From 44460efe44e05eae2f21e57d06d542bbbb792e65 Mon Sep 17 00:00:00 2001 From: Youquan Song Date: Sat, 14 Sep 2019 12:45:43 -0700 Subject: tools/power/x86/intel-speed-select: Fix high priority core mask over count If the CPU package has the less logical CPU than topo_max_cpus, but un-present CPU's punit_cpu_core will be initiated to 0 and they will be count to core 0 Like below, there are only 10 high priority cores (20 logical CPUs) in the CPU package, but it count to 27 logic CPUs. ./intel-speed-select base-freq info -l 0 | grep mask high-priority-cpu-mask:7f000179,f000179f With the fix patch: ./intel-speed-select base-freq info -l 0 high-priority-cpu-mask:00000179,f000179f Signed-off-by: Youquan Song Signed-off-by: Srinivas Pandruvada Signed-off-by: Andy Shevchenko --- tools/power/x86/intel-speed-select/isst-config.c | 3 +++ 1 file changed, 3 insertions(+) (limited to 'tools/power') diff --git a/tools/power/x86/intel-speed-select/isst-config.c b/tools/power/x86/intel-speed-select/isst-config.c index 59753b3917bb..83ac72902b36 100644 --- a/tools/power/x86/intel-speed-select/isst-config.c +++ b/tools/power/x86/intel-speed-select/isst-config.c @@ -402,6 +402,9 @@ void set_cpu_mask_from_punit_coremask(int cpu, unsigned long long core_mask, int j; for (j = 0; j < topo_max_cpus; ++j) { + if (!CPU_ISSET_S(j, present_cpumask_size, present_cpumask)) + continue; + if (cpu_map[j].pkg_id == pkg_id && cpu_map[j].die_id == die_id && cpu_map[j].punit_cpu_core == i) { -- cgit
