This setting - may be defined to inform NuttX that the processor hardware is providing - system timer interrupts at some interrupt interval other than 10 msec. - -config RR_INTERVAL - int "Round robin timeslice (MSEC)" - default 0 - ---help--- - The round robin timeslice will be set this number of milliseconds; - Round robin scheduling can be disabled by setting this value to zero. - -config SCHED_INSTRUMENTATION - bool "Monitor system performance" - default n - ---help--- - Enables instrumentation in scheduler to monitor system performance. - If enabled, then the board-specific logic must provide the following - functions (see include/sched.h): - - void sched_note_start(FAR _TCB *tcb); - void sched_note_stop(FAR _TCB *tcb); - void sched_note_switch(FAR _TCB *pFromTcb, FAR _TCB *pToTcb); - -config TASK_NAME_SIZE - int "Maximum task name size" - default 32 - ---help--- - Spcifies that maximum size of a task name to save in the TCB. - Useful if scheduler instrumentation is selected. Set to zero to - disable. - -config SCHED_HAVE_PARENT - bool "Support parent/child task relationships" - default n - ---help--- - Remember the ID of the parent task when a new child task is - created. This support enables some additional features (such as - SIGCHLD) and modifies the behavior of other interfaces. For - example, it makes waitpid() more standards complete by restricting - the waited-for tasks to the children of the caller. Default: - disabled. - -config SCHED_CHILD_STATUS - bool "Retain child exit status" - default n - depends on SCHED_HAVE_PARENT - ---help--- - If this option is selected, then the exit status of the child task - will be retained after the child task exits. This option should be - selected if you require knowledge of a child process' exit status. - Without this setting, wait(), waitpid() or waitid() may fail. For - example, if you do: - - 1) Start child task - 2) Wait for exit status (using wait(), waitpid(), or waitid()). - - This can fail because the child task may run to completion before - the wait begins. There is a non-standard work-around in this case: - The above sequence will work if you disable pre-emption using - sched_lock() prior to starting the child task, then re-enable pre- - emption with sched_unlock() after the wait completes. This works - because the child task is not permitted to run until the wait is in - place. - - The standard solution would be to enable SCHED_CHILD_STATUS. In - this case the exit status of the child task is retained after the - child exits and the wait will successful obtain the child task's - exit status whether it is called before the child task exits or not. - - Warning: If you enable this feature, then your application must - either (1) take responsibility for reaping the child status with wait(), - waitpid(), or waitid(), or (2) suppress retention of child status. - If you do not reap the child status, then you have a memory leak and - your system will eventually fail. - - Retention of child status can be suppressed on the parent using logic like: - - struct sigaction sa; - - sa.sa_handler = SIG_IGN; - sa.sa_flags = SA_NOCLDWAIT; - int ret = sigaction(SIGCHLD, &sa, NULL); - -config PREALLOC_CHILDSTATUS - int "Number of pre-allocated child status" - default 0 - depends on SCHED_CHILD_STATUS - ---help--- - To prevent runaway child status allocations and to improve - allocation performance, child task exit status structures are pre- - allocated when the system boots. This setting determines the number - of child status structures that will be pre-allocated. If this - setting is not defined or if it is defined to be zero then a value - of 2*MAX_TASKS is used. - - Note that there cannot be more that CONFIG_MAX_TASKS tasks in total. - However, the number of child status structures may need to be - significantly larger because this number includes the maximum number - of tasks that are running PLUS the number of tasks that have exit'ed - without having their exit status reaped (via wait(), waitid(), or - waitpid()). - - Obviously, if tasks spawn children indefinitely and never have the - exit status reaped, then you may have a memory leak! If you enable - the SCHED_CHILD_STATUS feature, then your application must take - responsibility for either (1) reaping the child status with wait(), - waitpid(), or waitid() or it must (2) suppress retention of child - status. Otherwise, your system will eventually fail. - - Retention of child status can be suppressed on the parent using logic like: - - struct sigaction sa; - - sa.sa_handler = SIG_IGN; - sa.sa_flags = SA_NOCLDWAIT; - int ret = sigaction(SIGCHLD, &sa, NULL); - -config DEBUG_CHILDSTATUS - bool "Enable Child Status Debug Output" - default n - depends on SCHED_CHILD_STATUS && DEBUG - ---help--- - Very detailed...

If - set, all sockets will appear to be closed in the new task. - -config SCHED_WORKQUEUE - bool "Enable worker thread" - default n - depends on !DISABLE_SIGNALS - ---help--- - Create a dedicated "worker" thread to handle delayed processing from interrupt - handlers. This feature is required for some drivers but, if there are no - complaints, can be safely disabled. The worker thread also performs - garbage collection -- completing any delayed memory deallocations from - interrupt handlers. If the worker thread is disabled, then that clean up will - be performed by the IDLE thread instead (which runs at the lowest of priority - and may not be appropriate if memory reclamation is of high priority). - -config SCHED_WORKPRIORITY - int "Worker thread priority" - default 192 - depends on SCHED_WORKQUEUE - ---help--- - The execution priority of the worker thread.

Default: 192 - -config SCHED_LPWORKPERIOD - int "Lower priority worker thread period" - default 50000 - depends on SCHED_LPWORK - ---help--- - How often the lower priority worker thread checks for work in units - of microseconds.

If SCHED_HAVE_PARENT is also defined, then this - setting will modify the behavior or waitpid() (making more spec - compliant) and will enable the waitid() and wait() interfaces as - well. - -config SCHED_STARTHOOK - bool "Enable startup hook" - default n - ---help--- - Enable a non-standard, internal OS API call task_starthook(). - task_starthook() registers a function that will be called on task - startup before that actual task entry point is called.
