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.

Topics

Installing - How to download, install and run Fedora/RISC-V.
Hardware - Information about supported and experimental Fedora/RISC-V hardware

Get in touch

Most of the people working on the effort hang out in Fedora RISC-V Matrix room. Come say hello :)

Follow (and post to!) #risc-v-sig on Fedora Discussion! (If you prefer, you can follow this tag by email.)

News

Jan 2025 Fedora 41 images are now available.

Outdated information

Over time, we have accumulated lots of information on this wiki. A large chunk of it, while useful at the time, is not really relevant to anyone looking to run Fedora on RISC-V today, or contribute to the porting effort. To avoid any confusion, all outdated material has been moved to the Archive.

+Over time, we have accumulated lots of information on this wiki.

To avoid any confusion, all outdated material has been moved to the [[Architectures/RISC-V/Archive|Archive]].
-The stage3 environment can be built from source or you can download a snapshot binary image.  See above for links to git etc.
-Pick a package which:
-* has very few dependencies
-* is written in C or C++
-* is part of Fedora @Core
-Grab the source RPM from [http://koji.fedoraproject.org/koji/ Koji].
-Copy the source RPM into the stage3 disk image.  The disk image <b>must not</b> be running when you do this:
- virt-copy-in -a stage3-disk.img the_package.src.rpm /var/tmp/
-Boot the disk image in qemu:
- make boot-stage3-in-qemu
-Inside the VM you can now "install" the source RPM, which makes it available under <code>/rpmbuild</code>:
- rpm -i /var/tmp/the_package.src.rpm
- cd /rpmbuild/SPECS
-You may need to disable hardened build by adding:
- %undefine _hardened_build
-to the spec file.  Use <code>vim</code> to edit files.
-You can now try building the package:
- rpmbuild -ba the_package.spec --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 <code>/rpmbuild</code> inside the VM.  sync and shut down the VM, then do:
- virt-copy-out -a stage3-disk.img /rpmbuild ./
-and the files will be downloaded to ./SRPMS and ./RPMS in the current directory.  Note: Keep the source RPM too, especially if you modified it.
-Add notes to the section below.  Also come to <code>#fedora-riscv</code> and discuss where to put your built packages.
-== Notes on packages built so far ==
-<i>The list of packages in this section was constantly out of date, so I deleted it</i>
-To see the packages which have been built so far, look in the git repo.  If you are planning to port another package, please ping us on <code>#fedora-riscv</code> first, just to make sure that two people don't do overlapping work.
-=== "all-recursive" bug in make ===
- Making all in .
- Makefile:742: recipe for target 'all-recursive' failed
-Added this to the spec file as a workaround:
- sed 's/\$(am__cd) \$\$subdir \&\&/cd $$subdir ;/g' -i Makefile.in
-=== debugedit missing ===
-Use <code>%global debug_package %{nil}</code> (temporarily for stage3, in stage4 we will attempt to build the debuginfo packages).
-=== bugs about locking, random "Permission denied" ===
-Update to the latest riscv-gnu-toolchain and rebuild the kernel from the repo.  All known locking bugs have been fixed.
