"Linux/CRIS Kernel Configuration"


 * Option: MMU
 * Kernel Versions: 2.6.15.6 ...
 * (on/off)
 * default y


 * Option: UID16
 * Kernel Versions: 2.6.15.6 ...
 * (on/off)
 * default y


 * Option: RWSEM_GENERIC_SPINLOCK
 * Kernel Versions: 2.6.15.6 ...
 * (on/off)
 * default y


 * Option: RWSEM_XCHGADD_ALGORITHM
 * Kernel Versions: 2.6.15.6 ...
 * (on/off)


 * Option: GENERIC_CALIBRATE_DELAY
 * Kernel Versions: 2.6.15.6 ...
 * (on/off)
 * default y


 * Option: CRIS
 * Kernel Versions: 2.6.15.6 ...
 * (on/off)
 * default y


 * Option: Howto configure the Linux kernel/init

General setup

 * Option: Howto configure the Linux kernel/fs.binfmt"

"Kernel command line"
 * Option: ETRAX_CMDLINE
 * Kernel Versions: 2.6.15.6 ...
 * default "root=/dev/mtdblock3"
 * Pass additional commands to the kernel.


 * Option: ETRAX_WATCHDOG
 * Kernel Versions: 2.6.15.6 ...
 * (on/off) Enable ETRAX watchdog
 * Enable the built-in watchdog timer support on ETRAX based embedded network computers.


 * Option: ETRAX_WATCHDOG_NICE_DOGGY
 * Kernel Versions: 2.6.15.6 ...
 * (on/off) Disable watchdog during Oops printouts
 * depends on ETRAX_WATCHDOG
 * By enabling this you make sure that the watchdog does not bite while printing oopses. Recommended for development systems but not for production releases.


 * Option: ETRAX_FAST_TIMER
 * Kernel Versions: 2.6.15.6 ...     bool Enable ETRAX fast timer API      help        This options enables the API to a fast timer implementation usingtimer1 to get sub jiffie resolution timers (primarily one-shottimers).This is needed if CONFIG_ETRAX_SERIAL_FAST_TIMER is enabled.


 * Option: PREEMPT
 * Kernel Versions: 2.6.15.6 ...
 * (on/off) Preemptible Kernel
 * 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.
