From 394e9a14c63d58e0f45323629a3f9ce1e5bf0215 Mon Sep 17 00:00:00 2001 From: Emily Deng Date: Tue, 28 May 2019 10:17:04 +0800 Subject: [PATCH] drm/amdgpu: Need to set the baco cap before baco reset For passthrough, after rebooted the VM, driver will do a baco reset before doing other driver initialization during loading driver. For doing the baco reset, it will first check the baco reset capability. So first need to set the cap from the vbios information or baco reset won't be enabled.
