Fedora Remix for Tegra using i3 desktop environment

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.

The image integrates the grate-driver that provides a reverse-engineer
mesa driver (FLOSS, but not yet upstream). This only advertise 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 vdpau.

Please use mpv or vlc from RPM Fusion for video acceleration

This spin was only tested on Toshiba AC100 and Trimslice.

You need a recent u-boot version with extlinux support
I recommands 2018.09 release or later

To update the bootloader on tegra20 devices please see
https://github.com/NVIDIA/tegra-uboot-flasher-scripts

Remind that paz00 still lacks keyboard support for the bootloader upstream. To have keyboard support you can to get:
https://github.com/ac100-ru/u-boot-ac100-exp/tree/nvec-dev-mainline-master-2017-07-15
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 image:
curl https://repos.fedorapeople.org/repos/kwizart/ac100/fedora-ac100.repo -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 an i3 spin for others arm,aarch64 based
devices that can output display, but may not be able to have enough
accelerated desktop capabilities. See:
