From fc28f89157254ddf638e52ea20cdfe675ab4c382 Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Tue, 11 Oct 2016 15:21:25 +1000 Subject: radv: check driver name before calling amdgpu. This checks the kernel driver name is amdgpu before calling libdrm_amdgpu. This avoids the following error: amdgpu_device_initialize: DRM version is 1.6.0 but this driver is only compatible with 3.x.x when run on a machine with i915 graphics as well as amdgpu.
