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.
2012-01-17MEM: Add port proxies instead of non-structural portsAndreas Hansson
Port proxies are used to replace non-structural ports, and thus enable all ports in the system to correspond to a structural entity. This has the advantage of accessing memory through the normal memory subsystem and thus allowing any constellation of distributed memories, address maps, etc. Most accesses are done through the "system port" that is used for loading binaries, debugging etc. For the entities that belong to the CPU, e.g. threads and thread contexts, they wrap the CPU data port in a port proxy. The following replacements are made: FunctionalPort > PortProxy TranslatingPort > SETranslatingPortProxy VirtualPort > FSTranslatingPortProxy --HG-- rename : src/mem/vport.cc => src/mem/fs_translating_port_proxy.cc rename : src/mem/vport.hh => src/mem/fs_translating_port_proxy.hh rename : src/mem/translating_port.cc => src/mem/se_translating_port_proxy.cc rename : src/mem/translating_port.hh => src/mem/se_translating_port_proxy.hh
2012-01-16Alpha: warn_once about broken PAL breakpoints.Steve Reinhardt
A recent changeset (aae12ce9f34c) removed support for PAL-mode breakpoints in Alpha, since it was awkward and likely unused. This patch lets a user know if they potentially run into this limitation.
2012-01-16debug: fix AllFlags::disable()Steve Reinhardt
Looks like copy-and-paste bug, apparently I'm the first person to ever use this since it's plainly broken.
2012-01-09stats: fix Vector2d to display stats correctly when y_subname is not specified.Dam Sunwoo
Vector2d stats with no y_subname were not displayed as the VectorPrint subname was not initialized correctly to reflect the empty field.
2012-01-09sim: Enable sampling of run-time for code-sections marked using pseudo insts.Prakash Ramrakhyani
This patch adds a mechanism to collect run time samples for specific portions of a benchmark, using work_begin and work_end pseudo instructions.It also enhances the histogram stat to report geometric mean.
2012-01-09Base: Fixed shift amount in genrand() to work with large numbersDam Sunwoo
The previous version didn't work correctly with max integer values (2^31-1 for 32-bit, 2^63-1 for 64bit version), causing "shift" to become -1. For smaller numbers, it wouldn't have caused functional errors, but would have resulted in more than necessary loops in the while loop. Special-cased cases when (max + 1 == 0) to prevent the ceilLog2 functions from failing.
2012-01-09MAC: Make gem5 compile and run on MacOSX 10.7.2Andreas Hansson
Adaptations to make gem5 compile and run on OSX 10.7.2, with a stock gcc 4.2.1 and the remaining dependencies from macports, i.e. python 2.7,.2 swig 2.0.4, mercurial 2.0. The changes include an adaptation of the SConstruct to handle non-library linker flags, and Darwin-specific code to find the memory usage of gem5. A number of Ruby files relied on ambigious uint (without the 32 suffix) which caused compilation errors.

2011-12-01VNC: Add support for capturing frame buffer to file each time it is changed.Chris Emmons
When a change in the frame buffer from the VNC server is detected, the new frame is stored out to the m5out/frames_*/ directory. Specifiy the flag "--frame-capture" when running configs/example/fs.py to enable this behavior. --HG-- extra : rebase_source : d4e08e83f4fa6ff79f3dc9c433fc1f0487e057fc

And by "everything" I mean all the quick regressions.
2011-08-19Stats: Add a sparse histogram stat object.Thomas Grass
2011-06-12Loader: Handle bad section names when loading an ELF file.Gabe Black
If there's a problem when reading the section names from a supposed ELF file, this change makes gem5 print an error message as returned by libelf and die. Previously these sorts of errors would make gem5 segfault when it tried to access the section name through a NULL pointer.

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.
2011-04-20stats: ensure that stat names are validNathan Binkert
2011-04-20stats: add user settable separator string for arrayed statsBrad Danofsky
Default is '::', so no visible change unless it is overridden
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

2011-03-18base: disable FastAlloc in debug builds by defaultSteve Reinhardt
FastAlloc's reuse policies can mask allocation bugs, so we typically want it disabled when debugging. Set FORCE_FAST_ALLOC to enable even when debugging, and set NO_FAST_ALLOC to disable even in non-debug builds.

2011-01-15time: improve time datastructureNathan Binkert
Use posix clock functions (and librt) if it is available. Inline a bunch of functions and implement more operators. * * * time: more cleanup

2011-01-10Curtick: Fix mysql.cc build needing curTick.Gabe Black
2011-01-07Replace curTick global variable with accessor functions.Steve Reinhardt
This step makes it easy to replace the accessor functions (which still access a global variable) with ones that access per-thread curTick values.
2011-01-04Params: Print the IP components in the right order.Gabe Black
2011-01-03Move sched_list.hh and timebuf.hh from src/base to src/cpu.Steve Reinhardt
These files really aren't general enough to belong in src/base. This patch doesn't reorder include lines, leaving them unsorted in many cases, but Nate's magic script will fix that up shortly. --HG-- rename : src/base/sched_list.hh => src/cpu/sched_list.hh rename : src/base/timebuf.hh => src/cpu/timebuf.hh
2011-01-03Delete unused files from src/base directory.Steve Reinhardt
2011-01-03Make commenting on close namespace brackets consistent.Steve Reinhardt
Ran all the source files through 'perl -pi' with this script: s|\s*(};?\s*)?/\*\s*(end\s*)?namespace\s*(\S+)\s*\*/(\s*})?|} // namespace $3|; s|\s*};?\s*//\s*(end\s*)?namespace\s*(\S+)\s*|} // namespace $2\n|; s|\s*};?\s*//\s*(\S+)\s*namespace\s*|} // namespace $1\n|; Also did a little manual editing on some of the arch/*/isa_traits.hh files and src/SConscript.
2011-01-03RefCount: Fix reference counting pointer == and != with a T* on the left.Gabe Black
These operators were expecting a const T& instead of a const T*, and were not being picked up and used by gcc in the right places as a result. Apparently no one used these operators before. A unit test which exposed these problems, verified the solution, and checks other basic functionality is on the way.
2010-12-21Get rid of unused file src/base/dbl_list.hhSteve Reinhardt
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.
