PCIe 之TW68XX驱动

PCIe驱动：TW68XX驱动
主要数据结构、函数记录如下：
1、struct pci_driver：
程序中调用 pci_register_driver(&TW68_pci_driver); 实现注册。

TW68_pci_driver 定义：

static struct pci_driver TW68_pci_driver = {    .name     = "TW6868",    .id_table = TW68_pci_tbl,    .probe    = TW68_initdev,    .remove   = __devexit_p(TW68_finidev),//#ifdef CONFIG_PM//  .suspend  = TW6868_suspend,//  .resume   = TW6868_resume//#endif};

pci_driver原型：

 struct pci_driver {    struct list_head node;    const char *name;    const struct pci_device_id *id_table;   /* must be non-NULL for probe to be called */    int  (*probe)  (struct pci_dev *dev, const struct pci_device_id *id);   /* New device inserted */    void (*remove) (struct pci_dev *dev);   /* Device removed (NULL if not a hot-plug capable driver) */    int  (*suspend) (struct pci_dev *dev, pm_message_t state);  /* Device suspended */    int  (*suspend_late) (struct pci_dev *dev, pm_message_t state);    int  (*resume_early) (struct pci_dev *dev);    int  (*resume) (struct pci_dev *dev);                   /* Device woken up */    void (*shutdown) (struct pci_dev *dev);    struct pci_error_handlers *err_handler;    struct device_driver    driver;    struct pci_dynids dynids;};

pci_device_id 原型：

struct pci_device_id {    __u32 vendor, device;       /* Vendor and device ID or PCI_ANY_ID*/    __u32 subvendor, subdevice; /* Subsystem ID's or PCI_ANY_ID */    __u32 class, class_mask;    /* (class,subclass,prog-if) triplet */    kernel_ulong_t driver_data; /* Data private to the driver */}; 

实例：

程序中已经实现了pci_device_id、probe以及remove成员。
