Hi Dave, The PMU isn't currently implemented. It's something we've been working on at ARM, but it's not complete yet.

One more question, does GEM5 also simulate PMU(performance monitor unit)? regards, Dave On Tue, May 29, 2012 at 10:37 AM, Ali Saidi <ali.sa...@arm.com<mailto:ali.sa...@arm.com>> wrote: This looks like you're trying to run a semi-hosted binary (the svc with #22 as the call number being heap info), not a syscall emulation binary. gem5 doesn't currently support executing semi-hosted code, but if you compile a static linux executable you can run that. As another option, if you have a bare metal tool flow, you can run that too.
