Hello,

My branches are at https://github.com/mediouni-m/qemu

whpx-v1 corresponding to this RFC, but latest rev of the whpx branch has some 
fixes

Have some additional notes and binaries here too: 
https://github.com/mediouni-m/qemu/releases/tag/whpx-v1.1

Thank you,
-Mohamed

Syntax that I use is -M virt,accel=whpx,its=off -m 2048-cpu cortex-a72 -bios 
share/edk2-aarch64-code.fd.

And on some kernel versions, you’ll also need irqchip.gicv3_nolpi=1.

I don’t think I saw this particular one before… which Windows version and 
hardware are you testing this on?
