perf report: Create option to disable raw event ordering
Warning "dso not found" is reported when using "perf report -D". 66702781413407 0x32c0 [0x30]: PERF_RECORD_SAMPLE(IP, 0x2): 28177/28177: 0x55e493e00563 period: 106578 addr: 0 ... thread: perf:28177 ...... dso: <not found> 66702727832429 0x9dd8 [0x38]: PERF_RECORD_COMM exec: triad_loop:28177/28177 The PERF_RECORD_SAMPLE event (timestamp: 66702781413407) should be after the PERF_RECORD_COMM event (timestamp: 66702727832429), but it's early processed. So for most of cases, it makes sense to keep the event ordered even for dump mode. But it would be also useful to disable ordered_events for reporting raw dump to see events as they are stored in the perf.data file. So now, set ordered_events by default to true and add a new option 'disable-order' to disable it. For example, perf report -D --disable-order Fixes: 977f739b7126b ("perf report: Disable ordered_events for raw dump") Signed-off-by: Jin Yao <[email protected]> Acked-by: Jiri Olsa <[email protected]> Cc: Alexander Shishkin <[email protected]> Cc: Andi Kleen <[email protected]> Cc: Ingo Molnar <[email protected]> Cc: Jin Yao <[email protected]> Cc: Kan Liang <[email protected]> Cc: Peter Zijlstra <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Arnaldo Carvalho de Melo <[email protected]>
