BLK0: 为一块硬盘；
FS0:HD0b:BLK1: 第一个GPT分区，可识别的文件系统，开始扇区号为0xF000，扇区数为0x200000；
BLK2: 为第二个GPT分区，开始扇区号为0x20F000，扇区数为0x389AB019。dblk 命令通过访问BLK0可以等效访问BLK1或BLK2，只是开始的扇区号相应调整，请看下面例子：
dblk命令是如何读取扇区的？读源代码，再上NDB观察（原过程没有这么顺利，因为发现有代码没有符号，现已经加载上）：
参阅：lm及观察加载的Modules
可以观察到，这里有两块硬盘，访问硬盘时，直接用NvmExpressDxe和MmcDxe驱动，访问分区的扇区，则用PartitionDxe：

美的代码：
UEFI架构设计得真漂亮，NDB断点跟踪执行发现驱动其中有如下调用关系：
Dblk blk4: -> PartitionDxe!PartitionReadBlocks -> DiskIoDxe!DiskIo2ReadWriteDisk -> MmcDxe!MmcReadBlocks
层层翻译得自然而然，下面NDB下断点后得到的调用栈有被简化，有些因为是函数编译时其实用了inline，也有部分可能是NDB对栈解释的问题。
dblk blk0的调用栈：

00000000`3fffed58 00000000`e9cadf74 MmcDxe!MmcIoBlocks

个人感受也是确实如此。
停下来观察用到的断点：

5 e 00000000`e9cada80 e 1 0001 (0001) Shell!ShellCommandRunDblk 从MmcDxe!MmcIoBlocks 再往下深一层，看MmcHost到底是哪个，依然是用NDB下断点：
从list文件搜索到文件偏移位置：
自建Excel查找，从文件偏移算出断点地址：
断点命中，停下来观察：

如果光读源代码，要弄清楚具体此问题，目前已知靠搜索和猜，比较困难。或有高手可告知方法。
