From 8fb6e528c399e54e5e2621d71a1037ab8ed89478 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.
