# lsdev(8)

display information about installed hardware

## 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.
