From: "Gautham R. Shenoy" <e...@linux.vnet.ibm.com> Hi,
On IBM POWERNV platforms[1], presently we do not report the current operating frequency of the processor through the sysfs interface "cpuinfo_cur_freq" since the cpu frequency driver[1] has not implemented the ->get(unsigned int cpu) method. Fix this by implementing the ->get(unsigned int cpu) method which will report the frequency corresponding to the pstate_id on PMSR on "cpu". Also, export the nominal frequency of the processor through the sysfs interface "cpuinfo_nominal_freq" by defining it as a driver attribute. The patch series depends on the cpu-frequency driver patch-series[1]. [1] http://comments.gmane.org/gmane.linux.ports.ppc.embedded/67905 Thanks and Regards gautham.
