Architectures/RISC-V

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.

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.

Status January 2018 The second (interim) bootstrap of Fedora 27 was completed successfully. We are now waiting for glibc changes to go upstream before proceeding with the third/final bootstrap.

Status December 2017 We are currently doing an "interim bootstrap" of Fedora 27. This is practice for the third and hopefully final bootstrap in Feb 2018. Please read Architectures/RISC-V/Bootstrapping for more information about bootstrapping.

Status November 2017 Linux has support since 4.15. We are waiting for glibc to go upstream which is expected to happen in February 2018. At that point we will be re-bootstrapping the whole project using the final ABIs.

Status November 2016 The port supports about two thirds of the packages in Fedora 25, so it is quite complete and ready to use. Most important command-line programs just work (and even a few graphical ones). However if you are using your own hardware then you will need to supply a compatible kernel and bootloader and just use the Fedora userspace. Fedora/RISC-V does not support 32 bit or embedded hardware.
