70b35bab57 Changes to put all the misc regs within the misc reg file. This includes the FPCR, Uniq, lock flag, lock addr, and IPRs.
They are now accessed by calling readMiscReg()/setMiscReg() on the XC.  Old IPR accesses are supported by using readMiscRegWithEffect() and setMiscRegWithEffect() (names may change in the future).

arch/alpha/alpha_memory.cc:
    Change accesses to IPR to go through the XC.
arch/alpha/ev5.cc:
    Change accesses for IPRs to go through the misc regs.
arch/alpha/isa/decoder.isa:
    Change accesses to IPRs to go through the misc regs.  readIpr() and setIpr() are now changed to calls to readMiscRegWithEffect() and setMiscRegWithEffect().
arch/alpha/isa/fp.isa:
    Change accesses to IPRs and Fpcr to go through the misc regs.
arch/alpha/isa/main.isa:
    Add support for all misc regs being accessed through readMiscReg() and setMiscReg().  Instead of readUniq and readFpcr, they are replaced by calls with Uniq_DepTag and Fpcr_DepTag passed in as the register index.
arch/alpha/isa_traits.hh:
    Change the MiscRegFile to a class that handles all accesses to MiscRegs, which in Alpha include the FPCR, Uniq, Lock Addr, Lock Flag, and IPRs.
    Two flavors of accesses are supported: normal register reads/writes, and reads/writes with effect.  The latter are basically the original read/write IPR functions, while the former are normal reads/writes.

    The lock flag and lock addr registers are added to the dependence tags in order to support being accessed through the misc regs.
arch/alpha/stacktrace.cc:
cpu/simple/cpu.cc:
dev/sinic.cc:
    Change accesses to the IPRs to go through the XC.
arch/alpha/vtophys.cc:
    Change access to the IPR to go through the XC.
arch/isa_parser.py:
    Change generation of code for control registers to use the readMiscReg and setMiscReg functions.
base/remote_gdb.cc:
    Change accesses to the IPR to go through the XC.
cpu/exec_context.hh:
    Use the miscRegs to access the lock addr, lock flag, and other misc registers.
cpu/o3/alpha_cpu.hh:
cpu/simple/cpu.hh:
    Support interface for reading and writing misc registers, which replaces readUniq, readFpcr, readIpr, and their set functions.
cpu/o3/alpha_cpu_impl.hh:
    Change accesses to the IPRs to go through the miscRegs.
    For now comment out some of the accesses to the misc regs until the proxy exec context is completed.
cpu/o3/alpha_dyn_inst.hh:
    Change accesses to misc regs to use readMiscReg and setMiscReg.
cpu/o3/alpha_dyn_inst_impl.hh:
    Remove old misc reg accessors.
cpu/o3/cpu.cc:
    Comment out old misc reg accesses until the proxy exec context is completed.
cpu/o3/cpu.hh:
    Change accesses to the misc regs.
cpu/o3/regfile.hh:
    Remove old access methods for the misc regs, replace them with readMiscReg and setMiscReg.  They are dummy functions for now until the proxy exec context is completed.
kern/kernel_stats.cc:
kern/system_events.cc:
    Have accesses to the IPRs go through the XC.
kern/tru64/tru64.hh:
    Have accesses to the misc regs use the new access methods.

    Commented out where _faults is initialized. This statistic will probably be moved elsewhere in the future.
kern/kernel_stats.hh:

1166d4f0bf Get rid of the xc from the alphaAccess/alphaConsole backdoor device.
Now allocate an array of stacks indexed by cpu number which specify
cpu stacks and are initialized by cpu 0. Othe cpus spin waiting for
their stacks before continuing. This change *REQUIRES* a the new

10c79efe55 Changed the fault enum into a class, and fixed everything up to work with it. Next, the faults need to be pulled out of all the other code so that they are only used to communicate between the CPU and the ISA.
SConscript:
    The new faults.cc file in sim allocates the system wide faults. When these faults are generated through a function interface in the ISA, this file may go away.
arch/alpha/alpha_memory.cc:
    Changed Fault to Fault * and took the underscores out of fault names.
arch/alpha/alpha_memory.hh:
    Changed Fault to Fault *. Also, added an include for the alpha faults.
arch/alpha/ev5.cc:
    Changed the fault_addr array into a fault_addr function. Once all of the faults can be expected to have the same type, fault_addr can go away completely and the info it provided will come from the fault itself. Also, Fault was changed to Fault *, and underscores were taken out of fault names.
arch/alpha/isa/decoder.isa:

    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.

python/m5/objects/Ethernet.py:
    dedicated flag goes away, we have new individual flags for

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.

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
