GPU Compute / Accelerators / Re: Intel Arc A770 - failed experiment
« Last post by Hasturtium on February 12, 2026, 09:24:16 pm »
I am rolling my machine over to Fedora within the next couple of weeks. I’ll boot it with the Arc A380 I have kicking around and see if I can coax it into working.

I haven't had a chance to try it yet, but I don't see anything obviously wrong with your code.

https://github.com/ioquake/ioq3/pull/860 for supporting LE

@ClassicHasClass @power9mm could you please help review the PR for me? Many thanks

Yeah I saw the update, I currently don't own a power system at the moment to try it out. Waiting on the new systems to roll out for now. I would try the CPMA mod as that was having bad performance (and its one of the only active mods for quake 3)

edit: saw it was ioquake3... the main dev is.. eccentric to put it lightly. Eager to try the quake3e commit though. Thanks for that.

Thanks, that indeed fixes the build issue for me. But I'm still getting the same runtime issue as before - a segfault after loading the first level.

Please run the game with gdb and paste the stacktrace to gist.github.com or pastebin and share the link here

Okay I added a basic support PPC64LE

It's pretty much straight forward changes https://github.com/ispc/ispc/pull/3735

at this stage it has no PPC-specific ISPCTarget enum values, no ISA enum entry, no .ll builtin files. I hope this would create the foundation for developers to further extend it.

Operating Systems and Porting / Re: [NEWS] Linux 6.18

I just compiled version 6.18.2 for Ubuntu a few days ago, and it works fine on Power. On Debian, however, it still doesn't work. Ubuntu must have made some updates to fix the problem. I remember it didn't work on Ubuntu either until recently. I need to figure out if it's a firmware issue, a Mesa driver issue, or something else. I'm looking into it with Gemini.
