I reverted this commit on top of the current amd-staging-drm-next (40cc64619a2580b26f924bcabdefd555e7831a14), my system is then booting ok. It seems to do some specific programming for vega10+ parts which is not correct for previous families/versions parts. commit 43ee614432d841184b158af27fda66a0929fe252 (refs/bisect/bad) Author: Emily Deng <<a href="mailto:Emily.Deng@amd.com">Emily.Deng@amd.com</a>> Date: Tue May 28 10:17:04 2019 +0800 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.
