Renaming: The helper function res_to_mem_region is now xe_map_resource_to_region. Abstraction: The patch removes instances where block->private was accessed directly to obtain VRAM region data allowing VRAM manager to own block->private for future use cases. V2(MattB): Add more detail about patch also adjust variable placement Reviewed-by: Matthew Brost <matthew.brost@intel.com> Link: https://patch.msgid.link/20260407055107.2782450-2-tejas.upadhyay@intel.com Signed-off-by: Tejas Upadhyay <tejas.upadhyay@intel.com>
