| |
Hi,
I have the following PCI device which has it's registers mapped to PCI memory space. How do I access the device in a driver? Accessing a pointer obtained using phys_to_virt(0xffae0000) causes a protection fault.
Bus 0, device 16, function 0: Multimedia controller: Unknown vendor Unknown device (rev 1). Vendor id=1057. Device id=1801. Medium devsel. Fast back-to-back capable. Master Capable. Latency=32. Non-prefetchable 32 bit memory at 0xffae0000.
Best regards,
