From 5228644c5d40e413a13f3a471e4b5b1e3c382050 Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Fri, 8 Apr 2016 15:45:13 -0400 Subject: [PATCH 0495/1110] drm/amdgpu: add a new set of rlc function pointers Different asics tend to have different ways to interact with the RLC. This just covers enter/exit of safe mode for updating CG and PG state, but could be extended to cover other RLC operations in the future if necessary.
