Applications and Porting / Re: [DEV] Is there any tool to detect the logic that might be impacted by endianess?

« Last post by tle on September 19, 2025, 04:32:39 am »

Most of the time I would not get any error but likely run into unexpected behaviour when running the game or apps.

Your verbs are unclear - "would not" and "likely run into" are future tense, as in, you are projecting what might occur.  Are you saying the entire code base compiled but has odd behavior when running in Big-endian mode?

If you can compile the source code, run it in Little-endian mode and see if the same unexpected behaviors are present.

Yes, I do project there are potential issue if the app is complex. Sometimes the app just crash early on, but sometimes it does not. The latter scenario can be real pain if applications are lacking of tests. I agree with you that one could always do comparison with ppc64le version. My question is simply curiosity if there is any tool that could analyze the codes / assembly / bytecodes to pick up places that might susceptible to endianness issue

Operating Systems and Porting / Re: [NEWS] Fedora 43 Beta - please help the community test this release

XFCE runs flawlessly as expected.

It's unfortunate that many X11-based WM are not picked up by GDM (Wayland only now) so I have to use SDDM instead.

Firmware / Re: Cross-build compiler environment for SBE

« Last post by TimKelly on September 19, 2025, 03:42:07 am »

I have not.  Certainly it looks like there are more instructions, but I gave up after getting internal compiler errors when ppe42-gcc tried to build ppe-binutils.  It was in the internal register allocator (ira) and both the subdirectory configure and Makefiles would not respect flags passed to them, as I documented at

https://forums.raptorcs.com/index.php/topic,617.0.html

However, I did not apply patches to what was in Raptor's source code tree.  Thank you for pointing out the different repository.

GPU Compute / Accelerators / Intel Discrete GPU demise is inevitable

« Last post by tle on September 19, 2025, 02:11:15 am »

Intel announces the partnership with NVIDIA. The $5b 'bailout' deal seals the fate of Arc Discrete GPU ambition and Intel will ship CPU with NVIDIA GPU tech.

I was hoping that one day we might see 1st class driver for non-x86 Linux architecture... wishful thinking I know

I have not tried to but wondering have you checked https://github.com/open-power/ppe42-gcc ?

Looking good so far.

Xonotic no longer crash, in fact I think the crash was related to Fade Coronas GPU option

0ad was unfortunately disabled for ppc64le, I am trying to get the maintainer to backport some patches to get it build again https://bugzilla.redhat.com/show_bug.cgi?id=2396311

User Zone / Re: Unable to boot with NVIDIA GT710 installed

« Last post by bernie on September 17, 2025, 06:49:15 pm »

Interesting, I will have a look out for a 750 Ti to compare... On raw processing power, the 780 Ti seems like it should be better, I did not realise that the NVK version would make such a difference.

Nice that you got reclocked.

Bernie  i testing some GPUs and Drivers to get better perfomance on Raptor Backbird and Gnu Systems, so  my raptor-blackbird it is original raptor SFF-mTX so i like this factor,however i not have much space for big GPUs, so it only fits gpu low profil, single slot, so i have gpus to testing compat to Gnu OS like intel arc pro a40, which at the moment it is not working  as it need some patches on libdrm, but this arc gpu may work OK without firmware but i untested yet. So what i using now is Quadro k1200 which it is Maxwell, maxwell it is newer than Kepler and still do not using signed firmware on host. k1200 it working nice and it compat to NVK 1.4, however Kepler  is only compat to NVK 1.2. Why so import NVK? On Gnu system we do not have a Libre driver for video hardware decoder on Nvidia GPUs, howerver we can use the Libre NVK not just for gaming but for video decoder and encoder for smooth and hight  performance for video play and any vk-software acceleration ready, so this why Maxwell 1.0 shine.

So Bernie GPUs like  780 Ti and 710 is still Kepler, however there are  i high performance Maxwell gpu that do not need firmware y compat to nvk 1.4 as mine it is: Nvidia GTX 750 Ti or Nvidia GTX 750, this GPUs it is the best of the best for newer features and performances for Gnu OS.
