I notice that we don't generate similar events for cpufreq... what are the performance implications from firing off udev (which isn't free) every time we scale the CPU frequency? It feels like this might be disruptive, especially with a governor like ondemand which responds to system load. [unhandled content-type:application/pgp-signature] | |
