Have you got some figures which shows the improvement of the responsivness compared to other governor like the ondemand one ? That could be interesting to test interactive governor with cpufreq-bench and compare the results with ondemand ?
I don't have any numbers handy, but no doubt the governor brings some improvements which you can see on a real device.
Anyway, the point of sending out these RFC patches was to get a technical review of the approach, because there's no much point in pushing the code that isn't acceptable on technical merits, no matter how better numbers it might give.
And scheduler folks aren't happy on the whole approach, so I guess we should go back to the drawing board. :-)
Thanks,
p.s. Sure, in the end we'll have to measure 'interactive' vs. 'ondemand' vs. 'newapproach'. And maybe now it's time to actually measure 'interactive' governor in numbers... I'll get back to this thread when I get the numbers.
