Correct. Do the bdbuf tests currently fail on SMP ?
They do not fail since they run in single processor mode.

Agreed and I hope this does not mean the whole file moves to goto's. I
am not fan of goto's.

A resource is something that has at most one owner at a time and may
have multiple rivals in case an owner is present. The owner and rivals
are impersonated via resource nodes. A resource is represented via the
resource control structure. The resource controls and nodes are
organized as trees.

Andre,
If you have not seen this library, please check this out:
http://wiringpi.com
It looks like a good resource programming the Raspberry Pi GPIO. It may
give you some insight and ideas about the GPIO API. The code appears to be
LGPL.

OK, that's good to know. But it could at least help shape the RTEMS GPIO
API.
