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