54 string "Kernel command line"
55 default "root=/dev/mtdblock3"
57 Pass additional commands to the kernel.
60 bool "Enable ETRAX watchdog"
62 Enable the built-in watchdog timer support on ETRAX based embedded
65 config ETRAX_WATCHDOG_NICE_DOGGY
66 bool "Disable watchdog during Oops printouts"
67 depends on ETRAX_WATCHDOG
69 By enabling this you make sure that the watchdog does not bite while
70 printing oopses. Recommended for development systems but not for
73 config ETRAX_FAST_TIMER
74 bool "Enable ETRAX fast timer API"
76 This options enables the API to a fast timer implementation using
77 timer1 to get sub jiffie resolution timers (primarily one-shot
79 This is needed if CONFIG_ETRAX_SERIAL_FAST_TIMER is enabled.
82 bool "Preemptible Kernel"
84 This option reduces the latency of the kernel when reacting to
85 real-time or interactive events by allowing a low priority process to
86 be preempted even if it is in kernel mode executing a system call.
87 This allows applications to run more reliably even when the system is
90 Say Y here if you are building a kernel for a desktop, embedded
91 or real-time system. Say N if you are unsure.
