From 30471d5351cf397d2a080fdcb747c7eb354bfab8 Mon Sep 17 00:00:00 2001 From: Andrew Scull Date: Thu, 21 Apr 2022 16:10:59 +0000 Subject: [PATCH] virtio: pci: Allow exclusion of legacy driver 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.
