[Xen-devel] [PATCH 1/3] Update cpufreq aperf and mperf read, so that it can be used by both ondemand gov and user program
Update cpufreq aperf and mperf read, so that it can be used by both ondemand gov and user program. Current __get_measured_perf read aperf and mperf MSR and then clear them for the sake of ondemand governor. This solution block user program to get aperf and mperf on their purpose. In this patch, it no longer clear aperf and mperf MSR, so that it can be used by both ondemand gov and user program.
