[lttng-dev] Problem with perf:thread in 2.5.0

[Evgeniy Ivanov]

Hi!

I use lttng-2.5.0 (tools, modules, …) and linux-3.8.13. When I try to add
context for performance counters I get the following error:

> lttng add-context -u -t perf:cpu:cpu-cycles
Error: perf:cpu:cpu-cycles: UST invalid context
Warning: Some command(s) went wrong

We have another machine with 2.5.0 (modules are not installed though) and
adding perf:cpu:cpu-cycles works fine, but it is always zero in results.

Evgeniy
