d9317dd348 Some more useful debugging info for kernel panic and die events
Increase the default number of CSHR's, we should really fix this or make it a parameter

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

501db90f2c Make changes so that coherence works on a timing bus for the top-level of caches.
This added a snoopResponse callback to the caches, and a NACK to requests.

cpu/memtest/memtest.cc:
    Modified to work with do_events:
    No multiple requests to the same block outstanding at the same time from the same tester
    Using false sharing, each tester does only 1 byte access using it's id as the blk offset
    Allow for cycles before signaling deadlock, with do events it can take time to complete (NACK/blocked bus)
cpu/memtest/memtest.hh:
    Updated to keep an id with each tester (used for address generation)
    Updated to keep a list of outstanding address to prevent multiple outstanding per tester
    //Should really look into doing store forwarding within the tester, then we can test more functionality

9023f5c96d - 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:

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

    call through the exec context to do the special binning
    stuff.
kern/kernel_stats.cc:
kern/kernel_stats.hh:

    the ignore function easily
sim/sim_object.hh:
    implement the ignore event stuff in the sim object.  This is a
    bit of a hack, but an easy place to put it.

c27139c701 start towards getting m5 endian compliant
base/inifile.cc:
    Added mac os support and fixed a bug, on error we need to exit the
    child process not return
base/intmath.hh:
    gcc on macos wanted a seperate function for the size_t type
base/loader/elf_object.cc:
    I'm not sure why this works under linux because it seems to return
    the wrong value.
base/stats/text.cc:
    added define/include for mac os x
cpu/exec_context.hh:
cpu/simple_cpu/simple_cpu.cc:
    added endian conversion code
dev/alpha_console.cc:
    rather than accessing a charecter array of varying size depending on
    the access, lets actually do this properly.
dev/alpha_console.hh:
    get rid of now nolonger used consoleData
dev/disk_image.cc:
    We have to byte swap the data is some cases, added function to do that
dev/ethertap.cc:
    added preproc directive for mac os

d53c6c168a Get software prefetching to work in full-system mode.
Mostly a matter of keeping prefetches to invalid addrs
from messing up VM IPRs.  Also discovered that wh64s were
not being treated as prefetches, when they really should be
(for the most part, anyway).

arch/alpha/alpha_memory.cc:
arch/alpha/alpha_memory.hh:
    - Get rid of intrlock flag for locking VM fault regs (a la EV5);
    instead, just don't update regs on VPTE loads (a la EV6).
    - Add NO_FAULT MemReq flag to indicate references that should not
    cause page faults (i.e., prefetches).
arch/alpha/ev5.cc:
    - Get rid of intrlock flag for locking VM fault regs (a la EV5);
    instead, just don't update regs on VPTE loads (a la EV6).
    - Add Fault trace flag.
arch/alpha/isa_desc:
    - Add NO_FAULT MemReq flag to indicate references that should not
    cause page faults (i.e., prefetches).
    - Mark wh64 as a "data prefetch" instruction so it gets controlled
    properly by the FullCPU data prefetch control switch.
    - Align wh64 EA in decoder so issue stage doesn't need to worry about it.
arch/alpha/isa_traits.hh:
    - Get rid of intrlock flag for locking VM fault regs (a la EV5);
    instead, just don't update regs on VPTE loads (a la EV6).
base/traceflags.py:
    - Add Fault trace flag.
cpu/simple_cpu/simple_cpu.hh:
    - Pass MemReq flags to writeHint() operation.
cpu/static_inst.hh:
    Update comment re: prefetches.

e7c7c92184 Tracing now works for upto 4 threads. Easy change to get it to work for more, but I don't have any test handy to test it.
cpu/trace/reader/m5_reader.cc:
    Add thread num.
cpu/trace/trace_cpu.cc:
    Increase thread count to 4, might want to make this a parameter (but it only really costs us storage).
