2009-08-23Atomic CPU: Respect the NO_ACCESS request flag.Gabe Black
2009-08-01Fix setting of INST_FETCH flag for O3 CPU.Steve Reinhardt
It's still broken in inorder. Also enhance DPRINTFs in cache and physical memory so we can see more easily whether it's getting set or not.

2009-05-12cpus: add InOrderCPU to default buildKorey Sewell
regressions need this so they build the model
2009-05-12inorder-resources: delete eventsKorey Sewell
make sure unrecognized events in the resource pool are deleted and also delete resource events in destructor
2009-05-12inorder-tlb-cunit: merge the TLB as implicit to any memory accessKorey Sewell
TLBUnit no longer used and we also get rid of memAccSize and memAccFlags functions added to ISA and StaticInst since TLB is not a separate resource to acquire. Instead, TLB access is done before any read/write to memory and the result is checked before it's sent out to memory. * * *
2009-05-12inorder-tlb: squash insts in TLB correctlyKorey Sewell
TLB had a bug where if it was stalled and waiting , it would not squash all instructions older than squashed instruction correctly * * *
2009-05-12inorder-faults: ignore unalign translation faults for prefetchesKorey Sewell
2009-05-12inorder-stc: update interface to handle store conditionalsKorey Sewell
2009-05-12inorder-float: Fix storage of FP resultsKorey Sewell
inorder was incorrectly storing FP values and confusing the integer/fp storage view of floating point operations. A big issue was knowing trying to infer when were doing single or double precision access because this lets you know the size of value to store (32-64 bits). This isnt exactly straightforward since alpha uses all 64-bit regs while mips/sparc uses a dual-reg view. by getting this value from the actual floating point register file, the model can figure out what it needs to store
2009-05-12inorder-fetch: update model to use predecoderKorey Sewell
2009-05-12inorder-mem: clean up allocation/deletion of requests/packetsKorey Sewell
* * *
2009-05-12inorder-mem: skeleton support for prefetch/writehintsKorey Sewell
2009-05-12inorder-o3: allow both to compile togetherKorey Sewell
allow InOrder and O3CPU to be compiled at the same time: need to make branch prediction filed shared by both models
2009-05-12inorder-unified-tlb: use unified TLB instead of old TLB modelKorey Sewell
2009-05-12inorder-miscregs: Fix indexing for misc. reg operands and update ↵Korey Sewell
result-types for better tracing of these types of values
2009-05-12inorder/alpha-isa: create eaComp object visible to StaticInst through ISAKorey Sewell
Remove subinstructions eaComp/memAcc since unused in CPU Models. Instead, create eaComp that is visible from StaticInst object. Gives InOrder model capability of generating address without actually initiating access * * *
2009-05-12inorder-bpred: edits to handle non-delay-slot ISAsKorey Sewell
Changes so that InOrder can work for a non-delay-slot ISA like Alpha. Typically, changes have to do with handling misspeculated branches at different points in pipeline
2009-05-12inorder-alpha-port: initial inorder support of ALPHAKorey Sewell
Edit AlphaISA to support the inorder model. Mostly alternate constructor functions and also a few skeleton multithreaded support functions * * * Remove namespace from header file. Causes compiler issues that are hard to find * * * Separate the TLB from the CPU and allow it to live in the TLBUnit resource. Give CPU accessor functions for access and also bind at construction time * * * Expose memory access size and flags through instruction object (temporarily memAccSize and memFlags to get TLB stuff working.)
2009-05-05cpus: fix cpu progress eventKorey Sewell
this was double scheduling itself (once in constructor and once in cpu code). also add support for stopping / starting progress events through repeatEvent flag and also changing the interval of the progress event as well
2009-04-21arm: Unify the ARM tlb. We forgot about this when we did the rest.Nathan Binkert
This code compiles, but there are no tests still
2009-04-20request: rename INST_READ to INST_FETCH.Steve Reinhardt
2009-04-19Mem: Change isLlsc to isLLSC.Gabe Black
2009-04-19CPUs: Make the atomic CPU support locked memory accesses.Gabe Black
2009-04-19Memory: Rename LOCKED for load locked store conditional to LLSC.Gabe Black
2009-04-19CPU: If the simple CPU is already idle, just return from suspendContext, ↵Gabe Black
don't assert.
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).
2009-04-15Get 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.
