    From
    Subjectmapping phys mem to kernel virt addr?
    Date
    Hello.

    if i have a pci card, does the OS map and assign base addr correctly that
    the driver
    can then read from the pci_dev structures returned by the pci_find_device()?

    if my card has 2 base addr would the os properly map both to physical addr
    that we can use
    later to map?

    also once you get this addr, how would one map this to kernel virtual addr?
    to we can use
    ptr accesses to read from the board registers.

    Cheers,
    ashokr
