I guess I should have sent this to you too. Only sent to linux-pm. 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. --Antti Alex Frid (1): PM QoS: Simplify PM QoS expansion/merge Antti P Miettinen (5): PM QoS: Add CPU frequency min/max as PM QoS params cpufreq: Export user_policy min/max cpufreq: Preserve sysfs min/max request cpufreq: Enforce PM QoS min/max limits input: CPU frequency booster drivers/cpufreq/cpufreq.c | 57 +++++++++++++- drivers/input/Kconfig | 9 ++ drivers/input/Makefile | 1 + drivers/input/input-cfboost.c | 174 +++++++++++++++++++++++++++++++++++++++++ include/linux/pm_qos.h | 19 ++++- kernel/power/qos.c | 55 ++++++++++---- 6 files changed, 293 insertions(+), 22 deletions(-) create mode 100644 drivers/input/input-cfboost.c -- 1.7.4.1 -- To unsubscribe from this list: send the line "unsubscribe cpufreq" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
