[PATCH 2/2] tools/power turbostat: bugfix: fix several invalid parameters

From: Chen Yu
Date: Sun Dec 13 2015 - 08:05:05 EST


dump_cstate_pstate_config_info is invoked with no parameters,
which might cause this function to misjudge the processor family
and model. Fix this by passing family and model to it.

Besides, fix the compiling warning caused by missing type declaration
in dump_cstate_pstate_config_info, get_tdp and perf_limit_reasons_probe:

turbostat.c: In function âdump_cstate_pstate_config_infoâ:
turbostat.c:1973:1: warning: type of âfamilyâ defaults to âintâ [-Wimplicit-int]
dump_cstate_pstate_config_info(family, model)
^
turbostat.c:1973:1: warning: type of âmodelâ defaults to âintâ [-Wimplicit-int]
turbostat.c: In function âget_tdpâ:
turbostat.c:2145:8: warning: type of âmodelâ defaults to âintâ [-Wimplicit-int]
double get_tdp(model)
^
turbostat.c: In function âperf_limit_reasons_probeâ:
turbostat.c:2259:6: warning: type of âfamilyâ defaults to âintâ [-Wimplicit-int]
void perf_limit_reasons_probe(family, model)
^
turbostat.c:2259:6: warning: type of âmodelâ defaults to âintâ [-Wimplicit-int]
