Acutally we need the default setting for protocols that do not need or set the coreid parameter. I modified the patch to set the default to 99 and I added a comment to make it clear that is a dummy value that should be overwritten. > On Nov. 13, 2015, 11:03 p.m., Joel Hestness wrote: > > src/mem/ruby/slicc_interface/RubySlicc_ComponentMapping.hh, line 128 > > <http://reviews.gem5.org/r/3189/diff/1/?file=51133#file51133line128> > > > > This function is functionally identical to createMachineID. Why add a > > separate function? The function MachineTypeAndNodeIDToMachineID actually predates the function createMachineID. The fact that this function was separately introduced by two different set of folks highlights why we need to get this patch checked in soon. I have updated the patch to use createMachineID. > On Nov. 13, 2015, 11:03 p.m., Joel Hestness wrote: > > src/mem/ruby/structures/CacheMemory.hh, line 187 > > <http://reviews.gem5.org/r/3189/diff/1/?file=51135#file51135line187> > > > > Couple things: > > 1) I see that initializing variables like this in the class declaration > > is new C++11 functionality.

I will not modify the rest of this patch because this code will be fixed in the multi-instance Ruby patches.

The multi-instance ruby patches fix/remove this code. There is no need to fix it here. - Brad ----------------------------------------------------------- This is an automatically generated e-mail.
