Operating Systems and Porting / Re: [NEWS] Fedora 41 is out!

Point the symlink /etc/systemd/system/default.target to /lib/systemd/system/multi-user.target and reboot, and it should come up with a text console login. Log in, do a startx (assuming your .xinitrc is configured) and away you go.

I realize this sounds like a non-solution, but the solution for me is to textboot and bring up X11 (or, if I'm feeling masochistic, Wayland) manually -- no display manager at all.

Is it still possible to fire up an X11 session? Are the packages gone and it can't be done anymore?

Well GDM has disabled X11 Session. Users are forced to go with Wayland moving forward. To me it makes no difference because X11 apps can function fine with XWayland

Yet another reason not to use gdm for session management ...

At least for 41, there was https://copr.fedorainfracloud.org/coprs/g/kdesig/plasma6-x11-unsupported/ . GNOME worked in X11 still, and I think that remains the case in 42.

I'll do my normal once over in a week or two when the packages have settled. Good you haven't had any major issues.

Wayland is fine if you have a GPU. If you don't, it runs everything through llvmpipe. On my 4-core Blackbird with AST graphics it worked fine but the fans never quit running (but when I switched to X11 they throttled back down again).

Ugh. That's not encouraging.

General Discussion / Re: POWER11, "Cirrus+" Can any of this be substantiated?

Haven't heard of this yet but maybe some stuff has leaked from the NDA partners.

This is going to sound like a flippant response and it really isn't, but pretty much any debugger would do (I use gdb but lldb should handle it also). You could throw an __asm__("trap\n") in your code and you'll drop into the debugger at that point, from which you can single step and look at the registers as you go along.

General OpenPOWER Discussion / Re: It looks like you have 1 guarded cores

Likely there was some glitch that caused one of your cores to get guarded out. You can clear this condition from the BMC: https://www.talospace.com/2020/05/the-case-of-disappearing-core.html

Applications and Porting / Re: [GAMES] Quake 3 source port with Vulkan renderer (vkQuake3)

« on: March 09, 2025, 09:58:13 pm »

I'm happy to advise, but I can't really do much coding for it. I'm still committed to maintaining the Firefox JIT (in at least the current state) and the DOSBox JIT and my actual coding time in front of the Talos II is increasingly limited.

That said, https://github.com/ioquake/ioq3/blob/main/code/qcommon/vm_powerpc.c looks like where you'd need to do most of the work to get ppc64le to work. ppc64 is a supported target, so you'd need to audit this for endianness and write ppc64le-specific code paths for those sections that assume big endian. That may be sufficient to get it off the ground.

It probably could be hacked to work on ppc64, though keep in mind that Microsoft VMX128 != AltiVec/VMX (and certainly not VSX) even though there is some overlap.

Probably, but it's always cleaner if you minimize the update delta. 41 has been working OK for me so far. That said, you could upgrade to 41 after 42 comes out, and then immediately upgrade to 42.
