This patch series enables resource streamer for xf86-video-intel UXA. Fixes i965 Mesa driver that makes use of resource streamer optimization to survive a full piglit run without bricking the machine. Previously, I get random hungs when doing a full piglit round when enabling RS. After months of head-scratching, I noticed I didn't quite pay attention to this small detail in bspec: "The binding table generator feature has a simple all or nothing model. If HW generated binding tables are enabled, the driver must enable the pool and use 3D_HW_BINDING_TABLE_POINTER_* commands." I realized that our xf86-video-intel driver is piping out 3D commands as well that used the older manual-generated binding table format that caused a conflict when Mesa is using the hw-generated binding table format. I didn't touch the SNA and video acceleration paths yet. Please let me know if I'm on the right track.
