	1. Currrently, scheduler is triggered by delay_work, it's only can be
	   accurate at 10ms level, so have to change the scheduler period to
	   10ms, it will have stability impact.
	2. Test two vGPU type 2 and type 5, the fps of tropic in two guest show 
  	   about 5:2, it's workable but the precision is not good.

	TODO: 1. Use htimer replace the delay_work to trigger scheduler.
	      2. Create dummy vGPU to help caculation.   

Ping Gao (5):
  drm/i915/gvt: add some statistic routine for scheduler
  drm/i915/gvt: add basic funtion for fairness control
  drm/i915/gvt: control the scheduler by timeslice usage
  drm/i915/gvt: define weight according the vGPU type
  drm/i915/gvt: set scheduler time to 10ms
