Introduction

+ +

The FreeBSD/ppc project pages contain information about the FreeBSD + port to the PowerPC® architecture. As with the port itself, these + pages are still a work in progress.

+ +

The FreeBSD/ppc port is still a Tier-2 platform. That means it is + not being fully supported by our security officer, release engineers and + toolchain maintainers.

What is the FreeBSD/PowerPC project?

How can I install FreeBSD/ppc?

FreeBSD/PowerPC is a port of the FreeBSD operating system - to computers with the PowerPC processor, most notably - recent Macintosh® computers.

FreeBSD/ppc is in HEAD branch of the FreeBSD CVS repository. However + there is an ISO image available for download + here. + Please follow instructions given + here.

What hardware are you targeting?

Where can I find packages for FreeBSD/ppc?

At the moment "New World" (i.e. colourful case) - Apple Macintoshes. Other platforms, such as older - Power Mac®s and non-Apple computers using Open Firmware, - are expected to be targeted later on.

Courtesy of Peter Grehan and Tilman Linneweh, you can find some packages + here and + here. -

Who should I contact?

FreeBSD/PowerPC currently is on the verge of booting - to single-user mode.

Peter Grehan is the project + lead. Contact him if you can contribute code. If you just want + to know about the status of this project, check this page + regularly or join the + FreeBSD/ppc mailing list.

How can I acquire FreeBSD/PowerPC?

FreeBSD/PowerPC is mostly in cvs for -CURRENT.

Supported Hardware

+ +

The FreeBSD/ppc port should run on any New-World machine. People + reported FreeBSD runs on following machines:

Known Issues

FreeBSD/PowerPC mailing list

On-board BMAC+ ethernet does not work. There is a work-in-progress + bm(4) driver available on Peter Grehan's personal page + here (see if_bm.c and + if_bmreg.h).
There is no graphical mouse cursor on console.
Fdisk does not work.
Only USB keyboards are supported.
If you have Bluetooth, there is a 'fake' OHCI port and devices + created that can be used to access a wireless keyboard or mouse. + Problem is, it gets probed before the fixed keyboard/mouse and is + first in line to syscons. To get around this, the PCI slot associated + with the problematic ohci2 can be disabled at the loader prompt: +
```
OK set hint.pcib.1.skipslot=26
```
For ATI Radeon-based machines: +
- A ofw syscons range check needs to be relaxed using the sysctl + hw.ofwfb.relax_mmap.
- A special radeon + driver + is needed. You must add the following your xorg.conf into the + Section "Device":
```
Option "iBookHacks" "on"
```
+
There is a known bug in the boot-loader, that prevents you from + loading an alternate kernel, so testing your kernel is a bit risky. + When booting the loader from the OpenFirmware prompt, give it a + partition which is either non-existent, doesn't have a kernel to load, + or isn't a UFS partition: +
```
0 > boot hd:loader hd:0
```
+ At this point, you can set currdev and manually load a kernel: +
```
OK set currdev=hd:14
+OK load /boot/kernel/kernel.save
```
+
Some patches are needed to build your own world and kernel: +
- + RELENG_5 (GCC 3.4.2): + rs6000.c.diff + and + sysv4.h.diff +
- + HEAD (GCC 3.4.4): + rs6000.c.diff + and + sysv4.h.diff +
