2013-06-24stats: Bump x86 statsAndreas Hansson
This patch bumps the x86 stats to reflect the recent fixes.
2013-06-10stats: updates due to changes to rubyNilay Vaish
Ruby's controller statistics have been mostly moved to stats.txt now. Plus stats.txt for solaris/t1000-simple-atomic and arm/20.parser are also being updated.

2013-05-30stats: Update the stats to reflect bus and memory changesAndreas Hansson
This patch updates the stats to reflect the addition of the bus stats, and changes to the bus layers. In addition it updates the stats to match the addition of the static pipeline latency of the memory conotroller and the addition of a stat tracking the bytes per activate.
2013-05-30mem: More descriptive DRAM config namesAndreas Hansson
This patch changes the class names of the variuos DRAM configurations to better reflect what memory they are based on. The speed and interface width is now part of the name, and also the alias that is used to select them on the command line. Some minor changes are done to the actual parameters, to better reflect the named configurations. As a result of these changes the regressions change slightly and the stats will be bumped in a separate patch.

2013-04-22config: Add a mem-type config option to se/fs scriptsAndreas Hansson
This patch enables selection of the memory controller class through a mem-type command-line option. Behind the scenes, this option is treated much like the cpu-type, and a similar framework is used to resolve the valid options, and translate the short-hand description to a valid class. The regression scripts are updated with a hardcoded memory class for the moment. The best solution going forward is probably to get the memory out of the makeSystem functions, but Ruby complicates things as it does not connect the memory controller to the membus. --HG-- rename : configs/common/CpuConfig.py => configs/common/MemConfig.py
2013-04-22stats: Update stats for O3 switching fix.Ali Saidi
2013-04-22tests: Add support for testing KVM-based CPUsAndreas Sandberg
This changeset adds support for initializing a KVM VM in the BaseSystem test class and adds the following methods in run.py: require_file -- Test if a file exists and abort/skip if not. require_kvm -- Test if KVM support has been compiled into gem5 (i.e., BaseKvmCPU exists) and the KVM device exists on the host.
2013-04-22arm: Enable support for triggering a sim panic on kernel panicsAndreas Sandberg
Add the options 'panic_on_panic' and 'panic_on_oops' to the LinuxArmSystem SimObject. When these option are enabled, the simulator panics when the guest kernel panics or oopses. Enable panic on panic and panic on oops in ARM-based test cases.
2013-04-19stats: Update stats for ldr_ret_uop (changeset 35198406dd72)Andreas Hansson
This patch merely bumps the stats to match the changes introduced in changeset 35198406dd72.
2013-04-16stats: Bump the vortex stats to match latest behaviourAndreas Hansson
This patch bumps the stats for the failing vortex o3 regression.
2013-04-09stats: Bump Ruby stats for new changesetsJoel Hestness
The new changeset that can reorder Ruby profilers will cause the ruby.stats files to reordered statistics (the point of the patch). Update the references to ensure that these changes are reflected in regressions.

2013-02-15config: Move CPU handover logic to m5.switchCpus()Andreas Sandberg
CPU switching consists of the following steps: 1. Drain the system 2. Switch out old CPUs (cpu.switchOut()) 3. Change the system timing mode to the mode the new CPUs require 4. Flush caches if switching to hardware virtualization 5. Inform new CPUs of the handover (cpu.takeOverFrom()) 6. Resume the system m5.switchCpus() previously only did step 2 & 5. Since information about the new processors' memory system requirements is now exposed, do all of the steps above. This patch adds automatic memory system switching and flush (if needed) to switchCpus(). Additionally, it adds optional draining to switchCpus(). This has the following implications: * changeToTiming and changeToAtomic are no longer needed, so they have been removed. * changeMemoryMode is only used internally, so it is has been renamed to be private. * switchCpus requires a reference to the system containing the CPUs as its first parameter. WARNING: This changeset breaks compatibility with existing configuration scripts since it changes the signature of m5.switchCpus().

2013-01-31stats: Update stats for regressions using SimpleDDR3Andreas Hansson
This patch updates the regression stats to reflect that they are using the SimpleDDR3 controller by default.
2013-01-31mem: Add DDR3 and LPDDR2 DRAM controller configurationsAndreas Hansson
This patch moves the default DRAM parameters from the SimpleDRAM class to two different subclasses, one for DDR3 and one for LPDDR2. More can be added as we go forward. The regressions that previously used the SimpleDRAM are now using SimpleDDR3 as this is the most similar configuration.
2013-01-28stats: Fix naming (BPredUnit to branchPred) for 20.parser ARM o3Andreas Hansson
This patch bumps the stats for 20.parser for ARM o3-timing to reflect a namechange of the branch predictor.
2013-01-24regressions: update stats due to branch predictor changesNilay Vaish
The actual statistical values are being updated for only two tests belonging to sparc architecture and inorder cpu: 00.hello and 02.insttest. For others the patch updates config.ini and name changes to statistical variables.

2013-01-07tests: Add CPU switching testsAndreas Sandberg
This changeset adds a set of tests that stress the CPU switching code. It adds the following test configurations: * tsunami-switcheroo-full -- Alpha system (atomic, timing, O3) * realview-switcheroo-atomic -- ARM system (atomic<->atomic) * realview-switcheroo-timing -- ARM system (timing<->timing) * realview-switcheroo-o3 -- ARM system (O3<->O3) * realview-switcheroo-full -- ARM system (atomic, timing, O3) Reference data is provided for the 10.linux-boot test case. All of the tests trigger a CPU switch once per millisecond during the boot process. The in-order CPU model was not included in any of the tests as it does not support CPU handover.
2013-01-07tests: Update the ignore regexps to reflect the M5->gem5 name changeAndreas Sandberg
2013-01-07config: Do not use hardcoded physmem in fs scriptAndreas Hansson
This patch generalises the address range resolution for the I/O cache and I/O bridge such that they do not assume a single memory. The patch involves adding a parameter to the system which is then defined based on the memories that are to be visible from the I/O subsystem, whether behind a cache or a bridge. The change is needed to allow interleaved memory controllers in the system.
2013-01-07cpu: Add support for protobuf input for the trace generatorAndreas Hansson
This patch adds support for reading input traces encoded using protobuf according to what is done in the CommMonitor. A follow-up patch adds a Python script that can be used to convert the previously used ASCII traces to protobuf equivalents. The appropriate regression input is updated as part of this patch.
2013-01-07tests: Add support for skipping tests, skip EIO tests if not enabledAndreas Sandberg
The EIO tests depend on the EIO support from the "encumbered" repository, which means that they are not normally built with gem5. This causes all EIO related tests to fail, which is both annoying and confusing. This patch addresses this by adding support for skipping tests if certain conditions (e.g., the presence of a SimObject) can not be met. It introduces the following Python functions that can be called from within a test case: * skip_test -- Skip a test and optionally print why the test was skipped. * has_sim_object -- Test if a SimObject exists. * require_sim_object -- Test if a SimObject exists and skip, or optionally fail, the test if not. Additionally, this patch updates the EIO tests to check for the presence of EioProcess.
2013-01-07mem: Add tracing support in the communication monitorAndreas Hansson
This patch adds packet tracing to the communication monitor using a protobuf as the mechanism for creating the trace. If no file is specified, then the tracing is disabled. If a file is specified, then for every packet that is successfully sent, a protobuf message is serialized to the file.
2013-01-07stats: Update DRAM regression stats to match new configAndreas Hansson
This patch updates the regression stats to reflect the change in the traffic gen configuration.
2013-01-07config: Reduce DRAM controller regression traffic rateAndreas Hansson
This patch changes the traffic generator period such that it does not completely saturate the DRAM controller and create an ever-growing backlog in the queued port. A separate patch updates the stats.
2013-01-07arch: Make the ISA class inherit from SimObjectAndreas Sandberg
The ISA class on stores the contents of ID registers on many architectures. In order to make reset values of such registers configurable, we make the class inherit from SimObject, which allows us to use the normal generated parameter headers. This patch introduces a Python helper method, BaseCPU.createThreads(), which creates a set of ISAs for each of the threads in an SMT system. Although it is currently only needed when creating multi-threaded CPUs, it should always be called before instantiating the system as this is an obvious place to configure ID registers identifying a thread/CPU.
