2017-02-27syscall_emul: [PATCH 15/22] add clone/execve for threading and multiprocess ↵Brandon Potter
simulations Modifies the clone system call and adds execve system call. Requires allowing processes to steal thread contexts from other processes in the same system object and the ability to detach pieces of process state (such as MemState) to allow dynamic sharing.
2015-10-12misc: Remove redundant compiler-specific definesAndreas Hansson
This patch moves away from using M5_ATTR_OVERRIDE and the m5::hashmap (and similar) abstractions, as these are no longer needed with gcc 4.7 and clang 3.1 as minimum compiler versions.
2015-08-07base: Declare a type for context IDsAndreas Sandberg
Context IDs used to be declared as ad hoc (usually as int). This changeset introduces a typedef for ContextIDs and a constant for invalid context IDs.
2015-07-07sim: Refactor the serialization base classAndreas Sandberg
Objects that are can be serialized are supposed to inherit from the Serializable class. This class is meant to provide a unified API for such objects. However, so far it has mainly been used by SimObjects due to some fundamental design limitations. This changeset redesigns to the serialization interface to make it more generic and hide the underlying checkpoint storage. Specifically: * Add a set of APIs to serialize into a subsection of the current object. Previously, objects that needed this functionality would use ad-hoc solutions using nameOut() and section name generation. In the new world, an object that implements the interface has the methods serializeSection() and unserializeSection() that serialize into a named /subsection/ of the current object. Calling serialize() serializes an object into the current section. * Move the name() method from Serializable to SimObject as it is no longer needed for serialization. The fully qualified section name is generated by the main serialization code on the fly as objects serialize sub-objects. * Add a scoped ScopedCheckpointSection helper class. Some objects need to serialize data structures, that are not deriving from Serializable, into subsections. Previously, this was done using nameOut() and manual section name generation. To simplify this, this changeset introduces a ScopedCheckpointSection() helper class. When this class is instantiated, it adds a new /subsection/ and subsequent serialization calls during the lifetime of this helper class happen inside this section (or a subsection in case of nested sections). * The serialize() call is now const which prevents accidental state manipulation during serialization. Objects that rely on modifying state can use the serializeOld() call instead. The default implementation simply calls serialize(). Note: The old-style calls need to be explicitly called using the serializeOld()/serializeSectionOld() style APIs. These are used by default when serializing SimObjects. * Both the input and output checkpoints now use their own named types. This hides underlying checkpoint implementation from objects that need checkpointing and makes it easier to change the underlying checkpoint storage code.
2014-05-09cpu, arm: Allow the specification of a socket fieldAkash Bagdia
Allow the specification of a socket ID for every core that is reflected in the MPIDR field in ARM systems. This allows studying multi-socket / cluster systems with ARM CPUs.
2014-03-07cpu: Make CPU and ThreadContext getters constAndreas Hansson
This patch merely tidies up the CPU and ThreadContext getters by making them const where appropriate.
2012-07-10cpu: added assertions to ensure the correct proxies are usedBrad Beckmann
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).
2012-02-24MEM: 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.

2012-01-31Thread: Use inherited baseCpu rather than cpu in SimpleThreadAndreas Hansson

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.

2009-04-15ThreadState: initialize status to Halted in constructor.Steve Reinhardt
This provides a common initial status for all threads independent of CPU model (unlike the prior situation where CPUs initialized threads to inconsistent states). This mostly matters for SE mode; in FS mode, ISA-specific startupCPU() methods generally handle boot-time initialization of thread contexts (since the right thing to do is ISA-dependent).

redundancies with threadId() as their replacement.
2008-11-02Add in Context IDs to the simulator. From now on, cpuId is almost never used,Lisa Hsu
the primary identifier for a hardware context should be contextId(). The concept of threads within a CPU remains, in the form of threadId() because sometimes you need to know which context within a cpu to manipulate.
2008-11-02make BaseCPU the provider of _cpuId, and cpuId() instead of being scatteredLisa Hsu
across the subclasses. generally make it so that member data is _cpuId and accessor functions are cpuId(). The ID val comes from the python (default -1 if none provided), and if it is -1, the index of cpuList will be given. this has passed util/regress quick and se.py -n4 and fs.py -n4 as well as standard switch.

a newly created one can.
2006-11-29Change the connecting of the physPort and virtPort to the memory object ↵Kevin Lim
below the CPU to happen every time activateContext is called. The overhead is probably a little higher than necessary, but allows these connections to properly be made when there are CPUs that are inactive until they are switched in. Right now this introduces a minor memory leak as old physPorts and virtPorts are not deleted when new ones are created. A flyspray task has been created for this issue. It can not be resolved until we determine how the bus will handle giving out ID's to functional ports that may be deleted. src/cpu/o3/cpu.cc: src/cpu/simple/atomic.cc: src/cpu/simple/timing.cc: Change the setup of the physPort and virtPort to instead happen every time the CPU has a context activated. This is a little high overhead, but keeps it working correctly when the CPU does not have a physical memory attached to it until it switches in (like the case of switch CPUs). src/cpu/o3/thread_context.hh: Change function from being called at init() to just being called whenever the memory ports need to be connected. src/cpu/o3/thread_context_impl.hh: Update this to not delete the port if it's the same as the virtPort. src/cpu/thread_context.hh: Change function from being called at init() to whenever the memory ports need to be connected. src/cpu/thread_state.cc: Instead of initializing the ports, simply connect them, deleting any old ports that might exist.

order to clear up the confusion due to the many ExecContexts. It also derives from a common ThreadState object, which holds various state common to threads across CPU models. Following with the previous check-in, ExecContext now refers only to the interface provided to the ISA in order to access CPU state. ThreadContext refers to the interface provided to all objects outside the CPU in order to access thread state. SimpleThread provides all thread state and the interface to access it, and is suitable for simple execution models such as the SimpleCPU. src/SConscript: Include thread state file. src/arch/alpha/ev5.cc: src/cpu/checker/cpu.cc: src/cpu/checker/cpu.hh: src/cpu/checker/thread_context.hh: src/cpu/memtest/memtest.cc: src/cpu/memtest/memtest.hh: src/cpu/o3/cpu.cc: src/cpu/ozone/cpu_impl.hh: src/cpu/simple/atomic.cc: src/cpu/simple/base.cc: src/cpu/simple/base.hh: src/cpu/simple/timing.cc: Rename CPUExecContext to SimpleThread. src/cpu/base_dyn_inst.hh: Make thread member variables protected.. src/cpu/o3/alpha_cpu.hh: src/cpu/o3/cpu.hh: Make various members of ThreadState protected. src/cpu/o3/alpha_cpu_impl.hh: Push generation of TranslatingPort into the CPU itself. Make various members of ThreadState protected. src/cpu/o3/thread_state.hh: Pull a lot of common code into the base ThreadState class. src/cpu/ozone/thread_state.hh: Rename CPUExecContext to SimpleThread, move a lot of common code into base ThreadState class. src/cpu/thread_state.hh: Push a lot of common code into base ThreadState class. This goes along with renaming CPUExecContext to SimpleThread, and making it derive from ThreadState. src/cpu/simple_thread.cc: Rename CPUExecContext to SimpleThread, make it derive from ThreadState. This helps push a lot of common code/state into a single class that can be used by all CPUs. src/cpu/simple_thread.hh: Rename CPUExecContext to SimpleThread, make it derive from ThreadState. src/kern/system_events.cc: Rename cpu_exec_context to thread_context. src/sim/process.hh: Remove unused forward declaration. --HG-- rename : src/cpu/cpu_exec_context.cc => src/cpu/simple_thread.cc rename : src/cpu/cpu_exec_context.hh => src/cpu/simple_thread.hh extra : convert_revision : 2ed617aa80b64016cb9270f75352607cca032733
