NAME

       scanpci - scan/probe PCI buses

SYNOPSIS

       scanpci [-v12OfV]

DESCRIPTION

       Scanpci	is a utility that can be used to scan PCI buses and report information about the configuration space settings for each PCI device.
       On most platforms, scanpci can only be run by the root user.

OPTIONS

       -v      Print the configuration space information for each device in a verbose format.  Without this option, only a  brief  description	is
	       printed for each device.

       -1      Use PCI config type 1.

       -2      Use PCI config type 2.

       -f      Used in conjunction with the above two options, this forces the specified configuration type to be used for config space access.

       -O      Use the OS's PCI config space access mechanism to access the PCI config space (when available).

       -V n    Set the verbosity level to n for the internal PCI scanner.  This is primarily for debugging use.

NAME

       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 platforms 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).
