Review request for Default, Ali Saidi, Gabe Black, Steve Reinhardt, and Nathan
Binkert.
Changes
-------
Thanks. Following your suggestions, I implement a switch in setMiscReg, which
can deal with LLFLAG and LLADDR specially.
Therefore, it doesn't need to change the locked_mem.cc.
Summary
-------
The read/setMiscRegNoEffect are declared in inorder_dyn_inst.hh, but not
defined in inorder_dyn_inst.cc.
I hope the definitions can be added for the future use.
----
The problem is caused by a MIPS linked load instruction. It make the CP0 halt
then restart. After that, the tick becomes a large number and it says 'because
simulate() limit reached'.
Korey Sewell told me:
If you get "simulate() reached", that means your system likely deadlocked
as there are no more events on the main event queue. Run w/the cpu progress
interval on to help determine where the CPUs stops committing instructions.
Also, post the locked_mem.hh patch if you want comments on what you are trying
to do to resolve the problem.
----
I change the locked_mem.hh to an old stable version, to avoid the problem
mentioned above. But I know this is not 'fixing the bug', but 'avoiding the
bug'.
