Looking at the arm code, I noticed that we have the PMC stuff from NetBSD, but we don't use it. NetBSD has XScale PMC support but we haven't ported it yet. In any case, I plan to port the NetBSD code to our hwpmc, so we can remove NetBSD PMC defines. See http://people.freebsd.org/~rpaulo/xscalepmc.diff for what I'm trying to accomplish. -- Rui Paulo
