Talos II / Re: Ubuntu 20.04 5.4.0-167: kexec load failed
« Last post by Hasturtium on Today at 12:23:42 pm »
When I dallied with Ubuntu 24.04 earlier this year I seem to recall having issues with the stock 6.8 kernel that manifested in not being able to use my Radeon W6600. It would simply hang and not respond to the kernel's attempts to initialize it. That isn't the same as not being able to boot at all, but maybe you should consider trying a different version altogether?

I'm totally fine with the mods moving the thread if they feel there is a better location.  :)

Unfortunately though this problem has returned, and running
Code: [Select]
update-initramfs is not resolving the issue. Booting the old kernel works, but of course I can't stay on the old kernel forever.

The problematic kernel in this case is: 6.8.0-87-generic



Anyone have any suggestions for additional debugging I could do?

Applications and Porting / Re: [DEV] LuaJIT PPC64 support
« Last post by power9mm on November 07, 2025, 05:05:40 am »
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...

Hi,

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.

Applications and Porting / [DEV] Electron support for ppc64le
« Last post by tle on November 04, 2025, 05:47:04 pm »
Electron is a well known web-based stack for cross-platform application development. It is not my cup of tea but many popular apps such as VS Code, Atom, Slack, etc are built with it. So having it support ppc64le upstream is definitely a big win for us all.

There is a ticket https://github.com/electron/electron/issues/15691 to gather efforts from the community to get the support implemented. lex-ibm has been maintaining his own build script which is known to work well up to v37. Because he is occupied with other priorities, it would be great if any member could give him a hand to:

* Get his build script to support latest v39
* Extract all patches and submit PRs upstream

General CPU Discussion / Re: Has anyone done the Phoronix suite recently?
« Last post by mparnaudeau on November 04, 2025, 08:26:24 am »
I see this old message only right now ...

In fact, one year ago, I wrote this article to state on the different Phoronix articles, aggregating information, that concerned performance of Talos 2 / POWER9:
http://www.powerpc-lab.org/linux/2024/09/28/talos2-performance-evaluated-in-2018-2019.html

Based on that, I also wanted to know what has changed since, if some benchmarks and projects got benefit of the feedback provided initially.

This is why I am preparing another article, but this time more oriented toward my configuration (2x 4-Core). I found a reduced set of x86 machines in the same theoretical range of performance. But they mainly have run old versions of benchmarks. So, I also tried to find the most recent versions that have results for the processors I identified.

At the end, I would like to address some issues, contribute to some projects ... and to various phoronix-test-suite repositories (not sure they receive many changes though).

@migsutu would you be able to send me the full `dmesg` logs?

Swapping back to the Radeon after installing with the Geforce has successfully booted and works as expected. All apps working(including Kmail which was broken in the FC42 PPC64LE). System feels snappy with proper graphics drivers running. Very nice release now.

tle, I tried the GNOME version which I assume is the main workstation version. Same error on installation with the Radeon error mentioned above.

If I can help troubleshoot something, let me know and I will see what I can do on this end.

Fedora has just bumped GNOME to 49.1

Everything still works nicely. I am working with upstream packagers to re-introduce ppc64le packages for 0ad game and let's hope I could get ziglang ppc64le rpm package in Fedora 44.

I attempted installation of Workstation and KDE Plasma Edition with the release version. I am getting error "drm:radeon device init [radeon]*ERROR* Unable to find PCI I/O Bar"

No GUI ever comes up on the main graphics at this point. I went back to my old Fedora 42 Live thumbdrive and it correctly boots and loads up. The Beta of 43 seemed to work fine, but something appears wrong with Radeon drivers on the PPC64LE release with the release version. Unfortunately I don't have an Nvidia card to try.

Could you please confirm if you could re-produce the same issue with GNOME version?

That could be related to the kernel and amdgpu version of that installer image.
