d8a34a9745 mips-tlb-fix: check for alignment faults.\nMIPS was never updated to use 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. 2009-04-18 10:42:29 -04:00

e501e1af54 mips-syscall: mark with correct flag. \nMIPS was using wrong serialization flag on syscall instructions allowing O3 to handle SE mode syscalls incorrectly and speculate on instructions after a syscall 2009-04-18 10:42:29 -04:00

14808ecac9 o3, inorder: fix FS bug due to initializing ThreadState to Halted. 
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.

b146131d18 o3: handle fetch with no active threads correctly. 
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.

7617dcf736 ThreadState: initialize status to Halted in constructor. 
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).

48d4ca522a Update stats after elimination of Unallocated state. 
Somehow ending threads with halt() instead of deallocate()
reduces the squash count on o3 by 1 (and a few other
similarly trivial changes).

8882dc1283 Get rid of the Unallocated thread context state. 
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.

9b66e82897 configs: Allow M5_CPU2000 env var to set CPU2K binary path. 
It would be nice to have a more comprehensive mechanism
but this is a big improvement over manually editing the script.

15f0e44060 Very minor regression stats updates due top previous changeset. 
Setting dirty bit on swaps added a handful of writebacks in a
few of the longer-running SPARC_SE benchmarks.

6f787e3d36 stats: create an enable phase, and a prepare phase. 
Enable more or less takes the place of check, but also allows stats to
do some other configuration.  Prepare moves all of the code that readies
a stat for dumping into a separate function in preparation for supporting
serialization of certain pieces of statistics data.
While we're at it, clean up the visitor code and some of the python code.
