2013-08-19stats: Cumulative stats updateAndreas Hansson
This patch updates the stats to reflect the: 1) addition of the internal queue in SimpleMemory, 2) moving of the memory class outside FSConfig, 3) fixing up of the 2D vector printing format, 4) specifying burst size and interface width for the DRAM instead of relying on cache-line size, 5) performing merging in the DRAM controller write buffer, and 6) fixing how idle cycles are counted in the atomic and timing CPU models. The main reason for bundling them up is to minimise the changeset size.
2013-08-19mem: Change AbstractMemory defaults to match the common caseAndreas Hansson
This patch changes the default parameter value of conf_table_reported to match the common case. It also simplifies the regression and config scripts to reflect this change.
2013-08-19power: Add voltage domains to the clock domainsAkash Bagdia
This patch adds the notion of voltage domains, and groups clock domains that operate under the same voltage (i.e. power supply) into domains. Each clock domain is required to be associated with a voltage domain, and the latter requires the voltage to be explicitly set. A voltage domain is an independently controllable voltage supply being provided to section of the design. Thus, if you wish to perform dynamic voltage scaling on a CPU, its clock domain should be associated with a separate voltage domain. The current implementation of the voltage domain does not take into consideration cases where there are derived voltage domains running at ratio of native voltage domains, as with the case where there can be on-chip buck/boost (charge pumps) voltage regulation logic. The regression and configuration scripts are updated with a generic voltage domain for the system, and one for the CPUs.
2013-08-19config: Move the memory instantiation outside FSConfigAndreas Hansson
This patch moves the instantiation of the memory controller outside FSConfig and instead relies on the mem_ranges to pass the information to the caller (e.g. fs.py or one of the regression scripts). The main motivation for this change is to expose the structural composition of the memory system and allow more tuning and configuration without adding a large number of options to the makeSystem functions. The patch updates the relevant example scripts to maintain the current functionality. As the order that ports are connected to the memory bus changes (in certain regresisons), some bus stats are shuffled around. For example, what used to be layer 0 is now layer 1. Going forward, options will be added to support the addition of multi-channel memory controllers.

The statistics for 30.eio-mp, pc-simple-timing-ruby tests are being updated to incorporate the changes due to recent patches.
2013-07-02regressions: update a couple of configsNilay Vaish
The configs for pc-simple-timing-ruby, t1000-simple-atomic had not been updated correctly in the patch 6e6cefc1db1f.
2013-06-27stats: Update stats for monitor, cache and bus changesAndreas Hansson
This patch removes the sparse histogram total from the CommMonitor stats. It also bumps the stats after the unit fixes in the atomic cache access. Lastly, it updates the stats to match the new port ordering. All numbers are the same, and the only thing that changes is which master corresponds to what port index.
2013-06-27sim: Add the notion of clock domains to all ClockedObjectsAkash Bagdia
This patch adds the notion of source- and derived-clock domains to the ClockedObjects. As such, all clock information is moved to the clock domain, and the ClockedObjects are grouped into domains. The clock domains are either source domains, with a specific clock period, or derived domains that have a parent domain and a divider (potentially chained). For piece of logic that runs at a derived clock (a ratio of the clock its parent is running at) the necessary derived clock domain is created from its corresponding parent clock domain. For now, the derived clock domain only supports a divider, thus ensuring a lower speed compared to its parent. Multiplier functionality implies a PLL logic that has not been modelled yet (create a separate clock instead). The clock domains should be used as a mechanism to provide a controllable clock source that affects clock for every clocked object lying beneath it. The clock of the domain can (in a future patch) be controlled by a handler responsible for dynamic frequency scaling of the respective clock domains. All the config scripts have been retro-fitted with clock domains. For the System a default SrcClockDomain is created. For CPUs that run at a different speed than the system, there is a seperate clock domain created. This domain incorporates the CPU and the associated caches. As before, Ruby runs under its own clock domain. The clock period of all domains are pre-computed, such that no virtual functions or multiplications are needed when calling clockPeriod. Instead, the clock period is pre-computed when any changes occur. For this to be possible, each clock domain tracks its children.
2013-06-27config: Add a BaseSESystem builder for re-use in regressionsAndreas Hansson
This patch extends the existing system builders to also include a syscall-emulation builder. This builder is deployed in all syscall-emulation regressions that do not involve Ruby, i.e. o3-timing, simple-timing and simple-atomic, as well as the multi-processor regressions o3-timing-mp, simple-timing-mp and simple-atomic-mp (the latter are only used by SPARC at this point). The values chosen for the cache sizes match those that were used in the existing config scripts (despite being on the large side). Similarly, a mem_class parameter is added to the builder base class to enable simple-atomic to use SimpleMemory and o3-timing to use the default DDR3 configuration. Due to the different order the ports are connected, the bus stats get shuffled around for the multi-processor regressions. A separate patch bumps the port indices. Besides this, all behaviour is exactly the same.
2013-06-27config: Add a system clock command-line optionAkash Bagdia
This patch adds a 'sys_clock' command-line option and use it to assign clocks to the system during instantiation. As part of this change, the default clock in the System class is removed and whenever a system is instantiated a system clock value must be set. A default value is provided for the command-line option. The configs and tests are updated accordingly.
2013-06-27config: Remove redundant explicit setting of default clocksAkash Bagdia
This patch removes the explicit setting of the clock period for certain instances of CoherentBus, NonCoherentBus and IOCache where the specified clock is same as the default value of the system clock. As all the values used are the defaults, there are no performance changes. There are similar cases where the toL2Bus is set to use the parent CPU clock which is already the default behaviour. The main motivation for these simplifications is to ease the introduction of clock domains.
2013-06-27tests: Prune 00.gzip from the regressionsAndreas Hansson
This patch prunes the 00.gzip regressions with the main motivation being that it adds little (or no) coverage and requires a substantial amount of run time. A complete regression run, including compilation from a clean repo, is almost 20% faster(!).
2013-06-27scons: Identify runs that fail and runs with stats differencesAndreas Hansson
This patch changes the regression script such that it is possible to identify the runs that fail with an exit code, and those that finish with stats differences. The ones that truly fail are reported as FAILED, and those that finish with changed stats as CHANGED. The yellow colour has been reclaimed from the skipped regressions and is now used for the changed ones. With no obvious good option left the skipped ones are now in cyan. While I was editing the script I also bumped any occurence of M5 to gem5.

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

2013-04-22tests: 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.

2013-02-15config: 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().

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.
