Andreas Sandberg e5dca84c3f config: Move CPU handover logic to m5.switchCpus() ... CPU switching consists of the following steps: 1. Drain the system 2. Switch out old CPUs (cpu.switchOut()) 3. Change the system timing mode to the mode the new CPUs require 4. Flush caches if switching to hardware virtualization 5. Inform new CPUs of the handover (cpu.takeOverFrom()) 6. Resume the system m5.switchCpus() previously only did step 2 & 5. Since information about the new processors' memory system requirements is now exposed, do all of the steps above. This patch adds automatic memory system switching and flush (if needed) to switchCpus(). Additionally, it adds optional draining to switchCpus(). This has the following implications: * changeToTiming and changeToAtomic are no longer needed, so they have been removed. * changeMemoryMode is only used internally, so it is has been renamed to be private. * switchCpus requires a reference to the system containing the CPUs as its first parameter. WARNING: This changeset breaks compatibility with existing configuration scripts since it changes the signature of m5.switchCpus().		2013-02-15 17:40:08 -05:00
