freertos: Move some SMP FreeRTOS functions to flash The CONFIG_FREERTOS_PLACE_FUNCTIONS_INTO_FLASH allows some FreeRTOS functions to be placed into flash, thus saving some IRAM. However, this feature was previously not supported for SMP FreeRTOS. This commit adds CONFIG_FREERTOS_PLACE_FUNCTIONS_INTO_FLASH support for SMP FreeRTOS. There are now separate linker fragment files for IDF FreeRTOS and SMP FreeRTOS, named "linker.lf" and "linker_smp.lf" respectively.

Task WDT: Interuptee task stack is now used for backtracing, regardless of the CPU core For RISC-V and Xtensa targets, in case a panic needs to happen when Task WDT is triggered (ESP_TASK_WDT_PANIC), the interruptee's stack is now used for printing the backtrace. Abort after Task Watchdog is triggered can happen on APP CPU (second core).

freertos(IDF): Remove dependency on portUSING_MPU_WRAPPERS This commit removes the dependency on portUSING_MPU_WRAPPERS on the Xtensa port of IDF FreeRTOS. This dependency was added due to a hack implemented in the upstream port that required the usage of the "xMPUSettings" member of the TCB. The "xMPUSettings" would be used as a pointer to the task's coprocessor save area on the stack, even though FreeRTOS MPU support was not available. The hack has now been removed, and the CPSA pointer is now calculated using a combination of constant offsets values and the pxEndOfStack member of the TCB. Note: This impelemtation was copied from the Xtensa port of Amazon SMP FreeRTOS.

freertos: Remove/restore queue locks for multi-core/single-core This commit removes the updates the usage of queue locks in IDF FreeRTOS Queue locks are present in Vanilla FreeRTOS to ensure that queue functions behave deterministicly in critical sections (i.e., no walking linked lists while interrupts are disabled). However, currently in IDF FreeRTOS... - When configNUM_CORES > 1, IDF FreeRTOS drops the determinism requirement. Thus, queue functions could be simplified if queue locks were not used at all (and have a queue function do everything inside the same critical section). - When configNUM_CORES == 1, the current queue implementation in IDF FreeRTOS does not meet the determinism requirements, as critical sections are used (instead of scheduler suspension) when locking/unlocking the queues. There, this commit updates multiple queue functions so that - When configNUM_CORES > 1 - Queue locks are no longer used. All actions are done within the same critical section. - Affected queue functions now need 40% less CPU clock cycles when blocking - When configNUM_CORES = 1 - Queue locks are still used. - Vanilla behavior of suspending the scheduler is restored when locking the queue. Thus queue fucntions are now deterministic and have the same behavior as Vanilla FreeRTOS. - Affected queue functions now takes 36% more CPU clock cycles when blocking (due to the scheduler suspension/resumption).

freertos: Refactor OS startup functions This commit refactors the OS startup functions as follows: - Moved the OS/app startup functions listed below to "app_startup.c". Their implementations are now common to all ports (RISC-V and Xtensa) of all FreeRTOS implementations (IDF and Amazon SMP). - esp_startup_start_app() - esp_startup_start_app_other_cores() - Removed esp_startup_start_app_common() as app startup functions are now already common to all ports. - Added extra logs to "main_task" to help with user debugging Note: Increased startup delay on "unity_task". The "unity_run_menu()" is non blocking, thus if the main task or other startup tasks have not been freed by the time "unity_run_menu()" is run, those tasks will be freed the next time "unity_task" blocks. This could cause some tests to have a memory leak, thus the "unity_task" startup delay has increased.

freertos: Move some port functions into flash by default This commit places some functions in port.c and port_common.c into flash by default. These functions are mostly called once during startup, thus shouldn't affect applications much when placed into flash instead of the default IRAM.
