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.
2012-04-25MEM: Add the PortId type and a corresponding id field to PortAndreas Hansson
This patch introduces the PortId type, moves the definition of INVALID_PORT_ID to the Port class, and also gives every port an id to reflect the fact that each element in a vector port has an identifier/index. Previously the bus and Ruby testers (and potentially other users of the vector ports) added the id field in their port subclasses, and now this functionality is always present as it is moved to the base class.
2012-04-15CPU: Tidy up some formatting and a DPRINTF in the simple CPU base class.Gabe Black
Put the { on the same line as the if and put a space between the if and the open paren. Also, use the # format modifier which puts a 0x in front of hex values automatically. If the ExtMachInst type isn't integral and actually prints something more complicated, the # falls away harmlessly and we aren't left with a phantom 0x followed by a bunch of unrelated text.
2012-04-14Ruby: Use MasterPort base-class pointers where possibleAndreas Hansson
This patch simplifies future patches by changing the pointer type used in a number of the Ruby testers to use MasterPort instead of using a derived CpuPort class. There is no reason for using the more specialised pointers, and there is no longer a need to do any casting. With the latest changes to the tester, organising ports as readers and writes, things got a bit more complicated, and the "type" now had to be removed to be able to fall back to using MasterPort rather than CpuPort.
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".

2012-04-06rubytest: seperated read and write ports.Brad Beckmann
This patch allows the ruby tester to support protocols where the i-cache and d-cache are managed by seperate controllers.
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
2012-04-05NetworkTest: remove unnecessary memory allocationTushar Krishna
2012-04-03Atomic: Remove the physmem_port and access memory directlyAndreas Hansson
This patch removes the physmem_port from the Atomic CPU and instead uses the system pointer to access the physmem when using the fastmem option. The system already keeps track of the physmem and the valid memory address ranges, and with this patch we merely make use of that existing functionality. As a result of this change, the overloaded getMasterPort in the Atomic CPU can be removed, thus unifying the CPUs.
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.
2012-03-22Scons: Remove Werror=False in SConscript filesAndreas Hansson
This patch removes the overriding of "-Werror" in a handful of cases. The code compiles with gcc 4.6.3 and clang 3.0 without any warnings, and thus without any errors. There are no functional changes introduced by this patch. In the future, rather than ypassing "-Werror", address the warnings.

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).
2012-03-19clang: Fix recently introduced clang compilation errorsAndreas Hansson
This patch makes the code compile with clang 2.9 and 3.0 again by making two very minor changes. Firt, it maintains a strict typing in the forward declaration of the BaseCPUParams. Second, it adds a FullSystemInt flag of the type unsigned int next to the boolean FullSystem flag. The FullSystemInt variable can be used in decode-statements (expands to switch statements) in the instruction decoder.

2012-03-09O3/Ozone: Eliminate dead code counting software prefetch instsGeoffrey Blake
Eliminates dead code in the O3 and Ozone CPU models that counted software prefetch instructions separately for the ALPHA ISA only.
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.
2012-03-09CheckerCPU: Make CheckerCPU runtime selectable instead of compile selectableGeoffrey Blake
Enables the CheckerCPU to be selected at runtime with the --checker option from the configs/example/fs.py and configs/example/se.py configuration files. Also merges with the SE/FS changes.
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.
2012-03-01x86: Fix switching of CPUsNilay Vaish
This patch prevents creation of interrupt controller for cpus that will be switched in later
2012-02-24Ruby: Simplify tester ports by not using SimpleTimingPortAndreas Hansson
This patch simplfies the master ports used by RubyDirectedTester and RubyTester by avoiding the use of SimpleTimingPort. Neither tester made any use of the functionality offered by SimpleTimingPort besides a trivial implementation of recvFunctional (only snoops) and recvRangeChange (not relevant since there is only one master). The patch does not change or add any functionality, it merely makes the introduction of a master/slave port easier (in a future patch).
2012-02-24MEM: Move all read/write blob functions from Port to PortProxyAndreas Hansson
This patch moves the readBlob/writeBlob/memsetBlob from the Port class to the PortProxy class, thus making a clear separation of the basic port functionality (recv/send functional/atomic/timing), and the higher-level functional accessors available on the port proxies. There are only a few places in the code base where the blob functions were used on ports, and they are all for peeking into the memory system without making a normal memory access (in the memtest, and the malta and tsunami pchip). The memtest also exemplifies how easy it is to create a non-translating proxy if desired. The malta and tsunami pchip used a slave port to perform a functional read, and this is now changed to rely on the physProxy of the system (to which they already have a pointer).
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.
2012-02-24MEM: Move port creation to the memory object(s) constructionAndreas Hansson
This patch moves all port creation from the getPort method to be consistently done in the MemObject's constructor. This is possible thanks to the Swig interface passing the length of the vector ports. Previously there was a mix of: 1) creating the ports as members (at object construction time) and using getPort for the name resolution, or 2) dynamically creating the ports in the getPort call. This is now uniform. Furthermore, objects that would not be complete without a port have these ports as members rather than having pointers to dynamically allocated ports. This patch also enables an elaboration-time enumeration of all the ports in the system which can be used to determine the masterId.
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.
2012-02-13BPred: Fix RAS to handle predicated call/return instructions.Mrinmoy Ghosh
Change RAS to fix issues with predicated call/return instructions. Handled all cases in the life of a predicated call and return instruction.
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
2012-02-13MEM: Introduce the master/slave port roles in the Python classesAndreas Hansson
This patch classifies all ports in Python as either Master or Slave and enforces a binding of master to slave. Conceptually, a master (such as a CPU or DMA port) issues requests, and receives responses, and conversely, a slave (such as a memory or a PIO device) receives requests and sends back responses. Currently there is no differentiation between coherent and non-coherent masters and slaves. The classification as master/slave also involves splitting the dual role port of the bus into a master and slave port and updating all the system assembly scripts to use the appropriate port. Similarly, the interrupt devices have to have their int_port split into a master and slave port. The intdev and its children have minimal changes to facilitate the extra port. Note that this patch does not enforce any port typing in the C++ world, it merely ensures that the Python objects have a notion of the port roles and are connected in an appropriate manner. This check is carried when two ports are connected, e.g. bus.master = memory.port. The following patches will make use of the classifications and specialise the C++ ports into masters and slaves.
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.
2012-02-10O3 CPU: Improve handling of delayed commit flagNilay Vaish
The delayed commit flag is used in conjunction with interrupt pending flag to figure out whether or not fetch stage should get more instructions. This patch clears this flag when instructions are squashed. Also, in case an interrupt is pending, currently it is not possible to access the instruction cache. This patch allows accessing the cache in case this flag is set.
2012-02-10O3 CPU: Strengthen condition for handling interruptsNilay Vaish
The condition for handling interrupts is to check whether or not the cpu's instruction list is empty. As observed, this can lead to cases in which even though the instruction list is empty, interrupts are handled when they should not be. The condition is being strengthened so that interrupts get handled only when the last committed microop did not had IsDelayedCommit set.
2012-02-10O3 CPU: Provide the squashing instructionNilay Vaish
This patch adds a function to the ROB that will get the squashing instruction from the ROB's list of instructions. This squashing instruction is used for figuring out the macroop from which the fetch stage should fetch the microops. Further, a check has been added that if the instructions are to be fetched from the cache maintained by the fetch stage, then the data in the cache should be valid and the PC of the thread being fetched from is same as the address of the cache block.

2012-02-10SE/FS: Record the system pointer all the time for the simple CPU.Gabe Black
This pointer was only being stored in code that came from SE mode. The system pointer is always meaningful and available, so it should always be stored.
2012-02-07Checker: Access workload element 0 only if there is an element 0.Gabe Black
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.
2012-01-31Thread: Use inherited baseCpu rather than cpu in SimpleThreadAndreas Hansson
This patch is a trivial simplification, removing the cpu pointer from SimpleThread and relying on the baseCpu pointer in ThreadState. The patch does not add or change any functionality, it merely cleans up the code.
2012-01-31CheckerCPU: Re-factor CheckerCPU to be compatible with current gem5Geoffrey Blake
Brings the CheckerCPU back to life to allow FS and SE checking of the O3CPU. These changes have only been tested with the ARM ISA. Other ISAs potentially require modification.

2012-01-30MEM: Clean-up of Functional/Virtual/TranslatingPort remnantsAndreas Hansson
