 - ### Locking discipline and lock invariants
- FreeRTOS' SMP implementation uses the following synchronization mechanisms:
-    - Deactivating interrupts:
-
-   Some data is only meant to be accessed on a specific core C.
-   Such data may only be accessed after interrupts on core C have been deactivated.
-   For instance the global array `pxCurrentTCBs` in `tasks.c` has an entry for
-   every core.
-   `pxCurrentTCBs[C]` stores a pointer to the task control block (TCB) of the task running on core C.
-   Core C is always allowed to read `pxCurrentTCBs[C]`.
-   However, writing requires the interrupts on core C to be deactivated.

    The task lock is used to protect ciritical sections and resources from being accessed by multiple tasks simultaneously.
