14 This utility presents a formatted interpretation of the contents of the
15 .I /sys/bus/pnp/devices
18 tree. The default output is a list of Plug and Play device node
19 names, product identifiers, and descriptions. Verbose output
21 includes resource allocations (IO ports, memory, interrupts, and DMA
22 channels) for each device. Very verbose output
24 includes lists of possible resources, various configuration flags, and
25 product identifiers for compatible devices.
27 The output can be limited to one or more specific device nodes by
28 specifying their node names on the command line. By
29 default, current (dynamic) device configuration information is
32 option, the boot (static) configuration is shown.
36 Boot mode: read device resource information that will be used at next
37 boot (as opposed to current resource info). This is supported only on
