Hi,
I am using lttng-modules 2.12.5 with a 5.4.93 kernel on an aarch64
target. After creating a session I run
*lttng enable-event -k block**
to enable all the block_ kernel events but when I run babeltrace on the
generated traces I get a handful of
*[warning] Unknown value 33 in enum.
...
before that change in the kernel tracer
Babeltrace would have simply printed "rwbs = 33" so you're not losing
any information here.
So, try it out with Babeltrace2, it should work as you expect.
Cheers,
Francis
