The default values for spa make it really easy to lock up the system.
Is there a module to autotune these values according to cpu/mem/ctxt
performance?
Jake Moilanen had a genetic algorithm autotuner for Zaphod at one time
which I believe he ported over to PlugSched
Would this be a load-adaptive dynamic tuner?
Yes.
What I meant was a lock-preventive static tuner. Something that would take
hw-latencies into account at boot and set values for non-locking console
operation.
I'm not sure what you mean here. Can you elaborate?
I could generate a patch to gather the statistic again and make them
available via /proc if you would like to try a user space version of
Jake's work (his was in kernel).
That would be great!
OK, I'll put it on my "to do" list.
