2009-07-10SPARC: 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
2009-07-08Registers: 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

2009-05-04scons: 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.

2009-04-21syscall: Resolve conflicts between m5threads and Gabe's recent SE changes.Steve Reinhardt
2009-04-21Commit 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.
2009-04-15Get 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.

2009-02-23stats: 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)

It's instantaneous and so it's somewhat bogus, but it's a first step.

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.
2008-12-04This patch pulls out the auxiliary vector struct from individual ISALisa Hsu
LiveProcesses to the base LiveProcess definition so anyone can use them.

2008-11-15syscalls: 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.
2008-11-10pseudo inst: Add rpns (read processor nanoseconds) instruction.Nathan Binkert
This instruction basically returns the number of nanoseconds that the CPU has been running.

2008-11-10python: 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.
2008-11-05Right now a single thread cpu 1 could get assigned context Id != 1, dependingLisa Hsu
on the order in which it's registered with the system. To make them match, here is a little change.
2008-11-02Add 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.
2008-11-02Make it so that all thread contexts are registered with the System, even inLisa 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.
2008-11-02make BaseCPU the provider of _cpuId, and cpuId() instead of being scatteredLisa 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.
