+# 重构 AxVCpu
+
+## 1. 背景与动机
+
+当前 axvisor 项目包含三个核心 crate：
+- axvisor：顶层虚拟化与平台管理逻辑
+- axvm：虚拟机（VMM / guest execution）相关实现
+- axdevice：虚拟/直通设备抽象与注册
+
+随着对多架构（如 RISC-V、AArch64、x86_64 等）与多平台（不同 SoC / 板级）的支持增加，项目内部出现以下问题：
+1. arch 相关条件编译（`#[cfg(...)]`）在 axvm 与 axdevice 中大量散落，难以维护。
+2. 配置项（arch、平台、虚拟设备开关、内存/核数限制等）分布于：
+   - axvm（如启动参数、MMU/内存模型）
+   - axdevice（设备选择、初始化）
+   - axvmconfig / axvisor_api（跨 crate 传递结构）
+   造成信息路径割裂。
+3. 配置“流向”不清晰：谁定义 / 谁持有 / 谁消费不明确。
+4. 架构耦合阻碍复用：axvm、axdevice 难以在其他宿主或测试环境中独立使用（例如单元测试 / 模拟）。
+5. 虚拟设备在axdevice直接注册，造成配置需经过axvisor->axvm->axdevice，跨多个crate，重复传递。
+6. 架构感知逻辑与“功能逻辑”耦合，增加新增架构或改动现有策略的风险与成本。
+7. API接口不统一，同一个库中同时使用多种不同的接口风格，包括trait直接作为接口、axvisor-api外部函数和extern "C"函数。
+8. axvcpu本意是设计为抹除架构间vcpu差异，但实际是各架构差异较大，在这一层抹除差异造成接口过度复杂，无法根据特性优化。
+**vCPU核心功能差异：**
+
+| 功能特性 | ARM64 | x86_64 | RISC-V | 抽象复杂度 |
+|---------|-------|--------|--------|-----------|
+| **虚拟化扩展** | VHE/VNCR | VMX | H-extension | ⭐⭐⭐ |
+| **上下文切换** | EL2/EL1切换 | VMCS管理 | HSTATE管理 | ⭐⭐⭐ |
+| **异常处理** | Syndrome解析 | Exit Reason | Exit Cause | ⭐⭐ |
+| **内存管理** | Stage-2页表 | EPT/NPT | Sv-39页表 | ⭐⭐⭐ |
+| **寄存器模型** | 通用+系统寄存器 | 通用+MSR | 通用+CSR | ⭐⭐ |
+
+**虚拟中断控制器差异对比：**
+
+| 特性 | ARM vGIC | Intel APIC | RISC-V IMSIC | 接口统一难度 |
+|------|----------|------------|--------------|-------------|
+| **消息传递** | SGI/ID/PPI | LAPIC/IOAPIC | MSI | ⭐⭐⭐⭐⭐ |
+| **路由机制** | Affinity/Target | Fixed/Lowest | AIA | ⭐⭐⭐⭐ |
+| **优先级** | 32级优先级 | 8级优先级 | 配置优先级 | ⭐⭐⭐ |
+| **虚拟化支持** | vGICv2/vGICv3 | APICv | IMSIC+HVIP | ⭐⭐⭐⭐⭐ |
+| **配置接口** | Distributor | MSR访问 | MMIO访问 | ⭐⭐⭐⭐ |

+
+
+## 2. 目标
+
+| 目标类别 | 目标描述 | 衡量指标 |
+|----------|----------|----------|
+| 架构解耦 | axvm、axdevice 不再直接包含 arch 特定条件编译 | arch 条件编译迁移到 axvisor |
+| 配置集中 | 所有外部可调配置集中在 axvisor | 单一入口（Configuration Root） |
+| 接口稳定 | axvm / axdevice 通过清晰 API 接收已解析配置 | API 文档化，函数/类型变更频率降低 |
+| 可测试性 | 可在无真实硬件 / 无特定 arch 条件下运行核心逻辑测试 | CI 引入“generic host” profile |
+| 可扩展性 | 支持新增 arch / 虚拟设备时最小化侵入 | 新增 arch 时仅修改 axvisor 层及少量 adapter |
+
+## 3. 优化方案
+
+![new-architecture](layout.svg)
+
+新的设计理念：从"vCPU层抹除差异"转变为"VM层抹除差异，vCPU求同存异"。核心相似功能抽象，架构特性独立，最小公约的函数组合，最终在VM层抹除架构差异
+
+### 单一配置源（Single Source of Truth）
+
+所有运行参数（arch、平台、设备编排、资源限制等）在 axvisor 中构建并冻结。
+
+### Arch 隔离, 模块化设计
+
+配置只“下行”到 axvm、axdevice；运行期状态可“上行”以供监控。
+
+循环依赖（crate-interface）被限制在 `axplat <-> axplat-dyn` 最小范围内。
+
+对 `arceos` 的依赖仅包括 `std` 兼容部分，以此使 `AxVisor` 本体和所有组件做到 OS 无关，后续可方便支持其他单内核甚至宏内核，微内核等不同宿主环境。
+
+`Arch` 专属代码集中于 `axvm::arch::*`。对于 `Arch` 相关的功能，通过 `axplat-dyn` 透传 `somehal` 的 `Arch` 实现，使得 `Arch` 相关功能限制在 `AxVm` 内部，避免其他组件产生对 `Arch` 的依赖。
+
+`common` 提供跨架构通用逻辑、模块与接口定义。
+
+每个架构实现其特定的 VCPU、内存模型、中断注入等，组合`common`中的模块，如 `device`、`addrspace` 等。最终通过 `trait ArchVm` 适配器暴露统一接口供上层调用。从而实现增加或修改某个架构时不影响其他架构。
+
+### 通过状态机管理虚拟机生命周期与资源分配
+
+- `AxVisor` 内核维护 `vmm` 容器，承载多个 `Vm` 实例。
+- `VmData` 记录基础信息（ID、Name）与状态机 `VmMachineState`。
+- `VmMachineState` 为枚举，涵盖状态数据：
+
+```rust
+pub enum VmMachineState {
+    Uninit(VmMachineUninit),
+    Inited(VmMachineInited),
+    Running(VmMachineRunning),
+    Switching,
+    #[allow(unused)]
+    Stopping(VmStatusStopping),
+    Stopped,
+}
+```
+
+确保不混淆相应状态的数据与行为。状态转换通过 `Switching` 中间态进行，用 `Switching` 换出前一状态，使数据所有权可以 `move` 到下一状态。

+# AxVisor 架构继续分析
+
+## 原有架构
+
+![old](old.svg)
+
+1. 虚拟机需要大量 Arch 特定的虚拟化支持，而 axhal 统一了各 arch 接口，抹除了 arch 差异，导致每需要一个功能，都需要在 axhal 中添加对应 arch 的实现，而其他 arch 则需要添加空实现，增加了维护成本。
+
+2. 同样的，axvcpu 也统一了 各 arch 的 vcpu 接口，导致每增加一个 vcpu 功能，都需要在 axvcpu 中添加对应 arch 的实现，增加了维护成本。
+
+3. 全部组件依赖 `axvisor-api`, 任何组件想要使用其他组件的功能，都需要通过 `axvisor-api` 进行间接调用，而 arch 开发中，会增加 arch 相关的特有函数，这又需要在 axvcpu 或 axhal 中增加其他 arch 空实现，并修改 `axvisor-api`，进一步增加了 `axvisor-api` 修改的可能性，导致几乎任何修改，都需要修改 `axvisor-api`、`axhal`， 而修改 `axvisor-api`, `axhal`，则会导致修改所有依赖库，进而引发修改所有 `axplat` 等等几乎所有组件。
+
+## 重构后
+
+![new](refactor.svg)
+
+1. 将所有架构相关（arch-specific）的实现收敛到 AxVm 模块：由 AxVm 统一负责虚拟机生命周期管理，并对外提供一致的虚拟机管理接口。AxVm 内部按架构选择对应的 VCPU 实现与地址空间实现，避免 arch-specific 代码分散在各个模块中。各架构的 VM 也不再通过 axvcpu 抹平差异，而是直接调用 arch_vcpu；由 arch_vcpu 以各自方式实现/适配 axvcpu 的能力，从而复用通用逻辑，并允许每个 ArchVm 以自己的方式组合 vcpu、vdevice、addrspace 等组件。
+
+2. `axvisor-api` 改动：各模块不再直接依赖 `axvisor-api`，而是各自暴露最小必要接口，降低模块变更引发的全局联动修改。
+
+3. 对 ArceOS 的依赖：行为上仅依赖 `std` 部分；虚拟化相关的特有能力通过 crate-interface 或直接依赖 HAL 层实现，尽量避免对 ArceOS 做侵入式修改。
+
+## 深化设计axvm
+
+![axvm](refactor-vm.svg)
+
+### AxVm 内部设计
+
+如图所示，`AxVm` 通过状态机管理虚拟机生命周期与资源分配。
+
+1. **整体结构**：
+
+ - `AxVisor` 内核维护 `vms` 容器，承载多个 `Vm` 实例。
+ - `Vm` 持有静态配置（`image_loader`, `fdt`）以及共享的运行时数据 `VmData`（`Arc` 管理）。
+
+2. **状态管理 (`VmData`)**
+
+ - `VmData` 记录基础信息（ID、Name）与核心状态 `status: RWLock<VmMachine>`。
+ - `VmMachine` 为枚举，涵盖三种状态数据：
+   - **InitData**：配置、`vcpus: Vec<VCpu>`、`addrspace: Mutex<>`，启动前的准备态。
+   - **VmRunData**：`start()` 时将 `addrspace` 等从 InitData `move` 进来，初始化 `v-device-manager: Mutex<>`，提供 `stop()`, `suspend()`, `is_running()` 运行时接口。
+   - **StoppedData**：停止后保留统计信息 `statistic ...`。
+
+3. **VCPU 与线程模型**
+
+ - `VCpu` 同时包含架构相关 `arch-vcpu` 与通用 `axvcpu` 部分，持有指向 `VmData` 的 `Weak`，避免循环引用。
+ - 进入运行态后，为每个 vcpu 创建线程（Thread1/Thread2...），执行 `loop fn run()`；退出时走 `Stop(drop)` 路径释放资源。
+
+通过在状态间显式迁移资源（Move）并结合 `Arc/Weak` 引用控制，AxVm 将不同阶段的能力与数据隔离，降低跨模块耦合并确保生命周期安全。
