Verification Via The /proc Directory

• The /proc directory is a virtual directory, allowing direct interaction with the running Linux Kernel.
• When we try to print one of its files, the Kernel generates its contents on-the-fly. There are no real disk files under this directory.
• Some files interesting for Hardware diagnostics (view them with cat <file>):
  • /proc/interrupts - a list of interrupt numbers (IRQs) currently in use by different Drivers.
  • /proc/ioports - a list of I/O addresses currently in use by Drivers.
  • /proc/pci - info about PCI Devices.
  • /proc/cpuinfo - info about our CPU.
