Hi there,

I was hoping that someone might be be able to help me out using the
uio_pci_generic driver.

To gain access to the memory in the card I try to do an mmap but it
returns an error.

I was wondering if the mapping of the PCI memory regions is automatic?
I am not seeing /sys/class/uio/uio0/maps

Do I have to do something to get these to appear?

I would appreciate any help or pointers that you can give.

Regards,

Billy
