biosdevname
BIOSDEVNAME(1) General Commands Manual BIOSDEVNAME(1)
NAME
biosdevname - give BIOS-given name of a device
SYNOPSIS
biosdevname [options] [args]...
DESCRIPTION
biosdevname takes a kernel device name as an argument, and returns the BIOS-given name it "should" be.
OPTIONS
-i, --interface
Treat [args] as ethernet devs
-d, --debug
Enable debugging
-p, --policy [physical|all_ethN]
-P, --prefix [string]
string use for embedded NICs in the physical policy (default=em)
-x, --nopirq
Do not use $PIR table for mapping PCI device to slot. Some BIOS have incorrect values.
-s, --smbios [x.y]
Require minimum SMBIOS version x.y
POLICIES
The physical policy is the current default. However, when invoking biosdevname in udev rules, one should always specify the policy you
want, as the default has changed over time.
The physical policy uses the following scheme:
em<port>[_<virtual instance>]
for embedded NICs
p<slot>p<port>[_<virtual instance>]
for cards in PCI slots
The all_ethN policy makes a best guess at what the device order should be, with embedded devices first, PCI cards in ascending slot
order, and ports in ascending PCI bus/device/function order breadth-first. However, this policy does not work if your PCI devices
are hot-plugged or hot-pluggable, including the virtual functions on an SR-IOV device. In a hot-plug scenario, each separate udev
instance will be invoked in parallel, while the device tree is still being populated with new devices. Each udev instance will see
a different PCI tree, and thus cannot provide consistent enumeration. Use of this policy should be limited to only scenarios where
all PCI devices are present at boot (cold-plug).
EXIT CODES
Returns 0 on success, with BIOS-suggested name printed to stdout.
Returns 1 on provided device name lookup failure.
Returns 2 if system BIOS does not provide naming information. biosdevname requires system BIOS to provide naming information, either via
SMBIOS or sysfs files.
Returns 3 if not run as root but requires root privileges.
Returns 4 if running in a virtual machine.

RELATED PROGRAMS
The dmidecode package contains two tools useful for debugging BIOS features that biosdevname uses, specifically dmidecode to read the
SMBIOS Type 9 and Type 41 tables, and biosdecode to read the PCI IRQ Routing Table. Please include the output of each of these programs in
any bug reports.
