Pretty sure not even RISC-V is "open source hardware", in a meaningful way, unfortunately. There's a lot more to building a platform than the instruction set of the CPU. I've yet to see anyone building an open source hardware platform using RISC-V.. I would be thrilled to be proven wrong, so please do if you can!
- snvzz 8y agolowrisc and pulpino are just that (SoC and microcontroller respectively) There's also a few open CPU core efforts, but most relevant are perhaps Rocket, the reference implementation (single-issue in-order) and boom (out-of-order), a performance oriented implementation.
