实施例四：
本实施提供一种基于PCIe的多通道数据处理方法，应用于Linux系统中，先在该Linux系统中添加基于PCIe的驱动模块，然后通过该基于PCIe的多通道数据处理方法，实现系统中PCIe主机和PCIe设备间的多通道数据处理。请参见图6，系统中的设备通过该基于PCIe的多通道数据处理方法，实现与PCIe主机的多通道数据处理，包括：
步骤S601，判断PCIe设备是否支持多通道特性，若不支持，则跳转到步骤S602；若支持，跳转到步骤S603。
PCIe设备上电后，根据该PCIe设备需要支持的功能个数情况判断是否需要支持多通道传输特性，若该PCIe设备是单功能设备，只支持一个功能，则说明其不支持该多通道传输特性，此时不需要生成包含多通道标识信息的Capability结构，该PCIe设备与对应PCIe主机间进行常见的单通道数据传输处理即可。若该PCIe设备支持两个或两个以上功能，即该PCIe设备是多功能设备，此时该PCIe设备需要与对应的PCIe主机间进行多通道数据传输，则根据该PCIe设备支持的功能个数和类型生成对应的多通道传输特性Capability结构，并上报给PCIe主机。
步骤S602，与PCIe主机间进行传统单通道数据传输。
步骤S603，生成包含多通道标识信息的Capability结构。
生成包含多通道标识信息的Capability结构的过程包括:当PCIe设备支持多个功能时，先定义用于传输该功能对应数据的虚拟通道，每个虚拟通道即为一个Chanel，每个PCIe设备可以支持多个Chanel，不同的Chanel用来独立传输不同类型的数据；其次定义Chanel ID概念，每个Chanel有其唯一的通道标识，Chanel ID为该通道标识中的一种，则该Chanel ID与PCIe设备实际支持的功能一一对应。即不同类型的数据对于的数据包拥有不同的Chanel ID，占用不同的Chanel，实现不同的功能。PCIe总线规范要求PCIe设备必须支持Capabilities结构，即在PCIe总线的基本配置空间中，可以包含一个Capabilities Pointer寄存器，该寄存器存放Capabilities结构链表的头指针。在一个PCIe设备中，可能含有多个Capability结构，这些寄存器组成一个链表。其中每一个Capability结构都有唯一的ID号，每一个Capability寄存器都有一个指针，这个指针指向下一个Capability结构，从而组成一个单向链表结构，这个链表的最后一个Capability结构的指针为0。通常PCIe设备与PCIe主机间通过该Capabilities结构进行部分信息的传输，所以本实施中，可以定义一个用来上报多通道标识信息的Capability结构，该多通道标识信息可以是多通道Chanel信息，该Capability结构至少包括配置的PCIe设备Chanel ID组信息，该Capability结构中也可以包含该PCIe设备的Chanel的总个数。
本实施例中，该PCIe设备可以是支持DIAG(diagnostics，诊断信息)端口，AT(Attention，通讯指令)端口，MODEM(调制解调器)端口和NDIS(Network Driver Interface Specification，网络驱动接口规范)端口共4个功能端口的设备；其中，DIAG端口用于设备诊断信息传输，AT端口用于AT命令交互，MODEM端口用于AT以及PPP(point to point protocol，点对点协议)协议报号联网，NDIS端口用于实现虚拟网卡联网。即本实施例中的PCIe设备支持4个通道，每个通道的Chanel ID分别是0x01，0x02，0x03和0x04，其中Chanel Number是0x04，每个Chanel ID对应的功能依次为diag，AT，MODEM和NDIS。针对该四个端口设置Chanel ID可以如下表所示：
Chanel ID 功能 功能描述
0x01 diag 设备诊断信息传输端口
0x02 AT AT命令交互端口
0x03 MODEM AT及PPP协议报号联网端口
0x04 NDIS 虚拟网卡端口
针对该四个端口功能，设置好Chanel ID后，根据该Chanel ID生成对应的Capabilities结构，其可如下表所示：
Figure PCTCN2017085178-appb-000001
本实施例中，在设置好各功能对应的Chanel ID后，或者在生成上述Capabilities结构后，PCIe设备根据该Chanel ID信息完成本地多通道数据处理配置，在后续与PCIe主机间进行数据处理时，根据该Chanel ID进行数据处理，即使得进行传输的数据能携带正确的Chanel ID，将接收到的数据根据Chanel ID发送到对应的数据处理功能单元。
步骤S604，将Capabilities结构上报给PCIe主机。
为实现PCIe设备与PCIe主机间的数据处理，需要PCIe主机根据PCIe设备生成的多通道标识信息完成多通道数据处理配置，则该PCIe设备需要将包含多通道标识信息的Capabilities结构上报给PCIe主机。
步骤S605，PCIe主机解析PCIe设备生成的Capabilities结构，判断该PCIe设备是否支持多通道传输特性；若不支持，则跳转到步骤S606；若支持，则跳转到步骤S607。
在PCIe设备和PCIe主机都上电的情况下，PCIe主机读取该PCIe设备上报的Capabilities结构，并对该Capabilities结构进行解析，判断该PCIe设备是否支持多通道传输特性，通过判断该Capabilities结构中是否包含对应的Chanel ID，或Chanel ID和Chanel ID个数信息，若存在，则说明该PCIe设备支持多通道传输特性；若不存在，则说明该PCIe设备不支持多通道传输特性。
步骤S606，与PCIe设备进行传统单通道数据传输。
步骤S607，根据该Capabilities结构中的多通道标识信息进行多通道数据处理配置。
PCIe主机解析出Capabilities结构中的Chanel ID，或Chanel ID和Chanel ID个数信息，然后在系统中注册对应数量的功能设备，实现软件层面的初始配置，即注册对应数量的用于处理该Chanel ID对应的数据的数据处理功能单元，该数据处理功能单元可以是指对应于该Chanel ID的功能协议栈。后续在数据处理时，根据该Chanel ID进行数据处理，即使得进行传输的数据能携带正确的Chanel ID，将接收到的数据根据Chanel ID发送到对应的数据处理功能单元。
步骤S608，进行数据处理。
在PCIe主机完成多通道配置处理后，该PCIe主机可以与PCIe设备之间进行多通道数据传输，并且PCIe主机和PCIe设备也可以对接收到的多通道传输数据进行相应处理。PCIe设备向PCIe主机发送数据时，根据该数据的数据类型，查找对应的Chanel ID，然后将该Chanel ID添加到该数据对应的数据包中，将该数据包发送给PCIe主机。PCIe主机接收到PCIe设备发送来的数据包时，先从该数据包中解析出Chanel ID，然后根据该Chanel ID判断该数据对应的数据处理功能单元，将该数据或数据包传输到对应的数据处理功能单元进行相应处理。PCIe主机向PCIe设备发送数据时，根据该数据的数据类型，查找对应的 Chanel ID，然后将该Chanel ID添加到该数据对应的数据包中，将该数据包发送给PCIe设备。PCIe设备接收到PCIe主机发送来的数据包时，先从该数据包中解析出Chanel ID，然后根据该Chanel ID判断该数据对应的数据处理功能单元，将该数据或数据包传输到对应的数据处理功能单元进行相应处理。本实施例中的数据处理功能单元可以是指在PCIe设备和PCIe主机与该数据类型对应的协议栈。另外，PCIe主机发送到PCIe设备的数据包，是根据数据包对应的数据类型，添加对应的Chanel ID，并调用注册的PCIe接口write函数，传送到对应的PCIe设备；PCIe主机接收到PCIe设备发送的数据时，通过调用其根据Chanel ID注册的对应设备驱动的read函数，进行数据包解析处理。
本实施例中，PCIe主机与PCIe设备间传输的数据包的格式可如下表所示：其中Date header是数据包的包头，用于存放该数据对应的Chanel ID信息，Date字段用于存放数据信息。DIAG数据包的data header中包含0x01的Chanel ID，AT数据包的data header中包含0x02的Chanel ID，MODEM数据包的data header中包含0x03的Chanel ID，NDIS数据包的data header中包含0x04的Chanel ID。
