I'm particularly excited about the "to the perf kernel
infrastructure" :-)

We've got Mathieu Poirier at Linaro working on the drivers for CoreSight
components, with the latest (v5) version here:

http://thread.gmane.org/gmane.linux.ports.arm.kernel/351654

but it was mostly intended to have the processor trace decoded using a
separate tool in userspace. I must say that an idea of getting it all
into perf sounds really interesting.

I've copied Mathieu so he can have a look as well. As for me personally,
I'd like to have 48 hours to digest it all. I've just got back from a
very distant time zone and am suffering a monumental jet lag...
