lsdev




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  key­
       board  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.
