Name

drm_mm_reserve_node — insert an pre-initialized node

Synopsis

int drm_mm_reserve_node (struct drm_mm * mm,
 struct drm_mm_node * node);
 

Arguments

mm

drm_mm allocator to insert node into

node

Description

This functions inserts an already set-up drm_mm_node into the allocator, meaning that start, size and color must be set by the caller.
