- 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
