drm_vc4_mmap_bo Struct Reference

Public Attributes
__u32	handle
__u32	flags
__u64	offset

Detailed Description

struct drm_vc4_mmap_bo - ioctl argument for mapping VC4 BOs.

This doesn't actually perform an mmap. Instead, it returns the offset you need to use in an mmap on the DRM device node. This means that tools like valgrind end up knowing about the mapped memory.

There are currently no values for the flags argument, but it may be used in a future extension.
