To make it easier to have a discussion about this proposed API, I copied it
into a document over here:

Please take a look when you have a chance.

Hello again folks. I'm tempted to write up a doc which describes my
thoughts on this, but for the sake of expediency I'm just going to send a
"quick" email for now. (edit: This got pretty long. Maybe I should have put
it in a doc. Too late now, maybe later?)
TLM DMI socket API:

I think gem5 would benefit from it for the same reason SystemC simulations
do, namely speeding up simulations when doing fast forwarding (perhaps with
a binary translating CPU... hypothetically...). It would also be very nice
to enable software development for not-yet-existing hardware that has
Hi Gabe,
one of the main reasons for DMI is to speedup simulations, similar to the
temporal decoupling in TLM LT or debug transport in order to make the
boot-loading. AFAIK DMI is mainly used in virtual platforms that target
software development and not hardware architecture design space

Hi folks. TLM is a communication protocol/mechanism built on top of
systemc. It supports a mechanism called DMI which stands for direct memory
interface. The idea is that an entity sending a request into the system can
ask if the target can give it a pointer it can use to directly access that
