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. arch/alpha/alpha_linux_process.cc: arch/alpha/alpha_memory.cc: arch/alpha/alpha_tru64_process.cc: arch/alpha/arguments.cc: arch/alpha/isa/decoder.isa: arch/alpha/stacktrace.cc: arch/alpha/vtophys.cc: base/remote_gdb.cc: cpu/intr_control.cc: Avoid directly accessing objects within the XC. arch/alpha/ev5.cc: Avoid directly accessing objects within the XC. KernelStats have been moved to the BaseCPU instead of the XC. arch/alpha/isa_traits.hh: Remove clearIprs(). It wasn't used very often and it did not work well with the proxy ExecContext. cpu/base.cc: Place kernel stats within the BaseCPU instead of the ExecContext. For now comment out the profiling code sampling until its exact location is decided upon. cpu/base.hh: Kernel stats are now in the BaseCPU instead of the ExecContext. cpu/base_dyn_inst.cc: cpu/base_dyn_inst.hh: cpu/memtest/memtest.cc: cpu/memtest/memtest.hh: Changes to support rename of old ExecContext to CPUExecContext.

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. arch/alpha/alpha_linux_process.cc: arch/alpha/alpha_memory.cc: arch/alpha/alpha_tru64_process.cc: arch/alpha/arguments.cc: arch/alpha/isa/decoder.isa: arch/alpha/stacktrace.cc: arch/alpha/vtophys.cc: base/remote_gdb.cc: cpu/intr_control.cc: Avoid directly accessing objects within the XC. arch/alpha/ev5.cc: Avoid directly accessing objects within the XC. KernelStats have been moved to the BaseCPU instead of the XC. arch/alpha/isa_traits.hh: Remove clearIprs(). It wasn't used very often and it did not work well with the proxy ExecContext. cpu/base.cc: Place kernel stats within the BaseCPU instead of the ExecContext. For now comment out the profiling code sampling until its exact location is decided upon. cpu/base.hh: Kernel stats are now in the BaseCPU instead of the ExecContext. cpu/base_dyn_inst.cc: cpu/base_dyn_inst.hh: cpu/memtest/memtest.cc: cpu/memtest/memtest.hh: Changes to support rename of old ExecContext to CPUExecContext.

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.

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.

ExecContext *src_xc = system->execContexts[0];
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.

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.

// Then finally set the PC and the next PC.
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.

This is likely to be removed in the future. cpu/beta_cpu/alpha_dyn_inst.cc: AlphaDynInst has been changed to be templated, so now this CC file is just used to force instantiations of AlphaDynInst. cpu/beta_cpu/alpha_dyn_inst.hh: Changed AlphaDynInst to be templated on Impl. Removed some unnecessary functions. cpu/beta_cpu/alpha_full_cpu.cc: AlphaFullCPU has been changed to be templated, so this CC file is now just used to force instantation of AlphaFullCPU. cpu/beta_cpu/alpha_full_cpu.hh: Change AlphaFullCPU to be templated on Impl. cpu/beta_cpu/alpha_impl.hh: Update it to reflect AlphaDynInst and AlphaFullCPU being templated on Impl. Also removed time buffers from here, as they are really a part of the CPU and are thus in the CPU policy now. cpu/beta_cpu/alpha_params.hh: Make AlphaSimpleParams inherit from the BaseFullCPU so that it doesn't need to specifically declare any parameters that are already in the BaseFullCPU. cpu/beta_cpu/comm.hh: Changed the structure of the time buffer communication structs. Now they include the size of the packet of instructions it is sending. Added some parameters to the backwards communication struct, mainly for squashing. cpu/beta_cpu/commit.hh: Update typenames to reflect change in location of time buffer structs. Update DynInst to DynInstPtr (it is refcounted now). cpu/beta_cpu/commit_impl.hh: Formatting changes mainly. Also sends back proper information on branch mispredicts so that the bpred unit can update itself. Updated behavior for non-speculative instructions (stores, any other non-spec instructions): once they reach the head of the ROB, the ROB signals back to the IQ that it can go ahead and issue the non-speculative instruction.

Also added in branch brediction unit. cpu/beta_cpu/fetch_impl.hh: Add in branch prediction.

Future change will be moving them to a single scoreboard to conserve space. cpu/beta_cpu/free_list.hh: Mostly debugging statements. Might be removed for performance in future. cpu/beta_cpu/full_cpu.cc: Added in some debugging statements. Updated BaseFullCPU to take a params object. cpu/beta_cpu/full_cpu.hh: Added params class within BaseCPU that other param classes will be able to inherit from.

Changed inst queue to hold non-speculative instructions as well, which are issued only when commit signals backwards that a nonspeculative instruction is at the head of the ROB. cpu/beta_cpu/inst_queue_impl.hh: Updated to allow for non-speculative instructions to be in the inst queue. Also added some debug functions. cpu/beta_cpu/regfile.hh: Added debugging statements, changed formatting. cpu/beta_cpu/rename.hh: Updated typedefs, added some functions to clean up code. cpu/beta_cpu/rename_impl.hh: Moved some code into functions to make it easier to read. cpu/beta_cpu/rename_map.cc: Changed int and float reg behavior to use a single flat namespace.

Changed how it loops through groups of instructions so it can properly block during the middle of a group of instructions. cpu/beta_cpu/fetch.hh: Changed typedefs to reflect change in location of time buffer structs and the change to ref counted DynInsts. Also added in branch brediction unit. cpu/beta_cpu/fetch_impl.hh: Add in branch prediction. Changed how fetch checks inputs and its current state to make for easier logic. cpu/beta_cpu/free_list.cc: Changed int regs and float regs to logically use one flat namespace. Future change will be moving them to a single scoreboard to conserve space. cpu/beta_cpu/free_list.hh: Mostly debugging statements. Might be removed for performance in future. cpu/beta_cpu/full_cpu.cc: Added in some debugging statements. Updated BaseFullCPU to take a params object. cpu/beta_cpu/full_cpu.hh: Added params class within BaseCPU that other param classes will be able to inherit from. Updated typedefs to reflect change in location of time buffer structs and ref counted DynInst. cpu/beta_cpu/iew.hh: Updated typedefs to reflect change in location of time buffer structs and use of ref counted DynInsts. cpu/beta_cpu/iew_impl.hh: Added in load store queue, updated iew to be able to execute non- speculative instructions, instead of having them execute in commit. cpu/beta_cpu/inst_queue.hh: Updated change to ref counted DynInsts. Changed inst queue to hold non-speculative instructions as well, which are issued only when commit signals backwards that a nonspeculative instruction is at the head of the ROB. cpu/beta_cpu/inst_queue_impl.hh: Updated to allow for non-speculative instructions to be in the inst queue. Also added some debug functions. cpu/beta_cpu/regfile.hh: Added debugging statements, changed formatting. cpu/beta_cpu/rename.hh: Updated typedefs, added some functions to clean up code. cpu/beta_cpu/rename_impl.hh: Moved some code into functions to make it easier to read. cpu/beta_cpu/rename_map.cc: Changed int and float reg behavior to use a single flat namespace. In the future, the rename maps can be combined to a single rename map to save space. cpu/beta_cpu/rename_map.hh: Added destructor. cpu/beta_cpu/rob.hh: Updated it with change from DynInst to ref counted DynInst. cpu/beta_cpu/rob_impl.hh: Formatting, updated to use ref counted DynInst. cpu/static_inst.hh: Updated forward declaration for AlphaDynInst now that it is templated. --HG-- extra : convert_revision : 1045f240ee9b6a4bd368e1806aca029ebbdc6dd3

Update to make multiple instruction issue and different latencies work. Also change to ref counted DynInst. SConscript: Add branch predictor, BTB, load store queue, and storesets. arch/isa_parser.py: Specify the template parameter for AlphaDynInst base/traceflags.py: Add load store queue, store set, and mem dependence unit to the list of trace flags. cpu/base_dyn_inst.cc: Change formating, add in debug statement. cpu/base_dyn_inst.hh: Change DynInst to be RefCounted, add flag to clear whether or not this instruction can commit. This is likely to be removed in the future. cpu/beta_cpu/alpha_dyn_inst.cc: AlphaDynInst has been changed to be templated, so now this CC file is just used to force instantiations of AlphaDynInst. cpu/beta_cpu/alpha_dyn_inst.hh: Changed AlphaDynInst to be templated on Impl. Removed some unnecessary functions. cpu/beta_cpu/alpha_full_cpu.cc: AlphaFullCPU has been changed to be templated, so this CC file is now just used to force instantation of AlphaFullCPU. cpu/beta_cpu/alpha_full_cpu.hh: Change AlphaFullCPU to be templated on Impl. cpu/beta_cpu/alpha_impl.hh: Update it to reflect AlphaDynInst and AlphaFullCPU being templated on Impl. Also removed time buffers from here, as they are really a part of the CPU and are thus in the CPU policy now. cpu/beta_cpu/alpha_params.hh: Make AlphaSimpleParams inherit from the BaseFullCPU so that it doesn't need to specifically declare any parameters that are already in the BaseFullCPU. cpu/beta_cpu/comm.hh: Changed the structure of the time buffer communication structs. Now they include the size of the packet of instructions it is sending. Added some parameters to the backwards communication struct, mainly for squashing. cpu/beta_cpu/commit.hh: Update typenames to reflect change in location of time buffer structs. Update DynInst to DynInstPtr (it is refcounted now). cpu/beta_cpu/commit_impl.hh: Formatting changes mainly. Also sends back proper information on branch mispredicts so that the bpred unit can update itself. Updated behavior for non-speculative instructions (stores, any other non-spec instructions): once they reach the head of the ROB, the ROB signals back to the IQ that it can go ahead and issue the non-speculative instruction. The instruction itself is updated so that commit won't try to commit it again until it is done executing. cpu/beta_cpu/cpu_policy.hh: Added branch prediction unit, mem dependence prediction unit, load store queue. Moved time buffer structs from AlphaSimpleImpl to here. cpu/beta_cpu/decode.hh: Changed typedefs to reflect change in location of time buffer structs and also the change from DynInst to ref counted DynInstPtr. cpu/beta_cpu/decode_impl.hh: Continues to buffer instructions even while unblocking now.
