hi all
i noticed, that the cpu frequency scaling doesn't react on cpu load caused by pd. even if i have a constant high load - for instance when running several hundred [osc~]s - the cpu frequency stays at the lowest value of 800 MHz. i need to run another program, such as 'yes' or 'burnMMX' in order to trigger the scaling to set the frequency to the maximum of 2401000 MHz. so far i only noticed this behaviour with pd. other programs don't seem to 'fool' frequency scaling.
specs: pd 0.41.4 running in -rt -jack mode 2.6.24-21-rt (from ubuntu hardy) Intel Core 2 Duo CPU T8300 @ 2.40GHz scaling_governor: on_demand (default)
i know, that it is most likely not a direct pd problem, but probably some other pd-linux users encountered a similar behaviour. as a workaround, i currently manually switch the scaling_governor to 'performance', when i am in a 'performative' situation. i wonder, if there is a real fix for that problem.
