drivers/gpu/drm/ast/ast_main.c +++ b/drivers/gpu/drm/ast/ast_main.c @@ -487,7 +487,7 @@ void ast_gem_free_object(struct drm_gem_object *obj) static inline u64 ast_bo_mmap_offset(struct ast_bo *bo) { - return bo->bo.addr_space_offset;
