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
2005-01-15New and improved configuration mechanism. No more writing ofNathan Binkert
wierd ini files. The ini files are still used as an intermediate step, but a sophisticated python library exists to help build them more easily. SConscript: add the new embedded file stuff remove all of the old object description junk base/inifile.cc: base/inifile.hh: get rid of findDefault and findAppend since they were the source of much evil. base/trace.cc: For now, if we don't have the dprintf_stream set up, dump to standard out. We probably want a command line option for this. dev/alpha_console.cc: PioDevice now takes a platform parameter. All PioDevices must have a pio_latency parameter. We stick a dummy parameter in here for now until we get rid of the builder stuff. dev/alpha_console.hh: don't need Platform anymore dev/baddev.cc: PioDevice now takes a platform parameter. All PioDevices must have a pio_latency parameter. We stick a dummy parameter in here for now until we get rid of the builder stuff. Same for the platform parameter, though we just pass the PioDevice a null parameter since it isn't used by this device and it's quicker. dev/baddev.hh: fix #include guards dev/etherlink.cc: rename parameters. dev/ethertap.cc: rename parameters dev/ide_ctrl.cc: All devices need an address even if it will get overwritten later. dev/ide_disk.cc: use an enum for the drive ID stuff. rename disk_delay -> delay Actually, I think that we should implement "cable select" and have the controller tell the drive what it is. dev/io_device.cc: dev/io_device.hh: All IO devices take a Platform * dev/ns_gige.cc: all devices need an io_bus. rename header_bus to io_bus We don't need stuff for the interrupt controller since it's all in the platform now. dev/ns_gige.hh: We don't need stuff for the interrupt controller now since it's all in the platform. dev/pciconfigall.cc: Pass a dummy NULL to the PioDevice for the platform since we don't need one. dev/pcidev.cc: Move a bunch of common functionality into the PciDev dev/platform.hh: remove unneeded code dev/tsunami.cc: remove unused param dev/tsunami_cchip.cc: pass platform pointer dev/tsunami_io.cc: dev/tsunami_pchip.cc: dev/uart.cc: pass platform variable dev/uart.hh: don't need to keep a platform pointer. it's in the base class kern/linux/linux_system.cc: kern/tru64/tru64_system.cc: rename some parameters sim/builder.cc: clean up builder code. use more parameters from the config node. all sections with a type= are now created, the old mechanisms no longer work sim/builder.hh: remove some extra variables since they are found in the ConfigNode sim/main.cc: add a quick hack command line argument -X to dump out the embedded files. (probably should be fixed up a little.) accept .mpy files printing to the streams has to happen after the hierarchy is built since we're moving away from param contexts sim/param.cc: add parsing support for ranges sim/process.cc: isValid isn't very useful anymore. interpret the names stdout, stderr, cout, cerr for the file descriptors sim/pyconfig/SConscript: Add Action handlers for creating an embedded python file and for creating an embedded C file. use these action handlers to embed all objects found in the objects tree into the binary along with the importer and the m5config stuff sim/pyconfig/m5config.py: Major changes to the original configuration file generator. These changes largely involve implementing copy-on-write like semantics for all of the SimObjects. Real documentation must be written. sim/universe.cc: Universe becomes a SimObject since we don't really have the notion of param contexts in the python code. --HG-- rename : sim/pyconfig/m5configbase.py => sim/pyconfig/m5config.py extra : convert_revision : c353453e5beb91c37f15755998fc0d8858c6829a
2004-11-13Use parameter structs for initialization so it's easierNathan Binkert
to add new devices. Abstract the Platform more so that it is unnecessary to know know platform specifics for interrupting or translating PCI DMA addresses. dev/ide_ctrl.cc: convert to parameter struct for initialization use the interrupt functions in the PciDev base class convert from tsunami to using platform We don't need an interrupt controller here. dev/ide_ctrl.hh: don't use Tsunami, use Platform make the IdeDisk a friend so that it can access my plaform convert to parameter struct for construction dev/ide_disk.cc: don't use tsunami references, but platform references dev/ns_gige.cc: Convert to parameter struct for initialzation. Use code in base class for interrupts so we don't need to know anything about the platform. Don't need an IntrControl *. dev/ns_gige.hh: We don't need a Tsunami * anymore convert to a parameter struct for construction dev/pcidev.cc: deal with new parameter struct dev/pcidev.hh: - Move all of the configuration parameters into a param struct that we can pass into the constructor. - Add a Platform * for accessing new generic interrupt post/clear and dma address translation fuctions - Create functions for posting/clearing interrupts and translating dma addresses dev/platform.cc: have default functions that panic on pci calls dev/platform.hh: don't make the pci stuff pure virtual, but rather provide default implementations that panic. Also, add dma address translation. dev/tsunami.cc: this-> isn't necessary here. add pci address translation dev/tsunami.hh: implement the pciToDma address translation --HG-- extra : convert_revision : 7db27a2fa1f1bd84704921ec7ca0280b5653c43e
