platform_driver_register中添加device到内核最终还是调用的device_add函数。 Platform_device_add和device_add最主要的区别是多了一步insert_resource(p, r),即将platform资源(resource)添加进内核,由内核统一管理。 驱动 驱动注册中,需要实现的结构体是:platform_driver 。 在驱动程序的初始化函数中,调用了platform_dri...

It seems there is some confusion about structib_device_attr.vendor_id:mthca and mlx4 are using an OUI for vendor_id, while ipath and cxgb3use the PCI vendor ID (and I don't know what ehca does). Since these namespaces are not coordinated, there is the (remote) chance of a ...
