机器状态寄存器(Machine State Register,MSR)是64位寄存器。

The Machine State register (MSR) is a 64-bit register.

在调试信号时，需要查看的一些重要寄存器包括GPR、指令指针(NIP)、机器状态寄存器(MSR)、Trap、数据地址寄存器(DAR)等等。

Important registers to look for when debugging through signals are the GPRs, instruction pointer (NIP), machine state register (MSR), trap, data address register (DAR), and so on.
