- 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
