Know about installed hardware resources


If you want to know about installed hardware and their resources like io ports, irq and DMA channel then you may go through /proc file system to get that all informations.

To know about

  • io ports see /proc/ioports
  • irq see /proc/interrupts
  • DMA channels see /proc/dma

But we have got lsdev to gather all this info at single place.

To install
$ sudo apt-get install procinfo

$ lsdev
