config BOOT_BANNER
|
|
bool
|
|
prompt "Boot banner"
|
|
default n
|
|
select PRINTK
|
|
help
|
|
This option outputs a banner to the console device during boot up. It
|
|
also embeds a date & time stamp in the kernel and in each USAP image.
|
|
|
|
config INT_LATENCY_BENCHMARK
|
|
bool
|
|
prompt "Interrupt latency metrics [EXPERIMENTAL]"
|
|
default n
|
|
depends on ARCH="x86" && EXPERIMENTAL
|
|
help
|
|
This option enables the tracking of interrupt latency metrics;
|
|
the exact set of metrics being tracked is platform-dependent.
|
|
Tracking begins when intLatencyInit() is invoked by an application.
|
|
The metrics are displayed (and a new sampling interval is started)
|
|
each time intLatencyShow() is called thereafter.
|

|
|
config MAIN_STACK_SIZE
|
|
int
|
|
prompt "Background task stack size (in bytes)"
|
|
default 1024
|
|
help
|
|
This option specifies the size of the stack used by the kernel's
|
|
background task, whose entry point is main().
|
|
|
|
config ISR_STACK_SIZE
|
|
int
|
|
prompt "ISR and initialization stack size (in bytes)"
|
|
default 2048
|
|
help
|
|
This option specifies the size of the stack used by interrupt
|
|
service routines (ISRs), and during nanokernel initialization.
|
|
|
|
config THREAD_CUSTOM_DATA
|
|
bool
|
|
prompt "Task and fiber custom data"
|
|
default n
|
|
help
|
|
This option allows each task and fiber to store 32 bits of custom data,
|
|
which can be accessed using the sys_thread_custom_data_xxx() APIs.
|
|
|
|
config NANO_TIMEOUTS
|
|
bool
|
|
prompt "Enable timeouts on nanokernel objects"
|
|
default n
|
|
depends on SYS_CLOCK_EXISTS
|
|
help
|
|
Allow fibers and tasks to wait on nanokernel objects with a timeout, by
|
|
enabling the nano_xxx_wait_timeout APIs, and allow fibers to sleep for a
|
|
period of time, by enabling the fiber_sleep API.
|
|
|
|
config NANO_TIMERS
|
|
bool
|
|
prompt "Enable nanokernel timers"
|
|
default y if NANOKERNEL
|
|
default n
|
|
depends on SYS_CLOCK_EXISTS
|
|
help
|
|
Allow fibers and tasks to wait on nanokernel timers, which can be
|
|
accessed using the nano_timer_xxx() APIs.
