drm_vma_offset_manager_init9
Initialize new offset-manager
Arguments
mgr
Manager object
page_offset
Offset of available memory area (page-based)
size
Size of available address space range (page-based)
Overview
Initialize a new offset-manager. The offset and area size available for the manager are given as page_offset and size. Both are interpreted as page-numbers, not bytes.
Adding/removing nodes from the manager is locked internally and protected against concurrent access. However, node allocation and destruction is left for the caller. While calling into the vma-manager, a given node must always be guaranteed to be referenced.
