Hi Andrew, Very interesting, I was thinking about the same, for testing arm64 versions. I have some experience with qemu, although I mostly use VirtualBox. It is quite possible to use UEFI boot with qemu. I presume the emulated arm64 machine is good enough for compilations, for actually testing CinGG you probably need more??
as for runtime it works via vnc (!) on 4 (2ghz max) + 4(1.5 ghz max) arm core and 2 gb ram (+zswap around 1.4 gb shared with android 10) . sometimes it works fast enough (realtime) with even fullhd h264 video, sometimes not - probably due to cpu freqency/sheduling enforced by kernel)
more memory, (-m 2047) more -smp :)
there is link for opensuse install, you can use pre-installed os image
https://en.opensuse.org/openSUSE:AArch64#Using_an_emulator
or debian arm64 image (also pre-installed, so no need for multihour long install)
https://wiki.debian.org/Arm64Qemu https://cdimage.debian.org/cdimage/openstack/current-10/
you can prepare specific source image with pre-downloaded/unpacked/patched source and add this as second hdd...
A problem might be missing build utilities, I know a programmer who (for fun) wanted to build a CinGG for macOS had problems there.

because my patch series tend to fail on x86 while working on arm, I hope those links will help in creating virtual arm debian install for testing
official qemu wiki

link from this wiki to older (2017) guide, you probably want to change debian distro name in d/l links
