f0d1a20971 PCI: Add some missing breaks to a couple case statements. 2008-12-15 00:47:01 -08:00
Author Name
13f7fdcf67 The ide_ctrl serialize and unserialize were broken. 
Multiple channels were saving their state under the
same name. This patch separates the saved state of
the primary and secondary channel.

d857faf073 Add in Context IDs to the simulator. From now on, cpuId is almost never used, 
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.

119e127d71 X86: Create the IntDev and IntPin system. 
The IntDev class is a base for anything that supports IntPins. IntPins allow
devices to generically trigger interrupts on a particular pin of an IntDev
device without having to know what the device is or what pin they're attached
to.

94b08bed07 SimObjects: Clean up handling of C++ namespaces. 
Make them easier to express by only having the cxx_type parameter which
has the full namespace name, and drop the cxx_namespace thing.

80d9be86e6 gcc: Add extra parens to quell warnings. 
Even though we're not incorrect about operator precedence, let's add
some parens in some particularly confusing places to placate GCC 4.3
so that we don't have to turn the warning off.  Agreed that this is a
bit of a pain for those users who get the order of operations correct,
but it is likely to prevent bugs in certain cases.

ce3d8c2b03 atomicio: provide atomic read and write functions. 
These functions keep trying to read and write until all data has been
transferred, or an error occurrs.  In the case where an end of file
hasn't been reached, but all of the bytes have not been read/written,
try again.  On EINTR, try again.

50ef39af82 sockets: Add a function to disable all listening sockets. 
When invoking several copies of m5 on the same machine at the same
time, there can be a race for TCP ports for the terminal connections
or remote gdb.  Expose a function to disable those ports, and have the
regression scripts disable them.  There are some SimObjects that have
no other function than to be used with ports (NativeTrace and
EtherTap), so they will panic if the ports are disabled.

54cc0053f0 params: Deprecate old-style constructors; update most SimObject constructors. 
SimObjects not yet updated:
- Process and subclasses
- BaseCPU and subclasses

The SimObject(const std::string &name) constructor was removed.  Subclasses
that still rely on that behavior must call the parent initializer as
  : SimObject(makeParams(name))

way so a cache can handle partial block requests for i/o devices.

abc76f20cb Major changes to how SimObjects are created and initialized. Almost all 
creation and initialization now happens in python.  Parameter objects
are generated and initialized by python.  The .ini file is now solely for
debugging purposes and is not used in construction of the objects in any
way.

7cd6c7ee05 Fix & tweak DPRINTFs for tracediff w/new cache code. 
Note that we should *not* print pointer values in DPRINTFs as
these needlessly clutter tracediff output.
