If we fault, change the state to faulting so that we don't fault again in the same cycle.

2011-05-02scons: interpret paths relative to launch directorySteve Reinhardt
Make sure all command-line targets and EXTRAS directories are interpreted relative to the launch directory. This turns out to be very useful when building code from an EXTRAS directory using SCons's -C option. We were trying to do this with targets but it didn't actually work since we didn't update BUILD_TARGETS (so SCons got confused internally). We weren't even trying with EXTRAS. To simplify the code, the default target is also interpreted relative to the launch dir even though it was explicitly handled as relative to the m5 dir before... I doubt anyone really uses this anyway so it didn't seem worth the complexity. (Maybe we should get rid of it?)
2011-05-02scons: allow use of current builds as default build settingsSteve Reinhardt
Currently the --default= option only looks at the predefined build configs (in m5/build_opts), so you're limited to basing a new build config off of those (ALPHA_SE, etc.). If you've already defined a non-standard build config and want to clone it or tweak it, you have to start from scratch. This patch causes --default= to look first among the existing builds (in build/variables) before looking in build_opts so you can specify an existing non-standard build config as a starting point for a new config.

2011-04-29Util: Replace mkblankimage.sh with the new gem5img.py.Gabe Black
This change replaces the mkblankimage.sh script, used for creating new disk images, with a new gem5img.py script. The new version is written in python instead of bash, takes its parameters from command line arguments instead of prompting for them, and finds a free loopback device dynamically instead of hardcoding /dev/loop1. The file system used is now optionally configurable, and the blank image is filled by a "hole" left by lseek and write instead of literally filling it with zeroes. The functionality of the new script is broken into subcommands "init", "mount", "umount", "new", "partition", and "format". "init" creates a new file of the appropriate size, partitions it, and then formats the first (and only) new parition. "mount" attaches a new loopback device to the first parition of the image file and mounts it to the specified mount point. "umount" unmounts the specified mount point and identifies and cleans up the underlying loopback device. "new", "partition", and "format" are the individual stages of "init" but broken out so they can be run individually. That's so an image can be reinitialized in place if needed. Two features of the original script are being dropped. The first is the ability to specify a source directory to copy into the new file system. The second is the ability to specify a list of commands to run which are expected to (but not required to) update the permissions of the files in the new fs. Both of these seem easy enough to do manually, especially given the "mount" and "umount" commands, that removing them would meaningfully simplify the script without making it less useful.
2011-04-28regress: updates after changing ruby network bandwidthBrad Beckmann
2011-04-28network: set the ExtLink bw to 16 bytesBrad Beckmann
Therefore all links by default are 16 bytes wide and thus work with Garnet's uniform link bandwidth assumption.
2011-04-28garnet: removed flit_width from RoutersBrad Beckmann
2011-04-28network: adjusted default endpoint bandwidthBrad Beckmann
The simple network's endpoint bandwidth value is used to adjust the overall bandwidth of the network. Specifically, the ration between endpoint bandwidth and the MESSAGE_SIZE_MULTIPLIER determines the increase. By setting the value to 1000, that means the bandwdith factor specified in the links translates to the link bandwidth in bytes. Previously, it was increasing that value by 10. This patch will likely require a reset of the ruby regression tester stats.
2011-04-28network: removed the unused network-wide latency paramBrad Beckmann
2011-04-28network: moved network config paramsBrad Beckmann
Moved the buffer_size, endpoint_bandwidth, and adaptive_routing params out of the top-level parent network object and to only those networks that actually use those parameters.
2011-04-28network: basic link bw for garnet and simple networksBrad Beckmann
This patch ensures that both Garnet and the simple networks use the bw value specified in the topology. To do so, the patch generalizes the specification of bw for basic links. This value is then translated to the specific value used by the simple and Garnet networks. Since Garent does not support non-uniformed link bandwidth, the patch also adds a check to ensure all bws are equal. --HG-- rename : src/mem/ruby/network/BasicLink.cc => src/mem/ruby/network/simple/SimpleLink.cc rename : src/mem/ruby/network/BasicLink.hh => src/mem/ruby/network/simple/SimpleLink.hh rename : src/mem/ruby/network/BasicLink.py => src/mem/ruby/network/simple/SimpleLink.py
2011-04-28network: convert links & switches to first class C++ SimObjectsBrad Beckmann
This patch converts links and switches from second class simobjects that were virtually ignored by the networks (both simple and Garnet) to first class simobjects that directly correspond to c++ ojbects manipulated by the topology and network classes. This is especially true for Garnet, where the links and switches directly correspond to specific C++ objects. By making this change, many aspects of the Topology class were simplified. --HG-- rename : src/mem/ruby/network/Network.cc => src/mem/ruby/network/BasicLink.cc rename : src/mem/ruby/network/Network.hh => src/mem/ruby/network/BasicLink.hh rename : src/mem/ruby/network/Network.cc => src/mem/ruby/network/garnet/fixed-pipeline/GarnetLink_d.cc rename : src/mem/ruby/network/Network.hh => src/mem/ruby/network/garnet/fixed-pipeline/GarnetLink_d.hh rename : src/mem/ruby/network/garnet/fixed-pipeline/GarnetNetwork_d.py => src/mem/ruby/network/garnet/fixed-pipeline/GarnetLink_d.py rename : src/mem/ruby/network/garnet/fixed-pipeline/GarnetNetwork_d.py => src/mem/ruby/network/garnet/fixed-pipeline/GarnetRouter_d.py rename : src/mem/ruby/network/Network.cc => src/mem/ruby/network/garnet/flexible-pipeline/GarnetLink.cc rename : src/mem/ruby/network/Network.hh => src/mem/ruby/network/garnet/flexible-pipeline/GarnetLink.hh rename : src/mem/ruby/network/garnet/fixed-pipeline/GarnetNetwork_d.py => src/mem/ruby/network/garnet/flexible-pipeline/GarnetLink.py rename : src/mem/ruby/network/garnet/fixed-pipeline/GarnetNetwork_d.py => src/mem/ruby/network/garnet/flexible-pipeline/GarnetRouter.py

2011-04-28ruby: moved topology to the top network directoryBrad Beckmann
Moved the Topology class to the top network directory because it is shared by both the simple and Garnet networks. --HG-- rename : src/mem/ruby/network/simple/Topology.cc => src/mem/ruby/network/Topology.cc rename : src/mem/ruby/network/simple/Topology.hh => src/mem/ruby/network/Topology.hh

2011-04-25base: include types.hh in base/stats/mysql.hhNilay Vaish
Due to certain changes made via changeset 8229, the compilation was failing in certain cases. The compiler pointed to base/stats/mysql.hh for not naming a certain types like uint64_t. To rectify this, base/types.hh is being included in base/stats/mysql.hh.
2011-04-23X86: When decoding a memory only inst, fault on reg encodings, don't assert.Gabe Black
This change makes the decoder figure out if an instruction that only supports memory is using a register encoding and decodes directly to "Unknown" which will behave appropriately. This prevents other parts of the instruction creation process from seeing the mismatch and asserting.

2011-04-15scons: make a flexible system for guarding source filesNathan Binkert
This is similar to guards on mercurial queues and they're used for selecting which files are compiled into some given object. We already do something similar, but it's mostly hard coded for the m5 binary and the m5 library and I'd like to make it more flexible to better support the unittests
2011-04-15trace: reimplement the DTRACE function so it doesn't use a vectorNathan Binkert
At the same time, rename the trace flags to debug flags since they have broader usage than simply tracing. This means that --trace-flags is now --debug-flags and --trace-help is now --debug-help
