[did not reach linux-pm as I sent to wrong address, sorry for duplicates] The inspiration for this patch series is the N9 CPU frequency boost upon input events: http://www.spinics.net/lists/cpufreq/msg00667.html and the related changes in git://codeaurora.org/kernel/msm.git tree. Those patches modify the ondemand cpufreq governor. This patch series adds minimum and maximum CPU frequency as PM QoS parameters and modifies the cpufreq core to enforce the PM QoS limits. There is also an example module for boosting the frequency upon input events. I've been testing these changes against Ubuntu 3.2 kernel on a Dell E6420 with the ACPI cpufreq driver. The patches are against linux-next/master, compile tested against it.
