tools/power/cpupower: Fix initializer override in hsw_ext_cstates

2020-02-11T20:03:13+00:00

commit 7e5705c635ecfccde559ebbbe1eaf05b5cc60529 upstream. When building cpupower with clang, the following warning appears: utils/idle_monitor/hsw_ext_idle.c:42:16: warning: initializer overrides prior initialization of this subobject [-Winitializer-overrides] .desc = N_("Processor Package C2"), ^~~~~~~~~~~~~~~~~~~~~~ ./utils/helpers/helpers.h:25:33: note: expanded from macro 'N_' #define N_(String) gettext_noop(String) ^~~~~~ ./utils/helpers/helpers.h:23:30: note: expanded from macro 'gettext_noop' #define gettext_noop(String) String ^~~~~~ utils/idle_monitor/hsw_ext_idle.c:41:16: note: previous initialization is here .desc = N_("Processor Package C9"), ^~~~~~~~~~~~~~~~~~~~~~ ./utils/helpers/helpers.h:25:33: note: expanded from macro 'N_' #define N_(String) gettext_noop(String) ^~~~~~ ./utils/helpers/helpers.h:23:30: note: expanded from macro 'gettext_noop' #define gettext_noop(String) String ^~~~~~ 1 warning generated. This appears to be a copy and paste or merge mistake because the name and id fields both have PC9 in them, not PC2. Remove the second assignment to fix the warning.

cpupower: remove stringop-truncation waring

2019-02-11T17:53:16+00:00

commit 8a7e2d2ea080d10a189a1d611344b0330468ebc3 upstream. The strncpy doesn't null terminate the string because the size is too short by one byte. parse.c: In function ‘prepare_default_config’: parse.c:148:2: warning: ‘strncpy’ output truncated before terminating nul copying 8 bytes from a string of the same length [-Wstringop-truncation] strncpy(config->governor, "ondemand", 8); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The normal method of passing the length of the destination buffer works correctly here.

cpupower: Fix turbo frequency reporting for pre-Sandy Bridge cores

2017-07-18T17:40:35+00:00

commit 4cca0457686e4ee1677d69469e4ddfd94d389a80 upstream. The switch that conditionally sets CPUPOWER_CAP_HAS_TURBO_RATIO and CPUPOWER_CAP_IS_SNB flags is missing a break, so all cores get both flags set and an assumed base clock of 100 MHz for turbo values.
