/* This header exists for performance reasons, in order to inline the
|
|
* implementation of vPortCPUAcquireMutexIntsDisabled and
|
|
* vPortCPUReleaseMutexIntsDisabled into the
|
|
* vTaskEnterCritical/vTaskExitCritical functions in task.c as well as the
|
|
* vPortCPUAcquireMutex/vPortCPUReleaseMutex implementations.
|
|
*
|
|
* Normally this kind of performance hack is over the top, but
|
|
* vTaskEnterCritical/vTaskExitCritical is called a great
|
|
* deal by FreeRTOS internals.
|
|
*
|
|
* It should be #included by freertos port.c or tasks.c, in esp-idf.
|
|
*
|
|
* The way it works is that it essentially uses portmux_impl.inc.h as a
|
|
* generator template of sorts. When no external memory is used, this
|
|
* template is only used to generate the vPortCPUAcquireMutexIntsDisabledInternal
|
|
* and vPortCPUReleaseMutexIntsDisabledInternal functions, which use S32C1 to
|
|
* do an atomic compare & swap. When external memory is used the functions
|
|
* vPortCPUAcquireMutexIntsDisabledExtram and vPortCPUReleaseMutexIntsDisabledExtram
|
|
* are also generated, which use uxPortCompareSetExtram to fake the S32C1 instruction.
|
|
* The wrapper functions vPortCPUAcquireMutexIntsDisabled and
|
|
* vPortCPUReleaseMutexIntsDisabled will then use the appropriate function to do the
|
|
* actual lock/unlock.
