From 43b9176faae1543d1a190db8eb098a8284d364f3 Mon Sep 17 00:00:00 2001 From: Shaoyun Liu Date: Fri, 28 Apr 2017 16:14:59 -0400 Subject: [PATCH] drm/amdgpu: Reserve 0-2 invalidation reg sets for none-amdgpu usages Firmware used reg set 2 for tlb invalidation. AMDGPU can start from reg set 3 to avoid the conflict. AMDKFD will use the reg set 0 or 1 when necesary.
