高通平台--camera驱动代码结构

1、camx/src/core

sensor、manager、pipeline等结构的实现

camxpipeline.h

/// @brief Pipeline create input data
struct PipelineCreateInputData
{
ChiContext* pChiContext; ///< ChiContext pointer
const PipelineDescriptor* pPipelineDescriptor; ///< Pipeline descriptor
UINT pipelineIndex; ///< Pipeline Index from the Session
BOOL isRealTime; ///< Is it a real time pipeline

BOOL isSecureMode; ///< Mode of pipeline Secure/Non-secure
};

/// @brief Pipeline create output data
struct PipelineCreateOutputData
{
Pipeline* pPipeline; ///< Created pipeline
UINT32 numInputs; ///< Number of inputs
/// @todo (CAMX-1512) Instead of Chi structures use wrappers
ChiPipelineInputOptions* pPipelineInputOptions; ///< Input buffer requirements for the create pipeline
};

camxnode.h

/// @brief Node create input data
struct NodeCreateInputData
{
const PerNodeInfo* pNodeInfo; ///< Node info
Camera3Stream** ppCamera3Streams; ///< Camera3 streams
Pipeline* pPipeline; ///< Pipeline pointer
UINT pipelineNodeIndex; ///< This node instance's index in the pipeline nodes
const HwFactory* pFactory; ///< HwFactory pointer
ChiContext* pChiContext; ///< Chi Context
ChiNodeCallbacks* pChiNodeCallbacks; ///< CHINode callbacks pointer
CHIAFALGORITHMCALLBACKS* pAFAlgoCallbacks; ///< Algo Calllback Interface for Chi
CHIAECALGORITHMCALLBACKS* pAECAlgoCallbacks; ///< Algo Calllback Interface for Chi
CHIAWBALGORITHMCALLBACKS* pAWBAlgoCallbacks; ///< Algo Calllback Interface for Chi
CHIAFDALGORITHMCALLBACKS* pAFDAlgoCallbacks; ///< Algo Calllback Interface for Chi
CHIASDALGORITHMCALLBACKS* pASDAlgoCallbacks; ///< Algo Calllback Interface for Chi
CHIPDLIBRARYCALLBACKS* pPDLibCallbacks; ///< Algo Calllback Interface for Chi
CHIISPHVXALGORITHMCALLBACKS* pHVXAlgoCallbacks; ///< HVX Algo Callback Interface for Chi
};
/// @brief Node create output data
struct NodeCreateOutputData
{
Node* pNode; ///< Created node object pointer
const CHAR* pNodeName; ///< Name of the node (filled in the by the derived node)
NodeCreateFlags createFlags; ///< Create flags
UINT maxNumCmdBufferManagers; ///< Max require number of command buffer managers
UINT maxOutputPorts; ///< Max number of output ports supported
UINT maxInputPorts; ///< Max number of input ports supported
BufferGroup bufferComposite; ///< Buffer composite info
};

/// @brief Node capture request data.
struct NodeProcessRequestData
{
CaptureRequest* pCaptureRequest; ///< Stream configuration pointer
DependencyUnit dependencyInfo[MaxDependencies]; ///< List of Dependency info that will be reported back
/// to topology. Each element in the list is a set of
/// property and buffer dependencies
UINT numDependencyLists; /// Number of entries in the Dependency List
PerBatchedFrameInfo* pPerBatchedFrameInfo; ///< Per batched frame info
INT32 processSequenceId; ///< Identifier for the node to track its processing order
BOOL bindIOBuffers; ///< Flag indicating whether node requested input, output buffers
/// to be available on this sequenceId
BOOL isSequenceIdInternal; ///< True if processSequenceId belongs to base node
};

camxsession.h

/// @brief Pipeline descriptor handle used to describe a pipeline
struct PipelineDescriptor
{
PerPipelineInfo pipelineInfo; ///< Pipeline info that will be used to create the
/// actual pipeline object
UINT numOutputs; ///< Number of outputs (<= MaxPipelineOutputs)
PipelineOutputData outputData[MaxPipelineOutputs]; ///< Output data
UINT numInputs; ///< Number of inputs (<= MaxPipelineInputs)
PipelineInputData inputData[MaxPipelineInputs]; ///< Input data for this pipeline
PipelineDescriptorFlags flags; ///< Flags
UINT numBatchedFrames; ///< Number of framework frames batched
UINT maxFPSValue; ///< maxFPSValue info of batched frames
UINT32 cameraId; ///< Camera Id of pipeline
CHAR pipelineName[MaxStringLength256]; ///< Name of this pipeline
VOID* pPrivData; ///< Camx private data, carrying pipeline obj ptr.
MetaBuffer* pSessionMetadata; ///< Metadata buffer published by the Chi Usecase
};

2、camx/src/core/hal

camera provider 在hal的接口实现

3、camx/src/core/chi

主要是于chi api的函数映射相关文件

4、camx/src/swl

软件流程和node实现，包括stats、jpeg、sensor等

5、camx/src/hwl

硬件相关流程与node的实现，平台支持。包括ife，bps，ipe等

6、vendor/qcom/proprietary/chi-cdk/vendor

chi api ，即hal3的拓展部分

actuator ：VCM驱动配置

sensor：sensor驱动配置

eeprom：eeprom驱动配置

module：模组驱动配置

flash：闪光灯驱动配置

fd：人脸参数配置

tuning：效果调试参数

ois：ois驱动配置

node：各个node的实现

topology：拓扑图xml
