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/ [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
