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.
2014-10-16arch: Use shared_ptr for all FaultsAndreas Hansson
This patch takes quite a large step in transitioning from the ad-hoc RefCountingPtr to the c++11 shared_ptr by adopting its use for all Faults. There are no changes in behaviour, and the code modifications are mostly just replacing "new" with "make_shared".
2012-02-11SPARC: Make PSTATE and HPSTATE a BitUnion.Gabe Black
This gets rid of cryptic bits of code with lots of bit manipulation, and makes some comments redundant.
2011-04-15trace: reimplement the DTRACE function so it doesn't use a vectorNathan Binkert
At the same time, rename the trace flags to debug flags since they have broader usage than simply tracing. This means that --trace-flags is now --debug-flags and --trace-help is now --debug-help

CPU->checkInterrupts bool is inconsistent, and i think should eventually be phased out. For now, I've just assumed that CPU->checkInterrupts() is the way to fast path a CPU if you have no interrupts by having a simple bitfield in each ISA to determine whether interrupts are pending. getInterrupts has been mostly filled in. src/arch/sparc/interrupts.hh: fill in how we do interrupts on sparc a little bit. 1) create a bitfield for interrupts, and check that in checkInterrupts() to fast path CPU. 2) fill in getInterrupts() a little bit. also, update the bitfield access to be HPSTATE::hpriv, etc. src/arch/sparc/ua2005.cc: 1) update formatting 2) change the way interrupts are done to use the new way to tickle the CPU. src/cpu/base.cc: src/cpu/base.hh: overload the post_interrupt function for SPARC interrupts - which are only denoted by a single int value. --HG-- extra : convert_revision : 9074a003eff37a40dcce78f56d20f6cbcc453eb5
