    Subjectvideo drivers, agp, mtrr, and write-combining
    I have a silly question.

    I've noticed that some, though no all, video drivers add their video memory
    to MTRR as 'write-combining' if both MTRR and AGP are configured in.

    Is there a reason that all video drivers don't do this? Is it all would
    benefit from write-combining memory, but that some simply haven't been
    updated to take advantage of it? Or could write-combining actually be
    detrimental to some video drivers? (And if the former, would it make
    more sense to do the mtrr_add in a central location, say agpgart?)
