Hmmmm, something is broken, I’ve been trying and nothing seems to work. I can’t dump a timing_cpu checkpoint, because reloading it causes M5 to crash on initialization, certain serialization elements are missing. When I dump an atomic cpu checkpoint of the same benchmark, I can load it, but the kernel immediately panics and crashes. Any ideas? Was checkpointing broken prior to 2.0b5?
Thanks, Geoff From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Geoffrey Blake Sent: Tuesday, March 25, 2008 8:31 PM To: 'M5 users mailing list' Subject: RE: [m5-users] Full System Checkpoints I’m pretty sure its loading the correct checkpoints. What is really odd is if I load the atomic CPU checkpoint with Atomic CPU, it still crashed with a page handler error. I’ll keep fiddling, perhaps the serialization routines are broken on my build. I’m using a version of M5 from the repository that is older than 2.0b5, I should probably pull again to get the new changes.

I dump the checkpoint using the m5 pseudo instruction from inside the application. The checkpoint though seems malformed. If I dump it out running with timing simple cpu, the checkpoint will not load, the simulator crashes with a fatal error saying it cannot read _status for system.cpuXX. I've tried making checkpoints using the atomic CPU, and they seem load fine, but immediately after starting to run once the checkpoint is loaded, the binary crashes with a kernel page handling error, perhaps due to the fact it does not save any ITB entries.
