This patchset intends to add frequency throttle reporting mechanism to powernv-cpufreq driver when OCC throttles the frequency. OCC is an On-Chip-Controller which takes care of the power and thermal safety of the chip. The CPU frequency can be throttled during an OCC reset or when OCC tries to limit the max allowed frequency. The patchset will report such conditions so as to keep the user informed about reason for the drop in performance of workloads when frequency is throttled. Changes from v3: - Rebased on top of 4.2-rc1 - Minor changes in patch 2,3,4,6 this does not change the functionality of the code - 594fcb9ec9e powerpc/powernv: Expose OPAL APIs required by PRD interface , this patch fixes the build error due to which this series was initially dropped ERROR: ".opal_message_notifier_register" drivers/cpufreq/powernv-cpufreq.ko] undefined!
I have already Acked v3 of this and that applies to this one as well.. -- viresh
