Hi all,
I'm currently running kvm-88 with a parallel port forwarding and Win XP as
guest. The Windows XP guest talks directly to the hardware registers of the
parallel port and tries to programm a piece of hardware over a proprietary
softwar tool. The hardware is connected via Parallel port and a JTAG
interface. (The Chip ID is recognized correctly over the port)
Running the Windows natively on the system programming is successful. If I
run it within the windows guest the Busy flag of the parallel port seems to
be "too slow". That means the software expects a low signal but the bit is
still set.
Are there any posibilities to enable a more direct access to the parallel
port? Am I able to map "somehow" the heap of I/O registers directly into
the guest for accessing it? What does the "linux host driver layer" do with
the parallel port bits? Are they somehow modified within the driver?
Thanks!
Best regards,
Erik
