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[edit | edit source]

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

Building the Toolchain[edit | edit source]

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

cd /usr/src
mv sys/arch/powerpc ~
tar xvzf ps3-111111.tar.gz
patch -p0 < build.sh.patch
patch -p0 < elf_machdep.h.patch
mkdir /usr/obj
cd tools
sh ./mkheaderlist.sh
cd ..
./build.sh -m ps3 -a powerpc64 tools

Compiling Kernel[edit | edit source]

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.
