Hi Helge, It looks like this will always be a complex issue on RISC-V since there is such a variety of manufacturers. However I think the following would be the best approach.
First, if there is a uarch field, use that since it will describe the design of the cores present, such as Sifive's U74-MC which can be licensed to other manufacturers, in a similar way to ARM core IP. If there isn't a uarch field, try to use the "model name" field if it is present, since on the C910 this seems to replace the uarch field (C910 is a core). Finally, if neither of those fields exist, the isa field might be ok but I would add "unknown core" to the output. The letters at the end of the isa field indicate which instruction set extensions are present. (i for basic integer support, a for atomics, v for vector, etc) So it is useful info, but it is vendor-generic for the most part. -Alan
