If there is a riscv64 server/workstation out there that I can buy, today, I would love to order one.
They're the "closest", but not remotely close.
AFAICT all the SiFive products that are available to purchase and have workstation-ish amounts of RAM require boot blobs. I would be happy to be wrong about this.

Apparently there was a very limited run of dev boards for which no blobs are needed, and then they promptly discontinued that product and replaced it with a (confusingly-similarly-named) blobbified product that you can pre-order via mouser (listed as "backordered, no ETA"). This product is already marked EOL which is not encouraging.

That board's firmware is not open-source at all. See the link in my previous comment.
> Zero idea what blobs this requires.
You've stumbled into the wrong thread, my friend. This thread is about open-source firmware. The stuff you're hyping does not deliver that.
I am definitely not hyping anything, least of all SiFive.
This subthread started with the need for RISC-V workstations, I simply pointed out the closest thing to one of those. Of course I didn't mention the firmware situation, which was a mistake, but I also didn't know about the situation.
