2014-04-08ruby: slicc: change enqueue statementNilay Vaish
As of now, the enqueue statement can take in any number of 'pairs' as argument. But we only use the pair in which latency is the key. This latency is allowed to be either a fixed integer or a member variable of controller in which the expression appears. This patch drops the use of pairs in an enqueue statement. Instead, an expression is allowed which will be interpreted to be the latency of the enqueue. This expression can anything allowed by slicc including a constant integer or a member variable.

2013-02-10ruby: replaces Time with Cycles in many placesNilay Vaish
The patch started of with replacing Time with Cycles in the Consumer class. But to get ruby to compile, the rest of the changes had to be carried out. Subsequent patches will further this process, till we completely replace Time with Cycles.

2011-06-30Ruby: Add support for functional accessesBrad Beckmann ext:(%2C%20Nilay%20Vaish%20%3Cnilay%40cs.wisc.edu%3E)
This patch rpovides functional access support in Ruby. Currently only the M5Port of RubyPort supports functional accesses. The support for functional through the PioPort will be added as a separate patch.
2011-06-08Ruby: Correctly set access permissions for directory entriesNilay Vaish
The access permissions for the directory entries are not being set correctly. This is because pointers are not used for handling directory entries. function. get and set functions for access permissions have been added to the Controller state machine. The changePermission() function provided by the AbstractEntry and AbstractCacheEntry classes has been exposed to SLICC code once again. The set_permission() functionality has been removed. NOTE: Each protocol will have to define these get and set functions in order to compile successfully.

Forgot to add this to MI_example in my previous patch.
2011-02-23ruby: automate permission settingBrad Beckmann
This patch integrates permissions with cache and memory states, and then automates the setting of permissions within the generated code. No longer does one need to manually set the permissions within the setState funciton. This patch will faciliate easier functional access support by always correctly setting permissions for both cache and memory states. --HG-- rename : src/mem/slicc/ast/EnumDeclAST.py => src/mem/slicc/ast/StateDeclAST.py rename : src/mem/slicc/ast/TypeFieldEnumAST.py => src/mem/slicc/ast/TypeFieldStateAST.py

2009-08-04slicc: added MOESI_CMP_directory, DMA SequencerMsg, parameterized controllersDerek 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.
2009-07-18ruby: fixed dma sequencer bugDerek Hower
The DMASequencer was still using a parameter from the old RubyConfig, causing an offset error when the requested data wasn't block aligned. This changeset also includes a fix to MI_example for a similar bug.
2009-07-06ruby: Import the latest ruby changes from gems.Nathan Binkert
This was done with an automated process, so there could be things that were done in this tree in the past that didn't make it. One known regression is that atomic memory operations do not seem to work properly anymore.
