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. |

This is the M5 simulator. For detailed information about building the simulator and getting started please refer to http://www.m5sim.org. Specific pages of interest are: http://www.m5sim.org/wiki/index.php/Compiling_M5 http://www.m5sim.org/wiki/index.php/Running_M5 Short version: 1. If you don't have SCons version 0.98.1 or newer, get it from http://wwww.scons.org. 2. If you don't have SWIG version 1.3.31 or newer, get it from http://wwww.swig.org. 3. Make sure you also have gcc version 3.4.6 or newer, Python 2.4 or newer (the dev version with header files), zlib, and the m4 preprocessor. 4. In this directory, type 'scons build/ALPHA_SE/tests/debug/quick'. This will build the debug version of the m5 binary (m5.debug) for the Alpha syscall emulation target, and run the quick regression tests on it. If you have questions, please send mail to m5-users@m5sim.org WHAT'S INCLUDED (AND NOT) ------------------------- The basic source release includes these subdirectories: - m5: - configs: simulation configuration scripts - ext: less-common external packages needed to build m5 - src: source code of the m5 simulator - system: source for some optional system software for simulated systems - tests: regression tests - util: useful utility programs and files To run full-system simulations, you will need compiled system firmware (console and PALcode for Alpha), kernel binaries and one or more disk images. These files for Alpha are collected in a separate archive, m5_system.tar.bz2. This file can he downloaded separately. Depending on the ISA used, M5 may support Linux 2.4/2.6, FreeBSD, and the proprietary Compaq/HP Tru64 version of Unix. We are able to distribute Linux and FreeBSD bootdisks, but we are unable to distribute bootable disk images of Tru64 Unix. If you have a Tru64 license and are interested in obtaining disk images, contact us at m5-users@m5sim.org
