Timothy M. Jones	9a3533ec84	O3CPU: O3's tick event gets squashed when it is switched out. When repeatedly ... switching between O3 and another CPU, O3's tick event might still be scheduled in the event queue (as squashed). Therefore, check for a squashed tick event as well as a non-scheduled event when taking over from another CPU and deal with it accordingly.	2010-07-22 18:47:43 +01:00
Timothy M. Jones	8c76715979	Power: Provide a utility function to copy registers from one thread context ... to another in the Power ISA.	2010-07-22 18:47:03 +01:00

Nathan Binkert	76c92c3e30	python: add a sorted dictionary class ... It would be nice if python had a tree class that would do this for real, but since we don't, we'll just keep a sorted list of keys and update it on demand.	2010-07-21 15:53:53 -07:00
Nathan Binkert	3518416917	python: Add mechanism to override code compiled into the exectuable ... If the user sets the environment variable M5_OVERRIDE_PY_SOURCE to True, then imports that would normally find python code compiled into the executable will instead first check in the absolute location where the code was found during the build of the executable. This only works for files in the src (or extras) directories, not automatically generated files. This is a developer feature!	2010-07-21 15:53:52 -07:00
Tushar Krishna	11bb678a80	Fix x86 XCHG macro-op to use locked micro-ops for all memory accesses	2010-07-21 09:55:57 -07:00
Steve Reinhardt	262b2e2b94	SimObject: transparently forward Python attribute refs to C++. ... This tidbit was pulled from a larger patch for Tim's sake, so the comment reflects functions that haven't been exported yet. I hope to commit them soon so it didn't seem worth cleaning up.	2010-07-17 08:56:49 -07:00

Steve Reinhardt	26f5a9c2cb	checkpointing: another small overload fix ... On Nate's advice, overload 'char' as well as 'signed char' and 'unsigned char'.	2010-07-05 22:57:23 -07:00
Steve Reinhardt	387cbffb7a	sim: allow SimObject subclasses to define classmethods ... (without requiring a leading underscore) Also a little cleanup on type names in SimObject.py.	2010-07-05 21:39:38 -07:00
Steve Reinhardt	30ce620d1d	sim: fold StartupCallback into SimObject ... There used to be a reason to have StartupCallback be a separate object, but not any more. Now it's just confusing.	2010-07-05 21:39:38 -07:00
Steve Reinhardt	345dfd1b41	checkpointing: minor cleanup. ... Move some static checkpoint stuff into the Checkpoint object namespace.	2010-07-05 21:39:38 -07:00
Steve Reinhardt	820bb3044d	checkpointing: fix minor bug ... Somehow we now need to explicitly specialize on 'signed char' and not just 'char' to catch cases like int8_t	2010-07-05 21:39:38 -07:00

Korey Sewell	792c18a1fc	inorder: remove debugging stat ... m5 doesnt do stats specific to binary and this resource request stat is probably only useful for people who really know the ins/outs of the model anyway	2010-06-26 09:41:39 -04:00
Korey Sewell	868181f24d	inorder: Return Address Stack bug ... the nextPC was getting sent to the branch predictor not the current PC, so the RAS was returning the wrong PC and mispredicting everything.	2010-06-25 17:42:35 -04:00
Korey Sewell	6bfd766f2c	inorder: resource scheduling backend ... replace priority queue with vector of lists(1 list per stage) and place inside a class so that we have more control of when an instruction uses a particular schedule entry ... also, this is the 1st step toward making the InOrderCPU fully parameterizable. See the wiki for details on this process	2010-06-25 17:42:34 -04:00

Korey Sewell	1f778b3583	inorder: record load/store trace data	2010-06-23 18:21:12 -04:00
Korey Sewell	defab3ffd5	inorder: update branch predictor ... - use InOrderBPred instead of Resource for DPRINTFs - account for DELAY SLOT in updating RAS and in squashing - don't let squashed instructions update the predictor - the BTB needs to use the ASID not the TID to work for multithreaded programs - add stats for BTB hits	2010-06-23 18:19:18 -04:00
Korey Sewell	9f0d8f252c	inorder-stats: add instruction type stats ... also, remove inst-req stats as default.good for debugging but in terms of pure processor stats they aren't useful	2010-06-23 18:18:20 -04:00

Timothy M. Jones	96767fc721	O3ThreadContext: When taking over from a previous context, only assert that ... the system pointers match in Full System mode.	2010-06-23 00:53:17 +01:00
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	5fc7adcba0	python: use ipython in --interactive if it is available	2010-06-14 23:24:46 -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	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	f92e91e853	Minor remote GDB cleanup. ... Expand the help text on the --remote-gdb-port option so people know you can use it to disable remote gdb without reading the source code, and thus don't waste any time trying to add a separate option to do that. Clean up some gdb-related cruft I found while looking for where one would add a gdb disable option, before I found the comment that told me that I didn't need to do that.	2010-06-03 16:54:26 -07:00

Gabe Black	b6e2f5d33f	ARM: Make sure ldm exception return writes back its base in the right mode. ... This change moves the writeback of load multiple instructions to the beginning of the macroop. That way, the MicroLdrRetUop that changes the mode will necessarily happen later, ensuring the writeback happens in the original mode. The actual value in the base register if it also shows up in the register list is undefined, so it's fine if it gets clobbered by one of the loads. For stores where the base register is the lowest numbered in the register list, the original value should be written back. That means stores can't write back at the beginning, but the mode changing problem doesn't affect them so they can continue to write back at the end.	2010-06-02 12:58:04 -05:00
Gabe Black	89060f1fd8	ARM: Rework how unrecognized/unimplemented instructions are handled. ... Instead of panic immediately when these instructions are executed, an UndefinedInstruction fault is returned. In FS mode (not currently implemented), this is the fault that should, to my knowledge, be triggered in these situations and should be handled using the normal architected mechanisms. In SE mode, the fault causes a panic when it's invoked that gives the same information as the instruction did. When/if support for speculative execution of ARM is supported, this will allow a mispeculated and unrecognized and/or unimplemented instruction from causing a panic. Only once the instruction is going to be committed will the fault be invoked, triggering the panic.	2010-06-02 12:58:04 -05:00

Gabe Black	14d25fbad0	ARM: Don't rely on undefined behavior to get arithmetic right shift. ... Shifting to the right of a signed value when the MSB is one is technically undefined behavior, even though in my experience it's done the "right thing" and sign extended the value. This replaces the arithmetic right shift code in ARM that uses that coincidence with some code that relies on bit math.	2010-06-02 12:58:04 -05:00

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

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

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

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. ...

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	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.

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.

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

It fixes the problem in the previous version (pointed out by Gabe Black) where an incorrect result would happen if you issue the instruction with the same argument twice, i.e. "haddpd %xmm0,%xmm0" This instruction is used by many spec2k benchmarks.	2009-10-30 14:19:06 -04:00
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
