This is largely based on Guo's work and Leonardo reviews at [1].

Guo, could/should this have your Co-developed-by:/Signed-off-by:?

(disclaimer: I haven't looked at the last three patches of this submission
with due calm and probably won't before ~mid-July...)

Link: https://lore.kernel.org/linux-riscv/20231225125847.2778638-1-guoren@kernel.org/ (local) [1]

There seems to be a distinct lack of experimental results, compared to the
previous/cited submission (and numbers are good to have!!  ;-)). Maybe Guo
/others can provide some? to confirm this is going in the right direction.

  Andrea
