Brad Beckmann	b6d08e0455	ruby: Fixed RubyPort sendTiming callbacks ... Fixed RubyPort schedSendTiming calls to match ruby frequency.	2010-08-20 11:46:13 -07:00
Brad Beckmann	45f6f31d7a	ruby: fixed token bugs associated with owner token counts ... 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. :)	2010-08-20 11:46:13 -07:00
Brad Beckmann	fb2e0f56ef	ruby: MOESI_CMP_token dma fixes ... This patch fixes various protocol bugs regarding races between dma requests and persistent requests.	2010-08-20 11:46:13 -07:00
Brad Beckmann	6a4f99899b	ruby: Resurrected Ruby's deterministic tests ... Added the request series and invalidate deterministic tests as new cpu models and removed the no longer needed ruby tests --HG-- rename : configs/example/rubytest.py => configs/example/determ_test.py rename : src/mem/ruby/tester/DetermGETXGenerator.cc => src/cpu/directedtest/DirectedGenerator.cc rename : src/mem/ruby/tester/DetermGETXGenerator.hh => src/cpu/directedtest/DirectedGenerator.hh rename : src/mem/ruby/tester/DetermGETXGenerator.cc => src/cpu/directedtest/InvalidateGenerator.cc rename : src/mem/ruby/tester/DetermGETXGenerator.hh => src/cpu/directedtest/InvalidateGenerator.hh rename : src/cpu/rubytest/RubyTester.cc => src/cpu/directedtest/RubyDirectedTester.cc rename : src/cpu/rubytest/RubyTester.hh => src/cpu/directedtest/RubyDirectedTester.hh rename : src/mem/ruby/tester/DetermGETXGenerator.cc => src/cpu/directedtest/SeriesRequestGenerator.cc rename : src/mem/ruby/tester/DetermGETXGenerator.hh => src/cpu/directedtest/SeriesRequestGenerator.hh	2010-08-20 11:46:13 -07:00
Brad Beckmann	984adf198a	ruby: Updated MOESI_hammer L2 latency behavior ... 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.	2010-08-20 11:46:13 -07:00
Brad Beckmann	29c45ccd23	ruby: Reduced ruby latencies ... 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.	2010-08-20 11:46:12 -07:00
Brad Beckmann	8e5c441a54	ruby: fix ruby llsc support to sync sc outcomes ... Added support so that ruby can determine the outcome of store conditional operations and reflect that outcome to M5 physical memory and cpus.	2010-08-20 11:46:12 -07:00
Brad Beckmann	54d76f0ce5	ruby: Fixed L2 cache miss profiling ... Fixed L2 cache miss profiling for the MOESI_CMP_token protocol	2010-08-20 11:46:12 -07:00

Brad Beckmann	4b4e725921	ruby: Reincarnated the responding machine profiling ... 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.	2010-08-20 11:46:12 -07:00
Brad Beckmann	9fb4381ddc	MOESI_CMP_token: Fixed dma persistent lockdown bugs	2010-08-20 11:46:12 -07:00
Brad Beckmann	808701a10c	memtest: Memtester support for DMA ... 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.	2010-08-20 11:46:12 -07:00
Brad Beckmann	64b2205992	ruby: Added ruby_request_type ostream def to libruby.hh	2010-08-20 11:46:12 -07:00
Brad Beckmann	d694cc1384	slicc: Consolidated the protocol stats printing ... Created a separate ProfileDumper that consolidates the generated stats for each controller of a certain type.	2010-08-20 11:46:12 -07:00
Brad Beckmann	09854be558	config: Added the topology description to m5 config.ini	2010-08-20 11:46:11 -07:00

Brad Beckmann	d7d73680c4	MESI_CMP_directory: bug fix for old PUTX requests	2010-08-20 11:41:35 -07:00
Steve Reinhardt	0685ae7a2d	bus: clean up default responder code. ... Clean up some minor things left over from the default responder change in rev 9af6fb59752f. Mostly renaming the 'responder_set' param to 'use_default_range' to actually reflect what it does... old name wasn't that descriptive in the first place, but now it really doesn't make sense at all. Also got rid of the bogus obsolete assignment to 'bus.responder' which used to be a parameter but now is interpreted as an implicit child assignment, and which was giving me problems in the config restructuring to come. (A good argument for not allowing implicit child assignments, IMO, but that's water under the bridge, I'm afraid.) Also moved the Bus constructor to the .cc file since that's where it should have been all along.	2010-08-17 05:06:21 -07:00
Timothy M. Jones	28a5ea3f99	Port: Only indicate that a SimpleTimingPort is drained if its send event is ... not scheduled, as well as the transmit list being empty.	2010-07-22 18:54:37 +01:00
Steve Reinhardt	897247d63b	cache: fix bug in SC upgrade handling ... This bug was introduced with the recent rework of SC failure handling in cset f97b62be544f.	2010-07-08 17:56:13 -07:00
Brad Beckmann	a03c1cd6e0	garnet: Added topology print function to Garnet printStats	2010-07-08 16:18:20 -07:00

Tushar Krishna	66f0d26059	style: updated garnet to match M5 coding style	2010-06-22 15:36:07 -07:00
Steve Reinhardt	de2321de81	cache: fix longstanding prefetcher bug ... Thanks to Joe Gross for pointing this out (again?). Apologies to anyone who pointed it out earlier and we didn't listen.	2010-06-22 21:29:43 -07:00
Steve Reinhardt	f24ae2ec2a	cache: fail store conditionals when upgrade loses race ... Requires new "SCUpgradeReq" message that marks upgrades for store conditionals, so downstream caches can fail these when they run into invalidations. See http://www.m5sim.org/flyspray/task/197	2010-06-16 15:25:57 -07:00
Steve Reinhardt	57f2b7db11	cache: fix dirty bit setting ... Only set the dirty bit when we actually write to a block (not if we thought we might but didn't, as in a failed SC or CAS). This requires makeing sure the dirty bit stays set when we get an exclusive (writable) copy in a cache-to-cache transfer from another owner, which n turn requires copying the mem-inhibit flag from timing-mode requests to their associated responses.	2010-06-16 15:25:57 -07:00
Nathan Binkert	86a93fe7b9	stats: only consider a formula initialized if there is a formula	2010-06-15 01:18:36 -07:00
Nathan Binkert	dd133c7b24	ruby: get rid of PrioHeap and use STL ... One big difference is that PrioHeap puts the smallest element at the top of the heap, whereas stl puts the largest element on top, so I changed all comparisons so they did the right thing. Some usage of PrioHeap was simply changed to a std::vector, using sort at the right time, other usage had me just use the various heap functions in the stl.	2010-06-10 23:17:07 -07:00
Nathan Binkert	3df84fd8a0	ruby: get rid of the Map class	2010-06-10 23:17:07 -07:00
Nathan Binkert	006818aeea	ruby: get rid of Vector and use STL ... add a couple of helper functions to base for deleteing all pointers in a container and outputting containers to a stream	2010-06-10 23:17:07 -07:00
Nathan Binkert	bc87fa30d7	ruby: get rid of RefCnt and Allocator stuff use base/refcnt.hh ... This was somewhat tricky because the RefCnt API was somewhat odd. The biggest confusion was that the the RefCnt object's constructor that took a TYPE& cloned the object. I created an explicit virtual clone() function for things that took advantage of this version of the constructor. I was conservative and used clone() when I was in doubt of whether or not it was necessary. I still think that there are probably too many instances of clone(), but hopefully not too many. I converted several instances of const MsgPtr & to a simple MsgPtr. If the function wants to avoid the overhead of creating another reference, then it should just use a regular pointer instead of a ref counting ptr. There were a couple of instances where refcounted objects were created on the stack. This seems pretty dangerous since if you ever accidentally make a reference to that object with a ref counting pointer, bad things are bound to happen.	2010-06-10 23:17:06 -07:00
Steve Reinhardt	4977d8b58f	scons: make RUBY a regular (non-global) sticky var ... and force it to True for builds that imply Ruby protocols (else unexpected things happen when testing these builds with RUBY=False).	2010-06-07 12:19:59 -04:00
Nathan Binkert	c1aabe8172	style: clean up ruby's Set class ... Further cleanup should probably be done to make this class be non-Ruby specific and put it in src/base. There are probably several cases where this class is used, std::bitset could be used instead.	2010-06-01 11:38:56 -07:00
Nathan Binkert	e99828b06a	tick: rename Clock namespace to SimClock	2010-04-15 16:24:12 -07:00

Nathan Binkert	f1c3f3044b	ruby: get "using namespace" out of headers ... In addition to obvious changes, this required a slight change to the slicc grammar to allow types with :: in them. Otherwise slicc barfs on std::string which we need for the headers that slicc generates.	2010-04-02 11:20:32 -07:00

Brad Beckmann	f9408f984f	ruby: Changed the default set size to 1 ... Previously, the set size was set to 4. This was mostly do to the fact that a crazy graduate student use to create networks with 256 l2 cache banks. Now it is far more likely that users will create systems with less than 64 of any particular controller type. Therefore Ruby should be optimized for a set size of 1.	2010-03-21 21:22:21 -07:00

Lisa Hsu	7f3cd9a9fd	cache stats: account for writebacks and/or device occupancy in the cache. ... Plus, a minor bugfix that neglects to update blk->contextSrc in certain cases on a cache insert.	2010-02-24 13:46:55 -08:00
Lisa Hsu	1d3228481f	cache: Make caches sharing aware and add occupancy stats. ... On the config end, if a shared L2 is created for the system, it is parameterized to have n sharers as defined by option.num_cpus. In addition to making the cache sharing aware so that discriminating tag policies can make use of context_ids to make decisions, I added an occupancy AverageStat and an occ % stat to each cache so that you could know which contexts are occupying how much cache on average, both in terms of blocks and percentage. Note that since devices have context_id -1, having an array of occ stats that correspond to each context_id will break here, so in FS mode I add an extra bucket for device blocks. This bucket is explicitly not added in SE mode in order to not only avoid ugliness in the stats.txt file, but to avoid broken stats (some formulas break when a bucket is 0).	2010-02-23 09:34:22 -08:00

Brad Beckmann	ab2f864af2	m5: Regression Tester Update ... This patch includes the necessary regression updates to test the new ruby configuration system. The patch includes support for multiple ruby protocols and adds the ruby random tester. The patch removes atomic mode test for ruby since ruby does not support atomic mode acceses. These tests can be added back in when ruby supports atomic mode for real. --HG-- rename : tests/quick/50.memtest/test.py => tests/quick/60.rubytest/test.py	2010-01-29 20:29:40 -08:00

Cleaned up the ruby profilers by moving the memory controller profiling code out of the main profiler object and into a separate object similar to the current CacheProfiler. Both the CacheProfiler and MemCntrlProfiler are specific to a particular Ruby object, CacheMemory and MemoryControl respectively. Therefore, these profilers should not be SimObjects and created by the python configuration system, but instead private objects. This simplifies the creation of these profilers.	2010-01-29 20:29:22 -08:00

Brad Beckmann	0f6535dba1	ruby: Convered ruby tracing support usage of sequencer ... Modified ruby's tracing support to no longer rely on the RubySystem map to convert a sequencer string name to a sequencer pointer. As a temporary solution, the code uses the sim_object find function. Eventually, we should develop a better fix.	2010-01-29 20:29:20 -08:00
Brad Beckmann	2c9ca672df	ruby: Memory Controller Profiler with new config system ... This patch includes a rather substantial change to the memory controller profiler in order to work with the new configuration system. Most noteably, the mem_cntrl_profiler no longer uses a string map, but instead a vector. Eventually this support should be removed from the main profiler and go into a separate object. Each memory controller should have a pointer to that new mem_cntrl profile object.	2010-01-29 20:29:20 -08:00

Note this aggregation stuff has only been tested for Alpha and nothing else, though it should take a very minimal amount of work to get it to work with another ISA.	2010-01-19 22:03:44 -08:00
Derek Hower	07ea0891f1	ruby: new atomics implementation ... 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.	2010-01-19 17:11:36 -06:00

Derek Hower	33b28fde7a	slicc: added MOESI_CMP_directory, DMA SequencerMsg, parameterized controllers ... 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.	2009-08-04 12:52:52 -05:00

Nathan Binkert	8291d9db0a	eventq: Major API change for the Event and EventQueue structures. ... Since the early days of M5, an event needed to know which event queue it was on, and that data was required at the time of construction of the event object. In the future parallelized M5, this sort of requirement does not work well since the proper event queue will not always be known at the time of construction of an event. Now, events are created, and the EventQueue itself has the schedule function, e.g. eventq->schedule(event, when). To simplify the syntax, I created a class called EventManager which holds a pointer to an EventQueue and provides the schedule interface that is a proxy for the EventQueue. The intent is that objects that frequently schedule events can be derived from EventManager and then they have the schedule interface. SimObject and Port are examples of objects that will become EventManagers. The end result is that any SimObject can just call schedule(event, when) and it will just call that SimObject's eventq->schedule function. Of course, some objects may have more than one EventQueue, so this interface might not be perfect for those, but they should be relatively few.	2008-10-09 04:58:23 -07:00

I haven't deleted the functionality in this patch that will come later, but one question is how to enforce encourage objects that call getVirtPort() to not cache the virtual port since if the CPU changes out from under them it will be worse than useless.
