2011-04-15trace: reimplement the DTRACE function so it doesn't use a vectorNathan Binkert
At the same time, rename the trace flags to debug flags since they have broader usage than simply tracing. This means that --trace-flags is now --debug-flags and --trace-help is now --debug-help

2011-04-15region: add a utility class for keeping track of regions of some rangeNathan Binkert
This is basically like the range_map stuff in src/base (range already exists in Python). This code is like a set of ranges. I'm using it to keep track of changed lines in source code, but it could be use to keep track of memory ranges and holes in memory regions. It could also be used in memory allocation type stuff. (Though it's not at all optimized.)

2011-04-04ARM: Use CPU local lock before sending load to mem system.Ali Saidi
This change uses the locked_mem.hh header to handle implementing CLREX. It simplifies the current implementation greatly.
2011-04-04ARM: Fix checkpoint restoration into O3 CPU and the way O3 switchCpu works.Ali Saidi
This change fixes a small bug in the arm copyRegs() code where some registers wouldn't be copied if the processor was in a mode other than MODE_USER. Additionally, this change simplifies the way the O3 switchCpu code works by utilizing TheISA::copyRegs() to copy the required context information rather than the adhoc copying that goes on in the CPU model. The current code makes assumptions about the visibility of int and float registers that aren't true for all architectures in FS mode.
2011-04-04ARM: Fix bug in MicroLdrNeon templates for initiateAcc().Ali Saidi
2011-04-04ARM: Cleanup and small fixes to some NEON ops to match the spec.William Wang
Only certain bits of the cpacr can be written, some must be equal. Mult instructions that write the same register should do something sane
2011-04-04ARM: Cleanup implementation of ITSTATE and put important code in PCState.Ali Saidi
Consolidate all code to handle ITSTATE in the PCState object rather than touching a variety of structures/objects.
2011-04-04ARM: Fix m5op parameters bug.Ali Saidi
All the m5op parameters are 64 bits, but we were only sending 32 bits; and the static register indexes were incorrectly specified.

2011-04-04CPU: Remove references to memory copy operationsAli Saidi
2011-04-04O3: Tighten memory order violation checking to 16 bytes.Ali Saidi
The comment in the code suggests that the checking granularity should be 16 bytes, however in reality the shift by 8 is 256 bytes which seems much larger than required.

2011-04-01hammer: fixed dma uniproc errorBrad Beckmann
Fixed an error reguarding DMA for uninprocessor systems. Basically removed an overly agressive optimization that lead to inconsistent state between the cache and the directory.
2011-03-31CacheMemory: add allocateVoid() that is == allocate() but no return value.Lisa Hsu
This function duplicates the functionality of allocate() exactly, except that it does not return a return value. In protocols where you just want to allocate a block but do not want that block to be your implicitly passed cache_entry, use this function. Otherwise, SLICC will complain if you do not consume the pointer returned by allocate(), and if you do a dummy assignment Entry foo := cache.allocate(address), the C++ compiler will complain of an unused variable. This is kind of a hack to get around those issues, but suggestions welcome.
2011-03-31Ruby: Simplify SLICC and Entry/TBE handling.Lisa Hsu
Before this changeset, all local variables of type Entry and TBE were considered to be pointers, but an immediate use of said variables would not be automatically deferenced in SLICC-generated code. Instead, deferences occurred when such variables were passed to functions, and were automatically dereferenced in the bodies of the functions (e.g. the implicitly passed cache_entry). This is a more general way to do it, which leaves in place the assumption that parameters to functions and local variables of type AbstractCacheEntry and TBE are always pointers, but instead of dereferencing to access member variables on a contextual basis, the dereferencing automatically occurs on a type basis at the moment a member is being accessed. So, now, things you can do that you couldn't before include: Entry foo := getCacheEntry(address); cache_entry.DataBlk := foo.DataBlk; or cache_entry.DataBlk := getCacheEntry(address).DataBlk; or even cache_entry.DataBlk := static_cast(Entry, pointer, cache.lookup(address)).DataBlk;
2011-03-31Ruby: Add new object called WireBuffer to mimic a Wire.Lisa Hsu
This is a substitute for MessageBuffers between controllers where you don't want messages to actually go through the Network, because requests/responses can always get reordered wrt to one another (even if you turn off Randomization and turn on Ordered) because you are, after all, going through a network with contention. For systems where you model multiple controllers that are very tightly coupled and do not actually go through a network, it is a pain to have to write a coherence protocol to account for mixed up request/response orderings despite the fact that it's completely unrealistic. This is *not* meant as a substitute for real MessageBuffers when messages do in fact go over a network.
2011-03-31Ruby: have the rubytester pass contextId to Ruby.Lisa Hsu
2011-03-31Ruby: enable multiple sequencers in one controller.Lisa Hsu
2011-03-31Ruby: pass Packet->Req->contextId() to Ruby.Lisa Hsu
It is useful for Ruby to understand from whence request packets came. This has all request packets going into Ruby pass the contextId value, if it exists. This supplants the old libruby proc_id value passed around in all the Messages, so I've also removed the unused unsigned proc_id; member generated by SLICC for all Message types.

2011-03-26mips: cleanup ISA-specific codeKorey Sewell
*** (1): get rid of expandForMT function MIPS is the only ISA that cares about having a piece of ISA state integrate multiple threads so add constants for MIPS and relieve the other ISAs from having to define this. Also, InOrder was the only core that was actively calling this function * * * (2): get rid of corespecific type The CoreSpecific type was used as a proxy to pass in HW specific params to a MIPS CPU, but since MIPS FS hasnt been touched for awhile, it makes sense to not force every other ISA to use CoreSpecific as well use a special reset function to set it. That probably should go in a PowerOn reset fault anyway.

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.
