If you are using isolcpus in grub you need to use "cpu_chrt fifo 1" option in this script, other wise everything will run on the first core only.

Might be worth updating the docs as i just came across this issue.

Thanks. Do you mind opening PR? In general usage of isolcpus is not advised as it does not bring big benefits.

so, if we use isocpus we have to set # cpu_chrt fifo 1
I'll test this in a few days when I get some free time
