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

2005-02-09Some 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

2004-08-20- Clean up and factor out all of the binning code into aNathan Binkert
single place so it's easier to work with. - Add support for binning kernel/user/idle time separately from lisa's binning stuff, but make the two compatible. - KernelStats used to directly implement the pImpl idiom, but it makes more sense to just remove the level of indirection and make the exec context have a pointer to the stats. - Factor common code out of LinuxSystem and Tru64System and put it into the System base class. While doing that, make all constructors take a pointer to a parameter struct instead of naming the parameters individually to make it much easier to add parameters to these classes. SConscript: Move the function tracking and binning stuff around. arch/alpha/ev5.cc: kernelStats is now a pointer arch/alpha/pseudo_inst.cc: kernelStats is now a pointer the parameters to the system have been moved into their own struct base/trace.hh: provide a little functor class for wrapping a string that can allow you to define name() in any scope very simply for use with DPRINTF cpu/base_cpu.cc: New order of arguments for consistency. cpu/exec_context.cc: kernelStats no longer has the level of indirection in it, execContext has the indirection now. so, kernelStats is a pointer. We also need a pointer to the kernelBinning stuff from the system and we need to figure out if we want to do binning or not. Move a whole bunch of code into kern_binning.cc so it's all in the same place. cpu/exec_context.hh: We want pointers to the kernel binning/stats stuff and we'll have the exec_context and system have the level of indirection instead of having the extra layer in the kernel stats class. cpu/simple_cpu/simple_cpu.cc: call through the exec context to do the special binning stuff. kern/kernel_stats.cc: kern/kernel_stats.hh: Re-organize the stats stuff and remove the level of indirection (that was there to simplify building) and move the binning stuff into its own class/file. kern/linux/linux_system.cc: kern/linux/linux_system.hh: kern/tru64/tru64_system.cc: kern/tru64/tru64_system.hh: sim/system.cc: sim/system.hh: move lots of common system code into the base system class so that it can be shared between linux, tru64, and whatever else we decide to support in the future.

2004-06-15Get software prefetching to work in full-system mode.Steve Reinhardt
Mostly a matter of keeping prefetches to invalid addrs from messing up VM IPRs. Also discovered that wh64s were not being treated as prefetches, when they really should be (for the most part, anyway). arch/alpha/alpha_memory.cc: arch/alpha/alpha_memory.hh: - Get rid of intrlock flag for locking VM fault regs (a la EV5); instead, just don't update regs on VPTE loads (a la EV6). - Add NO_FAULT MemReq flag to indicate references that should not cause page faults (i.e., prefetches). arch/alpha/ev5.cc: - Get rid of intrlock flag for locking VM fault regs (a la EV5); instead, just don't update regs on VPTE loads (a la EV6). - Add Fault trace flag. arch/alpha/isa_desc: - Add NO_FAULT MemReq flag to indicate references that should not cause page faults (i.e., prefetches). - Mark wh64 as a "data prefetch" instruction so it gets controlled properly by the FullCPU data prefetch control switch. - Align wh64 EA in decoder so issue stage doesn't need to worry about it. arch/alpha/isa_traits.hh: - Get rid of intrlock flag for locking VM fault regs (a la EV5); instead, just don't update regs on VPTE loads (a la EV6). base/traceflags.py: - Add Fault trace flag. cpu/simple_cpu/simple_cpu.hh: - Pass MemReq flags to writeHint() operation. cpu/static_inst.hh: Update comment re: prefetches. --HG-- extra : convert_revision : 62e466b0f4c0ff9961796270fa2e371ec24bcbb6

arch/alpha/ev5.cc: Added templatized processInterrupts() function that can be used by all of the CPU models. arch/alpha/isa_desc: Merged in changes to remove CPU dependence. arch/isa_parser.py: Merged in changes. cpu/static_inst.hh: Includes FastCPU execute methods. --HG-- extra : convert_revision : fcaa1dca35a9b316c73982bec8680df564f50bd8
2004-05-27FastCPU model added. It's very similar to the SimpleCPU, just without a lot ↵Kevin Lim
of the stats tracking. Also various changes to make the CPU model less ISA dependent, which includes moving the code that checks for interrupts up to the ISA level, moving code that zeroes the zero registers up to the ISA level, and removing opcode and ra from the regfile. arch/alpha/alpha_memory.cc: The regfile has been changed so it no longer has the opcode and ra. Instead the xc holds the actual instruction, and from there the opcode and ra can be obtained with OPCODE() and RA(). arch/alpha/ev5.cc: Moved code that once existed within simpleCPU to ev5, and templatized it. This way the CPU models can call processInterrupts and the ISA specific interrupt handling is left to the ISA's code. Also moved ISA specific zero registers from simpleCPU to here. arch/alpha/ev5.hh: Added macros for obtaining the opcode and ra from the instruction itself, as there is no longer opcode or ra in the regfile. arch/alpha/isa_desc: Added in declarations for the FastCPU model. arch/alpha/isa_traits.hh: Removed opcode and ra from the regfile. The xc now holds the actual instruction, and the opcode and ra can be obtained through it. Also added the declaration for the templated zeroRegisters() function, which will set the zero registers to 0. arch/isa_parser.py: Added in FastCPUExecContext so it will generate code for the FastCPU model as well. cpu/exec_context.cc: Added in a more generic trap function so "ev5_trap" doesn't need to be called. It currently still calls the old method, with plans for making this ISA dependent in the future. cpu/exec_context.hh: Exec context now has the instruction within it. Also added methods for exec context to read an instruction from memory, return the current instruction, and set the instruction if needed. Also has declaration for more generic trap() function. cpu/simple_cpu/simple_cpu.cc: Removed references to opcode and ra, and instead sets the xc's instruction with the fetched instruction. cpu/static_inst.hh: Added declaration for execute() using FastCPUExecContext. --HG-- extra : convert_revision : 0441ea3700ac50b733e485395d4dd4ac83666f92

2004-05-18Add a level of indirection to the register accessors used inSteve Reinhardt
instruction execute methods. Register i now means the instruction's i'th src (or dest) operand, not architectural register i. Current models that use the architectural reg index can look that up easily in the instruction object. Future models that do register renaming should find this much simpler to deal with. arch/isa_parser.py: Generate register accessors with an extra level of indirection. cpu/simple_cpu/simple_cpu.hh: Modify register accessors to use an extra level of indirection. --HG-- extra : convert_revision : f4c7d6bfa92fb2ea6251f31ee368809c3643f08f
2004-05-17Significant changes to ISA description to completely factorSteve Reinhardt
out CPU model. ISA description now generates multiple output source files to (in theory) reduce compilation time. arch/alpha/isa_desc: Update for parser changes. Move most constructors out of class declarations (which are now in decoder.hh) and into decoder.cc. Move all execute() methods into exec output. arch/isa_parser.py: Significant changes to make ISA description completely independent of CPU model, and isolate model-dependent parts of parser into one little class (CpuModel). Also split up code output into multiple files (a header, a main source file, and per-cpu execute() method files). Noticeable changes to language as a result. See updated Doxygen documentation. cpu/simple_cpu/simple_cpu.hh: SimpleCPUExecContext typedef no longer needed. Add forward declaration of Process. cpu/static_inst.hh: SimpleCPUExecContext and FullCPUExecContext typedefs no longer needed. Make eaCompInst() and memAccInst() return const refs. --HG-- extra : convert_revision : 71471f267804fafd0a881bac7445677e76334daf
