# drm\_vma\_node\_offset\_addr(9)

Return sanitized offset for user-space mmaps

## NAME

drm\_vma\_node\_offset\_addr - Return sanitized offset for user-space mmaps

## SYNOPSIS

**\_\_u64 drm\_vma\_node\_offset\_addr(struct drm\_vma\_offset\_node \*** *node***);**

## ARGUMENTS

*node*

Linked offset node

## DESCRIPTION

Same as **drm\_vma\_node\_start** but returns the address as a valid offset that can be used for user-space mappings during **mmap**. This must not be called on unlinked nodes.

## RETURNS

Offset of *node* for byte-based addressing. 0 if the node does not have an object allocated.
