drm_vma_node_start — Return start address for page-based addressing
unsigned long drm_vma_node_start ( | struct drm_vma_offset_node * node); |
Return the start address of the given node. This can be used as offset into
the linear VM space that is provided by the VMA offset manager. Note that
this can only be used for page-based addressing. If you need a proper offset
for user-space mappings, you must apply “<< PAGE_SHIFT” or use the
drm_vma_node_offset_addr helper instead.
