In IDF FreeRTOS, when building for SMP, there are numerous functions
which require different critical sections when compared to single-core. This
commit encapsulates those difference into a common set of macros whose
behavior depends on "configNUM_CORES > 1". As such...
- Vanilla behavior has been restored for some functions when building for
single core (i.e., used to call taskENTER_CRITICAL, now disables interrupts
mactching vanilla behavior).
- Reduces number of "#ifdef (configNUM_CORES > 1)" in functions
- Any SMP only critical sections are now wrapped by
"#ifdef (configNUM_CORES > 1)" and properly documented via comments.
This commit synchronize the cosmetic differences of IDF FreeRTOS to upstream
Vanilla v10.4.3. Comsetic differences include:
- Out of date doxygen API descriptions
- Misnamed parameters
- Missing examples
- Fixed/added missing @cond/@code directives
- Extra/missing comments/lines
- Code formatting (uncrustify)
Other changes:
- Some ESP_PLATFORM directives were also removed
- xTaskIncrementTickOtherCores() now depends on "configNUM_CORES > 1"
- Updated some multi-core dummy variable names in FreeRTOS.h
This commit refactors the way stream buffers initialize their spinlock.
- "prvInitialiseNewStreamBuffer()" now initializes the stream buffer fields
manually (instead of using memset()) to avoid resetting the spin lock
- Stream buffer creation functions now manually initialize the spinlock after
the other fields are initialized using "prvInitialiseNewStreamBuffer()"
Also added comments to event group spinlock initializtion.
This commit reverts the previous "taskENTER_CRTIICAL();" so that the argument
is now provided for better code readability. The names of the spinlocks have
also been updated.
This commit does the following:
- Adds SPDX license identifiers to FreeRTOS sources. Remove those FreeRTOS sources from
the copyright ignore list.
- Update xtensa port files to match FreeRTOS v10.4.3. Added SPDX license identifiers
to the port files.
- Fixed some improperly licensed files
- Removed portbenchmark.h from RISC-V port
Add TRY_ENTRY_CRITICAL() API to all for timeouts when entering critical sections.
The following port API were added:
- portTRY_ENTER_CRITICAL()
- portTRY_ENTER_CRITICAL_ISR()
- portTRY_ENTER_CRITICAL_SAFE()
Deprecated legacy spinlock API in favor of spinlock.h. The following API were deprecated:
- vPortCPUInitializeMutex()
- vPortCPUAcquireMutex()
- vPortCPUAcquireMutexTimeout()
- vPortCPUReleaseMutex()
Other Changes:
- Added portMUX_INITIALIZE() to replace vPortCPUInitializeMutex()
- The assembly of the critical section functions ends up being about 50 instructions longer,
thus the spinlock test pass threshold had to be increased to account for the extra runtime.
Closes https://github.com/espressif/esp-idf/issues/5301
This function resets the spinlock given as a parameter after taking it
(when entering the critical section). This then results in a panic once
it tries to exit the same critical section.
* Closes https://github.com/espressif/esp-idf/issues/7725
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.
