GXemul is an experimental instruction-level machine emulator. Several |
8 |
|
|
emulation modes are available. In some modes, processors and surrounding |
9 |
dpavlin |
12 |
hardware components are emulated well enough to let unmodified operating |
10 |
|
|
systems (e.g. NetBSD) run as if they were running on a real machine. |

The documentation lists the machines and guest operating systems that can |
13 |
|
|
be regarded as "working" in GXemul. The best supported guest operating |
14 |
|
|
systems are probably NetBSD/pmax, NetBSD/cats, and OpenBSD/cats. |

The user-visible changes between release 0.3.7 and 0.3.8 include: |
17 |

|
18 |
dpavlin |
22 |
o) The IQ80321 (Xscale) machine mode is now working well enough to |
19 |
|
|
run NetBSD/evbarm 2.1. |

|
21 |

22 |
o) Faster framebuffer output in some situations. |

Source code related changes include: |

10 |
|
25 |
dpavlin |
22 |
o) I've finally begun to reimplement the MIPS emulation mode using the |
26 |
|
|
new dyntrans system. It will be quite some time until it can run |
27 |
|
|
anything, but things are moving in the right direction. |
28 |
dpavlin |

|
29 |
dpavlin |
22 |
o) Some changes to the concepts of input-only, output-only, and |
30 |
|
|
input-output consoles. |
31 |
dpavlin |

|
32 |
dpavlin |
22 |
o) Some more clean-up of PCI bus concepts. |
33 |
dpavlin |

|
34 |
dpavlin |
22 |
o) Machine definitions have been moved out of src/machines.c, and into |
35 |
|
|
individual files in a new sub-directory (src/machines/). |

There have also been lots of other changes, too many and small to mention here. |

To build the emulator, run the ./configure script, and then run make. This |
53 |
|
|
should work on most Unix-like systems. |

Regarding files in the src/include/ directory: only some of these are written |
56 |
|
|
by me, the rest are from other sources (such as NetBSD). The license text says |
57 |
dpavlin |
2 |
that "All advertising materials mentioning features or use of this software" |
58 |
|
|
must display acknowledgements. Even though I do NOT feel I mention features or |
59 |
|
|
use of the header files (the "software") in any advertising materials, I am |
60 |
|
|
still very grateful for the fact that these people have made their files |
61 |
|
|
available for re-use, so regardless of legal requirements, I guess thanking |
62 |
|
|
them like this is in order: |
