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.
- add hardware stack guard based on assist-debug module
- enable hardware stack guard by default
- disable hardware stack guard for freertos ci.release test
- refactor rtos_int_enter/rtos_int_exit to change SP register inside them
- fix panic_reason.h header for RISC-V
- update docs to include information about the new feature
The race condition is very unlikely on real hardware but can be observed with
qemu under heavy load.
Also add missing `memw` instructions which are generated by the C compiler but
absent in the assembly code.

Closes https://github.com/espressif/esp-idf/issues/11433
Memprot functions are no longer placed by default in IRAM,
selecting ESP_PANIC_HANDLER_IRAM will still force panic related memprot
functions to be placed in IRAM.
esp_execute_shared_stack_function always restored the stack watchpoint
regardless of CONFIG_FREERTOS_WATCHPOINT_END_OF_STACK. This would lead
to an abondoned but active watchpoint on a former stack once the task
calling esp_execute_shared_stack_function is deleted, if
CONFIG_FREERTOS_WATCHPOINT_END_OF_STACK is inactive.
This has been fixed now.
Closes https://github.com/espressif/esp-idf/issues/10414
ESP32-C2 has a single group timer, thus it will use it for the interrupt watchdog,
which is more critical than the task watchdog. The latter is implement in
software thanks to the `esp_timer`component.
- Remove esp_cpu_in_ocd_mode() from esp_cpu.h. Users should call esp_cpu_dbgr_is_attached() instead.
- Remove esp_cpu_get_ccount() from esp_cpu.h. Users should call esp_cpu_get_cycle_count() instead.
- Remove esp_cpu_set_ccount() from esp_cpu.h. Users should call esp_cpu_set_cycle_count() instead.
- Other IDF components updated to call esp_cpu_dbgr_is_attached(), esp_cpu_get_cycle_count() and esp_cpu_set_cycle_count() as well.
SMP FreeRTOS uses a single kernel lock for all critical sections. There is a known
issue with esp_ipc_isr_stall_other_cpu() that can cause dead if the other CPU is
already in a critical section.
This commit adds a temporary workaround to reduce the chance of deadlock by taking
the SMP FreeRTOS kernel lock first before stalling the other CPU.
See IDF-5257 for more details.

The problem with the new format is that it is hard to parse and
breaks the parser that is used by PlatformIO. The old format
is much more reasonable. I do not see how the pattern in IDFDUT.py
can work with the new format, due to the missing space after the :
The behavior of portSET_INTERRUPT_MASK_FROM_ISR() has changed in SMP FreeRTOS. It's
previous behavior is now implemented in portDISABLE_INTERRUPTS() and portRESTORE_INTERRUPTS().
This commit replaces all portSET_INTERRUPT_MASK_FROM_ISR() and portCLEAR_INTERRUPT_MASK_FROM_ISR()
calls with portDISABLE_INTERRUPTS() and portRESTORE_INTERRUPTS() respectively
This commit updates the visibility of various header files and cleans up
some unnecessary inclusions. Also, this commit removes certain header
include paths which were maintained for backward compatibility.
This commit removes the usage of all legacy FreeRTOS data types that
are exposed via configENABLE_BACKWARD_COMPATIBILITY. Legacy types can
still be used by enabling CONFIG_FREERTOS_ENABLE_BACKWARD_COMPATIBILITY.
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.
