2024-09-23pm: cpupower: Clean up bindings gitignoreJohn B. Wyatt IV1-2/+1
Add SPDX identifier to the gitignore. Remove the comment and .i file since the file it references was removed in another patch. This patch depends on Min-Hua Chen's 'pm: cpupower: rename raw_pylibcpupower.i'. Signed-off-by: John B. Wyatt IV <[email protected]> Signed-off-by: John B.

2024-09-13pm: cpupower: rename raw_pylibcpupower.iMin-Hua Chen2-2/+2
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.

2024-09-06pm:cpupower: Add error warning when SWIG is not installedJohn B. Wyatt IV1-9/+11
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.

2024-09-05pm:cpupower: Include test_raw_pylibcpupower.pyJohn B. Wyatt IV1-0/+42
This script demonstrates how to make use of, and tests, the bindings. In the future, this script could become part of a larger test suite to test the bindings and libcpupower. Signed-off-by: John B.

2024-09-05pm:cpupower: Add SWIG bindings files for libcpupowerJohn B. Wyatt IV4-0/+345
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 <[email protected]> Signed-off-by: John B.
