ffeffcd315 Merge branch 'feature/crosscore_int' into 'master'
Add cross-core int to accelerate task being awoken from another CPU.

This adds a per-CPU interrupt that can be used to poke the CPU to go do something. In this case all that is implemented is a request to yield the current task, used in case a CPU unblocks a task that runs on another CPU. This gets rid of the limitation that inter-CPU communication using queues, muxes etc can take up to a FreeRTOS tick to happen.

Specs!
Sending an in in a queue of length 1 (essentially a semaphore) as quickly as possible (just a small delay in the sender, to make sure the receiver task gets swapped out) for 10 seconds. Number indicates the amount of ints transferred

Old code:

CPU0->CPU0: 42986

CPU0->CPU1,: 2999

New code:

CPU0->CPU0: 42868

CPU0->CPU1: 62073

38c6256db9 Merge branch 'feature/wdts' into 'master'
Feature/wdts

This adds two watchdogs to  esp-idf:

- An interrupt watchdog. Kicks in if the FreeRTOS timer interupt on either the PRO_CPU or (when configured) the APP CPU isn't called for a configurable time. Panics, displaying which CPU caused the problem and the registers that may lead to the offending code.
- A task watchdog. A task has to feed it every once in a while. If not, it will print the name of the offending tasks, as well as the tasks currently running on both CPUs, and optionally panic.

Also adds a panic reason to the panic call, as well as fixes the panic code a bit.

Feature/trax

Add Trax support to esp-idf. OpenOCD already has trax support, this allows an esp-idf program to also trigger this when needed. Also included: some more logic to correctly reserve memory blocks for Trax.

1bae606ccc FreeRTOS KConfig: Limit tick rate to 1000Hz
>1000Hz breaks portTICK_PERIOD_MS (see gitlab 4)

A working >1000Hz tick rate is possible with some changes, but beyond a
certain point it's dimishing returns to preempt tasks this often.

702e749667 Merge branch 'feature/deep_sleep_wake_stub' into 'master'
esp32: Bootloader wake deep sleep stub

App can contain a stub program resident in RTC fast memory. Bootloader
will load the stub on initial boot. If the device wakes from deep sleep,
the stub is run immediately (before any other data is loaded, etc.)

To implement a custom wake stub, implement a function in your program:

```
void RTC_IRAM_ATTR esp_wake_deep_sleep(void)
{
  esp_default_wake_deep_sleep();
  // other wake logic
}
```

... and it will replace the default implementation.

0383bc8599 Merge branch 'workaround/pin_noaffinity_task_to_core_when_fpu_used' into 'master'
Workaround: Automatically pin no-cpu-affinity task to a core when FPU is used

FPU status at the moment does not migrate cleanly between cores, so tasks without affinity that happen to migrate across FPUs will run into problems. As a workaround, this modification will automatically pin the task to the current CPU when FPU activity is detected. If anything, it's better than getting all kinds of weird and wonderful FPU corruption issues...

e3ffcd22d5 Merge branch 'feature/init_refactoring' into 'master'
Startup flow refactoring

This set of commits changes the startup code in a way that lets the application choose if/when to initialize WiFi/BT.

Application entry point is now a more familiar `main()` function. This function is executed in its own task. Application may choose to do some initialization from main function, create some tasks and then return from `main`. Simple applications may choose to do all their work from `main`.

Additionally this MR splits event handling code into two parts. 

- One part is a set of standard handlers for WiFi and DHCP events. Most applications will use this set of handlers, and it is made available via new `esp_event_process_default` function. 
- Another part is the default implementation of event handling loop. Some applications may choose to use default event loop through `esp_event_loop_` set of APIs, which start an event handling task and call user-provided event callback from this task. Other applications may create an event queue and implement event loop themselves. In this case application has to provide `esp_event_send` function. In this case the implementation provided by `esp_event_loop_` module is unused.

esp-idf-template has been updated to match this set of changes: https://github.com/espressif/esp-idf-template/tree/feature/init_refactoring
BT example has also been updated.

We need to provide examples of both event handling approaches. This will be done in a separate follow-up MR.
