From 7eb48d9680b5451d2ce6ca6994cd290dbf599cb6 Mon Sep 17 00:00:00 2001 From: Scott Murray Date: Wed, 23 Nov 2022 14:24:45 -0500 Subject: linux-%: Tweak kernel configuration for KVM demo guests Rework the kernel configuration fragment application to prune out a bunch of the configuration for physical hardware for the virtio-aarch64 kernel. As well, add a virtio guest kernel specific fragment to enable a PCI CAN device driver that works with QEMU's emulation. That will provide a fallback until something can be worked out with respect to virtio-can.
