I haven't followed this work closely, but I have a question: The first poulsbos used to crash badly when attempting to map the GTT write-combined, and IIRC it didn't even advertise write-combining capabilities on the PCI BAR. Has this been improved on lately or how is this handled currently? Thanks, Thomas
