通过IRP_MN_START_DEVICE读取PCI物理地址是0xf7bff000，同时长度为0，而通过RW-Read write软件查看PCI卡的物理地址是0xF7bef000，代码是按《windows驱动开发技术指南》中读取PCI设备驱动test来读取的。我通过WDF编写一个测试程序读取PCI物理内存也是0xf7bff000，求教，我读取PCI卡内存物理地址错误问题出在那，谢谢

你好，我按PCI设备的WDM驱动程序设计-9052中IRP_MN_START_DEVICE改写我的代码，打印的值还是0xf7ff000,而不是0xf7ef000.据图打印如下
Port RegsPhybase = 0XF7BFF000 and Hight = 0x0 and Low = 0x0 and uHight = 0xf7bff000 and uLow = 0x0
KdPrint(("Port RegsPhybase = 0X%08X and Hight = 0x%x and Low = 0x%x and uHight = 0x%x and uLow = 0x%x\n",pdx->RegsTempPhybase ,\
pdx->RegsTempPhybase.HighPart,pdx->RegsTempPhybase.LowPart,pdx->RegsTempPhybase.u.HighPart,pdx->RegsTempPhybase.u.LowPart ));
