2014-09-20mem: Rename Bus to XBar to better reflect its behaviourAndreas Hansson
This patch changes the name of the Bus classes to XBar to better reflect the actual timing behaviour. The actual instances in the config scripts are not renamed, and remain as e.g. iobus or membus. As part of this renaming, the code has also been clean up slightly, making use of range-based for loops and tidying up some comments. The only changes outside the bus/crossbar code is due to the delay variables in the packet. --HG-- rename : src/mem/Bus.py => src/mem/XBar.py rename : src/mem/coherent_bus.cc => src/mem/coherent_xbar.cc rename : src/mem/coherent_bus.hh => src/mem/coherent_xbar.hh rename : src/mem/noncoherent_bus.cc => src/mem/noncoherent_xbar.cc rename : src/mem/noncoherent_bus.hh => src/mem/noncoherent_xbar.hh rename : src/mem/bus.cc => src/mem/xbar.cc rename : src/mem/bus.hh => src/mem/xbar.hh
2014-09-20tests: Add a memtest version using the ideal SnoopFilterAndreas Hansson
This patch adds a basic regression test for the snoop filter. --HG-- rename : tests/configs/memtest.py => tests/configs/memtest-filter.py
2014-08-25tests: automatically kill regressions that take too longCurtis Dunham
When GNU coreutils 'timeout' is available, limit each regression simulation to 4 hours.
2014-09-12stats: Minor update of Minor stats after uncacheable fixAndreas Hansson
2014-09-03stats: Update stats for CPU and cache changesAndreas Hansson
This patch updates the stats to reflect the fixes and changes to the CPU (mainly the o3), and the caches.
2014-09-03tests: Use medium dataset for perlbmk regressionsAndreas Hansson
This patch changes the perlbmk regression script from the large to the medium dataset to reduce the regression run time. For all ISAs and CPU models, the total perlbmk host CPU time with the large dataset is roughly 12 hours (constituting >30% of the total regression host time). There is, most likely, almost no added value in terms of code coverage for this rather excessive run time.
2014-09-03alpha: Stop using 'inorder' and rely entirely on 'minor'Andreas Hansson
This patch avoids building the 'inorder' CPU model for any permutation of ALPHA, and also removes the ALPHA regressions using the 'inorder' CPU. The 'minor' CPU is already providing a broader test coverage.
2014-09-03tests: Use O3_ARM_v7a config for full-system ARM regressionsAndreas Hansson
This patch changes the CPU configuration used for the full-system ARM regressions to increase the test coverage. Note that it is only the core configuration, and not the caches etc.

Also updates many out of date config files.
2014-09-01ruby: Fixes clock domains in configuration filesEmilio Castillo ext:(%2C%20Nilay%20Vaish%20%3Cnilay%40cs.wisc.edu%3E)
This patch fixes scripts related to ruby by adding the ruby clock domain. Now the L1 controllers and the Sequencer shares the cpu clock domain, while the rest of the components use the ruby clock domain. Before this patch, running simulations with the cpu clock set at 2GHz or 1GHz will output the same time results and could distort power measurements. Committed by: Nilay Vaish <nilay@cs.wisc.edu>
2014-07-28stats: Bump stats for the regressions using the minor CPUAndreas Hansson
Updating the stats to match the current behaviour.
2014-07-23cpu: Minor CPU add regression tests for ARM and ALPHAAndrew Bardsley
This patch adds regression tests results and test harnesses for the Minor CPU on ARM and ALPHA.
2014-07-19stats: update for syscall DPRINTF changeSteve Reinhardt
Only printing one rather than two args for the ignored syscall warning means the count of register accesses has changed on a few runs. Oddly only Alpha Tru64 seems to have any ignored syscalls in the regression tests.
2014-06-22stats: update for O3 changesSteve Reinhardt
Mostly small differences in total ticks, but O3 stall causes shifted significantly. 30.eon does speed up by ~6% on Alpha and ARM, and 50.vortex by 4.5% on ARM. At the other extreme, X86 70.twolf is 0.8% slower.

2014-05-09tests: Reflect name change in DRAM testsAndreas Hansson
This patch reflects the recent name change in the DRAM TrafficGen tests and also tidies up the test directory. --HG-- rename : tests/configs/tgen-simple-dram.py => tests/configs/tgen-dram-ctrl.py rename : tests/quick/se/70.tgen/ref/null/none/tgen-simple-dram/config.ini => tests/quick/se/70.tgen/ref/null/none/tgen-dram-ctrl/config.ini rename : tests/quick/se/70.tgen/ref/null/none/tgen-simple-dram/simerr => tests/quick/se/70.tgen/ref/null/none/tgen-dram-ctrl/simerr rename : tests/quick/se/70.tgen/ref/null/none/tgen-simple-dram/simout => tests/quick/se/70.tgen/ref/null/none/tgen-dram-ctrl/simout rename : tests/quick/se/70.tgen/ref/null/none/tgen-simple-dram/stats.txt => tests/quick/se/70.tgen/ref/null/none/tgen-dram-ctrl/stats.txt rename : tests/quick/se/70.tgen/tgen-simple-dram.cfg => tests/quick/se/70.tgen/tgen-dram-ctrl.cfg
2014-05-09arch: teach ISA parser how to split code across filesCurtis Dunham
This patch encompasses several interrelated and interdependent changes to the ISA generation step. The end goal is to reduce the size of the generated compilation units for instruction execution and decoding so that batch compilation can proceed with all CPUs active without exhausting physical memory. The ISA parser (src/arch/isa_parser.py) has been improved so that it can accept 'split [output_type];' directives at the top level of the grammar and 'split(output_type)' python calls within 'exec {{ ... }}' blocks. This has the effect of "splitting" the files into smaller compilation units. I use air-quotes around "splitting" because the files themselves are not split, but preprocessing directives are inserted to have the same effect. Architecturally, the ISA parser has had some changes in how it works. In general, it emits code sooner. It doesn't generate per-CPU files, and instead defers to the C preprocessor to create the duplicate copies for each CPU type. Likewise there are more files emitted and the C preprocessor does more substitution that used to be done by the ISA parser. Finally, the build system (SCons) needs to be able to cope with a dynamic list of source files coming out of the ISA parser. The changes to the SCons{cript,truct} files support this. In broad strokes, the targets requested on the command line are hidden from SCons until all the build dependencies are determined, otherwise it would try, realize it can't reach the goal, and terminate in failure. Since build steps (i.e. running the ISA parser) must be taken to determine the file list, several new build stages have been inserted at the very start of the build. First, the build dependencies from the ISA parser will be emitted to arch/$ISA/generated/inc.d, which is then read by a new SCons builder to finalize the dependencies. (Once inc.d exists, the ISA parser will not need to be run to complete this step.) Once the dependencies are known, the 'Environments' are made by the makeEnv() function. This function used to be called before the build began but now happens during the build. It is easy to see that this step is quite slow; this is a known issue and it's important to realize that it was already slow, but there was no obvious cause to attribute it to since nothing was displayed to the terminal. Since new steps that used to be performed serially are now in a potentially-parallel build phase, the pathname handling in the SCons scripts has been tightened up to deal with chdir() race conditions. In general, pathnames are computed earlier and more likely to be stored, passed around, and processed as absolute paths rather than relative paths. In the end, some of these issues had to be fixed by inserting serializing dependencies in the build. Minor note: For the null ISA, we just provide a dummy inc.d so SCons is never compelled to try to generate it. While it seems slightly wrong to have anything in src/arch/*/generated (i.e. a non-generated 'generated' file), it's by far the simplest solution.
2014-05-09mem: Auto-generate CommMonitor trace file namesSascha Bischoff
Splits the CommMonitor trace_file parameter into three parameters. Previously, the trace was only enabled if the trace_file parameter was set, and would be written to this file. This patch adds in a trace_enable and trace_compress parameter to the CommMonitor. No trace is generated if trace_enable is set to False. If it is set to True, the trace is written to a file based on the name of the SimObject in the simulation hierarchy. For example, system.cluster.il1_commmonitor.trc. This filename can be overridden by additionally specifying a file name to the trace_file parameter (more on this later). The trace_compress parameter will append .gz to any filename if set to True. This enables compression of the generated traces. If the file name already ends in .gz, then no changes are made. The trace_file parameter will override the name set by the trace_enable parameter. In the case that the specified name does not end in .gz but trace_compress is set to true, .gz is appended to the supplied file name.

This patch updates the stats to reflect the changes to the DRAM controller.
2014-03-20stats: updates due to changes to ruby config scriptsNilay Vaish
These updates to ruby regression stats are due to renaming piobus to iobus and dropping piobus in the se mode.
2014-03-20config: ruby: rename _cpu_ruby_ports to _cpu_portsNilay Vaish
2014-03-20config: remove ruby_fs.pyNilay Vaish
The patch removes the ruby_fs.py file. The functionality is being moved to fs.py. This would being ruby fs simulations in line with how ruby se simulations are started (using --ruby option). The alpha fs config functions are being combined for classing and ruby memory systems. This required renaming the piobus in ruby to iobus. So, we will have stats being renamed in the stats file for ruby fs regression.
2014-03-20ruby: no piobus in se modeNilay Vaish
Piobus was recently added to se scripts for ruby so that the interrupt controller can be connected to something (required since the interrupt controller sends address range messages). This patch removes the piobus and instead, the pio port of ruby port will now ignore the range change messages in se mode.

2014-02-24ruby: correct errors in changeset 4eec7bdde5b0Nilay Vaish
Couple of errors were discovered in 4eec7bdde5b0 which necessitated this patch. Firstly, we create interrupt controllers in the se mode, but no piobus was being created. RubyPort, which earlier used to ignore range changes now forwards those to the piobus. The lack of piobus resulted in segmentation fault. This patch creates a piobus even in se mode. It is not created only when some tester is running. Secondly, I had missed out on modifying port connections for other coherence protocols.

2014-02-23ruby: route all packets through ruby portNilay Vaish
Currently, the interrupt controller in x86 is connected to the io bus directly. Therefore the packets between the io devices and the interrupt controller do not go through ruby. This patch changes ruby port so that these packets arrive at the ruby port first, which then routes them to their destination. Note that the patch does not make these packets go through the ruby network. That would happen in a subsequent patch.

2014-01-03config, x86: move kernel specification from tests to FSConfig.pySteve Reinhardt
For some reason, the default x86 kernel is specified in tests/configs/x86_generic.py and not in configs/common/FSConfig.py, where the kernels for all the other ISAs are. This means that running configs/example/fs.py for x86 fails because no kernel is specified. Moving the specification over fixes this problem. There is another problem that this uncovers, which is that going past the init stage (i.e., past where the regression test stops) fails because the fsck test on the disk device fails, but that's a separate issue.

2013-11-14tests: suppress output on switcheroo testsSteve Reinhardt
The output from the switcheroo tests is voluminous and (because it includes timestamps) highly sensitive to minor changes, leading to extremely large updates to the reference outputs. This patch addresses this problem by suppressing output from the tests. An internal parameter can be set to enable the output. Wiring that up to a command-line flag (perhaps even the rudimantary -v/-q options in m5/main.py) is left for future work.

2013-10-16test: update statsSteve Reinhardt
Update stats for recent changes. Mostly minor changes in register access stats due to addition of new cc register type and slightly different (and more accurate) classification of int vs. fp register accesses.
2013-10-15scons: fix minor update-ref bug in regressionsSteve Reinhardt
In the unusual case that regressions are run with --update-ref when there is no existing regression output, scons gets confused because it depends on stats.txt to trigger the update, but it has no indication that running the test will generate the stats.txt file. (In the typical case where stats.txt already exists, scons doesn't care about where it came from.) It's easy to fix this just by adding the stats.txt file to the target list for the test action.
