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
Lisa Hsu	be4cf50c5a	stats: this makes some fixes to AverageStat and AverageVector. ... Also, make Formulas work on AverageVector. First, Stat::Average (and thus Stats::AverageVector) was broken when coming out of a checkpoint and on resets, this fixes that. Formulas also didn't work with AverageVector, but added support for that.	2010-02-23 09:33:18 -08:00
Lisa Hsu	2ad386f104	cache: pull CacheSet out of LRU so that other tags can use associative sets.	2010-02-23 09:33:09 -08:00
Timothy M. Jones	a5feaa6a69	BaseDynInst: Preserve the faults returned from read and write. ... When implementing timing address translations instead of atomic, I forgot to preserve the faults that are returned from the read and write calls. This patch reinstates them.	2010-02-20 20:11:58 +00:00
Timothy M. Jones	29e8bcead5	O3PCU: Split loads and stores that cross cache line boundaries. ... When each load or store is sent to the LSQ, we check whether it will cross a cache line boundary and, if so, split it in two. This creates two TLB translations and two memory requests. Care has to be taken if the first packet of a split load is sent but the second blocks the cache. Similarly, for a store, if the first packet cannot be sent, we must store the second one somewhere to retry later. This modifies the LSQSenderState class to record both packets in a split load or store. Finally, a new const variable, HasUnalignedMemAcc, is added to each ISA to indicate whether unaligned memory accesses are allowed. This is used throughout the changed code so that compiler can optimise away code dealing with split requests for ISAs that don't need them.	2010-02-12 19:53:20 +00:00
Timothy M. Jones	7fe9f92cfc	BaseDynInst: Make the TLB translation timing instead of atomic. ... This initiates a timing translation and passes the read or write on to the processor before waiting for it to finish. Once the translation is finished, the instruction's state is updated via the 'finish' function. A new DataTranslation class is created to handle this. The idea is taken from the implementation of timing translations in TimingSimpleCPU by Gabe Black. This patch also separates out the timing translations from this CPU and uses the new DataTranslation class.	2010-02-12 19:53:19 +00:00

Korey Sewell	82c5a754e6	inorder: recvRetry bug fix ... - on certain retry requests you can get an assertion failure - fix by allowing the request to literally "Retry" itself if it wasnt successful before, and then block any requests through cache port while waiting for the cache to be made available for access	2010-01-31 18:29:18 -05:00

Korey Sewell	4d749472e3	inorder: enforce stage bandwidth ... each stage keeps track of insts_processed on a per_thread basis but we should be keeping that on a total basis inorder to enforce stage width limits	2010-01-31 18:28:31 -05:00
Korey Sewell	b4e0ef7837	inorder: set thread status' ... set Active/Suspended/Halted status for threads. useful for system when determining if/when to exit simulation	2010-01-31 18:28:12 -05:00
Korey Sewell	5e0b8337ed	inorder: add/remove halt/deallocate context respectively ... Halt is called from the exit() system call while deallocate is unused. So to clear up things, just use halt and remove deallocate.	2010-01-31 18:28:05 -05:00
Korey Sewell	069b38c0d5	inorder: track last branch committed ... when threads are switching in/out the CPU, we need to keep track of special cases like branches. Add appropriate variables in ThreadState t track this and then use these variables when updating pc after context switch	2010-01-31 18:27:58 -05:00
Korey Sewell	aacc5cb205	inorder: add updatePC event to resPool ... this will be used for when a thread comes back from a cache miss, it needs to update the PCs because the inst might of been a branch or delayslot in which the next PC isnt always a straight addition	2010-01-31 18:27:49 -05:00
Korey Sewell	90d3b45a56	inorder: ready thread wakeup ... allow a thread to wakeup and be activated after it has been in suspended state and another thread is switched out. Need to give pipeline stages a "activateThread" function so that can get to their suspended instruction when the time is right.	2010-01-31 18:27:38 -05:00
Korey Sewell	3eb04b4ad7	inorder: add threadmodel flag ... this prints out messages relative to what threading model is being used (smt, switch-on-miss, single, etc.)	2010-01-31 18:27:25 -05:00
Korey Sewell	611a8642c2	inorder: mem. mgmt. update ... update address List and address Map to take into account multiple threads	2010-01-31 18:27:12 -05:00
Korey Sewell	4dbc2f1718	inorder: suspend in respool ... give resources their own specific activity to do for a "suspend" event instead of defaulting to deactivating the thread for a suspend thread event. This really matters for the fetch sequence unit which wants to remove the thread from fetching while other units want to ignore a thread suspension. If you deactivate a thread in a resource then you may lose some of the allotted bandwidth that the thread is taking up...	2010-01-31 18:27:02 -05:00
Korey Sewell	4ea296e296	inorder: fetch thread bug ... dont check total # of threads but instead all active threads	2010-01-31 18:26:54 -05:00

Korey Sewell	e1fcc64980	inorder: activate thread on cache miss ... -Support ability to activate next ready thread after a cache miss through the activateNextReadyContext/Thread() functions -To support this a "readyList" of thread ids is added -After a cache miss, thread will suspend and then call activitynextreadythread	2010-01-31 18:26:32 -05:00
Korey Sewell	4a945aab19	inorder: add event priority offset ... allow for events to schedule themselves later if desired. this is important because of cases like where you need to activate a thread only after the previous thread has been deactivated. The ordering there has to be enforced	2010-01-31 18:26:26 -05:00
Korey Sewell	eac5eac67a	inorder: squash on memory stall ... add code to recognize memory stalls in resources and the pipeline as well as squash a thread if there is a stall and we are in the switch on cache miss model	2010-01-31 18:26:13 -05:00
Korey Sewell	d8e0935af2	inorder: add insts to cpu event ... some events are going to need instruction data when they process, so just include the instruction in the event construction	2010-01-31 18:26:03 -05:00
Korey Sewell	e8312ab6f7	inorder: switch out buffer ... add buffer for instructions to switch out to in a pipeline stage can't squash the instruction and remove the pipeline so we kind of need to 'suspend' an instruction at the stage while the memory stall resolves for the switch on cache miss model	2010-01-31 18:25:48 -05:00
Korey Sewell	a892af7b26	inorder: dont allow early loads ... - loads were happening on same cycle as the address was generated which is slightly unrealistic. Instead, force address generation to be on separate cycle from load initiation - also, mark the stages in a more traditional way (F-D-X-M-W)	2010-01-31 18:25:27 -05:00

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

Brad Beckmann	f88faa6c11	ruby: cleaned up ruby profilers ... 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

Lisa Hsu	d6da172517	util: do checkpoint aggregation more cleanly, fix last changeset. ... 1) Move alpha-specific code out of page_table.cc:serialize(). 2) Begin serializing M5_pid and unserializing it, but adding an function to do optional paramIn so that old checkpoints don't need to be fixed up. 3) Fix up alpha startup code so that the unserialized M5_pid value is properly written to DTB_IPR_ASN. 4) Fix the memory unserialize that I forgot somehow in the last changeset. 5) Add in an agg_se.py to handle aggregated checkpoints. --bench foo-bar plus positional arguments foo bar are the only changes in usage from se.py. 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

Gabe Black	d3ed32b989	MIPS: Create an artificial control register to hold the thread pointer. ... In Linux, the set_thread_area system call stores the address of the thread local storage area into a field of the current thread_info structure. Later, to access that value, the program uses the rdhwr instruction to read a "hardware register" with index 29. The 64 bit MIPS manual, volume II, says that index 29 is reserved for a future ABI extension and should cause a "Reserved Instruction Exception". In Linux (and potentially other ISAs) that exception is trapped and emulated to return the value stored by set_thread_area as if that were actually stored by a physical register. The tp_value address (as named in the Linux kernel) is ironically stored as a control register so that it goes with a particular ThreadContext. Syscall emulation will use that to emulate storing to the OS's thread info structure, and rdhwr will emulate faulting and returning that value from software by returning the value itself, as if it was in hardware. In other words, we fake faking the register in SE mode. In an FS mode implementation it should work as specified in the manual.	2009-12-31 15:30:50 -05:00
Gabe Black	cc07dcf026	MIPS: Extract CPU pointer from the thread context in scheduleCP0 setMiscReg. ... The MIPS ISA object expects to be constructed with a CPU pointer it uses to look at other thread contexts and allow them to be manipulated with control registers. Unfortunately, that differs from all the other ISA classes and would complicate their implementation. This change makes the event constructor use a CPU pointer pulled out of the thread context passed to setMiscReg instead.	2009-12-31 15:30:50 -05:00

Gabe Black	4779020e13	ARM: Fix the integer register indexes. ... The PC indexes in the various register sets was defined in the section for unaliased registers which was throwing off the indexing. This moves those where they belong. Also, to make detecting accesses to the PC easier and because it's in the same place in all modes, the intRegForceUser function now passes it through as index 15.	2009-11-10 20:19:55 -08:00
Vince Weaver	53e27c0277	X86: Fix bugs in movd implementation. ... Unfortunately my implementation of the movd instruction had two bugs. In one case, when moving a 32-bit value into an xmm register, the lower half of the xmm register was not zero extended. The other case is that xmm was used instead of xmmlm as the source for a register move. My test case didn't notice this at first as it moved xmm0 to eax, which both have the same register number.	2009-11-10 11:29:30 -05:00
Vince Weaver	e81cc233a6	X86: Remove double-cast in Cvtf2i micro-op ...

Vince Weaver	a1042db290	X86: Enable x86_64 vsyscall support ... 64-bit vsyscall is different than 32-bit. There are only two syscalls, time and gettimeofday. On a real system, there is complicated code that implements these without entering the kernel. That would be complicated to implement in m5. Instead we just place code that calls the regular syscalls (this is how tools such as valgrind handle this case). This is needed for the perlbmk spec2k benchmark.	2009-11-04 00:47:12 -05:00

Vince Weaver	5873ec2238	X86: Implement movd_Vo_Edp on X86 ... This patch implements the movd_Vo_Edp series of instructions. It addresses various concerns by Gabe Black about which file the instruction belonged in, as well as supporting REX prefixed instructions properly. This instruction is needed for some of the spec2k benchmarks, most notably bzip2.	2009-10-30 15:52:33 -04:00
Vince Weaver	b2067840a6	X86: Implement the X86 sse2 haddpd instruction ... This patch implements the haddpd instruction.

Vince Weaver	cf269025f9	X86: Hookup truncate/ftruncate syscalls on X86 ... This patch hooks up the truncate, ftruncate, truncate64 and ftruncate64 system calls on 32-bit and 64-bit X86. These have been tested on both architectures. ftruncate/ftruncate64 is needed for the f90 spec2k benchmarks.	2009-10-30 12:51:13 -04:00
Vince Weaver	9ad3acab5e	SysCalls: Implement truncate64 system call ... This uses the new stack-based argument infrastructure. Tested on x86 and x86_64.	2009-10-30 12:31:55 -04:00

Gabe Black	3f722b991f	Syscalls: Make system calls access arguments like a stack, not an array. ... When accessing arguments for a syscall, the position of an argument depends on the policies of the ISA, how much space preceding arguments took up, and the "alignment" of the index for this particular argument into the number of possible storate locations. This change adjusts getSyscallArg to take its index parameter by reference instead of value and to adjust it to point to the possible location of the next argument on the stack, basically just after the current one. This way, the rules for the new argument can be applied locally without knowing about other arguments since those have already been taken into account implicitly. All system calls have also been changed to reflect the new interface. In a number of cases this made the implementation clearer since it encourages arguments to be collected in one place in order and then used as necessary later, as opposed to scattering them throughout the function or using them in place in long expressions. It also discourages using getSyscallArg over and over to retrieve the same value when a temporary would do the job.	2009-10-30 00:44:55 -07:00
Nathan Binkert	25d9328689	license: Fix license on network model code ... This mostly was a matter of changing the license owner to Princeton which is as it should have been.

Vince Weaver	56154cff5e	Enable getuid and getgid related syscalls on X86_SE ... I've tested these on x86 and they work as expected. In theory for 32-bit x86 we should have some sort of special handling for the legacy 16-bit uid/gid syscalls, but in practice modern toolchains don't use the 16-bit versions, and m5 sets the uid and gid values to be less than 16-bits anyway.

Gabe Black	6e97feb8a5	X86: Make not taken conditional moves leave the destination alone. Adjust CMOVcc. ... The manuals from both AMD and Intel say that when writing to a 32 bit destination in 64 bit mode, the upper 32 bits of the register are filled with zeros. They also both say that the CMOV instructions leave their destination alone when their condition fails. Unfortunately, it seems that CMOV will zero extend its destination register whether or not it was supposed to actually do a move on both platforms. This seems to be the only case where this happens, but it would be hard to say for sure.	2009-08-08 17:23:19 -07:00

Gabe Black	3a55fc5cac	X86: Implement shift right/left double microops. ... This is my best guess as far as what these should do. Other existing microops use implicit registers, mul1s and mul1u for instance, so this should be ok. The microop that loads the implicit DoubleBits register would fall into one of the microop slots for moving to/from special registers.	2009-08-07 10:13:20 -07:00

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
