2026-08-18perf vendor events arm64: Fix Tegra410 Olympus event 0x0197Besar Wicaksono
The name and description for NVIDIA Tegra410 Olympus implementation-defined event 0x0197 incorrectly indicate a TXREQ limit between one quarter and one half. Correct them to describe a TXREQ limit below one half.

2026-08-18perf vendor events arm64: fix swapped MetricGroup for Tegra410 L1 prefetcher ↵Saurav Sachidanand
metrics The L1D prefetcher metrics (l1d_cache_rw_miss_ratio, l1d_demand_accesses, etc.) were incorrectly assigned to MetricGroup "L1I_Prefetcher_Effectiveness" and vice versa. This causes 'perf stat --metric-group L1D_Prefetcher_Effectiveness' to display L1I metrics, which is misleading. Swap the MetricGroup assignments so L1D metrics are in the L1D group and L1I metrics are in the L1I group.

2026-08-04perf vendor events intel: Fix Novalake CPUID regex in mapfile.csvChun-Tse Shao
Based on offline discussion with Intel in lore.kernel.org/20260715211144.3144895-1-ctshao@google.com, we decided to drop the leading zero from Nova Lake models 0x01 and 0x03 in mapfile.csv to match single-digit model numbers without zero padding (GenuineIntel-18-[13]).

2026-08-03perf pmu-events: Fix typo in idle-cycles-frontend descriptionPu Hu
The brief description of the idle-cycles-frontend legacy hardware event refers to its alias as "stalled-cycles-fronted", but there is no such event. The correct event name is "stalled-cycles-frontend". This typo is visible in the output of "perf list", for example: idle-cycles-frontend [Stalled cycles during issue [This event is an alias of stalled-cycles-fronted]. Unit: armv8_pmuv3] Fix the spelling so that the description points to the valid event name. Signed-off-by: Pu Hu <hupu@transsion.com> Signed-off-by: Namhyung Kim <namhyung@kernel.org>

2026-04-02perf metrics: Make common stalled metrics conditional on having the eventIan Rogers
The metric code uses the event parsing code but it generally assumes all events are supported. Arnaldo reported AMD supporting stalled-cycles-frontend but not stalled-cycles-backend [1]. An issue with this is that before parsing happens the metric code tries to share events within groups to reduce the number of events and multiplexing. If the group has some supported and not supported events, the whole group will become broken. To avoid this situation add has_event tests to the metrics for stalled-cycles-frontend and stalled-cycles-backend. has_events is evaluated when parsing the metric and its result constant propagated (with if-elses) to reduce the number of events. This means when the metric code considers sharing the events, only supported events will be shared. Note for backporting. This change updates tools/perf/pmu-events/empty-pmu-events.c a convenience file for builds on systems without python present. While the metrics.json code should backport easily there can be conflicts on empty-pmu-events.c. In this case the build will have left a file test-empty-pmu-events.c that can be copied over empty-pmu-events.c to resolve issues and make an appropriate empty-pmu-events.c for the json in the source tree at the time of the build.
