e826d23a2e Packet: Add derived class FunctionalPacket to enable partial functional reads
This adds the derived class FunctionalPacket to fix a long standing
deficiency in the Packet class where it was unable to handle finding data to
partially satisfy a functional access.  Made this a derived class as
functional accesses are used only in certain contexts and to not add any
additional overhead to the existing Packet class.

bda1125e88 stats: fix Vector2d to display stats correctly when y_subname is not specified.
Vector2d stats with no y_subname were not displayed as the VectorPrint subname was not initialized correctly to reflect the empty field.

51aa7e4a03 sim: Enable sampling of run-time for code-sections marked using pseudo insts.
This patch adds a mechanism to collect run time samples for specific portions
of a benchmark, using work_begin and work_end pseudo instructions.It also enhances
the histogram stat to report geometric mean.

c94e5256d9 mem: Change DPRINTF prints more useful destination port number.

3f9e352de4 Base: Fixed shift amount in genrand() to work with large numbers
The previous version didn't work correctly with max integer values (2^31-1 for
32-bit, 2^63-1 for 64bit version), causing "shift" to become -1.  For smaller
numbers, it wouldn't have caused functional errors, but would have resulted in
more than necessary loops in the while loop.  Special-cased cases when (max + 1
== 0) to prevent the ceilLog2 functions from failing.

59b7cad3ec SWIG: Make gem5 compile and link with swig 2.0.4
To make gem5 compile and run with swig 2.0.4 a few minor fixes are
necessary, the fail label issues by swig must not be treated as an
error by gcc (tested with gcc 4.2.1), and the vector wrappers must
have SWIGPY_SLICE_ARG defined which happens in pycontainer.swg,
included through std_container.i. By adding the aforementioned include
to the vector wrappers everything seems to work.

c2dbfc1d6c MAC: Make gem5 compile and run on MacOSX 10.7.2
Adaptations to make gem5 compile and run on OSX 10.7.2, with a stock
gcc 4.2.1 and the remaining dependencies from macports, i.e. python
2.7,.2 swig 2.0.4, mercurial 2.0. The changes include an adaptation of
the SConstruct to handle non-library linker flags, and Darwin-specific
code to find the memory usage of gem5. A number of Ruby files relied
on ambigious uint (without the 32 suffix) which caused compilation
errors.

a88ec980a4 Config: Add an option of type 'choice' for cpu type
This patch adds a new option for cpu type. This option is of type 'choice'
which is similar to a C++ enum, except that it takes string values as
possible choices. Following options are being removed -- detailed, timing,
inorder.

daa4c7526a eventq: add a function for replacing head of the queue
This patch adds a function for replacing the event at the head of the queue
with another event. This helps in running a different set of events. Events
already scheduled can processed by replacing the original head event back.
This function has been specifically added to support cache warmup and
cooldown required for creating and restoring checkpoints.

bd23a37198 X86 TLB: Move a DPRINTF to its correct place
The DPRINTF for doing protection checks appears after the checks have been
carried out. It is possible that the function returns while the checks are
being carried, in which case the printf is missed out. This patch moves the
DPRINTF before the checks.

frame is stored out to the m5out/frames_*/ directory.  Specifiy the flag
"--frame-capture" when running configs/example/fs.py to enable this behavior.

61c14da751 O3: Remove hardcoded tgts_per_mshr in O3CPU.py.
There are two lines in O3CPU.py that set the dcache and icache
tgts_per_mshr to 20, ignoring any pre-configured value of tgts_per_mshr.
This patch removes these hardcoded lines from O3CPU.py and sets the default
L1 cache mshr targets to 20.
