2016-04-06misc: Bail out of DVFS dot if we cannot resolve the domainsSascha Bischoff
This changeset updates the dot output to bail out if it is unable to resolve the voltage or clock domains (which will cause it to raise an AttributeError). Additionally, the DVFS dot output is disabled by default for speed purposes. Minor fixup for 0aeca8f.
2015-12-15misc: Add secondary dot output for DVFS domainsSascha Bischoff
This patch adds a secondary dot output file which shows the DVFS domains. This has been done separately for now to avoid cluttering the already existing diagram. Due to the way that the clock domains are assigned to components in gem5, this output must be generated after the C++ objects have been instantiated. This further motivates the need to generate this file separately to the current dot output, and not to replace it entirely.
2016-03-30style: Refactor the style checker as a Python packageAndreas Sandberg
Refactor the style checker into a Python module that can be reused by command line tools that integrate with git. In particular: * Create a style package in util * Move style validators from style.py to the style/validators.py. * Move style verifiers from style.py to the style/verifiers.py. * Move utility functions (sort_includes, region handling, file_types) into the style package * Move generic code from style.py to style/style.py.

2016-02-06style: remove trailing whitespaceSteve Reinhardt
Result of running 'hg m5style --skip-all --fix-white -a'.
2014-10-09config: Add Current as a parameter typeAndreas Hansson
This patch adds the Python parameter type Current, which is used for the DRAM power modelling (to start with). With this addition we avoid implicit unit assumptions.
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
2014-04-23misc: Proper type check and import for PortRefSascha Bischoff
Rewriting the type checking around PortRef, which was interacting strangely with other Python scripts. Tested-by: stephan.diestelhorst@arm.com
2013-09-04util: Add ini string as tooltip info in dot outputAndreas Hansson
This patch adds the config ini string as a tooltip that can be displayed in most browsers rendering the resulting svg. Certain characters are modified for HTML output. Tested on chrome and firefox.
2013-09-04util: Add colours to the dot outputAndreas Hansson
This patch is adding a splash of colour to the dot output to make it easier to distinguish objects of different types. As a bonus, the pastel-colour palette also makes the output look like a something from the 21st century.
2013-09-04util: Add class name to dot graph and output to svgAndreas Hansson
This patch adds the class name to the label, creates some more space by increasing the rank separation, and additionally outputs the graph as an editable SVG in addition to the PDF.
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.
2013-02-15base: Add warn() and inform() to m5.utils for use from pythonSascha Bischoff
This patch adds two fuctions to m5.util, warn and inform, which mirror those found in the C++ side of gem5. These are added in addition to the already existing m5.util.panic and m5.util.fatal which already mirror the C++ functionality. This ensures that warning and information messages generated by python are in the same format as those generated by C++. Occurrences of print "Warning: %s..." % name have been replaced with warn("%s...", name)
2012-05-10DOT: improved dot-based system visualizationUri Wiener
Revised system visualization to reflect structure and memory hierarchy. Improved visualization: less congested and cluttered; more colorful. Nodes reflect components; directed edges reflect dirctional relation, from a master port to a slave port. Requires pydot.
2012-04-14Regression: Add ANSI colours to highlight test statusAndreas Hansson
This patch adds a very basic pretty-printing of the test status (passed or failed) to highlight failing tests even more: green for passed, and red for failed. The printing only uses ANSI it the target output is a tty and supports ANSI colours. Hence, any regression scripts that are outputting to files or sending e-mails etc should still be fine.

2011-07-05grammar: better encapsulation of a grammar and parsingNathan Binkert
This makes it possible to use the grammar multiple times and use the multiple instances concurrently. This makes implementing an include statement as part of a grammar possible.
2011-05-29Misc: Remove the URL from warnings, fatals, panics, etc.Gabe Black
2011-04-15region: add a utility class for keeping track of regions of some rangeNathan Binkert
This is basically like the range_map stuff in src/base (range already exists in Python). This code is like a set of ranges. I'm using it to keep track of changed lines in source code, but it could be use to keep track of memory ranges and holes in memory regions. It could also be used in memory allocation type stuff. (Though it's not at all optimized.)
2011-04-15SortedDict: add functions for getting ranges of keys, values, itemsNathan Binkert
2011-01-07scons: show sources and targets when building, and colorize output.Steve Reinhardt
I like the brevity of Ali's recent change, but the ambiguity of sometimes showing the source and sometimes the target is a little confusing. This patch makes scons typically list all sources and all targets for each action, with the common path prefix factored out for brevity. It's a little more verbose now but also more informative. Somehow Ali talked me into adding colors too, which is a whole 'nother story.
2010-11-23Copyright: Add AMD copyright to the param changes I just made.Gabe Black
2010-11-23Params: Add parameter types for IP addresses in various forms.Gabe Black
New parameter forms are: IP address in the format "a.b.c.d" where a-d are from decimal 0 to 255. IP address with netmask which is an IP followed by "/n" where n is a netmask length in bits from decimal 0 to 32 or by "/e.f.g.h" where e-h are from decimal 0 to 255 and which is all 1 bits followed by all 0 bits when represented in binary. These can also be specified as an integral IP and netmask passed in separately. IP address with port which is an IP followed by ":p" where p is a port index from decimal 0 to 65535. These can also be specified as an integral IP and port value passed in separately.

2010-07-21python: add a sorted dictionary classNathan Binkert
It would be nice if python had a tree class that would do this for real, but since we don't, we'll just keep a sorted list of keys and update it on demand.

2008-06-14python: Move various utility classes into a new m5.util package soNathan Binkert
