76 By enabling this you make sure that the watchdog does not bite while
77 printing oopses. Recommended for development systems but not for
78 production releases.

80config ETRAX_FAST_TIMER
81 bool "Enable ETRAX fast timer API"
82 help
83 This options enables the API to a fast timer implementation using
84 timer1 to get sub jiffie resolution timers (primarily one-shot
85 timers).
86 This is needed if CONFIG_ETRAX_SERIAL_FAST_TIMER is enabled.
87
88config PREEMPT
89 bool "Preemptible Kernel"
90 help
91 This option reduces the latency of the kernel when reacting to
92 real-time or interactive events by allowing a low priority process to
93 be preempted even if it is in kernel mode executing a system call.
94 This allows applications to run more reliably even when the system is
95 under load.
96
97 Say Y here if you are building a kernel for a desktop, embedded
98 or real-time system. Say N if you are unsure.
