A Fedora 28 Remix for Tegra using i3

This is dedicated to older Tegra such as Tegra20, Tegra30 and Tegra114. It can work on Tegra K1, but at this time, using Fedora 29 is a better choice. Specially as Fedora 29 on Tegra K1 and later have support for GPU acceleration with nouveau.

The image integrates the grate-driver that provides a reverse-engineer mesa driver (FLOSS, but not yet upstream). This only advertises OpenGL 1.4 yet, but it can at least run glxgears fine. This is not the case with the softpipe driver on Tegra20.

There is also a HW video decode driver using [libvdpau_tegra||en].

Please use mpv or vlc from [RPM Fusion||en|RPM Fusion] for video acceleration.

This spin was only tested on Toshiba AC100 and Trimslice.

* Download [Tegra Fedora 28 Respin via torrent||en]

* Install the disk image on a sdcard

> SDCARD=/dev/sdc (to be adapted)

> xzcat Fedora-remix-tegra-i3-28-20180918.n.0-sda.raw.xz | sudo dd of=${SDCARD} bs=4M

You need a recent u-boot version with Extlinux support. I recommends 2018.09 release or later

To update the bootloader on tegra20 devices please see

Remind that paz00 still lacks keyboard support for the bootloader upstream. To have keyboard support you can to get:
There is a pre-built u-boot binary based on this tree in the same directory.

If you want to install the packaged grate-driver from an official Fedora 28 image:
> curl -o /etc/yum.repos.d/fedora-ac100.repo
This will replace mesa libdrm, but you can keep the fedora kernel

Interested in having an official i3 spin in Fedora?
For Tegra, it will depends on the upstreaming of the grate-driver, but I've submitted a PR to have a generic i3 spin. As some arm or aarch64 based devices that can output display, but may not be able to have enough accelerated desktop capabilities (Unless using a proprietary or downstream driver that won't be in Fedora). See if you want to help:

RPM Fusion is near 10 years old

10 years ago, one of the internal root Certificate Authority was generated for the project. The infra wasn't production ready yet, but few months later there was support for Fedora 8. One of the earlier message from the developers mailing list.

At that time, the idea to form a community shaped against Fedora was to bring people to work together on the same complementary repository for the distribution. Remember how Fedora started ? So this is still one root of the project.

RPM Fusion free available for fedora 22

As this concern was raised in several places already, I would like to announce that the RPM Fusion free repository is published since few days for Fedora 22.

At this time, only the free section is available, but it's also there for armhfp at the same time as i686 and x86_64. (no aarch64 but that's can be a secondary step if I manage to have a builder).

It's only a rebuilt for f21 packages made for f22. Several f22 specific updates will be pushed progressively.

If you previously had installed the rpmfusion-free-release for f22, but miss the updates for any reason, maybe you will need to re-install the release package or verify previously modified configuration files.

I'm still working hard to get the infrastructure migrated to Koji/distgit and it's unlikely that the migration process will be finished in time for f22 GA, but at least it will be possible for users to install working packages and for package maintainers to provide the needed bugfix updates for f22.

If you can help fixing FTBFS package for f22, please see the bug tracker for f22.

mesa 10.2 from git for Fedora 20

This has started as a attempt to test the improvements of the freedreno ARM driver, so I've made an updated mesa package (and newer libdrm) specially for testing.

You can grab it installing the kwizart-release repository and

yum update --enablerepo=kwizart-testing libdrm\* mesa\*

The updated mesa 10.2 package from git20140209 is available for i686 x86_64 and armv7hl. The final version is scheduled in 3 months from now (so it could be in Fedora 21 by default). This is a different branch from the 10.1 branch to be released soon.

I'm not interested in xorg-x11-drv-vmware in this case, and there is an ABI break behind, so you need to:

yum remove xorg-x11-drv-vmware

Also an interesting feature of the mesa 10.2 branch is the OpenMAX IL feature on AMD devices. I try to maintain libomxil-bellagio within fedora, so I'm interested in feedbacks on this topic. The AMD GPU I can test on doesn't seem to be compatible with the feature. But there are also probably few issues with libomxil-bellagio given the lack of upstream activity. Still you can test using:

yum install --enablerepo=kwizart-testing mesa-omx-drivers

VLC from RPM Fusion should be compatible with OpenMAX IL, and gstreamer has a plugin that should enter into Fedora at some point (currently in review).

Also the packaging git work is currently ahead of the fedora rawhide spec, so there are probably few patches that can be used in the next fedora package.

The first RPM Fusion push using Koji...

... was made on ARM secondary architecture, today!

RPM Fusion is available on ARM for both softfp/hardf. But until then, the published packages was built using mock from the Everything source repositories for each Fedora releases. Right now the process is in place to track packages as soon as they hit stable updates, so they will be automatically rebuilt on ARM.

The packages was published to free and nonfree updates repositories from f17 (even if it was EOL) to f19. But some packages still FTBFS on ARM. Nothing is started with fedora 20 on ARM yet.

This is a good step to have RPM Fusion to switch to Koji on x86 (primary) arches, but there is still lot of area to improve.

nvidia instancied kernel modules with the RPM Fusion package

With the new akmod-nvidia-331.20-3.fc19 released today comes an option to build the nvidia kernel modules several times. This is useful as advertised in the nvidia FAQ to "Minimize the software overhead when driving many GPUs in a single system" . That, specially when each GPU is processing different workload such as with CUDA applications.

You can use it by setting the following RPM macro, with up to 8 different kernel modules:
#File /etc/rpm/macros.nvidia - Set the number of nvidia kernel modules to build (up to 8)
%_nv_build_module_instances 2

Then you can use akmod-nvidia to automatically rebuild the kernel modules with the above option:
$ sudo yum install akmod-nvidia kernel-devel (or kernel-PAE-devel when using kernel-PAE)

If you previously had the package installed, and want to rebuild with the new option, you can use:
$ sudo akmods --force akmod nvidia

This will build the specified number of kernel modules along with the nvidia-frontend.ko
$ rpm -qpl ~builder/rpmbuild/RPMS/x86_64/kmod-nvidia-3.11.8-200.fc19.x86_64-331.20-3.fc19.x86_64.rpm

Then, you can modprobe the appropriate kernel modules, as mentioned in the FAQ, this command will assign two cards to the nvidia0 kernel module instance:
$ sudo modprobe nvidia0 NVreg_AssignGpus="0:01:00.0,0:02:00.0"

The Official documentation for the RPM Fusion packaged nvidia driver is still at nVidia How on the RPM Fusion Wiki.

vlc-2.1.0-pre1 available for fedora on x86 and ARM

The first pre-release version of the new vlc 2.1.x branch is available for fedora 18 users.

This realease has seen a lot of license changes for certains modules from GPLv2+ to LGPLv2+.

Others main changes for Linux are: Core:

- Audio core rewrite
- Add an audio fingerprinter


- Support for libopus
- Hardware acceleration improvements


-high10, high422 and high444 encoding support in h264


- Various improvements in DASH support
- HTTP support for Internationalized Domain Names
- Add support for VNC/rfb in view only mode
- Add support for Remote Desktop/RDP in view only mode

Specifically for the ARM build:

- Various NEON optmizations
- OpenMAX IL Videout output

This package is a rebuilt form the version already available in RPM Fusin for Rawhide/Fedora 20. I will made vlc 2.1 available for Fedora 19 as a regular RPM Fusion update once stable.

The build are available in my kwizart-testing repository for i686, x86_64, arm and armhfp for Fedora 18 only for now.

$ sudo yum install vlc --enablerepo=kwizart-testing

You can eventually report a bug on the RPM Fusion bugzilla tracking Rawhide if needed.

RPM Fusion now available on ARM

A quick note to say that I've released RPM Fusion free for Fedora 17 on ARM (for both softfp/hardfp).

Please follow this page for ARM users:

The install procedure should be exactly the same as for primary arches, but since a little fix is needed, I've made a dedicated link to the latest release RPM for f17:

$ sudo yum localinstall --nogpgcheck

There is no public infrastructure yet, but you can see the build logs here: softfp and hardfp.

If you want to build a package using any RPM Fusion dependency, you can install mock-rpmfusion-free.

The next step is to do the same for nonfree, then to build the updates repo.

Please enjoy and report feedbacks on the RPM Fusion mailing list and issue on (using "arm" architecture component if ever relevant).
