[gem5-users] Set number of register file read and write ports

[pedro--- via gem5-users]

Hi,

I'm trying to check the influence of the number of read and write register file 
ports on the maximum IPC achieved by the OoO model. However, I could not find 
any parameter that models the number of register file ports. Is there any?

For example, in none of the methods chain: readIntRegOperand (dyn_inst.hh) -> 
readIntReg (cpu.hh) -> readIntReg (regfile.hh) the number of ports is verified. 

Could anyone confirm if gem5 OoO model assumes there will always be enough 
ports to feed all functional units?

Thank you.
