玩转贝启科技BQ3588C开源鸿蒙系统开发板 —— 语音唤醒失败问题的分析（1）

蓝天居士2024-01-12 11:44

前边经过重重关卡，终于构建好了OpenHarmony系统。而编译好系统只是万里长征走完了第一步，真正的目的是为了实际的项目，以及在完成项目过程中完成具体的任务和实际解决的问题。

这里就开始介绍实际遇到的问题，以及对于它们的分析与解决。

在实际项目中，发现烧录系统后，对于语音唤醒功能进行测试时，并不能正常唤醒，此功能失效。关于语音唤醒这一部分的介绍参见：

鸿蒙（OpenHarmony）系统之智能语音部件（1）

由于笔者也是初次接触OpenHarmony，因此对于此问题采用最直接的方法，从系统日志入手。日志（log）如下（日志文件内容很大，只贴出相关的部分内容）：

虽然只是截取了很少的一部分日志，内容也是比较多的，其中有很多不相关内容需要过滤掉，只关注直接相关的。经过笔者认真观察和手工过滤（搜索"intell_voice"关键字），最为核心的相关内容如下：

bash 复制代码 
01-01 08:00:15.049 617-718/? E C02500/"TriggerManagerImpl": [LoadAdapter][line:109]: get adapter device from hal failed, ret:0

01-01 08:00:15.049 415-1358/? E C02500/intell_voice_trigger_manager_pr: LoadAdapter_ failed, error code is -1
01-01 08:00:15.049 415-1358/? E C02500/TriggerConnector: [TriggerConnector:42]: failed to load adapter, adapterName is primary
01-01 08:00:15.049 415-1358/? W C01510/IPCObjectProxy: 63: handle = 4 destroyed, descriptor: IPCObjectProxy4
01-01 08:00:15.049 1340-1396/? E C01400/OHOS::ROSEN: print log error in vsprintf_s

进而，通过日志可以推出条目前边的号（C02500）是一把"钥匙"，笔者目前理解这个号可能是进程号或者标识一个进程的标志（具体代表什么可以请懂的朋友指出，目前我是这样理解的，意思是这意思）。再以"C02500"关键字作为过滤器，就能够滤除与智能语音（强）相关的日志了。

（1）"get adapter device from hal failed, ret:0"

以"get adapter device from hal failed"为关键字，在OpenHarmony源码根目录下进行搜索，结果如下：

bash 复制代码 
ph@ph-virtual-machine:~/OpenHarmony_Source$ grep -rn "get adapter device from" ./
./drivers/peripheral/intelligent_voice/hdi_service/trigger/intell_voice_trigger_manager_impl.cpp:109:        INTELLIGENT_VOICE_LOGE("get adapter device from hal failed, ret:%{public}d", ret);
./drivers/peripheral/intelligent_voice/hdi_service/engine/intell_voice_engine_manager_impl.cpp:101:        INTELLIGENT_VOICE_LOGE("get adapter device from hal failed");

由于日志中带有"ret:0"，因此是第1个搜素结果。看一下./drivers/peripheral/intelligent_voice/hdi_service/trigger/intell_voice_trigger_manager_impl.cpp文件第109行内容，代码如下：

cpp 复制代码 
int32_t IntellVoiceTriggerManagerImpl::LoadAdapter(const IntellVoiceTriggerAdapterDsecriptor &descriptor,
    sptr<IIntellVoiceTriggerAdapter> &adapter)
{
    std::lock_guard<std::mutex> lock(mutex_);

    if (inst_ == nullptr) {
        INTELLIGENT_VOICE_LOGE("inst is nullptr");
        return HDF_FAILURE;
    }

    auto it = halAdapters_.find(descriptor.adapterName);
    if (it != halAdapters_.end()) {
        INTELLIGENT_VOICE_LOGW("adapter %{public}s already exist", descriptor.adapterName.c_str());
        inst_->UnloadAdapter(descriptor);
        it->second = nullptr;
        halAdapters_.erase(it);
    }

    std::unique_ptr<ITrigger> triggerAdapterDevice = nullptr;
    int32_t ret = inst_->LoadAdapter(descriptor, triggerAdapterDevice);
    if (triggerAdapterDevice == nullptr) {
        INTELLIGENT_VOICE_LOGE("get adapter device from hal failed, ret:%{public}d", ret);
        return HDF_FAILURE;
    }

    adapter = sptr<IIntellVoiceTriggerAdapter>(new (std::nothrow) IntellVoiceTriggerAdapterImpl(
        std::move(triggerAdapterDevice)));
    if (adapter == nullptr) {
        INTELLIGENT_VOICE_LOGE("new adapter failed");
        return HDF_ERR_MALLOC_FAIL;
    }

    halAdapters_[descriptor.adapterName] = adapter;
    return HDF_SUCCESS;
}

IntellVoiceTriggerManagerImpl::LoadAdapter()中的以下一行打印出了日志信息：

cpp 复制代码 
INTELLIGENT_VOICE_LOGE("get adapter device from hal failed, ret:%{public}d", ret);

相关上下文如下：

cpp 复制代码 
    std::unique_ptr<ITrigger> triggerAdapterDevice = nullptr;
    int32_t ret = inst_->LoadAdapter(descriptor, triggerAdapterDevice);
    if (triggerAdapterDevice == nullptr) {
        INTELLIGENT_VOICE_LOGE("get adapter device from hal failed, ret:%{public}d", ret);
        return HDF_FAILURE;
    }

由代码可见，之所以会打印出此信息，是由于调用"inst_->LoadAdapter(descriptor, triggerAdapterDevice);"之后，triggerAdapterDevice仍然是nullptr。

（2）"intell_voice_trigger_manager_st: IntellVoiceTriggerManagerStubLoadAdapter_ failed, error code is -1"

这次不直接搜索，而是直接找到Open Harmony源码根目录/out/rk3588/gen/drivers/interface/intelligent_voice/trigger/v1_0/intell_voice_trigger_manager_stub.cpp文件 。并在其中以"failed, error code is"为关键字进行搜索，可知其在以下函数中：

cpp 复制代码 
int32_t OHOS::HDI::IntelligentVoice::Trigger::V1_0::IntellVoiceTriggerManagerStub::IntellVoiceTriggerManagerStubLoadAdapter_(MessageParcel& intellVoiceTriggerManagerData, MessageParcel& intellVoiceTriggerManagerReply, MessageOption& intellVoiceTriggerManagerOption, sptr<OHOS::HDI::IntelligentVoice::Trigger::V1_0::IIntellVoiceTriggerManager> impl)
{
    if (intellVoiceTriggerManagerData.ReadInterfaceToken() != OHOS::HDI::IntelligentVoice::Trigger::V1_0::IIntellVoiceTriggerManager::GetDescriptor()) {
        HDF_LOGE("%{public}s: interface token check failed!", __func__);
        return HDF_ERR_INVALID_PARAM;
    }

    IntellVoiceTriggerAdapterDsecriptor descriptor;
    if (!IntellVoiceTriggerAdapterDsecriptorBlockUnmarshalling(intellVoiceTriggerManagerData, descriptor)) {
        HDF_LOGE("%{public}s: read descriptor failed!", __func__);
        return HDF_ERR_INVALID_PARAM;
    }

    sptr<OHOS::HDI::IntelligentVoice::Trigger::V1_0::IIntellVoiceTriggerAdapter> adapter;

    if (impl == nullptr) {
        HDF_LOGE("%{public}s: impl is nullptr!", __func__);
        return HDF_ERR_INVALID_PARAM;
    }

    int32_t intellVoiceTriggerManagerRet = impl->LoadAdapter(descriptor, adapter);
    if (intellVoiceTriggerManagerRet != HDF_SUCCESS) {
        HDF_LOGE("%{public}s failed, error code is %{public}d", __func__, intellVoiceTriggerManagerRet);
        return intellVoiceTriggerManagerRet;
    }

    if (adapter == nullptr) {
        HDF_LOGE("%{public}s: parameter adapter is nullptr!", __func__);
        return HDF_ERR_INVALID_PARAM;
    }

    if (!intellVoiceTriggerManagerReply.WriteRemoteObject(OHOS::HDI::ObjectCollector::GetInstance().GetOrNewObject(adapter, OHOS::HDI::IntelligentVoice::Trigger::V1_0::IIntellVoiceTriggerAdapter::GetDescriptor()))) {
        HDF_LOGE("%{public}s: write adapter failed!", __func__);
        return HDF_ERR_INVALID_PARAM;
    }

    return intellVoiceTriggerManagerRet;
}

相关代码片段如下：

cpp 复制代码 
    int32_t intellVoiceTriggerManagerRet = impl->LoadAdapter(descriptor, adapter);
    if (intellVoiceTriggerManagerRet != HDF_SUCCESS) {
        HDF_LOGE("%{public}s failed, error code is %{public}d", __func__, intellVoiceTriggerManagerRet);
        return intellVoiceTriggerManagerRet;
    }

（3）"intell_voice_trigger_manager_pr: LoadAdapter_ failed, error code is -1"

以"intell_voice_trigger_manager_pr"为关键字，在OpenHarmony源码根目录下进行搜索，在众多结果中定位到：

bash 复制代码 
./out/rk3588/gen/drivers/interface/intelligent_voice/trigger/v1_0/intell_voice_trigger_manager_proxy.cpp:16:#include "v1_0/intell_voice_trigger_manager_proxy.h"
./out/rk3588/gen/drivers/interface/intelligent_voice/trigger/v1_0/intell_voice_trigger_manager_proxy.cpp:26:#define HDF_LOG_TAG    intell_voice_trigger_manager_proxy

打开

./out/rk3588/gen/drivers/interface/intelligent_voice/trigger/v1_0/intell_voice_trigger_manager_proxy.cpp文件 ，并在其中以"failed, error code is"为关键字进行搜索，可知其在以下函数中：

cpp 复制代码 
int32_t OHOS::HDI::IntelligentVoice::Trigger::V1_0::IntellVoiceTriggerManagerProxy::LoadAdapter_(const IntellVoiceTriggerAdapterDsecriptor& descriptor, sptr<OHOS::HDI::IntelligentVoice::Trigger::V1_0::IIntellVoiceTriggerAdapter>& adapter, const sptr<IRemoteObject> remote)
{
    MessageParcel intellVoiceTriggerManagerData;
    MessageParcel intellVoiceTriggerManagerReply;
    MessageOption intellVoiceTriggerManagerOption(MessageOption::TF_SYNC);

    if (!intellVoiceTriggerManagerData.WriteInterfaceToken(OHOS::HDI::IntelligentVoice::Trigger::V1_0::IIntellVoiceTriggerManager::GetDescriptor())) {
        HDF_LOGE("%{public}s: failed to write interface descriptor!", __func__);
        return HDF_ERR_INVALID_PARAM;
    }

    if (!IntellVoiceTriggerAdapterDsecriptorBlockMarshalling(intellVoiceTriggerManagerData, descriptor)) {
        HDF_LOGE("%{public}s: write descriptor failed!", __func__);
        return HDF_ERR_INVALID_PARAM;
    }

    int32_t intellVoiceTriggerManagerRet = remote->SendRequest(CMD_INTELL_VOICE_TRIGGER_MANAGER_LOAD_ADAPTER, intellVoiceTriggerManagerData, intellVoiceTriggerManagerReply, intellVoiceTriggerManagerOption);
    if (intellVoiceTriggerManagerRet != HDF_SUCCESS) {
        HDF_LOGE("%{public}s failed, error code is %{public}d", __func__, intellVoiceTriggerManagerRet);
        return intellVoiceTriggerManagerRet;
    }

    if (!ReadInterface<OHOS::HDI::IntelligentVoice::Trigger::V1_0::IIntellVoiceTriggerAdapter>(intellVoiceTriggerManagerReply, adapter)) {
        HDF_LOGE("%{public}s: failed to read interface object", __func__);
        return HDF_ERR_INVALID_PARAM;
    }

    return intellVoiceTriggerManagerRet;
}

相关代码片段如下：

cpp 复制代码 
    int32_t intellVoiceTriggerManagerRet = remote->SendRequest(CMD_INTELL_VOICE_TRIGGER_MANAGER_LOAD_ADAPTER, intellVoiceTriggerManagerData, intellVoiceTriggerManagerReply, intellVoiceTriggerManagerOption);
    if (intellVoiceTriggerManagerRet != HDF_SUCCESS) {
        HDF_LOGE("%{public}s failed, error code is %{public}d", __func__, intellVoiceTriggerManagerRet);
        return intellVoiceTriggerManagerRet;
    }

（4）"TriggerConnector: [TriggerConnector:42]: failed to load adapter, adapterName is primary"

以"failed to load adapter, adapterName"为关键字，在OpenHarmony源码根目录下进行搜索，在众多结果中定位到：

bash 复制代码 
./foundation/ai/intelligent_voice_framework/services/intell_voice_trigger/server/connector_mgr/trigger_connector.cpp:42:            INTELL_VOICE_LOG_ERROR("failed to load adapter, adapterName is %{public}s", desc_.adapterName.c_str());
./foundation/ai/intelligent_voice_framework/services/intell_voice_trigger/server/connector_mgr/trigger_connector.cpp:108:            INTELL_VOICE_LOG_ERROR("failed to load adapter, adapterName is %{public}s", desc_.adapterName.c_str());

打开

./foundation/ai/intelligent_voice_framework/services/intell_voice_trigger/server/connector_mgr/trigger_connector.cpp文件 。根据上边的信息，该文件中共有两处可以产生此日志。到底是哪一处？笔者更倾向于第一处，即构造函数中。代码如下：

cpp 复制代码 
TriggerConnector::TriggerConnector(const IntellVoiceTriggerAdapterDsecriptor &desc)
{
    desc_.adapterName = desc.adapterName;
    auto mgr = IIntellVoiceTriggerManager::Get();
    if (mgr != nullptr) {
        mgr->LoadAdapter(desc_, adapter_);
        if (adapter_ == nullptr) {
            INTELL_VOICE_LOG_ERROR("failed to load adapter, adapterName is %{public}s", desc_.adapterName.c_str());
        }
    } else {
        INTELL_VOICE_LOG_INFO("can not get intell voice trigger manager");
    }
}

至此，与语音唤醒即intelligent voice相关的日志及其出处（出自于哪个文件中的哪个函数）就弄清楚了。下一回开始对于函数的调用流程进行分析。
