This cpupower second update for Linux 6.12-rc1 consists of a fix
and a new feature.
-- adds missing powercap_set_enabled() stub function
-- adds SWIG bindings files for libcpupower
SWIG is a tool packaged in Fedora and other distros that can generate
bindings from C and C++ code for several languages including Python,
Perl, and Go.
These bindings allows users to easily write scripts that use and extend
libcpupower's functionality. Currently, only Python is provided in the
makefile, but additional languages may be added if there is demand.
Note that while SWIG itself is GPL v3+ licensed; the resulting output,
the bindings code, is permissively licensed + the license of the .o
files. Please see the following for more details.

Provide a definition for metadata that allows reading DC6 residency
counter via PMT and exposes it as a builtin counter.
Note that this residency counter is updated and read via
entirely different mechanisms vs the MSR-based residency counters.
On MTL processors, there are times when Die%c6 will report above 100%.

Allows users to read Intel PMT (Platform Monitoring Technology)

user has to supply the necessary information to find and correctly
display the requested counter.

Merge more cpupower utility changes for 6.11-rc1 from Shuah Khan:
"This cpupower second update for Linux 6.11-rc1 consists of
-- fix to install cpupower library in standard librray intall
location - /usr/lib
-- disable direct build of cpupower bench as it can only be
built from the cpupower main makefile."
* tag 'linux-cpupower-6.11-rc1-2' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/shuah/linux:
cpupower: fix lib default installation path
cpupower: Disable direct build of the 'bench' subproject
This version addresses one issue:
- Fix updating TRL MSR after SST-TF is disabled in auto mode.
Signed-off-by: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com>
When SST-TF is disabled in auto mode, the performance is getting
limited.
This is caused by wrong programming of Turbo Ratio Limit (TRL) MSR.
This MSR always accepts the frequency ratio in 100 MHz unit. When the
TPMI is sending TRL in 1 MHz unit, change to 100 MHz, before updating
TRL MSR.

Invocation the tool built with the default settings fails:
$ cpupower
cpupower: error while loading shared libraries: libcpupower.so.1: cannot
open shared object file: No such file or directory
The issue is that Makefile puts the library to "/usr/lib64" dir for a 64
bit machine. This is wrong. According to the "File hierarchy standard
specification:
https://en.wikipedia.org/wiki/Filesystem_Hierarchy_Standardhttps://refspecs.linuxfoundation.org/FHS_3.0/fhs-3.0.pdf
"/usr/lib<qual>" dirs are intended for alternative-format libraries
(e.g., "/usr/lib32" for 32-bit libraries on a 64-bit machine (optional)).
The utility is built for the current machine and doesn't handle
'CROSS_COMPILE' and 'ARCH' env variables. It also doesn't change bit
depth. So the result is always the same - binary for x86_64
architecture. Therefore the library should be put in the '/usr/lib'
dir regardless of the build options.
This is the case for all the distros that comply with the
'File Hierarchy Standard 3.0" by Linux Foundation. Most of the distros
comply with it. For example, one can check this by examining the
"/usr/lb64" dir on debian-based distros and find that it contains only
"/usr/lib64/ld-linux-x86-64.so.2". And examine that "/usr/lib" contains
both 32 and 64 bit code:
find /usr/lib -name "*.so*" -type f | xargs file | grep 32-bit
find /usr/lib -name "*.so*" -type f | xargs file | grep 64-bit
Fix the issue by changing library destination dir to "/usr/lib".

Execution of the 'make' command in the 'bench' subfolder causes the

make: *** [Makefile:21: cpupower/build//parse.o] Error 127
make: *** [Makefile:21: cpupower/build//system.o] Error 127
The makefile uses variables defined in the main project makefile and it
is not intended to run standalone. The reason is that 'bench' subproject
depends on the 'libcpupower' library, see the 'compile-bench' target in
the main makefile.
Add a check that prevents standalone execution of the 'bench' makefile.

Commit 78464d7681 ("tools/power turbostat: Add columns for clustered
uncore frequency") introduced 'probe_intel_uncore_frequency_cluster()'
in a way which prevents printing uncore frequency columns if either of
the '-q' or '-l' options are used. Systems which do not have multiple
uncore frequencies per package are unaffected by this regression.
Fix the function so that uncore frequency columns are shown when either
the '-l' or '-q' option is used by checking if 'quiet' is true after
adding counters for the uncore frequency columns.

In some cases specifying the '-n' command line argument will cause
turbostat to fail. For instance 'turbostat -n 1' works fine; however,
'turbostat -n 1 -d' will fail. This is the result of the first call
to getopt_long_only() where "MP" is specified as the optstring. This can
be easily fixed by changing the optstring from "MP" to "MPn:" to remove
ambiguity between the arguments.
tools/power turbostat: option '-n' is ambiguous; possibilities: '-num_iterations' '-no-msr' '-no-perf'
Fixes: a0e86c90b8 ("tools/power turbostat: Add --no-perf option")

There is a type 'enum operation_mode_e' contains the display modes of
the 'monitor' subcommand. This type isn't used though, instead the
variable 'mode' is of a simple 'int' type.
Change 'mode' variable type from 'int' to 'enum operation_mode_e' in
