[tracecompass-dev] CTF trace reader: ordering events in multiple streams

[Phyo Kyaw <phyokyaw.uk@xxxxxxxxx>]

Dear all,

We have generated CTF trace file with multiple streams for each core and in some cases CTF events can have same timestamp during to sampling rate faster than clock speed. In this case the order seems to be what ever created first and assigned reader.

Generated

Event in stream file 1:    001 Core 0 Started work

Event in stream file 2:    001 Core 1 Completed work

Read back

001 Core 1 Completed work

001 Core 0 Started work

Looks like CTFTraceReader() has StreamInputReaderTimestampComparator() which is a bit inflexible to extend or modify.

Any suggestions to make it shown as written. I understand no other information to order them but we can add extra attribute during creation to set the order.

Thanks

Phyo
