production releases.

help

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

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