Usage: setpci [<options>] (<device>+ <reg>[=<values>]*)*
General options:
-f Don't complain if there's nothing to do
-v Be verbose
-D List changes, don't commit them
-r Use raw access without bus scan if possible
--dumpregs Dump all known register names and exit
PCI access options:
-A <method> Use the specified PCI access method (see `-A help' for a list)
-O <par>=<val> Set PCI access parameter (see `-O help' for a list)
-G Enable PCI access debugging
-H <mode> Use direct hardware access (<mode> = 1 or 2)
Setting commands:
<device>: -s [[[<domain>]:][<bus>]:][<slot>][.[<func>]]
-d [<vendor>]:[<device>]
<reg>: <base>[+<offset>][.(B|W|L)][@<number>]
<base>: <address>
<named-register>
[E]CAP_<capability-name>
