PCI_MMAP_LEGACY_IO(9)						Hardware Interfaces					     PCI_MMAP_LEGACY_IO(9)

NAME

       pci_mmap_legacy_io - map legacy PCI IO into user memory space

SYNOPSIS

       int pci_mmap_legacy_io(struct file * filp, struct kobject * kobj, struct bin_attribute * attr, struct vm_area_struct * vma);

ARGUMENTS

       filp
	   open sysfs file

       kobj
	   kobject corresponding to device to be mapped

       attr
	   struct bin_attribute for this file

       vma
	   struct vm_area_struct passed to mmap

DESCRIPTION

       Uses an arch specific callback, pci_mmap_legacy_io_page_range, to mmap legacy IO space (first meg of bus space) into application virtual
       memory space. Returns -ENOSYS if the operation isn't supported
