Find node in offset space
struct drm_vma_offset_node * drm_vma_offset_lookup_locked(struct drm_vma_offset_manager * mgr, unsigned long start, unsigned long pages);
mgr
Manager object
start
Start address for object (page-based)
pages
Size of object (page-based)
Same as drm_vma_offset_lookup but requires the caller to lock offset lookup manually. See drm_vma_offset_lock_lookup for an example.
Returns NULL if no suitable node can be found. Otherwise, the best match is returned.
