This leads to the energy-pkg event scope to be modified to CCD instead of package. Replacing these macros with their package counterparts fixes the energy-pkg event for AMD CPUs. However due to the difference between the scope of energy-pkg event for Intel and AMD CPUs, we have to replace these macros conditionally only for AMD CPUs. On a 12 CCD 1 Package AMD Zen4 Genoa machine: Before: $ cat /sys/devices/power/cpumask 0,8,16,24,32,40,48,56,64,72,80,88. The expected cpumask here is supposed to be just "0", as it is a package scope event, only one CPU will be collecting the event for all the CPUs in the package. After: $ cat /sys/devices/power/cpumask 0 Signed-off-by: Dhananjay Ugwekar Fixes: 63edbaa48a57 ("x86/cpu/topology: Add support for the AMD 0x80000026 leaf") --- arch/x86/events/rapl.c | 30 ++++++++++++++++++++++++++---- 1 file changed, 26 insertions(+), 4 deletions(-) diff --git a/arch/x86/events/rapl.c b/arch/x86/events/rapl.c index b985ca79cf97..73be25e1f4b4 100644 --- a/arch/x86/events/rapl.c +++ b/arch/x86/events/rapl.c @@ -103,6 +103,10 @@ static struct perf_pmu_events_attr event_attr_##v = { \ .event_str = str, \ }; +#define rapl_pmu_is_pkg_scope() \ + (boot_cpu_data.x86_vendor == X86_VENDOR_AMD || \ + boot_cpu_data.x86_vendor == X86_VENDOR_HYGON) + struct rapl_pmu { raw_spinlock_t lock; int n_active; @@ -140,9 +144,21 @@ static unsigned int rapl_cntr_mask; static u64 rapl_timer_ms; static struct perf_msr *rapl_msrs; +static inline unsigned int get_rapl_pmu_idx(int cpu) +{ + return rapl_pmu_is_pkg_scope() ? topology_logical_package_id(cpu) : + topology_logical_die_id(cpu); +} + +static inline const struct cpumask *get_rapl_pmu_cpumask(int cpu) +{ + return rapl_pmu_is_pkg_scope() ? topology_core_cpumask(cpu) : + topology_die_cpumask(cpu); +} + static inline struct rapl_pmu *cpu_to_rapl_pmu(unsigned int cpu) { - unsigned int rapl_pmu_idx = topology_logical_die_id(cpu); + unsigned int rapl_pmu_idx = get_rapl_pmu_idx(cpu); /* * The unsigned check also catches the '-1' return value for non @@ -543,6 +559,7 @@ static struct perf_msr amd_rapl_msrs[] = { static int rapl_cpu_offline(unsigned int cpu) { + const struct cpumask *rapl_pmu_cpumask = get_rapl_pmu_cpumask(cpu); struct rapl_pmu *pmu = cpu_to_rapl_pmu(cpu); int target; @@ -552,7 +569,7 @@ static int rapl_cpu_offline(unsigned int cpu) pmu->cpu = -1; /* Find a new cpu to collect rapl events */ - target = cpumask_any_but(topology_die_cpumask(cpu), cpu); + target = cpumask_any_but(rapl_pmu_cpumask, cpu); /* Migrate rapl events to the new target */ if (target < nr_cpu_ids) { @@ -565,6 +582,8 @@ static int rapl_cpu_offline(unsigned int cpu) static int rapl_cpu_online(unsigned int cpu) { + unsigned int rapl_pmu_idx = get_rapl_pmu_idx(cpu); + const struct cpumask *rapl_pmu_cpumask = get_rapl_pmu_cpumask(cpu); struct rapl_pmu *pmu = cpu_to_rapl_pmu(cpu); int target; @@ -579,14 +598,14 @@ static int rapl_cpu_online(unsigned int cpu) pmu->timer_interval = ms_to_ktime(rapl_timer_ms); rapl_hrtimer_init(pmu); - rapl_pmus->pmus[topology_logical_die_id(cpu)] = pmu; + rapl_pmus->pmus[rapl_pmu_idx] = pmu; } /* * Check if there is an online cpu in the package which collects rapl * events already. */ - target = cpumask_any_and(&rapl_cpu_mask, topology_die_cpumask(cpu)); + target = cpumask_any_and(&rapl_cpu_mask, rapl_pmu_cpumask); if (target < nr_cpu_ids) return 0; @@ -677,6 +696,9 @@ static int __init init_rapl_pmus(void) { int nr_rapl_pmu = topology_max_packages() * topology_max_dies_per_package(); + if (rapl_pmu_is_pkg_scope()) + nr_rapl_pmu = topology_max_packages(); + rapl_pmus = kzalloc(struct_size(rapl_pmus, pmus, nr_rapl_pmu), GFP_KERNEL); if (!rapl_pmus) return -ENOMEM;
