Again, I think Jes or others can provide more information.
Sagi, I believe Jes is not trying to argue about what initial affinity
values you give to the driver, We have a very critical regression that
is afflicting Live systems today and common tools that already exists
in various distros, such as irqblanace which solely depends on
smp_affinity sysfs entry which is now not write-able due to this
regression. please see https://github.com/Irqbalance/irqbalance/blob/ma
ster/activate.c
Some users would like to have thier network traffic handled in some
cores and free up other cores for other purposes, you just can't take
that away from them.
If revereting mlx5 patches would solve the issue, I am afraid that is
the solution i am going to go with, until the regression is fixed.
Well, I completely agree with you Saeed, If this is causing regression
for mlx5 users and we can't find a way for managed interface to expose
this knob to userspace, I don't see any other choice as well.
