2013-01-07cpu: Rename defer_registration->switched_outAndreas Sandberg
The defer_registration parameter is used to prevent a CPU from initializing at startup, leaving it in the "switched out" mode. The name of this parameter (and the help string) is confusing. This patch renames it to switched_out, which should be more descriptive.
2013-01-07cpu: Remove unused params.hh header file in inorder CPUAndreas Sandberg
2013-01-07cpu: Unify SimpleCPU and O3 CPU serialization codeAndreas Sandberg
The O3 CPU used to copy its thread context to a SimpleThread in order to do serialization. This was a bit of a hack involving two static SimpleThread instances and a magic constructor that was only used by the O3 CPU. This patch moves the ThreadContext serialization code into two global procedures that, in addition to the normal serialization parameters, take a ThreadContext reference as a parameter. This allows us to reuse the serialization code in all ThreadContext implementations.
2013-01-07cpu: Implement a flat register interface in thread contextsAndreas Sandberg
Some architectures map registers differently depending on their mode of operations. There is currently no architecture independent way of accessing all registers. This patch introduces a flat register interface to the ThreadContext class. This interface is useful, for example, when serializing or copying thread contexts.
2013-01-07cpu: Check that the memory system is in the correct modeAndreas Sandberg
This patch adds checks to all CPU models to make sure that the memory system is in the correct mode at startup and when resuming after a drain. Previously, we only checked that the memory system was in the right mode when resuming. This is inadequate since this is a configuration error that should be detected at startup as well as when resuming. Additionally, since the check was done using an assert, it wasn't performed when NDEBUG was set (e.g., the fast target).
2013-01-07arch: Make the ISA class inherit from SimObjectAndreas Sandberg
The ISA class on stores the contents of ID registers on many architectures. In order to make reset values of such registers configurable, we make the class inherit from SimObject, which allows us to use the normal generated parameter headers. This patch introduces a Python helper method, BaseCPU.createThreads(), which creates a set of ISAs for each of the threads in an SMT system. Although it is currently only needed when creating multi-threaded CPUs, it should always be called before instantiating the system as this is an obvious place to configure ID registers identifying a thread/CPU.
2013-01-07cpu: rename the misleading inSyscall to noSquashFromTCAli Saidi
isSyscall was originally created because during handling of a syscall in SE mode the threadcontext had to be updated. However, in many places this is used in FS mode (e.g. fault handlers) and the name doesn't make much sense. The boolean actually stops gem5 from squashing speculative and non-committed state when a write to a threadcontext happens, so re-name the variable to something more appropriate
2013-01-04Decoder: Remove the thread context get/set from the decoder.Gabe Black
This interface is no longer used, and getting rid of it simplifies the decoders and code that sets up the decoders. The thread context had been used to read architectural state which was used to contextualize the instruction memory as it came in. That was changed so that the state is now sent to the decoders to keep locally if/when it changes. That's significantly more efficient. Committed by: Nilay Vaish <nilay@cs.wisc.edu>
2012-12-06TournamentBP: Fix some bugs with table sizes and countersErik Tomusk
globalHistoryBits, globalPredictorSize, and choicePredictorSize are decoupled. globalHistoryBits controls how much history is kept, global and choice predictor sizes control how much of that history is used when accessing predictor tables. This way, global and choice predictors can actually be different sizes, and it is no longer possible to walk off the predictor arrays and cause a seg fault. There are now individual thresholds for choice, global, and local saturating counters, so that taken/not taken decisions are correct even when the predictors' counters' sizes are different. The interface for localPredictorSize has been removed from TournamentBP because the value can be calculated from localHistoryBits. Committed by: Nilay Vaish <nilay@cs.wisc.edu>

2012-11-02sim: Include object header files in SWIG interfacesAndreas Sandberg
When casting objects in the generated SWIG interfaces, SWIG uses classical C-style casts ( (Foo *)bar; ). In some cases, this can degenerate into the equivalent of a reinterpret_cast (mainly if only a forward declaration of the type is available). This usually works for most compilers, but it is known to break if multiple inheritance is used anywhere in the object hierarchy. This patch introduces the cxx_header attribute to Python SimObject definitions, which should be used to specify a header to include in the SWIG interface. The header should include the declaration of the wrapped object. We currently don't enforce header the use of the header attribute, but a warning will be generated for objects that do not use it.
2012-09-07Param: Transition to Cycles for relevant parametersAndreas Hansson
This patch is a first step to using Cycles as a parameter type. The main affected modules are the CPUs and the Ruby caches. There are definitely plenty more places that are affected, but this patch serves as a starting point to making the transition. An important part of this patch is to actually enable parameters to be specified as Param.Cycles which involves some changes to params.py.
2012-08-28Clock: Add a Cycles wrapper class and use where applicableAndreas Hansson
This patch addresses the comments and feedback on the preceding patch that reworks the clocks and now more clearly shows where cycles (relative cycle counts) are used to express time. Instead of bumping the existing patch I chose to make this a separate patch, merely to try and focus the discussion around a smaller set of changes. The two patches will be pushed together though. This changes done as part of this patch are mostly following directly from the introduction of the wrapper class, and change enough code to make things compile and run again. There are definitely more places where int/uint/Tick is still used to represent cycles, and it will take some time to chase them all down. Similarly, a lot of parameters should be changed from Param.Tick and Param.Unsigned to Param.Cycles. In addition, the use of curTick is questionable as there should not be an absolute cycle. Potential solutions can be built on top of this patch. There is a similar situation in the o3 CPU where lastRunningCycle is currently counting in Cycles, and is still an absolute time. More discussion to be had in other words. An additional change that would be appropriate in the future is to perform a similar wrapping of Tick and probably also introduce a Ticks class along with suitable operators for all these classes.
2012-08-28Clock: Rework clocks to avoid tick-to-cycle transformationsAndreas Hansson
This patch introduces the notion of a clock update function that aims to avoid costly divisions when turning the current tick into a cycle. Each clocked object advances a private (hidden) cycle member and a tick member and uses these to implement functions for getting the tick of the next cycle, or the tick of a cycle some time in the future. In the different modules using the clocks, changes are made to avoid counting in ticks only to later translate to cycles. There are a few oddities in how the O3 and inorder CPU count idle cycles, as seen by a few locations where a cycle is subtracted in the calculation. This is done such that the regression does not change any stats, but should be revisited in a future patch. Another, much needed, change that is not done as part of this patch is to introduce a new typedef uint64_t Cycle to be able to at least hint at the unit of the variables counting Ticks vs Cycles. This will be done as a follow-up patch. As an additional follow up, the thread context still uses ticks for the book keeping of last activate and last suspend and this should probably also be changed into cycles as well.
2012-08-21CPU: Remove overloaded function_trace_start parameterAndreas Hansson
This patch removes the overloading of the parameter, which seems both redundant, and possibly incorrect. The inorder CPU is particularly interesting as it uses a different name for the parameter, and never make any use of it internally.
2012-08-06process: add progName() virtual functionSteve Reinhardt
This replaces a (potentially uninitialized) string field with a virtual function so that we can have a safe interface without requiring changes to the eio code.
2012-07-09Port: Align port names in C++ and PythonAndreas Hansson
This patch is a first step to align the port names used in the Python world and the C++ world. Ultimately it serves to make the use of config.json together with output from the simulation easier, including post-processing of statistics. Most notably, the CPU, cache, and bus is addressed in this patch, and there might be other ports that should be updated accordingly. The dash name separator has also been replaced with a "." which is what is used to concatenate the names in python, and a separation is made between the master and slave port in the bus.
2012-06-05cpu: Don't init simple and inorder CPUs if they are defered.Anthony Gutierrez
initCPU() will be called to initialize switched out CPUs for the simple and inorder CPU models. this patch prevents those CPUs from being initialized because they should get their state from the active CPU when it is switched out.
2012-06-05sim: Remove FastAllocAli Saidi
While FastAlloc provides a small performance increase (~1.5%) over regular malloc it isn't thread safe. After removing FastAlloc and using tcmalloc I've seen a performance increase of 12% over libc malloc when running twolf for ARM.
2012-05-26CPU: Merge the predecoder and decoder.Gabe Black
These classes are always used together, and merging them will give the ISAs more flexibility in how they cache things and manage the process. --HG-- rename : src/arch/x86/predecoder_tables.cc => src/arch/x86/decoder_tables.cc

2012-05-01MEM: Separate requests and responses for timing accessesAndreas Hansson
This patch moves send/recvTiming and send/recvTimingSnoop from the Port base class to the MasterPort and SlavePort, and also splits them into separate member functions for requests and responses: send/recvTimingReq, send/recvTimingResp, and send/recvTimingSnoopReq, send/recvTimingSnoopResp. A master port sends requests and receives responses, and also receives snoop requests and sends snoop responses. A slave port has the reciprocal behaviour as it receives requests and sends responses, and sends snoop requests and receives snoop responses. For all MemObjects that have only master ports or slave ports (but not both), e.g. a CPU, or a PIO device, this patch merely adds more clarity to what kind of access is taking place. For example, a CPU port used to call sendTiming, and will now call sendTimingReq. Similarly, a response previously came back through recvTiming, which is now recvTimingResp. For the modules that have both master and slave ports, e.g. the bus, the behaviour was previously relying on branches based on pkt->isRequest(), and this is now replaced with a direct call to the apprioriate member function depending on the type of access. Please note that send/recvRetry is still shared by all the timing accessors and remains in the Port base class for now (to maintain the current bus functionality and avoid changing the statistics of all regressions). The packet queue is split into a MasterPort and SlavePort version to facilitate the use of the new timing accessors. All uses of the PacketQueue are updated accordingly. With this patch, the type of packet (request or response) is now well defined for each type of access, and asserts on pkt->isRequest() and pkt->isResponse() are now moved to the appropriate send member functions. It is also worth noting that sendTimingSnoopReq no longer returns a boolean, as the semantics do not alow snoop requests to be rejected or stalled. All these assumptions are now excplicitly part of the port interface itself.
2012-04-14MEM: Remove the Broadcast destination from the packetAndreas Hansson
This patch simplifies the packet by removing the broadcast flag and instead more firmly relying on (and enforcing) the semantics of transactions in the classic memory system, i.e. request packets are routed from a master to a slave based on the address, and when they are created they have neither a valid source, nor destination. On their way to the slave, the request packet is updated with a source field for all modules that multiplex packets from multiple master (e.g. a bus). When a request packet is turned into a response packet (at the final slave), it moves the potentially populated source field to the destination field, and the response packet is routed through any multiplexing components back to the master based on the destination field. Modules that connect multiplexing components, such as caches and bridges store any existing source and destination field in the sender state as a stack (just as before). The packet constructor is simplified in that there is no longer a need to pass the Packet::Broadcast as the destination (this was always the case for the classic memory system). In the case of Ruby, rather than using the parameter to the constructor we now rely on setDest, as there is already another three-argument constructor in the packet class. In many places where the packet information was printed as part of DPRINTFs, request packets would be printed with a numeric "dest" that would always be -1 (Broadcast) and that field is now removed from the printing.
2012-04-14MEM: Separate snoops and normal memory requests/responsesAndreas Hansson
This patch introduces port access methods that separates snoop request/responses from normal memory request/responses. The differentiation is made for functional, atomic and timing accesses and builds on the introduction of master and slave ports. Before the introduction of this patch, the packets belonging to the different phases of the protocol (request -> [forwarded snoop request -> snoop response]* -> response) all use the same port access functions, even though the snoop packets flow in the opposite direction to the normal packet. That is, a coherent master sends normal request and receives responses, but receives snoop requests and sends snoop responses (vice versa for the slave). These two distinct phases now use different access functions, as described below. Starting with the functional access, a master sends a request to a slave through sendFunctional, and the request packet is turned into a response before the call returns. In a system without cache coherence, this is all that is needed from the functional interface. For the cache-coherent scenario, a slave also sends snoop requests to coherent masters through sendFunctionalSnoop, with responses returned within the same packet pointer. This is currently used by the bus and caches, and the LSQ of the O3 CPU. The send/recvFunctional and send/recvFunctionalSnoop are moved from the Port super class to the appropriate subclass. Atomic accesses follow the same flow as functional accesses, with request being sent from master to slave through sendAtomic. In the case of cache-coherent ports, a slave can send snoop requests to a master through sendAtomicSnoop. Just as for the functional access methods, the atomic send and receive member functions are moved to the appropriate subclasses. The timing access methods are different from the functional and atomic in that requests and responses are separated in time and send/recvTiming are used for both directions. Hence, a master uses sendTiming to send a request to a slave, and a slave uses sendTiming to send a response back to a master, at a later point in time. Snoop requests and responses travel in the opposite direction, similar to what happens in functional and atomic accesses. With the introduction of this patch, it is possible to determine the direction of packets in the bus, and no longer necessary to look for both a master and a slave port with the requested port id. In contrast to the normal recvFunctional, recvAtomic and recvTiming that are pure virtual functions, the recvFunctionalSnoop, recvAtomicSnoop and recvTimingSnoop have a default implementation that calls panic. This is to allow non-coherent master and slave ports to not implement these functions.
2012-04-14clang/gcc: Fix compilation issues with clang 3.0 and gcc 4.6Andreas Hansson
This patch addresses a number of minor issues that cause problems when compiling with clang >= 3.0 and gcc >= 4.6. Most importantly, it avoids using the deprecated ext/hash_map and instead uses unordered_map (and similarly so for the hash_set). To make use of the new STL containers, g++ and clang has to be invoked with "-std=c++0x", and this is now added for all gcc versions >= 4.6, and for clang >= 3.0. For gcc >= 4.3 and <= 4.5 and clang <= 3.0 we use the tr1 unordered_map to avoid the deprecation warning. The addition of c++0x in turn causes a few problems, as the compiler is more stringent and adds a number of new warnings. Below, the most important issues are enumerated: 1) the use of namespaces is more strict, e.g. for isnan, and all headers opening the entire namespace std are now fixed. 2) another other issue caused by the more stringent compiler is the narrowing of the embedded python, which used to be a char array, and is now unsigned char since there were values larger than 128. 3) a particularly odd issue that arose with the new c++0x behaviour is found in range.hh, where the operator< causes gcc to complain about the template type parsing (the "<" is interpreted as the beginning of a template argument), and the problem seems to be related to the begin/end members introduced for the range-type iteration, which is a new feature in c++11. As a minor update, this patch also fixes the build flags for the clang debug target that used to be shared with gcc and incorrectly use "-ggdb".
2012-04-06MEM: Enable multiple distributed generalized memoriesAndreas Hansson
This patch removes the assumption on having on single instance of PhysicalMemory, and enables a distributed memory where the individual memories in the system are each responsible for a single contiguous address range. All memories inherit from an AbstractMemory that encompasses the basic behaviuor of a random access memory, and provides untimed access methods. What was previously called PhysicalMemory is now SimpleMemory, and a subclass of AbstractMemory. All future types of memory controllers should inherit from AbstractMemory. To enable e.g. the atomic CPU and RubyPort to access the now distributed memory, the system has a wrapper class, called PhysicalMemory that is aware of all the memories in the system and their associated address ranges. This class thus acts as an infinitely-fast bus and performs address decoding for these "shortcut" accesses. Each memory can specify that it should not be part of the global address map (used e.g. by the functional memories by some testers). Moreover, each memory can be configured to be reported to the OS configuration table, useful for populating ATAG structures, and any potential ACPI tables. Checkpointing support currently assumes that all memories have the same size and organisation when creating and resuming from the checkpoint. A future patch will enable a more flexible re-organisation. --HG-- rename : src/mem/PhysicalMemory.py => src/mem/AbstractMemory.py rename : src/mem/PhysicalMemory.py => src/mem/SimpleMemory.py rename : src/mem/physical.cc => src/mem/abstract_mem.cc rename : src/mem/physical.hh => src/mem/abstract_mem.hh rename : src/mem/physical.cc => src/mem/simple_mem.cc rename : src/mem/physical.hh => src/mem/simple_mem.hh
2012-03-30MEM: Introduce the master/slave port sub-classes in C++William Wang
This patch introduces the notion of a master and slave port in the C++ code, thus bringing the previous classification from the Python classes into the corresponding simulation objects and memory objects. The patch enables us to classify behaviours into the two bins and add assumptions and enfore compliance, also simplifying the two interfaces. As a starting point, isSnooping is confined to a master port, and getAddrRanges to slave ports. More of these specilisations are to come in later patches. The getPort function is not getMasterPort and getSlavePort, and returns a port reference rather than a pointer as NULL would never be a valid return value. The default implementation of these two functions is placed in MemObject, and calls fatal. The one drawback with this specific patch is that it requires some code duplication, e.g. QueuedPort becomes QueuedMasterPort and QueuedSlavePort, and BusPort becomes BusMasterPort and BusSlavePort (avoiding multiple inheritance). With the later introduction of the port interfaces, moving the functionality outside the port itself, a lot of the duplicated code will disappear again.
2012-03-30CPU: Unify initMemProxies across CPUs and simulation modesAndreas Hansson
This patch unifies where initMemProxies is called, in the init() method of each BaseCPU subclass, before TheISA::initCPU is called. Moreover, it also ensures that initMemProxies is called in both full-system and syscall-emulation mode, thus unifying also across the modes. An additional check is added in the ThreadState to ensure that initMemProxies is only called once.
2012-03-19gcc: Clean-up of non-C++0x compliant code, first stepsAndreas Hansson
This patch cleans up a number of minor issues aiming to get closer to compliance with the C++0x standard as interpreted by gcc and clang (compile with std=c++0x and -pedantic-errors). In particular, the patch cleans up enums where the last item was succeded by a comma, namespaces closed by a curcly brace followed by a semi-colon, and the use of the GNU-extension typeof (replaced by templated functions). It does not address variable-length arrays, zero-size arrays, anonymous structs, range expressions in switch statements, and the use of long long. The generated CPU code also has a large number of issues that remain to be fixed, mainly related to overflows in implicit constant conversion (due to shifts).
2012-03-09CheckerCPU: Add function stubs to non-ARM ISA source to compile with CheckerCPUGeoffrey Blake
Making the CheckerCPU a runtime time option requires the code to be compatible with ISAs other than ARM. This patch adds the appropriate function stubs to allow compilation.
2012-03-02DynInst: get rid of dead MyHash code.Steve Reinhardt
Not sure what this was ever used for, but it doesn't seem used anymore.
2012-03-02CPU: Check that the interrupt controller is created when neededAndreas Hansson
This patch adds a creation-time check to the CPU to ensure that the interrupt controller is created for the cases where it is needed, i.e. if the CPU is not being switched in later and not a checker CPU. The patch also adds the "createInterruptController" call to a number of the regression scripts.
2012-02-24MEM: Make port proxies use references rather than pointersAndreas Hansson
This patch is adding a clearer design intent to all objects that would not be complete without a port proxy by making the proxies members rathen than dynamically allocated. In essence, if NULL would not be a valid value for the proxy, then we avoid using a pointer to make this clear. The same approach is used for the methods using these proxies, such as loadSections, that now use references rather than pointers to better reflect the fact that NULL would not be an acceptable value (in fact the code would break and that is how this patch started out). Overall the concept of "using a reference to express unconditional composition where a NULL pointer is never valid" could be done on a much broader scale throughout the code base, but for now it is only done in the locations affected by the proxies.
2012-02-24CPU: Round-two unifying instr/data CPU ports across modelsAndreas Hansson
This patch continues the unification of how the different CPU models create and share their instruction and data ports. Most importantly, it forces every CPU to have an instruction and a data port, and gives these ports explicit getters in the BaseCPU (getDataPort and getInstPort). The patch helps in simplifying the code, make assumptions more explicit, andfurther ease future patches related to the CPU ports. The biggest changes are in the in-order model (that was not modified in the previous unification patch), which now moves the ports from the CacheUnit to the CPU. It also distinguishes the instruction fetch and load-store unit from the rest of the resources, and avoids the use of indices and casting in favour of keeping track of these two units explicitly (since they are always there anyways). The atomic, timing and O3 model simply return references to their already existing ports.
2012-02-13BP: Fix several Branch Predictor issues.Mrinmoy Ghosh
1. Updates the Branch Predictor correctly to the state just after a mispredicted branch, if a squash occurs. 2. If a BTB does not find an entry, the branch is predicted not taken. The global history is modified to correctly reflect this prediction. 3. Local history is now updated at the fetch stage instead of execute stage. 4. In the Update stage of the branch predictor the local predictors are now correctly updated according to the state of local history during fetch stage. This patch also improves performance by as much as 17% on some benchmarks
2012-02-12cpu: add separate stats for insts/ops both globally and per cpu modelAnthony Gutierrez
2012-02-12mem: Add a master ID to each request object.Ali Saidi
This change adds a master id to each request object which can be used identify every device in the system that is capable of issuing a request. This is part of the way to removing the numCpus+1 stats in the cache and replacing them with the master ids. This is one of a series of changes that make way for the stats output to be changed to python.
2012-02-07Faults: Turn off arch/faults.hhGabe Black
Because there are no longer architecture independent but specialized functions in arch/XXX/faults.hh, code that isn't using the faults from a particular ISA no longer needs to be able to include them through the switching header file arch/faults.hh. By removing that header file (arch/faults.hh), the potential interface between ISA code and non ISA code is narrowed.

2012-01-31clang: Enable compiling gem5 using clang 2.9 and 3.0Koan-Sin Tan
This patch adds the necessary flags to the SConstruct and SConscript files for compiling using clang 2.9 and later (on Ubuntu et al and OSX XCode 4.2), and also cleans up a bunch of compiler warnings found by clang. Most of the warnings are related to hidden virtual functions, comparisons with unsigneds >= 0, and if-statements with empty bodies. A number of mismatches between struct and class are also fixed. clang 2.8 is not working as it has problems with class names that occur in multiple namespaces (e.g. Statistics in kernel_stats.hh). clang has a bug (http://llvm.org/bugs/show_bug.cgi?id=7247) which causes confusion between the container std::set and the function Packet::set, and this is currently addressed by not including the entire namespace std, but rather selecting e.g. "using std::vector" in the appropriate places.

2012-01-17MEM: Separate queries for snooping and address rangesAndreas Hansson
This patch simplifies the address-range determination mechanism and also unifies the naming across ports and devices. It further splits the queries for determining if a port is snooping and what address ranges it responds to (aiming towards a separation of cache-maintenance ports and pure memory-mapped ports). Default behaviours are such that most ports do not have to define isSnooping, and master ports need not implement getAddrRanges.
2012-01-17CPU: Moving towards a more general port across CPU modelsAndreas Hansson
This patch performs minimal changes to move the instruction and data ports from specialised subclasses to the base CPU (to the largest degree possible). Ultimately it servers to make the CPU(s) have a well-defined interface to the memory sub-system.
2012-01-17MEM: Add port proxies instead of non-structural portsAndreas Hansson
Port proxies are used to replace non-structural ports, and thus enable all ports in the system to correspond to a structural entity. This has the advantage of accessing memory through the normal memory subsystem and thus allowing any constellation of distributed memories, address maps, etc. Most accesses are done through the "system port" that is used for loading binaries, debugging etc. For the entities that belong to the CPU, e.g. threads and thread contexts, they wrap the CPU data port in a port proxy. The following replacements are made: FunctionalPort > PortProxy TranslatingPort > SETranslatingPortProxy VirtualPort > FSTranslatingPortProxy --HG-- rename : src/mem/vport.cc => src/mem/fs_translating_port_proxy.cc rename : src/mem/vport.hh => src/mem/fs_translating_port_proxy.hh rename : src/mem/translating_port.cc => src/mem/se_translating_port_proxy.cc rename : src/mem/translating_port.hh => src/mem/se_translating_port_proxy.hh
