2013-05-30util: Auto generate the packet proto definitionsAndreas Hansson
This patch simplifies the usage of the packet trace encoder/decoder by attempting to automatically generating the packet proto definitions in case they cannot be found.
2013-05-14arm: Add support for the m5fail pseudo-opAndreas Sandberg
2013-05-14arm: Fix compilation error in m5 utilityAndreas Sandberg
Changeset 5ca6098b9560 accidentally broke the m5 utility. This changeset adds the missing co-processor call used to trigger the pseudo-op in ARM mode and fixes an alignment issue that caused some pseudo-ops to leave thumb mode.
2013-05-07arm: Make libm5 a dependency of the m5 utilityAndreas Sandberg
The m5 utility wasn't relinked properly since libm5.a wasn't a dependency of the utility. This changeset addresses that issue.
2013-04-22kvm: Add support for pseudo-ops on ARMAndreas Sandberg
This changeset adds support for m5 pseudo-ops when running in kvm-mode. Unfortunately, we can't trap the normal gem5 co-processor entry in KVM (it doesn't seem to be possible to trap accesses to non-existing co-processors). We therefore use BZJ instructions to cause a trap from virtualized mode into gem5. The BZJ instruction is becomes a normal branch to the gem5 fallback code when running in simulated mode, which means that this patch does not need to change the ARM ISA-specific code. Note: This requires a patched host kernel.
2013-03-26util: Add a utility script for decoding packet tracesAndreas Hansson
This patch adds a simple Python script that reads the protobuf-encoded packet traces (not gzipped), and prints them to an ASCII trace file. The script can also be used as a template for other packet output formats.
2013-03-26util: Add a utility script for encoding packet tracesAndreas Hansson
This patch adds a simple Python script that reads a simple ASCII trace format and encodes it as protobuf output compatible with the traffic generator. The script can also be used as a template for other packet input formats that should be converted to the gem5 packet protobuf format.
2013-03-25x86: Revert [02321b16685f] which breaks m5ops on x86Andreas Sandberg
Changeset 02321b16685f added m5_writefile to m5op_x86.S a second time, which causes a compilation error on when compiling for x86. This changeset reverts that changeset and fixes the error.
2013-02-15o3: fix tick used for renaming and issue with range selectionMatt Horsnell
Fixes the tick used from rename: - previously this gathered the tick on leaving rename which was always 1 less than the dispatch. This conflated the decode ticks when back pressure built in the pipeline. - now picks up tick on entry. Added --store_completions flag: - will additionally display the store completion tail in the viewer. - this highlights periods when large numbers of stores are outstanding (>16 LSQ blocking) Allows selection by tick range (previously this caused an infinite loop)
2013-01-08util: add writefile to m5 util program for x86Lluís Vilanova
2013-01-08util: add m5_fail op.Lluís Vilanova
Used as a command in full-system scripts helps the user ensure the benchmarks have finished successfully. For example, one can use: /path/to/benchmark args || /sbin/m5 fail 1 and thus ensure gem5 will exit with an error if the benchmark fails.
2013-01-07util: Fix stack corruption in the m5 utilAndreas Sandberg
The number of arguments specified when calling parse_int_args() in do_exit() is incorrect. This leads to stack corruption since it causes writes past the end of the ints array.
2013-01-07arm: Remove the register mapping hack used when copying TCsAndreas Sandberg
In order to see all registers independent of the current CPU mode, the ARM architecture model uses the magic MISCREG_CPSR_MODE register to change the register mappings without actually updating the CPU mode. This hack is no longer needed since the thread context now provides a flat interface to the register file. This patch replaces the CPSR_MODE hack with the flat register interface.
2013-01-07arch: Move the ISA object to a separate sectionAndreas Sandberg
After making the ISA an independent SimObject, it is serialized automatically by the Python world. Previously, this just resulted in an empty ISA section. This patch moves the contents of the ISA to that section and removes the explicit ISA serialization from the thread contexts, which makes it behave like a normal SimObject during serialization. Note: This patch breaks checkpoint backwards compatibility! Use the cpt_upgrader.py utility to upgrade old checkpoints to the new format.

2012-10-09m5: Expose m5 pseudo-instructions to C/C++ via a static libraryJames Clarkson
Updated the util/m5/Makefile.arm so that m5op_arm.S is used to create a static library - libm5.a. Allowing users to insert m5 psuedo-instructions into their applications for fine-grained checkpointing, switching cpus or dumping statistics. e.g. #include <m5op.h> void foo(){ ... m5_reset_stats(<delay>,<period>) m5_work_begin(<workid>,<threadid>); ... m5_work_end(<workid>,<threadid>); m5_dump_stats(<delay>,<period>); }
2012-11-02ARM: dump stats and process info on context switchesDam Sunwoo
This patch enables dumping statistics and Linux process information on context switch boundaries (__switch_to() calls) that are used for Streamline integration (a graphical statistics viewer from ARM).
2012-10-15Mem: Separate the host and guest views of memory backing storeAndreas Hansson
This patch moves all the memory backing store operations from the independent memory controllers to the global physical memory. The main reason for this patch is to allow address striping in a future set of patches, but at this point it already provides some useful functionality in that it is now possible to change the number of memory controllers and their address mapping in combination with checkpointing. Thus, the host and guest view of the memory backing store are now completely separate. With this patch, the individual memory controllers are far simpler as all responsibility for serializing/unserializing is moved to the physical memory. Currently, the functionality is more or less moved from AbstractMemory to PhysicalMemory without any major changes. However, in a future patch the physical memory will also resolve any ranges that are interleaved and properly assign the backing store to the memory controllers, and keep the host memory as a single contigous chunk per address range. Functionality for future extensions which involve CPU virtualization also enable the host to get pointers to the backing store.
2012-09-25Util: Added script to semantically diff two config.ini filesSascha Bischoff
This script (util/diff_config.pl) takes two config.ini files and compares them. It highlights value changes, as well as displaying which parts are unique to a specific config.ini file. This is useful when trying to replicate an earlier experiment and when trying to make small changes to an existing configuration.

2012-02-05Regressions: Fix the regress script when "all" is used.Gabe Black
When the "all" test is specified, the "tests" list should have two elements in it, "quick" and "long", not a single element "quick,long". The later would be appropriate as the default for one of the command line options which are split at commas, but at that point "tests" should already be a list.
2012-02-02Regression: Update the regress script after SE/FS mergeAndreas Hansson
This patch updates the regress script to reflect the merge of the SE/FS builds and the new structure of the test directories. It adds a "mode" flag to the script, that defaults to both se and fs.
2012-01-31util: implements "writefile" gem5 op to export file from guest to host ↵Dam Sunwoo
filesystem Usage: m5 writefile <filename> File will be created in the gem5 output folder with the identical filename. Implementation is largely based on the existing "readfile" functionality. Currently does not support exporting of folders.

2011-09-13gem5ops: Implement Java JNI for gem5OpsPrakash Ramrakhyani
These ops allow gem5 ops to be called from within java programs like the following: import jni.gem5Op; public class HelloWorld { public static void main(String[] args) { gem5Op gem5 = new gem5Op(); System.out.println("Rpns0:" + gem5.rpns()); System.out.println("Rpns1:" + gem5.rpns()); } static { System.loadLibrary("gem5OpJni"); } } When building you need to make sure classpath include gem5OpJni.jar: javac -classpath $CLASSPATH:/path/to/gem5OpJni.jar HelloWorld.java and when running you need to make sure both the java and library path are set: java -classpath $CLASSPATH:/path/to/gem5OpJni.jar -Djava.library.path=/path/to/libgem5OpJni.so HelloWorld

2011-05-24style: Make the style hook work in directories other than the root.Nathan Binkert
2011-05-23util/regress: make default action a more thorough regressionSteve Reinhardt
Changed the --variants option to --test-variants and added a new --compile-variants option for variants that are only compiled (not tested). The former still defaults to 'opt' and the latter defaults to 'debug,fast'. Also changed the behavior when no tests are specified from just compiling to running the 'quick' tests. As a result, a plain 'util/regress' invocation will now compile (but not test) the debug and fast builds, and compile and run the quick regressions on the opt build. This should be the default set of tests that are run before committing. Since the nightly regressions use this same script, this will also be the new nightly regression behavior. Test-only regressions can still be done by setting --compile=''. Compile-only regressions can be done by setting --test=''.
2011-05-04ARM: Add vfpv3 support to native trace.Ali Saidi
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.
