2015-03-23misc: quote args in echoed command lineSteve Reinhardt
Currently if there are shell special characters in a command-line argument, you can't copy and paste the echoed command line onto a shell prompt because the characters aren't quoted properly. This patch fixes that problem.
2015-03-23config: Add ability to exit simulation after initializationCurtis Dunham
When using gem5 as a slave simulator, it will not advance the clock on its own and depends on the master simulator calling simulate(). This new option lets us use the Python scripts to do all the configuration while stopping short of actually simulating anything.
2015-03-23sim: Reuse the same limit_event in simulate()Curtis Dunham
This patch accomplishes two things: 1. Makes simulate()'s GlobalSimLoopExitEvent a singleton reused across calls. This is slightly more efficient than recreating it every time. 2. Gives callers to simulate() (especially other simulators) a foolproof way of knowing that the simulation period ended successfully by hitting the limit event. They can call getLimitEvent() and compare it to the return value of simulate(). This change was motivated by an ongoing effort to integrate gem5 and SST, with SST as the master sim and gem5 as the slave sim.
2015-03-23mem: Tidy up RequestAndreas Hansson
This patch does a bit of house keeping, fixing up typos, removing dead code etc.
2015-03-23tests: Final reclassification of quick regressionsAndreas Hansson
A few regressions were still considered long, but finished well within the 180 seconds.

2015-03-19stats: update Minor stats due to PF bug fixSteve Reinhardt
A recent changeset of mine (http://repo.gem5.org/gem5/rev/4cfe55719da5) inadvertently fixed a bug in the Minor CPU model which caused it to treat software prefetches as regular loads. Prior to this changeset, Minor did an ad-hoc generation of memory commands that left out the PF check; because it now uses the common code that the other CPU models use, it generates prefetches properly. These stat changes reflect the fact that the Minor model now issues SoftPFReqs.
2015-03-19tests: Recategorise regressions based on run timeAndreas Hansson
This patch takes a first stab at recategorising the regression tests based on actual run times. The simple-atomic and simple-timing runs of vortex and twolf all finish in less than 180 s, and they are consequently moved from long to quick. All realview64 linux-boot regressions take more than 700 s, and they are therefore moved to long. Later patches will rename quick to short, and further divide the regressions into short, medium and long. --HG-- rename :

2015-03-19test, arm: Add scripts to test checkpointsAndreas Sandberg
Add a set of scripts to automatically test checkpointing in the regression framework. The checkpointing tests are similar to the switcheroo tests, but instead of switching between CPUs, they checkpoint the system and restore from the checkpoint again. This is done at regular intervals, typically while booting Linux. The implementation is fairly straight forward, with the exception that we have to work around gem5's inability to restore from a checkpoint after a system has been instantiated. We work around this by forking off child processes that does the actual simulation and never instantiate a system in the parent process unless a maximum checkpoint count is reached (in which case we just simulate the system to completion in the parent). Checkpoint testing is currently only enabled 32- and 64-bit ARM systems using atomic CPUs. Note: An unfortunate side-effect of forking is that every new process will overwrite the stats and terminal output from the previous process. This means that the output directory only contains data from the last checkpoint.
2015-03-19config: Add soak test for memtest.pyAndreas Hansson
This patch adds a random option to memtest.py which allows the user to easily test valid random tree topologies. The patch also adds a wrapper script to run soak tests using the newly introduced option. We also adjust the progress interval and progress limit check to make the output less noisy, and avoid false positives. Bring on the pain.
2015-03-19arm: Add a GICv2m deviceMatt Evans
This patch adds a new PIO-accessible GICv2m shim. This shim has a PIO slave port on one side, and SPI 'wires' on the other. It accepts MSIs from the system and triggers SPIs on the GIC. It is configurable with a number of frames, each of which has a number of SPIs and a base SPI offset. A Linux driver for GICv2m is available upstream.
2015-03-19arm: Remove the 'magic MSI register' in the GIC (PL390)Matt Evans
This patch removes the code that added this magic register. A follow-up patch provides a GICv2m MSI shim that gives the same functionality in a standard ARM system architecture way.
2015-03-19config: Specify OS type and release on command lineChris Emmons
This patch enables users to speficy --os-type on the command line. This option is used to take specific actions for an OS type, such as changing the kernel command line. This patch is part of the Android KitKat enablement.
2015-03-19cpu: Fix TrafficGen message formatWendy Elsasser
Fix erroneous message format for fatal error. Previously, code did not have type indicator (% instead of %d). Also removed redundant fatal check. Ran modified sweep.py with in range and out of range values to test.
2015-03-19mem: Use emplace front/back for deferred packetsAndreas Hansson
Embrace C++11 for the deferred packets as we actually store the objects in the data structure, and not just pointers.
2015-03-19mem: Enable CommMonitor to output traces in atomic modeGeoffrey Blake
The CommMonitor by default only allows memory traces to be gathered in timing mode. This patch allows memory traces to be gathered in atomic mode if all one needs is a functional trace of memory addresses used and timing information is of a secondary concern.
2015-03-19config: Fix DRAM rank option in sweep scriptAndreas Hansson

2015-02-11mem: remove redundant test in in Cache::recvTimingResp()Steve Reinhardt
For some reason we were checking mshr->hasTargets() even though we had already called mshr->getTarget() unconditionally earlier in the same function (which asserts if there are no targets). Get rid of this useless check, and while we're at it get rid of the redundant call to mshr->getTarget(), since we still have the value saved in a local var.
2015-02-11mem: add local var in Cache::recvTimingResp()Steve Reinhardt
The main loop in recvTimingResp() uses target->pkt all over the place. Create a local tgt_pkt to help keep lines under the line length limit.
2015-02-11mem: restructure Packet cmd initialization a bit moreSteve Reinhardt
Refactor the way that specific MemCmd values are generated for packets. The new approach is a little more elegant in that we assign the right value up front, and it's also more amenable to non-heap-allocated Packet objects. Also replaced the code in the Minor model that was still doing it the ad-hoc way. This is basically a refinement of http://repo.gem5.org/gem5/rev/711eb0e64249.
2015-03-14mem: clean up write buffer check in Cache::handleSnoop()Steve Reinhardt
The 'if (writebacks.size)' check was redundant, because writeBuffer.findMatches() would return false if the writebacks list was empty. Also renamed 'mshr' to 'wb_entry' in this context since we are pointing at a writebuffer entry and not an MSHR (even though it's the same C++ class).

2015-03-07stats: update eio statsSteve Reinhardt
Minor differences apparently from recent changes
2015-03-02stats: Update stats to reflect cache and interconnect changesAndreas Hansson
This is a bulk update of stats to match the changes to cache timing, interconnect timing, and a few minor changes to the o3 CPU.
2015-03-02mem: Unify all cache DPRINTF address formattingAndreas Hansson
This patch changes all the DPRINTF messages in the cache to use '%#llx' every time a packet address is printed. The inclusion of '#' ensures '0x' is prepended, and since the address type is a uint64_t %x really should be %llx.
2015-03-02mem: Fix cache MSHR conflict determinationAndreas Hansson
This patch fixes a rather subtle issue in the sending of MSHR requests in the cache, where the logic previously did not check for conflicts between the MSRH queue and the write queue when requests were not ready. The correct thing to do is to always check, since not having a ready MSHR does not guarantee that there is no conflict. The underlying problem seems to have slipped past due to the symmetric timings used for the write queue and MSHR queue. However, with the recent timing changes the bug caused regressions to fail.
2015-03-02mem: Add byte mask to Packet::checkFunctionalAndreas Hansson
This patch changes the valid-bytes start/end to a proper byte mask. With the changes in timing introduced in previous patches there are more packets waiting in queues, and there are regressions using the checker CPU failing due to non-contigous read data being found in the various cache queues. This patch also adds some more comments explaining what is going on, and adds the fourth and missing case to Packet::checkFunctional.
2015-03-02mem: Add option to force in-order insertion in PacketQueueStephan Diestelhorst
By default, the packet queue is ordered by the ticks of the to-be-sent packages. With the recent modifications of packages sinking their header time when their resposne leaves the caches, there could be cases of MSHR targets being allocated and ordered A, B, but their responses being sent out in the order B,A. This led to inconsistencies in bus traffic, in particular the snoop filter observing first a ReadExResp and later a ReadRespWithInv. Logically, these were ordered the other way around behind the MSHR, but due to the timing adjustments when inserting into the PacketQueue, they were sent out in the wrong order on the bus, confusing the snoop filter. This patch adds a flag (off by default) such that these special cases can request in-order insertion into the packet queue, which might offset timing slighty. This is expected to occur rarely and not affect timing results.
2015-03-02mem: Downstream components consumes new crossbar delaysMarco Balboni
This patch makes the caches and memory controllers consume the delay that is annotated to a packet by the crossbar. Previously many components simply threw these delays away. Note that the devices still do not pay for these delays.
2015-03-02mem: Move crossbar default latencies to subclassesAndreas Hansson
This patch introduces a few subclasses to the CoherentXBar and NoncoherentXBar to distinguish the different uses in the system. We use the crossbar in a wide range of places: interfacing cores to the L2, as a system interconnect, connecting I/O and peripherals, etc. Needless to say, these crossbars have very different performance, and the clock frequency alone is not enough to distinguish these scenarios. Instead of trying to capture every possible case, this patch introduces dedicated subclasses for the three primary use-cases: L2XBar, SystemXBar and IOXbar. More can be added if needed, and the defaults can be overridden.
2015-03-02mem: Add crossbar latenciesMarco Balboni
This patch introduces latencies in crossbar that were neglected before. In particular, it adds three parameters in crossbar model: front_end_latency, forward_latency, and response_latency. Along with these parameters, three corresponding members are added: frontEndLatency, forwardLatency, and responseLatency. The coherent crossbar has an additional snoop_response_latency. The latency of the request path through the xbar is set as --> frontEndLatency + forwardLatency In case the snoop filter is enabled, the request path latency is charged also by look-up latency of the snoop filter. --> frontEndLatency + SF(lookupLatency) + forwardLatency. The latency of the response path through the xbar is set instead as --> responseLatency. In case of snoop response, if the response is treated as a normal response the latency associated is again --> responseLatency; If instead it is forwarded as snoop response we add an additional variable + snoopResponseLatency and the latency associated is --> snoopResponseLatency; Furthermore, this patch lets the crossbar progress on the next clock edge after an unused retry, changing the time the crossbar considers itself busy after sending a retry that was not acted upon.
2015-03-02dev, arm: Clean up PL011 and rewrite interrupt handlingAndreas Sandberg
The ARM PL011 UART model didn't clear and raise interrupts correctly. This changeset rewrites the whole interrupt handling and makes it both simpler and fixes several cases where the correct interrupts weren't raised or cleared. Additionally, it cleans up many other aspects of the code.
2015-03-02arm: Share a port for the two table walker objectsAndreas Hansson
This patch changes how the MMU and table walkers are created such that a single port is used to connect the MMU and the TLBs to the memory system. Previously two ports were needed as there are two table walker objects (stage one and stage two), and they both had a port. Now the port itself is moved to the Stage2MMU, and each TableWalker is simply using the port from the parent. By using the same port we also remove the need for having an additional crossbar joining the two ports before the walker cache or the L2. This simplifies the creation of the CPU cache topology in BaseCPU.py considerably. Moreover, for naming and symmetry reasons, the TLB walker port is connected through the stage-one table walker thus making the naming identical to x86. Along the same line, we use the stage-one table walker to generate the master id that is used by all TLB-related requests.
2015-03-02arm: Remove unnecessary dependencies between AArch64 FP instructionsGiacomo Gabrielli
2015-03-02cpu: o3 register renaming request handling improvedRekai
Now, prior to the renaming, the instruction requests the exact amount of registers it will need, and the rename_map decides whether the instruction is allowed to proceed or not.
2015-03-02mem: Tidy up the cache debug messagesAndreas Hansson
Avoid redundant inclusion of the name in the DPRINTF string.
2015-03-02mem: Split port retry for all different packet classesAndreas Hansson
This patch fixes a long-standing isue with the port flow control. Before this patch the retry mechanism was shared between all different packet classes. As a result, a snoop response could get stuck behind a request waiting for a retry, even if the send/recv functions were split. This caused message-dependent deadlocks in stress-test scenarios. The patch splits the retry into one per packet (message) class. Thus, sendTimingReq has a corresponding recvReqRetry, sendTimingResp has recvRespRetry etc. Most of the changes to the code involve simply clarifying what type of request a specific object was accepting. The biggest change in functionality is in the cache downstream packet queue, facing the memory. This queue was shared by requests and snoop responses, and it is now split into two queues, each with their own flow control, but the same physical MasterPort. These changes fixes the previously seen deadlocks.
2015-03-02mem: Fix prefetchSquash + memInhibitAsserted bugAli Jafri
This patch resolves a bug with hardware prefetches. Before a hardware prefetch is sent towards the memory, the system generates a snoop request to check all caches above the prefetch generating cache for the presence of the prefetth target. If the prefetch target is found in the tags or the MSHRs of the upper caches, the cache sets the prefetchSquashed flag in the snoop packet. When the snoop packet returns with the prefetchSquashed flag set, the prefetch generating cache deallocates the MSHR reserved for the prefetch. If the prefetch target is found in the writeback buffer of the upper cache, the cache sets the memInhibit flag, which signals the prefetch generating cache to expect the data from the writeback. When the snoop packet returns with the memInhibitAsserted flag set, it marks the allocated MSHR as inService and waits for the data from the writeback. If the prefetch target is found in multiple upper level caches, specifically in the tags or MSHRs of one upper level cache and the writeback buffer of another, the snoop packet will return with both prefetchSquashed and memInhibitAsserted set, while the current code is not written to handle such an outcome. Current code checks for the prefetchSquashed flag first, if it finds the flag, it deallocates the reserved MSHR. This leads to assert failure when the data from the writeback appears at cache. In this fix, we simply switch the order of checks. We first check for memInhibitAsserted and then for prefetch squashed.
2015-03-02cpu: Add a PC-value to the traffic generator requestsStephan Diestelhorst
Have the traffic generator add its masterID as the PC address to the requests. That way, prefetchers (and other components) that use a PC for request classification will see per-tester streams of requests. This enables us to test strided prefetchers with the memchecker, too.
2015-03-02tests: Run regression timeout as foregroundAndreas Hansson
Allow the user to send signals such as Ctrl C to the gem5 runs. Note that this assumes coreutils >= 8.13, which aligns with Ubuntu 12.04 and RHE6.
2015-03-02arm: Don't truncate 16-bit ASIDs to 8 bitsAndreas Sandberg
The ISA code sometimes stores 16-bit ASIDs as 8-bit unsigned integers and has a couple of inverted checks that mask out the high 8 bits of an ASID if 16-bit ASIDs have been /enabled/. This changeset fixes both of those issues.
