    Yes, as fully as it was originally meant to be. Again.
    I don't know of any more urgent bugs.

    It passes the testmmiotrace.ko test, and also notices overruns if they
    happen. Still untested with the nvidia proprietary driver, though, or
    with SMP, but it should work.

    btw. the testmmiotrace.ko testing cannot be automated, since it
    involves writing to "somewhere" in the PCI address space and is
    therefore a bit dangerous.


    Thanks.
