The topology file route seems easy.

Thanks a lot for your help.

 That makes things a lot easier. Thank you.

A follow up question :
Where should I look if I want to identify the specific Controller connected
to a NI. I would like to identify a NI's corresponding controller by a name
and a number, e.g. CPCntrl0, L3Cntrl1 etc.

[gem5-dev] Garnet Network Interface connection to Protocol Controllers

[Arun Mishra via gem5-dev]

Hi All,

In Garnet, is a single Network Interface object (NI) connected to a single
Protocol Controller (e.g. Directory Controller, Cache Ctrl, Core pair Ctrl)
or is connection to multiple controllers possible ?

I am asking this because I need to collect some controller specific network
stats and I want to know if there is a way to separate out the stats based
on the NI it is connected with. Otherwise, is there a better way of
collecting per controller network stats ?

Thank You,
Arun Mishra
