[lttng-dev] [PATCH lttng-tools] Test add-context perf raw command

[Mathieu Desnoyers]

What happens if we run this test on other architecture
than x86 ?

We should try to test this feature throughout the stack,
including tracing and looking at the result, but somehow
check that we are on the right architecture to do so.

Thanks,

Mathieu
