[Intel-gfx] [PATCH 5/5] drm/i915:Use the coarse mechanism based on drm fd to dispatch the BSD command on BDW GT3

2014-04-08 Thread Zhao Yakui
The BDW GT3 has two independent BSD rings, which can be used to process the video commands. To be simpler, it is transparent to user-space driver/middleware. Instead the kernel driver will decide which ring is to dispatch the BSD video command. As every BSD ring is powerful, it is enough to dispa
