Tiwei Bie	8129b9e8e3	um: vfio: Support adding devices via mconsole ... It can be used when we want to pass through PCI devices to UML while it's up and running. PCI devices can be passed through to UML using the same syntax as the command line option: (mconsole) config vfio_uml.device=<domain🚌slot.function> Signed-off-by: Tiwei Bie <tiwei.btw@antgroup.com> Link: https://patch.msgid.link/20250709010021.1076902-1-tiwei.bie@linux.dev Signed-off-by: Johannes Berg <johannes.berg@intel.com>	2025-07-11 08:49:44 +02:00

Tiwei Bie	a0e2cb6a90	um: Add VFIO-based virtual PCI driver ... Implement a new virtual PCI driver based on the VFIO framework. This driver allows users to pass through PCI devices to UML via VFIO. Currently, only MSI-X capable devices are supported, and it is assumed that drivers will use MSI-X.
