And if not Ludovic, who'd be a good mentor for this item (and has time to spend on it)? Manolis has worked on porting to a different kernel, Efraim has worked on porting to another architecture. >> With regards to RISC-V porting: a question I don't dare asking in >> public because it's answer could be too obvious: is the porting >> possible without owning any real RISC-V hardware? > > I know very little about RISC-V, but I suppose QEMU could help (and most > of the porting work is about getting cross-compilation right.) > >> I think at this point I know enough in Guix to port it to another >> architecture and would apply for this when the GSoC student >> applications are open, depending on your reply. > > Cool.

Looking at the timeline on the Google GSoC website it falls into my next semester where I can't tell you right how many hours I have available. Students applications period starts in March, so that gives me enough time to look into how porting without owning the hardware works, refreshing my memory on it (recently I've read about slow but native compiling of ARM on qemu). As Ludovic wrote, and by my understanding of porting, it will mostly cover bootstrap + ideally having a compiled (better: functional) Guix on RISC-V? -- ng0 :: https://ea.n0.is A88C8ADD129828D7EAC02E52E22F9BBFEE348588 :: https://ea.n0.is/keys/
