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 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).

Hi all,
I have customized tool that displays PCI device information (something similar to the linux - "lspci") . Now, I need to display information only on "plug-in" cards. Are there any ways to distinguish between "on-board" PCI device and a PCI "plug-in" card.
Thanks,

Hi All,
Probe is not returning the Device ID, while device (PCI Express-to-PCI Bridge) is already detected by "lspci". I checked this with printing all the device ID which has been detected.
Can anyone give me any suggestion or solution.
Thanks (in advance)

Hey guys,
I know that in normal desktop computers, the CPU interfaces the video card, sound card, USB card, etc by the PCI slots but what about laptops? I've heard that laptops also have a PCI bus even though do don't have a PCI slot so does this mean that the same address space that would... (4 Replies)
