From db08244a3a7ec312dfed3fd9b88e114281215458 Mon Sep 17 00:00:00 2001 From: Matthew Rosato Date: Thu, 15 Oct 2020 09:16:07 -0400 Subject: s390x/s390-virtio-ccw: Reset PCI devices during subsystem reset 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 qdevs to be reset during subsystem reset.
