This series resolves a long term issue with Phylink and SFPs on DPAA2 hardware (LS1088,LS2088,LX2160) where a locking problem prevented the system from rebooting. Patches solving this issue existed prior to 6.2 but were not accepted upstream. See the original series on patchwork: https://patchwork.kernel.org/project/netdevbpf/cover/20221129141221.872653-1-vladimir.oltean@nxp.com/ And this thread on the Traverse forum: https://forum.traverse.com.au/t/reboot-command-regression-from-5-10-to-5-15-kernel/133/12 Signed-off-by: Mathew McBride <matt@traverse.com.au> |

This target generates images that can be used on ARM machines with EFI
support (e.g EDKII/TianoCore or U-Boot with bootefi).
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-armvirt-32-generic-initramfs-kernel.bin
# boot with accel=kvm
qemu-system-arm -nographic -M virt,accel=kvm -cpu host -m 64 -kernel
openwrt-armvirt-32-generic-initramfs-kernel.bin
# boot with a separate rootfs
qemu-system-arm -nographic -M virt -m 64 -kernel openwrt-armvirt-32-generic-kernel.bin \
-drive file=openwrt-armvirt-32-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-armvirt-32-generic-kernel.bin \
-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-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/armvirt/32/openwrt-armvirt-32-generic-ext4-combined.img.gz > openwrt-arm-32.img
qemu-system-arm -nographic \
-cpu cortex-a15 -machine virt \
-bios QEMU_EFI_32.fd \
-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/armvirt/64/openwrt-armvirt-64-generic-ext4-combined.img.gz > openwrt-arm-64.img
qemu-system-aarch64 -nographic \
-cpu cortex-a53 -machine virt \
-bios QEMU_EFI_64.fd \
-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 find EFI/BIOS binaries from:
- Compile mainline U-Boot for the QEMU ARM virtual machine (qemu_arm_defconfig/qemu_arm64_defconfig)
- 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/
