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.
