This commit changes the approach used to override select function
in FreeRTOS simulator.
The previous approach relied on '--wrap', which is a feature of GNU
linker that performs symbol substitution at link time. Sadly this
feature is not present in macOS linker.
The alternative solution is to define 'select' wrapper as a regular
(exported) symbol, preventing it from being loaded from system
libraries. To call the "real" select implementation we use dlsym
function and find the function pointer at run time. This solution
works on both Linux and macOS.
This commit makes v10.5.1 the default FreeRTOS kernel in ESP-IDF by removing
the CONFIG_FREERTOS_USE_KERNEL_10_5_1 option and v10.4.3 specific code
blocks.
This commit adds beta support for the FreeRTOS v10.5.1 kernel which can be
enabled by enabling the CONFIG_FREERTOS_USE_KERNEL_10_5_1 option.
The following changes have been made:
- Updated freertos/CMakeLists.txt to build v10.5.1 kernel with v10.4.3. ports
- Updated existing Xtensa and RISC-V ports to work with V10.5.1
- Modifications to other ESP-IDF components to work with v10.5.1
- Added some ESP-IDF specific tracing changes to v10.5.1 kernel
- Make CONFIG_FREERTOS_USE_KERNEL_10_5_1 a public option
Note: The beta release is missing some minor fixes, performance improvements,
and features. Using this beta release for production is not recommended.

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.
Previously, if CONFIG_FREERTOS_ENABLE_STATIC_TASK_CLEAN_UP was enabled, users
would provide a definition for a vPortCleanUpTCB() hook function that is called
right before a task's memory is freed in prvDeleteTCB(). However,
vPortCleanUpTCB() will be reclaimed by ESP-IDF for internal use in v6.0.
This commit introduces the following changes...
Introduced a new CONFIG_FREERTOS_TASK_PRE_DELETION_HOOK option:
- Provides the same pre-deletion hook functionality. But users now define
vTaskPreDeletionHook() instead.
- CONFIG_FREERTOS_ENABLE_STATIC_TASK_CLEAN_UP still exists, but is marked as
deprecated. This is to maintain compatibility with existing applications
that already define vPortCleanUpTCB().
- Removed redundant --wl --wrap workaround with vPortCleanUpTCB()
- Added todo notes to remove support for user defined vPortCleanUpTCB()
completely in v6.0.
- Updated test cases to use new CONFIG_FREERTOS_TASK_PRE_DELETION_HOOK option
Freed up portCLEAN_UP_TCB() to call a new internal vPortTCBPreDeleteHook():
- vPortTCBPreDeleteHook() now replaces the previous "wrapped" implementation
of vPortCleanUpTCB().
- vPortTCBPreDeleteHook() is an internal task pre-delete hook for IDF FreeRTOS
ports to inject some pre-deletion operations.
- Internal pre-delete hook now invokes user provided vTaskPreDeletionHook()
if enabled.
- Relocated vPortTCBPreDeleteHook() to correct section in port.c
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 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
* 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.
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.
Previously, some IDF FreeRTOS API additions that were meant to be private were
exposed through the same "idf_additions.h" header. This commit moves those
functions to a separate header included via
"esp_private/freertos_idf_additions_priv.h" so that they are not mistaken as
public API by users.
This commit also fixes some missing include and C++ guards in idf_additions.h
freertos_tasks_c_additions.h is technically included as source file. This
commit removes the "private_include" directory of "freertos_tasks_c_additions.h"
and treats it as a source file of "esp_additions".
The default implementation of some xtensa vectors were previously moved to
"xtensa_vector_defaults.S" as weak functions so that they could be overriden.
This commit moves these default vectors back into "xtensa_vectors.S" in
preparation for further refactoring of the xtensa component.
Vanilla FreeRTOS expects applications to use one of the heap implementations
provided by FreeRTOS (i.e., heap_x.c), where functions such as pvPortMalloc()
and vPortFree() are defined in the heap implementation.
However, ESP-IDF already provides its own heap implementation
(i.e., esp_heap_caps.h). Thus, the pvPortMallc()/vPortFree() functions were
previously overriden by macro to call esp_heap functions directly.
This commit refactors the FreeRTOS port's heap as such:
- Added a heap_idf.c that implements all of the heap related functions required
by FreeRTOS source
- All dynamic memory allocated by FreeRTOS is from internal memory. Thus, the
FreeRTOS heap is the internal memory subset of the ESP-IDF heap.
- Removed some old macros to reduce diff from upstream source code.
This commit adds a separate linker fragment file "linker_common.lf" for the
functions in "port_common.c". The placement rules are now clearly specified
inside the linker fragment file.
This commit refactors port_common.c so that it only contains implementation of
FreeRTOS port functions that are common to all FreeRTOS ports (i.e., on all
architectures and on all FreeRTOS implementations).
This commit refactors the OS startup functions as follows:
- Moved the OS/app startup functions listed below to "app_startup.c". Their
implementations are now common to all ports (RISC-V and Xtensa) of all
FreeRTOS implementations (IDF and Amazon SMP).
- esp_startup_start_app()
- esp_startup_start_app_other_cores()
- Removed esp_startup_start_app_common() as app startup functions are now
already common to all ports.
- Added extra logs to "main_task" to help with user debugging
Note: Increased startup delay on "unity_task". The "unity_run_menu()" is non
blocking, thus if the main task or other startup tasks have not been freed
by the time "unity_run_menu()" is run, those tasks will be freed the next time
"unity_task" blocks. This could cause some tests to have a memory leak, thus
the "unity_task" startup delay has increased.
* Added port layer from the FreeRTOS POSIX port, added
additional port code for ESP-IDF.
* Created another hello world example using that POSIX
port in tools/test_apps.
* Removed old linux app
The CONFIG_FREERTOS_PLACE_FUNCTIONS_INTO_FLASH allows some FreeRTOS functions to be placed
into flash, thus saving some IRAM. However, this feature was previously not supported for
SMP FreeRTOS.
This commit adds CONFIG_FREERTOS_PLACE_FUNCTIONS_INTO_FLASH support for SMP FreeRTOS. There
are now separate linker fragment files for IDF FreeRTOS and SMP FreeRTOS, named "linker.lf"
and "linker_smp.lf" respectively.
esp_timer will be added as a dependency to freertos only if
CONFIG_FREERTOS_RUN_TIME_STATS_USING_ESP_TIMER is enabled.
Other components are updated to add esp_timer as public or private
dependency, as needed.
This removes esp_timer from the default list of public dependencies.
This commit updates task snapshot as follows:
- Refactored implementation to increase readability
- Implementation moved into freertos_tasks_c_additions.h
- freertos_tasks_c_additions.h made a private header
- Support SMP FreeRTOS
- Removed configENABLE_TASK_SNAPSHOT option. CONFIG_FREERTOS_ENABLE_TASK_SNAPSHOT
is direclty used instead.
This commit does the following:
- Add a Kconfig option to select between the IDF FreeRTOS kernel and the
FreeRTOS SMP kernel.
- Updates the freertos component's CMakeLists.txt so that FreeRTOS SMP
files are now built based the the new configuration option.
This commit WILL NOT compile. The port files for FreeRTOS SMP still need to
be updated.
The following changes have been made:
1. All FreeRTOS kernel source files are now placed in the
freertos/FreeRTOS-Kernel folder to match with the upstream folder structure.
2. All kernel include files are now placed in freertos/FreeRTOS-Kernel/include.
3. All port files are now placed in freertos/FreeRTOS-Kernel/portable.
4. All additions/customizations are placed in freertos/esp_additions.
5. All other miscellaneous files (README, License files etc.) are moved to
freertos/FreeRTOS-Kernel folder to match with the upstream.
6. Updated esp-cryptoauthlib to latest commit to resolve FreeRTOS
include dependencies.

Add `xQueueGenericReceive` as that has been removed in FreeRTOS10.
This in turn breaks pre-builts libraries with earlier IDF releases
relying on this API.
