NAME

       lsdev - display information about installed hardware

SYNOPSIS

       lsdev

DESCRIPTION

       lsdev  gathers  information  about your computer's installed hardware from the interrupts,
       ioports and dma files in the /proc directory, thus giving you a quick  overview  of  which
       hardware 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
       hardware.  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.
