perf event: Add 'simd_flags' field to 'struct perf_sample'

2023-03-20T22:27:00+00:00

Add new field to 'struct perf_sample' to store flags related to SIMD ops. It will be used to store SIMD information from SVE and NEON when profiling using ARM SPE.

perf report: Support Retire Latency

2023-02-03T20:24:02+00:00

The Retire Latency field is added in the var3_w of the PERF_SAMPLE_WEIGHT_STRUCT. The Retire Latency reports pipeline stall of this instruction compared to the previous instruction in cycles. That's quite useful to display the information with perf mem report. The p_stage_cyc for Power is also from the var3_w. Union the p_stage_cyc and retire_lat to share the code. Implement X86 specific codes to display the X86 specific header. Add a new sort key retire_lat for the Retire Latency.

perf tools: Move 'struct perf_sample' to a separate header file to disentangle headers

2022-10-31T14:06:41+00:00

Some places were including event.h just to get 'struct perf_sample', move it to a separate place so that we speed up a bit the build. Signed-off-by: Arnaldo Carvalho de Melo
