General CPU Discussion / Re: Power10 announcement from Raptor soon?

« on: October 03, 2023, 09:46:35 pm »

Didn't the Raptor Computing Twitter indicate that a Power10 was a huge CPU that would necessitate a single socket EATX motherboard? I want a Blackbird II: Free Software Boogaloo as much as anyone, but am tempted to think the person delivering the info has mixed something up... maybe a LibreSOC design at its heart, say?

Operating Systems and Porting / Re: [NEWS] Fedora 39 Beta

« on: September 22, 2023, 06:34:06 am »

Recent announcements that both GNOME and KDE Plasma may ship in Fedora 40 without an X11 session (so that way it doesn't need to be supported in the next RHEL).

It probably won't be a (big) problem for the Talos II, since I have a WX7100 GPU. It *may* be a problem for my Blackbird since I explicitly run that strictly on the BMC framebuffer as a low-end test.

Well, hopefully that won't break anything on my Blackbird running Xfce. I bop over to GNOME every couple of months to kick the tires, go "welp this still isn't for me," and hop back.

All the recent announcements about X11 make me more worried about Fedora 40.

What's up? You think they're going to shovel Wayland onto everyone prematurely with a "good luck suckers" to X users? I swear, it feels like people have lost their fool minds for anything outside a narrow band of mainstream use cases...

Applications and Porting / Re: [DEV] An attempt to package chromium for ppc64le in the official Fedora DNF repo

« on: September 10, 2023, 01:36:43 pm »

I just want to say how much I appreciate this. Though I love using Firefox as my daily driver and ClassicHasClass is making great progress toward fully porting its JIT for everyone, it would be nice to have Chromium to fall back on for the odd page that doesn't test on as many other browsers as it should.

Please note that Fedora 38 has defaulted to Wayland. HOWEVER due to unmet conditions in udev rules, it is actually reverted to x11

To fix this issue, please consult https://9to5linux.com/how-to-enable-wayland-for-hybrid-nvidia-graphics-on-fedora-linux-38-workstation

Can I assume I’m in the clear because I use Xfce and literally hop into GNOME about once a month just to make sure it still works?

What is `blink`?

The rendering backend for Chromium/Chrome, I'd guess.

Yeah, there needs to be another condition to account for that possibility - ppc970 and friends are POWER4 derivatives and have their own special mcpu entries.

Nice work. I have one question: for PPC64 BE, would Power Mac G5s running 64-bit Linux run afoul of the -mcpu=power7 flag?

I have a silly recurring bug that's been in place since my original install of Fedora 37: periodically xscreensaver clears its power management settings and I'll need to re-enable them. There hasn't been much rhyme or reason - every two weeks to a month, it happens out of the blue.

Which DE are you using?

Xfce, with the DE's native screensaver app removed.

I'm not sure about the hardware renderer, but the devs consider it indispensable for the true color software renderer. I'd expect gains north of 50% when intrinsics are enabled.

Applications and Porting / GZDoom

« on: July 30, 2023, 12:49:02 pm »

I talked about this a bit in the #talos-workstation channel over on Libera.Chat, but here goes: the short answer is that GZDoom works. All of the many libraries GZDoom takes advantage of run natively in Power, save for Asmjit, which is used to speed up execution of ZScript. I was wrong in the crispy-doom thread: enforcing -mcpu=power9 made a significant performance difference over the stock build options, but -DNO_WARN_X86_INTRINSICS makes no difference because of a prior commit that disables intrinsics outright for non-x86 architectures (apparently tied to disabling AsmJit for those platforms). With that limitation in mind, the biggest single issue for GZDoom speed comes down to a lack of SIMD optimization, which apparently makes a small difference in the hardware renderer and a very big difference in the true color software renderer. From what I've read the 8-bit software renderer doesn't leverage SSE2, and it flies at 1440p or higher on my eight core machine.

GZDoom currently detects Power9 as ppc64. Defining ppc64le as a platform and then forcing -DNO_WARN_X86_INTRINSICS specifically for it would probably be a lot less demanding than generating hand-tuned Power assembly, but I do not know whether that would break the current method of disabling AsmJit. Whether this would work on Power8 is up for debate - I don't know if its lack of VSX-3 would impact SSE translation. I need to allocate more time to scrutinize the source and figure out what needs patching, but if anybody wants to beat me to the punch, they are welcome to.

GPU Compute / Accelerators / Re: AMD Radeon RX 6800, 6800 XT and 6900 XT status?

« on: July 25, 2023, 08:23:44 am »

Reporting with an RX 6600 that’s been cheerfully hassle-free since kernel 6.1. So long as you hit that criterion, the 6700 should be a delight.

Edit: Never mind, yarn is in the Fedora repositories as yarnpkg. That'll teach me to run off to a conclusion... VS Codium compiled successfully with no errors, but no matter where I point Electron within the folder hierarchy, it doesn't seem to actually run. Suggestions are welcome.

if anyone here has a gpu better than vega 64 let me know what your FPS is

Has the patch been merged? I have an RX 6600 and can take a crack at it later in the week.
