  55           network computers.

  60         help
  61           By enabling this you make sure that the watchdog does not bite while
  62           printing oopses. Recommended for development systems but not for
  63           production releases.

  68          This options enables the API to a fast timer implementation using
  69          timer1 to get sub jiffie resolution timers (primarily one-shot
  70          timers).
  71          This is needed if CONFIG_ETRAX_SERIAL_FAST_TIMER is enabled.

  73 config PREEMPT
  74         bool "Preemptible Kernel"
  75         help
  76           This option reduces the latency of the kernel when reacting to
  77           real-time or interactive events by allowing a low priority process to
  78           be preempted even if it is in kernel mode executing a system call.
  79           This allows applications to run more reliably even when the system is
  80           under load.
  81
  82           Say Y here if you are building a kernel for a desktop, embedded
  83           or real-time system.  Say N if you are unsure.
