This commit updates the source files of Amazon SMP FreeRTOS to upstream
V11.1.0 (https://github.com/FreeRTOS/FreeRTOS-Kernel/tree/V11.1.0).
This version contains some new features and bugfixes. See upstream V11.1.0
release notes for more details.
Note: ESP-IDF specific changes to the source file have been preserved
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.
vTaskSuspendAll() requires critical sections when building for SMP. Otherwise,
it is possible for a task to switch cores in between getting the core ID and
before incremented uxSchedulerSuspended.
xCoreID was previously printed as the last parameter priority to IDF v5.1, but
was changed to the third paramtere from v5.2 onwards. This commit restores the
correct ordering.
Closes https://github.com/espressif/esp-idf/issues/13675
This commit fixes a bug where the portTRY_ENTER_CRITICAL_SAFE() for the
Xtensa and RISC-V FreeRTOS ports were broken as it did not correctly use
the timeout parameter.

This commit fixes a potential issue of illegal memory access when
accessing the various task lists in FreeRTOS while fetching tasks using
the xTaskGetNext() function.
- move .tbss to NOLOAD section
- remove xtensa-specific entities from riscv scripts
- explicit eh_frame terminator instead of "align magic"
- 80 characters line length limit
- refactor comments
- discard .rela sections (the rela data will go to relates sections)
This commit updates the dependency for
CONFIG_FREERTOS_TASK_FUNCTION_WRAPPER to be dependent explicitly on
CONFIG_ESP_SYSTEM_PANIC_GDBSTUB or CONFIG_ESP_SYSTEM_GDBSTUB_RUNTIME
instead of CONFIG_ESP_GDBSTUB_ENABLED which caused FreeRTOS Task
Function Wrappers to be enabled even if the esp_gdbstub component was
part of the build.
- 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
fix(riscv): Updated RISC-V functions to set interrupt threshold for CLIC targets
Closes IDFCI-2033, IDFCI-2034, IDF-8090, and IDF-8117
See merge request espressif/esp-idf!29055
This commit introduce SOC_MEM_NON_CONTIGUOUS_SRAM flag (that enebled for
esp32p4). If SOC_MEM_NON_CONTIGUOUS_SRAM is enabled:
- LDFLAGS+=--enable-non-contiguous-regions
- ldgen.py replaces "arrays[*]" from sections.ld.in with objects under
SURROUND keyword. (e.g. from linker.lf: data -> dram0_data SURROUND(foo))
- "mapping[*]" - refers to all other data
If SOC_MEM_NON_CONTIGUOUS_SRAM, sections.ld.in file should contain at
least one block of code like this (otherwise it does not make sense):
.dram0.bss (NOLOAD) :
{
arrays[dram0_bss]
mapping[dram0_bss]
} > sram_low
.dram1.bss (NOLOAD) :
{
/* do not place here arrays[dram0_bss] because it may be splited
* between segments */
mapping[dram0_bss]
} > sram_high
This commit added the RISC-V utility functions to set the interrupt
threshold for CLIC targets by using direct register value writes.
This makes the functions more efficient during run-time.
This is done to improve the critical section enter and exit performance on esp32p4.
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.

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.
