drm_mm_reserve_node — insert an pre-initialized node
int drm_mm_reserve_node ( | struct drm_mm * mm, |
struct drm_mm_node * node); |
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. This is useful to initialize the allocator with preallocated objects which must be set-up before the range allocator can be set-up, e.g. when taking over a firmware framebuffer.
