commit 163db6a72b660f0f3c9fe1d34e8f6b07ae6bd77d Author: Jan Beulich <jbeulich@xxxxxxxx> AuthorDate: Wed Dec 15 10:20:35 2021 +0100 Commit: Jan Beulich <jbeulich@xxxxxxxx> CommitDate: Wed Dec 15 10:20:35 2021 +0100 x86/PVH: permit more physdevop-s to be used by Dom0 Certain notifications of Dom0 to Xen are independent of the mode Dom0 is running in. Permit further PCI related ones (only their modern forms). Also include the USB2 debug port operation at this occasion. While largely relevant for the latter, drop the has_vpci() part of the conditional as redundant with is_hardware_domain(): There's no PVH Dom0 without vPCI.
