Thanks a lot. I hope that the sparc64 support in gem5 stays around indefinitely because as far as I know, gem5 is the only open source emulator capable of emulating sun4v and not requiring either a SPARC machine or Solaris.
So do I - gem5 has been a big help during my work trying to get NetBSD running on sun4v.
Probably also very usefull for the other BSDs as well.
The issue preventing the unmodified version of HelenOS functioning properly is that for some reason gem5 panics on accesses to the TickCompare register. Which also means that the following fix seems incomplete: changeset: 11102:c77f3a9e59bb user: Palle Lyckegaard <[email protected]> date: Tue Sep 15 08:14:07 2015 -0500 summary: sparc: writing to tick_cmpr should not cause a panic
The NetBSD porting effort hasn't reached a state yet where this issue has popped up yet, so I guess my fix is incomplete. Sorry for that - will have to work on this when I get to the isssue.
