SubjectRe: [PATCH 2/2] riscv: Add vector ISA support
Thx Anup,

The purpose of the patch is to talk about abi for linux & libc.

The most confused me is how max vlen (128/256/512/1024 ???), we should
put it into sigcontext. I need people's suggestions, thx.

Anyone help to review the patch are very helpful and we could
co-developed together, Thx
