Sorry, that's not what this patch is meant to do; honestly, I haven't even put any thought into what you mentioned. The build is per-protocol still. The goal here is to have multiple ruby systems that can invoke the same protocol. Currently, that's not possible, which means that it's not possible to simulate multiple "systems" within a single gem5 invocation. - Brandon ----------------------------------------------------------- This is an automatically generated e-mail.
