Subject: [PATCH v3 01/18] virtio: pci: Allow exclusion of legacy driver
Date: Thu, 21 Apr 2022 16:10:59 +0000 [thread overview]
Message-ID: <20220421161116.1202023-2-ascull@google.com> (raw)
In-Reply-To: <20220421161116.1202023-1-ascull@google.com>
Add a new config to control whether the driver for legacy virtio PCI
devices is included in the build. VIRTIO_PCI_LEGACY is included by
default when VIRTIO_PCI is selected, but it can also be independently
toggled.
