lspnp - list Plug and Play BIOS device nodes and resources
lspnp [-b] [-v[v]] [device ...]
This utility presents a formatted interpretation of the contents of the
/sys/bus/pnp/devices or /proc/bus/pnp tree. The default output is a
list of Plug and Play device node names, product identifiers, and
descriptions. Verbose output (-v) includes resource allocations (IO
ports, memory, interrupts, and DMA channels) for each device. Very
verbose output (-vv) includes lists of possible resources, various
configuration flags, and product identifiers for compatible devices.
The output can be limited to one or more specific device nodes by
specifying their node names on the command line. By default, current
(dynamic) device configuration information is displayed; with the -b
option, the boot (static) configuration is shown.
-b Boot mode: read device resource information that will be used at
next boot (as opposed to current resource info). This is
supported only on kernels that provide the old /proc/bus/pnp
-v Selects more verbose output. Can be used more than once.
A database of known Plug and Play device ID’s.
