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

Maximilien Breughe	fc746c2268	BPRED: Fixed the treshold-bug in the tournament predictor. ... Suppose the saturating counters of a branch predictor contain n bits. When the counter is between 0 and (2^(n-1) - 1), boundaries included, the branch is predicted as not taken. When the counter is between 2^(n-1) and (2^n - 1), boundaries included, the branch is predicted as taken.	2010-05-13 23:45:57 -04:00
Gabe Black	c4497dbf03	X86: Make the cvti2f microop sign extend its integer source correctly. ... The code was using the wrong bit as the sign bit. Other similar bits of code seem to be correct.	2010-05-12 00:51:35 -07:00
Gabe Black	cc76842f83	X86: Actual change that fixes div. How did that happen?	2010-05-12 00:49:12 -07:00
Nathan Binkert	c4057a13f1	macos: MacOS has deprecated getdirentries, so just disable the code. ... Hopefully it isn't used much	2010-05-06 08:42:21 -07:00
Nathan Binkert	f07ee128cc	compile: don't #include unnecessary stuff ... Time from base/time.hh has a name clash with Time from Ruby's TypeDefines.hh. Eventually Ruby's Time should go away, so instead of fixing this properly just try to avoid the clash.	2010-05-06 08:42:18 -07:00
Gabe Black	2ee7a89209	X86: Update the base aux vector X86 processes install.	2010-05-03 00:44:08 -07:00
Gabe Black	7524fdda6a	X86: Sometimes CPUID depends on ecx, so pass that in.	2010-05-02 00:40:17 -07:00
Gabe Black	51a3d65e25	X86: Finally fix a division corner case. ... When doing an unsigned 64 bit division with a divisor that has its most significant bit set, the division code would spill a bit off of the end of a uint64_t trying to shift the dividend into position. This change adds code that handles that case specially by purposefully letting it spill and then going ahead assuming there was a 65th one bit.	2010-05-02 00:39:29 -07:00
Nathan Binkert	82fb350f9a	stats: make simTicks and simFreq accessible from stats.hh	2010-04-18 13:23:25 -07:00
Nathan Binkert	50bf3895b0	callback: Make helper functions that create callback objects for you ... clean up callback stuff a little bit while we're at it.	2010-04-18 13:23:25 -07:00
Nathan Binkert	12fc22571c	event: Allow EventWrapper to take an object reference	2010-04-18 13:23:24 -07:00
Nathan Binkert	4225a68a95	scons: don't maintain files in sorted order ... This causes builds to happen in sorted order rather than in declaration order. This gets annoying when you make a global change and then you notice that the files that are being compiled are jumping around the directory hierarchy.	2010-04-15 16:25:14 -07:00
Nathan Binkert	e99828b06a	tick: rename Clock namespace to SimClock	2010-04-15 16:24:12 -07:00
Nathan Binkert	f7e6f19ada	eventq: move EventQueue constructor to cc file ... Also make copy constructor and assignment operator private.	2010-04-15 16:24:10 -07:00
Korey Sewell	b49511ae48	inorder: timing for inst forwarding ... when insts execute, they mark the time they finish to be used for subsequent isnts they may need forwarding of data. However, the regdepmap was using the wrong value to index into the destination operands of the instruction to be forwarded. Thus, in some cases, we are checking to see if the 3rd destination register for an instruction is executed at a certain time, when there is only 1 dest. register valid. Thus, we get a bad, uninitialized time value that will stall forwarding causing performance loss but still the correct execution.	2010-04-10 23:31:36 -04:00
Nathan Binkert	d71f9712b3	eventq: allow an implicit cast from an EventManager to an EventQueue *	2010-04-02 15:28:22 -07:00
Nathan Binkert	f32674d9bc	eventq: Clean up some flags ... - Make the initialized flag always available, not just in debug mode. - Make the Initialized flag actually use several bits so it is very unlikely that something that's uninitialized accidentally looks initialized. - Add an initialized() function that tells you if the current event is indeed initialized. - Clear the flags on delete so it can't be accidentally thought of as initialized. - Fix getFlags assert statement. "How did this ever work?"	2010-04-02 15:28:22 -07:00
Nathan Binkert	2ee3edba8e	eventq: Make priorities just an integer instead of an enum. ... Symbolic names should still be used, but this makes it easier to do things like: Event::Priority MyObject_Pri = Event::Default_Pri + 1 Remember that higher numbers are lower priority (should we fix this?)	2010-04-02 15:28:21 -07:00
Nathan Binkert	01dffaa32f	refcnt: no default copy contructor or copy operator ... We shouldn't allow these because the default versions will copy the reference count which is definitely not what we want.	2010-04-02 11:20:32 -07:00
Nathan Binkert	141f61d83a	ruby: get rid of gems_common/util.hh and .cc and use stuff in src/base	2010-04-02 11:20:32 -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

Korey Sewell	ac316d45e8	inorder: write-hints bug fix ... make sure to only read 1 src reg. for write-hint and any other similar 'store' instruction. Reading the source reg when its not necessary can cause the simulator to read from uninitialized values	2010-03-27 01:40:05 -04:00
Timothy M. Jones	6b293c73fd	CPU: Added comments to address translation classes.	2010-03-25 12:43:52 +00:00

Steve Reinhardt	f066bfc2f5	cpu: get rid of uncached access "events" ... These recordEvent() calls could cause crashes since they access the req pointer after it's potentially been deleted during a failed translation call. (Similar problem to the traceData bug fixed in the previous cset.) Moving them above the translation call (as was done recentlyi in cset 8b2b8e5e7d35) avoids the crash but doesn't work, since at that point we don't know if the access is uncached or not. It's not clear why these calls are there, and no one seems to use them, so we'll just delete them. If they are needed, they should be moved to somewhere that's guaranteed to be after the translation completes but before the request is possibly deleted, e.g., in finishTranslation().	2010-03-23 08:50:59 -07:00
Steve Reinhardt	4d77ea7a57	cpu: fix exec tracing memory corruption bug ... Accessing traceData (to call setAddress() and/or setData()) after initiating a timing translation was causing crashes, since a failed translation could delete the traceData object before returning. It turns out that there was never a need to access traceData after initiating the translation, as the traced data was always available earlier; this ordering was merely historical. Furthermore, traceData->setAddress() and traceData->setData() were being called both from the CPU model and the ISA definition, often redundantly. This patch standardizes all setAddress and setData calls for memory instructions to be in the CPU models and not in the ISA definition. It also moves those calls above the translation calls to eliminate the crashes.	2010-03-23 08:50:57 -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
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

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

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

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. The code was originally licensed under the GPL but was relicensed as BSD by Li-Shiuan Peh on July 27, 2009. This relicensing was in an explicit e-mail to Nathan Binkert, Brad Beckmann, Mark Hill, David Wood, and Steve Reinhardt.	2009-10-28 11:56:56 -07:00

Vince Weaver	14691148cd	Implement X86 sse2 movdqu and movdqa instructions ... The movdqa instruction should enforce 16-byte alignment. This implementation does not do that. These instructions are needed for most of x86_64 spec2k to run.	2009-10-21 13:40:43 -04:00

In the simulator, if the new page exists, it will be cleared using this patch, to mimic the kernel's functionality.	2009-10-24 10:53:58 -07:00

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. This fix is needed for the perl spec2k benchmarks to run.	2009-10-19 17:29:34 -04:00

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

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
