[driver-discuss] device driver for a memory mapped device

[Sevin Fide]

Hi,

I've got a memory mapped device, but the OS doesn't
let me access it in user space without a driver. So, I
need to write a driver to bind the driver to my device
at location 0x7fff00000000. Attached you will find my
driver code. But when I mmap the driver into user
space, the device at 0x7fff00000000 is not accessed at
all. So, I believe there is a problem in probing and
attaching the device. Could you please take a look at
my code and tell me what I'm doing wrong? I'm new to
device drivers. Thank you.
