MmMapIoSpace
This function maps the specified physical address range to nonpaged
process-dependent address space, providing a directly mapped virtual address
to the device.

Internally what exactly happens behing this API call. How does translation
of address occurs??
suppose i have address dedicated for LCD controller or any other peripheral.
In my driver i call MmMapIoSpace to access the device..
How will the processor know this address is meant for that particular device??
Or how does transaltion of address happens?

Any suggestion is appreciated.

Thanks
