perf vendor events arm64: Fix incorrect Hisi hip08 L3 metrics

2022-10-26T14:01:56Z

Commit 0cc177cfc95d565e ("perf vendor events arm64: Add Hisi hip08 L3 metrics") add L3 metrics of hip08, but some metrics (IF_BP_MISP_BR_RET, IF_BP_MISP_BR_RET, IF_BP_MISP_BR_BL) have incorrect event number due to the mistakes in document, which caused incorrect result. Fix the incorrect metrics.

perf list: Fix PMU name pai_crypto in perf list on s390

2022-10-25T20:40:48Z

Commit e0b23af82d6f454c ("perf list: Add PMU pai_crypto event description for IBM z16") introduced the "Processor Activity Instrumentation" for cryptographic counters for z16. The PMU device driver exports the counters via sysfs files listed in directory /sys/devices/pai_crypto. To specify an event from that PMU, use 'perf stat -e pai_crypto/XXX/'. However the JSON file mentioned in above commit exports the counter decriptions in file pmu-events/arch/s390/cf_z16/pai.json. Rename this file to pmu-events/arch/s390/cf_z16/pai_crypto.json to make the naming consistent. Now 'perf list' shows the counter names under pai_crypto section: pai_crypto: CRYPTO_ALL [CRYPTO ALL. Unit: pai_crypto] ... Output before was pai: CRYPTO_ALL [CRYPTO ALL. Unit: pai_crypto] ...

perf vendor events power10: Fix hv-24x7 metric events

2022-10-25T20:40:48Z

Testcase stat_all_metrics.sh fails in powerpc: 90: perf all metrics test : FAILED! The testcase "stat_all_metrics.sh" verifies perf stat result for all the metric events present in perf list. It runs perf metric events with various commands and expects non-empty metric result. Incase of powerpc:hv-24x7 events, some of the event count can be 0 based on system configuration. And if that event used as denominator in divide equation, it can cause divide by 0 error. The current nest_metric.json file creating divide by 0 issue for some of the metric events, which results in failure of the "stat_all_metrics.sh" test case. Most of the metrics events have cycles or an event which expect to have a larger value as denominator, so adding 1 to the denominator of the metric expression as a fix. Result in powerpc box after this patch changes: 90: perf all metrics test : Ok Fixes: a3cbcadfdfc330c2 ("perf vendor events power10: Adds 24x7 nest metric events for power10 platform") Signed-off-by: Kajol Jain Reviewed-by: Madhavan Srinivasan Cc: Athira Jajeev Cc: Disha Goel Cc: Jiri Olsa Cc: Kajol Jain Cc: linuxppc-dev@lists.ozlabs.org Cc: Michael Ellerman Cc: Nageswara R Sastry Link: https://lore.kernel.org/r/20221014140220.122251-1-kjain@linux.ibm.com Signed-off-by: Arnaldo Carvalho de Melo

perf vendor events: Update Intel broadwellde

Events remain at v23, and the metrics are based on TMA 4.4 full. Use script at: https://github.com/intel/event-converter-for-linux-perf/blob/master/download_and_gen.py with updates at: https://github.com/captain5050/event-converter-for-linux-perf Updates include: - Switch for core metrics from BDX to BDW. - Switch for Page_Walks_Utilization to BDX version. - Rename of topdown TMA metrics from Frontend_Bound to tma_frontend_bound. - Addition of all 6 levels of TMA metrics. Child metrics are placed in a group named after their parent allowing children of a metric to be easily measured using the metric name with a _group suffix. - ## and ##? operators are correctly expanded. - The locate-with column is added to the long description describing a sampling event. - Metrics are written in terms of other metrics to reduce the expression size and increase readability.
