[Intel-gfx] [Patch 4/5] multiple ring buffer support, adapt the intel_ring_buffer with gem
Zou, Nanhai
nanhai.zou at intel.com
Wed Apr 7 08:28:36 CEST 2010
Adapt intel_ring_buffer into gem.
On which ring to run is decided on the flag of execbuffer2.
With other legacy ioctls, gem objects and requests are consider to be on
render ring by default.
