- Clean up and factor out all of the binning code into a single place so it's easier to work with. - Add support for binning kernel/user/idle time separately from lisa's binning stuff, but make the two compatible. - KernelStats used to directly implement the pImpl idiom, but it makes more sense to just remove the level of indirection and make the exec context have a pointer to the stats. - Factor common code out of LinuxSystem and Tru64System and put it into the System base class. While doing that, make all constructors take a pointer to a parameter struct instead of naming the parameters individually to make it much easier to add parameters to these classes. SConscript: Move the function tracking and binning stuff around. arch/alpha/ev5.cc: kernelStats is now a pointer arch/alpha/pseudo_inst.cc: kernelStats is now a pointer the parameters to the system have been moved into their own struct base/trace.hh: provide a little functor class for wrapping a string that can allow you to define name() in any scope very simply for use with DPRINTF cpu/base_cpu.cc: New order of arguments for consistency. cpu/exec_context.cc: kernelStats no longer has the level of indirection in it, execContext has the indirection now. so, kernelStats is a pointer. We also need a pointer to the kernelBinning stuff from the system and we need to figure out if we want to do binning or not. Move a whole bunch of code into kern_binning.cc so it's all in the same place. cpu/exec_context.hh: We want pointers to the kernel binning/stats stuff and we'll have the exec_context and system have the level of indirection instead of having the extra layer in the kernel stats class. cpu/simple_cpu/simple_cpu.cc: call through the exec context to do the special binning stuff. kern/kernel_stats.cc: kern/kernel_stats.hh: Re-organize the stats stuff and remove the level of indirection (that was there to simplify building) and move the binning stuff into its own class/file. kern/linux/linux_system.cc: kern/linux/linux_system.hh: kern/tru64/tru64_system.cc: kern/tru64/tru64_system.hh: sim/system.cc: sim/system.hh: move lots of common system code into the base system class so that it can be shared between linux, tru64, and whatever else we decide to support in the future. Make the constructor take a pointer to a parameter struct so that it is easier to pass parameters to the parent. kern/system_events.cc: move the majority of the binning code into the Kernel::Binning class in the kern_binning file kern/system_events.hh: FnEvents only need to know the bin create the Idle start event to find the PCBB of the idle process when it starts. kern/tru64/tru64_events.cc: memCtrl -> memctrl sim/process.cc: sim/process.hh: re-order args for consistency --HG-- extra : convert_revision : 86cb39738c41fcd680f2aad125c9dde000227b2b

Put everything as globals in the Statistics::Database namespace. allocate unique ids for all stats. directly implement the check routine and get rid of the various dumping routines since they're now in separate files. make sure that no two stats have the same name clean up some loops base/statistics.hh: major changes to the statistics package again lots of code was factored out of statistics.hh into several separate files in base/stats/ (this will continue) There are now two Stat package types Result and Counter that are specified to allow the user to keep the counted type separate from the result type. They are currently both doubles but that's an experiment. There is no more per stat ability to set the type. Statistics::Counter is not the same as Counter! Implement a visitor for statistics output so that new output types can be implemented independently from the stats package itself. Add a unique id to each stat so that it can be used to keep track of stats more simply. This number can also be used in debugging problems with stats. Tweak the bucket size stuff a bit to make it work better. fixed VectorDist size bug cpu/memtest/memtest.cc: Fix up for changes in stats package Don't use value() since it doesn't work with binning. If you want a number as a stat, and to use it in the program itself, you really want two separate variables, one that's a stat, and one that's not. cpu/memtest/memtest.hh: Fix up for changes in stats package test/Makefile: Try to build stuff now that directories matter test/stattest.cc: test all new output types choose which one with command line options --HG-- extra : convert_revision : e3a3f5f0828c67c0e2de415d936ad240adaddc89

Changed the AlphaISA namespace reference to TheISA. Changed arch/alpha/vtophys.hh to targetarch/vtophys.hh, since this file is now for all architectures.

Steps towards setting up the infrastructure to allow the new CPU model to work in full system mode. The major change is renaming the old ExecContext to CPUExecContext, and creating two new classes, ExecContext (an abstract class), and ProxyExecContext (a templated class that derives from ExecContext). Code outside of the CPU continues to use ExecContext as normal (other than not being able to access variables within the XC). The CPU uses the CPUExecContext, or however else it stores its own state. It then creates a ProxyExecContext, templated on the class used to hold its state. This proxy is passed to any code outside of the CPU that needs to access the XC. This allows code outside of the CPU to use the ExecContext interface to access any state needed, without knowledge of how that state is laid out. Note that these changes will not compile without the accompanying revision to automatically rename the shadow registers. SConscript: Include new file, cpu_exec_context.cc. arch/alpha/alpha_linux_process.cc: arch/alpha/alpha_memory.cc: arch/alpha/alpha_tru64_process.cc: arch/alpha/arguments.cc: arch/alpha/isa/decoder.isa: arch/alpha/stacktrace.cc: arch/alpha/vtophys.cc: base/remote_gdb.cc: cpu/intr_control.cc: Avoid directly accessing objects within the XC. arch/alpha/ev5.cc: Avoid directly accessing objects within the XC. KernelStats have been moved to the BaseCPU instead of the XC. arch/alpha/isa_traits.hh: Remove clearIprs(). It wasn't used very often and it did not work well with the proxy ExecContext. cpu/base.cc: Place kernel stats within the BaseCPU instead of the ExecContext. For now comment out the profiling code sampling until its exact location is decided upon. cpu/base.hh: Kernel stats are now in the BaseCPU instead of the ExecContext. cpu/base_dyn_inst.cc: cpu/base_dyn_inst.hh: cpu/memtest/memtest.cc: cpu/memtest/memtest.hh: Changes to support rename of old ExecContext to CPUExecContext.

This is used by the old CPU models to store any necessary architectural state. Also include the ProxyExecContext, which is used to access the CPUExecContext's state in code outside of the CPU. Remove kernel stats from the ExecContext. sim/pseudo_inst.cc: Kernel stats now live within the CPU. Avoid accessing objects directly within the XC. --HG-- rename : cpu/exec_context.cc => cpu/cpu_exec_context.cc rename : cpu/exec_context.hh => cpu/cpu_exec_context.hh extra : convert_revision : a75393a8945c80cca225b5e9d9c22a16609efb85
