2015-10-23x86: Add missing explicit overrides for X86 devicesAndreas Hansson
Make clang >= 3.5 happy when compiling build/X86/gem5.opt on OSX.
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.
2015-08-07dev, x86: Fix serialization bug in the i8042 deviceAndreas Sandberg
The i8042 device drops the contents of a PS2 device's buffer when serializing, which results in corrupted PS2 state when continuing simulation after a checkpoint. This changeset fixes this bug and transitions the i8042 model to use the new serialization API that requires the serialize() method to be const.
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.
2013-07-11dev: make BasicPioDevice take size in constructorSteve Reinhardt
Instead of relying on derived classes explicitly assigning to the BasicPioDevice pioSize field, require them to pass a size value in to the constructor. Committed by: Nilay Vaish <nilay@cs.wisc.edu>
2012-07-09Port: Make getAddrRanges constAndreas Hansson
This patch makes getAddrRanges const throughout the code base. There is no reason why it should not be, and making it const prevents adding any unintentional side-effects.
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.

2011-02-06x86: Add checkpointing capability to devicesJoel Hestness
Add checkpointing capability to the Intel 8254 timer, CMOS, I8042, PS2 Keyboard and Mouse, I82094AA, I8237, I8254, I8259, and speaker devices
2011-01-03Make commenting on close namespace brackets consistent.Steve Reinhardt
Ran all the source files through 'perl -pi' with this script: s|\s*(};?\s*)?/\*\s*(end\s*)?namespace\s*(\S+)\s*\*/(\s*})?|} // namespace $3|; s|\s*};?\s*//\s*(end\s*)?namespace\s*(\S+)\s*|} // namespace $2\n|; s|\s*};?\s*//\s*(\S+)\s*namespace\s*|} // namespace $1\n|; Also did a little manual editing on some of the arch/*/isa_traits.hh files and src/SConscript.
