Detailed Description

DOC: PowerVR IOCTL GET_BO_MMAP_OFFSET interface struct drm_pvr_ioctl_get_bo_mmap_offset_args - Arguments for DRM_IOCTL_PVR_GET_BO_MMAP_OFFSET

Like other DRM drivers, the "mmap" IOCTL doesn't actually map any memory. Instead, it allocates a fake offset which refers to the specified buffer object. This offset can be used with a real mmap call on the DRM device itself.
