From e07cc4699127d882f619c978c215bf2a762b61fa Mon Sep 17 00:00:00 2001 From: Paul Spooren Date: Mon, 11 Oct 2021 10:33:26 -1000 Subject: [PATCH] x86/64: enable MMIO_CMDLINE_DEVICES for firecracker support This Kernel option allows to run OpenWrt witin a `firecracker` micro VM. Firecracker is a KVM-based tool for superfast booting VMs on x86_64 and aarch64. It makes rootfs available to the guest as a virtio-mmio device and passes its address via the kernel cmdline. A kernel without CONFIG_VIRTIO_MMIO_CMDLINE_DEVICES will not recognize the rootfs virtio-mmio device.
