2009-04-18o3-mips-regress: add hello word regression.Korey Sewell
2009-04-18mips-tlb-fix: check for alignment faults.\nMIPS was never updated to use ↵Korey Sewell
TLBS correcty in SE mode. The error was forwarding translations directly to pageTable. The TLB should check for alignment faults at bare minimum here but in the long run we should be using TLBs in SE mode for MIPS.
2009-04-18mips-syscall: mark with correct flag. \nMIPS was using wrong serialization ↵Korey Sewell
flag on syscall instructions allowing O3 to handle SE mode syscalls incorrectly and speculate on instructions after a syscall
2009-04-18o3-delay-slot-bpred: fix decode stage handling of uncdtl. branches.\n decode ↵Korey Sewell
stage was not setting the predicted PC correctly or passing that information back to fetch correctly

2009-04-17o3, inorder: fix FS bug due to initializing ThreadState to Halted.Steve Reinhardt
For some reason o3 FS init() only called initCPU if the thread state was Suspended, which was no longer the case. There's no apparent reason to check, so I whacked the test completely rather than changing the check to Halted. The inorder init() was also updated to be symmetric, though the previous code was just a fancy no-op.
2009-04-15o3: handle fetch with no active threads correctly.Steve Reinhardt
This situation can arise now on the first fetch cycle after the last active thread is halted. It seems easy enough to deal with when it happens rather than trying to avoid it.
2009-04-15o3: fix {read,set}ArchFloatReg* functions.Steve Reinhardt
Register indices were not being calculated properly.
2009-04-15ThreadState: initialize status to Halted in constructor.Steve Reinhardt
This provides a common initial status for all threads independent of CPU model (unlike the prior situation where CPUs initialized threads to inconsistent states). This mostly matters for SE mode; in FS mode, ISA-specific startupCPU() methods generally handle boot-time initialization of thread contexts (since the right thing to do is ISA-dependent).
2009-04-15Update stats after elimination of Unallocated state.Steve Reinhardt
Somehow ending threads with halt() instead of deallocate() reduces the squash count on o3 by 1 (and a few other similarly trivial changes).
2009-04-15Get rid of the Unallocated thread context state.Steve Reinhardt
Basically merge it in with Halted. Also had to get rid of a few other functions that called ThreadContext::deallocate(), including: - InOrderCPU's setThreadRescheduleCondition. - ThreadContext::exit(). This function was there to avoid terminating simulation when one thread out of a multi-thread workload exits, but we need to find a better (non-cpu-centric) way.
2009-04-15configs: Allow M5_CPU2000 env var to set CPU2K binary path.Steve Reinhardt
It would be nice to have a more comprehensive mechanism but this is a big improvement over manually editing the script.

2009-03-16Very minor regression stats updates due top previous changeset.Steve Reinhardt
Setting dirty bit on swaps added a handful of writebacks in a few of the longer-running SPARC_SE benchmarks.
