Hi Uday,
Sure. In that case I'd say add another unique value and (re)use that for all
these requests. You can simply ask the system for one on initialisation. There
is no functional need for the masterID. It's only used for the book keeping.

Subject: Re: [gem5-users] masterID for snooping
Hi Andreas,
What you say is true for an interconnect-like module that uses a “normal”
request to create a “snoop” request.
But, in my case, I have to create a snoop request from scratch because this
snoop request originally is from an interconnect-like module in a different bus
protocol domain. Can this scenario be supported?
Thanks,
Uday

Hi Uday,
If you need to send requests I would imagine you want a master port. A snoop
request would typically be created from a "normal" request and thus copy its
master id.

Subject: [gem5-users] masterID for snooping
Hi,
I have a module (derived from SimpleMemory) which has an instance of type
‘SlavePort’. I need to call sendTimingSnoopReq( PacketPtr ) on this port. For
this I have to first create a Request and then Packet.
Request() constructor needs a mastered. I understand that typically this is
obtained at init time by calling getMasterID from System. But, I have
SimpleMemoryParams which doesn’t have handle to System. How do I obtain
masterID for sending a snoop Request?
Thanks,
Uday
