I have been thinking about doing something slightly more intelligent with tLB miss handling and selecting the next entry to write. At the moment I am doing stuff like setting up PTXdist (which does indeed rule by the way once you get the right configuration) however I could do with something for the holiday period so please keep me updated ~ and I will try to fit bits in when I get time with a board to do it. There is an EPPC405 which I am hoping to borrow for a while because it is not particularly being used but I will see what happens about it. Cheers, Jon. P.S. I am going to be at FOSDEM and welcome the idea of meeting other ppc 405 or Virtex II Pro or indeed anyone from this list. ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
