When perf report synthesize events from ARM SPE data, it refers to current cpu, pid and tid in the machine. But there's no place to set them in the ARM SPE decoder. I'm seeing all pid/tid is set to -1 and user symbols are not resolved in the output. # perf record -a -e arm_spe_0/ts_enable=1/ sleep 1 # perf report -q | head 8.77% 8.77% :-1 [kernel.kallsyms] [k] format_decode 7.02% 7.02% :-1 [kernel.kallsyms] [k] seq_printf 7.02% 7.02% :-1 [unknown] [.] 0x0000ffff9f687c34 5.26% 5.26% :-1 [kernel.kallsyms] [k] vsnprintf 3.51% 3.51% :-1 [kernel.kallsyms] [k] string 3.51% 3.51% :-1 [unknown] [.] 0x0000ffff9f66ae20 3.51% 3.51% :-1 [unknown] [.] 0x0000ffff9f670b3c 3.51% 3.51% :-1 [unknown] [.] 0x0000ffff9f67c040 1.75% 1.75% :-1 [kernel.kallsyms] [k] ___cache_free 1.75% 1.75% :-1 [kernel.kallsyms] [k] __count_memcg_events Like Intel PT, add context switch records to track task info.

The head pointer of the AUX buffer managed by the arm_spe_pmu.c driver is not monotonically increasing, therefore the find_snapshot callback is needed in order to find the trace data within the AUX buffer and avoid wasting space in the perf.data file. The pointer is assumed to have wrapped if the buffer contains non-zero data at the end. If it has wrapped, the entire contents of the AUX buffer are stored in the perf.data file. Otherwise only the data up to the head pointer is stored. Reviewed-by:

Events like uncore_imc/cas_count_read/ on Skylake open multiple events and then aggregate in the metric leader. To determine the average value per event the number of these events is needed. Add a source_count function that returns this value by counting the number of events with the given metric leader. For most events the value is 1 but for uncore_imc/cas_count_read/ it can yield values like 6. Add a generic test, but manually tested with a test metric that uses the function. Signed-off-by:
