The select function wrapper was rewritten to be non-blocking
on Linux systems, as it was stealing all the CPU time
from lower priority tasks when called from a higher priority task.
This is because the FreeRTOS scheduler does not know
that the task thread is sleeping during the system call.
This issue manifests all "slow" system calls on the Linux target,
but handling the case of select fixes the problems for most ESP-IDF components.
The FreeRTOS POSIX port documentation lists this as a known issue,
so user code is responsible handling this case if other system calls are used,
even if unknowingly.
This closes GH issue #14395 "select() blocks the FreeRTOS scheduler on Linux target"
feat(newlib): add option to disable eval of expression in assert() when NDEBUG set
Closes IDFGH-479 and IDFGH-8692

The vTaskPlaceOnEventListRestricted() did not use the correct macro when
exiting a kernel cirtical section. This does not affect the HW targets
but on the Linux port, this caused an issue as the critical nesting
count became negative, leading to deadlocks. This commit fixes the bug
and updates the linux port to prevent the nesting count from going
negative.
This commit fixes an issue where in the FreeRTOS port layer would cause
the portASSERT_IF_IN_ISR() assert check to fail even when the system is
not in an interrupt context.
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.

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.
