Interesting. Debian is supporting RV64GC whereas Ubuntu is targeting RVA23.
To someone not familiar with the RISC-V architecture, what that difference means?
Risc-V has a base specification and then a bunch of extensions. RV64G is almost as basic as you can get. It has 64-bit registers as opposed to RV32s 32-bit ones and it has floating point instructions. C adds compressed instructions which are good for keeping more code in cache.
RVA23 is a "profile" which includes a lot more extensions. 56-bit virtual memory, vector processing, and hypervisor mode being the big ones. I don't think anybody has come out with a RVA23 compliant piece of silicon yet.
So Debian is supporting existing hardware and Ubuntu has ditched support for the existing processors and is supporting what is currently yet to appear.
