* @brief Udebug hooks and data structure management. |
* |
* Udebug is an interface that makes userspace debuggers possible. |
* |
* Functions in this file are executed directly in each thread, which |
* may or may not be the subject of debugging. The udebug_stoppable_begin/end() |
* functions are also executed in the clock interrupt handler. To avoid |
* deadlock, functions in this file are protected from the interrupt |
* by locking the recursive lock THREAD->udebug.int_lock (just an atomic |
* variable). This prevents udebug_stoppable_begin/end() from being |
* executed in the interrupt handler (they are skipped). |
* |
* Functions in udebug_ops.c and udebug_ipc.c execute in different threads, |
* so they needn't be protected from the (preemptible) interrupt-initiated |
* code. |
