Thanks Daniel! I forgot about your work in this area. As I have
responded in some other email in this thread, we might start
from a new small governor and than others can contribute.

Even this small governor that Kajetan showed me performs really
good on pixel6.

Do you have others ARM64 platforms to compare with ?


Yes we have, also some older platforms (~10years now, which
would be nice to check how they would perform).
We also have a big arm64 server to give it a try there. So those results
will be available with the new patch when we decide to go the new
governor.
