Gabe Black	1fcd389fa3	ARM: Make sure macroops aren't interrupted midinstruction. ... Do this by setting the delayed commit flag for all but the last microop.	2010-06-02 12:58:12 -05:00
Gabe Black	67766cbf17	ARM: Fix the implementation of the VFP ldm and stm macroops. ... There were four bugs in these instructions. First, the loaded value was being stored into a floating point register as floating point, changing the value as it was transfered. Second, the meaning of the "up" bit had been reversed. Third, the statically sized microop array wasn't bit enough for all possible inputs. It's now dynamically sized and should always be big enough. Fourth, the offset was stored as an unsigned 8 bit value. Negative offsets would look like moderately large positive offsets.	2010-06-02 12:58:12 -05:00

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

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

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

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
