Kevin Lim 11aead894d Updates for the quiesceEvent that was added to the XC.
Also several files need to include system.hh or symtab.hh.  This is because exec_context.hh has less #includes than before, requiring some of the files that include it to include some other files as well.

    StackTrace needs to include system.hh.
cpu/cpu_exec_context.cc:

Kevin Lim f15e492375 Steps towards setting up the infrastructure to allow the new CPU model to work in full system mode.
The major change is renaming the old ExecContext to CPUExecContext, and creating two new classes, ExecContext (an abstract class), and ProxyExecContext (a templated class that derives from ExecContext).

Code outside of the CPU continues to use ExecContext as normal (other than not being able to access variables within the XC).  The CPU uses the CPUExecContext, or however else it stores its own state.  It then creates a ProxyExecContext, templated on the class used to hold its state.  This proxy is passed to any code outside of the CPU that needs to access the XC.  This allows code outside of the CPU to use the ExecContext interface to access any state needed, without knowledge of how that state is laid out.

Note that these changes will not compile without the accompanying revision to automatically rename the shadow registers.

SConscript:
    Include new file, cpu_exec_context.cc.

Kevin Lim e7825aab59 Changes to support automatic renaming of the shadow registers at decode time. This requires using an ExtMachInst (uint64_t) instead of the normal MachInst; the ExtMachInst is packed with extra decode context information. In the case of Alpha, the PAL mode is included.
The shadow registers are folded into the normal integer registers to ease renaming indexing.

Include the removed Opcdec class of instructions for faulting when a pal mode only instruction is decoded in non-pal mode.

arch/alpha/isa/main.isa:
    Changes for automatically using the shadow registers.  Now instructions must decode based on an ExtMachInst, which is a MachInst with any decode context information concatenated onto the higher order bits.

    The decoder (for Alpha) uses the 32nd bit in order to determine if the machine is in PAL mode.  If it is, then it refers to the reg_redir table to determine the true index of the register it is using.

    Also include the opcdec instruction definition.
arch/alpha/isa_traits.hh:
    Define ExtMachInst type that is used by the static inst in order to decode the instruction, given the context of being in pal mode or not.

    Redefine the number of Int registers, splitting it into NumIntArchRegs (32) and NumIntRegs (32 + 8 shadow registers).

    Change the dependence tags to reflect the integer registers include the 8 shadow registers.

    Define function to make an ExtMachInst.  Currently it is somewhat specific to Alpha; in the future it must be decided to make this more generic and possibly slower, or leave it specific to each architecture and ifdef it within the CPU.
arch/isa_parser.py:
    Have static insts decode on the ExtMachInst.
base/remote_gdb.cc:
    Support the automatic remapping of shadow registers.  Remote GDB must now look at the PC being read in order to tell if it should use the normal register indices or the shadow register indices.
cpu/o3/regfile.hh:
    Comment out the pal registers; they are now a part of the integer registers.
cpu/simple/cpu.cc:

Kevin Lim 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.

Kevin Lim 485568efa9 Fixes to handle generating the initiateAcc and completeAcc functions a little more cleanly.
arch/alpha/isa/mem.isa:
    Avoid explicitly declaring the Mem variable.  Instead break up the code blocks used to generate the initiate and complete functions.  The templates reflect which operands need to be declared for each function (src, dest, or both).

    Loads use both the EA code and mem acc code for the initiate, and memacc code and postacc code for the complete.
    Stores use both the EA code and mem acc code for the initiate, and only post acc code for the complete.

Gabe Black 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.

Kevin Lim 2d04f18674 Gives separate methods for initiating and completing a memory access, which will be helpful for the merged memory model.
arch/alpha/isa/mem.isa:
    Include methods that allow a memory operation to be split between the part that initiates the access, and the part that completes the access.  In these functions the Mem variable is explicitly declared; in the default execute functions, the Mem variable is still handled through %(op_decl)s.
arch/isa_parser.py:
    Include recording the type of the memory access variable so that it can be used if it needs to be explicitly declared in a template.

    Have memory operands consider themselves neither a source nor a destination to avoid including themselves on the op_src_decl list or the op_dest_decl list.

    Record op_src_decl and op_dest_decl lists to allow for declaring only source or destination operands.  This is needed for the split memory access methods.

    are the same).
arch/isa_parser.py:
    Add two new features to instruction format functions:
    - Keyword parameters, a la Python.
    - List-valued arguments.

    Also export makeList() function to Python code blocks,
    as this is handy for dealing with flags.

Steve Reinhardt 3923eec0ef Change how memory operands are handled in ISA descriptions.
Should enable implementation of split-phase timing loads
with new memory model.
May create slight timing differences under FullCPU, as I
believe we were not handling software prefetches correctly
before when the split MemAcc/Exec model was used.  I haven't
looked into this in any detail though.

arch/alpha/isa/decoder.isa:
    HwLoadStore format split into separate HwLoad and
    HwStore formats.
    Copy instructions now fall under MiscPrefetch format.
    Mem_write_result is now just write_result in store
    conditionals.
arch/alpha/isa/mem.isa:
    Split MemAccExecute and LoadStoreExecute templates
    into separate templates for loads and stores; now
    that memory operands are handled differently from
    registers, it's impossible to have a single template
    serve both.
    Also unified the handling of "regular" prefetches
    (loads to r31) and "misc" prefetches (e.g., wh64)
    under the new scheme.  It looks like SW prefetches
    were not handled correctly in FullCPU up til now,
    since we generated an execute() method for the outer
    instruction but didn't generate a proper method for
    MemAcc::execute() (instead getting a default no-op
    method for that).
arch/alpha/isa/pal.isa:
    Split HwLoadStore into separate HwLoad and HwStore
    formats to select proper template (see change to
    mem.isa in this changeset).
arch/isa_parser.py:
    Stop trying to treat memory operands like register
    operands, since we never used them in a uniform way
    anyway, and it made it impossible to do split-phase
    loads as needed for the new CPU model.  Now there's no
    more 'op_mem_rd', 'op_nonmem_rd', etc.: 'op_rd' just does
    register operands, and the template code is responsible
    for formulating the call to the memory system.  Right now
    the only thing exported by InstObjParams is a new attribute
    'mem_acc_size' which gives the memory access size in bits,
    though more attributes can be added if needed.

    Also moved code in findOperands() method to
    OperandDescriptorList.__init__(), which is where it belongs.

Gabe Black 82f2ae56ed Alot of changes to push towards ISA independence. Highlights are renaming of the isa_desc files, movement of byte_swap.hh into sim, and the creation of arch/isa_traits.hh
SConscript:

Steve Reinhardt 03a2aca9a9 Changes for Process object initialization in merged-memory environment.
System object now exists for both fullsys and syscall emulation, as the
latter needs it so that Process objects can find the shared PhysicalMemory

python/m5/objects/System.py:
    Segregate full-system only Process parameters (most of them!).
sim/process.cc:
    Take System argument in constructor.
    Move initialization to startup() callback to occur after system & cpus
    are initialized.
    Generate ProxyMemory object to pass to loader for transparent
    virtual page allocation.
sim/process.hh:
    Take System argument in constructor.
    Move initialization to startup() callback to occur after system & cpus
    are initialized.
sim/system.cc:
sim/system.hh:
    Enable System object for non-full-system too.
    Basically involved putting most of the existing code
    inside '#ifdef FULL_SYSTEM'.
    Key thing needed for syscall emulation at this point is
    the PhysicalMemory object (for Process initialization).
