This commit mainly targets the ESP32-P4. It adds supports for coprocessors on
RISC-V based targets. The coprocessor save area, describing the used coprocessors
is stored at the end of the stack of each task (highest address) whereas each
coprocessor save area is allocated at the beginning of the task (lowest address).
The context of each coprocessor is saved lazily, by the task that want to use it.
change(freertos): Upgrade ESP-IDF to use FreeRTOS v10.5.1, remove v10.4.3
Closes IDF-8191, IDF-8200, IDF-8201, IDF-8363, and IDF-8364
See merge request espressif/esp-idf!26261
This commit does the following:
- Update doxygen comments in FreeRTOS headers to remove unsupported doxygen
labels and internal functions
- Fixed existing doxygen warnings in FreeRTOS headers
This commit temporarily disables a bugfixed introduced by FreeRTOS v10.5.1 that
ensures timed out tasks will only preempt if their priority is higher than the
currently running task.
This bugfix has been temporarily reversed due to some compatibility issues with
some IDF tests.
This commit adds a workaround for a compiler optimization issue in FreeRTOS
v10.5.1 in xTaskResumeAll() where pxTCB is only read once, even if in a loop.
A follow up ticket has been added to properly resolve this issue.
This commit optimizes the following utility functions to achieve higher
overall system performance:
xTaskGetCurrentTaskHandle():
- Made into stand alone function instead of wrapper call to "ForCore" variant
- Replaced critical sections with disabling interrupts. Lack of lock contention
improves performance.
xTaskGetCurrentTaskHandleForCore():
- Removed unecessary critical sections
xTaskGetSchedulerState():
- Replaced critical sections with disabling interrupts. Lack of lock contention
improves performance.
Previously the linux port of FreeRTOS set configMAX_PRIORITIES to 7. However,
multiple linux POSIX simulator examples will call API that create tasks with
priortiies >= 7.
This commit fixes the configMAX_PRIORITIES and unifies all ports to have 25
priorities.
This commit fixes the FreeRTOS CMock component in the following ways:
- Updated include directories to work with vanilla FreeRTOS v10.5.1
`#include "portmacro.h"` style inclusion.
This commit updates the sdkconfig for some examples when building with the
v10.5.1 kernel. The updates fixes the following:
Place FreeRTOS functions into flash
- Some examples use nearly 100% of available IRAM, thus any small increase in
IRAM in other components (e.g., FreeRTOS) will lead to a build error. As a
result, 'CONFIG_FREERTOS_PLACE_FUNCTIONS_INTO_FLASH' has been enabled in those
examples to save some IRAM.
- Some examples consume too much flash memory, leading to the 'factory'
parition overflowing. IN those examples,
'CONFIG_PARTITION_TABLE_SINGLE_APP_LARGE' has been enabled to use a larger
'factory' partition.
Various convenience macros in tasks.c will simply leave macro arguments unused
when built for single-core. This leads to an 'unused variable' warning.
This commit updates those macrso so that the unused arguments have a
'(void)' statement.
