Some server users set limits on the uncore frequency using MSR 620H, while running latency sensitive workloads. Here uncore frequency controls RING/LLC(last-level cache) clocks. But MSR control is not always possible from the user space, so this driver provides a sysfs interface to set max and min frequency limits. This MSR 620H is a die scoped in multi-die system or package scoped in non multi-die systems. When this driver is loaded, a new directory is created under /sys/devices/system/cpu. For example on a two package Skylake server: $cd /sys/devices/system/cpu/intel_uncore_frequency $ls package_00_die_00 package_01_die_00 $ls package_00_die_00 max_freq_khz min_freq_khz initial_max_freq_khz initial_min_freq_khz $grep . * max_freq_khz:2400000 min_freq_khz:1200000 initial_max_freq_khz:2400000 initial_min_freq_khz:1200000 Here, initial_max_freq_khz and initial_min_freq_khz are read only attributes to show power up or initial values of max and min frequencies respectively. Other attributes are read-write, so that users can modify. Signed-off-by: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com> Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com>
