Peter Grehan <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected] --- Comment #3 from Peter Grehan <[email protected]> --- I looked into this a while back: there are 2 issues - DFly is accessing memory beyond 4G when there is < 4G configured. This appears to be an array access in sys/platform/pc64/x86_64/mptable.c:mptable_search_sig() However, in PC-land this is allowed and accesses beyond the end of RAM will return 0xff's on a read. - bhyve does return 0xff's for reads beyond the end of memory, but doesn't implement that particular instruction (cmpl $0x5f504d5f,(%rax,%rcx,4)) Rather than having to implement that instruction for such an edge condition, I'll try and resurrect the patch I once had (unfortunately lost) and get the fix into DFly. -- You are receiving this mail because: You are the assignee for the bug. _______________________________________________ [email protected] mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-virtualization To unsubscribe, send any mail to "[email protected]"
