2005-02-25Fix timing modeling of faults: functionally the very next instruction afterSteve Reinhardt
a faulting instruction is the fault handler, which appears as an independent instruction to the timing model. New code will stall fetch and not fetch the fault handler as long as there's a faulting instruction in the pipeline (i.e., the faulting inst has to commit first). Also fix Ali's bad-address assertion that doesn't apply to full system. Added some more debugging support in the process. Hopefully we'll move to the new cpu model soon and we won't need it anymore. arch/alpha/alpha_memory.cc: Reorganize lookup() so we can trace the result of the lookup as well. arch/alpha/isa_traits.hh: Add NoopMachInst (so we can insert them in the pipeline on ifetch faults). base/traceflags.py: Replace "Dispatch" flag with "Pipeline" (since I added similar DPRINTFs in other pipe stages). cpu/exetrace.cc: Change default for printing mis-speculated instructions to true (since that's often what we want, and right now you can't change it from the command line...). --HG-- extra : convert_revision : a29a98a373076d62bbbb1d6f40ba51ecae436dbc

2005-02-09Some more useful debugging info for kernel panic and die eventsRon Dreslinski
Increase the default number of CSHR's, we should really fix this or make it a parameter Use a setBlocked call to tell the bus it should block New technique for sampling and switchover: 1) Sampler switchover event happens 2) All cpus in the current phase of sampling associated with this sampler are signaled to switchover 3) Each cpu drains it's pipe of things being executed (stops fetching and waits for empty pipe) 4) Once the pipe is empty the cpu calls back to the sampler to signal it has finished, and moves into the switchedout state (continues not to fetch) 5) The sampler collects all the signals, once all cpus are drained it calls the new cpu's in the next phase to takeover from the correct cpu 6) The statistics are reset and the next switchover time is calculated from this point cpu/base_cpu.cc: cpu/base_cpu.hh: cpu/simple_cpu/simple_cpu.cc: cpu/simple_cpu/simple_cpu.hh: Reconfigure the way the sampling switchover works cpu/pc_event.cc: More debugging information on kernel panic's kern/linux/linux_system.cc: More debug info for Kernel Die events kern/linux/linux_system.hh: More debug info for kernel die events --HG-- extra : convert_revision : 61cc42e43ba738705aa1f1d167b65d4d6dee51ae

2005-02-03Add support for CPU models to execute the effectiveSteve Reinhardt
address calculation and memory access portions separately. Not currently used by any CPU models, but Kevin says he needs this. Also clean up handling of execution tracing for memory accesses (move it all into isa_desc and out of CPU models). Got rid of some ancient unused code too. arch/alpha/isa_desc: Add execute() methods to EAComp and MemAcc portions of memory access instructions, to allow CPU models to execute the effective address calculation and memory access portions separately. Requires the execution context to remember the effective address across the two invocations. Added setEA() and getEA() methods to execution context to support this. A model that does not use the split execution model can panic if these methods are called. Also added hook to call traceData->setAddr() after EA computation on any load or store operation. arch/isa_parser.py: Call traceData->setData() on memory writes (stores). cpu/simple_cpu/simple_cpu.cc: Get rid of unused code. cpu/simple_cpu/simple_cpu.hh: Add (non-functional) setEA() and getEA() methods for new split memory access execution support. --HG-- extra : convert_revision : bc2d2c758c4ca753812b9fa81f21038e55929ff0

2004-10-21Check in of various updates to the CPU. Mainly adds in stats, improvesKevin Lim
branch prediction, and makes memory dependence work properly. SConscript: Added return address stack, tournament predictor. cpu/base_cpu.cc: Added debug break and print statements. cpu/base_dyn_inst.cc: cpu/base_dyn_inst.hh: Comment out possibly unneeded variables. cpu/beta_cpu/2bit_local_pred.cc: 2bit predictor no longer speculatively updates itself. cpu/beta_cpu/alpha_dyn_inst.hh: Comment formatting. cpu/beta_cpu/alpha_full_cpu.hh: Formatting cpu/beta_cpu/alpha_full_cpu_builder.cc: Added new parameters for branch predictors, and IQ parameters. cpu/beta_cpu/alpha_full_cpu_impl.hh: Register stats. cpu/beta_cpu/alpha_params.hh: Added parameters for IQ, branch predictors, and store sets. cpu/beta_cpu/bpred_unit.cc: Removed one class. cpu/beta_cpu/bpred_unit.hh: Add in RAS, stats. Changed branch predictor unit functionality so that it holds a history of past branches so it can update, and also hold a proper history of the RAS so it can be restored on branch mispredicts. cpu/beta_cpu/bpred_unit_impl.hh: Added in stats, history of branches, RAS. Now bpred unit actually modifies the instruction's predicted next PC. cpu/beta_cpu/btb.cc: Add in sanity checks. cpu/beta_cpu/comm.hh: Add in communication where needed, remove it where it's not. cpu/beta_cpu/commit.hh: cpu/beta_cpu/rename.hh: cpu/beta_cpu/rename_impl.hh: Add in stats. cpu/beta_cpu/commit_impl.hh: Stats, update what is sent back on branch mispredict. cpu/beta_cpu/cpu_policy.hh: Change the bpred unit being used. cpu/beta_cpu/decode.hh: cpu/beta_cpu/decode_impl.hh: Stats. cpu/beta_cpu/fetch.hh: Stats, change squash so it can handle squashes from decode differently than squashes from commit. cpu/beta_cpu/fetch_impl.hh: Add in stats. Change how a cache line is fetched. Update to work with caches. Also have separate functions for different behavior if squash is coming from decode vs commit. cpu/beta_cpu/free_list.hh: Remove some old comments. cpu/beta_cpu/full_cpu.cc: cpu/beta_cpu/full_cpu.hh: Added function to remove instructions from back of instruction list until a certain sequence number. cpu/beta_cpu/iew.hh: Stats, separate squashing behavior due to branches vs memory. cpu/beta_cpu/iew_impl.hh: Stats, separate squashing behavior for branches vs memory. cpu/beta_cpu/inst_queue.cc: Debug stuff cpu/beta_cpu/inst_queue.hh: Stats, change how mem dep unit works, debug stuff cpu/beta_cpu/inst_queue_impl.hh: Stats, change how mem dep unit works, debug stuff. Also add in parameters that used to be hardcoded. cpu/beta_cpu/mem_dep_unit.hh: cpu/beta_cpu/mem_dep_unit_impl.hh: Add in stats, change how memory dependence unit works. It now holds the memory instructions that are waiting for their memory dependences to resolve. It provides which instructions are ready directly to the IQ. cpu/beta_cpu/regfile.hh: Fix up sanity checks. cpu/beta_cpu/rename_map.cc: Fix loop variable type. cpu/beta_cpu/rob_impl.hh: Remove intermediate DynInstPtr cpu/beta_cpu/store_set.cc: Add in debugging statements. cpu/beta_cpu/store_set.hh: Reorder function arguments to match the rest of the calls. --HG-- extra : convert_revision : aabf9b1fecd1d743265dfc3b174d6159937c6f44
2004-10-17Bunch of little changes for tracking copies and getting OPT right.Erik Hallnor
cpu/simple_cpu/simple_cpu.cc: Send Copy cpu/trace/opt_cpu.cc: Calculate the block size correctly. Set lookupTable value directly, since the old way only worked for FA caches. cpu/trace/trace_cpu.cc: Don't start events if the hierarchy is in non-event mode. --HG-- extra : convert_revision : daf2db5ed7428c2fb08652cf76f6fe99d8357db5
