+
+ If the is less than the task storage area size, then the task construction
+ by :ref:`InterfaceRtemsTaskConstruct` fails.
+
+ The actual thread-local storage size is determined when the application

+Task switch extensions are invoked when a thread switch from an executing
+thread to a heir thread takes place.
+
+.. rubric:: NOTES:
+
+The task switch extensions are invoked in :term:`extension forward order`.
+
+The invocation conditions of the task switch extensions depend on whether RTEMS
+was built with SMP support enabled or disabled. A user must pay attention to
+the differences to correctly implement a task switch extension.
+
+Where the system was built with SMP support disabled, the task switch
+extensions are invoked before the context switch from the currently executing
+thread to the heir thread. The executing is a pointer to the :term:`TCB` of
+the currently executing thread. The heir is a pointer to the TCB of the heir
+thread. The context switch initiated through the multitasking start is not
+covered by the task switch extensions.
+
+Where the system was built with SMP support enabled, the task switch extensions
+are invoked after the context switch to the heir thread. The executing is a
+pointer to the TCB of the previously executing thread. Despite the name, this
+is not the currently executing thread. The heir is a pointer to the TCB of the
+newly executing thread. This is the currently executing thread. The context
+switches initiated through the multitasking start are covered by the task
+switch extensions. The reason for the differences to uniprocessor
+configurations is that the context switch may update the heir thread of the
+processor. The task switch extensions are invoked with maskable interrupts
+disabled and with ownership of a processor-specific SMP lock. Task switch
+extensions may run in parallel on multiple processors. It is recommended to
+use thread-local or processor-specific data structures for task switch
+extensions. A global SMP lock should be avoided for performance reasons, see
+:ref:`InterfaceRtemsInterruptLockInitialize`.
