Operating Systems and Porting / [NEWS] Fedora 35 is out folks
« on: November 03, 2021, 04:57:33 am »
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.

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

Been following up with upstream progress on supporting ppc64le https://gitlab.com/gitlab-org/gitlab-runner/-/merge_requests/2868

Once the MR is completed, this would no doubt make life easier for devs to host gitlab pipeline on linux/ppc64le

It is more convenient for ppc64le linux users who want to use this CLI to publish release

This proposal https://fedoraproject.org/wiki/Changes/PPC64LE_Float128_Transition is getting very old and no action has been done to roll this work forward. Wondering if anyone have more context on the delay?

Applications and Porting / [APP] CPUFetch now support POWER-based CPUs

Great thanks to the author for adding support for POWER-based CPUs. You could download and compile the program from GitHub https://github.com/Dr-Noob/cpufetch

Fedora COPR was doing migration to new datacenter last year. The move's seems to be progressing well.

From what I know, some POWER8 machines are now back online

Ref: https://pagure.io/fedora-infrastructure/issue/9059

That means we could now build custom RPMs for Fedora with COPR again

User Zone / How to get toolbox CLI running on Fedora
« on: April 29, 2021, 06:06:26 am »
Toolbox is a great tooling to create development containerised dev environment. I have been using this tool on x86_64 for 2 years at work.

With ppc64le, Fedora Infrastructure team does not support PPC64LE so users
have to build the base image manually:

Code: [Select]
git clone https://github.com/containers/toolbox.git
cd toolbox/images/fedora/f34
podman build . -t fedora-toolbox:34

Once done you could specify the image in toolbox command:

Code: [Select]
toolbox create --image fedora-toolbox:34
toolbox enter

Operating Systems and Porting / [NEWS] Fedora 34 is out!
« on: April 27, 2021, 09:55:32 am »
More info at https://fedoramagazine.org/announcing-fedora-34/

I have upgrade my Blackbird (with AMD R9 Nano GPU) from F33 to F34 successfully.

Everything works as expected though the animation of gnome-shell is sluggish.
