+
+## General Workflow
+
+1. Push to a remote branch
+2. Create an MR, choose related labels (not required)
+3. A `detached` pipeline will be created.
+4. if you push a new commit, a new pipeline will be created automatically.
+
+## What if Expected Jobs ARE NOT Created?
+
+1. check the file patterns
+
+   If you found a job that is not running as expected with some file changes, a git commit to improve the `pattern` will be appreciated.
+
+2. please add MR labels to run additional tests, currently we have to do this only for `target-test` jobs, please use it as few as possible. Our final goal is to remove all the labels and let the file changes decide everything!
+
+## MR labels for additional jobs
+
+### Supported MR Labels
+
+- `build`
+- `build_docs`
+- `component_ut[_esp32/esp32s2/...]`
+- `custom_test[_esp32/esp32s2/...]`
+- `docker`
+- `docs`
+- `docs_fast`, triggers a fast docs build, not a full build which is the CI default. This skips PDF build as well as doxygen APIs, reducing the build time by 90+%.
+- `example_test[_esp32/esp32s2/...]`
+- `fuzzer_test`
+- `host_test`
+- `integration_test`
+- `iperf_stress_test`
+- `macos`
+- `macos_test`
+- `nvs_coverage`
+- `submodule`
+- `unit_test[_esp32/esp32s2/...]`
+- `weekend_test`
+- `windows`
+
+There are two general labels (not recommended since these two labels will trigger a lot of jobs)
+
+- `target_test`: includes all target for `example_test`, `custom_test`, `component_ut`, `unit_test`, `integration_test`
+- `all_test`: includes all test labels
+
+### How to trigger a `detached` pipeline without pushing new commits?
+
+Go to MR web page -> `Pipelines` tab -> click `Run pipeline` button.
+
+In very rare case, this tab will not show up because no merge_request pipeline is created before. Please use web API then.
+
+```shell
+curl -X POST --header "PRIVATE-TOKEN: [YOUR PERSONAL ACCESS TOKEN]" [GITLAB_SERVER]/api/v4/projects/103/merge_requests/[MERGE_REQUEST_IID]/pipelines
+```
+
+## How to Develop With `rules.yml`?
+
+### General Concepts
+
+- `pattern`: Defined in an array. A GitLab job will be created if the changed files in this MR matched one of the patterns. For example:
+
+    ```yaml
+    .patterns-python-files: &patterns-python-files
+      - "**/*.py"
+    ```
+
+- `label`: Defined in an if clause, similar as the previous bot command. A GitLab job will be created if the pipeline variables contains variables in `BOT_LABEL_xxx` format (DEPRECATED) or included in the MR labels. For example:
+
+    ```yaml
+    .if-label-build_docs: &if-label-build_docs
+      if: '$BOT_LABEL_BUILD_DOCS || $CI_MERGE_REQUEST_LABELS =~ /^(?:[^,\n\r]+,)*build_docs(?:,[^,\n\r]+)*$/i'
+    ```
+
+- `rule`: A combination of various patterns, and labels. It will be used by GitLab YAML `extends` keyword to tell GitLab in what conditions will this job be created. For example:
+
+    ```yaml
+    .rules:build:docs:
+      rules:
+        - <<: *if-protected
+        - <<: *if-label-build_docs
+        - <<: *if-label-docs
+        - <<: *if-dev-push
+          changes: *patterns-docs
+    ```
+
+  An example for GitLab job on how to use extends:
+
+    ```yaml
+    check_docs_lang_sync:
+      extends:
+        - .pre_check_job_template
+        - .rules:build:docs
+      script:
+        - cd docs
+        - ./check_lang_folder_sync.sh
+    ```
+
+### How to Add a New `Job`?
+
+check if there's a suitable `.rules:<rules-you-need>` template
+
+1. if there is, put this in the job `extends`. All done, now you can close this window. (`extends` could be array or string)
+2. if there isn't
+    1. check [How to Add a New `Rules` Template?](#how-to-add-a-new-rules-template), create a suitable one
+    2. follow step 1
+
+### How to Add a New `Rules` Template?
+
+check if this rule is related to `labels`, `patterns`
+
+1. if it is, please refer to [dependencies/README.md](./dependencies/README.md) and add new rules by auto-generating
+2. if it isn't, please continue reading
+
+check if there's a suitable `.if-<if-anchor-you-need>` anchor
+
+1. if there is, create a rule following [`rules` Template Naming Rules](#rules-template-naming-rules).For detail information, please refer to [GitLab Documentation `rules-if`](https://docs.gitlab.com/ee/ci/yaml/README.html#rulesif). Here's an example.
+
+    ```yaml
+    .rules:dev:
+      rules:
+        - <<: *if-trigger
+        - <<: *if-dev-push
+    ```
+
+2. if there isn't
+
+    1. check [How to Add a New `if` Anchor?](#how-to-add-a-new-if-anchor), create a suitable one
+    2. follow step 1
+
+### How to Add a New `if` Anchor?
+
+Create an `if` anchor following [`if` Anchors Naming Rules](#if-anchors-naming-rules). For detailed information about how to write the condition clause, please refer to [GitLab Documentation `only/except (advanced)](https://docs.gitlab.com/ee/ci/yaml/README.html#onlyexcept-advanced). Here's an example.
+
+```yaml
+.if-schedule: &if-schedule:
+  if: '$CI_PIPELINE_SOURCE == "schedule"'
+```
+
+### Naming Rules
+
+#### Common Naming Rules
+
+if a phrase has multi words, use `_` to concatenate them.
+
+> e.g. `regular_test`
+
+if a name has multi phrases, use `-` to concatenate them.
+
+> e.g. `regular_test-example_test`
+
+#### `if` Anchors Naming Rules
+
+- if it's a label: `.if-label-<label_name>`
+- if it's a ref: `.if-ref-<ref_name>`
+- if it's a branch: `.if-branch-<branch_name>`
+- if it's a tag: `.if-tag-<tag_name>`
+- if it's multi-type combination: `.if-ref-<release_name>-branch-<branch_name>`
+
+  **Common Phrases/Abbreviations**
+
+    - `no_label`
+
+      `$BOT_TRIGGER_WITH_LABEL == null`
+
+    - `protected`
+
+      `($CI_COMMIT_REF_NAME == "master" || $CI_COMMIT_BRANCH =~ /^release\/v/ || $CI_COMMIT_TAG =~ /^v\d+\.\d+(\.\d+)?($|-)/)`
+
+    - `target_test`
+
+      a combination of `example_test`, `custom_test`, `unit_test`, `component_ut`, `integration_test` and all targets
+
+#### `rules` Template Naming Rules
+
+- if it's tag related: `.rules:tag:<tag_1>-<tag_2>`
+- if it's label related: `.rules:labels:<label_1>-<label_2>`
+- if it's test related: `.rules:test:<test_type>`
+- if it's build related: `.rules:build:<build_type>`
+- if it's pattern related: `.rules:patterns:<patterns>`
+
+## Reusable Shell Script `tools/ci/utils.sh`
+
+It is used to put all the reusable shell scripts as small functions. If you want to set `before_script: []` for you job, now you can set `extends: .before_script_slim` instead. it will only run `source tools/ci/utils.sh`
+
+If you're developing CI shell scripts, you can use these functions without `source` them. They're already included in all `before_script`
+
+To run these commands in shell script locally, place `source tools/ci/utils.sh` at the very beginning.
+
+### Functions
+
+#### CI Job Related
+
+- `add_gitlab_ssh_keys`
+- `add_github_ssh_keys`
+- `add_doc_server_ssh_keys`
+- `fetch_submodules`
+- `get_all_submodules`
+
+#### Shell Script Related
+
+- `error`: log in red color
+- `warning`: log in orange color
+- `info`: log in green color
+- `run_cmd`: run the command with duration seconds info
+- `retry_failed`: run the command with duration seconds info, retry when failed
+
+## Manifest File to Control the Build/Test apps
+
+`.build-test-rules.yml` file is a manifest file to control if the CI is running the build and test job or not. The Supported Targets table in `README.md` for apps would be auto-generated by `pre-commit` from the app's `.build-test-rules.yml`.
+
+### Grammar
+
+#### Operands
+
+- Variables start with `SOC_`. The value would be parsed from components/soc/[TARGET]/include/soc/*_caps.h
+- `IDF_TARGET`
+- `INCLUDE_DEFAULT` (The default value of officially supported targets is 1, otherwise is 0)
+- String, must be double-quoted. e.g. `"esp32"`, `"12345"`
+- Integer, support decimal and hex. e.g. `1`, `0xAB`
+- List with String and Integer inside, the type could be mixed. e.g. `["esp32", 1]`
+
+#### Operators
+
+- `==`, `!=`, `>`, `>=`, `<`, `<=`
+- `and`, `or`
+- `in`, `not in` with list
+- parentheses
+
+#### Limitation:
+
+- all operators are binary operator. For more than two operands, you may use nested parentheses trick. For example,
+  - `A == 1 or (B == 2 and C in [1,2,3])`
+  - `(A == 1 and B == 2) or (C not in ["3", "4", 5])`
+
+### How does it work?
+
+By default, we enable build and test jobs for supported targets. In other words, if an app supports all supported targets, it does not need to be added in a manifest file. The manifest files are files that set the violation rules for apps.
+
+three rules (disable rules are calculated after the `enable` rule):
+- enable: run CI build/test jobs for targets that match any of the specified conditions only
+- disable: will not run CI build/test jobs for targets that match any of the specified conditions
+- disable_test: will not run CI test jobs for targets that match any of the specified conditions
+
+Each key is a test folder. Will apply to all folders inside.
+
+If one sub folder is in a special case, you can overwrite the rules for this folder by adding another entry for this folder itself. Each folder's rules are standalone, and will not inherit its parent's rules. (YAML inheritance is too complicated for reading)
+
+For example in the following codeblock, only `disable` rule exists in `examples/foo/bar`. It's unaware of its parent's `enable` rule. 
+
+```yaml
+examples/foo:
+  enable:
+    - if: IDF_TARGET == "esp32"
+
+examples/foo/bar:
+  disable:
+    - if: IDF_TARGET == "esp32s2"
+```
+
+### Example
+
+```yaml
+examples/foo:
+  enable:
+    - if IDF_TARGET in ["esp32", 1, 2, 3]
+    - if IDF_TARGET not in ["4", "5", 6]
+  # should be run under all targets!
+
+examples/bluetooth:
+  disable:  # disable both build and tests jobs
+    - if: SOC_BT_SUPPORTED != 1
+    # reason is optional if there's no `temporary: true`
+  disable_test:
+    - if: IDF_TARGET == "esp32"
+      temporary: true
+      reason: lack of ci runners  # required when `temporary: true`
+
+examples/bluetooth/test_foo:
+  # each folder's settings are standalone
+  disable:
+    - if: IDF_TARGET == "esp32s2"
+      temporary: true
+      reason: no idea
+  # unlike examples/bluetooth, the apps under this folder would not be build nor test for "no idea" under target esp32s2
+
+examples/get-started/hello_world:
+  enable:
+    - if: IDF_TARGET == "linux"
+      reason: this one only supports linux!
+
+examples/get-started/blink:
+  enable:
+    - if: INCLUDE_DEFAULT == 1 or IDF_TARGET == "linux"
+      reason: This one supports all supported targets and linux

+# How the `generate_rules.py` works
+
+## Functionalities
+
+This script can do only two things:
+
+1. Auto-generate some labels/rules we need and update them in `rules.yml`
+2. Generate a dependency tree graph
+
+## Schema
+
+This file only used basic YAML grammar and has nothing to do with the GitLab version YAML file.
+
+It has five custom keywords:
+
+- `matrix`: An array of sub-arrays, used to replicate rules by formatting strings. You can use the format string everywhere, it will be formatted recursively
+- `labels`: An array of `labels`.
+- `patterns`: An array of `patterns`. Patterns that not included
+- `included_in`: An array of other `rule` names. It indicates the `labels` and `patterns` will be included in all specified `rules` as well
+- `deploy`: An array of strings, used to replicate rules by adding postfix `-<item in deploy array>`. It indicates the extra `label` used in `rules`, which will explain later.
+
+## How to use this file to generate `rules.yml`
+
+Let's take a complicated example to help understand the process
+
+```yaml
+"test-{0}-{1}":
+    matrix:
+        - [a, b]
+        - [c, d]
+    labels:
+        - "{0}-{1}"
+    patterns:
+        - "{0}"
+        - pattern-not-exist
+    included_in:
+        - build-{0}
+```
+
+1. expand the mapping dicts defined by `matrix`
+
+   After this step, it will turn into 4 dicts:
+
+   | key      | labels | patterns | included_in |
+   | -------- | ------ | -------- | ----------- |
+   | test-a-c | a-c    | a        | build-a     |
+   | test-a-d | a-d    | a        | build-a     |
+   | test-b-c | b-c    | b        | build-b     |
+   | test-b-d | b-d    | b        | build-b     |
+
+   **Advanced Usage: You can overwrite a mapping by declaring it again later**, For example:
+
+   If we concatenate this part to the previous example,
+
+    ```yaml
+    # ... The same as the previous example
+    
+    test-a-c:
+        labels:
+            - overwrite
+    ```
+
+   `rule` `test-a-c` will be turned into:
+
+   | key      | labels    |
+   | -------- | --------- |
+   | test-a-c | overwrite |
+
+   **Mappings with the keyword `deploy` will also replicate by adding a postfix `-<item in deploy array>` to the mapping key**
+
+2. create rules by `included_in`
+
+   After this step, it will turn into 6 mapping dicts:
+
+   | key      | labels   | patterns |
+   | -------- | -------- | -------- |
+   | test-a-c | a-c      | a        |
+   | test-a-d | a-d      | a        |
+   | test-b-c | b-c      | b        |
+   | test-b-d | b-d      | b        |
+   | build-a  | a-c, a-d | a        |
+   | build-b  | b-c, b-d | b        |
+
+3. replace the auto-generated region in `rules.yml` with `labels`, and `rules`. Each mapping will generate a `rule` and all the required labels. `patterns` are pre-defined in `rules.yml` and could not be generated automatically. If a mapping is using a `pattern` undefined, the `pattern` will be ignored.
+
+    - If a mapping key has postfix `-preview`, no `if-protected-xxx` clause will be added
+    - else if a mapping key has postfix `-production`, an `if-protected-no_label` clause will be added
+    - else, an `if-protected` clause will be added
+
+## Graph
+
+All `label` nodes are in green, `pattern` nodes are in cyan, `rule` nodes are in blue
+
+### Requirements
+
+There are a few extra dependencies while generating the dependency tree graph, please refer to [pygraphviz](https://github.com/pygraphviz/pygraphviz/blob/master/INSTALL.txt) documentation to install both `graphviz` and `pygraphviz`
+
+### CLI usage
+
+`python generate_rules.py --graph OUTPUT_PATH`

-Contributions to esp-idf - fixing bugs, adding features, adding documentation - are welcome. We accept contributions via `Github Pull Requests <https://help.github.com/en/github/collaborating-with-issues-and-pull-requests/about-pull-requests>`_.
-
-Before Contributing
--------------------
-
-Before sending us a Pull Request, please consider this list of points:
-
-* Is the contribution entirely your own work, or already licensed under an Apache License 2.0 compatible Open Source License? If not then we unfortunately cannot accept it.
-
-* Does any new code conform to the esp-idf :doc:`Style Guide <style-guide>`?
-
-* Have you installed the :doc:`pre-commit hook <install-pre-commit-hook>` for esp-idf project?
-
-* Does the code documentation follow requirements in :doc:`documenting-code`?
-
-* Is the code adequately commented for people to understand how it is structured?
-
-* Is there documentation or examples that go with code contributions? There are additional suggestions for writing good examples in :idf:`examples` readme.
-
-* Are comments and documentation written in clear English, with no spelling or grammar errors?
-
-* Example contributions are also welcome. Please check the :doc:`creating-examples` guide for these.
-
-* If the contribution contains multiple commits, are they grouped together into logical changes (one major change per pull request)? Are any commits with names like "fixed typo" `squashed into previous commits <https://eli.thegreenplace.net/2014/02/19/squashing-github-pull-requests-into-a-single-commit/>`_?
-
-* If you're unsure about any of these points, please open the Pull Request anyhow and then ask us for feedback.
-
-Pull Request Process
---------------------
-
-After you open the Pull Request, there will probably be some discussion in the comments field of the request itself.
-
-Once the Pull Request is ready to merge, it will first be merged into our internal git system for in-house automated testing.
-
-If this process passes, it will be merged onto the public github repository.
-
-Legal Part
-----------
-
-Before a contribution can be accepted, you will need to sign our :doc:`contributor-agreement`. You will be prompted for this automatically as part of the Pull Request process.

+# Core Components
+
+## Overview
+
+This document contains details about what the core components are, what they contain, and how they are organized.
+
+## Organization
+
+The core components are organized into two groups.
+
+The first group (referred to as `G0` from now on) contains `hal`, `xtensa` and `riscv` (referred to as `arch` components from now on), `esp_rom`, `esp_common`, and `soc`. This
+group contain information about and low-level access to underlying hardware; or in the case of `esp_common`, hardware-agnostic code and utilities.
+These components can depend on each other, but as much as possible have no dependencies outside the group. The reason for this is that, due to the
+nature of what these components contain, the likelihood is high that a lot of other components will require these. Ideally, then, the dependency
+relationship only goes one way. This makes it easier for these components, as a group, to be usable in another project. One can conceivably implement
+a competing SDK to ESP-IDF on top of these components.
+
+The second group (referred to as `G1` from now on) sits at a higher level than the first group. This group contains the components `esp_hw_support`, `esp_system`, `newlib`, `spi_flash`,
+`freertos`, `log`, and `heap`. Like the first group, circular dependencies within the group are allowed; and being at a higher level, dependency on the first group
+is allowed. These components represent software mechanisms essential to building other components.

+The following is a short description of the components mentioned above.
+
+### `G0` Components
+
+#### `hal`
+
+Contains the hardware abstraction layer and low-level operation implementations for the various peripherals. The low-level functions assign meaningful names to register-level manipulations; the hardware abstraction provide operations one level above this, grouping these low-level functions
+into routines that achieve a meaningful action or state of the peripheral.
+
+Example:
+
+- `spi_flash_ll_set_address` is a low-level function part of the hardware abstraction `spi_flash_hal_read_block`
+
+#### `arch`
+
+Contains low-level architecture operations and definitions, including those for customizations (can be thought of on the same level as the low-level functions of `hal`).
+This can also contain files provided by the architecture vendor.
+
+Example:
+
+- `xt_set_exception_handler`
+- `riscv_global_interrupts_enable`
+- `ERI_PERFMON_MAX`
+
+#### `esp_common`
+
+Contains hardware-agnostic definitions, constants, macros, utilities, 'pure' and/or algorithmic functions that is useable by all other components (that is, barring there being a more appropriate component to put them in).
+
+Example:
+
+- `BIT(nr)` and other bit manipulation utilities in the future
+- `IDF_DEPRECATED(REASON)`
+- `ESP_IDF_VERSION_MAJOR`
+
+#### `soc`
+
+Contains description of the underlying hardware: register structure, addresses, pins, capabilities, etc.
+
+Example:
+
+- `DR_REG_DPORT_BASE`
+- `SOC_MCPWM_SUPPORTED`
+- `uart_dev_s`
+
+#### `esp_rom`
+
+Contains headers, linker scripts, abstraction layer, patches, and other related files to ROM functions.
+
+Example:
+
+- `esp32.rom.eco3.ld`
+- `rom/aes.h`
+
+### `G1` Components
+
+#### `spi_flash`
+
+SPI flash device access implementation.
+
+#### `freertos`
+
+FreeRTOS port to targets supported by ESP-IDF.
+
+#### `log`
+
+Logging library.
+
+#### `heap`
+
+Heap implementation.
+
+#### `newlib`
+
+Some functions n the standard library are implemented here, especially those needing other `G1` components.
+
+Example:
+
+- `malloc` is implemented in terms of the component `heap`'s functions
+- `gettimeofday` is implemented in terms of system time in `esp_system`
+
+#### `esp_system`
+
+Contains implementation of system services and controls system behavior. The implementations
+here may take hardware resources and/or decide on a hardware state needed for support of a system service/feature/mechanism.
+Currently, this encompasses the following, but not limited to:
+
+- Startup and initialization
+- Panic and debug
+- Reset and reset reason
+- Task and interrupt watchdogs
+
+#### `esp_hw_support`
+
+Contains implementations that provide hardware operations, arbitration, or resource sharing, especially those that
+is used in the system. Unlike `esp_system`, implementations here do not decide on a hardware state or takes hardware resource, acting
+merely as facilitator to hardware access. Currently, this encompasses the following, but not limited to:
+
+- Interrupt allocation
+- Sleep functions
+- Memory functions (external SPIRAM, async memory, etc.)
+- Clock and clock control
+- Random generation
+- CPU utilities
+- MAC settings
+
+### `esp_hw_support` vs `esp_system`
+
+This section details list some implementations and the reason for placing it in either `esp_hw_support` or `esp_system`.
+
+#### `task_wdt.c` (`esp_system`) vs  `intr_alloc.c` (`esp_hw_support`)
+
+The task watchdog fits the definition of taking and configuring hardware resources (wdt, interrupt) for implementation of a system service/mechanism.
+
+This is in contrast with interrupt allocation that merely facilitates access to the underlying hardware for other implementations -
+drivers, user code, and even the task watchdog mentioned previously!
+
+#### `crosscore_int.c` (`esp_system`)
+
+The current implementation of crosscore interrupts is tightly coupled with a number of interrupt reasons
+associated with system services/mechanisms: REASON_YIELD (scheduler), REASON_FREQ_SWITCH (power management)
+REASON_PRINT_BACKTRACE (panic and debug).
+
+However, if an implementation exists that makes it possible to register an arbitrary interrupt reason - a
+lower level inter-processor call if you will, then this implementation is a good candidate for `esp_hw_support`.
+The current implementation in `esp_system` can then just register the interrupt reasons mentioned above.
+
+#### `esp_mac.h`, `esp_chip_info.h`, `esp_random.h` (`esp_hw_support`)
+
+The functions in these headers used to be in `esp_system.h`, but have been split-off.
+
+The remaining functions in `esp_system.h` are those that deal with system behavior, such
+as `esp_register_shutdown_handler`, or are proxy for other system components's APIs such as
+`esp_get_free_heap_size`.
+
+The functions split-off from `esp_system.h` are much more hardware manipulation oriented such as:
+`esp_read_mac`, `esp_random` and `esp_chip_info`.

+// How It Works
+// ************
+
+// 1. Components Overview
+// ======================
+
+// Xtensa has useful feature: TRAX debug module. It allows recording program execution flow at run-time without disturbing CPU.
+// Exectution flow data are written to configurable Trace RAM block. Besides accessing Trace RAM itself TRAX module also allows to read/write
+// trace memory via its registers by means of JTAG, APB or ERI transactions.
+// ESP32 has two Xtensa cores with separate TRAX modules on them and provides two special memory regions to be used as trace memory.
+// Chip allows muxing access to those trace memory blocks in such a way that while one block is accessed by CPUs another one can be accessed by host
+// by means of reading/writing TRAX registers via JTAG. Blocks muxing is configurable at run-time and allows switching trace memory blocks between
+// accessors in round-robin fashion so they can read/write separate memory blocks without disturbing each other.
+// This module implements application tracing feature based on above mechanisms. It allows to transfer arbitrary user data to/from
+// host via JTAG with minimal impact on system performance. This module is implied to be used in the following tracing scheme.
+
+//                                                        ------>------                                         ----- (host components) -----

+
+// In general tracing goes in the following way. User application requests tracing module to send some data by calling esp_apptrace_buffer_get(),
+// module allocates necessary buffer in current input trace block. Then user fills received buffer with data and calls esp_apptrace_buffer_put().
+// When current input trace block is filled with app data it is exposed to host and the second block becomes input one and buffer filling restarts.
+// While target application fills one TRAX block host reads another one via JTAG.
+// This module also allows communication in the opposite direction: from host to target. As it was said ESP32 and host can access different TRAX blocks
+// simultaneously, so while target writes trace data to one block host can write its own data (e.g. tracing commands) to another one then when
+// blocks are switched host receives trace data and target receives data written by host application. Target user application can read host data
+// by calling esp_apptrace_read() API.
+// To control buffer switching and for other communication purposes this implementation uses some TRAX registers. It is safe since HW TRAX tracing
+// can not be used along with application tracing feature so these registers are freely readable/writeable via JTAG from host and via ERI from ESP32 cores.
+// Overhead of this implementation on target CPU is produced only by allocating/managing buffers and copying of data.
+// On the host side special OpenOCD command must be used to read trace data.
+
+// 2. TRAX Registers layout
+// ========================
+
+// This module uses two TRAX HW registers to communicate with host SW (OpenOCD).
+//  - Control register uses TRAX_DELAYCNT as storage. Only lower 24 bits of TRAX_DELAYCNT are writable. Control register has the following bitfields:
+//   | 31..XXXXXX..24 | 23 .(host_connect). 23| 22..(block_id)..15 | 14..(block_len)..0 |
+//    14..0  bits - actual length of user data in trace memory block. Target updates it every time it fills memory block and exposes it to host.
+//                  Host writes zero to this field when it finishes reading exposed block;
+//    21..15 bits - trace memory block transfer ID. Block counter. It can overflow. Updated by target, host should not modify it. Actually can be 2 bits;
+//    22     bit  - 'host data present' flag. If set to one there is data from host, otherwise - no host data;
+//    23     bit  - 'host connected' flag. If zero then host is not connected and tracing module works in post-mortem mode, otherwise in streaming mode;
+// - Status register uses TRAX_TRIGGERPC as storage. If this register is not zero then current CPU is changing TRAX registers and
+//   this register holds address of the instruction which application will execute when it finishes with those registers modifications.
+//   See 'Targets Connection' setion for details.
+
+// 3. Modes of operation
+// =====================
+
+// This module supports two modes of operation:
+//  - Post-mortem mode. This is the default mode. In this mode application tracing module does not check whether host has read all the data from block
+//    exposed to it and switches block in any case. The mode does not need host interaction for operation and so can be useful when only the latest
+//    trace data are necessary, e.g. for analyzing crashes. On panic the latest data from current input block are exposed to host and host can read them.
+//    It can happen that system panic occurs when there are very small amount of data which are not exposed to host yet (e.g. crash just after the
+//    TRAX block switch). In this case the previous 16KB of collected data will be dropped and host will see the latest, but very small piece of trace.
+//    It can be insufficient to diagnose the problem. To avoid such situations there is menuconfig option
+//    CONFIG_APPTRACE_POSTMORTEM_FLUSH_THRESH
+//    which controls the threshold for flushing data in case of panic.
+//  - Streaming mode. Tracing module enters this mode when host connects to target and sets respective bits in control registers (per core).
+//    In this mode before switching the block tracing module waits for the host to read all the data from the previously exposed block.
+//    On panic tracing module also waits (timeout is configured via menuconfig via CONFIG_APPTRACE_ONPANIC_HOST_FLUSH_TMO) for the host to read all data.
+
+// 4. Communication Protocol
+// =========================
+
+// 4.1 Trace Memory Blocks
+// -----------------------
+
+// Communication is controlled via special register. Host periodically polls control register on each core to find out if there are any data available.
+// When current input memory block is filled it is exposed to host and 'block_len' and 'block_id' fields are updated in the control register.
+// Host reads new register value and according to it's value starts reading data from exposed block. Meanwhile target starts filling another trace block.
+// When host finishes reading the block it clears 'block_len' field in control register indicating to the target that it is ready to accept the next one.
+// If the host has some data to transfer to the target it writes them to trace memory block before clearing 'block_len' field. Then it sets
+// 'host_data_present' bit and clears 'block_len' field in control register. Upon every block switch target checks 'host_data_present' bit and if it is set
+// reads them to down buffer before writing any trace data to switched TRAX block.
+
+// 4.2 User Data Chunks Level
+// --------------------------
+
+// Since trace memory block is shared between user data chunks and data copying is performed on behalf of the API user (in its normal context) in
+// multithreading environment it can happen that task/ISR which copies data is preempted by another high prio task/ISR. So it is possible situation
+// that task/ISR will fail to complete filling its data chunk before the whole trace block is exposed to the host. To handle such conditions tracing
+// module prepends all user data chunks with header which contains allocated buffer size and actual data length within it. OpenOCD command
+// which reads application traces reports error when it reads incomplete user data block.
+// Data which are transffered from host to target are also prepended with a header. Down channel data header is simple and consists of one two bytes field
+// containing length of host data following the header.
+
+// 4.3 Data Buffering
+// ------------------
+
+// It takes some time for the host to read TRAX memory block via JTAG. In streaming mode it can happen that target has filled its TRAX block, but host
+// has not completed reading of the previous one yet. So in this case time critical tracing calls (which can not be delayed for too long time due to
+// the lack of free memory in TRAX block) can be dropped. To avoid such scenarios tracing module implements data buffering. Buffered data will be sent
+// to the host later when TRAX block switch occurs. The maximum size of the buffered data is controlled by menuconfig option
+// CONFIG_APPTRACE_PENDING_DATA_SIZE_MAX.
+
+// 4.4 Target Connection/Disconnection
+// -----------------------------------
+
+// When host is going to start tracing in streaming mode it needs to put both ESP32 cores into initial state when 'host connected' bit is set
+// on both cores. To accomplish this host halts both cores and sets this bit in TRAX registers. But target code can be halted in state when it has read control
+// register but has not updated its value. To handle such situations target code indicates to the host that it is updating control register by writing
+// non-zero value to status register. Actually it writes address of the instruction which it will execute when it finishes with
+// the registers update. When target is halted during control register update host sets breakpoint at the address from status register and resumes CPU.
+// After target code finishes with register update it is halted on breakpoint, host detects it and safely sets 'host connected' bit. When both cores
+// are set up they are resumed. Tracing starts without further intrusion into CPUs work.
+// When host is going to stop tracing in streaming mode it needs to disconnect targets. Disconnection process is done using the same algorithm
+// as for connecting, but 'host connected' bits are cleared on ESP32 cores.
+
+// 5. Module Access Synchronization
+// ================================
+
+// Access to internal module's data is synchronized with custom mutex. Mutex is a wrapper for portMUX_TYPE and uses almost the same sync mechanism as in
+// vPortCPUAcquireMutex/vPortCPUReleaseMutex. The mechanism uses S32C1I Xtensa instruction to implement exclusive access to module's data from tasks and
+// ISRs running on both cores. Also custom mutex allows specifying timeout for locking operation. Locking routine checks underlaying mutex in cycle until
+// it gets its ownership or timeout expires. The differences of application tracing module's mutex implementation from vPortCPUAcquireMutex/vPortCPUReleaseMutex are:
+// - Support for timeouts.
+// - Local IRQs for CPU which owns the mutex are disabled till the call to unlocking routine. This is made to avoid possible task's prio inversion.
+//   When low prio task takes mutex and enables local IRQs gets preempted by high prio task which in its turn can try to acquire mutex using infinite timeout.
+//   So no local task switch occurs when mutex is locked. But this does not apply to tasks on another CPU.
+//   WARNING: Priority inversion can happen when low prio task works on one CPU and medium and high prio tasks work on another.
+// WARNING: Care must be taken when selecting timeout values for trace calls from ISRs. Tracing module does not care about watchdogs when waiting
+// on internal locks and for host to complete previous block reading, so if timeout value exceeds watchdog's one it can lead to the system reboot.
+
+// 6. Timeouts
+// ===========
+
+// Timeout mechanism is based on xthal_get_ccount() routine and supports timeout values in microseconds.
+// There are two situations when task/ISR can be delayed by tracing API call. Timeout mechanism takes into account both conditions:
+// - Trace data are locked by another task/ISR. When wating on trace data lock.
+// - Current TRAX memory input block is full when working in streaming mode (host is connected). When waiting for host to complete previous block reading.
+// When wating for any of above conditions xthal_get_ccount() is called periodically to calculate time elapsed from trace API routine entry. When elapsed
+// time exceeds specified timeout value operation is canceled and ESP_ERR_TIMEOUT code is returned.
