Notes:

The order of authors with > 30 commits listed here is sorted by contributions
from high to low through ``git log --no-merges $@ | grep Author: | \
cut -d: -f2 | cut -d\< -f1 | sort | uniq -c | sort -n -r''. The list of minor
contributors is currently unsorted and contains people who have contributed
code ``in some way'' (e.g. on the upstream or maintenance repositories), either
through Git or email.

Note that we have taken over the maintenance and further development of Herbert
Haas' mausezahn [ˈmauzəˌtsa:n] utility after he passed away in 2011. There were
no Git commit statistics available from the import of his project. The project
is currently in a staging area, but will be fully integrated soon. (*)

implement what's on the TODO file and show an ongoing, active interest in
supporting netsniff-ng. What's in it for you? If you ever come to Switzerland,
you get a free beer on Daniel and you can meet some great people involved in
this project. ;)

<div class='commit-subject'>cpufreq: intel_pstate: Disable energy efficiency optimization</div><div class='commit-msg'>Some Kabylake desktop processors may not reach max turbo when running in
HWP mode, even if running under sustained 100% utilization.

This occurs when the HWP.EPP (Energy Performance Preference) is set to
"balance_power" (0x80) -- the default on most systems.

It occurs because the platform BIOS may erroneously enable an
energy-efficiency setting -- MSR_IA32_POWER_CTL BIT-EE, which is not
recommended to be enabled on this SKU.

On the failing systems, this BIOS issue was not discovered when the
desktop motherboard was tested with Windows, because the BIOS also
neglects to provide the ACPI/CPPC table, that Windows requires to enable
HWP, and so Windows runs in legacy P-state mode, where this setting has
no effect.

Linux' intel_pstate driver does not require ACPI/CPPC to enable HWP, and
so it runs in HWP mode, exposing this incorrect BIOS configuration.

There are several ways to address this problem.

First, Linux can also run in legacy P-state mode on this system.
As intel_pstate is how Linux enables HWP, booting with
"intel_pstate=disable"
will run in acpi-cpufreq/ondemand legacy p-state mode.

Or second, the "performance" governor can be used with intel_pstate,
which will modify HWP.EPP to 0.

Or third, starting in 4.10, the
/sys/devices/system/cpu/cpufreq/policy*/energy_performance_preference
attribute in can be updated from "balance_power" to "performance".

Or fourth, apply this patch, which fixes the erroneous setting of
MSR_IA32_POWER_CTL BIT_EE on this model, allowing the default
configuration to function as designed.
