From 384872846f719760645dbe1b0c70edccb9cc941a Mon Sep 17 00:00:00 2001 From: Jack Xiao Date: Fri, 25 Jan 2019 14:11:35 +0800 Subject: drm/amdgpu/mes: add amdgpu_mes driver parameter amdgpu_mes, which is a driver scope parameter, is used to whether enable mes or not. MES (Micro Engine Scheduler) is the new on chip hw scheduling microcontroller. It can be used to handle queue scheduling and preemption and priorities.
