I have two questions: (1) why is this happening? (2) is it possible to make
it work?
Please reply to my address directly, since I'm not on the mailing list.

Fortunately, 'count' is controlled by the driver architecture (AL
RAM, not IO memory. Unfortunately, on this sound card (RME Audio Digi96), I
have to access the on-board buffers directly, using the CPU. Thus, to be
portable, I cannot use mmap directly on the ioremap'd memory, right?

Please read the FAQ at http://www.tux.org/lkml/
the correct one? The copy functions is
directly initiated by the user, and not through an interrupt, so I think the
user space mapping will always be to the correct process. Is that correct?
Since I'm not on the list, I'd like to have answers CC'd to my address. Thank
