+AI Agent 操作手册 - Chat Vault Monorepo
+
+---
+
+## 1. Mission & Scope（目标与边界）
+
+### 允许操作
+- 修改 `services/chat-vault/src/` 下的 Python 代码
+- 添加新的解析器到 `services/chat-vault/src/parsers/`
+- 更新文档 (`README.md`, `AGENTS.md`, `docs/`)
+- 修改配置示例 `.env.example`
+
+### 禁止操作
+- **禁止修改** `output/` 目录下的任何文件（数据库、日志）
+- **禁止修改** `.env` 文件（包含用户敏感配置）
+- **禁止修改** `libs/external/` 下的外部依赖镜像
+- **禁止删除** 现有解析器，除非明确要求
+
+### 敏感区域
+| 路径 | 说明 |
+|------|------|
+| `services/chat-vault/.env` | 用户配置，不得读取或修改 |
+| `services/chat-vault/output/` | 运行时数据，不得修改 |
+| `libs/external/` | 外部镜像，只读 |
+
+---
+
+## 2. Golden Path（推荐执行路径）
+
+```bash
+# 1. 进入服务目录
+cd services/chat-vault
+
+# 2. 首次运行（自动创建 venv 并安装依赖）
+python src/main.py
+
+# 3. 验证功能
+python src/main.py --stats
+
+# 4. 修改代码后测试
+python src/main.py              # 同步测试
+python src/main.py --search "test"  # 搜索测试
+
+# 5. 更新文档（如有变更）
+# 编辑 README.md, AGENTS.md, docs/schema.md
+```
+
+---
+
+## 3. Must-Run Commands（必须执行的命令）
+
+### 环境准备
+```bash
+cd services/chat-vault
+python src/main.py  # 首次运行自动安装依赖
+```
+
+### 依赖文件
+- `services/chat-vault/requirements.txt`
+  ```
+  python-dotenv>=1.0.0
+  watchdog>=3.0.0
+  tiktoken>=0.5.0
+  ```
+
+### 功能验证
+```bash
+# 同步一次
+python src/main.py
+
+# 查看统计
+python src/main.py --stats
+
+# 监控模式
+python src/main.py --watch
+```
+
+---
+
+## 4. Code Change Rules（修改约束）
+
+### 架构原则
+- 解析器必须继承 `parsers/base.py` 的 `SessionData` 数据结构
+- 新增 CLI 支持需在 `parsers/__init__.py` 中导出
+- 配置项通过 `config.py` 的 `CONFIG` 字典访问
+
+### 模块边界
+| 模块 | 职责 | 禁止 |
+|------|------|------|
+| `main.py` | CLI 入口、命令分发 | 不含业务逻辑 |
+| `config.py` | 路径检测、配置加载 | 不含 I/O 操作 |
+| `storage.py` | SQLite 读写、Token 计数 | 不含解析逻辑 |
+| `watcher.py` | 文件监控 | 不含存储逻辑 |
+| `parsers/*.py` | 各 CLI 格式解析 | 不含存储逻辑 |
+
+### 依赖添加规则
+- 新依赖必须添加到 `requirements.txt`
+- 优先使用标准库
+- 避免引入大型框架
+
+### 兼容性要求
+- Python 3.8+ 兼容
+- 跨平台：Linux / macOS / Windows (WSL)
+- WSL 路径格式：`\\wsl.localhost\Ubuntu\...`
+
+---
+
+## 5. Style & Quality（风格与质量）
+
+### 代码风格
+- 文件头：`#!/usr/bin/env python3` + `# -*- coding: utf-8 -*-`
+- 缩进：4 空格
+- 行宽：建议 100 字符
+- 命名：snake_case（函数/变量），PascalCase（类）
+
+### 文档要求
+- 每个模块需有 docstring 说明用途
+- 公开函数需有参数/返回值说明
+- 复杂逻辑需有行内注释
+
+### 错误处理
+- 解析失败记录到日志，不中断流程
+- 使用 `logger.py` 的 `get_logger()` 记录
+

+
+# Contributor Covenant 3.0
+
+## Our Pledge
+
+We pledge to make our community welcoming, safe, and equitable for all.
+
+We are committed to fostering an environment that respects and promotes the dignity, rights, and contributions of all individuals, regardless of characteristics including race, ethnicity, caste, color, age, physical characteristics, neurodiversity, disability, sex or gender, gender identity or expression, sexual orientation, language, philosophy or religion, national or social origin, socio-economic position, level of education, or other status. The same privileges of participation are extended to everyone who participates in good faith and in accordance with this Covenant.
+
+
+## Encouraged Behaviors
+
+While acknowledging differences in social norms, we all strive to meet our community's expectations for positive behavior. We also understand that our words and actions may be interpreted differently than we intend based on culture, background, or native language.
+
+With these considerations in mind, we agree to behave mindfully toward each other and act in ways that center our shared values, including:
+
+1. Respecting the **purpose of our community**, our activities, and our ways of gathering.
+2. Engaging **kindly and honestly** with others.
+3. Respecting **different viewpoints** and experiences.
+4. **Taking responsibility** for our actions and contributions.
+5. Gracefully giving and accepting **constructive feedback**.
+6. Committing to **repairing harm** when it occurs.
+7. Behaving in other ways that promote and sustain the **well-being of our community**.
+
+
+## Restricted Behaviors
+
+We agree to restrict the following behaviors in our community. Instances, threats, and promotion of these behaviors are violations of this Code of Conduct.
+
+1. **Harassment.** Violating explicitly expressed boundaries or engaging in unnecessary personal attention after any clear request to stop.
+2. **Character attacks.** Making insulting, demeaning, or pejorative comments directed at a community member or group of people.
+3. **Stereotyping or discrimination.** Characterizing anyone’s personality or behavior on the basis of immutable identities or traits.
+4. **Sexualization.** Behaving in a way that would generally be considered inappropriately intimate in the context or purpose of the community.
+5. **Violating confidentiality**. Sharing or acting on someone's personal or private information without their permission.
+6. **Endangerment.** Causing, encouraging, or threatening violence or other harm toward any person or group.
+7. Behaving in other ways that **threaten the well-being** of our community.
+
+### Other Restrictions
+
+1. **Misleading identity.** Impersonating someone else for any reason, or pretending to be someone else to evade enforcement actions.
+2. **Failing to credit sources.** Not properly crediting the sources of content you contribute.
+3. **Promotional materials**. Sharing marketing or other commercial content in a way that is outside the norms of the community.
+4. **Irresponsible communication.** Failing to responsibly present content which includes, links or describes any other restricted behaviors.
+
+
+## Reporting an Issue
+
+Tensions can occur between community members even when they are trying their best to collaborate. Not every conflict represents a code of conduct violation, and this Code of Conduct reinforces encouraged behaviors and norms that can help avoid conflicts and minimize harm.
+
+When an incident does occur, it is important to report it promptly. To report a possible violation, **[NOTE: describe your means of reporting here.]**
+
+Community Moderators take reports of violations seriously and will make every effort to respond in a timely manner. They will investigate all reports of code of conduct violations, reviewing messages, logs, and recordings, or interviewing witnesses and other participants. Community Moderators will keep investigation and enforcement actions as transparent as possible while prioritizing safety and confidentiality. In order to honor these values, enforcement actions are carried out in private with the involved parties, but communicating to the whole community may be part of a mutually agreed upon resolution.
+
+
+## Addressing and Repairing Harm
+
+**[NOTE: The remedies and repairs outlined below are suggestions based on best practices in code of conduct enforcement. If your community has its own established enforcement process, be sure to edit this section to describe your own policies.]**
+
+If an investigation by the Community Moderators finds that this Code of Conduct has been violated, the following enforcement ladder may be used to determine how best to repair harm, based on the incident's impact on the individuals involved and the community as a whole. Depending on the severity of a violation, lower rungs on the ladder may be skipped.
+
+1) Warning
+   1) Event: A violation involving a single incident or series of incidents.
+   2) Consequence: A private, written warning from the Community Moderators.
+   3) Repair: Examples of repair include a private written apology, acknowledgement of responsibility, and seeking clarification on expectations.
+2) Temporarily Limited Activities
+   1) Event: A repeated incidence of a violation that previously resulted in a warning, or the first incidence of a more serious violation.
+   2) Consequence: A private, written warning with a time-limited cooldown period designed to underscore the seriousness of the situation and give the community members involved time to process the incident. The cooldown period may be limited to particular communication channels or interactions with particular community members.
+   3) Repair: Examples of repair may include making an apology, using the cooldown period to reflect on actions and impact, and being thoughtful about re-entering community spaces after the period is over.
+3) Temporary Suspension
+   1) Event: A pattern of repeated violation which the Community Moderators have tried to address with warnings, or a single serious violation.
+   2) Consequence: A private written warning with conditions for return from suspension. In general, temporary suspensions give the person being suspended time to reflect upon their behavior and possible corrective actions.
+   3) Repair: Examples of repair include respecting the spirit of the suspension, meeting the specified conditions for return, and being thoughtful about how to reintegrate with the community when the suspension is lifted.
+4) Permanent Ban
+   1) Event: A pattern of repeated code of conduct violations that other steps on the ladder have failed to resolve, or a violation so serious that the Community Moderators determine there is no way to keep the community safe with this person as a member.
+   2) Consequence: Access to all community spaces, tools, and communication channels is removed. In general, permanent bans should be rarely used, should have strong reasoning behind them, and should only be resorted to if working through other remedies has failed to change the behavior.
+   3) Repair: There is no possible repair in cases of this severity.
+
+This enforcement ladder is intended as a guideline. It does not limit the ability of Community Managers to use their discretion and judgment, in keeping with the best interests of our community.
+
+
+## Scope
+
+This Code of Conduct applies within all community spaces, and also applies when an individual is officially representing the community in public or other spaces. Examples of representing our community include using an official email address, posting via an official social media account, or acting as an appointed representative at an online or offline event.
+
+

+# Contributing guidelines
+
+## When submitting pull requests
+
+* Explain your thinking in why a change or addition is needed.
+  * Is it a requested change or feature?
+  * If not, open a feature request to get feedback before making a pull request.
+
+* Split up multiple unrelated changes in multiple pull requests.
+
+* If it's a fix for a unreported bug, make a bug report and link the pull request.
+
+* Purely cosmetic changes won't be accepted without a very good explanation of its value.
+
+* Submissions where the majority of the code is AI generated must be marked with [AI generated].
+
+* "Vibe coded" PR's where it seems like the author doesn't understand the generated code will be dismissed.
+
+## Formatting
+
+### Follow the current syntax design
+
+* Indent type: Tabs
+
+* Tab size: 4
+
+* Alternative operators `and`, `or` and `not`.
+
+* Opening curly braces `{` at the end of the same line as the statement/condition.
+
+## General guidelines
+
+* Don't force a programming style. Use object oriented, functional, data oriented, etc., where it's suitable.
+
+* Use [RAII](https://en.cppreference.com/w/cpp/language/raii).
+
+* Make use of the standard algorithms library, watch [C++ Seasoning](https://www.youtube.com/watch?v=W2tWOdzgXHA) and [105 STL Algorithms](https://www.youtube.com/watch?v=bFSnXNIsK4A) for inspiration.
+
+* Use the included `fmt` library for string formatting, see issue [#535](https://github.com/aristocratos/btop/issues/535) for more info and examples.
+
+* Do not add includes if the same functionality can be achieved using the already included libraries.
+
+* Use descriptive names for variables.
+
+* Use comments if not very obvious what your code is doing.
+
+* Add comments as labels for what's currently happening in bigger sections of code for better readability.
+
+* Avoid writing to disk.
+
+* If using the logger functions, be sensible, only call it if something of importance has changed.
+
+* Benchmark your code and look for alternatives if they cause a noticeable negative impact.
+
+For questions open a new discussion thread or send a mail to jakob@qvantnet.com
+
+For proposing changes to this document create a [new issue](https://github.com/aristocratos/btop/issues/new/choose).

+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed

+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions

+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.

+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,

+## News
+
+##### 4 December 2025
+
+Since there is a increasing amount of AI generated/assisted PR's, the following guidlines have been added to CONTRIBUTING.md:
+
+* Submissions where the majority of the code is AI generated must be marked with [AI generated].
+
+* "Vibe coded" PR's where it seems like the author doesn't understand the generated code will be dismissed.
+
+##### 22 September 2024
+
+Btop release v1.4.0
+
+Intel GPU support added, note that only GPU utilization, power usage and clock speed available to monitor. Thanks to [@bjia56](https://github.com/bjia56) for contributions.
+
+NetBSD support added. Thanks to [@fraggerfox](https://github.com/fraggerfox) for contributions.
+
+See [CHANGELOG.md](CHANGELOG.md) and latest [release](https://github.com/aristocratos/btop/releases/latest) for detailed list of new features, bug fixes and new themes.
+
+##### 7 January 2024
+
+Btop release v1.3.0
+
+Big release with GPU support added for Linux and platform support for OpenBSD. Big thanks to [@romner-set](https://github.com/romner-set) (GPU support) and [@joske](https://github.com/joske) (OpenBSD support) for contributions.
+And a multitude of bugfixes and small changes, see [CHANGELOG.md](CHANGELOG.md) and latest [release](https://github.com/aristocratos/btop/releases/latest) for detailed list and attributions.
+
+See news entry below for more information regarding GPU support.
+
+##### 25 November 2023
+
+GPU monitoring added for Linux!
+
+Compile from git main to try it out.
+
+Use keys `5`, `6`, `7` and `0` to show/hide the gpu monitoring boxes. `5` = Gpu 1, `6` = Gpu 2, etc.
+
+Gpu stats/graphs can also be displayed in the "Cpu box" (not as verbose), see the cpu options menu for info and configuration.
+
+Note that the binaries provided on the release page (when released) and the continuous builds will not have gpu support enabled.
+
+Because the GPU support relies on loading of dynamic gpu libraries, gpu support will not work when also static linking.
+
+See [Compilation Linux](#compilation-linux) for more info on how to compile with gpu monitoring support.
+
+Many thanks to [@romner-set](https://github.com/romner-set) who wrote the vast majority of the implementation for GPU support.
+
+Big update with version bump to 1.3 coming soon.
+
+##### 28 August 2022
+
+[![btop4win](https://github.com/aristocratos/btop4win/raw/master/Img/logo.png)](https://github.com/aristocratos/btop4win)
+
+First release of btop4win available at https://github.com/aristocratos/btop4win
+
+<details>
+<summary>More...</summary>
+
+##### 16 January 2022
+
+Release v1.2.0 with FreeBSD support. No release binaries for FreeBSD provided as of yet.
+
+Again a big thanks to [@joske](https://github.com/joske) for his porting efforts!
+
+Since compatibility with Linux, macOS and FreeBSD are done, the focus going forward will be on new features like GPU monitoring.
+
+##### 13 November 2021
+
+Release v1.1.0 with macOS support. Binaries in [continuous-build-macos](https://github.com/aristocratos/btop/actions/workflows/continuous-build-macos.yml) are only x86 for now.
+macOS binaries + installer are included for both x86 and ARM64 (Apple Silicon) in the releases.
+
+Big thank you to [@joske](https://github.com/joske) who wrote the vast majority of the implementation!
+
+##### 30 October 2021
+
+Work on the OSX [macOS] and FreeBSD branches, both initiated and mostly worked on by [@joske](https://github.com/joske), will likely be completed in the coming weeks.
+The OSX [macOS] branch has some memory leaks that needs to be sorted out and both have some issues with the processes cpu usage calculation and other smaller issues that needs fixing.
+
+If you want to help out, test for bugs/fix bugs or just try out the branches:
+
+**macOS / OSX**
+```bash
+# Install and use Homebrew or MacPorts package managers for easy dependency installation
+brew install coreutils make gcc@11 lowdown
+git clone https://github.com/aristocratos/btop.git
+cd btop
+git checkout OSX
+gmake
+```
+
+**FreeBSD**
+```bash
+sudo pkg install gmake gcc11 coreutils git lowdown
+git clone https://github.com/aristocratos/btop.git
+cd btop
+git checkout freebsd
+gmake
+```
+
+Note that GNU make (`gmake`) is recommended but not required for macOS/OSX but it is required on FreeBSD.
+
+
+##### 6 October 2021
+
+macOS development have been started by [@joske](https://github.com/joske), big thanks :)
+See branch [OSX](https://github.com/aristocratos/btop/tree/OSX) for current progress.
+
+##### 18 September 2021
+
+The Linux version of btop++ is complete. Released as version 1.0.0
+
+I will be providing statically compiled binaries for a range of architectures in every release for those having problems compiling.
+
+For compilation GCC 11 is required.
+
+Please report any bugs to the [Issues](https://github.com/aristocratos/btop/issues/new?assignees=aristocratos&labels=bug&template=bug_report.md&title=%5BBUG%5D) page.
+
+The development plan right now:
+
+* 1.1.0 macOS [OSX] support
+* 1.2.0 FreeBSD support
+* 1.3.0 Support for GPU monitoring
+* 1.X.0 Other platforms and features...
+
+Windows support is not in the plans as of now, but if anyone else wants to take it on, I will try to help.
+
+##### 5 May 2021
+
+This project is gonna take some time until it has complete feature parity with bpytop, since all system information gathering will have to be written from scratch without any external libraries.
+And will need some help in the form of code contributions to get complete support for BSD and macOS/OSX.

+
+**[CHANGELOG.md](CHANGELOG.md)**
+
+**[CONTRIBUTING.md](CONTRIBUTING.md)**
+
+**[CODE_OF_CONDUCT.md](CODE_OF_CONDUCT.md)**
+
+## Description
+
+Resource monitor that shows usage and stats for processor, memory, disks, network and processes.
+
+C++ version and continuation of [bashtop](https://github.com/aristocratos/bashtop) and [bpytop](https://github.com/aristocratos/bpytop).
+
+## Features
+
+* Easy to use, with a game inspired menu system.
+* Full mouse support: all buttons with a highlighted key are clickable and mouse scrolling works in process list and menu boxes.
+* Fast and responsive UI with UP, DOWN key process selection.
+* Function for showing detailed stats for selected process.
+* Ability to filter processes.
+* Easy switching between sorting options.
+* Tree view of processes.
+* Send any signal to selected process.
+* Pause the process list.
+* UI menu for changing all config file options.
+* Auto scaling graph for network usage.
+* Shows IO activity and speeds for disks.
+* Battery meter
+* Selectable symbols for the graphs.
+* Custom presets
+* And more...
+
+## Themes
+
+Btop++ uses the same theme files as bpytop and bashtop (some color values missing in bashtop themes).
+
+See [themes](https://github.com/aristocratos/btop/tree/main/themes) folder for available themes.
+
+Btop searches the following directories for system themes:
+
+* `../share/btop/themes` (this path is relative to the btop executable)
+* `/usr/local/share/btop/themes`
+* `/usr/share/btop/themes`
+
+The first directory that exists and isn't empty is used as the system themes directory.
+
+The user themes directory depends on which environment variables are set:
+
+* If `$XDG_CONFIG_HOME` is set, the user themes directory is `$XDG_CONFIG_HOME/btop/themes`
+* Otherwise, if `$HOME` is set, the user themes directory is `$HOME/.config/btop/themes`
+* Otherwise, the user themes directory is `~/.config/btop/themes`
+
+The `make install` command places the default themes in `[$PREFIX or /usr/local]/share/btop/themes`.

+
+## Prerequisites
+
+For the best experience run within a terminal with support for:
+
+* 24-bit truecolor ([See list of terminals with truecolor support](https://github.com/termstandard/colors))
+* 256-color terminals are supported through 24-bit to 256-color conversion when setting "truecolor" to False in the options or with "-lc/--low-color" arguments.
+* 16 color TTY mode will be activated if a real tty device is detected. Can be forced with "-t/--tty" arguments.
+* Wide characters (Are sometimes problematic in web-based terminals)
+
+Also necessary is a UTF8 locale and a font that includes:
+
+* Unicode Block “Braille Patterns” U+2800 - U+28FF (Not needed in TTY mode or with graphs set to type: block or tty.)
+* Unicode Block “Geometric Shapes” U+25A0 - U+25FF
+* Unicode Block "Box Drawing" and "Block Elements" U+2500 - U+259F
+
+### **Optional Dependencies (Needed for GPU monitoring) (Only Linux)**
+
+GPU monitoring also requires a btop binary built with GPU support (`GPU_SUPPORT=true` flag).
+
+See [GPU compatibility](#gpu-compatibility) section for more about compiling with GPU support.
+
+ * **NVIDIA**
+
+   If you have an NVIDIA GPU you must use an official NVIDIA driver, both the closed-source and open-source ones have been verified to work.
+
+   In addition to that you must also have the nvidia-ml dynamic library installed, which should be included with the driver package of your distribution.
+
+ * **AMD**
+
+   If you have an AMD GPU `rocm_smi_lib` is required, which may or may not be packaged for your distribution.
+
+ * **INTEL**
+
+   Requires a working C compiler if compiling from source.
+
+   Also requires the user to have permission to read from SYSFS.
+
+   Can be set with `make setcap` (preferred) or `make setuid` or by running btop with `sudo` or equivalent.
+
+### **Notice (Text rendering issues)**
+
+* If you are having problems with the characters in the graphs not looking like they do in the screenshots, it's likely a problem with your systems configured fallback font not having support for braille characters.
+
+* See [Terminess Powerline](https://github.com/ryanoasis/nerd-fonts/blob/master/patched-fonts/Terminus/TerminessNerdFontMono-Regular.ttf) for an example of a font that includes the braille symbols.
+
+* See comments by @sgleizes [link](https://github.com/aristocratos/bpytop/issues/100#issuecomment-684036827) and @XenHat [link](https://github.com/aristocratos/bpytop/issues/100#issuecomment-691585587) in issue #100 for possible solutions.
+
+* If text is misaligned and you use Konsole or Yakuake, turning off "Bi-Directional text rendering" is a possible fix.
+
+* Characters clipping into each other or text/border misalignments are not bugs caused by btop, but most likely a fontconfig or terminal problem where the braille characters making up the graphs aren't rendered correctly.
+
+* Look to the creators of the terminal emulator you use to fix these issues if the previously mentioned fixes don't work for you.

+## Installation
+
+**Binaries for Linux are statically compiled with musl and work on kernel releases 2.6.39 and newer**
+
+1. **Download btop-(VERSION)-(ARCH)-(PLATFORM).tbz from [latest release](https://github.com/aristocratos/btop/releases/latest) and unpack to a new folder**
+
+   **Notice! Use x86_64 for 64-bit x86 systems, i486 and i686 are 32-bit!**
+
+2. **Install (from created folder)**
+
+   * **Run:**
+
+   ```bash
+   # use "make install PREFIX=/target/dir" to set target, default: /usr/local
+   # only use "sudo" when installing to a NON user owned directory
+   sudo make install
+   ```
+
+3. **(Optional/Required for Intel GPU and CPU wattage) Set extended capabilities or suid bit to btop**
+
+   Enables signal sending to any process without starting with `sudo` and can prevent /proc read permissions problems on some systems.
+
+   Is required for Intel GPU support and CPU wattage monitoring.
+
+   * **Run:**
+
+   ```bash
+   # run after make install and use same PREFIX if any was used at install
+   sudo make setcap
+   ```
+   * **or**
+
+   ```bash
+   # run after make install and use same PREFIX if any was used at install
+   # set SU_USER and SU_GROUP to select user and group, default is root:root
+   sudo make setuid
+   ```
+
+* **Uninstall**

+   ```
+
+**Binary release (from native os repo)**
+
+* **openSUSE**
+  * **Tumbleweed:**
+    ```bash
+    sudo zypper in btop
+    ```
+  * For all other versions, see [openSUSE Software: btop](https://software.opensuse.org/package/btop)
+* **Fedora**
+    ```bash
+    sudo dnf install btop
+	```

+
+* **[Homebrew](https://formulae.brew.sh/formula/btop)**
+  ```bash
+  brew install btop
+  ```
+
+## Compilation Linux
+
+   Requires at least GCC 14 or Clang 19.
+
+   The Makefile also needs GNU `coreutils` and `sed` (should already be installed on any modern distribution).
+
+   ### GPU compatibility
+
+   Btop++ supports Nvidia and AMD GPUs and Intel IGPUs out of the box on Linux x86_64, provided you have the correct drivers and libraries.
+
+   Gpu support for Nvidia or AMD will not work when static linking glibc (or musl, etc.)!
+
+   For x86_64 Linux the flag `GPU_SUPPORT` is automatically set to `true`, to manually disable gpu support set the flag to false, like:
+
+   `make GPU_SUPPORT=false` (or `cmake -DBTOP_GPU=false` with CMake)
+
+ * **NVIDIA**
+
+    You must use an official NVIDIA driver, both the closed-source and [open-source](https://github.com/NVIDIA/open-gpu-kernel-modules) ones have been verified to work.
+
+    In addition to that you must also have the `nvidia-ml` dynamic library installed, which should be included with the driver package of your distribution.
+
+ * **AMD**
+
+    AMDGPU data is queried using the [ROCm SMI](https://github.com/rocm/rocm_smi_lib) library, which may or may not be packaged for your distribution. If your distribution doesn't provide a package, btop++ is statically linked to ROCm SMI with the `RSMI_STATIC=true` make flag.
+
+    This flag expects the ROCm SMI source code in `lib/rocm_smi_lib`, and compilation will fail if it's not there. The latest tested version is 5.6.x, which can be obtained with the following command:
+
+   ```bash
+   git clone https://github.com/rocm/rocm_smi_lib.git --depth 1 -b rocm-5.6.x lib/rocm_smi_lib
+   ```

+  // bit is impossible in that case, because 00 (unset color) means the
+  // 24 bits that precede the discriminator are all zero.

+**btop** is a program that shows usage and stats for processor, memory, disks, network, and processes.
+
+# OPTIONS
+
+The program follows the usual GNU command line syntax, with long options
+starting with two dashes ('-'). A summary of options is included below.
+
+**-c**, **\-\-config _file_**
+:   Path to a config file.
+
+**-d**, **\-\-debug**
+:   Start in debug mode with additional logs and metrics.
+
+**-f**, **\-\-filter _filter_**
+:   Set an initial process filter.
+
+**\-\-force-utf**
+:   Force start even if no UTF-8 locale was detected.
+
+**-l**, **\-\-low-color**
+:   Disable true color, 256 colors only.
+
+**-p**, **\-\-preset _id_**
+:   Start with a preset (0-9).
+
+**-t**, **\-\-tty-on**
+:   Force tty mode with ANSI graph symbols and 16 colors only.
+
+**\-\-tty-off**
+:   Force disable tty mode.
+
+**\-\-themes-dir _dir_**
+:   Path to a custom themes directory. When specified, this directory takes priority over the default theme search paths.
+
+**-u**, **\-\-update _ms_**
+:   Set an initial update rate in milliseconds.
+
+**-h**, **\-\-help**
+:   Show summary of options.
+
+**-V**, **\-\-version**
+:   Show version of program.

+/**
+ * struct drm_mode_fb_cmd2 - Frame-buffer metadata.
+ *
+ * This struct holds frame-buffer metadata. There are two ways to use it:
+ *
+ * - User-space can fill this struct and perform a &DRM_IOCTL_MODE_ADDFB2
+ *   ioctl to register a new frame-buffer. The new frame-buffer object ID will
+ *   be set by the kernel in @fb_id.
+ * - User-space can set @fb_id and perform a &DRM_IOCTL_MODE_GETFB2 ioctl to
+ *   fetch metadata about an existing frame-buffer.
+ *
+ * In case of planar formats, this struct allows up to 4 buffer objects with
+ * offsets and pitches per plane. The pitch and offset order are dictated by
+ * the format FourCC as defined by ``drm_fourcc.h``, e.g. NV12 is described as:
+ *
+ *     YUV 4:2:0 image with a plane of 8-bit Y samples followed by an
+ *     interleaved U/V plane containing 8-bit 2x2 subsampled colour difference
+ *     samples.
+ *
+ * So it would consist of a Y plane at ``offsets[0]`` and a UV plane at
+ * ``offsets[1]``.
+ *
+ * To accommodate tiled, compressed, etc formats, a modifier can be specified.
+ * For more information see the "Format Modifiers" section. Note that even
+ * though it looks like we have a modifier per-plane, we in fact do not. The
+ * modifier for each plane must be identical. Thus all combinations of
+ * different data layouts for multi-plane formats must be enumerated as
+ * separate modifiers.
+ *
+ * All of the entries in @handles, @pitches, @offsets and @modifier must be
+ * zero when unused. Warning, for @offsets and @modifier zero can't be used to
+ * figure out whether the entry is used or not since it's a valid value (a zero
+ * offset is common, and a zero modifier is &DRM_FORMAT_MOD_LINEAR).

+/**
+ * struct i915_user_extension - Base class for defining a chain of extensions
+ *
+ * Many interfaces need to grow over time. In most cases we can simply
+ * extend the struct and have userspace pass in more data. Another option,
+ * as demonstrated by Vulkan's approach to providing extensions for forward
+ * and backward compatibility, is to use a list of optional structs to
+ * provide those extra details.
+ *
+ * The key advantage to using an extension chain is that it allows us to
+ * redefine the interface more easily than an ever growing struct of
+ * increasing complexity, and for large parts of that interface to be
+ * entirely optional. The downside is more pointer chasing; chasing across
+ * the boundary with pointers encapsulated inside u64.
+ *
+ * Example chaining:
+ *
+ * .. code-block:: C
+ *
+ *	struct i915_user_extension ext3 {
+ *		.next_extension = 0, // end
+ *		.name = ...,
+ *	};
+ *	struct i915_user_extension ext2 {
+ *		.next_extension = (uintptr_t)&ext3,
+ *		.name = ...,
+ *	};
+ *	struct i915_user_extension ext1 {
+ *		.next_extension = (uintptr_t)&ext2,
+ *		.name = ...,
+ *	};
+ *
+ * Typically the struct i915_user_extension would be embedded in some uAPI
+ * struct, and in this case we would feed it the head of the chain(i.e ext1),
+ * which would then apply all of the above extensions.
+ *

+ * Allow userspace to control the GTT caching bits for a given object when the
+ * object is later mapped through the ppGTT(or GGTT on older platforms lacking
+ * ppGTT support, or if the object is used for scanout). Note that this might
+ * require unbinding the object from the GTT first, if its current caching value
+ * doesn't match.
+ *
+ * Note that this all changes on discrete platforms, starting from DG1, the
+ * set/get caching is no longer supported, and is now rejected.  Instead the CPU
+ * caching attributes(WB vs WC) will become an immutable creation time property
+ * for the object, along with the GTT caching level. For now we don't expose any
+ * new uAPI for this, instead on DG1 this is all implicit, although this largely
+ * shouldn't matter since DG1 is coherent by default(without any way of
+ * controlling it).
+ *
+ * Implicit caching rules, starting from DG1:
+ *
+ *     - If any of the object placements (see &drm_i915_gem_create_ext_memory_regions)
+ *       contain I915_MEMORY_CLASS_DEVICE then the object will be allocated and
+ *       mapped as write-combined only.
+ *
+ *     - Everything else is always allocated and mapped as write-back, with the
+ *       guarantee that everything is also coherent with the GPU.
+ *
+ * Note that this is likely to change in the future again, where we might need
+ * more flexibility on future devices, so making this all explicit as part of a
+ * new &drm_i915_gem_create_ext extension is probable.
+ *
+ * Side note: Part of the reason for this is that changing the at-allocation-time CPU
+ * caching attributes for the pages might be required(and is expensive) if we
+ * need to then CPU map the pages later with different caching attributes. This
+ * inconsistent caching behaviour, while supported on x86, is not universally
+ * supported on other architectures. So for simplicity we opt for setting
+ * everything at creation time, whilst also making it immutable, on discrete
+ * platforms.

+ * DOC: Virtual Engine uAPI
+ *
+ * Virtual engine is a concept where userspace is able to configure a set of
+ * physical engines, submit a batch buffer, and let the driver execute it on any
+ * engine from the set as it sees fit.
+ *
+ * This is primarily useful on parts which have multiple instances of a same
+ * class engine, like for example GT3+ Skylake parts with their two VCS engines.
+ *
+ * For instance userspace can enumerate all engines of a certain class using the
+ * previously described `Engine Discovery uAPI`_. After that userspace can
+ * create a GEM context with a placeholder slot for the virtual engine (using
+ * `I915_ENGINE_CLASS_INVALID` and `I915_ENGINE_CLASS_INVALID_NONE` for class
+ * and instance respectively) and finally using the
+ * `I915_CONTEXT_ENGINES_EXT_LOAD_BALANCE` extension place a virtual engine in
+ * the same reserved slot.
+ *
+ * Example of creating a virtual engine and submitting a batch buffer to it:
+ *
+ * .. code-block:: C
+ *
+ * 	I915_DEFINE_CONTEXT_ENGINES_LOAD_BALANCE(virtual, 2) = {

+ * struct i915_context_engines_parallel_submit - Configure engine for
+ * parallel submission.
+ *
+ * Setup a slot in the context engine map to allow multiple BBs to be submitted
+ * in a single execbuf IOCTL. Those BBs will then be scheduled to run on the GPU
+ * in parallel. Multiple hardware contexts are created internally in the i915 to
+ * run these BBs. Once a slot is configured for N BBs only N BBs can be
+ * submitted in each execbuf IOCTL and this is implicit behavior e.g. The user
+ * doesn't tell the execbuf IOCTL there are N BBs, the execbuf IOCTL knows how
+ * many BBs there are based on the slot's configuration. The N BBs are the last
+ * N buffer objects or first N if I915_EXEC_BATCH_FIRST is set.
+ *
+ * The default placement behavior is to create implicit bonds between each
+ * context if each context maps to more than 1 physical engine (e.g. context is
+ * a virtual engine). Also we only allow contexts of same engine class and these
+ * contexts must be in logically contiguous order. Examples of the placement
+ * behavior are described below. Lastly, the default is to not allow BBs to be
+ * preempted mid-batch. Rather insert coordinated preemption points on all
+ * hardware contexts between each set of BBs. Flags could be added in the future
+ * to change both of these default behaviors.
+ *
+ * Returns -EINVAL if hardware context placement configuration is invalid or if
+ * the placement configuration isn't supported on the platform / submission
+ * interface.
+ * Returns -ENODEV if extension isn't supported on the platform / submission
+ * interface.

+ *
+ * To use it created GEM contexts need to be configured with a list of engines

+ * DOC: Engine Discovery uAPI
+ *
+ * Engine discovery uAPI is a way of enumerating physical engines present in a
+ * GPU associated with an open i915 DRM file descriptor. This supersedes the old
+ * way of using `DRM_IOCTL_I915_GETPARAM` and engine identifiers like
+ * `I915_PARAM_HAS_BLT`.
+ *
+ * The need for this interface came starting with Icelake and newer GPUs, which
+ * started to establish a pattern of having multiple engines of a same class,
+ * where not all instances were always completely functionally equivalent.
+ *
+ * Entry point for this uapi is `DRM_IOCTL_I915_QUERY` with the
+ * `DRM_I915_QUERY_ENGINE_INFO` as the queried item id.
+ *
+ * Example for getting the list of engines:
+ *
+ * .. code-block:: C
+ *
+ * 	struct drm_i915_query_engine_info *info;
+ * 	struct drm_i915_query_item item = {
+ * 		.query_id = DRM_I915_QUERY_ENGINE_INFO;

+ * 	// First query the size of the blob we need, this needs to be large
+ * 	// enough to hold our array of engines. The kernel will fill out the
+ * 	// item.length for us, which is the number of bytes we need.
+ * 	//
+ *	// Alternatively a large buffer can be allocated straightaway enabling
+ * 	// querying in one pass, in which case item.length should contain the
+ * 	// length of the provided buffer.

+ * 	}
+ *
+ * 	free(info);
+ *
+ * Each of the enumerated engines, apart from being defined by its class and
+ * instance (see `struct i915_engine_class_instance`), also can have flags and

+ *
