This commit optimizes xTaskRemoveFromEventList() by removing the
listLIST_IS_EMPTY() check from single core builds. The scenario of the event
list being empty when the function is called can only occur on multi-core
builds.
This commit fixes and optimizes vTaskRemoveFromUnorderedEventList() in the
following ways:
- Fixed bug in single core builds where the unblocked task would be placed on
xPendingReadyList.
- If an ISR occurs while accessing xPendingReadyList, and the ISR also
accesses the xPendingReadyList, xPendingReadyList would be corrupted.
- In single core builds, this function is only called from event groups with
the scheduler suspended. Thus the function should have exclusive access to
pxReadyTasksLists instead of xPendingReadyList.
- The function's single core logic has now been updated to match upstream
behavior, by always placing the unblocked task on pxReadyTasksLists.
- Optimized the function for single core builds by removing the
taskCAN_BE_SCHEDULED() check.
- In single core builds, given that the function is always called with the
scheduler suspended
- Thus, the taskCAN_BE_SCHEDULED (and the subsequent routine to place the
unblocked task on the xPendingReadyList) is not necessary for single core
builds.
- The function now matches upstream behavior in single core builds.

portBASE_TYPE is an internal macro defined by the porting layer. This commit
changes all references to BaseType_t which is the official type exposed by
FreeRTOS.
portSTACK_TYPE is an internal macro defined by the porting layer. This commit
changes all references to StackType_t which is the official type exposed by
FreeRTOS.
- add hardware stack guard based on assist-debug module
- enable hardware stack guard by default
- disable hardware stack guard for freertos ci.release test
- refactor rtos_int_enter/rtos_int_exit to change SP register inside them
- fix panic_reason.h header for RISC-V
- update docs to include information about the new feature
This commit adds a "CONFIG_FREERTOS_USE_KERNEL_10_5_1" hidden option to enable
building of the v10.5.1 kernel for development/testing purposes. Currently
enabling this option will just cause CMake to error out.
Also added a markdown file to record the code changes made to the V10.5.1 source
when porting over SMP behavior.
This commit adds the source files for the FreeRTOS Kernel V10.5.1 in
preparation for upgrading ESP-IDF FreeRTOS Kernel version (files copied from
https://github.com/FreeRTOS/FreeRTOS-Kernel/tree/V10.5.1)
The following modifications were made to the files when copying
- Added "SPDX-FileCopyrightText" and "SPDX-FileContributor" tags to all files
to pass ESP-IDF pre-commit checks.
- Left out some files unnecessary to ESP-IDF (e.g., URLs, "History.txt", and
"portable" folder).
freertos: Updated vTaskRemoveFromUnorderedEventList() to consider scheduler state before adding task to ready list
Closes IDF-5785
See merge request espressif/esp-idf!23482
vTaskRemoveFromUnorderedEventList() runs under the assumption that the
scheduler is suspended during the call. However, for IDF FreeRTOS, this
is not true. When dual-core system is active, this API call is made in
a critical section but without suspending the scheduler. This commit
updates the vTaskRemoveFromUnorderedEventList() function to now consider
the scheduler state on either cores before adding a task to the ready list.
This commit fixes a bug in xTaskRemoveFromEvenetList() where in the
check for scheduler suspension did not account for nested suspensions.
Additionally, this commit updates all checks for scheduler
suspension to follow a uniform way.
This commit refactors the "freertos" component's structure as follows:
- "FreeRTOSConfig.h" related files moved to "./config" directory
- Refactored CMakeLists.txt file in preparation for v10.5.1 upgrade
- Grouped list appends based on component organization
- Removed some unecessarily public "include_dirs"
- Removed FreeRTOS-openocd.c
- uxTopUsedPriority has been added back to tasks.c since v10.4.2
- Thus the workaround in FreeRTOS-openocd.c is no longer needed and can
be removed.
linux/lwip: Wrap some IO posix functions
* to workaourd the FreeRTOS EINTR issue (when building without lwip)
* to correctly choose the sub-system based on fd (when building with
lwip) -- passing control to either linux/system or to lwip
This commit also addapts tapio-if to provide DHCP client by default and
configurable settings for static IP
This commit refactors port_systick.c so that all ports (RISC-V vs Xtensa) of
all FreeRTOS implementations (IDF vs Amazon SMP FreeRTOS) use the same set of
tick interrupt functions. Thus, these funcitons are now common:
- vPortSetupTimer() to setup the tick interrupt's timer
- xPortSysTickHandler() that is called on each tick interrupt
* Added a POSIX/Linux simulator that is compatible with the Amazon
FreeRTOS SMP API. Note that the simulator itself is still
single core, like the IDF FreeRTOS POSIX/Linux simulator.
This commit adds the corresponding CreateWithCaps functions for tasks:
- xTaskCreatePinnedToCoreWithCaps()
- xTaskCreateWithCaps()
- vTaskDeleteWithCaps()
Documentation and migraiton guide have been updated accordingly.

This commit adds "bare metal stubs" xtensa_rtos.h glue layer to mimic a bare
metal OS port. The bare metal stubs don't access any components outside of the
G0 group.
The previous commit moved the OS agnostic files from the IDF FreeRTOS port to
the xtensa component, thus can be accessed by both IDF and Amazon SMP FreeRTOS.
This commit removes the redudant copies in the Amazon SMP FreeRTOS port.
When porting an RTOS to the Xtensa architecture, there are a few files that
are common to all Xtensa RTOS ports. These files form the Xtensa RTOS porting
layer (e.g., "xtensa_vectors.S", "xtensa_context.S"). An Xtensa RTOS port is
expected to provide an RTOS specific "xtensa_rtos.h" header to interface with
the Xtensa RTOS porting layer.
Previously, the Xtensa RTOS porting layer files were placed in the FreeRTOS
component. This commit does the following:
1. Moves the Xtensa RTOS porting layer files from the `freertos` component to
the `xtensa` component. The following files were moved:
- xtensa_asm_utils.h
- xtensa_context.S
- xtensa_loadstore_handler.S
- xtensa_vectors.S
2. Refactored xtensa component include paths to separate Xtensa RTOS porting
layer headers.
- Xtensa HAL headers included via `#include <xtensa/...h>`
- Xtensa RTOS porting layer headers included via `#include <...h>`
Note: The xtensa files in the Amazon SMP FreeRTOS port are not moved/deleted in
this commit to ensure the moved files retain a clean diff history.
When building for CONFIG_FREERTOS_SMP, "idf_additions.h" was previously
implicitly included by "task.h" so that other ESP-IDF components still have
access to IDF API additions without needing to include "idf_additions.h"
directly.
However, some FreeRTOS headers (e.g., queue.h) will include task.h before
declaring any types (e.g., QueueHandle_t). Thus if any of those types are used
in idf_additions.h, we get a missing type error.
This commit moves the implicity include of idf_additions.h to FreeRTOS.h
