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.

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.
