nohz_full
confusingly also helps with power usage… if the cpu doesn’t have anything to run, no point waking it up with a scheduler-tick IPI… but also no point trying to run the scheduler if a core is peaking with a single task… With nohz
the kernel overheard basically ceases to exist for a task while the it is running. (Thought the overhead just moves to non-nohz cpu cores)
A dum question: if both candidates are unable to function, then what happens? (Trump for his crimes, Biden for getting dementia…)
Meanwhile in Finland: the Finnish version of “build the wall”:
The bill needs 5/6 parliamentary approval and politicians are already sweating over it because it touches too many international treaties + constitution. Debate is mostly: is it ready yet? is it ready yet? is it ready yet? (While the committees checking the bill are getting more uneasy by the bill’s content…)
