Changbin Du	c130456cef	drm/i915/gvt: Kick scheduler when new workload queued ... The current schedule policy rely on a 1ms timer to execute workload. This can introduce maximum 1ms unnecessary latency. This is especially bad for small media workloads. And I don't think we need this timer for QoS, but the change is not simply remove the code. So I made a new API intel_gvt_kick_schedule() for future change. Signed-off-by: Changbin Du <changbin.du@intel.com> Signed-off-by: Zhenyu Wang <zhenyuw@linux.intel.com>	2017-12-04 11:24:35 +08:00
Ping Gao	91d0101ad3	drm/i915/gvt: use hrtimer replace delayed_work in scheduler ... Currently the scheduler is triggered by delayed_work, which doesn't provide precision at microsecond level. Move to hrtimer instead for more accurate control.
