From a199baede7e59fd0b303c50d4a25fc0ee7c290d9 Mon Sep 17 00:00:00 2001 From: David Li Date: Thu, 10 Aug 2017 21:44:28 -0700 Subject: gpu: nvgpu: add NVGPU_SUBMIT_GPFIFO_FLAGS_RESCHEDULE_RUNLIST NVGPU_SUBMIT_GPFIFO_FLAGS_RESCHEDULE_RUNLIST causes host to expire current timeslice and reschedule from front of runlist. This can be used with NVGPU_RUNLIST_INTERLEAVE_LEVEL_HIGH to make a channel start sooner after submit rather than waiting for natural timeslice expiration or block/finish of currently running channel.
