While on ARM (little endian) everything seems to work fine, on PowerPC (big endian) I get absolutely meaningless timestamps, ranging to years 2050, 2145, and so on... I get huge gaps (as I see only the time of day part, it looks like hours, but it might be as well be years!) between consecutive events. Groups of adjacent events do sometimes get displayed with reasonably close timestamps though (I guess for those events which got dumped with a compact representation of the timestamp and/or header). The output of babeltrace for the same trace looks OK. Any other fields (pids, tids, task names, etc..) which would be affected by a global endianness problem still look OK, so it's definitely something related to timestamps. Any ideas? Shall I send the affected trace?I cannot say yes enough to having big endian traces for testing. To be honest, we only had x86 traces to test on so far.
That's what I figured... :-)
Thanks for providing this info.
Please find attached the affected testcase.It is a 10-second kernel trace on a PowerPC idle system running a 3.0.40 kernel. The output from babeltrace looks OK.
Thanks! GerlandoP.S. If you could provide some pointers on how to patch/upgrade the tools (to me this whole Eclipse world looks as complicated as a galaxy!), I would really appreciate it! :-)
