2013-05-30	base: Avoid size limitation on protobuf coded streams	Andreas Hansson
	This patch changes how the streams are created to avoid the size limitation on the coded streams. As we only read/write a single message at a time, there is never any message larger than a few bytes. However, the coded stream eventually complains that its internal counter reaches 64+ MByte if the total file size exceeds this value. Based on suggestions in the protobuf discussion forums, the coded stream is now created for every message that is read/written. The result is that the internal byte count never goes about tens of bytes, and we can read/write any size file that the underlying file I/O can handle.
2013-03-26	mem: Add a generic id field to the packet trace	Andreas Hansson
	This patch adds an optional generic 64-bit identifier field to the packet trace. This can be used to store the sequential number of the instruction that gave rise to the packet, thread id, master id, "sub"-master within a larger module etc. As the field is optional it has a marginal cost if not used.
2013-03-26	mem: Add optional request flags to the packet trace	Andreas Hansson
	This patch adds an optional flags field to the packet trace to encode the request flags that contain information about whether the request is (un)cacheable, instruction fetch, preftech etc.
2013-01-14	scons: Address clang 3.2 compilation error	Andreas Hansson
	This patch fixes a compilation error encountered using clang 3.2 on OSX.
2013-01-07	base: Add wrapped protobuf input stream	Andreas Hansson
	This patch adds support for inputting protobuf messages through a ProtoInputStream which hides the internal streams used by the library. The stream is created based on the name of an input file and optionally includes decompression using gzip. The input stream will start by getting a magic number from the file, and also verify that it matches with the expected value. Once opened, messages can be read incrementally from the stream, returning true/false until an error occurs or the end of the file is reached.
2013-01-07	mem: Add tracing support in the communication monitor	Andreas Hansson
	This patch adds packet tracing to the communication monitor using a protobuf as the mechanism for creating the trace. If no file is specified, then the tracing is disabled. If a file is specified, then for every packet that is successfully sent, a protobuf message is serialized to the file.
2013-01-07	base: Add wrapped protobuf output streams	Andreas Hansson
	This patch adds support for outputting protobuf messages through a ProtoOutputStream which hides the internal streams used by the library. The stream is created based on the name of an output file and optionally includes compression using gzip. The output stream will start by putting a magic number in the file, and then for every message that is serialized prepend the size such that the stream can be written and read incrementally. At this point this merely serves as a proof of concept.
