I make a point of periodically updating and checking for the continued functionality of all new packages I submit to Guix. There is a fair bit of RISC-V work I would like to do over the next years so I would have no problem extending this personal policy to these packages as well. > How much faster? Knowing nothing about RVVM, When I asked on > irc.libera.chat #riscv that was basically the question I got... No idea, but having done a fair bit of RISC-V development on emulators, I'm willing to take anything I can get XD > Worked around how? So, that turn of phrase was pretty arbitrary, but the sentiment I wished to communicate is that I doubt most developers need Linux to be tiny. I don't even understand *why* Linux needs to be shrunk for rvvm; perhaps to minimize the disk space or memory given to it? If that's the case, then the work-around would be to give it more disk and memory from the host. > Thinking a little more, from what I recall, the whole point of > fw_jump.bin is so that you can dynamically specify the payload at > runtime ... why do we need a separate fw_payload.bin created at > build-time, if you can just pass a (potentially custom) payload at > runtime? As mentioned in the cover letter, you can drop the opensbi patch if you like. I didn't think to test opensbi-generic before packaging this patched version, and figured "waste not; want not." However, rvvm does not work with any version of u-boot currently in Guix. Hope this helps with any concerns. Let me know if I need to make any changes to the patch(es). Thanks, Juli
