I posted a story last night about how I was able to achieve Tri-core SMP under Trinux. Unfortunately, I was incorrect. While I did however manage to increase performance in Trinux quite a bit, I was mistaken about it running on all three cores of the Espresso processor. Its sadly still running on one core. We have much more work to do to reach true SMP support under Trinux.
Sorry for the mass confusion :(. More info can be found here: http://gbatemp.net/threads/vwii-tri-core-linux.351024/page-32#post-5187457
