help
Pass additional commands to the kernel.
config ETRAX_WATCHDOG
bool "Enable ETRAX watchdog"
help
Enable the built-in watchdog timer support on ETRAX based embedded
network computers.
config ETRAX_WATCHDOG_NICE_DOGGY
bool "Disable watchdog during Oops printouts"
depends on ETRAX_WATCHDOG
help
By enabling this you make sure that the watchdog does not bite while
printing oopses. Recommended for development systems but not for
production releases.
config ETRAX_FAST_TIMER
bool "Enable ETRAX fast timer API"
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.
