NAME

       lspnp - list Plug and Play BIOS device nodes and resources

SYNOPSIS

       lspnp [-b] [-v[v]] [device ...]

DESCRIPTION

       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.

OPTIONS

       -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
              interface.

       -v     Selects more verbose output.  Can be used more than once.
