-## 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_full`, triggers a full docs build, regardless of files changed
-- `example_test[_esp32/esp32s2/...]`
-- `fuzzer_test`
-- `host_test`
-- `integration_test`
-- `iperf_stress_test`
-- `macos`
-- `macos_test`
-- `nvs_coverage`
-- `submodule`
-- `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`, `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_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:patterns:clang_tidy:
-      rules:
-        - <<: *if-protected
-        - <<: *if-dev-push
-          changes: *patterns-c-files
-    ```
-
-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`, `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
-
-We're using the latest version of [idf-build-apps][idf-build-apps]. Please refer to their [documentation][manifest-doc]
-
-[idf-build-apps]: https://github.com/espressif/idf-build-apps
-[manifest-doc]: https://docs.espressif.com/projects/idf-build-apps/en/latest/manifest.html
-
-### Special Rules
-
-In ESP-IDF CI, there's a few more special rules are additionally supported to disable the check app dependencies feature:
-
-- Add MR labels `BUILD_AND_TEST_ALL_APPS`
-- Pipeline variable `IDF_CI_SELECT_ALL_PYTEST_CASES=1`
-- Run in protected branches
-
-## Upload/Download Artifacts to Internal Minio Server

-# 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 $IDF_PATH/tools/ci/generate_rules.py --graph OUTPUT_PATH`

-#
-# The sbom-hash entry records the submodule's checkout SHA as presented in git-tree

-# The submodule SHA recorded here has to match with SHA, which is presented in git-tree.
-# This is checked by CI. Also please don't forget to update the submodule version

-# Compatibility Between ESP-IDF Releases and Revisions of Espressif SoCs
-
-* [中文版](./COMPATIBILITY_CN.md)
-
-Espressif keeps improving the performance of its SoCs by providing new chip revisions. However, some of the improvements require special software support. Some of the software supports are even mandatory for the chip revisions to run normally.
-
-This document describes the compatibility between ESP-IDF releases and Espressif SoC revisions.
-
-NOTE: This document on release branches may be out-of-date. Check the [Compatibility file on master](https://github.com/espressif/esp-idf/blob/master/COMPATIBILITY.md) for the most accurate information.
-
-See [Compatibility Advisory for Chip Revision Numbering Scheme](https://www.espressif.com/sites/default/files/advisory_downloads/AR2022-005%20Compatibility%20Advisory%20for%20Chip%20Revision%20Numbering%20%20Scheme.pdf) on the versioning of Espressif SoC revisions.
-
-You can run `esptool chip-id` to detect the series and revision of an SoC. See [SoC Errata](https://www.espressif.com/en/support/documents/technical-documents?keys=errata) for more on how to distinguish between chip revisions, and the improvements provided by chip revisions. And run `idf.py --version` to know the version of current ESP-IDF.
-
-## ESP-IDF Support for Different Chip Revisions
-
-The sections below show the requirements to ESP-IDF version of chip revisions. Each chip revision corresponds to specific `Recommended` and `Required` versions of ESP-IDF:
-
-- `Recommended`: shows from which version of ESP-IDF you can make use of all the improvements of the chip revision. Running binary compiled with ESP-IDF below the `Recommended` version of a chip revision, software may not benefit from the bugfix/features provided by the chip revision. The chip will have almost the same behavior as its previous revision.
-
-- `Required`: shows the minimum version required to run the chip revision normally. Running binary compiled below the `Required` version, the binary may have unpredictable behavior.
-
-Though the software can make use of all the features of a chip revision, if its version is higher than the `Recommended` version of the chip, it is still recommended to use the latest bugfix version of the release branch. The latest bugfix version fixes a number of issues and helps improve product stability.
-
-For example, if we have a chip, whose `Required`/`Recommended` version of `release/v5.1` branch is `v5.1.2`/`v5.1.4`, and the latest release on that branch is `v5.1.6`. Then the chip will not boot up with ESP-IDF `v5.1`-`v5.1.1` or will have unpredictable behavior, and application may not make use of all benefits of the chip, when running with ESP-IDF `v5.1.2` or `v5.1.3`. Though `v5.1.4` well supports the chip revision, it is still recommended to upgrade ESP-IDF to `v5.1.6`.

-## What If the ESP-IDF Version Is Lower than the `Required` Version?
-
-Latest ESP-IDF versions can prevent from downloading to, or even execute binaries on unsupported chips. ESP-IDF of versions v4.4.5+, v5.0.1+, v5.1 and above have both esptool download check and bootloader loading check against the chip revision. While ESP-IDF v4.3.5 has only esptool downloading check.
-
-For earlier ESP-IDF versions without such checking, which is incompatible with the given chip revision, the chips running such versions will have unpredictable behavior.

-# ESP-IDF 版本与乐鑫芯片版本兼容性
-
-* [English Version](./COMPATIBILITY.md)
-
-为不断提高芯片性能，乐鑫会为其芯片发布新版本。但新芯片版本中的某些性能提升依赖特殊的软件支持，有时候新芯片版本必须在一定的软件版本下才能正常运行。
-
-本文档介绍了具体 ESP-IDF 版本与乐鑫芯片版本之间的兼容性情况。
-
-注意：各分支上的兼容性文档可能不是最新版本，请参考 [master 分支上的兼容性文件](https://github.com/espressif/esp-idf/blob/master/COMPATIBILITY_CN.md) 以获取最新信息。
-
-有关乐鑫芯片版本的编码方式，请参考 [关于芯片版本 (Chip Revision) 编码方式的兼容性公告](https://www.espressif.com/sites/default/files/advisory_downloads/AR2022-005%20%E5%85%B3%E4%BA%8E%E8%8A%AF%E7%89%87%E7%89%88%E6%9C%AC%E7%BC%96%E7%A0%81%E6%96%B9%E5%BC%8F%20%28Chip%20Revision%29%20%E7%9A%84%E5%85%BC%E5%AE%B9%E6%80%A7%E5%85%AC%E5%91%8A.pdf)。
-
-运行 `esptool chip-id` 可查看芯片系列及其版本。有关区分芯片版本及版本改进内容的更多信息，请参考 [芯片勘误表](https://www.espressif.com.cn/zh-hans/support/documents/technical-documents?keys=%E5%8B%98%E8%AF%AF%E8%A1%A8)。运行 `idf.py --version` 可查看当前的 ESP-IDF 版本。
-
-## ESP-IDF 对各芯片版本的支持
-
-下文介绍了 ESP-IDF 对各芯片版本的支持情况，每个芯片版本都有对应的 ESP-IDF `推荐版本` 和 `需求版本`：
-
-- `推荐版本`：表示从该版本的 ESP-IDF 开始，软件可以利用芯片版本提升的性能。如果在该芯片版本上运行低于 `推荐版本` 的 ESP-IDF 来编译二进制文件，软件可能无法利用该芯片版本修复的错误或新增的功能，芯片行为将与其上一版本几乎相同。
-
-- `需求版本`：表示该芯片版本正常运行所需的最低 ESP-IDF 版本。如果在该芯片版本上运行低于 `需求版本` 的 ESP-IDF 来编译二进制文件，可能会出现不可预测的芯片行为。
-
-即便使用的软件版本已高于该芯片版本的对应 `推荐版本`，软件已经能够利用该芯片版本的所有功能，我们仍建议用户升级到该发布分支的最新 bugfix 版本。新的 bugfix 版本修复了一些问题，有助于提升产品稳定性。
-
-例如，对于某一芯片版本，其 `release/v5.1` 分支的 `需求版本` 和 `推荐版本` 分别是 `v5.1.2` 和 `v5.1.4`，而该分支的最新版本是 `v5.1.6`。那么，在使用 ESP-IDF `v5.1` - `v5.1.1` 时，芯片将无法启动，或会出现不可预测的行为，而在使用 ESP-IDF `v5.1.2` 或 `v5.1.3` 时，应用程序可能无法使用芯片的部分性能。此外，虽然 `v5.1.4` 已支持该芯片版本，但仍建议将 ESP-IDF 升级到 `v5.1.6`。

-
-#### v1.0, v1.3
-
-从 ESP-IDF v5.3 开始支持。
-
-## 如果 ESP-IDF 版本低于 `需求版本` 会出现什么情况？
-
-使用最新的 ESP-IDF 版本时，软件会阻止下载二进制文件到不支持的芯片版本上，甚至可以防止二进制文件在不支持的芯片版本上被执行。v4.4.5+、v5.0.1+、v5.1 及以上版本的 ESP-IDF 都支持针对芯片版本的 esptool 下载检查和引导加载器加载检查，但 ESP-IDF v4.3.5 只支持 esptool 下载检查。
-
-更早的 ESP-IDF 版本没有此类检查，若与芯片版本不兼容，芯片运行软件时可能会出现不可预测的行为。

+Contributions Guide
+===================
+
+We welcome contributions to the esp-idf project!
+
+How to Contribute
+-----------------
+
+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>`?
+
+* 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.

 ### Non-GitHub forks
 
-ESP-IDF uses relative locations as its submodules URLs ([.gitmodules](.gitmodules)). So they link to GitHub. If ESP-IDF is forked to a Git repository which is not on GitHub, you will need to run the script [tools/set-submodules-to-github.sh](tools/set-submodules-to-github.sh) after git clone.
-
-The script sets absolute URLs for all submodules, allowing `git submodule update --init --recursive` to complete. If cloning ESP-IDF from GitHub, this step is not needed.

-ESP-IDF 中的子模块采用相对路径（[详见 .gitmodules 文件](.gitmodules)），所以它们会指向 GitHub。 如果 ESP-IDF 被分叉到的仓库不在 GitHub 上，那么你需要在克隆结束后运行该脚本 [tools/set-submodules-to-github.sh](tools/set-submodules-to-github.sh)。
-
-这个脚本会为所有的子模块设置绝对路径，接着可以通过 `git submodule update --init --recursive` 完成子模块的更新。如果 ESP-IDF 是从 GitHub 上克隆得到，则不需要此步骤。

-Support period is divided into "Service" and "Maintenance" period:
+Users are encouraged to upgrade to a newer ESP-IDF release before the
+support period finishes and the release becomes End of Life (EOL). It is
+our policy to not continue fixing bugs in End of Life releases.
 
-| Period      | Duration     | Recommended for new projects?         |
-| -------     | ------------ | ------------------------------------- |
-| Service     | 12 months    | Yes                                   |

+Pre-release versions (betas, previews, `-rc` and `-dev` versions, etc)
+are not covered by any support period. Sometimes a particular feature is
+marked as \"Preview\" in a release, which means it is also not covered
+by the support period.
 
-During the Service period, bugfixes releases are more frequent. In some cases, support for new features may be added during the Service period (this is reserved for features which are needed to meet particular regulatory requirements or standards for new products, and which carry a very low risk of introducing regressions.)
+The ESP-IDF Programming Guide has information about the
+[different versions of ESP-IDF](https://docs.espressif.com/projects/esp-idf/en/latest/versions.html)
+(major, minor, bugfix, etc).
 
-During the Maintenance period, the version is still supported but only bugfixes for high severity issues or security issues will be applied.
+Long Term Support releases
+--------------------------
 
-Using an “In Service” version is recommended when starting a new project.
+Some releases (starting with ESP-IDF V3.3) are designated Long Term
+Support (LTS). LTS releases are supported for 30 months (2.5 years)
+after the initial stable release date.
 
-Users are encouraged to upgrade all projects to a newer ESP-IDF release before the support period finishes and the release becomes End of Life (EOL). It is our policy to not continue fixing bugs in End of Life releases.
-
-Pre-release versions (betas, previews, `-rc` and `-dev` versions, etc) are not covered by any support period. Sometimes a particular feature is marked as "Preview" in a release, which means it is also not covered by the support period.
-
-ESP-IDF should be used in an up-to-date software environment. The operating system and other third-party tools should be supported by their maintainers. ESP-IDF cannot keep compatibility with unsupported third-party tools.
-
-The ESP-IDF Programming Guide has information about the [different versions of ESP-IDF](https://docs.espressif.com/projects/esp-idf/en/latest/versions.html) (major, minor, bugfix, etc).
+A new LTS release will be made at least every 18 months. This means
+there will always be a period of at least 12 months to upgrade from the
+previous LTS release to the following LTS release.

-# 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`) includes `hal`, `arch` (where `arch` is either `riscv` or `xtensa` depending on the chip), `esp_rom`, `esp_common`, and `soc`. This group contains information about and provides low-level access to the underlying hardware. In the case of `esp_common`, it contains hardware-agnostic code and utilities. These components may have dependencies on each other within the group, but outside dependencies should be minimized. The reason for this approach is that these components are fundamental, and many other components may require them. Ideally, the dependency relationship only goes one way, making it easier for this group to be usable in other projects.
-
-The second group (referred to as `G1`) operates at a higher level than the first group. `G1` includes the components `esp_hw_support`, `esp_system`, `esp_libc`, `spi_flash`, `freertos`, `log`, and `heap`. Like the first group, circular dependencies within this group are allowed, and these components can have dependencies on the first group. G1 components represent essential software mechanisms for building other components.
-
-## Descriptions
-
-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`
--   `rv_utils_intr_enable`
--   `ERI_PERFMON_MAX`
-
-#### `esp_common`
-
-Contains hardware-agnostic definitions, constants, macros, utilities, 'pure' and/or algorithmic functions that is usable 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.
-
-#### `esp_libc`
-
-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_mm`
-
-Memory management. Currently, this encompasses:
-
--   Memory mapping for MMU supported memories
--   Memory synchronisation via Cache
--   Utils such as APIs to convert between virtual address and physical address
-
-#### `esp_psram`
-
-Contains implementation of PSRAM services
-
-#### `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.
-// Execution 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 and one Performance Monitor register 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' section for details.
-//  - CRC16 register uses ERI_PERFMON_PM1 as storage. This register is used to store CRC16 checksum of the exposed trace memory block.
-//    The register has the following format:
-//    | 31..16 (CRC indicator) | 15..0 (CRC16 value) |
-//    CRC indicator (0xA55A) is used to distinguish valid CRC values from other data that might be in the register.
-//    CRC16 is calculated over the entire exposed block and is updated every time a block is exposed to the host.
-//    This allows the host to verify data integrity of the received trace data.
-
-// 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 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 underlying 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 waiting 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 waiting 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.
