An Intel-specific plug-in for limiting the maximum and minimum uncore frequency.
The options [option]`max_freq_khz`, [option]`min_freq_khz` correspond to
`sysfs` files exposed by Intel uncore frequency driver. Their values can be
specified in kHz or as a percentage of their configurable range.
.Limiting maximum uncore frequency
====
----
[uncore10]
type=uncore
devices=uncore10
max_freq_khz=4000000
[uncore_all]
type=uncore
max_freq_khz=90%
----
Using this options *TuneD* will limit maximum frequency of all uncore units
on the Intel system to 90% of the allowable range. Except uncore10 which
maximum frequency limit will be set to 4 GHz.
