here, i have other questions about these information.
what dose mean by "NIP : C01A2108" ? i supposed "C01A2108" may be a address
of user space,
what about NIP ?
and what the expression "DAR, DSISR, TASK, and GPR00-24" represent.
i hope some will let me know those or recommand some book for me. thanks
