36373fa465 Virtualized SINIC fixes
dev/pktfifo.hh:
    we can't modify i because it's used further down to remove
    the packet from the fifo.  Instead, copy the iterator and
    modify that to get the previous packet.
dev/sinic.cc:
    - don't change the transmit state and kick the machine unless
    we're at the head of the txList.
    - add a couple of debugging statements to figure out how far
    along we've gotten in processing a packet.
    - assert that the current tx vnic has something to do when
    we start processing the state machine.

47ff0af17e Virtualize sinic
separate the rx thread and tx thread and get rid of the dedicated flag.

dev/ns_gige.cc:
dev/ns_gige.hh:
dev/ns_gige_reg.h:
python/m5/objects/Ethernet.py:
    dedicated flag goes away, we have new individual flags for
    rx thread and tx thread
dev/sinic.cc:
    Virtualize sinic
    - The io registers are replicated many times in memory, allowing the NIC to
    differentiate among several virtual interfaces.
    - On the TX side, this allows multiple CPUs to initiate transmits at the same
    time without locking in the software.  If a partial packet is transmitted,
    then the state machine blocks waiting for that virtual interface to complete
    its packet.  Then the state machine will move on to the next virtual
    interface.  The commands are kept in fifo order.
    - On the RX side, multiple partial transmits can be simultaneously done.
    Though a packet does not deallocate its fifo space until all preceeding
    packets in the fifo are deallocated.  To enable multiple receives, it
    is necessary for each virtual nic to keep its own information about its
    progress through the state machine.
dev/sinic.hh:
    Virtualize sinic
    Receive state must be virtualized since we allow the receipt of packets in
    parallel.
dev/sinicreg.hh:
    Virtualize sinic
    separate rx thread and tx thread
    create a soft interrupt and add a command to trigger it.
    pad out the reserved bits in the RxDone and TxDone regs

60e92986f7 Add the capability to iterate through the packets in a pktfifo,
and to remove elements in the middle of the fifo.  These elements
do not free space, they are just marked removed.  Space is only
freed from the front of the fifo.

dev/etherpkt.cc:
    serialize the current slack
dev/etherpkt.hh:
    add "slack" to the ethernet packet.  It is to be used by any fifo that
    the packet is currently in to account for extra space that the packet
    may be occupying due to the fifo organization.

c0a4836077 Major improvements in the graph output code. Mostly adding more
options, making existing options more visible and dealing with
holes in data better.

util/stats/barchart.py:
    - move the options for BarChart to a base class ChartOptions so
    they can be more easily set and copied.
    - add an option to set the chart size (so you can adjust the aspect ratio)
    - don't do the add_subplot thing, use add_axes directly so we can
    affect the size of the figure itself to make room for the legend
    - make the initial array bottom floating point so we don't lose precision
    - add an option to set the limits on the y axis
    - use a figure legend instead of an axes legend so we can put the legend
    outside of the actual chart.  Also add an option to set the fontsize of
    the legend.
    - initial hack at outputting csv files
util/stats/db.py:
    don't print out an error when the run is missing from the database
    just return None, the error will be print elsewhere.
util/stats/output.py:
    - make StatOutput derive from ChartOptions so that it's easier to
    set default chart options.
    - make the various output functions (graph, display, etc.) take the
    name of the data as a parameter instead of making it a parameter to
    __init__.  This allows me to create the StatOutput object with
    generic parameters while still being able to specialize the name
    after the fact
    - add support for graph_group and graph_bars to be applied to multiple
    configuration groups.  This results in a cross product of the groups
    to be generated and used.
    - flush the html file output as we go so that we can load the file
    while graphs are still being generated.
    - make the proxy a parameter to the graph function so the proper system's
    data can be graphed
    - for any groups or bars that are completely missing, remove them from
    the graph.  This way, if we decide not to do a set of runs, there won't
    be holes in the data.
    - output eps and ps by default in addition to the png.
util/stats/profile.py:
    - clean up the data structures that are used to store the function
    profile information and try our best to avoid keeping extra data
    around that isn't used.
    - make get() return None if a job is missing so we know it was
    missing rather than the all zeroes thing.
    - make the function profile categorization stuff total up to 100%
    - Fixup the x-axis and y-axis labels.
    - fix the dot file output stuff.
util/stats/stats.py:
    support the new options stuff for StatOutput

0dcb288365 Cleanup the StackTrace interfaces and profile interfaces so they
are more efficient and reduce the number of new/delete calls

arch/alpha/stacktrace.cc:
    - Change the StackTrace code so that the class can more easily be
    cleaned out and reused to avoid extra allocations.
    - Allow trace() to accept a static instruction pointer so it can
    determine if the instruction is worth tracing.  This is moved from
    the CPU.
    - provide constants for special meaning PCs (user, console, unknown),
    instead of magic numbers
    - switch to using kernelSymtab instead of allSymtab which will be
    going away
    - if the stack adjustment doesn't make any sense, exit and push
    unknown so we don't get into an infinite loop or record garbage.
    - check to see if we've made too many iterations through the stack
    and panic to avoid an infinite loop
