2009-09-15	inorder-alpha-fs: edit inorder model to compile FS mode	Korey Sewell

2009-07-08	Get rid of the unused get(Data\|Inst)Asid and (inst\|data)Asid functions.	Gabe Black

2009-07-08	Registers: Eliminate the ISA defined integer register file.	Gabe Black

2009-07-08	Registers: Eliminate the ISA defined floating point register file.	Gabe Black

2009-07-08	Registers: Get rid of the float register width parameter.	Gabe Black

2009-07-08	Registers: 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.
2009-06-04	types: clean up types, especially signed vs unsigned	Nathan Binkert

2009-05-26	types: add a type for thread IDs and try to use it everywhere	Nathan Binkert

2009-05-12	inorder-tlb-cunit: merge the TLB as implicit to any memory access	Korey 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. * * *
2009-05-12	inorder-tlb: squash insts in TLB correctly	Korey Sewell
	TLB had a bug where if it was stalled and waiting , it would not squash all instructions older than squashed instruction correctly * * *
2009-05-12	inorder-stc: update interface to handle store conditionals	Korey Sewell

2009-05-12	inorder-mem: skeleton support for prefetch/writehints	Korey Sewell

2009-05-12	inorder-unified-tlb: use unified TLB instead of old TLB model	Korey Sewell

2009-05-12	inorder-alpha-port: initial inorder support of ALPHA	Korey 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.)
2009-04-17	o3, 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.
2009-04-15	ThreadState: 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).
2009-03-04	InOrderCPU: Clean up Constructors to initialize variables correctly (i.e. in ↵	Korey Sewell
	a way for the compiler to play nice)
2009-03-04	Remove unused functions/comments cluttering up the code.	Korey Sewell

2009-03-04	make handling of interstage buffers (i.e. StageQueues) more consistent: ↵	Korey Sewell
	(1)number from 0-n, not 1-n+1, (2) always check nextStageValid before a stageNum+1 and prevStageValid for a stageNum-1 reference (3) add skidSize() to get StageQueue size for all threads
2009-03-04	Give TimeBuffer an ID that can be set. Necessary because InOrder uses ↵	Korey Sewell
	generic stages so w/o an ID there is no way to differentiate buffers when debugging
2009-03-04	use numCycles instead of simTicks to determine CPI stat in InOrder	Korey Sewell

2009-02-27	Processes: Make getting and setting system call arguments part of a process ↵	Gabe Black
	object.
2009-02-10	InOrder: Import new inorder CPU model from MIPS.	Korey Sewell
	This model currently only works in MIPS_SE mode, so it will take some effort to clean it up and make it generally useful. Hopefully people are willing to help make that happen!
