WebVTT中的文本轨道（Text Tracks，TT）到底是什么鬼？ WebVTT，全称是The Web Video Text Tracks Format，意思是网络视频文本轨道格式。那么到底什么是文本轨道（Text Tracks）呢？这篇文章希望一探究竟。阅读详情

使用AMD的最新X86 APU做驱动开发:使用DDK函数读写主板芯片组寄存器出错，请教

安装了XP＋SP3，使用200的DDK进行驱动开发，
对于读写I/O映射空间的以下函数
8位输入:UCHAR READ_PORT_UCHAR((PUCHAR)port)
16位输入:USHORT READ_PORT_USHORT((PUSHORT)port)
32位输入:ULONG READ_PORT_ULONG((PULONG)port)

8位输出:WRITE_PORT_UCHAR((PUCHAR)port,(UCHAR)value)
16位输出:WRITE_PORT_USHORT((PUSHORT)port,(USHORT)value)
32位输出:WRITE_PORT_ULONG((PULONG)port,(ULONG)value)
可以正常使用；

对于蜂鸣器可以操作(操作端口0x40h-0x43h和ox61h)，可以通过oxCF8h和0xCFC端口读出挂载在内部PCI线上的Configuration Register区域数据。

但是如果我要读写芯片组上的寄存器{对与内存映射的空间的读写}，在自己编写的驱动程序中使用READ_REGISTER_ULONG函数，在应用程序上使用DeviceIoControl调用驱动程序的READ_REGISTER_ULONG函数，在DriverMonitor软件中提示:
1853.922 Win32 RTL: RtlNtStatusToDosError(0xc0000232): No Valid Win32 Error Mapping
1853.922 Default Enter HelloDDKDispatchRoutin

1853.922 Default Leave HelloDDKDeviceIOControl
1853.938 Win32 RTL: RtlNtStatusToDosError(0xc0000232): No Valid Win32 Error Mapping

这样的信息，

请教这些对于内存映射的空间的读写的DDK函数，关于函数的参数问题，使用上要注意啥？
最好给出个实际例子

问题找到了，是地址映射出了问题。
可以加我QQ

直接读写IO的方法来获取PCI Config的方法，在XP以上是不被推荐的，主要是在多核cpu上有同步问题，但是一般也不会有什么问题。
如果你只想做IO操作，那么用Winio这个驱动好了，没必要自己写。具体你可以搜索一下winio

贴上Driver.cpp的HelloDDKDeviceIOControl函数,在对内存映射范围的寄存器读写使用了READ_REGISTER_ULONG和WRITE_REGISTER_ULONG函数:
