The dataaddress that caused the page fault problem was 0x00 (dar 0000000000000000).
引起页面错误的数据地址为0x00 (dar 0000000000000000)。

The dar (Dataaddress Register) contains the address that the processor tried to access, which then caused a page fault.
dar(数据地址寄存器)包含处理器尝试访问的地址,这一行为将引发页面错误。

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