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.
Closes https://github.com/espressif/esp-idf/issues/7137
Previously, Task Snapshot could be conditionally built based on the
CONFIG_FREERTOS_ENABLE_TASK_SNAPSHOT option. However, there is no overhead
with always enabling Task Snapshot functions, as the linker will remove any
functions if they are not called.
This commit...
- removes all ESP-IDF dependencies on the CONFIG_FREERTOS_ENABLE_TASK_SNAPSHOT
option so that Task Snapshot functions are always available.
- Makes CONFIG_FREERTOS_ENABLE_TASK_SNAPSHOT a hidden option to maintain
compatibility with user code.
- adds documentation regarding Task Snapshot.
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.
* 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 "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.
This commit merges the "FreeRTOSConfig_smp.h" file into the "FreeRTOSConfig.h".
The configurations for all FreeRTOS implementations are now stored in a single
file.
Since core affinity is supported in task stats by default in Amazon
FreeRTOS SMP, the Kconfig option
CONFIG_FREERTOS_VTASKLIST_INCLUDE_COREID is now made only available for
IDF-FreeRTOS.
An explicit check of the mutex owner during a mutex release operation is
not necessary for FreeRTOS SMP as this is checked by default. Hence, the
corresponding Kconfig option is removed.
* 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
For RISC-V and Xtensa targets, in case a panic needs to happen when
Task WDT is triggered (ESP_TASK_WDT_PANIC), the interruptee's stack
is now used for printing the backtrace.
Abort after Task Watchdog is triggered can happen on APP CPU (second core).
The TLSP deletion callback feature is not compatible with the CONFIG_FREERTOS_ENABLE_STATIC_TASK_CLEAN_UP
option. However, the "freertos_options" unit test configuration will enable that option.
This commit disables all CONFIG_FREERTOS_ENABLE_STATIC_TASK_CLEAN_UP related features when compiling with
SMP FreeRTOS.
This commit refactors FreeRTOS Kconfig options as follows:
- Grouped them into Kernel and Port submenus
- Renamed Kernel option promppts to match upstream names
- Simplified some option descriptions
- Added "Todo" markers related to SMP support
This commit updates how the TLS pointers deletion callbacks are called
during task deletion in the FreeRTOS SMP kernel. The callbacks are now
routed through the portCLEAN_UP_TCB() macro. This commit also adds a
new kconfig option CONFIG_FREERTOS_TLSP_DELETION_CALLBACKS to control
the enablement of the TLSP deletion callbacks.
Moved the following kconfig options out of the target component:
* CONFIG_ESP*_DEFAULT_CPU_FREQ* -> esp_system
* ESP*_REV_MIN -> esp_hw_support
* ESP*_TIME_SYSCALL -> newlib
* ESP*_RTC_* -> esp_hw_support
Where applicable these target specific konfig names were merged into
a single common config, e.g;
CONFIG_ESP*_DEFAULT_CPU_FREQ -> CONFIG_ESP_DEFAULT_CPU_FREQ_MHZ
This commit updates the usage of idle hooks in SMP FreeRTOS as follows:
- IDF style idle hooks are now called from vApplicationMinimalIdleHook()
- If the user provdies their own vApplicationMinimalIdleHook(), it can be
wrapped using -Wl,--wrap if CONFIG_FREERTOS_USE_MINIMAL_IDLE_HOOK is
enabled.
- SMP port no longer uses vApplicationIdleHook() as it's only called from
the prvIdleTask() and not every prvMinimalIdleTask()
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.
Moved the following kconfig options out of the target component:
* ESP32_X_BROWNOUT_* -> esp_system
* ESP32_X_DEBUG_OCDAWARE -> esp_system
* APP_NO_BLOBS -> build type (main kconfig)
This commit removes the usage of all legacy FreeRTOS data types that
are exposed via configENABLE_BACKWARD_COMPATIBILITY. Legacy types can
still be used by enabling CONFIG_FREERTOS_ENABLE_BACKWARD_COMPATIBILITY.
