Hello. We have never considered QEMU as an option so I can't tell whether it's working.
We are testing the Cygwin runtime and the GCC toolchain linked with it built with Linux->Windows cross-compiler on self-hosted GitHub Actions runner running on Windows Arm64 VM with WSL leveraging WSL interop for native code execution. This https://github.com/Windows-on-ARM-Experiments/newlib-cygwin/actions/runs/15698761968 is an example how we test whether the Cygwin can be build in a similar way as on the https://github.com/cygwin/cygwin and whether there are no regression to x64 builds. This https://github.com/Windows-on-ARM-Experiments/mingw-woarm64-build/actions/runs/15676501309 is an example how we test Cygwin as a part of the GNU toolchain and how we are running the Cygwin testsuite. Please, let me know if you have any questions about the project.

Check the cygwin-patches mailing list, and the cygwin git log. Lots of Aarch64 related patches. > On a Raspberry Pi 5 "botspot-VM" https://github.com/Botspot/bvm installed > a Win11 for me fairly happily and despite it not being the fastest machine > it is closer to viable than I might have expected. > And on an ARM Mac you have a choice between UTM and Vmwate Fusion (and > possibly now virtualbox).

Yeah, extra hardware might be hard to come by for "just try", and CI might also have the same problem. That is why I ask for qemu.
