当打开wifi或者Ap时，会启动 wifi hal service.
在LINUX/android/frameworks/opt/net/wifi/service/java/com/android/server/wifi/WifiNative.java 中，
在Log.e(TAG, "Failed to start vendor HAL");　中添加FLAG "DTC_WIFI".

private boolean startHal() {
        synchronized (mLock) {
            if (!mIfaceMgr.hasAnyIface()) {
                if (mWifiVendorHal.isVendorHalSupported()) {
                    if (!mWifiVendorHal.startVendorHal()) {
                        Log.e(TAG, "Failed to start vendor HAL");
                        return false;
                    }
                } else {
                    Log.i(TAG, "Vendor Hal not supported, ignoring start.");
                }
            }
            return true;
        }
    }
这个库目前未申请分析，先本地编译验证．

这个是编译的user版本，root后，也不能remount 来制造wifi加载驱动失败。
重新编译userdebug版本来验证。
正式验证时，可以尝试去掉wifi芯片或者断开pcie线来测试。
user-debug版本编译中

软件验证方式：
移除驱动
/vendor/lib/modules/qca_cld3_qca6390.ko

测试条件设置：
1.
adb root
adb remount
adb reboot
2.
adb root
adb remount

adb shell mv /vendor/lib/modules/qca_cld3_qca6390.ko /vendor/lib/modules/qca_cld3_qca6390.ko-bak
adb shell sync
adb reboot

测试结果：WifiNative: DTC_WIFI: Failed to start vendor HAL
添加关键字 DTC_WIFI

hi 王成

没有找到刘强的账号，请帮转一下。
下面是VB的user版本，因不能mount，制造不了软件错误
ftp://cdiot@192.168.87.46/Pre_figure/VerifyBuild/Pre_figure_turbox-c2130c-la1.1-qssi12-dev/20230130/202301302148-2390
如使用user版本测试，请看BSP同事可以帮修改一下板子吗？

谢谢！

Userdebug：
通过上述方法验证通过，制造异常后有以下日志输出：
1001 1684 E WifiNative: DTC_WIFI: Failed to start vendor HAL
恢复正常后，日志消失
报错日志仅打开使用wifi会报出

User由于不能remount，和祥林沟通后，暂时不使用损坏硬件的方式进行测试
