memory mode information now contained in system object
States are now running, draining, or drained. memory state information moved into system object system parameter is not fs only for cpus Implement drain() support in devices Update for drain() call that returns number of times drain_event->process() will be called Break O3 CPU! No sense in putting in a hack change that kevin is going to remove in a few minutes i imagine src/cpu/simple/atomic.cc: src/cpu/simple/atomic.hh: Since se mode has a system, allow access to it Verify that the atomic cpu is connected to an atomic system on resume src/cpu/simple/base.cc: Since se mode has a system, allow access to it src/cpu/simple/timing.cc: src/cpu/simple/timing.hh: Update for new drain() call that returns number of times drain_event->process() will be called and memory state being moved into the system Since se mode has a system, allow access to it Verify that the timing cpu is connected to an timing system on resume src/dev/ide_disk.cc: src/dev/io_device.cc: src/dev/io_device.hh: src/dev/ns_gige.cc: src/dev/ns_gige.hh: src/dev/pcidev.cc: src/dev/pcidev.hh: src/dev/sinic.cc: src/dev/sinic.hh: Implement drain() support in devices src/python/m5/config.py: Allow drain to return number of times drain_event->process() will be called. Normally 0 or 1 but things like O3 cpu or devices with multiple ports may want to call it many times src/python/m5/objects/BaseCPU.py: move system parameter out of fs to everyone src/sim/sim_object.cc: src/sim/sim_object.hh: States are now running, draining, or drained. memory state information moved into system object src/sim/system.cc: src/sim/system.hh: memory mode information now contained in system object --HG-- extra : convert_revision : 1389c77e66ee6d9710bf77b4306fb47e107b21cf
