NAME


       setpci - configure PCI devices

 

SYNOPSIS


       setpci [options] devices operations...


 

DESCRIPTION






       setpci is a utility for querying and configuring PCI devices.

       All numbers are entered in hexadecimal notation.

       Root  privileges  are  necessary  for  almost all operations, excluding
       reads of the standard header of the configuration space on some operat-
       ing systems.  Please see lspci(8) for details on access rights.


 

OPTIONS


   General options
       -v     Tells  setpci  to  be  verbose  and display detailed information
              about configuration space accesses.

       -f     Tells setpci not to complain when there's nothing to do (when no
              devices  are  selected).   This  option  is  intended for use in
              widely-distributed configuration scripts  where  it's  uncertain
              whether the device in question is present in the machine or not.

       -D     `Demo mode' -- don't write anything to the configuration  regis-
              ters.   It's  useful  to try setpci -vD to see what your complex
              sequence of setpci operations does before you  actually  execute
              it.

       --version
              Shows setpci version. This option should be used stand-alone.


   PCI access options
       The  PCI  utilities  use  the  PCI  library to talk to PCI devices (see
       pcilib(7) for details). You can use the following options to  influence
       its behavior:

       -A 
              The  library  supports  a  variety  of methods to access the PCI
              hardware.  By default, it uses the first  access  method  avail-
              able, but you can use this option to override this decision. See
              -A help for a list of available methods and their  descriptions.

       -O =
              The  behavior  of  the  library  is  controlled by several named
              parameters.  This option allows to set the value of any  of  the
              parameters. Use -O help for a list of known parameters and their
              default values.

       -H1    Use direct hardware access via Intel configuration mechanism  1.
              (This is a shorthand for -A intel-conf1.)

       -H2    Use  direct hardware access via Intel configuration mechanism 2.
              (This is a shorthand for -A intel-conf2.)

       -G     Increase debug level of the library.


 

DEVICE SELECTION


       Before each sequence of operations you need to select which devices you
       wish that operation to affect.

       -s [[[[]:]]:][][.[]]
              Show  only devices in the specified domain (in case your machine
              has several host bridges, they can either  share  a  common  bus
              number  space  or  each  of them can address a PCI domain of its
              own; domains are numbered from 0 to ffff), bus (0 to  ff),  slot
              (0  to  1f) and function (0 to 7).  Each component of the device
              address can be omitted or set to "*", both meaning "any  value".
              All  numbers  are  hexadecimal.  E.g., "0:" means all devices on
              bus 0, "0" means all functions of device 0  on  any  bus,  "0.3"
              selects  third  function of device 0 on all buses and ".4" shows
              only the fourth function of each device.

       -d []:[]
              Select devices with specified vendor and device  ID.  Both  ID's
              are  given  in  hexadecimal  and may be omitted or given as "*",
              both meaning "any value".


 

OPERATIONS


       To query value of a configuration register, just  name  it  (either  by
       typing  its  name or by typing register address with optional .B, .W or
       .L suffix specifying register width as byte, word or longword).

       To set a register, write reg=values where reg is the same as you  would
       use  to query the register and values is a comma-separated list of val-
       ues you want to write starting with the given address. Each value to be
       written  can  be  specified  either  as  a  hexadecimal  number or as a
       bits:mask pair which causes the bits corresponding to  binary  ones  in
       the mask to be changed to values of the corresponding bits in the bits


 

REGISTER NAMES


       setpci  knows  the  following configuration register names. See PCI bus
       specifications  for  their  precise  meaning  or  consult  header.h  or
       /usr/include/linux/pci.h for a couple of comments.
