Hi Mathieu,<div><br></div><div>Thanks for the help. Here is my list of details:</div><div><br></div><div>- Clocks: the spec doesn't explain properly that timestamps are an offset from the base time of the clock they refer to. Since I was using 64bit timestamps I somehow assumed that I was using absolute timestamps from the epoch (although the spec doesn't says it either).</div>
<div><br></div><div>- I saw that the lttng-generated traces for metadata are always a multiple of 4k in size (at least the ones I generate for either kernel or user space). I can't find where in the spec it mentions requirements regarding metadata packet padding. I was generating metadata packets that ended up right after my TSDL and eclipse wasn't happy about it (although I didn't try babeltrace). Also I found that the lttng-generated traces have a "empty" metadata packet after the metadata containing the TSDL, I didn't find either any documentation regarding this.</div>

</div></div>Hi Diego,<br>
<br>
Yes, this mailing list would be the proper place, along maybe with<br>
adding the MCA tiwg mailing list in CC, which I'm doing here.<br>
<br>
Thanks,<br>
<br>
Mathieu<br>
