2011-03-22Ruby: Remove CacheMsg class from SLICCNilay Vaish
The goal of the patch is to do away with the CacheMsg class currently in use in coherence protocols. In place of CacheMsg, the RubyRequest class will used. This class is already present in slicc_interface/RubyRequest.hh. In fact, objects of class CacheMsg are generated by copying values from a RubyRequest object.

2011-03-21This patch adds the network tester for simple and garnet networks.Tushar Krishna
The tester code is in testers/networktest. The tester can be invoked by configs/example/ruby_network_test.py. A dummy coherence protocol called Network_test is also addded for network-only simulations and testing. The protocol takes in messages from the tester and just pushes them into the network in the appropriate vnet, without storing any state.
2011-03-20SLICC: Remove WakeUp* import calls from ast/__init__.pyNilay Vaish
I had recently committed a patch that removed the WakeUp*.py files from the slicc/ast directory. I had forgotten to remove the import calls for these files from slicc/ast/__init__.py. This resulted in error while running regressions on zizzer. This patch does the needful.

2011-03-18SLICC: Remove external_type for structuresNilay Vaish
In SLICC, in order to define a type a data type for which it should not generate any code, the keyword external_type is used. For those data types for which code should be generated, the keyword structure is used. This patch eliminates the use of keyword external_type for defining structures. structure key word can now have an optional attribute external, which would be used for figuring out whether or not to generate the code for this structure. Also, now structures can have functions as well data members in them.
2011-03-18SLICC: Remove the keyword wake_up_dependentsNilay Vaish
In order to add stall and wait facility for protocols, a keyword wake_up_dependents was introduced. This patch removes the keyword, instead this functionality is now implemented as function call.
2011-03-18SLICC: Remove the keyword wake_up_all_dependentsNilay Vaish
In order to add stall and wait facility for protocols, a keyword wake_up_all_dependents was introduced. This patch removes the keyword, instead this functionality is now implemented as function call.

non-cache. This change fixes the problem for all the cases we actively use. If you want to try more creative I/O device attachments (E.g. sharing an L2), this won't work. You would need another level of caching between the I/O device and the cache (which you actually need anyway with our current code to make sure writes propagate). This is required so that you can mark the cache in between as top level and it won't try to send ownership of a block to the I/O device. Asserts have been added that should catch any issues.

2011-03-11Ruby: Get rid of the dead ruby tester.Gabe Black
None of the code in the ruby tester directory is compiled or referred to outside of that directory. This change eliminates it. If it's needed in the future, it can be revived from the history. In the mean time, this removes clutter and the only use of the GEMS_ROOT scons variable.

There may not be a formally correct spelling for the past tense of mmap, but mmapped is the spelling Google doesn't try to autocorrect. This makes sense because it mirrors the past tense of map->mapped and not the past tense of cape->caped. --HG-- rename : src/arch/alpha/mmaped_ipr.hh => src/arch/alpha/mmapped_ipr.hh rename : src/arch/arm/mmaped_ipr.hh => src/arch/arm/mmapped_ipr.hh rename : src/arch/mips/mmaped_ipr.hh => src/arch/mips/mmapped_ipr.hh rename : src/arch/power/mmaped_ipr.hh => src/arch/power/mmapped_ipr.hh rename : src/arch/sparc/mmaped_ipr.hh => src/arch/sparc/mmapped_ipr.hh rename : src/arch/x86/mmaped_ipr.hh => src/arch/x86/mmapped_ipr.hh
2011-03-01Ruby: Fix DPRINTF bugs in PerfectSwitch and MessageBufferNilay Vaish
At a couple of places in PerfectSwitch.cc and MessageBuffer.cc, DPRINTF() has not been provided with correct number of arguments. The patch fixes these bugs.

2011-02-25Ruby: Remove store bufferNilay Vaish
This patch removes the store buffer from Ruby. It is not in use currently. Since libruby is being and store buffer makes calls to libruby, it is not possible to maintain it until substantial changes are made.
2011-02-25Ruby: Remove librubyNilay Vaish
This patch removes libruby_internal.hh, libruby.hh and libruby.cc. It moves the contents to libruby.hh to RubyRequest.hh and RubyRequest.cc files.
2011-02-25Ruby: Make Address.hh independent of RubySystemNilay Vaish
This patch changes Address.hh so that it is not dependent on RubySystem. This dependence seems unecessary. All those functions that depend on RubySystem have been moved to Address.cc file.
2011-02-25Ruby: Make DataBlock.hh independent of RubySystemNilay Vaish
This patch changes DataBlock.hh so that it is not dependent on RubySystem. This dependence seems unecessary. All those functions that depende on RubySystem have been moved to DataBlock.cc file.
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

2011-02-23ruby: extend dprintfs for RubyGenerated TraceFlagKorey Sewell
"executing" isnt a very descriptive debug message and in going through the output you get multiple messages that say "executing" but nothing to help you parse through the code/execution. So instead, at least print out the name of the action that is taking place in these functions.
2011-02-23ruby: cleaning up RubyQueue and RubyNetwork dprintfsKorey Sewell
Overall, continue to progress Ruby debug messages to more of the normal M5 debug message style - add a name() to the Ruby Throttle & PerfectSwitch objects so that the debug output isn't littered w/"global:" everywhere. - clean up messages that print over multiple lines when possible - clean up duplicate prints in the message buffer

2011-02-19Ruby: Machine Type missing in MOESI CMP directory protocolNilay Vaish
In certain actions of the L1 cache controller, while creating an outgoing message, the machine type was not being set. This results in a segmentation fault when trace is collected. Joseph Pusudesris provided his patch for fixing this issue.
2011-02-19Ruby: clean MOESI CMP directory protocolNilay Vaish
The L1 cache controller file contains references to foo and goo queues, which are not in use at all. These have been removed.
2011-02-14Ruby: Improve Change PerfectSwitch's wakeup functionNilay Vaish
Currently the wakeup function for the PerfectSwitch contains three loops - loop on number of virtual networks loop on number of incoming links loop till all messages for this (link, network) have been routed With an 8 processor mesh network and Hammer protocol, about 11-12% of the was observed to have been spent in this function, which is the highest amongst all the functions. It was found that the innermost loop is executed about 45 times per invocation of the wakeup function, when each invocation of the wakeup function processes just about one message. The patch tries to do away with the redundant executions of the innermost loop. Counters have been added for each virtual network that record the number of messages that need to be routed for that virtual network. The inner loops are only executed when the number of messages for that particular virtual network > 0. This does away with almost 80% of the executions of the innermost loop. The function now consumes about 5-6% of the total execution time.
2011-02-12Ruby: Reorder Cache Lookup in Protocol FilesNilay Vaish
The patch changes the order in which L1 dcache and icache are looked up when a request comes in. Earlier, if a request came in for instruction fetch, the dcache was looked up before the icache, to correctly handle self-modifying code. But, in the common case, dcache is going to report a miss and the subsequent icache lookup is going to report a hit. Given the invariant - caches under the same controller keep track of disjoint sets of cache blocks, we can move the icache lookup before the dcache lookup. In case of a hit in the icache, using our invariant, we know that the dcache would have reported a miss. In case of a miss in the icache, we know that icache would have missed even if the dcache was looked up before looking up the icache. Effectively, we are doing the same thing as before, though in the common case, we expect reduction in the number of lookups. This was empirically confirmed for MOESI hammer. The ratio lookups to access requests is now about 1.1 to 1.

2011-02-08MESI CMP: Unset TBE pointer in L2 cache controllerNilay Vaish
The TBE pointer in the MESI CMP implementation was not being set to NULL when the TBE is deallocated. This resulted in segmentation fault on testing the protocol when the ProtocolTrace was switched on.
