fastppcx86 - an x86-64 userspace emulator for power8 and up.

I don't know how to program, I just understand the concepts of hardware emulation. I forked this from FEX-Emu a few months ago. Myself and another contributor used a mixture of local llms running on our power hardware and claude code. All work was done on Arch Power maintained by kth5. There is a lot of work to do as I only have a power8 machine, my co-contributor has a power9 workstation.

I don't know if this is the appropriate forum for this post.

Edit: This requires a 4k page size. I don't have 64k setup at the moment.

Sure seems appropriate to me. I'll have to try it out.

I linked the wrong repo originally, apologies.

Edit:

This video was tested with the currently available git repo:

Currently working on 64k page size support. It's in it's infancy and things may be broken. With native wine (pp64le wine) it works to launch Cyberpunk 2077, Witcher 3, rimworld.

edit: wine-ppc64le is on 11.16 and enables sparse topology support. https://github.com/jbettcher-wg/wine-ppc64le

Everything I've been doing has been using Arch POWER. https://archlinuxpower.org/

Excellent! I'm still having trouble with current kernels on my system and the particular cards I have, but once I get that figured out, I want to play with this more (it's Fedora, so it's 64K pages).
