setpci !!!setpci NAME SYNOPSIS DESCRIPTION OPTIONS DEVICE SELECTION OPERATIONS REGISTER NAMES PCILIB OPTIONS EXAMPLES SEE ALSO AUTHOR ---- !!NAME setpci - configure PCI devices !!SYNOPSIS __setpci__ [[__options__] __devices operations__... !!DESCRIPTION __setpci__ is a utility for querying and configuring PCI devices. To make use of all the features of this program, you need to have Linux kernel 2.1.82 or newer which supports the /proc/bus/pci interface. With older kernels, the PCI utilities have to use direct hardware access which is available only to root and it suffers from numerous race conditions and other problems. 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 [[[[__ Select devices in specified bus, slot and function. Each component of the device address can be omitted or set as __-d [[__ Select devices with specified vendor and device ID. Both ID's are given in hexadecimal and may be omitted or given as !!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.

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 __ Use Linux 2.1 style configuration access to directory ____ 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 __ 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. !!SEE ALSO lspci(8) !!AUTHOR The Linux PCI Utilities are maintained by Martin Mares ----
