[DEV] LuaJIT PPC64 support

<< < (2/3) > >>

power9mm:
I remember this being the major hang up with the STALKER engine when getting it to compile for ppc64le (x-ray engine) i forgot what we did to get it to work and unfortunately i've lost all the code and work that was done due to theft of the hard drives i had been using in my system from a storage unit break in. There was some kind of working version of it though for ppc64... Also the guy who helped made it possible has vanished and most likely for the worst sad to say...

the latest available upstream version v2.1-20250826 has support for both ppc64
and ppc64el allowing luajit to be built successfully on both of these architectures.

That quote is really misleading, I thought for a moment that Mike Pall finally merged PPC64 support after like 10 years. But it's just openresty fork, it's had ppc64 and ppc64le support for quite some time already.

tle:
It's painful to convince Mike to review and merge such huge delta of changes to support PPC64 JIT. It's understandable taking into consideration and assumption that Mike does not own a POWER8/9 hardware.

I think I could try to review one of those stale JIT work and get it patched downstream in Fedora. If that approach proves successful, I strongly believe Mike would likely give his blessing to the JIT port after few years of real world usage downstream.

MPC7500:
Why not ping Pearson?
Maybe he is willing to donate hardware to him.

Kortaffel:
slightly offtopic, but SolidSilicon website went offline since april 1st, (or earlier). That power 11 announcement for somewhere Q12026 isnt coming.
Pearson is probably busy af, holding what little is left of OpenPower together
There's probably nothing to donate, or even new users, for an almost 10 year old power9 plattform at 5 grand
I saw on youtube in one of those webinars that IBM has transfered Power ISA developement to Bangalore, India. If IBM Usa doesn't care about the OpenPower side of things, then I'm certain that no one in India gives a damn.
