Right... I've just nearly died laughing... ;-)
We could have discussed technical details for a looong time then :-)
Thanks for be

Ah I think there is a misunderstanding here, damn these TLA:s.

Thanks Pawel, now I understand better the Coresight architecture,
but STM has its own hardware architecture independent to Coresight not
connected to Debug Bus nor Funnel Trace bus.
STM exposes a set of registers to our main CPU for its control, it is
connected to our ST-BUS through interconnect.

Well, what I mean is that xTMs - ETM/PTM tracing execution flow, ITM

I'm not an expert here, b
Hi All,
This proposal is a call for contribution for a STM driver
and its possible usages in kernel tracing infrastructure.
I'd like to know if another ARM SoC plan to use or already use STM or
some similar hardware enabling the same kind of MIPI trace points.
If yes, we can share our works.
