It subsumes it, similar to Dominik's ideas in "[RFC] Dynamic Frequency and Voltage Scaling Infrastructure" (on the cpufreq list). The idea is that you want scaling events to be generated by the kernel rather than only scaling on userland input. The paper (and Dominik's mail) give you some ideas of when and why... -Hollis -- PowerPC Linux IBM Linux Technology Center [unhandled content-type:application/pgp-signature] | ||||||||||||
