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 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.
