question about ioport_map function

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello all

From what I understand, to map io ports to virtual memory, we should use request_region, ioport_map/unmap and ioread/write functions.

These are for architectures having input, output machine instructions like x86, x86_64.

And the return address of ioport_map is physical address.

Is my understanding correct?

Thanks!

Chan Kim
