First, you will need a few things. (1) a small cache of binaries. You'll need to put these into ~/stand-test-root/cache. You can find the tarball at freefall.freebsd.org:~imp/cache.tar. You can just extract this in ~. These are the linux kernels I'm testing with. (2) The latest qemu-system-aarch64 (I think ports/pkg version of emulators/qemu is recent enough). If not, I know the latest master of qemu project works. (3) A recent enough universe that the building of stand will work for all the architectures that I build. You can hack the ARCHES line near the top of tools/boot/full-test.sh if need be, but you'll need at least amd64, arm64 and maybe riscv (I don't have a good way to filter arches in this script yet, since it's at an early state of development. (4) Build the kernel for at least arm64 and use it as an 'override'. I do this by sudo -E make installkernel DESTDIR=$HOME/stand-test-root/override/arm64-aarch64 TARGET=arm64 after building the kernel. The script is designed to use kernels and binaries from the latest CDs to do the testing, but has a way to override the kernel and since we need to fix arm64... (5) You'll need to build the images. If you've done 1-5 correctly (and I've not missed anything), then "cd /src; sh tools/boot/full-test.sh" will create all the images and scripts to run qemu. There should be no errors, though warnings about zfs.ko etc missing from powerpc is fine (and ignored by the script already). (6) There will be a script to recreate this created in $HOME/stand-test-root/scripts/arm64-aarch64/linuxboot-test.sh. Just run it with 'sh'. And extra args are passed to qemu, so '-s -S' for gdb and '-d trace:gicv3\* -D /tmp/gic.log' for verbose gic tracing (spaces are important). There's also a linuxboot-test-raw.sh which boots w/o EDK2+Linux.efi but loads the kernel directly. and freebsd-test.sh which uses EDK2+loader.efi to boot FreeBSD w/o kboot at all.
