2005-05-03Large update of several parts of my code. The most notable change is the ↵Kevin Lim

2005-04-11Make the notion of a global event tick independent of the actualNathan Binkert
CPU cycle ticks. This allows the user to have CPUs of different frequencies, and also allows frequencies and latencies that are not evenly divisible by the CPU frequency. For now, the CPU frequency is still set to the global frequency, but soon, we'll hopefully make the global frequency fixed at something like 1THz and set all other frequencies independently. arch/alpha/ev5.cc: The cycles counter is based on the current cpu cycle. cpu/base_cpu.cc: frequency isn't the cpu parameter anymore, cycleTime is. cpu/base_cpu.hh: frequency isn't the cpu parameter anymore, cycleTime is. create several public functions for getting the cpu frequency and the numbers of ticks for a given number of cycles, etc. cpu/memtest/memtest.cc: cpu/simple_cpu/simple_cpu.cc: cpu/simple_cpu/simple_cpu.hh: cpu/trace/trace_cpu.cc: Now that ticks aren't cpu cycles, fixup code to advance by the proper number of ticks. cpu/memtest/memtest.hh: cpu/trace/trace_cpu.hh: Provide a function to get the number of ticks for a given number of cycles. dev/alpha_console.cc: Update for changes in the way that frequencies and latencies are accessed. Move some stuff to init() dev/alpha_console.hh: Need a pointer to the system and the cpu to get the frequency so we can pass the info to the console code. dev/etherbus.cc: dev/etherbus.hh: dev/etherlink.cc: dev/etherlink.hh: dev/ethertap.cc: dev/ide_disk.hh: dev/ns_gige.cc: dev/ns_gige.hh: update for changes in the way bandwidths are passed from python to C++ to accomidate the new way that ticks works. dev/ide_disk.cc: update for changes in the way bandwidths are passed from python to C++ to accomidate the new way that ticks works. Add some extra debugging printfs dev/platform.cc: dev/sinic.cc: dev/sinic.hh: outline the constructor and destructor dev/platform.hh: outline the constructor and destructor. don't keep track of the interrupt frequency. Only provide the accessor function. dev/tsunami.cc: dev/tsunami.hh: outline the constructor and destructor Don't set the interrupt frequency here. Get it from the actual device that does the interrupting. dev/tsunami_io.cc: dev/tsunami_io.hh: Make the interrupt interval a configuration parameter. (And convert the interval to the new latency/frequency stuff in the python) kern/linux/linux_system.cc: update for changes in the way bandwidths are passed from python to C++ to accomidate the new way that ticks works. For now, we must get the boot cpu's frequency as a parameter since allowing the system to have a pointer to the boot cpu would cause a cycle. kern/tru64/tru64_system.cc: For now, we must get the boot cpu's frequency as a parameter since allowing the system to have a pointer to the boot cpu would cause a cycle. python/m5/config.py: Fix support for cycle_time relative latencies and frequencies. Add support for getting a NetworkBandwidth or a MemoryBandwidth. python/m5/objects/BaseCPU.mpy: All CPUs now have a cycle_time. The default is the global frequency, but it is now possible to set the global frequency to some large value (like 1THz) and set each CPU frequency independently. python/m5/objects/BaseCache.mpy: python/m5/objects/Ide.mpy: Make this a Latency parameter python/m5/objects/BaseSystem.mpy: We need to pass the boot CPU's frequency to the system python/m5/objects/Ethernet.mpy: Update parameter types to use latency and bandwidth types python/m5/objects/Platform.mpy: this frequency isn't needed. We get it from the clock interrupt. python/m5/objects/Tsunami.mpy: The clock generator should hold the frequency sim/eventq.hh: Need to remove this assertion because the writeback event queue is different from the CPU's event queue which can cause this assertion to fail. sim/process.cc: Fix comment. sim/system.hh: Struct member to hold the boot CPU's frequency. sim/universe.cc: remove unneeded variable. --HG-- extra : convert_revision : 51efe4041095234bf458d9b3b0d417f4cae16fdc

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

output files and the output directory are are handled. Make the output directory configuration via a command line parameter, or an environment variable. SConscript: Add new output file stuff base/misc.cc: dev/simconsole.cc: use new output file code cpu/base_cpu.cc: use new output file code to generate output streams dev/etherdump.cc: use the output file code to find the output directory use a real stream instead of a pointer dev/etherdump.hh: use a real stream instead of a pointer objects/Root.mpy: output_dir and config_output_file are not longer configured here. sim/main.cc: - Completely rework the command line argument passing to deal with changes in python and output files. - Update help output to reflect changes. - Remove all direct support for .ini files. They are strictly for intermediate representation. - Remove the --foo:bar=blah syntax for .ini files and add --foo.bar=blah syntax for python. This will generate: foo.bar = 'blah' in the python script. - Add '-d' to set the output directory. - Use new output file code to access the output stream. sim/serialize.cc: use the new code to find the output directory sim/universe.cc: Get rid of makeOutputStream. Use the new output file code. Remove output_dir and config_output_file as parameters. --HG-- extra : convert_revision : df2f0e13d401c3a60cae1239aa1ec3511721544d

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

2005-01-14Fixes so m5 compiles on gcc 3.4, which has much stricter syntax. Most ↵Kevin Lim
changes come from templated code, which is evaluated slightly differently than in previous versions of gcc. arch/alpha/alpha_linux_process.cc: Alphabetize includes. arch/alpha/vptr.hh: Change the constants that are being used for alpha pagebytes to come from the ISA. base/random.hh: cpu/static_inst.cc: sim/param.cc: Fix up template syntax. base/range.hh: Include iostream for << operator. base/res_list.hh: base/statistics.hh: cpu/simple_cpu/simple_cpu.hh: cpu/static_inst.hh: sim/eventq.hh: sim/param.hh: Fixup for templated code to resolve different scope lookup in gcc 3.4. This defers the lookup of the function/variable until actual instantiation time by making it dependent on the templated class/function. base/trace.cc: Fix call to new. base/trace.hh: Fix up #define to have full path. cpu/base_cpu.cc: Fix up call to new. dev/etherlink.hh: dev/ns_gige.hh: dev/sinic.hh: Fixup for friend class/function declaration. g++ 3.4 no longer allows typedefs to be declared as a friend class. dev/pcidev.hh: Fix up re-definition of access level to params. kern/linux/linux_syscalls.hh: kern/tru64/tru64_syscalls.hh: Fix up header. Fix up template syntax. sim/serialize.cc: Include errno.h. sim/startup.cc: Change startupq. queue was getting destructed before all things had called ~StartupCallback(), which lead to a segfault. This puts startupq in global space, and we allocate it ourselves. Other code may be similar to this and may need changing in the future. sim/syscall_emul.hh: Include cpu/exec_context.hh and sim/process.hh, as forward declarations are no longer sufficient. sim/universe.cc: Include errno.h --HG-- extra : convert_revision : e49d08ee89eb06a28351f02bafc028ca6652d5af
