	The necessary companion conversion of Ruby objects generated by SLICC are converted to M5 SimObjects in the following patch, so this patch alone does not compile. Conversion of Garnet network models is also handled in a separate patch; that code is temporarily disabled from compiling to allow testing of interim code.
2010-01-19	ruby: new atomics implementation	Derek Hower
	This patch changes the way that Ruby handles atomic RMW instructions. This implementation, unlike the prior one, is protocol independent. It works by locking an address from the sequencer immediately after the read portion of an RMW completes. When that address is locked, the coherence controller will only satisfy requests coming from one port (e.g., the mandatory queue) and will ignore all others. After the write portion completed, the line is unlocked. This should also work with multi-line atomics, as long as the blocks are always acquired in the same order.

2009-08-04	slicc: added MOESI_CMP_directory, DMA SequencerMsg, parameterized controllers	Derek Hower
	This changeset contains a lot of different changes that are too mingled to separate. They are: 1. Added MOESI_CMP_directory I made the changes necessary to bring back MOESI_CMP_directory, including adding a DMA controller. I got rid of MOESI_CMP_directory_m and made MOESI_CMP_directory use a memory controller. Added a new configuration for two level protocols in general, and MOESI_CMP_directory in particular. 2. DMA Sequencer uses a generic SequencerMsg I will eventually make the cache Sequencer use this type as well. It doesn't contain an offset field, just a physical address and a length. MI_example has been updated to deal with this. 3. Parameterized Controllers SLICC controllers can now take custom parameters to use for mapping, latencies, etc. Currently, only int parameters are supported.
