# pci\_create\_legacy\_files(9)

create legacy I/O port and memory files

## NAME

pci\_create\_legacy\_files - create legacy I/O port and memory files

## SYNOPSIS

**void pci\_create\_legacy\_files(struct pci\_bus \*** *b***);**

## ARGUMENTS

*b*

bus to create files under

## DESCRIPTION

Some platforms allow access to legacy I/O port and ISA memory space on a per-bus basis. This routine creates the files and ties them into their associated read, write and mmap files from pci-sysfs.c

On error unwind, but don't propagate the error to the caller as it is ok to set up the PCI bus without these files.
