[RFC PATCH v3 3/4] ipvr: user mode helper for ipvr drm driver
Yao Cheng
yao.cheng at intel.com
Fri Nov 21 11:09:08 PST 2014
add usermode helper for the ipvr kernel driver.
test_ioctl: test kernel driver by directly ioctl
v2:
take Emil's comments
- correctly align ipvr_drm.h
v3:
take Daniel Vetter and Daniel Stone's comments, and implement PRIME
- correctly align ipvr_drm.h
- use __u32 family in ipvr_drm.h
- rip out explicit fence from libdrm_ipvr
- implemented PRIME support
- add relocation fixup implementation
