Upstream xtensa exception handling will save PS, PC, and a0 registers
together when saving a minimal context. This commit ppdates the xtensa
exception handling to match upstream behavior.
The following files were deleted:
- components/esp_hw_support/include/soc/cpu.h
- components/soc/esp32s3/include/soc/cpu.h
The following functions are deprecated:
- get_sp()
The following functions declared in soc/cpu.h are now moved to esp_cpu.h:
- esp_cpu_configure_region_protection()
The following functions declared in soc/cpu.h are now moved to components/xtensa/include/esp_cpu_utils.h:
- esp_cpu_process_stack_pc()
All files with soc/cpu.h inclusion are updated to include esp_cpu.h instead.

xPortStartScheduler calls vPortSetupTimer -> _frxt_tick_timer_init,
which enables tick timer interrupt and sets up the first timeout.
From that point on, the interrupt can fire. If the interrupt happens
while _frxt_dispatch is running, the scheduler will enter an infinite
loop. This is because _frxt_dispatch isn't supposed to be preemptable,
and the tick interrupt will overwrite some of the registers used by
_frxt_dispatch.
Note that this situation doesn't practically occur on the real
hardware, where the execution of vPortSetupTimer and _frxt_dispatch
happens quickly enough. However it can be reproduced on an emulator
if the tick period is set to 1ms.
Add an explicit call to portDISABLE_INTERRUPTS in xPortStartScheduler
to guarantee that _frxt_dispatch doesn't run with interrupts enabled.
This is similar to the esprv_intc_int_set_threshold(1); call in
RISC-V version of port.c.
This commit removes the portmacro.h include from task.h as portmacro.h
gets pulled in via FreeRTOS.h. This aligns with upstream FreeRTOS code.

This commit adds missing INCLUDE_ configurations to FreeRTOSConfig.h for
the following functions:
- xTaskAbortDelay()
- xTaskGetHandle()
Unit tests for these functions were also added.
Closes https://github.com/espressif/esp-idf/issues/7902
This issue was earlier fixed in commit 79e74e5d5f
but during migration to newer FreeRTOS release, it got introduced again.
This commit fixes thread safety issues with configASSERT() calls
regarding the value of uxSchedulerSuspended. A false negative
occurs if a context switch to the opposite core occurs in between
the getting the core ID and the assesment.

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.

The previous SMP freertos round robin would skip over tasks when
time slicing. This commit implements a Best Effort Round Robin
where selected tasks are put to the back of the list, thus
makes the time slicing more fair.
- Documentation has been updated accordingly.
- Tidy up vTaskSwitchContext() to match v10.4.3 more
- Increased esp_ipc task stack size to avoid overflow

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.

This commit removes the following critical nested macros as follows:
- portENTER_CRITICAL_NESTED()
- portEXIT_CRITICAL_NESTED()
They are replaced with portSET_INTERRUPT_MASK_FROM_ISR() and
portCLEAR_INTERRUPT_MASK_FROM_ISR() which are the proper FreeRTOS interfaces.
Created a portmacro_deprecated.h for each port to contain deprecated API
that were originally from portmacro.h
This commit adds the following hook functions to obtain memory
for the IDLE and Timer Daemon tasks when configSUPPORT_STATIC_ALLOCATION
is enabled:
- vApplicationGetIdleTaskMemory()
- vApplicationGetTimerTaskMemory()
Currently, both functions simply allocate from the same memory as
regular tasks (i.e., internal memory for both the stack and TCB)

Added DOC_EXCLUDE_SECTION section tag to conditionally remove sections
from FreeRTOS source files which we don't want in IDF API docs.
Added DOC_SINGLE_GROUP section tag to enable a flat document for
FreeRTOS and removing groups.
With these conditional tags, we can upstream FreeRTOS files without
affecting the upstream documentation.

components/os: Move ETS_T1_WDT_INUM, ETS_CACHEERR_INUM and ETS_DPORT_INUM to l5 interrupt
components/os: high level interrupt(5)
components/os: hli_api: meta queue: fix out of bounds access, check for overflow
components/os: hli: don't spill registers, instead save them to a separate region
Level 4 interrupt has a chance of preempting a window overflow or underflow exception.
Therefore it is not possible to use standard context save functions,
as the SP on entry to Level 4 interrupt may be invalid (e.g. in WindowUnderflow4).
Instead, mask window overflows and save the entire general purpose register file,
plus some of the special registers.
Then clear WindowStart, allowing the C handler to execute without spilling the old windows.
On exit from the interrupt handler, do everything in reverse.
components/bt: using high level interrupt in lc
components/os: Add DRAM_ATTR to avoid feature `Allow .bss segment placed in external memory`
components/bt: optimize code structure
components/os: Modify the BT assert process to adapt to coredump and HLI

* ##__VA_ARGS__ is replaced by __VA_OPT__(,)
and __VA_ARGS if C++20 is used.
* Affected header files are: esp_log.h,
portmacro.h and esp_check.h
* Closes https://github.com/espressif/esp-idf/pull/6692
portGET_ARGUMENT_COUNT uses a GCC extension ##__VA_ARGS__. It forces
the user to compile the code with GNU extensions enabled instead of ISO
language standard. The suggested change is to replace ##__VA_ARGS__ with
__VA_OPT__(,) __VA_ARGS__ which is supported by the current version of
GCC used in ESP-IDF for both C and C++ ISO standards.
This fix would enable ESP-IDF users to compile their code with ISO C++20
standard in future releases.

1. Add conditions based on Kconfig options for functions which are
compiled based on those options.
2. Static allocation is always enabled, move corresponding functions
into the common list.
Since dd849ffc, _rodata_start label has been moved to a different
linker output section from where the TLS templates (.tdata, .tbss)
are located. Since link-time addresses of thread-local variables are
calculated relative to the section start address, this resulted in
incorrect calculation of THREADPTR/$tp registers.
Fix by introducing new linker label, _flash_rodata_start, which points
to the .flash.rodata output section where TLS variables are located,
and use it when calculating THREADPTR/$tp.
Also remove the hardcoded rodata section alignment for Xtensa targets.
Alignment of rodata can be affected by the user application, which is
the issue dd849ffc was fixing. To accommodate any possible alignment,
save it in a linker label (_flash_rodata_align) and then use when
calculating THREADPTR. Note that this is not required on RISC-V, since
this target doesn't use TPOFF.
Noted as a problem with thread local storage returning a different task's
pointers, but some other were APIs also accessing current task unsafely.
Regression in FreeRTOS 10 update a3c90bf59a
Causes test added in parent commit to pass.
This race happens if the deleted task is running on the other CPU,
and is already spinning in a critical section waiting for xTaskQueueMutex
because it's about to be blocked for a resource.
The "deleted" task would end up blocked, possibly indefinitely, and
never actually deleted or its resources cleaned up by the idle tasks.
Details:
vTaskDelete() adds the target task to the xTasksWaitingTermination list,
expecting it to be yielded off CPU and then cleaned up later. However as soon as
vTaskDelete() releases xTaskQueueMutex, the target task runs and moves itself to the
xDelayedTaskList1. Because interrupts are already disabled on that CPU,
the "yield" to the other CPU sent by the vTaskDelete() comes afterward so
doesn't help.
Fixes issue with DPORT init task, this task uses minimum stack size and may not be
enough if stack smashing detection is set to Overall mode.
Also reworks the way we calculate minimum stack to allow for adding multiple
contributing factors.
Closes https://github.com/espressif/esp-idf/issues/6403
Unless the option for "assert and keep running" is enabled.
This means that silent asserts now work for FreeRTOS, and disabling asserts
now also disables them in FreeRTOS without needing a separate config change.

NOP instructions have been added in order to prevent the code
from executing code it shouldn't execute. This is due to a delay
between the moment an interrupt is requested and the moment it
is fired. It only happens on RISC-V SoC.
Enable shared stack watchpoint for overflow detection
Enable unit tests:
* "test printf using shared buffer stack" for C3
* "Test vTaskDelayUntil" for S2
* "UART can do poll()" for C3
Removed leftover code-paths that were never taken. Upstream freertos uses
vTaskSuspendAll() and xTaskResumeAll(), and therefor check if the task already
yielded.
In the IDF port of freertos we use critcal sections instead, so xAlreadyYielded
will never be set.
Partially addresses https://github.com/espressif/esp-idf/issues/6440
rtos_int_exit would store RA at an offset of 4 byte from the SP,
where the offset should be 0.
This caused rtos_int_exit to overwrite variables in bss.
The riscv vectors.S in riscv component contains the trap vector, which is responsible to
defer interrupts and examine if a task context switch is needed, this change cleans up
this code by hiding all freertos details behind on two functions rtos_it_enter/exit and
their implementations are placed in freertos riscv port files.
Add `xQueueGenericReceive` as that has been removed in FreeRTOS10.
This in turn breaks pre-builts libraries with earlier IDF releases
relying on this API.
