NAME¶
drm_vma_node_start - Return start address for page-based addressingSYNOPSIS¶
unsigned long
drm_vma_node_start(struct drm_vma_offset_node * node);
ARGUMENTS¶
nodeNode to inspect
DESCRIPTION¶
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.RETURNS¶
Start address of node for page-based addressing. 0 if the node does not have an offset allocated.AUTHORS¶
