if memory reclamation is of high priority). If CONFIG_SCHED_WORKQUEUE
is enabled, then the following options can also be used:
CONFIG_SCHED_WORKPRIORITY - The execution priority of the worker
thread. Default: 50
thread. Default: 192
CONFIG_SCHED_WORKPERIOD - How often the worker thread checks for
work in units of microseconds. Default: 50*1000 (50 MS).
CONFIG_SCHED_WORKSTACKSIZE - The stack size allocated for the worker
thread. Default: CONFIG_IDLETHREAD_STACKSIZE.
CONFIG_SIG_SIGWORK - The signal number that will be used to wake-up
the worker thread. Default: 4
CONFIG_SCHED_LPWORK. If CONFIG_SCHED_WORKQUEUE is defined, then a single
work queue is created by default. If CONFIG_SCHED_LPWORK is also defined
then an additional, lower-priority work queue will also be created. This
lower priority work queue is better suited for more extended processing
(such as file system clean-up operations)
CONFIG_SCHED_LPWORKPRIORITY - The execution priority of the lower priority
worker thread. Default: 50
CONFIG_SCHED_LPWORKPERIOD - How often the lower priority worker thread
checks for work in units of microseconds. Default: 50*1000 (50 MS).
CONFIG_SCHED_LPWORKSTACKSIZE - The stack size allocated for the lower
priority worker thread. Default: CONFIG_IDLETHREAD_STACKSIZE.
CONFIG_SCHED_WAITPID - Enables the waitpid() API
CONFIG_SCHED_ATEXIT - Enables the atexit() API
CONFIG_SCHED_ATEXIT_MAX - By default if CONFIG_SCHED_ATEXIT is
