53 By enabling this you make sure that the watchdog does not bite while
54 printing oopses. Recommended for development systems but not for
55 production releases.

57config ETRAX_FAST_TIMER
58 bool "Enable ETRAX fast timer API"
59 help
60 This options enables the API to a fast timer implementation using
61 timer1 to get sub jiffie resolution timers (primarily one-shot
62 timers).
63 This is needed if CONFIG_ETRAX_SERIAL_FAST_TIMER is enabled.
64
65config PREEMPT
66 bool "Preemptible Kernel"
67 help
68 This option reduces the latency of the kernel when reacting to
69 real-time or interactive events by allowing a low priority process to
70 be preempted even if it is in kernel mode executing a system call.
71 This allows applications to run more reliably even when the system is
72 under load.
73
74 Say Y here if you are building a kernel for a desktop, embedded
75 or real-time system. Say N if you are unsure.
