cpupower: Improve Python binding's Makefile

2025-07-01T16:58:00+00:00

Add a few build variables to make it easier for distributions to package the bindings. Allow current variables to be overwritten by environment variables that are passed to make.

cpupower: change binding's makefile to use -lcpupower

2025-05-02T19:52:51+00:00

Originally I believed I needed the .o files to make the bindings. The linking failed due to a missing .so link in Fedora or by using make install-lib from the cpupower directory. Amend the makefile and the README. Big thanks to Wander Lairson Costa for the help. Link: https://lore.kernel.org/r/20250429204711.127274-1-jwyatt@redhat.com Signed-off-by: "John B.

pm: cpupower: Add install and uninstall options to bindings makefile

2024-12-20T16:12:07+00:00

Installs the .so and .py files generated by SWIG to system's site packages directory. This allows the Python bindings to be used system wide. This commit also includes documentation on setting up and installing the Python bindings. Link: https://lore.kernel.org/r/20241219012606.38963-1-jwyatt@redhat.com Signed-off-by: "John B.

pm: cpupower: rename raw_pylibcpupower.i

2024-09-13T20:24:16+00:00

The raw_pylibcpupower.i is removed unexpectedly after 'make mrproper' We can reproduce the error by performing the following steps: cd linux-next make mrproper cd tools/power/cpupower/bindings/python make We will get an error message: make: *** No rule to make target 'raw_pylibcpupower.i', needed by 'raw_pylibcpupower_wrap.c'. Stop. The root cause: The *.i files are already used for pre-processor output files and the kernel removes all the *.i files by 'make mrproper'. That explains why the raw_pylibcpupower.i is removed by 'make mrproper'. To fix it, Follow John's suggestion to rename raw_pylibcpupower.i to raw_pylibcpupower.swg.

pm:cpupower: Add error warning when SWIG is not installed

2024-09-06T16:58:35+00:00

Add error message to better explain to the user when SWIG and python-config is missing from the path. Makefile was cleaned up and unneeded elements were removed. Suggested-by: Shuah Khan Signed-off-by: John B. Wyatt IV Signed-off-by: John B. Wyatt IV Signed-off-by: Shuah Khan

pm:cpupower: Add SWIG bindings files for libcpupower

2024-09-06T00:50:07+00:00

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. Added suggestions from Shuah Khan for the README and license discussion. 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 https://swig.org/legal.html and [1] for more details. [1] https://lore.kernel.org/linux-pm/Zqv9BOjxLAgyNP5B@hatbackup/ Suggested-by: Shuah Khan Signed-off-by: John B.
