Re: [Gems-users] Using Ruby without SIMICS

[Osvaldo Colavin <ocolavin@xxxxxxxxxxx>]

Is there a target in the makefile that enables the compilation of Ruby
standalone, or perhaps with the testers (but not simics or opal)?
Cheers,

Osvaldo

It should definitely be do-able with a modest amount of effort.

We already use Ruby as a standalone memory hierarchy when using the Tester
driver.  The main entry point is the Ruby sequencer
($GEMS/ruby/system/Sequencer.C) which acts as the processor interface.
Drivers issue requests to Ruby via Sequencer::makeRequest.  The Sequencer
calls hitCallback() on the drivers when the request has finished.

All the Simics/Ruby interface is in $GEMS/ruby/simics.  You can see where
the Sequencer::makeRequest() call is made in the SimicsProcessor.C

This is a quick response.  If you have more specific questions, do ask
them.
