this is with kernel 6.10.2
I have these options set on the boot command line:
isolcpus=0,1,2 nohz_full=1,2 rcu_nocbs=1,2
$ ps -eo pid,cpuid,comm | grep rcuog
18 3 rcuog/0
38 0 rcuog/2
I do not understand why a rcuog task is spawn for cpu0.
I would have expected to have one for cpu1.
I do have a
31 3 rcuos/1
I am not familiar enough with rcu to know what rcuos is for.
the absence of of rcuog/1 is causing rcu_irq_work_resched() to raise an
interrupt every 2-3 seconds on cpu1.
I am currently reading rcu/tree_nocb.h to try to make sense of what I
am seeing but I am pinging the rcu list just in case what I am seeing
would be immediately obvious to one of you...
thank you,
