Implement Vulkan device lost recovery
Detect VK_ERROR_DEVICE_LOST (-4) in vkAcquireNextImageKHR, vkQueueSubmit and vkQueuePresentKHR and mark m_deviceLost. Add handleDeviceLost() and recreateDevice() to stop the render timer, cleanup and rebuild surface, logical device, swapchain, command objects, sync objects and VulkanRenderer, then restart rendering on success. Add DEVICE_LOST_RECOVERY.md with recovery docs and remove the obsolete REFACTORING_SUMMARY.md

# ScreenLockDetector 重构总结
|
||||
|
||||
## 重构完成时间
|
||||
2024年11月
|
||||
|
||||
## 重构目标
|
||||
使用公共抽象类重构 ScreenLockDetector，按 Linux 和 MacOS 分别构建子类，实现更好的面向对象设计。
|
||||
|
||||
## 重构成果
|
||||
|

||||
- `screenlockdetector_base.h` - 定义跨平台公共接口
|
||||
- `screenlockdetector_base.cpp` - 实现公共逻辑（状态管理、信号发射）
|
||||
|
||||
2. **Linux 平台实现**
|
||||
- `screenlockdetector_linux.h` - Linux 子类头文件

|
||||
- `ScreenLockDetector` 为客户端提供简单统一的接口
|
||||
- 隐藏内部平台检测的复杂性
|
||||
|
||||
## 主要优势

|
||||
2. 提供插件机制，允许第三方扩展
|
||||
3. 创建独立的 SDK 包
|
||||
|
||||
## SOLID 原则遵循
|
||||
|
||||
- ✅ **单一职责原则** (SRP): 每个类只负责一个平台
|
||||
- ✅ **开闭原则** (OCP): 对扩展开放，对修改关闭
|
||||
- ✅ **里氏替换原则** (LSP): 子类可替换基类使用
|
||||
- ✅ **接口隔离原则** (ISP): 客户端只依赖需要的接口
|
||||
- ✅ **依赖倒置原则** (DIP): 依赖抽象而非具体实现
|
||||
|
||||
## 总结
|
||||
|
||||
这次重构成功地将 ScreenLockDetector 从一个包含大量条件编译的单一类，转换为一个清晰的面向对象架构。新架构不仅保持了完全的向后兼容性，还大大提高了代码的可维护性、可测试性和可扩展性。

# Vulkan 设备丢失恢复机制
|
||||
|
||||
## 问题描述
|
||||
|
||||
当系统从休眠/睡眠状态唤醒时，Vulkan 渲染会失败并报错：
|
||||
|
||||
```
|
||||
Failed to submit draw command buffer! Error code = -4
|
||||
```
|
||||
|
||||
错误码 `-4` 对应 `VK_ERROR_DEVICE_LOST`，表示 Vulkan 逻辑设备已丢失。这是因为：
|
||||
|
||||
1. 系统休眠时 GPU 驱动会被挂起或重置
|
||||
2. 唤醒后 GPU 物理设备重新初始化
|
||||
3. 之前创建的 Vulkan 逻辑设备和资源变为无效状态
|
||||
4. 任何 Vulkan 命令调用都会返回 `VK_ERROR_DEVICE_LOST`
|
||||
|
||||
## 解决方案
|
||||
|
||||
实现了一个完整的设备丢失检测和恢复机制，包括以下几个关键步骤：
|
||||
|
||||
### 1. 添加设备丢失状态标志
|
||||
|
||||
在 `VulkanWidget` 类中添加了 `m_deviceLost` 布尔标志来跟踪设备状态：
|
||||
|
||||
```cpp
|
||||
bool m_deviceLost; // 标记设备是否丢失（如休眠后唤醒）
|
||||
```
|
||||
|
||||
### 2. 在关键 Vulkan 调用点检测设备丢失
|
||||
|
||||
在三个可能返回 `VK_ERROR_DEVICE_LOST` 的关键位置添加了检测：
|
||||
|
||||
#### a) `vkAcquireNextImageKHR` - 获取交换链图像
|
||||
```cpp
|
||||
VkResult result = vkAcquireNextImageKHR(...);
|
||||
if (result == VK_ERROR_DEVICE_LOST || result == -4) {
|
||||
qDebug() << "VK_ERROR_DEVICE_LOST detected in vkAcquireNextImageKHR!";
|
||||
m_deviceLost = true;
|
||||
if (handleDeviceLost()) {
|
||||
qDebug() << "Device recovery successful";
|
||||
} else {
|
||||
qDebug() << "Device recovery failed!";
|
||||
setError("Failed to recover from device lost error");
|
||||
}
|
||||
return;
|
||||
}
|
||||
```
|
||||
|
||||
#### b) `vkQueueSubmit` - 提交命令缓冲
|
||||
```cpp
|
||||
result = vkQueueSubmit(m_queue, 1, &submitInfo, m_inFlightFences[m_currentFrame]);
|
||||
if (result != VK_SUCCESS) {
|
||||
if (result == VK_ERROR_DEVICE_LOST || result == -4) {
|
||||
qDebug() << "VK_ERROR_DEVICE_LOST detected! Attempting to recover device...";
|
||||
m_deviceLost = true;
|
||||
if (handleDeviceLost()) {
|
||||
qDebug() << "Device recovery successful";
|
||||
} else {
|
||||
qDebug() << "Device recovery failed!";
|
||||
setError("Failed to recover from device lost error");
|
||||
}
|
||||
}
|
||||
return;
|
||||
}
|
||||
```
|
||||
|
||||
#### c) `vkQueuePresentKHR` - 呈现图像
|
||||
```cpp
|
||||
result = vkQueuePresentKHR(m_queue, &presentInfo);
|
||||
if (result == VK_ERROR_DEVICE_LOST || result == -4) {
|
||||
qDebug() << "VK_ERROR_DEVICE_LOST detected in vkQueuePresentKHR!";
|
||||
m_deviceLost = true;
|
||||
if (handleDeviceLost()) {
|
||||
qDebug() << "Device recovery successful";
|
||||
} else {
|
||||
qDebug() << "Device recovery failed!";
|
||||
setError("Failed to recover from device lost error");
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 3. 实现设备恢复函数
|
||||
|
||||
#### `handleDeviceLost()` - 设备丢失处理函数
|
||||
|
||||
```cpp
|
||||
bool VulkanWidget::handleDeviceLost()
|
||||
{
|
||||
qDebug() << "=== Handling device lost error ===";
|
||||
|
||||
// 1. 停止渲染定时器，防止在恢复期间继续渲染
|
||||
if (m_renderTimer && m_renderTimer->isActive()) {
|
||||
m_renderTimer->stop();
|
||||
}
|
||||
|
||||
// 2. 等待设备空闲（可能会失败，但仍然尝试）
|
||||
if (m_device != VK_NULL_HANDLE) {
|
||||
vkDeviceWaitIdle(m_device);
|
||||
}
|
||||
|
||||
// 3. 重新创建设备和所有资源
|
||||
bool success = recreateDevice();
|
||||
|
||||
if (success) {
|
||||
m_deviceLost = false;
|
||||
|
||||
// 4. 如果渲染已启用，重新启动定时器
|
||||
if (m_renderingEnabled && m_renderTimer && !m_renderTimer->isActive()) {
|
||||
m_renderTimer->start(16); // ~60 FPS
|
||||
}
|
||||
}
|
||||
|
||||
return success;
|
||||
}
|
||||
```
|
||||
|
||||
#### `recreateDevice()` - 设备重建函数
|
||||
|
||||
完整的资源重建流程：
|
||||
|
||||
```cpp
|
||||
bool VulkanWidget::recreateDevice()
|
||||
{
|
||||
// 1. 清理 VulkanRenderer
|
||||
if (m_renderer) {
|
||||
delete m_renderer;
|
||||
m_renderer = nullptr;
|
||||
}
|
||||
|
||||
// 2. 清理同步对象（Semaphores、Fences）
|
||||
for (size_t i = 0; i < MAX_FRAMES_IN_FLIGHT; i++) {
|
||||
vkDestroySemaphore(m_device, m_renderFinishedSemaphores[i], nullptr);
|
||||
vkDestroySemaphore(m_device, m_imageAvailableSemaphores[i], nullptr);
|
||||
vkDestroyFence(m_device, m_inFlightFences[i], nullptr);
|
||||
}
|
||||
|
||||
// 3. 清理命令对象（Command Pool 和 Command Buffers）
|
||||
vkFreeCommandBuffers(m_device, m_commandPool, ...);
|
||||
vkDestroyCommandPool(m_device, m_commandPool, nullptr);
|
||||
|
||||
// 4. 清理交换链（Swapchain 和相关资源）
|
||||
cleanupSwapchain();
|
||||
|
||||
// 5. 销毁逻辑设备
|
||||
vkDestroyDevice(m_device, nullptr);
|
||||
|
||||
// 6. 销毁 Surface
|
||||
vkDestroySurfaceKHR(m_instance, m_surface, nullptr);
|
||||
|
||||
// === 重建阶段 ===
|
||||
|
||||
// 7. 重新创建 Surface
|
||||
if (!createSurface()) return false;
|
||||
|
||||
// 8. 重新创建逻辑设备
|
||||
if (!createDevice()) return false;
|
||||
|
||||
// 9. 重新创建交换链
|
||||
if (!createSwapchain()) return false;
|
||||
|
||||
// 10. 重新创建命令对象
|
||||
if (!createCommandObjects()) return false;
|
||||
|
||||
// 11. 重新创建同步对象
|
||||
if (!createSyncObjects()) return false;
|
||||
|
||||
// 12. 重新创建 VulkanRenderer
|
||||
m_renderer = new VulkanRenderer();
|
||||
if (!m_renderer->initialize(...)) {
|
||||
delete m_renderer;
|
||||
m_renderer = nullptr;
|
||||
return false;
|
||||
}
|
||||
|
||||
// 13. 重置帧计数器
|
||||
m_currentFrame = 0;
|
||||
|
||||
return true;
|
||||
}
|
||||
```
|
||||
|
||||
### 4. 在渲染启用时主动检查
|
||||
|
||||
在 `setRenderingEnabled(true)` 时主动检查设备是否丢失：
|
||||
|
||||
```cpp
|
||||
void VulkanWidget::setRenderingEnabled(bool enabled)
|
||||
{
|
||||
if (m_renderingEnabled) {
|
||||
// 检查设备是否丢失（例如从睡眠中唤醒后）
|
||||
if (m_deviceLost) {
|
||||
qDebug() << "Device lost detected on resume, attempting recovery...";
|
||||
if (!handleDeviceLost()) {
|
||||
qDebug() << "Failed to recover device, rendering cannot resume";
|
||||
m_renderingEnabled = false;
|
||||
return;
|
||||
}
|
||||
}
|
||||
|
||||
// 启动渲染定时器
|
||||
if (!m_renderTimer->isActive()) {
|
||||
m_renderTimer->start(16);
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 5. 渲染前防护检查
|
||||
|
||||
在 `renderFrame()` 开始时添加保护检查：
|
||||
|
||||
```cpp
|
||||
void VulkanWidget::renderFrame()
|
||||
{
|
||||
// 如果设备丢失，不进行渲染
|
||||
if (m_deviceLost) {
|
||||
return;
|
||||
}
|
||||
|
||||
// 正常渲染流程...
|
||||
}
|
||||
```
|
||||
|
||||
## 工作流程
|
||||
|
||||
### 正常流程
|
||||
1. 用户锁定屏幕 → 停止动画，渲染一帧锁屏画面
|
||||
2. 系统进入休眠/睡眠
|
||||
3. 系统唤醒 → 触发 `aboutToWakeUp` 信号
|
||||
4. 调用 `setRenderingEnabled(true)`
|
||||
5. 检测到 `m_deviceLost == false`，正常恢复渲染
|
||||
|
||||
### 设备丢失恢复流程
|
||||
1. 用户锁定屏幕 → 停止动画
|
||||
2. 系统进入休眠/睡眠 → **GPU 驱动重置，设备丢失**
|
||||
3. 系统唤醒 → 触发 `aboutToWakeUp` 信号
|
||||
4. 调用 `setRenderingEnabled(true)`
|
||||
5. 检测到 `m_deviceLost == true`（或首次渲染时检测到）
|
||||
6. 调用 `handleDeviceLost()`
|
||||
7. 执行 `recreateDevice()` 重建所有 Vulkan 资源
|
||||
8. 设置 `m_deviceLost = false`
|
||||
9. 恢复正常渲染
|
||||
|
||||
### 渲染时设备丢失流程
|
||||
1. 正在渲染中
|
||||
2. 调用 `vkQueueSubmit` 返回 `VK_ERROR_DEVICE_LOST`
|
||||
3. 检测到错误，设置 `m_deviceLost = true`
|
||||
4. 调用 `handleDeviceLost()` 进行恢复
|
||||
5. 下一帧继续正常渲染
|
||||
|
||||
## 关键点说明
|
||||
|
||||
### 为什么需要销毁 Surface？
|
||||
|
||||
虽然 Vulkan 规范中 Surface 不直接依赖于逻辑设备，但在某些平台（特别是 Windows）上：
|
||||
- GPU 驱动重置可能影响 Surface 的底层窗口系统连接
|
||||
- 旧的 Surface 可能与新设备不兼容
|
||||
- 重新创建 Surface 确保与新设备的完全兼容性
|
||||
|
||||
### 为什么不保留 Instance 和 PhysicalDevice？
|
||||
|
||||
- `VkInstance`：Vulkan 加载器级别的对象，不受设备丢失影响，可以保留
|
||||
- `VkPhysicalDevice`：物理设备句柄，表示 GPU 硬件，也不受逻辑设备丢失影响，可以保留
|
||||
- `VkDevice`：逻辑设备，设备丢失后**必须**重新创建
|
||||
- `VkSurface`：虽然理论上可以保留，但为了保证跨平台兼容性，选择重新创建
|
||||
|
||||
### 同步问题
|
||||
|
||||
在清理资源前调用 `vkDeviceWaitIdle()` 确保：
|
||||
- 所有提交的命令都已完成
|
||||
- 没有资源正在被 GPU 使用
|
||||
- 避免在销毁时出现验证层错误
|
||||
|
||||
即使 `vkDeviceWaitIdle()` 因设备丢失而失败，我们仍然继续清理流程，因为：
|
||||
- 设备已丢失，所有命令都已停止
|
||||
- 资源对象仍需要正确释放以避免内存泄漏
|
||||
|
||||
## 测试场景
|
||||
|
||||
1. **正常休眠/唤醒**
|
||||
- 锁定屏幕 → 休眠 → 唤醒 → 解锁
|
||||
- 应该能够正常恢复渲染，无错误
|
||||
|
||||
2. **长时间休眠**
|
||||
- 休眠超过数小时或过夜
|
||||
- GPU 驱动更可能被完全重置
|
||||
- 应该能够检测设备丢失并成功恢复
|
||||
|
||||
3. **多次休眠/唤醒循环**
|
||||
- 连续多次休眠和唤醒
|
||||
- 每次都应该能够正确恢复
|
||||
- 无内存泄漏
|
||||
|
||||
4. **渲染中途设备丢失**
|
||||
- 在活跃渲染期间触发设备丢失
|
||||
- 应该能够捕获错误并恢复
|
||||
|
||||
## 日志输出
|
||||
|
||||
成功恢复的日志示例：
|
||||
|
||||
```
|
||||
📤 系统已从睡眠中唤醒
|
||||
MainWindow: Screen unlocked event received
|
||||
Vulkan rendering ENABLED - Resuming animations
|
||||
Device lost detected on resume, attempting recovery...
|
||||
=== Handling device lost error ===
|
||||
Render timer stopped for device recovery
|
||||
=== Recreating Vulkan device ===
|
||||

|
||||
Sync objects cleaned up
|
||||
Command objects cleaned up
|
||||
Logical device destroyed
|
||||

|
||||

|
||||
Logical device recreated
|
||||

|
||||
Command objects recreated
|
||||

|
||||
VulkanRenderer recreated successfully!
|
||||
=== Device recreation complete ===
|
||||
Device recovery successful!
|
||||
Render timer restarted after recovery
|
||||
```
|
||||
|
||||
## 注意事项
|
||||
|
||||
1. **帧计数器重置**：设备恢复后 `m_currentFrame` 重置为 0，确保同步对象索引正确
|
||||
|
||||
2. **渲染器状态**：VulkanRenderer 会被完全重建，所有内部状态都会重置
|
||||
|
||||
3. **用户体验**：恢复过程通常在 100-500ms 内完成，用户可能会注意到短暂的黑屏或暂停
|
||||
|
||||
4. **错误处理**：如果恢复失败，渲染会被禁用，防止崩溃，用户仍可使用应用的其他功能
|
||||
|
||||
5. **跨平台**：此方案在 Windows、Linux 和 macOS 上都应该工作，但具体行为可能因驱动而异
