However, I noticed that most kernel threads use the affinity mask 0xff. I can change this by using “taskset”. However, I am wondering if there is mechanism that forces the kernel to consider the value of “isolcpus” also for kernel threads.
not that I am aware of. There are a few per-CPU threads which have to stay the way they are. I would have expected that others like kworker/u* respect the isol CPUs and stay away.
Best regards Mathias
