From 619f02aefc587e5e2821cd84b584eba199c97c9e Mon Sep 17 00:00:00 2001 From: Eduardo Habkost Date: Wed, 27 Sep 2017 16:56:31 -0300 Subject: [PATCH] pci: conventional-pci-device and pci-express-device interfaces Those two interfaces will be used to indicate which device types support Conventional PCI or PCI Express buses. Management software will be able to use the qom-list-types QMP command to query that information.
