Hello,
I am writing a pci
device driver in linux to talk to a modem module. My driver code has
detected the modem module using
pci_find_device()
startAddr =
pci_resource_start(pciDev,i);
flags = pci_resource_flags(pciDev,i);
flags = pci_resource_flags(pciDev,i);
Now that I have the
starting physical address of the pci device, do I have to use ioremap() on this
physical address in order to talk to the device (in kernel space) ? Can I
talk the device using the detected physical address
directly?
Thank
you
Thanh
