Subject: [PATCH v2 0/3] dom0less pci passthrough support on Arm part 1
Date: Wed, 20 Aug 2025 12:28:13 +0000 [thread overview]
Message-ID: <cover.1755683961.git.mykyta_poturai@epam.com> (raw)
This series adds basic PCI device enumeration in Xen. This will allow us to not
rely on Dom0 enumeration for supported controllers, which will enable PCI
passthrough for dom0less setups.
Enumeration is disabled by default and can be enabled with "pci-scan" cmdline
option. Discovered devices are added to Xen and assigned to dom_io by default.
