LSDEV(8) Linux System Manual LSDEV(8)
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 chan‐
nels.
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 exam‐
ined 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 exam‐
ple).
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.

作用
lsdev 的使用比較簡單，不需要參數，它能夠獲取你電腦上已安裝的硬件信息，它主要從 /proc/interrupts、/proc/ioports 、/proc/dma 文件中讀取你所要的信息。
bug
當使用 lsdev 的時候，如果一個設備同時有多個名字，例如鍵盤keyboard在 /proc/ioports 中命名爲 kbd，而在 /proc/interrupts 中則命名爲 keyboard ，而 lsdev 並不能識別出兩者均爲同一個設備。但其實這並不是 lsdev 的bug，與內核有關。
