From ef0e60083f768b32cda17b1b0ca9519405db89a6 Mon Sep 17 00:00:00 2001 From: Len Brown Date: Tue, 17 Feb 2026 20:31:51 -0600 Subject: [PATCH] tools/power turbostat: Fix AMD RAPL regression turbostat.c:8688: rapl_perf_init: Assertion `next_domain < num_domains' failed. Two recent cleanup patches that were not supposed to change anything broke the core_id code needed for AMD RAPL initialization: commit 070e92361eec ("tools/power turbostat: Enhance HT enumeration") commit ddf60e38ca04 ("tools/power turbostat: Simplify global core_id calculation") Reported-by: Linus Torvalds Signed-off-by: Len Brown --- tools/power/x86/turbostat/turbostat.c | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) diff --git a/tools/power/x86/turbostat/turbostat.c b/tools/power/x86/turbostat/turbostat.c index 1aace9b3269e..1a2671c28209 100644 --- a/tools/power/x86/turbostat/turbostat.c +++ b/tools/power/x86/turbostat/turbostat.c @@ -5164,7 +5164,7 @@ static inline int get_rapl_domain_id(int cpu) if (!platform->has_per_core_rapl) return cpus[cpu].package_id; - return GLOBAL_CORE_ID(cpu, cpus[cpu].package_id); + return GLOBAL_CORE_ID(cpus[cpu].core_id, cpus[cpu].package_id); } /* @@ -9633,7 +9633,6 @@ void topology_probe(bool startup) } topo.max_core_id = max_core_id; /* within a package */ topo.max_package_id = max_package_id; - topo.num_cores = (max_core_id + 1) * topo.num_packages; /* per system */ topo.cores_per_node = max_core_id + 1; if (debug > 1)
