Florian Fainelli 0cf7c54023 armvirt: Resync kernel configuration The 4.14 kernel configuration defaulted to a v4/v5 multiplatform while 4.9 was using a v6/v7 default configuration. Resync 4.14 against 4.9 so they are nearly identical. Signed-off-by: Florian Fainelli <f.fainelli@gmail.com>		2018-01-12 15:14:27 -08:00

This is intended to be used with LEDE project to provide image for use with
QEMU ARM virt machine.

Run with qemu-system-arm

	# boot with initramfs embedded in
	qemu-system-arm -nographic -M virt -m 64 -kernel openwrt-armvirt-32-zImage-initramfs

	# boot with accel=kvm
	qemu-system-arm -nographic -M virt,accel=kvm -cpu host -m 64 -kernel
	openwrt-armvirt-32-zImage-initramfs

	# boot with a separate rootfs
	qemu-system-arm -nographic -M virt -m 64 -kernel openwrt-armvirt-32-zImage \
	  -drive file=openwrt-armvirt-32-root.ext4,format=raw,if=virtio -append 'root=/dev/vda rootwait'

	# boot with local dir as rootfs
	qemu-system-arm -nographic -M virt -m 64 -kernel openwrt-armvirt-32-zImage \
	  -fsdev local,id=rootdev,path=root-armvirt/,security_model=none \
	  -device virtio-9p-pci,fsdev=rootdev,mount_tag=/dev/root \
	  -append 'rootflags=trans=virtio,version=9p2000.L,cache=loose rootfstype=9p'

Run with kvmtool

	# start a named machine
	lkvm run -k openwrt-armvirt-32-zImage -i openwrt-armvirt-32-rootfs.cpio --name armvirt0

	# start with virtio-9p rootfs
	lkvm run -k openwrt-armvirt-32-zImage -d root-armvirt/

	# stop "armvirt0"
	lkvm stop --name armvirt0

	# stop all
	lkvm stop --all

The multi-platform ARMv8 target can be used with QEMU:

	qemu-system-aarch64 -machine virt -cpu cortex-a57 -nographic \
		-kernel openwrt-armvirt-64-Image-initramfs \
