FreeRTOS tasks may now freely use the PIE coprocessor and HWLP feature.
Just like the FPU, usiing these coprocessors result in the task being pinned
to the core it is currently running on.
- vTaskPreemptionDisable()/vTaskPreemptionEnable() are no longer available in
single-core builds.
- xTaskIncrementTick() calls must now be wrapped by critical section
- Minimal Idle Task renamed to Passive Idle Task
- Port critical section APIs updated
This commit replaces the use of portNUM_PROCESSORS and configNUM_CORES
macros in all of ESP-IDF. These macros are needed to realize an SMP
scenario by fetching the number of active cores FreeRTOS is running on.
Instead, a new Kconfig option, CONFIG_FREERTOS_NUMBER_OF_CORES, has been
added as a proxy for the FreeRTOS config option, configNUMBER_OF_CORES.
This new commit is now used to realize an SMP scenario in various places
in ESP-IDF.
[Sudeep Mohanty: Added new Kconfig option CONFIG_FREERTOS_NUMBER_OF_CORES]
Signed-off-by: Sudeep Mohanty <sudeep.mohanty@espressif.com>
IDF FreeRTOS v10.5.1 no longer accepts out of range xCoreID arguments in
"PinnedToCore" task creation functions when building for single-core. This
commit fixes those violations through ESP-IDF.
This commit deprecates the "freertos/xtensa_api.h" and "xtensa/xtensa_api.h"
include paths. Users should use "xtensa_api.h" instead.
- Replace legacy include paths
- Removed some unnecessary includes of "xtensa_api.h"
- Replaced some calls with "esp_cpu_..." equivalents
- Add warning to compatibility header
This commit refactors suspend-resume tests by moving them to appropraite
test files. This commit also removes tests which are not necessary or
have been subsumed by refactored tests.
This commit adds the ability to set the core affinity for the FreeRTOS
Timer Service task when multi-core configuration is enabled. This commit
also adds a Kconfig option to set the core affinity of the timer task
via the menuconfig.
Closes https://github.com/espressif/esp-idf/issues/10315
This commit deprecates xTaskGetAffinity(), xTaskGetCurrentTaskHandleForCPU()
and xTaskGetIdleTaskHandleForCPU() APIs for IDF-FreeRTOS kernel.
Instead, users are directed to use alternatives. All other
components in IDF using these functions have been updated accordingly.
* Added prvTaskCreateDynamicAffinitySetWithCaps
and prvTaskCreateDynamicPinnedToCoreWithCaps
which allocate the task's stack in PSRAM instead of
internal RAM. These functions are only available if
PSRAM is enabled.
Task snapshot API were never intended to be called from user code. This commit
makes task snapshot a private API thus moves `#include "freertos/task_snapshot.h"`
to `#include "esp_private/freertos_debug.h"`.
Task snapshot related Kconfig options have also been hidden.
Note: Added 'freertos_common' mapping to ldgen mapping execptions lists due to
inlining of 'freertos_debug.h' functions.
Some component test apps do not use the "set(COMPONENTS main)" command in their
project level "CMakeLists.txt", thus leading to their builds pulling in all
ESP-IDF components.
This commit trims the build of multiple component test apps:
- Add "set(COMPONENTS main ...)" to project level "CMakeLists.txt"
- Add missing "PRIV_REQUIRES" in some "main" component "CMakeLists.txt"
Also removed repeated configuraiton options in legacy_i2c_driver/sdkconfig.ci.defaults
as they are already specified in legacy_i2c_driver/sdkconfig.defaults
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.
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, TLSP deletion callbacks were...
- Stored in a seprate TCB member "pvThreadLocalStoragePointersDelCallback"
- Called separately via multipole prvDeleteTLS() insertions in tasks.c
This commit refactors how TLSP deletion callbacks are stored and called:
- TLSP deletion callbacks are now stored in "pvThreadLocalStoragePointers"
directly. configNUM_THREAD_LOCAL_STORAGE_POINTERS is doubled in size so that
the deletion callbacks are stored in the latter half of the array
- The callbacks are now called via "portCLEAN_UP_TCB()". As such, the
prvDeleteTLS() additions are no longer needed and the function can be removed
- Removed some legacy TLSP tests using the old method of storing the callback
pointers.
This commit reduces the source code diff between IDF FreeRTOS and upstream
vanilla FreeRTOS, in preparation for v10.5.1 upgrade.
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
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.
- 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
