2009-07-10	SPARC: Set up a lookup table for integer register flattening.	Gabe Black
	Using a look up table changed the run time of the SPARC_FS solaris boot regression from: real 14m45.951s user 13m57.528s sys 0m3.452s to: real 12m19.777s user 12m2.685s sys 0m2.420s
2009-07-08	Registers: 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
2009-06-04	types: clean up types, especially signed vs unsigned	Nathan Binkert

2009-06-04	style: cleanup style	Nathan Binkert

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

2009-05-17	includes: sort includes again	Nathan Binkert

2009-05-17	includes: use base/types.hh not inttypes.h or stdint.h	Nathan Binkert

2009-05-17	types: Move stuff for global types into src/base/types.hh	Nathan Binkert
	--HG-- rename : src/sim/host.hh => src/base/types.hh
2009-05-04	scons: re-work the *Source functions to take more information.	Nathan Binkert
	Start by turning all of the *Source functions into classes so we can do more calculations and more easily collect the data we need. Add parameters to the new classes for indicating what sorts of flags the objects should be compiled with so we can allow certain files to be compiled without Werror for example.
2009-04-24	SPARC: Tighten up the clone system call and SPARCs copyRegs.	Gabe Black

2009-04-21	pseudo: only include kernel stats if FULL_SYSTEM.	Nathan Binkert

2009-04-21	syscall_emul: style fixes (mostly wrapping overly long lines)	Steve Reinhardt

2009-04-21	syscall: Resolve conflicts between m5threads and Gabe's recent SE changes.	Steve Reinhardt

2009-04-21	Commit m5threads package.	Daniel Sanchez
	This patch adds limited multithreading support in syscall-emulation mode, by using the clone system call. The clone system call works for Alpha, SPARC and x86, and multithreaded applications run correctly in Alpha and SPARC.
2009-04-15	Get 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.
2009-04-08	tlb: More fixing of unified TLB	Nathan Binkert

2009-04-08	tlb: Don't separate the TLB classes into an instruction TLB and a data TLB	Gabe Black

2009-03-05	stats: Fix all stats usages to deal with template fixes	Nathan Binkert

2009-03-05	serialize: Allow floats and doubles to be serialized	Nathan Binkert

2009-02-27	Processes: Make getting and setting system call arguments part of a process ↵	Gabe Black
	object.
2009-02-27	X86: Add a class to support 32 bit x86 linux process.	Gabe Black

2009-02-26	CPA: Add new object for gathering critical path annotations.	Ali Saidi

2009-02-25	CPU: Implement translateTiming which defers to translateAtomic, and convert ↵	Gabe Black
	the timing simple CPU to use it.
2009-02-25	ISA: Replace the translate functions in the TLBs with translateAtomic.	Gabe Black

2009-02-23	stats: cleanup static stats to make startup work.	Nathan Binkert
	This is mainly to allow the unit test to run without requiring the standard M5 stats from being initialized (e.g. sim_seconds, sim_ticks, host_seconds)
2009-02-23	debug: Move debug_break into src/base	Nathan Binkert

2009-02-16	sycalls: implement mremap() and add DATA flag for getrlimit(). mremap has ↵	Lisa Hsu
	been tested on Alpha, compiles for the rest but not tested. I don't see why it wouldn't work though.
2009-02-15	X86: Make the loader recognize 32 bit x86 processes.	Gabe Black

2009-01-30	Errors: Use the correct panic/warn/fatal/info message in some places.	Ali Saidi

2009-01-29	Fix typo	Nathan Binkert

2009-01-24	pseudo inst: Add new wake cpu instruction for sending a message to wake a cpu.	Nathan Binkert
	It's instantaneous and so it's somewhat bogus, but it's a first step.
2009-01-19	python: Rework how things are imported	Nathan Binkert

2009-01-17	Fix issue 326: glibc non-deterministic because it reads /proc	Ali Saidi

2009-01-06	Tracing: Make tracing aware of macro and micro ops.	Gabe Black

2008-12-17	Make Alpha pseudo-insts available from SE mode.	Steve Reinhardt

2008-12-08	eventq: Add some debugging code to the eventq.	Nathan Binkert

2008-12-07	imported patch aux-fix.patch	Lisa Hsu

2008-12-06	eventq: use the flags data structure	Nathan Binkert

2008-12-06	eventq: move virtual function definitiions to the .cc file.	Nathan Binkert

2008-12-05	This brings M5 closer to modernity - the kernel being advertised is newer so ↵	Lisa Hsu
	it won't die on binaries compiled with newer glibc's, and enables use of TLS-toolchain built binaries for ALPHA_SE by putting auxiliary vectors on the stack. There are some comments in the code to help. Finally, stats changes for ALPHA are from slight perturbations to the initial stack frame, all minimal diffs.
2008-12-04	This patch pulls out the auxiliary vector struct from individual ISA	Lisa Hsu
	LiveProcesses to the base LiveProcess definition so anyone can use them.
2008-11-20	Assume files w/o obvious OS are Linux (with warning)	Steve Reinhardt
	instead of giving a fatal error.
2008-11-15	syscalls: fix latent brk/obreak bug.	Steve Reinhardt
	Bogus calls to ChunkGenerator with negative size were triggering a new assertion that was added there. Also did a little renaming and cleanup in the process.
2008-11-10	pseudo inst: Add rpns (read processor nanoseconds) instruction.	Nathan Binkert
	This instruction basically returns the number of nanoseconds that the CPU has been running.
2008-11-10	clean: Move some stuff from the hh file to the cc file.	Nathan Binkert

2008-11-10	python: Fix the reference counting for python events placed on the eventq.	Nathan Binkert
	We need to add a reference when an object is put on the C++ queue, and remove a reference when the object is removed from the queue. This was not happening before and caused a memory problem.
2008-11-05	Right now a single thread cpu 1 could get assigned context Id != 1, depending	Lisa Hsu
	on the order in which it's registered with the system. To make them match, here is a little change.
2008-11-02	Add in Context IDs to the simulator. From now on, cpuId is almost never used,	Lisa Hsu
	the primary identifier for a hardware context should be contextId(). The concept of threads within a CPU remains, in the form of threadId() because sometimes you need to know which context within a cpu to manipulate.
2008-11-02	Make it so that all thread contexts are registered with the System, even in	Lisa Hsu
	SE. Process still keeps track of the tc's it owns, but registration occurs with the System, this eases the way for system-wide context Ids based on registration.
2008-11-02	make BaseCPU the provider of _cpuId, and cpuId() instead of being scattered	Lisa Hsu
	across the subclasses. generally make it so that member data is _cpuId and accessor functions are cpuId(). The ID val comes from the python (default -1 if none provided), and if it is -1, the index of cpuList will be given. this has passed util/regress quick and se.py -n4 and fs.py -n4 as well as standard switch.
