PCI Utilities 3.0.3 (Default branch)
The PCI Utilities package contains various utilities dealing with the PCI bus, and also a library for portable access to PCI configuration registers. It includes `lspci' for listing all PCI devices (very useful for debugging of both kernel and device drivers) and `setpci' for manual configuration of PCI devices.License: GNU General Public License (GPL)Changes:
The decoding of several PCI-X capabilities was added. Printing of MSI capabilities was added. "lspci -k" now displays the subsystem ID too, making "-k" show everything needed to identify the device and the available drivers. The pci.ids file was updated. Compatibility problems with various default settings of wget are now worked around. A Cygwin port was added. Several other bugs were fixed.Image

PCITWEAK(1)						      General Commands Manual						       PCITWEAK(1)

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 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).
