8e9d44477c Major update to sinic to support VSINIC better
dev/sinic.cc:
    - Size the virtualRegs array based on the configured value
    - Add debugging stuff for uniquely identifying vnic usage
    - Only count totally unprocessed packets when notifying via RxDone
    - Add initial virtual address support
    - Fix some bugs in accessing packets out of order to make sure that
    busy packets are processed first
    - Add fifo watermark stuff
    - Make number of vnics, zero/delay copy and watermarks parameters
dev/sinic.hh:
    add rxUnique and txUnique to uniquely identify tx and rx VNICs
    Create a separate list of Busy VNICs since more than one might
    be busy and we want to service those first
    Add more watermark stuff and new parameters
dev/sinicreg.hh:
    Make the number of virtual nics a read-only parameter
    add bits for ZeroCopy/DelayCopy
    rename Virtual to Vaddr so it's not ambiguous
    Add a flag for TxData/RxData to indicate a virtual address
    Report rxfifo status in RxDone
python/m5/objects/Ethernet.py:
    add more options for the fifo thresholds
    add number of vnics as a parameter
    add copy type as a parameter
    add virtual addressing as a parameter

3d99b4a544 Fixes to SPARC syscall emulation mode.
arch/sparc/isa/base.isa:
    Added a set of abbreviations for the different condition tests.
arch/sparc/isa/decoder.isa:
    Fixes and additions to get syscall emulation closer to working.
arch/sparc/isa/formats/branch.isa:
    Fixed branches so that the immediate version actually uses the immediate value
arch/sparc/isa/formats/integerop.isa:
    Compute the condition codes -before- writing to the state of the machine.
arch/sparc/isa/formats/mem.isa:
    An attempt to fix up the output of the disassembly of loads and stores.
arch/sparc/isa/formats/trap.isa:
    Added code to disassemble a trap instruction. This probably needs to be fixed up so there are immediate and register versions.
arch/sparc/isa/operands.isa:
    Added an R1 operand, and fixed up the numbering
arch/sparc/isa_traits.hh:
    SyscallNumReg is no longer needed, the max number of sources and destinations are fixed up, and the syscall return uses xcc instead of icc.

    Fixed up how the initial stack frame is set up.
arch/sparc/regfile.hh:
    Changed the number of windows from 6 to 32 so we don't have to worry about spill and fill traps for now, and commented out the register file setting itself up.

48f2626eac These fixes now allow all of the 20 mips tests to work properly!
Floating Point Mips Tests still need to be added, tested, and debugged.

arch/mips/isa/decoder.isa:
    Fix mult and multu instructions. This semantic error causes the problem: <int64> = <int32> * <int32>. Although I was placing
    the output into a 64-bit integer the multiply was just doing a 32-bit multiply so the solution is to just use
    the 'sd' & 'ud' operands so that the ISA parser will use the int64_t and uint64_t types in calculation.
arch/mips/isa/formats/int.isa:
    Trace output fix. Don't print first comma unless there is a destination register for sure!

5afed24e1c Changes that get rid of the OSFlags and derive a new class of this format <architecture>-<OS>.
This class is derived from the original <OS> class and is used to define information that
is both architecure and OS specific (for example, the AlphaLinux class is derived from the
Linux class and defined in arch/alpha/linux/linux.hh).

SConscript:

4f430e9ab5 Finally MIPS does hello world!
arch/mips/isa/bitfields.isa:
    add RS_SRL bitfield ...these must be set to 0 for a SRL instruction
arch/mips/isa/decoder.isa:
    Make unimplemented instructions Fail instead of just Warn
    Edits to SRA & SRAV instructions
    Implement CFC1 instructions
    Unaligned Memory Access Support (Maybe Not fully functional yet)
    Enforce a more strict decode policy (in terms of different bitfields set to 0 on certain instructions)
arch/mips/isa/formats/branch.isa:
    Fix disassembly
arch/mips/isa/formats/int.isa:
    Add sign extend Immediate and zero extend Immediate to Int class.
    Probably a bit unnecessary in the long run since these manipulations could
    be done in the actually instruction instead of keep a int value
arch/mips/isa/formats/mem.isa:
    Comment/Remove out split-memory access code... revisit this after SimpleCPU works
arch/mips/isa/formats/unimp.isa:
    Add inst2string function to Unimplemented panic. PRints out the instruction
    binary to help in debuggin
arch/mips/isa/formats/unknown.isa:
    define inst2string function , use in unknown disassembly and panic function
arch/mips/isa/operands.isa:
    Make "Mem" default to a unsigned word since this is MIPS32
arch/mips/isa_traits.hh:
    change return values to 32 instead of 64
arch/mips/linux_process.cc:
    assign some syscalls to the right functions
cpu/static_inst.hh:
    more debug functions for MIPS (these will be move to the mips directory soon)
mem/page_table.cc:
mem/page_table.hh:
    toward a better implementation for unaligned memory access
mem/request.hh:
    NO ALIGN FAULT flag added to support unaligned memory access
sim/syscall_emul.cc:
    additional SyscallVerbose comments

9e3d79694c Move to a model with a unified request object.
Constructor takes a bool to signify that it is either a cpu_request or not a cpu_request.
When accedding variables of a cpu_request it asserts that it is a cpu_request.
It also asserts that a value being read has been written at some point in time prior (not gaurnteeing it is up to date, but it was at least written before read).

There is also a isCpuReq() function to determine if this is a cpu_request.  It should be called before accesing a cpu_request only variable.

SConscript:
    Add compilation support for request.cc

mem/port.cc:
    Update for unified request object and accessor functions.
mem/request.hh:
    Remove CpuRequest, make it a unified object.  Make variables private with accessor functions.

    May want to move things from .cc file into header (usually a assert() and either returning a value, or writting two).
