# drm\_mm\_init\_scan\_with\_range(9)

initialize range-restricted lru scanning

## NAME

drm\_mm\_init\_scan\_with\_range - initialize range-restricted lru scanning

## SYNOPSIS

**void drm\_mm\_init\_scan\_with\_range(struct drm\_mm \*** *mm***, unsigned long** *size***, unsigned** *alignment***, unsigned long** *color***, unsigned long** *start***, unsigned long** *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.
