| * Modifications to portENTER_CRITICAL. |
| * |
| * For an introduction, see "Critical Sections & Disabling Interrupts" in docs/api-guides/freertos-smp.rst |
| * |
| * The original portENTER_CRITICAL only disabled the ISRs. This is enough for single-CPU operation: by |
| * disabling the interrupts, there is no task switch so no other tasks can meddle in the data, and because |
| * interrupts are disabled, ISRs can't corrupt data structures either. |
| * |
| * For multiprocessing, things get a bit more hairy. First of all, disabling the interrupts doesn't stop |
| * the tasks or ISRs on the other processors meddling with our CPU. For tasks, this is solved by adding |
| * a spinlock to the portENTER_CRITICAL macro. A task running on the other CPU accessing the same data will |
| * spinlock in the portENTER_CRITICAL code until the first CPU is done. |
| * |
| * For ISRs, we now also need muxes: while portENTER_CRITICAL disabling interrupts will stop ISRs on the same |
| * CPU from meddling with the data, it does not stop interrupts on the other cores from interfering with the |
| * data. For this, we also use a spinlock in the routines called by the ISR, but these spinlocks |
| * do not disable the interrupts (because they already are). |
| * |
| * This all assumes that interrupts are either entirely disabled or enabled. Interrupt priority levels |
| * will break this scheme. |
| * |
| * Remark: For the ESP32, portENTER_CRITICAL and portENTER_CRITICAL_ISR both alias vTaskEnterCritical, meaning |
| * that either function can be called both from ISR as well as task context. This is not standard FreeRTOS |
| * behaviour; please keep this in mind if you need any compatibility with other FreeRTOS implementations. |
