Re: [gem5-users] Invalid Program counter of Packet

[Nikos Nikoleris]

Hi Avais,

If I remember correctly, this is expected. Evictions, for example, won't
have a valid program counter.

Can anyone suggest, how can i get valid program counter.

For the packets you are getting invalid program counter, can you check is
it read or write packet?

Re: [gem5-users] multi-gem5

[Andreas Brokalakis]

Hi Biruk,

I am not sure exactly what you wish to accomplish. However the COSSIM
approach that I suggested uses gme5 nodes that are connected together
through a network simulator (OMNET++). As such you can do any network
topology you like. There is even a graphical user interface to setup
everything, so the entry effort is not that difficult. :)

You can find the online repository to download everything here:
https://github.com/ntampouratzis/COSSIM

Hope it helps!
Andreas
