9 int pci_mmap_legacy_io(struct file * filp, struct kobject * kobj,
10 struct bin_attribute * attr,
11 struct vm_area_struct * vma);
12
14 filp
15 open sysfs file
16
17 kobj
18 kobject corresponding to device to be mapped
19
20 attr
21 struct bin_attribute for this file
22
23 vma
24 struct vm_area_struct passed to mmap
25
27 Uses an arch specific callback, pci_mmap_legacy_io_page_range, to mmap
28 legacy IO space (first meg of bus space) into application virtual
29 memory space. Returns -ENOSYS if the operation isn't supported
