PCI_VDEVICE 和 PCI_DEVICE 有什么区别？
What is the difference between PCI_VDEVICE and PCI_DEVICE?
PCI_VDEVICE 和 PCI_DEVICE 宏有什么区别？
在内核内部工作时，代码实际上是文档。在这里，你是一个幸运的人，因为这两个宏都有记录（并非总是如此）。看起来它们是等价的，除了 PCI_VDEVICE 不那么冗长。
证明：
/**
* PCI_DEVICE - macro used to describe a specific PCI device
* @vend: the 16 bit PCI Vendor ID
* @dev: the 16 bit PCI Device ID
*
* This macro is used to create a struct pci_device_id that matches a
* specific device. The subvendor and subdevice fields will be set to
* PCI_ANY_ID.
*/
/**
* PCI_VDEVICE - macro used to describe a specific PCI device in short form
* @vend: the vendor name
* @dev: the 16 bit PCI Device ID
*
* This macro is used to create a struct pci_device_id that matches a
* specific PCI device. The subvendor, and subdevice fields will be set
* to PCI_ANY_ID. The macro allows the next field to follow as the device
* private data.
