| 2005-05-03 | Large update of several parts of my code. The most notable change is the ↵ | Kevin Lim | |
| inclusion of a full-fledged load/store queue. At the moment it still has some issues running, but most of the code is hopefully close to the final version. SConscript: arch/isa_parser.py: cpu/base_dyn_inst.cc: Remove OOO CPU stuff. arch/alpha/faults.hh: Add fake memory fault. This will be removed eventually. arch/alpha/isa_desc: Change EA comp and Mem accessor to be const StaticInstPtrs. cpu/base_dyn_inst.hh: Update read/write calls to use load queue and store queue indices. cpu/beta_cpu/alpha_dyn_inst.hh: Change to const StaticInst in the register accessors. cpu/beta_cpu/alpha_dyn_inst_impl.hh: Update syscall code with thread numbers. cpu/beta_cpu/alpha_full_cpu.hh: Alter some of the full system code so it will compile without errors. cpu/beta_cpu/alpha_full_cpu_builder.cc: Created a DerivAlphaFullCPU class so I can instantiate different CPUs that have different template parameters. cpu/beta_cpu/alpha_full_cpu_impl.hh: Update some of the full system code so it compiles. cpu/beta_cpu/alpha_params.hh: cpu/beta_cpu/fetch_impl.hh: Remove asid. cpu/beta_cpu/comm.hh: Remove global history field. cpu/beta_cpu/commit.hh: Comment out rename map. cpu/beta_cpu/commit_impl.hh: Update some of the full system code so it compiles. Also change it so that it handles memory instructions properly. cpu/beta_cpu/cpu_policy.hh: Removed IQ from the IEW template parameter to make it more uniform. cpu/beta_cpu/decode.hh: Add debug function. cpu/beta_cpu/decode_impl.hh: Slight updates for decode in the case where it causes a squash. cpu/beta_cpu/fetch.hh: cpu/beta_cpu/rob.hh: Comment out unneccessary code. cpu/beta_cpu/full_cpu.cc: Changed some of the full system code so it compiles. Updated exec contexts and so forth to hopefully make multithreading easier. cpu/beta_cpu/full_cpu.hh: Updated some of the full system code to make it compile. cpu/beta_cpu/iew.cc: Removed IQ from template parameter to IEW. cpu/beta_cpu/iew.hh: Removed IQ from template parameter to IEW. Updated IEW to recognize the Load/Store queue. cpu/beta_cpu/iew_impl.hh: New handling of memory instructions through the Load/Store queue. cpu/beta_cpu/inst_queue.hh: Updated comment. cpu/beta_cpu/inst_queue_impl.hh: Slightly different handling of memory instructions due to Load/Store queue. cpu/beta_cpu/regfile.hh: Updated full system code so it compiles. cpu/beta_cpu/rob_impl.hh: Moved some code around; no major functional changes. cpu/ooo_cpu/ooo_cpu.hh: Slight updates to OOO CPU; still does not work. cpu/static_inst.hh: Remove OOO CPU stuff. Change ea comp and mem acc to return const StaticInst. kern/kernel_stats.hh: Extra forward declares added due to compile error. --HG-- extra : convert_revision : 594a7cdbe57f6c2bda7d08856fcd864604a6238e | |||
| 2005-02-11 | Fix up #defines to use full path; fix up code for g++ 3.4 | Kevin Lim | |

| 2004-09-23 | Update to make multiple instruction issue and different latencies work. | Kevin Lim | |
| 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. 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 | |||

| caches. SConscript: Added new CPU files to build. arch/alpha/isa_desc: Changed rduniq and wruniq to be nonspeculative because the uniq register is not renamed. arch/isa_parser.py: Added new CPU exec method. base/statistics.hh: Minor change for namespace conflict. Probably can change back one the new CPU files are cleaned up. base/traceflags.py: Added new CPU trace flags. cpu/static_inst.hh: Changed static inst to use a file that defines the execute functions. --HG-- extra : convert_revision : bd4ce34361308280168324817fc1258dd253e519 | |||
