NAME

SYNOPSIS

10       lsdev

DESCRIPTION

14       lsdev gathers information about your computer's installed hardware from
15       the interrupts, ioports and dma files in the /proc directory, thus giv‐
16       ing  you a quick overview of which hardware uses what I/O addresses and
17       what IRQ and DMA channels.

FILES

25       /proc/interrupts
26              IRQ channels.

29       /proc/ioports
30              I/O memory addresses.
31

33       /proc/dma
34              DMA channels.

BUGS

38       lsdev can't always figure out which lines in the three  examined  files
39       refer  to  one  and  the same device, because these files sometimes use
40       different names for the same piece of hardware. For  example,  in  some
41       kernels  the  keyboard  is referred to as `kbd' in /proc/ioports and as
42       `keyboard' in /proc/interrupts.  This should be fixed  in  the  kernel,
43       not in lsdev (as has indeed happened for this particular example).
44
45       The program does however try to match lines by stripping anything after
46       a space or open parenthesis from the name, so that  e.g.  the  `serial'
47       lines   from   /proc/interrupts  match  the  `serial(set)'  lines  from
48       /proc/ioports.  This attempt at DWIM  might  be  considered  a  bug  in
49       itself.
50
51       This  program only shows the kernel's idea of what hardware is present,
52       not what's actually physically available.
