Initialize lru scanning
void drm_mm_init_scan(struct drm_mm * mm, unsigned long size, unsigned alignment, unsigned long color);
mm
drm_mm to scan
size
size of the allocation
alignment
alignment of the allocation
color
opaque tag value to use for the allocation
This simply sets up the scanning routines with the parameters for the desired hole. Note that there's no need to specify allocation flags, since they only change the place a node is allocated from within a suitable hole.
As long as the scan list is non-empty, no other operations than adding/removing nodes to/from the scan list are allowed.
