b7b8ffa7b7 Major changes to sinic device model. Rearrage read/write, better
interrupts.

dev/sinic.cc:
    - The prepareRead function sets all the variables in the register
    file that depend on various state bits that change on the fly.
    Includes RxDone, RxWait, TxDone, and TxWait
    - Use the new register information accessor functions to grab
    validity and size information for the read and write functions
    - read all registers directly from the register space by offset
    and size, not by actual name (less code)
    - The side effect of reading the interrupt status (clearing it) now
    happens outside the actual chunk of code where the value is loaded.
    - Add an iprRead function for when we may want speculative access
    to device registers through an ipr or special instruction.
    - When RxData or TxData are written, their busy flag is set to
    indicate that they have an outstanding transaction.
    - The RxHigh and TxLow interrupts are special, they only interrupt
    if the rxEmpty or txFull limits were hit
    - Move reset to the command register
    - Update more registers on reset, clear rxEmpty and txFull
    - Data dumps only happen if EthernetData trace flag set
    - When a DMA completes, kick the other engine if it was waiting
    - implement all of the new interrupts
    - serialize the new stuff
dev/sinic.hh:
    - Put all registers with their proper size and alignment into
    the regs struct so that we can copy multiple at a time.
    - Provide accessor functions for accessing the registers with
    different sizes.
    - Flags to track when the rx fifo hit empty and the tx fifo became
    full.  These flags are used to determine what to do when below
    the watermarks, and are reset when crossing the watermark.
    - the txDmaEvent should actually trigger the txDmaDone function
    - Add an iprRead function for when we may want speculative access
    to device registers through an ipr or special instruction.
    - The prepareRead function sets all the variables in the register
    file that depend on various state bits that change on the fly.
    - add rx_max_intr and dedicated (for dedicated thread) config params
dev/sinicreg.hh:
    Add some new registers: Command, RxMaxIntr, RxFifoSize, TxFifoSize,
    rename XxThreshold to XxFifoMark
    Move Reset to the Command register
    Add Thread to the Config register
    New interrupts, better names
    More info in RxDone and TxDone
    Easier access to information on each register (size, read, write, name)
python/m5/objects/Ethernet.py:
    Both sinic and nsgige have the dedicated thread
    Add a parameter to configure the maximum number for receive
    packets per interrupt

a51565f6ae It's not necessary for a device to call recvDone, that
automatically happens in the interface after the packet
is delivered to the device.

    different name.
dev/ethertap.cc:
    fix serialization.
dev/ide_ctrl.cc:
    - the pio interface is a different simobject and should have a
    different name.
    - properly initialize variables
    - When serializing an array, the size is the number of elements,
    not the number of bytes!
dev/pcidev.cc:
    When serializing an array, the size is the number of elements,
    not the number of bytes!
dev/tsunami_io.hh:
    Don't make objects SimObjects if they're not exposed to python.
    Don't add serialization functions to events, it's generally not
    what you want.
    allow the real time clock and interval timer to serialize themselves,
    must pass a base name since it is not a SimObject and the values will
    be going into the section of the parent.

8a0bc84022 Allow CPUs to specify their own CPU ids.
Make the AlphaConsole calculate the number of CPUs instead
of passing that in as a parameter.

cpu/base.cc:
    pass the desired cpu_id into registerExecContext, offsetting it
    by the thread number.  a cpu_id of -1 means that it should be
    generated for you.
cpu/base.hh:
    Take the cpu_id as a parameter
cpu/o3/alpha_cpu_builder.cc:
cpu/simple/cpu.cc:
    Accept the cpu_id as a parameter
    while we're here, let's remove the multiplier since it is
    not used.
dev/alpha_console.cc:
    don't take the number of CPUs as a parameter.  Calculate it from
    the system based on the number of CPUs that have been registered.
    move init() code to startup() to ensure that all CPUs are registerd.
dev/alpha_console.hh:
python/m5/objects/AlphaConsole.py:
    don't take the number of CPUs as a parameter.
    move init() code to startup() to ensure that all CPUs are registerd.
python/m5/objects/BaseCPU.py:
    take the cpu_id as a parameter.  Default it to -1 which means
    that it will be generated.
sim/system.cc:
    allow the registerExecContext functioin to take a desired
    cpu_id as a parameter.  Check to ensure that the id isn't
    already used.  Accept -1 as a request to have an id assigned.
sim/system.hh:
    keep track of the number of registered exec contexts.
    provide a function for accessing the number of exec contexts
    that checks to ensure that they are all registered correctly.

036a8ceb8d Don't hard code the location of m5AlphaAccess. Instead, move the
code into a function that can be called by the AlphaConsole class.
AlphaConsole will pass in its address.

    Move Phys2K0Seg to ev5.hh and fixup the TSUNAMI uncacheable
    bits so that they will be converted correctly.
dev/alpha_access.h:

c4029ecb30 Implement a state machine clock that acutally limits how fast
the nsgige state machine can run. The frequency is of the actual
state transitions, and not the rate of what underlying
instructions might run at.

dev/ns_gige.cc:
    Implement a state machine clock that acutally limits how fast
    the state machine can run.  After each state transition, a
    variable is kept to hold the next state transition until the
    next clock.  The frequency is of the actual state transitions,
    and not the rate of what underlying instructions might run at.
dev/ns_gige.hh:
    Add back the rxKickEvent and txKickEvent events.
python/m5/objects/Ethernet.py:
    Default the state machine clock to '0ns' so the default
    behaviour doesn't change when we actually implement the
    state machine clock.
