Re: [Gems-users] Read and write misses

[Mike Marty <mikem@xxxxxxxxxxx>]

You will need to add some code to do this.  First, modify
ruby/profiler/Profiler.C and Profiler.h to add a function to track the
read and write misses in which you can pass the processor ID.  To hook
this up to SLICC, you will also need to add a function to
ruby/slicc_interface/RubySlicc_Profiler_interface.[Ch] to access the
function you added to the Profiler object.  Finally add the same
definition to the RubySlicc_Profiler_interface.sm file in the protocols
directory.

Then in the SLICC protocol specification, you will need to call your new
function passing the "machineID" variable (which is of type MachineID)
when a miss occurs.  To extract a processor number (starting with P0) from
the MachineID in the C++ function, dereference the "num" field of
MachineID (like id.num).
