Use a setBlocked call to tell the bus it should block
New technique for sampling and switchover:
1) Sampler switchover event happens
2) All cpus in the current phase of sampling associated with this sampler are signaled to switchover
3) Each cpu drains it's pipe of things being executed (stops fetching and waits for empty pipe)
4) Once the pipe is empty the cpu calls back to the sampler to signal it has finished, and moves into the switchedout state (continues not to fetch)
5) The sampler collects all the signals, once all cpus are drained it calls the new cpu's in the next phase to takeover from the correct cpu
6) The statistics are reset and the next switchover time is calculated from this point

brediction unit.
cpu/beta_cpu/fetch_impl.hh:
Add in branch prediction. Changed how fetch checks inputs and its
current state to make for easier logic.
cpu/beta_cpu/free_list.cc:
Changed int regs and float regs to logically use one flat namespace.
Future change will be moving them to a single scoreboard to conserve
space.
cpu/beta_cpu/free_list.hh:
Mostly debugging statements. Might be removed for performance in future.
cpu/beta_cpu/full_cpu.cc:
Added in some debugging statements. Updated BaseFullCPU to take
a params object.
cpu/beta_cpu/full_cpu.hh:
Added params class within BaseCPU that other param classes will be
able to inherit from. Updated typedefs to reflect change in location
of time buffer structs and ref counted DynInst.
cpu/beta_cpu/iew.hh:
Updated typedefs to reflect change in location of time buffer structs
and use of ref counted DynInsts.
cpu/beta_cpu/iew_impl.hh:
Added in load store queue, updated iew to be able to execute non-
speculative instructions, instead of having them execute in commit.
cpu/beta_cpu/inst_queue.hh:
Updated change to ref counted DynInsts. Changed inst queue to hold
non-speculative instructions as well, which are issued only when
commit signals backwards that a nonspeculative instruction is at
the head of the ROB.
cpu/beta_cpu/inst_queue_impl.hh:
Updated to allow for non-speculative instructions to be in the inst
queue. Also added some debug functions.
cpu/beta_cpu/regfile.hh:
Added debugging statements, changed formatting.
cpu/beta_cpu/rename.hh:
Updated typedefs, added some functions to clean up code.
cpu/beta_cpu/rename_impl.hh:
Moved some code into functions to make it easier to read.
cpu/beta_cpu/rename_map.cc:
Changed int and float reg behavior to use a single flat namespace. In
the future, the rename maps can be combined to a single rename map to
save space.
cpu/beta_cpu/rename_map.hh:
Added destructor.
cpu/beta_cpu/rob.hh:
Updated it with change from DynInst to ref counted DynInst.
cpu/beta_cpu/rob_impl.hh:
Formatting, updated to use ref counted DynInst.
cpu/static_inst.hh:
Updated forward declaration for AlphaDynInst now that it is templated.

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.

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

FnEvents only need to know the bin
create the Idle start event to find the PCBB of the idle
process when it starts.
