H A Dintel_uncore_frequency_scaling.rst15 The uncore can consume significant amount of power in Intel's Xeon servers based
17 performance, SoCs have internal algorithms for scaling uncore frequency. These
18 algorithms monitor workload usage of uncore and set a desirable frequency.
20 It is possible that users have different expectations of uncore performance and
24 change to uncore frequency. Also, users may have workloads which require
25 different core and uncore performance at distinct phases and they may want to
26 use both cpufreq and the uncore scaling interface to distribute power and
32 To control uncore frequency, a sysfs interface is provided in the directory:
36 uncore scaling control is per die in multiple die/package SoCs or per
