vxWorks下设备驱动模板

.鉴于vxBus的设施驱动模板vxWorks6.x设施驱动采纳了新式的vxBus构架，该构架和本来的设施驱动有很大不一样，初上手会有好多不方便。下边供给的模板有助于迅速形成一个vxBus设施驱动设施驱动在3个地方表现：头文件，代码文件，hwconfig.c,依据下边模板，把全部DEVICE换成自己的设施，并做相应操作即可，免除好多重复代码的烦恼，开发者仅需要关注功能即可。这个模板办理了中止，但没有供给办理基本IO的方法，模板不是用来学习的，如何完好地写一个vxbus的驱动，仍是需要学习的。头文件#ifndefDEVICE_h#defineDEVICE_h#defineDEVICE_CARD_NAME"设施名"#defineDEVICE_CARD_DESC"设施描绘"#defineDEVICE_CARD_VXBNAME"设施vxBus名"#defineDEVICE_CARD_INT_PIN[中止管脚]#defineDEVICE_CARD_INT_CORE_PIN[核中止管脚]#defineDEVICE_CARD_INT_CORE_NUM[中止办理核]Word专业资料.#defineDEVICE_INT_DESC{DEVICE_INT_PIN,DEVICE_CARD_VXBNAME,0,0}#defineDEVICE_XBAR_DESC{DEVICE_INT_PIN,DEVICE_INT_CORE_PIN}#defineDEVICE_ROUTE_DESC{DEVICE_INT_PIN,DEVICE_INT_CORE_NUM}#defineDEVICE_UNIT0_DEVICE_ID0/*若是有多个同型号设施begin*/#defineDEVICE_UNIT1_DEVICE_ID1...../*若是有多个同型号设施end*//*其余设施宏*/#endif/*DEVICE_h*/代码文件#include<vxWorks.h>/*addedforvxBus*/#include<vxBusLib.h>#include<hwif/vxbus/vxBus.h>Word专业资料.#include<hwif/vxbus/vxbPlbLib.h>#include<hwif/vxbus/hwConf.h>#include"DEVICE.h"/*其余必需的INCLUDE*//*设施数据构造*/typedefstruct{VXB_DEVICE_IDpDev;intnVxUnit;/*其余需要的成员变量*/}DEVICE_STRUCT;/*总线加载函数*/LOCALvoidDEVICEInstInit(structvxbDev*pDev);LOCALvoidDEVICEInstInit2(structvxbDev*pDev);LOCALvoidDEVICEInstConnect(structvxbDev*pDev);/*方法函数(若是有的话)*//*探访函数*/LOCALBOOLDEVICEProbe(structvxbDev*pDev);/*中止响应函数*/Word专业资料.LOCALvoidDEVICEInt(DEVICE_STRUCT*pDrvCtrl);/*vxBus注册总线加载函数*/LOCALstructdrvBusFuncsDEVICEFuncs={DEVICEInstInit,/*devInstanceInit*/DEVICEInstInit2,/*devInstanceInit2*/DEVICEInstConnect/*devConnect*/};/*vxBus设施方法函数*/LOCALdevice_method_tDEVICEMethods[]={/*方法函数(若是有的话)*/{0,0}};/*PCI设施需要填写*/LOCALstructvxbPciIDDEVICEDevIDList[]={{DEVICE_DEVID,DEVICE_VENDORID}};/*vxBus设施注册进口*/Word专业资料./*pci设施start*/LOCALstructvxbPciRegisterDEVICERegistration={{NULL,/*pNext*/VXB_DEVID_DEVICE,/*devID*/VXB_BUSID_PCI,/*busID=PCI*/VXBUS_VERSION_4,DEVICE_CARD_VXBNAME,/*设施名称*/&DEVICEFuncs,DEVICEMethods,DEVICEProbe},NELEMENTS(DEVICEDevIDList),DEVICEDevIDList};/*pci设施end*//*plb设施start*/LOCALstructvxbPlbRegisterDEVICERegistration={{Word专业资料.NULL,/*pNext,一般都用NULL*/VXB_DEVID_DEVICE,/*devID,固定,表示这是一个设施*/VXB_BUSID_PLB,/*busID=PLB,表示这个设施挂接在PLB上*/VXBUS_VERSION_4,/*版本号,6.7为版本4*/DEVICE_CARD_VXBNAME,/*设施名称,一定和hwconfig.c中一致*/&DEVICEFuncs,/*pDrvBusFuncs,设施总线函数组在后边定义*/DEVICEMethods,/*pMethods,设施方法组,在后边定义*/DEVICEProbe/*devProbe,设施探测*/}};/*plb设施end*//**************************************总进口***********************************/voidDEVICERegister(void){vxbDevRegister((structvxbDevRegInfo*)&(DEVICERegistration));return;}/*************************************总线接口************************************/LOCALvoidDEVICEInstInit(structvxbDev*pDev){vxbNextUnitGet(pDev);Word专业资料.return;}/*设施初始化*/LOCALvoidDEVICEInstInit2(structvxbDev*pDev){DEVICE_STRUCT*pDrvCtrl;pDrvCtrl=malloc(sizeof(DEVICE_STRUCT));if(pDrvCtrl==NULL)return;bzero((char*)pDrvCtrl,sizeof(DEVICE_STRUCT));pDev->pDrvCtrl=pDrvCtrl;pDrvCtrl->pDev=pDev;/*下边增添硬件要求的代码*/return;}/*设施探访*/LOCALBOOLDEVICEProbe(structvxbDev*pDev){/*PLB标准写法start*/BOOLretVal=TRUE;if(pDev->busID==VXB_BUSID_PLB){Word专业资料.retVal=TRUE;}else{retVal=FALSE;}return(retVal);/*PLB标准写法end*//*PCI写法start*/UINT16venId;UINT16devId;/*子设施ID及硬件版本，若是有的话*//*UINT16subDevId;UINT32hwRev;*/inti;DEVICE_STRUCT*pDrvCtrl;pDrvCtrl=pCev->pDrvCtrl;VXB_PCI_BUS_CFG_READ(pDev,PCI_CFG_VENDOR_ID,2,&venId);VXB_PCI_BUS_CFG_READ(pDev,PCI_CFG_DEVICE_ID,2,&devId);/*查问Bar，并填写到构造里面*/Word专业资料.for(i=0;i<VXB_MAXBARS;i++){/*依据需要填写*/}if(填写过程中有错误)return(FALSE);if((devId!=DEVICE_DEVID)&&(venId!=DEVICE_VENDORID)){printf("cannotfindtheDEVICEdevice\r\n");return(FALSE);}return(TRUE);/*PCI写法end*/}/*挂接中止*/LOCALvoidDEVICEInstConnect(structvxbDev*pDev){/*禁用中止*/DEVICEIntDisable(pDev->pDrvCtrl);/*清中止*/DEVICEIntClear(pDev->pDrvCtrl);Word专业资料./*挂接中止*/if(vxbIntConnect(pDev,0,DEVICEInt,(void*)(pDev->pDrvCtrl))!=OK){printf("DEVICE:vxbIntConnectFail\n");}else{printf("DEVICE:vxbIntConnectOK\n");}if(vxbIntEnable(pDev,0,DEVICEInt,(void*)(pDev->pDrvCtrl))!=OK){printf("DEVICE:vxbIntEnableFail\n");}else{printf("DEVICE:vxbIntEnableOK\n");}/*使能中止*/DEVICEIntEnable(pDev->pDrvCtrl);}Word专业资料./*中止响应函数*/LOCALvoidDEVICEInt(DEVICE_STRUCT*pDrvCtrl){intn;intlockId;n=pDrvCtrl->nVxUnit;lockId=intCpuLock();/*探访本设施中止源*//*办理中止*//*消除本设施中止源*/DEVICEIntClear(pDrvCtrl);intCpuUnlock(lockId);}/*中止控制函数*/LOCALvoidDeviceIntEnableDEVICE_STRUCT*pDrvCtrl){}LOCALvoidDeviceIntDisable(DEVICE_STRUCT*pDrvCtrl){}Word专业资料.LOCALvoidDeviceIntClear(DEVICE_STRUCT*pDrvCtrl){}Hwconfig.c#include"DEVICE.h".....conststructhcfResourceDEVICEResources[]={{"deviceId",HCF_RES_INT,{(void*)(DEVICE_UNIT0_DEVICE_ID)}},/*下边写需要的资源*/};#defineDeviceNumNELEMENTS(DEVICERes
