The Intel(R) Speed select technologies contains four features.
Performance profile:An non architectural mechanism that allows multiple
optimized performance profiles per system via static and/or dynamic
adjustment of core count, workload, Tjmax, and TDP, etc. aka ISS
in the documentation.
Base Frequency: Enables users to increase guaranteed base frequency on
certain cores (high priority cores) in exchange for lower base frequency
on remaining cores (low priority cores). aka PBF in the documenation.
Turbo frequency: Enables the ability to set different turbo ratio limits
to cores based on priority. aka FACT in the documentation.
Core power: An Interface that allows user to define per core/tile
priority.
There is a multi level help for commands and options. This can be used
to check required arguments for each feature and commands for the
feature.
To start navigating the features start with
$sudo intel-speed-select --help
For help on a specific feature for example
$sudo intel-speed-select perf-profile --help
To get help for a command for a feature for example
$sudo intel-speed-select perf-profile get-lock-status --help

To set frequency on specific cpus using cpupower, following syntax can
be used :
cpupower -c #i frequency-set -f #f -r
While setting frequency using cpupower frequency-set command, if we use
'-r' option, it is expected to set frequency for all cpus related to
cpu #i. But it is observed to be missing the last cpu in related cpu
list. This patch fixes the problem.

tools/power/acpi/.gitignore has the following entries:
acpidbg
acpidump
ec
They are intended to ignore the following build artifacts:
tools/power/acpi/acpidbg
tools/power/acpi/acpidump
tools/power/acpi/ec
However, those .gitignore entries are effective not only for the
current directory, but also for any sub-directories.
So, from the point of .gitignore grammar, the following check-in
directories are also considered to be ignored:
tools/power/acpi/tools/acpidbg
tools/power/acpi/tools/acpidump
tools/power/acpi/tools/ec
As the manual gitignore(5) says "Files already tracked by Git are not
affected", this is not a problem as far as Git is concerned.
However, Git is not the only program that parses .gitignore because
.gitignore is useful to distinguish build artifacts from source files.
For example, tar(1) supports the --exclude-vcs-ignore option. As of
writing, this option does not work perfectly, but it intends to create
a tarball excluding files specified by .gitignore.
The issue can be prevented by prefixing the pattern with a slash; the
leading slash means the specified pattern is relative to the current
directory.
Do that for the "include" directory too for consistency and extra
safety.

Pull x86 MDS mitigations from Thomas Gleixner:
"Microarchitectural Data Sampling (MDS) is a hardware vulnerability
which allows unprivileged speculative access to data which is
available in various CPU internal buffers. This new set of misfeatures
has the following CVEs assigned:
CVE-2018-12126 MSBDS Microarchitectural Store Buffer Data Sampling
CVE-2018-12130 MFBDS Microarchitectural Fill Buffer Data Sampling
CVE-2018-12127 MLPDS Microarchitectural Load Port Data Sampling
CVE-2019-11091 MDSUM Microarchitectural Data Sampling Uncacheable Memory
MDS attacks target microarchitectural buffers which speculatively
forward data under certain conditions. Disclosure gadgets can expose
this data via cache side channels.
Contrary to other speculation based vulnerabilities the MDS
vulnerability does not allow the attacker to control the memory target
address. As a consequence the attacks are purely sampling based, but
as demonstrated with the TLBleed attack samples can be postprocessed
successfully.
The mitigation is to flush the microarchitectural buffers on return to
user space and before entering a VM. It's bolted on the VERW
instruction and requires a microcode update. As some of the attacks
exploit data structures shared between hyperthreads, full protection
requires to disable hyperthreading. The kernel does not do that by
default to avoid breaking unattended updates.
The mitigation set comes with documentation for administrators and a
deeper technical view"

The package power can also be read from an MSR. It's not clear exactly
what is included, and whether it's aggregated over all nodes or
reported separately.
It does look like this is reported separately per CCX (I get a single
value on the Ryzen R7 1700), but it might be reported separately per-
die (node?) on larger processors. If that's the case, it would have to
be recorded per node and aggregated for the socket.
Note that although Zen has these MSRs reporting power, it looks like
the actual RAPL configuration (power limits, configured TDP) is done
through PCI configuration space. I have not yet found any public
documentation for this.

Based on the Open-Source Register Reference for AMD Family 17h
Processors Models 00h-2Fh:
https://support.amd.com/TechDocs/56255_OSRR.pdf
These processors report RAPL support in bit 14 of CPUID 0x80000007 EDX,
and the following MSRs are present:
0xc0010299 (RAPL_PWR_UNIT), like Intel's RAPL_POWER_UNIT
0xc001029a (CORE_ENERGY_STAT), kind of like Intel's PP0_ENERGY_STATUS
0xc001029b (PKG_ENERGY_STAT), like Intel's PKG_ENERGY_STATUS
A notable difference from the Intel implementation is that AMD reports
the "Cores" energy usage separately for each core, rather than a
per-package total. The code has been adjusted to handle either case in a
generic way.
I haven't yet enabled collection of package power, due to being unable
to test it on multi-node systems (TR, EPYC).

turbostat executes on CPUs in "topology order".
This is an optimization for measuring profoundly idle systems --
as the closest hardware is woken next...
Fix a typo that was added with the sub-die-node support,
that broke topology ordering on multi-node systems.

turbostat failed to return a non-zero exit status even though the
supplied command (turbostat <command>) failed. Currently when turbostat
forks a command it returns zero instead of the actual exit status of the
command. Modify the code to return the exit status.

Pull more power management updates from Rafael Wysocki:
"These are mostly fixes and cleanups on top of the previously merged
power management material for 5.1-rc1 with one cpupower utility update
that wasn't pushed earlier due to unfortunate timing.
Specifics:
- Fix registration of new cpuidle governors partially broken during
the 5.0 development cycle by mistake (Rafael Wysocki).
- Avoid integer overflows in the menu cpuidle governor by making it
discard the overflowing data points upfront (Rafael Wysocki).
- Fix minor mistake in the recent update of the iowait boost
computation in the intel_pstate driver (Rafael Wysocki).
- Drop incorrect __init annotation from one function in the pxa2xx
cpufreq driver (Arnd Bergmann).
- Fix the operating performance points (OPP) framework initialization
for devices in multiple power domains if only one of them is
scalable (Rajendra Nayak).
- Fix mistake in dev_pm_opp_set_rate() which causes it to skip
updating the performance state if the new frequency is the same as
the old one (Viresh Kumar).
- Rework the cancellation of wakeup source timers to avoid potential
issues with it and do some cleanups unlocked by that change (Viresh
Kumar, Rafael Wysocki).
- Clean up the code computing the active/suspended time of devices in
the PM-runtime framework after recent changes (Ulf Hansson).
- Make the power management infrastructure code use pr_fmt()
consistently (Joe Perches).
- Clean up the generic power domains (genpd) framework somewhat
(Aisheng Dong).
- Improve kerneldoc comments for two functions in the cpufreq core
(Rafael Wysocki).
- Fix typo in a PM QoS file description comment (Aisheng Dong).
- Update the handling of CPU boost frequencies in the cpupower
utility (Abhishek Goel)"

Greg pointed out that speculation related bit defines are using (1 << N)
format instead of BIT(N). Aside of that (1 << N) is wrong as it should use
1UL at least.
Clean it up.

cpufreq driver creates sysfs file "scaling_boost_frequency" for platforms
which support boost frequency. Cpupower now prints boost frequencies
separately. For few x86 vendors who already have different way to get boost
frequency, will continue to use the existing logic. Rest of the platforms
will rely on "scaling_boost_frequency" file to display boost frequency.
