2010-12-23PerfectCacheMemory: Add return statements to two functions.Nilay Vaish
Two functions in src/mem/ruby/system/PerfectCacheMemory.hh, tryCacheAccess() and cacheProbe(), end with calls to panic(). Both of these functions have return type other than void. Any file that includes this header file fails to compile because of the missing return statement. This patch adds dummy values so as to avoid the compiler warnings.
2010-12-22This patch removes the WARN_* and ERROR_* from src/mem/ruby/common/Debug.hh ↵Nilay Vaish
file. These statements have been replaced with warn(), panic() and fatal() defined in src/base/misc.hh
2010-12-08ruby: remove Ruby asserts for m5.fastBrad Beckmann
This diff is for changing the way ASSERT is handled in Ruby. m5.fast compiles out the assert statements by using the macro NDEBUG. Ruby uses the macro RUBY_NO_ASSERT to do so. This macro has been removed and NDEBUG has been put in its place.
2010-12-01ruby: Converted old ruby debug calls to M5 debug callsNilay Vaish
This patch developed by Nilay Vaish converts all the old GEMS-style ruby debug calls to the appropriate M5 debug calls.
2010-11-19SE: Fix simulating more than 4GB of RAM in SE modeAli Saidi
This change removes some dead code in PhysicalMemory, uses a 64 bit type for the page pointer in System (instead of 32 bit) and cleans up some style.
2010-11-19SCons: Support building without an ISAAli Saidi
2010-11-08ARM: Add checkpointing supportAli Saidi
2010-11-08Mem: Finish half-baked support for mmaping file in physmem.Ali Saidi
Physmem has a parameter to be able to mem map a file, however it isn't actually used. This changeset utilizes the parameter so a file can be mmapped.
2010-10-18cache: minor SC assertion fixSteve Reinhardt
Thanks to Joe Gross for finding/testing this.
2010-10-16Mem: Reclaim some request flags used by MIPS for alignment checking.Gabe Black
These flags were being used to identify what alignment a request needed, but the same information is available using the request size. This change also eliminates the isMisaligned function. If more complicated alignment checks are needed, they can be signaled using the ASI_BITS space in the flags vector like is currently done with ARM.
2010-10-13Mem: Change the CLREX flag to CLEAR_LL.Gabe Black
CLREX is the name of an ARM instruction, not a name for this generic flag.
2010-09-30CPU/Cache: Fix some errors exposed by valgrindAli Saidi
2010-09-21cache: improve coherence handling of writebacksSteve Reinhardt
If we write back an exclusive copy, we now mark it as such, so the cache receiving the writeback can mark its copy as exclusive. This avoids some unnecessary upgrade requests when a cache later tries to re-acquire exclusive access to the block.
2010-09-13Faults: Pass the StaticInst involved, if any, to a Fault's invoke method.Gabe Black
Also move the "Fault" reference counted pointer type into a separate file, sim/fault.hh. It would be better to name this less similarly to sim/faults.hh to reduce confusion, but fault.hh matches the name of the type. We could change Fault to FaultPtr to match other pointer types, and then changing the name of the file would make more sense.
2010-09-10style: fix sorting of includes and whitespace in some filesNathan Binkert
2010-09-09code_formatter: make it easier to insert whitespaceNathan Binkert
a newline by just doing "code()". indent() and dedent() now take a "count" parameter to indent/dedent multiple levels.
2010-09-09cache: fail SC when invalidated while waiting for busSteve Reinhardt
Corrects an oversight in cset f97b62be544f. The fix there only failed queued SCUpgradeReq packets that encountered an invalidation, which meant that the upgrade had to reach the L2 cache. To handle pending requests in the L1 we must similarly fail StoreCondReq packets too.
2010-09-09mem: fix functional accesses to deal with coherence changeSteve Reinhardt
We can't just obliviously return the first valid cache block we find any more... see comments for details.
2010-09-09cache: coherence protocol enhancements & bug fixesSteve Reinhardt
Allow lower-level caches (e.g., L2 or L3) to pass exclusive copies to higher levels (e.g., L1). This eliminates a lot of unnecessary upgrade transactions on read-write sequences to non-shared data. Also some cleanup of MSHR coherence handling and multiple bug fixes.

Added an optimization that merges multiple pending GETS requests into a single request to the owner node.
2010-08-20ruby: Stall and wait input messages instead of recyclingBrad Beckmann
This patch allows messages to be stalled in their input buffers and wait until a corresponding address changes state. In order to make this work, all in_ports must be ranked in order of dependence and those in_ports that may unblock an address, must wake up the stalled messages. Alot of this complexity is handled in slicc and the specification files simply annotate the in_ports. --HG-- rename : src/mem/slicc/ast/CheckAllocateStatementAST.py => src/mem/slicc/ast/StallAndWaitStatementAST.py rename : src/mem/slicc/ast/CheckAllocateStatementAST.py => src/mem/slicc/ast/WakeUpDependentsStatementAST.py
2010-08-20ruby: Recycle latency fix for hammerBrad Beckmann
Patch allows each individual message buffer to have different recycle latencies and allows the overall recycle latency to be specified at the cmd line. The patch also adds profiling info to make sure no one processor's requests are recycled too much.
2010-08-20MOESI_hammer: break down miss latency stalled cyclesBrad Beckmann
This patch tracks the number of cycles a transaction is delayed at different points of the request-forward-response loop.
2010-08-20ruby: added probe filter support to hammerBrad Beckmann
2010-08-20ruby: fixed DirectoryMemory's numa_high_bit configurationBrad Beckmann
This fix includes the off-by-one bit selection bug for numa mapping.
2010-08-20ruby: Reset ruby stats in RubySystem unserializeBrad Beckmann
The main purpose for clearing stats in the unserialize process is so that the profiler can correctly set its start time to the unserialized value of curTick.
2010-08-20ruby: Disable migratory sharing for token and hammerBrad Beckmann
This patch allows one to disable migratory sharing for those cache blocks that are accessed by atomic requests. While the implementations are different between the token and hammer protocols, the motivation is the same. For Alpha, LLSC semantics expect that normal loads do not unlock cache blocks that have been locked by LL accesses. Therefore, locked blocks should not transfer write permissions when responding to these load requests. Instead, only they only transfer read permissions so that the subsequent SC access can possibly succeed.

Fixed RubyPort schedSendTiming calls to match ruby frequency.
2010-08-20ruby: fixed token bugs associated with owner token countsBrad Beckmann
This patch fixes several bugs related to previous inconsistent assumptions on how many tokens the Owner had. Mike Marty should have fixes these bugs years ago. :)

2010-08-20ruby: Updated MOESI_hammer L2 latency behaviorBrad Beckmann
Previously, the MOESI_hammer protocol calculated the same latency for L1 and L2 hits. This was because the protocol was written using the old ruby assumption that L1 hits used the sequencer fast path. Since ruby no longer uses the fast-path, the protocol delays L2 hits by placing them on the trigger queue.
2010-08-20ruby: Reduced ruby latenciesBrad Beckmann
The previous slower ruby latencies created a mismatch between the faster M5 cpu models and the much slower ruby memory system. Specifically smp interrupts were much slower and infrequent, as well as cpus moving in and out of spin locks. The result was many cpus were idle for large periods of time. These changes fix the latency mismatch.
2010-08-20ruby: fix ruby llsc support to sync sc outcomesBrad Beckmann
Added support so that ruby can determine the outcome of store conditional operations and reflect that outcome to M5 physical memory and cpus.

2010-08-20ruby: Reincarnated the responding machine profilingBrad Beckmann
This patch adds back to ruby the capability to understand the response time for messages that hit in different levels of the cache heirarchy. Specifically add support for the MI_example, MOESI_hammer, and MOESI_CMP_token protocols.

2010-08-20memtest: Memtester support for DMABrad Beckmann
This patch adds DMA testing to the Memtester and is inherits many changes from Polina's old tester_dma_extension patch. Since Ruby does not work in atomic mode, the atomic mode options are removed.
