Operating Systems and Porting / Re: New Kernel 5.16 and new problem

« on: January 16, 2022, 07:28:47 pm »

I have not tried it yet, still waiting for official build from Fedora team.

However I do not think 5.16 is that much different to 5.14 because there aren't major change that benefits PPC.

The AMDGPU is still very unreliable so system freeze is expected. What pagesize do you compile the kernel with?

Operating Systems and Porting / Re: Fedora 35 (was F-34): going to 4k page size? Help needed

« on: December 08, 2021, 08:07:24 pm »

Any work on this topic in Fedora has now been undermined by the politics that is gripping large free software organizations.  This initiative is completely frozen and I can't say when it would resume.

During the Fedora 35 release cycle, many Red Hat employees joined the attacks on Dr Richard Stallman.  I wrote a blog about the human rights issues involved in these online mobs and subsequently received a number of malicious communications that undermine my voluntary work as a Fedora developer.

I would not expect Raptor to be keen on taking sides in these issues, after all, they made a big effort to attain the FSF RYF certification but the OpenPOWER hardware is coming from Red Hat's parent, IBM.  On that basis, I won't say a lot more about this but I feel that people who invested in this platform have a right to know that politics is getting ahead of important development issues.

Wondering if there is any similar initiatives for clang?

The performance problem is indeed libgraphene again: the fix seems present in Fedora's sources but it doesn't stick. I rebuilt it and the performance regression is largely gone. Here's a binary for those who want it: https://github.com/ebassi/graphene/pull/233#issuecomment-979687134

Still other F34 regressions are still present. It basically works, though. https://www.talospace.com/2021/11/fedora-35-mini-review-on-blackbird-and.html

Great thanks. Your patched libgraphene really boost the performance many folds. It is still not snappy like GNOME 3.36 but now much more usable.

It's OSS so let's contribute patches to improve the perf

Regarding the Chromium, I am flat out with work atm, I hardly have time for OSS atm. I will spend some time this XMAS break to bring the version up to date

It turns out the version of graphene that Fedora 35 ships has the perf patch (ref: https://src.fedoraproject.org/rpms/graphene/c/501dd9f22698c5ff64aaf34c0f5922ce5d694010?branch=rawhide)

However the performance is still sluggish compared to GNOME Shell 3.38

That's it:
https://github.com/ebassi/graphene/pull/233

I can see the PR was created in July yet there is no release since April so it is very unlikely that Fedora 35 or any other distro would have picked up this change.

Well I don't believe GNOME Shell / Mutter devs own PPC64LE/BE computers so it is very unlikely they would be able to pick up issues that are specific to PowerPC.

Announcement: https://www.redhat.com/en/about/press-releases/fedora-linux-35-now-generally-available

I don’t expect the GNOME Shell would be smooth. It’s been sluggish since GNOME 40.

Applications and Porting / [APP] The buildkite monorepo plugin now supports ppc64le agent

« on: October 25, 2021, 03:21:05 am »

So if you are using Buildkite CI/CD now, chances are you might have heard of the awesome monorepo-diff-buildkite-plugin.

This plugin helps detect changes to filesystems then trigger specified pipelines. I have been using this plugin at work for months and realise it does not support linux-ppc64le agent. So here we go after a Pull Request, the support is in

Yes because I and other contributors to the project have not time to port all patches to 87 or newer yet

I keep finding only up to version 87 and with last work done 4 months ago ... I can't find anything else unfortunately ... Or I don't know how to do the right procedure to find it ...

If the author does not support ppc64le or ppc64be, I think the users (that is us) should delve into the code to see if it could be ported over.

Perhaps you should google around to see if anyone has attempted to port this software to ppc64le yet

Operating Systems and Porting / Re: [NEWS] Debian 11 is out

« on: September 16, 2021, 11:58:11 pm »

When I bought my Talos II, I did a fresh install of buster

As mentioned elsewhere, I rebuilt my kernel for a 4k page size and created Btrfs filesystems with 4k

I recently made a dist-upgrade to bullseye, Debian 11.  As part of the upgrade, I rebooted into the 4k kernel from buster so I could continue accessing my Btrfs filesystem

Then I built a 4k version of the 5.10 kernel package from bullseye.  Rebooting into that and the system runs fine.  I pushed my kernel here:

https://gitlab.com/dpocock/linux-kernel-debian/-/tree/pocock/bullseye-ppc64el-4k

After a week or so I had a crash, I'm not sure if that is the bullseye kernel or if it is just what I was doing at that moment in time.  I've been doing some development with GStreamer and VAAPI for the AMD Radeon cards and that has also produced some crashes so I'm not sure if this is because of bullseye or the testing that I'm doing with the GPU.

GNOME appears to be slightly faster when switching workspaces compared to buster.

Any kernel log when it crashes?

Guys I inform you that with the help of Dan from the Fedora Project, whom I thank again, I was able to solve the problem of the audio bug on Fedora 34 that prevented me from turning up the volume.  The problem is what I had suspected for some time, the new Pipewire audio management software, which causes this nasty bug for those who use a dedicated internal sound card.  I performed the little procedure on the Fedora Wiki which makes me reinstall Pulse audio and delete Pipewire and the system is back to working normally.  I already told Dan that he said that as soon as he got my feedback he would inform the Pipewire team.

Could you please let me know the URL of the wiki?
