esp_system: removed repeated interrupt allocator code and moved common code to esp_system
xtens: moved xtensa specific code from freertos to the xtensa component
hal/interrupt_controller: added interrupt controller hal and ll files
docs: update the doxyfile with new location of esp_itr_alloc.h file
xtensa: fixed dangerous relocation problem after moving xtensa interrupt files out of freertos
docs: removed Xtensa reference from intr_allocator api-reference
xtensa: pushed the interrupt function that manages non iram interrupts to the xtensa layer
esp_system/test: fixed platform dependent setting for intr_allocator tests
hal: rename the functions used to manage non iram interrupt mask.
- Introduce system time function and concept of system time provider.
esp_timer is system time provider when present.
- Set the reference point for system time, g_startup_time.
- Use the system time functions in newlib instead of calling esp_timer
functions directly
Restores the change of startup refactor changes removed the no stack
check protection flag when compiling the source file that contains
execution of constructors - which contains function to setup stack
guard. Restore that and update the source file, since this is in the 2nd
stage of the startup now.
Closes https://github.com/espressif/esp-idf/issues/5617
This MR uses an intermediary function `start_app` to call after system
initialization instead of `app_main`.
In RTOS builds, freertos provides `start_app` and calls `app_main`.
In non-RTOS builds, user provides `start_app` directly.
Changes the startup flow to the ff:
hardware -> core libraries init -> other libraries init -> os
init (optional) -> app_main
- hardware init resides in the port layer, and is the entry point
- core libraries init executes init functions of core components
- other libraries init executes init functions of other components (weak
references)
- after other lib is init, the app_main function is called, however,
an OS can wrap the real call to app_main to init its own stuff, and
*then* call the real app_main
