Subject: [PATCH v7 6/7] docs/man: modify xl-pci-configuration(5) to add 'name' field to PCI_SPEC_STRING
Date: Tue,  5 Jan 2021 17:46:41 +0000	[thread overview]
Message-ID: <20210105174642.2754-7-paul@xen.org> (raw)
In-Reply-To: <20210105174642.2754-1-paul@xen.org>

From: Paul Durrant <pdurrant@amazon.com>

Since assignable devices can be named, a subsequent patch will support use
of a PCI_SPEC_STRING containing a 'name' parameter instead of a 'bdf'. In
this case the name will be used to look up the 'bdf' in the list of assignable
(or assigned) devices.
