Date: Tue, 28 Apr 2015 11:53:32 +0530 From: Shilpasri G Bhat <shilpa.bhat@...ux.vnet.ibm.com> To: linuxppc-dev@...abs.org, linux-kernel@...r.kernel.org Cc: Shilpasri G Bhat <shilpa.bhat@...ux.vnet.ibm.com> Subject: [PATCH v2 0/2] powernv: cpufreq: Report frequency throttle by OCC 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.
