Add new package so we can use self-compiled bootloader during QEMU based testing and development. Backported fix[1] is needed for EFI boot from virtio devices. 1. https://patchwork.ozlabs.org/project/uboot/patch/20230424134946.v10.7.Ia5f5e39c882ac22b5f71c4d576941b34e868eeba@changeid/ Signed-off-by: Petr Štetiar <ynezz@true.cz>

This target generates images that can be used on ARM machines with EFI
|
|
support (e.g EDKII/TianoCore or U-Boot with bootefi).
|
|
|
|
There are two subtargets:
|
|
- armv7 for 32-bit machines
|
|
- armv8 for 64-bit machines
|
|
|
|
The kernel and filesystem images can also be used directly by QEMU:
|
|
|
|
Run with qemu-system-arm
|
|
|
|
# boot with initramfs embedded in
|
|
qemu-system-arm -nographic -M virt -m 64 -kernel openwrt-armsr-armv7-generic-initramfs-kernel.bin
|
|
|
|
# boot with accel=kvm
|
|
qemu-system-arm -nographic -M virt,accel=kvm -cpu host -m 64 -kernel
|
|
openwrt-armsr-armv7-generic-initramfs-kernel.bin
|
|
|
|
# boot with a separate rootfs
|
|
qemu-system-arm -nographic -M virt -m 64 -kernel openwrt-armsr-armv7-generic-kernel.bin \
|
|
-drive file=openwrt-armsr-armv7-generic-ext4-rootfs.img,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-armsr-armv7-generic-kernel.bin \
|
|
-fsdev local,id=rootdev,path=root-armsr/,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-armsr-armv7-zImage -i openwrt-armsr-armv7-rootfs.cpio --name armsr0
|
|
|
|
# start with virtio-9p rootfs
|
|
lkvm run -k openwrt-armsr-armv7-zImage -d root-armsr/
|
|
|
|
# stop "armsr0"
|
|
lkvm stop --name armsr0
|
|
|
|
# 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-armsr-armv8-generic-initramfs-kernel.bin \
|
|
|
|
With a EDKII or U-Boot binary for the QEMU ARM virtual machines, you can use these
|
|
images in EFI mode:
|
|
|
|
32-bit:
|
|
gunzip -c bin/targets/armsr/armv7/openwrt-armsr-armv7-generic-ext4-combined.img.gz > openwrt-arm-32.img
|
|
qemu-system-arm -nographic \
|
|
-cpu cortex-a15 -machine virt \
|
|
-bios bin/targets/armsr/armv7/u-boot-qemu_armv7/u-boot.bin \
|
|
-smp 1 -m 1024 \
|
|
-device virtio-rng-pci \
|
|
-drive file=openwrt-arm-32.img,format=raw,index=0,media=disk \
|
|
-netdev user,id=testlan -net nic,netdev=testlan \
|
|
-netdev user,id=testwan -net nic,netdev=testwan
|
|
|
|
64-bit:
|
|
gunzip -c bin/targets/armsr/armv8/openwrt-armsr-armv8-generic-ext4-combined.img.gz > openwrt-arm-64.img
|
|
qemu-system-aarch64 -nographic \
|
|
-cpu cortex-a53 -machine virt \
|
|
-bios bin/targets/armsr/armv8/u-boot-qemu_armv8/u-boot.bin \
|
|
-smp 1 -m 1024 \
|
|
-device virtio-rng-pci \
|
|
-drive file=openwrt-arm-64.img,format=raw,index=0,media=disk \
|
|
-netdev user,id=testlan -net nic,netdev=testlan \
|
|
-netdev user,id=testwan -net nic,netdev=testwan
|
|
|
|
One can obtain other EFI/BIOS binaries from:
|
|
- Distribution packages (such as qemu-efi-arm and qemu-efi-aarch64 in Debian)
|
|
- Community builds, like retrage/edk2-nightly: https://retrage.github.io/edk2-nightly/
