pm: cpupower: bench: Prevent NULL dereference on malloc failure

2025-02-19T20:48:08+00:00

If malloc returns NULL due to low memory, 'config' pointer can be NULL. Add a check to prevent NULL dereference. Link: https://lore.kernel.org/r/20250219122715.3892223-1-quic_zhonhan@quicinc.com Signed-off-by: Zhongqiu Han Signed-off-by: Shuah Khan

pm: cpupower: bench: print config file path when open cpufreq-bench.conf fails

2024-09-30T15:40:30+00:00

Print out the config file path when fopen failed. It will be easy for users to know where to create the file. Since we are here, use strerror to drop the usage of perror. Signed-off-by: Peng Fan Signed-off-by: Shuah Khan

cpupower: Disable direct build of the 'bench' subproject

2024-06-28T21:55:20+00:00

Execution of the 'make' command in the 'bench' subfolder causes the following error: $ make O=cpupower/build/ DESTDIR=cpupower/install/ -j8 " CC " cpupower/build//main.o " CC " cpupower/build//parse.o /bin/sh: 1: " CC "cpupower/build//system.o CC : not found make: *** [Makefile:21: cpupower/build//main.o] Error 127 make: *** Waiting for unfinished jobs.... /bin/sh: 1: CC : not found /bin/sh: 1: CC : not found 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.
