2009-10-27POWER: Add support for the Power ISATimothy M. Jones
This adds support for the 32-bit, big endian Power ISA. This supports both integer and floating point instructions based on the Power ISA Book I v2.06.

2009-09-26O3: Add flag to control whether faulting instructions are traced.Steve Reinhardt
When enabled, faulting instructions appear in the trace twice (once when they fault and again when they're re-executed). This flag is set by the Exec compound flag for backwards compatibility.
2009-09-26O3: Mark fetch stage as active if it faults.Steve Reinhardt
Otherwise if the rest of the pipeline is idle then fault will never propagate to commit to be handled, causing CPU to deadlock.

2009-09-22python: Move more code into m5.util allow SCons to use that code.Nathan Binkert
Get rid of misc.py and just stick misc things in __init__.py Move utility functions out of SCons files and into m5.util Move utility type stuff from m5/__init__.py to m5/util/__init__.py Remove buildEnv from m5 and allow access only from m5.defines Rename AddToPath to addToPath while we're moving it to m5.util Rename read_command to readCommand while we're moving it Rename compare_versions to compareVersions while we're moving it. --HG-- rename : src/python/m5/convert.py => src/python/m5/util/convert.py rename : src/python/m5/smartdict.py => src/python/m5/util/smartdict.py
2009-09-17inorder-mdu: multiplier latency fixKorey Sewell
mdu was workign incorrectly for 4+ latency due to incorrectly assuming multiply was finished the next stage
2009-09-16inorder-smt: remove hardcoded valuesSoumyaroop Roy
allows for the 2T hello world example to work in inorder model
2009-09-15inorder-alpha-fs: edit inorder model to compile FS modeKorey Sewell
2009-09-01SCons fix to always make MemTest objectPolina Dudnik
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.
2009-07-29Simple CPU: Make the simple CPU handle the IntRegs trace flag.Gabe Black
2009-07-27ARM: Make native trace print out what instruction caused an error.Gabe Black

2009-07-08Registers: Add a registers.hh file as an ISA switched header.Gabe Black
This file is for register indices, Num* constants, and register types. copyRegs and copyMiscRegs were moved to utility.hh and utility.cc. --HG-- rename : src/arch/alpha/regfile.hh => src/arch/alpha/registers.hh rename : src/arch/arm/regfile.hh => src/arch/arm/registers.hh rename : src/arch/mips/regfile.hh => src/arch/mips/registers.hh rename : src/arch/sparc/regfile.hh => src/arch/sparc/registers.hh rename : src/arch/x86/regfile.hh => src/arch/x86/registers.hh

2009-07-08Registers: Add an ISA object which replaces the MiscRegFile.Gabe Black
This object encapsulates (or will eventually) the identity and characteristics of the ISA in the CPU.

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-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
