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