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.

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’ -- simulate configuration space accesses instead  of
              really  doing  them.   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 standalone.

DEVICE SELECTION

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

       -s [[<bus>]:][<slot>][.[<func>]]
              Select  devices  in  specified  bus,  slot  and  function.  Each
              component  of  the  device  address can be omitted or set as "*"
              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
              busses and ".4" selects only fourth function of each device.

       -d [<vendor>]:[<device>]
              Select  devices  with  specified vendor and device ID. Both ID’s
              are given in hexadecimal and may be  omitted  or  given  as  "*"
              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 you would use
       to query the register and values is a comma-separated  list  of  values
       you want to write starting with the given address.

REGISTER NAMES

       setpci  knows  the  following configuration register names. See PCI bus
       specs for their precise meaning or consult /usr/include/linux/pci.h for
       few comments.

PCILIB OPTIONS

       The  PCI  utilities  use PCILIB (a portable library providing platform-
       independent functions for PCI configuration space access)  to  talk  to
       the PCI cards. The following options control parameters of the library,
       especially what access method it uses.  By  default,  PCILIB  uses  the
       first  available access method and displays no debugging messages. Each
       switch is accompanied by a  list  of  hardware/software  configurations
       it’s supported in.

       -P <dir>
              Force  use  of  Linux  /proc/bus/pci style configuration access,
              using <dir> instead of /proc/bus/pci. (Linux 2.1 or newer only)

       -H1    Use direct hardware access via Intel configuration mechanism  1.
              (i386 and compatible only)

       -H2    Use  direct hardware access via Intel configuration mechanism 2.
              Warning: This method is able to address only first 16 devices on
              any bus and it seems to be very unrealiable in many cases. (i386
              and compatible only)

       -S     Use PCI access syscalls. (Linux on Alpha and UltraSparc only)

       -F <file>
              Extract all information from given  file  containing  output  of
              lspci  -x. This is very useful for analysis of user-supplied bug
              reports, because you can display the hardware  configuration  in
              any  way  you want without disturbing the user with requests for
              more dumps. (All systems)

       -G     Increase debug level of the library. (All systems)

EXAMPLES

       ‘setpci -d *:* latency_timer=40’ sets  the  latency  timer  to  64  (40
       hexadecimal).

       ‘setpci  -s  0  device_id vendor_id’ lists ID’s of devices in slot 0 in
       all busses.

       ‘setpci -s 12:3.4 3c.l=1,2,3’ writes longword 1 to register  3c,  2  to
       register  3d and 3 to register 3e of device at bus 12, slot 3, function
       4.
