Hello all,
Question, when doing an ioremap() of a PCI resource which is more correct?
iobase = pci_resource_start(pcidev, bar);
len = pci_resource_len(pcidev, bar);
mmio = ioremap(iobase, len);
or
mmio = pci_ioremap_bar(pcidev, bar);
pci_ioremap_bar() does some extra sanity checking to make sure the bar
is actually a memory resource and then does an ioremap_nocache().
If the ioremap() is in order to talk to the registers on the PCI device wouldn't
the pci_ioremap_bar() be more correct?
Thanks for any replies,
Hartley
