GXemul is a framework for full-system computer architecture emulation.
Several processor architectures and machine types have been implemented.
It is working well enough to allow unmodified
"guest" operating systems to run inside the emulator,
as if they were running on real hardware.
The emulator emulates (networks of) real machines. The machines may consist of ARM, MIPS, Motorola 88K, PowerPC, and SuperH processors, and various surrounding hardware components such as framebuffers, busses, interrupt controllers, ethernet controllers, disk controllers, and serial port controllers.
The documentation lists the machines and guest operating systems that can be regarded as "working" in GXemul. The best working guest operating systems are NetBSD/pmax and NetBSD/cats.
The changes between release 0.4.6.6 and 0.4.7 are:
A big thank you goes to Miod Vallat, who sent me physical 88100 documentation, via snail mail. This has been invaluable when implementing the 88K emulation mode.
The changes between release 0.4.7 and 0.4.7.1 are:
The changes between release 0.4.7.1 and 0.4.7.2 are:
Please read the HISTORY file for more details.
Files included in this release are:
HISTORY Detailed revision history / changelog.
LICENSE Copyright message / license.
README Quick start instructions, for the impatient.
RELEASE.html This file.
TODO TODO notes.
configure, Makefile.skel sh and make scripts for building GXemul.
demos/ Tutorial-like demos of testmachine functionality.
doc/ Documentation.
experiments/ Experimental code. (Usually not needed.)
man/ Man page.
src/ Source code.
To build the emulator, run the configure script, and then run make. This should work on most Unix-like systems, with few or no modifications to the source code.
Regarding files in the src/include/ directory: only some of these are written by me, the rest are from other sources (such as NetBSD). The license text says that "All advertising materials mentioning features or use of this software" must display acknowledgements. Even though I do not feel that I mention features or use of the header files (the "software") in any advertising materials, I am still very grateful for the fact that these people have made their files available for re-use, as Free software, so regardless of legal requirements, I guess thanking them like this is in order:
