I don't know anything about perf, so I could be asking a really silly
question here, but how come riscvN-linux- has been omitted here?
The kernel.org toolchains [1] are prefixed that way, although I noticed
in your v1 that you'd seemingly duplicated the arm64 patterns, so I am
curious as to whether the omission is intentional.
Cheers,
Conor.
