Hi Jos,
I'm pretty sure the parameter is the actual BTB size. If you look at
m5/encumbered/cpu/full/bpred.cc:1402, you'll see that the BranchPred is
created with btb_size / btb_assoc passed in for the number of sets
parameter. While it is actually the BTB size, there really should be
some check to make sure that the btb_size is evenly divisible by the
btb_assoc to ensure that you're actually getting the btb_size you set.

Hi,
The BranchPred parameter btb_size seems to imply that it is for setting the
total size of the BTB (similar to the size parameter for caches and memory), but
if I interpret the code correctly, this parameter actually stands for the number
of sets? If so, perhaps in future versions the name of the parameter should be
adjusted.
