make boot-stage3-in-spike
: Tracker bug for all issues which affect Fedora on RISC-V
 
Inside the VM, you can now try building the package:
 
cd /var/tmp
rpmbuild --rebuild the_package.src.rpm \
    --define "debug_package %{nil}"
 
If it builds successfully, brilliant!  More usually this will require many cycles of debugging and fixing things. Removing dependencies or parts of the spec file is an option for these stage3 builds.
 
If you get a build, it will be in /rpmbuild inside the VM.  sync and shut down the VM, then do:
 
virt-copy-out -a stage3-disk.img /rpmbuild/RPMS .
 
and the files will be downloaded to ./RPMS/ in the current directory.
 
Add notes to the section below. Also come to #fedora-riscv and discuss where to put your built packages.

The build took over 24 hours, but it got surprisingly far. Unfortunately it failed while creating the locale files. Actually it failed half way through the locales in a very non-specific way. Needs a lot more investigation and time. I might try to find a faster machine first.

RISC-V (pronounced "RISC Five") is an open source instruction set architecture (ISA). This project, informally called Fedora/RISC-V, aims to provide a complete Fedora experience on the RISC-V (64 bit, RV64GC) architecture.

News

Please contact people at the RISC-V SIG if you want to know the latest status.

May 2024 We're starting a Special Interest Group! See the RISC-V SIG for more details.

May 2024 PLCT have releases a new repo for Fedora RV64 OCI image, currently F39 and F40 is avaliable. https://hub.docker.com/r/fedorariscv/base

Jun 2023 A new Fedora 38 OCI image for riscv64 is available.

May 2023 T-Head platform (Sipeed LicheePi 4A) description and installation how-to at Architectures/RISC-V/T-Head

Jan 2022 PLCT Lab have another new koji build system for Riscv64.

Oct 2021 Community member made a Fedora based BSP image for Allwinner D1 Nezha board. The information is available at Architectures/RISC-V/Allwinner. Note: Allwinner D1 is NOT officially supported by Fedora yet.

May 2018 A Koji build system instance is now building Fedora packages.

February/March 2018 Stage4 disk images are available. These are bootable in qemu and let you try out Fedora/RISC-V. Make sure you read the readme.txt file first. The development environment is quite complete with GCC 7.3.1, Perl 5.26, Python 2 and 3, git, systemd, various editors including vi and emacs, many -devel packages, and some X11 packages. It will be enough for most developers to start porting their software to RISC-V. The main missing things at the moment are Ruby, Java and Gtk 3.

Status January/February 2018 The third and hopefully final bootstrap of Fedora 27 has started. Please follow progress or try building it yourself via this git repository. Expected timelines are: 1-2 weeks until stage 3 disk images are available, 1-2 months until stage 4 pristine RPM-built disk images are available, 2 months until we are autobuilding regular Fedora packages, 3-6 months until we have koji-shadow functionality.
