Hi again,

I tested this on an ARM board, and results look OK on both babeltrace 
and within TMF. So there must be something wrong with the way timestamps 
are calculated (and/or stored) by LLTng 2.x on the target.

I looked at the timestamps again (having babeltrace dump the 
timestamp-cycles in HEX, sided by timestamp-seconds), and got the following:

Since the most significant 32 bits of the timestamp span from 0xe38 to 
0xe42, whose difference is exactly 0xa (10 in decimal), I would assume 
they are somehow representing the uptime in seconds, whereas the least 
significant 32 bits are (maybe?) really (clock?) cycles.
It looks like the maximum value reached by the least significant 32 bits 
is somewehere near 0x1fff'ffff (so 29 bits as opposed to 32).
It's also easy to spot that the huge (4.3 seconds) gaps occur whenever 
there's an increase in the uppermost 32-bit fraction (0xe38->0xe39, etc...).

Anyway, there's definitely something wrong with the way LLTng actually 
picks up those timestamps.
Could someone please spend a few words on how these timestamps are 
computed on PowerPC?

Thanks a lot!
