From 61e113067b636fe73d5d0ac877bcfcebe7cfd034 Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Mon, 22 Aug 2016 13:50:22 -0400 Subject: [PATCH] drm/amdgpu: wire up a pci shutdown callback MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Normally on shutdown or reboot we don't care about necessarily making sure the hw is in a good state because the system is about to be powered down or reset. However, after a shutdown or reboot in a VM, it's best to tear down the hw properly otherwise there can be problems with the next VM use.
