LSDEV(8)                                 Linux System Manual                                LSDEV(8)



NAME
       lsdev - display information about installed hardware


SYNOPSIS
       lsdev


DESCRIPTION
       lsdev  gathers  information about your computer's installed hardware from the interrupts, io‐‐
       ports and dma files in the /proc directory, thus giving you a quick overview of  which  hard‐
       ware uses what I/O addresses and what IRQ and DMA channels.


OPTIONS
       None.


FILES
       /proc/interrupts
              IRQ channels.


       /proc/ioports
              I/O memory addresses.


       /proc/dma
              DMA channels.


BUGS
       lsdev  can't  always  figure out which lines in the three examined files refer to one and the
       same device, because these files sometimes use different names for the same  piece  of  hard‐
       ware.  For example, in some kernels the keyboard is referred to as `kbd' in /proc/ioports and
       as `keyboard' in /proc/interrupts.  This should be fixed in the kernel, not in lsdev (as  has
       indeed happened for this particular example).

       The  program  does  however  try  to  match lines by stripping anything after a space or open
       parenthesis from the name, so that e.g. the `serial' lines from  /proc/interrupts  match  the
       `serial(set)'  lines  from  /proc/ioports.  This attempt at DWIM might be considered a bug in
       itself.

       This program only shows the kernel's idea of what hardware is present,  not  what's  actually
       physically available.
