[ECOS] PCI device driver questions
Fri Jan 30 22:21:00 GMT 2004
I'm working on the driver for a PCI device.
There is a region of Bus Address space reserved for mapping PCI I/O and
PCI memory regions.
Where in the PCI driver does one map a processor physical address to a PCI
32/64 bit address.
For example: If I have one device on PCI that has 1 4MB memory BAR, how
would one map that 4MB region into local processor space.
Pointers to some code examples would be great!
