This function moves ulTaskNotifyTake()/xTaskNotifyWait() from IDF FreeRTOS
`tasks.c` to `freertos_compatibility.c`. These functions were kept for
pre-compiled library compatibilty. Move them reduces the kernel source code
difference when compared to upstream FreeRTOS.
This commit combines various task utility API additions in IDF FreeRTOS and with
their Amazon SMP FreeRTOS addition counterparts. The folloiwng functions have
been moved to freertos_tasks_c_additions.h and idf_additions.h as these API
are considered public:
- xTaskGetCurrentTaskHandleForCPU()
- xTaskGetIdleTaskHandleForCPU()
- xTaskGetAffinity()
- pxTaskGetStackStart()
Also fixed in missing #if macros when vTaskCoreAffinityGet() is called in
Amazon SMP FreerTOS tests.
This commit moves xTaskIncrementTickOtherCores() to freertos_tasks_c_additions.h
and freertos_idf_additions_priv.h (as API is private). This reduces the code
differences cmpared to upstream FreeRTOS.
- The following IDF API additions are moved to freertos_tasks_c_additions.h
(implementation) and freertos_idf_additions_priv.h (declaration) as APIs are
private. This reduces the source code difference from upstream.
- prvENTER_CRITICAL_OR_SUSPEND_ALL()
- prvEXIT_CRITICAL_OR_RESUME_ALL()
- prvENTER_CRITICAL_OR_MASK_ISR()
- prvEXIT_CRITICAL_OR_UNMASK_ISR()
- vTaskTakeKernelLock()
- vTaskReleaseKernelLock()
- Rename vTask[Take/Release]KernelLock() to prv[Take/Release]KernelLock() to
indicate that the this API is private.
- Move vTaskStartSchedulerOtherCores()
- implementation to freertos_tasks_c_additions.h
- declaration to freertos_idf_additions_priv.h as API is private
- Rename vTaskStartSchedulerOtherCores() -> prvStartSchedulerOtherCores() to
indicate that the function is private.
This commit adds an implicit inclusion of `idf_additions.h` to `FreeRTOS.h` in
preparation for moving some IDf specific API to `idf_additions.h`.
This implict inclusion allows existing code to be continue using these
relocated APIs without any changes in header inclusions.
Also removed "#pragma once" directive from "freertos_tasks_c_additions.h" since
that header is included as a source file.
For certain data lengths, the last input descriptor was not getting appended
correctly and hence the EOF flag in the DMA descriptor link list was
set at incorrect location. This was resulting in the peripheral being
stalled expecting more data and eventually the code used to timeout
waiting for the AES completion interrupt.
Required configs for this issue:
CONFIG_MBEDTLS_HARDWARE_AES
CONFIG_SOC_AES_SUPPORT_DMA
This observation is similar to the issue reported in:
https://github.com/espressif/esp-idf/issues/10647
To recreate this issue, start the AES-GCM DMA operation with data length
12280 bytes and this should stall the operation forever.
In this fix, we are tracing the entire descriptor list and then appending the
extra bytes descriptor at correct position (as the last node).
DMA operation completion must wait until the last DMA descriptor
ownership has been changed to hardware, that is hardware is completed
the write operation for entire data. Earlier for the hardware GCM case,
the first DMA descriptor was checked and it could have resulted in some
race condition for non interrupt (MBEDTLS_AES_USE_INTERRUPT disabled) case.
