The PCI Utilities package contains a library for portable access to
|
|
PCI bus configuration registers and several utilities based on this
|
|
library.
|
|
|
|
Currently, pciutils work on all versions of Linux and they also have
|
|
somewhat experimental support for OpenBSD, FreeBSD, NetBSD, AIX, GNU
|
|
Hurd and Solaris/x86. It should be very easy to add support for other
|
|
systems as well (volunteers wanted; if you want to try that, I'll be
|
|
very glad to see the patches and include them in the next version).
|
|
|
|
The utilities include: (See manual pages for more details)
|
|
|
|
- lspci: displays detailed information about all PCI buses and
|
|
devices.
|
|
|
|
- setpci: allows to read from and write to PCI device configuration
|
|
registers. For example, you can adjust the latency timers with it.
|
|
CAUTION: There is a couple of dangerous points and caveats, please
|
|
read the manual page first!
|
|
|
|
- update-pciids: download the current version of the pci.ids file.
|
|
|
|
On OpenBSD you need to set sysctl machdep.allowaperture=2 in
|
|
/etc/sysctl.conf, and run lspci and setpci as root.
