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.
