From: Evan Quan Date: Thu, 5 Jul 2018 02:30:36 +0000 (+0800) Subject: drm/amdgpu: reduce the idle period that RLC has to wait before request CGCG X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=a5aedc2d18bcb33816545f39f13a37a0c86b3b3d;p=openwrt%2Fstaging%2Fblogic.git drm/amdgpu: reduce the idle period that RLC has to wait before request CGCG Gfxoff feature may depends on the CGCG(on vega12, that's the case). This change will help to enable gfxoff feature more frequently.
