/* 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.
