Name

drm_mm_init_scan_with_range — initialize range-restricted lru scanning

Synopsis

`void drm_mm_init_scan_with_range (`	struct drm_mm * `mm`,
	u64 `size`,
	unsigned `alignment`,
	unsigned long `color`,
	u64 `start`,
	u64 `end)`;

Arguments

mm: drm_mm to scan
size: size of the allocation
alignment: alignment of the allocation
color: opaque tag value to use for the allocation
start: start of the allowed range for the allocation
end: end of the allowed range for the allocation

Description

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.

Warning

As long as the scan list is non-empty, no other operations than adding/removing nodes to/from the scan list are allowed.
