1fb2daa60de640efb13f907d43d72d28763f696c - x86/resctrl: Discover hardware telemetry events

Thu, 08 Jan 2026 18:42:26 +0100

x86/resctrl: Discover hardware telemetry eventsEach CPU collects data for telemetry events that it sends to the nearesttelemetry event aggregator either when the value of MSR_IA32_PQR_ASSOC.RMIDchanges, or when a two millisecond timer expires.There is a feature type ("energy" or "perf"), GUID, and MMIO region associatedwith each aggregator. This combination links to an XML description of theset of telemetry events tracked by the aggregator. XML files are publishedby Intel in a GitHub repository¹.The telemetry event aggregators maintain per-RMID per-event counts of thetotal seen for all the CPUs. There may be multiple telemetry event aggregatorsper package.There are separate sets of aggregators for each feature type. Aggregatorsin a set may have different GUIDs. All aggregators with the same featuretype and GUID are symmetric keeping counts for the same set of events forthe CPUs that provide data to them.The XML file for each aggregator provides the following information:0) Feature type of the events ("perf" or "energy")1) Which telemetry events are tracked by the aggregator.2) The order in which the event counters appear for each RMID.3) The value type of each event counter (integer or fixed-point).4) The number of RMIDs supported.5) Which additional aggregator status registers are included.6) The total size of the MMIO region for an aggregator.Introduce struct event_group that condenses the relevant information froman XML file. Hereafter an "event group" refers to a group of events of aparticular feature type (event_group::pfname set to "energy" or "perf") witha particular GUID.Use event_group::pfname to determine the feature id needed to obtain theaggregator details. It will later be used in console messages and with therdt= boot parameter.The INTEL_PMT_TELEMETRY driver enumerates support for telemetry events.This driver provides intel_pmt_get_regions_by_feature() to list all availabletelemetry event aggregators of a given feature type. The list includes the"guid", the base address in MMIO space for the region where the event countersare exposed, and the package id where the all the CPUs that report to thisaggregator are located.Call INTEL_PMT_TELEMETRY's intel_pmt_get_regions_by_feature() for each eventgroup to obtain a private copy of that event group's aggregator data. Duplicatethe aggregator data between event groups that have the same feature typebut different GUID. Further processing on this private copy will be uniqueto the event group. ¹https://github.com/intel/Intel-PMT [ bp: Zap text explaining the code, s/guid/GUID/g ]Signed-off-by: Tony Luck Signed-off-by: Borislav Petkov (AMD) Reviewed-by: Reinette Chatre Link: https://lore.kernel.org/20251217172121.12030-1-tony.luck@intel.com List of files: /linux/arch/x86/kernel/cpu/resctrl/Makefile
