NetBSD on PS3

• Ok, here i will start porting NetBSD to PS3 OtherOS++.
• It would be cool to have another BSD on PS3.
• Special thanks to Makoto Fujiwara and Tsubai Masanari for porting NetBSD to PS3.
• Any help is welcome. Come on BSD fans, let us run NetBSD on PS3.
• It is still work in progress and i'm not able to run NetBSD on PS3 yet.

Obtaining Source Code

1. cd /usr
2. export CVS_RSH="ssh"
3. export CVSROOT="[email protected]:/cvsroot"
4. cvs checkout -A -P src
5. ftp ftp://nandra.segv.jp/pub/NetBSD/ps3/ps3-111111.tar.gz

Building the Toolchain

I must say the toolchain is really super done. Linux really sucks in comparison with NetBSD or FreeBSD regarding toolchain and cross-compiling.

1. cd /usr/src
2. mv sys/arch/powerpc ~
3. tar xvzf ps3-111111.tar.gz
4. patch -p0 < build.sh.patch
5. patch -p0 < elf_machdep.h.patch
6. mkdir /usr/obj
7. cd tools
8. sh ./mkheaderlist.sh
9. cd ..
10. ./build.sh -m ps3 -a powerpc64 tools

===> Tools built to /usr/src/obj/tooldir.NetBSD-5.1-amd64 ===> build.sh ended: Sat Jan 7 15:34:30 CET 2012 ===> Summary of results:

Compiling Kernel

Modify Tsubai Masanari's source code to use current powerpc infrastructure of NetBSD else no chance that NetBSD will accept our port. Tsubai Masanari's source code uses powerpc64 arch which is NOT present in NetBSD source. Everything is in powerpc arch. Currently, NetBSD supports 64bit PowerPC arch only in 64bit bridge mode, that means 32bit kernel and user-space. 64bit bridge mode won't work on CELL cpu. It is not supported.

Booting with Petitboot on OtherOS++

Bootloader doesn't work yet but it looks very promising. I can run code in loader already.

1. kexec -l boot.elf
2. reboot
