From 232706619f7b9ff1532e95e0a2f38bc5b78d22d3 Mon Sep 17 00:00:00 2001 From: "Roger.He" Date: Tue, 14 Mar 2017 16:47:30 +0800 Subject: [PATCH] drm/amdgpu: increase IH ring buffer size to avoid overflow We originally limited the IH to 4k on tonga since it uses bus addresses directly rather than GPU MC addresses, so it needs contigous physical memory. This brings it inline with other asics.
