The time based scheduler poll context busy status at every micro-second during vGPU switch, it will make GPU idle for a while when the context is very small and completed before the next micro-second arrival. Trigger scheduling immediately after context complete will eliminate GPU idle and improve performance. Create two vGPU with same type, run Heaven simultaneously: Before this patch: +---------+----------+----------+ | | vGPU1 | vGPU2 | +---------+----------+----------+ | Heaven | 357 | 354 | +-------------------------------+ After this patch: +---------+----------+----------+ | | vGPU1 | vGPU2 | +---------+----------+----------+ | Heaven | 397 | 398 | +-------------------------------+ v2: Let need_reschedule protect by gvt-lock.
