2020-10-15 Thread Matthew Rosato
Currently, a subsystem reset event leaves PCI devices enabled, causing issues post-reset in the guest (an example would be after a kexec). These devices need to be reset during a subsystem reset, allowing them to be properly re-enabled afterwards. Add the S390 PCI host bridge to the list of
