3 | .SH NAME | |
4 | lspci \- configure PCI devices | |
5 | .SH SYNOPSIS | |
6 | .B setpci | |
7 | .RB [ options ] | |

11 | .SH DESCRIPTION | |
12 | .PP | |
13 | .B setpci | |
14 | is a utility for querying and configuring PCI devices. It requires Linux kernel 2.1.82 | |
15 | or newer as it uses the /proc/bus/pci interface. | |
16 | .PP | |
17 | All numbers are entered in hexadecimal notation. | |
18 | ||
19 | .SH OPTIONS | |
20 | .TP | |
21 | .B -v | |
22 | Tells | |
23 | .I setpci | |
24 | to be verbose and display detailed information about configuration space accesses. | |
25 | .TP | |
26 | .B -f | |
27 | Tells | |
28 | .I lspci | |
29 | not to complain when there's nothing to do (when no devices are selected). | |
30 | This option is intended for use in widely-distributed configuration scripts | |
31 | where it's uncertain whether the device in question is present in the machine | |
32 | or not. | |
33 | .TP | |
34 | .B -D | |
35 | `Demo mode' -- simulate configuration space accesses instead of really doing them. | |
36 | It's useful to try | |
37 | .B setpci -vD | |
38 | to see what your complex sequence of | |
39 | .B setpci | |
40 | operations does before you actually execute it. | |
41 | ||
42 | .SH DEVICE SELECTION | |
43 | .PP | |
44 | Before each sequence of operations you need to select which devices you wish that | |
45 | operation to affect. | |
46 | .TP | |
47 | .B -s [[<bus>]:][<slot>][.[<func>]] | |
48 | Select devices in specified bus, slot and function. Each component of the device | |
49 | address can be omitted or set as "*" meaning "any value". All numbers are | |
50 | hexadecimal. E.g., "0:" means all devices on bus 0, "0" means all functions of device 0 | |
51 | on any bus, "0.3" selects third function of device 0 on all busses and ".4" selects only | |
52 | fourth function of each device. | |
53 | .TP | |
54 | .B -d [<vendor>]:[<device>] | |
55 | Select devices with specified vendor and device ID. Both ID's are given in | |
56 | hexadecimal and may be omitted or given as "*" meaning "any value". | |
57 | ||
58 | .SH OPERATIONS | |
59 | .PP | |
60 | To query value of a configuration register, just name it (either by typing its name or | |
61 | by typing register address with optional | |
62 | .BR .B , | |
63 | .B .W | |
64 | or | |
65 | .B .L | |
66 | suffix specifying register width as byte, word or longword). | |
67 | .PP | |
68 | To set a register, write | |
69 | .BR reg = values | |
70 | where | |
71 | .B reg | |
72 | is the same you would use to query the register and | |
73 | .B values | |
74 | is a comma-separated list of values you want to write starting with the given | |
75 | address. | |
76 | ||
77 | .SH REGISTER NAMES | |
78 | .PP | |
79 | .B setpci | |
80 | knows the following configuration register names. See PCI bus specs for their precise | |
81 | meaning or consult | |
82 | .B /usr/include/linux/pci.h | |
83 | for few comments. | |

151 | .SH EXAMPLES | |
152 | .PP | |
153 | `setpci -d *:* latency_timer=40' sets the latency timer to 64 (40 hexadecimal). | |
154 | .PP | |
155 | `setpci -s 0 device_id vendor_id' lists ID's of devices in slot 0 in all busses. | |
156 | .PP | |
157 | `setpci -s 12:3.4 34.l=1,2,3' writes longword 1 to register 34, 2 to register 35 | |
158 | and 3 to register 35 of device at bus 12, slot 3, function 4. | |
