lsdev - display information about installed hardware
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.
I/O memory addresses.
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
This program only shows the kernel’s idea of what hardware is present,
not what’s actually physically available.
