Ariane RISC-V CPU
The lack of floating point and atomics is an "interesting" choice for a Linux-capable chip.  It might run Fedora[1], but would likely require kernel support for emulating floats (as the distro is compiled assuming hard floats) and of course without atomics would only be single core.  The README says they plan to add atomics.<p>At least it supports compressed instructions.  There are some actual chips about to be released without the C (compressed) extension, but Fedora and Debian are compiling everything assuming the C extension.<p>In Fedora news, just today we've got a bootable (but very minimal) RISC-V disk image[2] that you can run in qemu.<p>[1] <a href="https://fedoraproject.org/wiki/Architectures/RISC-V" rel="nofollow">https://fedoraproject.org/wiki/Architectures/RISC-V</a><p>[2] <a href="https://fedorapeople.org/groups/risc-v/disk-images/" rel="nofollow">https://fedorapeople.org/groups/risc-v/disk-images/</a>
