PCI_CREATE_LEGACY_FI(9) Hardware Interfaces PCI_CREATE_LEGACY_FI(9)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 propogate the error to the caller as it is ok to set up the PCI bus without these files.

pcitweak - read/write PCI config space
SYNOPSIS
pcitweak -l
pcitweak -r PCI-ID [-b|-h] offset
pcitweak -w PCI-ID [-b|-h] offset value
DESCRIPTION
Pcitweak is a utility that can be used to examine or change registers in the PCI configuration space. On most platfoms pcitweak can only
be run by the root user.
OPTIONS -l Probe the PCI buses and print a line for each detected device. Each line contains the bus location (bus:device:function), chip
vendor/device, card (subsystem) vendor/card, revision, class and header type. All values printed are in hexadecimal.
-r PCI-ID
Read the PCI configuration space register at offset for the PCI device at bus location PCI-ID. PCI-ID should be given in the form
bus:device:function, with each value in hexadecimal. By default, a 32-bit register is read.
-w PCI-ID
Write value to the PCI configuration space register at offset for the PCI device at bus location PCI-ID. PCI-ID should be given in
the form bus:device:function, with each value in hexadecimal. By default, a 32-bit register is written.
-b Read or write an 8-bit value (byte).
-h Read or write a 16-bit value (halfword).

Hi all,
I want to create a new user and grant him ONLY transfer files access to a specific directory where he can only upload and read the files. He should be restricted to this activity only.
