Linux

Linux and related tools are - for the most part - already in the upstream repositories of the respective projects. As noted on the Debian RISC-V wiki (with some updates):

• binutils: upstreamed (2.28 is the first release with RISC-V support)
• gcc: upstreamed (7.1 is the first release with RISC-V support)
• glibc: upstreamed (2.27 is the first release with RISC-V support)
• linux kernel: upstreamed (the architecture core code went into kernel 4.15; kernel 4.19 contains all drivers necessary for booting a simulated system to userland)
• gdb: upstreamed in master (in the release process)
• qemu: upstreamed (2.12 is the first release with RISC-V support)

Linux-enabled platforms currently described in the Getting Started Guide include:

• SiFive HiFive Unleashed
• LiteX SoC with VexRiscv CPU running on the Future Electronics Avalanche board with a Microsemi PolarFire FPGA or in the Renode simulation framework

There is also a generic QEMU 64-bit RISC-V simulation target running Linux.

Debian, Fedora, and openSUSE ports are also available, for more information see:
