Hi all,
in order both to profile the performance of my rt threads, and to
perform timed operations (such as sem_timedwait), I'm using the
clock_gettime() function.
Using as a parameter CLOCK_REALTIME everything appears to work as
expected, but if I attempt to use CLOCK_MONOTONIC (which should be a
more reliable timing source, from what I read), I get bogus times.
This occurs on different platforms, and with different kernel
versions/rt patch. (3.10.10-rt7 - 3.10.67-rt71 - 3.12.31-rt45).
Am I missing something obvious, such as a kernel misconfiguration, or
this is something to be expected?
Any hint will be appreciated.
Thanks in advance,
Giuliano
