Subject: [PATCH 11/11] virtio: pci: Allow exclusion of legacy driver
Date: Sun, 20 Mar 2022 11:41:18 +0000	[thread overview]
Message-ID: <20220320114118.2237795-12-ascull@google.com> (raw)
In-Reply-To: <20220320114118.2237795-1-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 indepedently
toggled.
