# RAIDGuard X Mock Driver (C)
Mock driver for RAIDGuard X GUI Server - provides simulated RAID controller for testing without hardware.
## 目錄結構

├── mock_driver.h # Header file
├── mock_driver.c # Implementation
├── test_mock_driver.c # Test program
├── Makefile # Build file
└── README.md # This file
```
## 建構
```bash
make
```
## 執行測試
```bash
./test_mock_driver
```
## 使用方式
### 1. 初始化
```c
#include "mock_driver.h"
// 初始化 Mock Driver
mock_init();
// 啟用詳細輸出
mock_set_verbose(true);
```
### 2. 設定控制器
```c
// 設定控制器數量 (預設 1)
mock_set_controller_count(2);
// 設定控制器序號
mock_set_controller_serial(0, "MOCK00000001");
mock_set_controller_serial(1, "MOCK00000002");
// 設定控制器型號
mock_set_controller_model(0, "Accusys GEN2");
```
### 3. 查詢控制器資訊
```c
UCHAR pageBuf[1024];
UCHAR heatsink;
// 查詢控制器資訊
CHAR result = mock_QuaryDTR(0, pageBuf, &heatsink);
if (result == 1) {
// 取得序號
printf("SN: %.16s\n", pageBuf);
// 取得型號
printf("Model: %.20s\n", pageBuf + 16);
// 取得韌體版本
printf("FW: %.8s\n", pageBuf + 64);
}
```
### 4. 取得事件
```c
EVENT_INFO evt;
UCHAR result = mock_GetCtlrEvent(0, &evt);
if (result == SYSOK && evt.bStatus) {
// 處理事件
printf("Event Type: %d\n", evt.bEventBuf[0]);
}
```
### 5. 模擬事件
```c
// 模擬磁碟上線事件
mock_generate_disk_event(5, 0x01);
// 模擬 RAID 重建事件
mock_generate_raid_event(0, 0x02);
// 自訂事件
UCHAR customEvent[] = {
0x03, 0x00, 0x00, 0x00, // Event Type
0x00, 0x00, 0x00, 0x00, // Timestamp
0x00, 0x00, 0x00, 0x00, // Data
0x00, 0x00, 0x00, 0x00
};
mock_push_event(customEvent, 16);
```
### 6. 清理
```c
mock_cleanup();
```
## API 參考
### 初始化與清理
| 函數 | 說明 |
|------|------|
| `mock_init()` | 初始化 Mock Driver |
| `mock_cleanup()` | 清理資源 |
| `mock_set_verbose(bool)` | 設定詳細輸出 |
### 控制器設定
| 函數 | 說明 |
|------|------|
| `mock_set_controller_count(int)` | 設定控制器數量 |
| `mock_set_controller_serial(int, const char*)` | 設定控制器序號 |
| `mock_set_controller_model(int, const char*)` | 設定控制器型號 |
| `mock_set_controller_status(int, UCHAR)` | 設定控制器狀態 |
### Driver 函數
| 函數 | 說明 |
|------|------|
| `mock_QuaryDTR(UCHAR, UCHAR*, UCHAR*)` | 查詢控制器資訊 |
| `mock_DevIoControl(...)` | I/O Control (模擬) |
| `mock_GetCtlrEvent(UCHAR, EVENT_INFO*)` | 取得事件 |
### 事件模擬
| 函數 | 說明 |
|------|------|
| `mock_push_event(UCHAR*, int)` | 推入自訂事件 |
| `mock_clear_events()` | 清除所有事件 |
| `mock_generate_disk_event(int, int)` | 產生磁碟事件 |
| `mock_generate_raid_event(int, int)` | 產生 RAID 事件 |
## 模擬的 Page 資料
| Page | 大小 | 內容 |
|------|------|------|
| 0x00 | 1024 | Controller Info |
| 0x01 | 1024 | RAID Snapshot |
| 0x07 | 512 | LUN Map Table |
| 0x0A | 1024 | RAID Info |
| 0x0B | 1024 | RAID Info |
| 0x0E | 1024 | RAID Info |
| 0x1B | 512 | Disk List |
## 整合到 GS
要將 Mock Driver 整合到 GS (DtrGuiSrv),請在編譯時使用 `-DENABLE_MOCK_MODE`
```makefile
ifdef ENABLE_MOCK_MODE
CFLAGS += -DENABLE_MOCK_MODE
SRCS += mock_driver.c
# 置換函數
CFLAGS += -DQuaryDTR=mock_QuaryDTR
CFLAGS += -DDevIoControl=mock_DevIoControl
CFLAGS += -DGetCtlrEvent=mock_GetCtlrEvent
endif
```
或使用 FFI
```c
#ifdef ENABLE_MOCK_MODE
#include "mock_driver.h"
#define DevIoControl mock_DevIoControl
#define QuaryDTR mock_QuaryDTR
#define GetCtlrEvent mock_GetCtlrEvent
#endif
```
## 開發日誌
- 2024-03-29: 初始版本
- 基本控制器模擬
- 事件佇列
- Page 0-1, 7, 10, 27 資料
