Or if cpu-set is the string "package", then the system summary plus the first CPU in each package is printed. Otherwise, the system summary plus the specified set of CPUs are printed. The cpu-set is ordered from low to high, comma delimited with ".." and "-" permitted to denote a range. eg. 1,2,8,14..17,21-44 .PP \fB--hide column\fP do not show the specified columns.

This is used for making sense of the Digital Thermal Sensor outputs, as they return degrees Celsius below the TCC activation temperature. diff --git a/tools/power/x86/turbostat/turbostat.c b/tools/power/x86/turbostat/turbostat.c index 851eaf06f358..c005d9052679 100644 --- a/tools/power/x86/turbostat/turbostat.c +++ b/tools/power/x86/turbostat/turbostat.c @@ -4153,7 +4153,8 @@ void help() "to print statistics, until interrupted.\n" "--add add a counter\n" " eg. --add msr0x10,u64,cpu,delta,MY_TSC\n" - "--cpu cpu-set limit output to summary plus cpu-set cpu-set\n" + "--cpu cpu-set limit output to summary plus cpu-set:\n" + " {core | package | j,k,l..m,n-p }\n" "--quiet skip decoding system configuration header\n" "--interval sec Override default 5-second measurement interval\n" "--help print this help message\n" @@ -4756,6 +4757,21 @@ void parse_cpu_command(char *optarg) unsigned int start, end; char *next; + if (!strcmp(optarg, "core")) { + if (cpu_subset) + goto error; + show_core_only++; + return; + } + if (!strcmp(optarg, "package")) { + if (cpu_subset) + goto error; + show_pkg_only++; + return; + } + if (show_core_only || show_pkg_only) + goto error; + cpu_subset = CPU_ALLOC(CPU_SUBSET_MAXCPUS); if (cpu_subset == NULL) err(3, "CPU_ALLOC"); @@ -4813,7 +4829,8 @@ void parse_cpu_command(char *optarg) return; error: - fprintf(stderr, "'--cpu %s' malformed\n", optarg); + fprintf(stderr, "\"--cpu %s\" malformed\n", optarg); + help(); exit(-1); } @@ -4867,8 +4884,6 @@ void cmdline(int argc, char **argv) {"Joules", no_argument, 0, 'J'}, {"list", no_argument, 0, 'l'}, {"out", required_argument, 0, 'o'}, - {"Package", no_argument, 0, 'p'}, - {"processor", no_argument, 0, 'p'}, {"quiet", no_argument, 0, 'q'}, {"show", required_argument, 0, 's'}, {"Summary", no_argument, 0, 'S'}, @@ -4879,7 +4894,7 @@ void cmdline(int argc, char **argv) progname = argv[0]; - while ((opt = getopt_long_only(argc, argv, "+C:c:Ddhi:JM:m:o:PpqST:v", + while ((opt = getopt_long_only(argc, argv, "+C:c:Ddhi:JM:m:o:qST:v", long_options, &option_index)) != -1) { switch (opt) { case 'a': @@ -4925,12 +4940,6 @@ void cmdline(int argc, char **argv) case 'o': outf = fopen_or_die(optarg, "w"); break; - case 'P': - show_pkg_only++; - break; - case 'p': - show_core_only++; - break; case 'q': quiet = 1; break; |
