#13Maybe I'm missing the relevant nexus between Linux, Open Source, and RISC-V, but I'm pretty sure BOOM [1] was already running Linux ~2 years ago. [1] https://github.com/ucb-bar/riscv-boom
BOOM is built on top of rocket-chip, both going back to 2011-2012 at Berkeley. The rocket-chip devs graduated Berkeley and started SiFive.
SiFive still use, update, and commit back to the rocket-chip code base and have spent resources on verifying the rocket-chip code base and on integrating other industry IP into their branch of rocket-chip to fit their costumers' needs.

Mad props to them. That's impressive and very community-minded.

#15Not open. Hardware design is closed and only for sale as a netlist.

All this is manual work done on top of a netlist generated usin…
Also they resell IP that is not theirs to give away, sadly. They are working on putting this chip in workstation class hardware, and when they do it will support PCIe, DDR4, USB3, etc. using off the shelf solutions they have licensed and integrated.
I hope that over time they, or partners, or others, will develop open source alternatives to these IP blocks. So that we can gradually increase the level of openness

Will this all be on a SOC? Are these plans public?
It'd be great to get some single board computers on the market based on this architecture...
