Editing Building FreeBSD World

[[Category:OtherOS]]

=Introduction=

* You can either cross-compile the FreeBSD world on your PC FreeBSD or compile it natively on PS3.
* Unfortunately, you can not change monitor resolution on PS3 FreeBSD dynamically yet. That means, you have to patch the loader and kernel syscon driver for your monitor resolution.

=Fetching Source Code=

<pre>
svn co svn://svn.freebsd.org/base/releng/9.1 /usr/devel
</pre>

Or use the head branch (very unstable):
<pre>
svn co svn://svn.freebsd.org/base/head /usr/devel
</pre>

=Kernel Patches=

* http://gitorious.ps3dev.net/ps3freebsd/kernel-patches

=Building World=

<pre>
cd /usr/devel

# First apply patches if you want

# Update LV1 calls

cd /usr/devel/sys/powerpc/ps3
awk -f ps3-hv-asm.awk < ps3-hvcall.master > ps3-hvcall.S
awk -f ps3-hv-header.awk < ps3-hvcall.master > ps3-hvcall.h

cd /usr/devel/sys/powerpc/conf
mkdir /root/kernels
cp GENERIC64 /root/kernels/PS3
ln -s /root/kernels/PS3
cd ../../..

env MAKEOBJDIRPREFIX=/usr/obj/PS3 make buildworld buildkernel installkernel installworld distribution \
	TARGET=powerpc TARGET_ARCH=powerpc64 KERNCONF=PS3 DESTDIR=/root/PS3

cd /root/PS3
tar cvJf ../freebsd_world.tar.xz .
</pre>

=Rebuilding Loader=

* If you make changes to loader source then you don't have to rebuild the whole world again. You can recompile the loader only. 

<pre>
cd /usr/devel
env MAKEOBJDIRPREFIX=/usr/obj/PS3 make TARGET=powerpc TARGET_ARCH=powerpc64 buildenv
cd sys/boot
make all install DESTDIR=/root/PS3
</pre>

=Rebuilding Kernel=

* If you change your kernel configuration or make changes to kernel source then you don't have to rebuild the whole world again. You can recompile the kernel only.

<pre>
cd /usr/devel
env MAKEOBJDIRPREFIX=/usr/obj/PS3 make buildkernel installkernel \
	TARGET=powerpc TARGET_ARCH=powerpc64 KERNCONF=PS3 DESTDIR=/root/PS3
</pre>

=Installing World on PS3 HDD=

* Use a PS3 FreeBSD LiveCD

==Creating New Filesystem==

<pre>
newfs -U /dev/ps3disk3p3
</pre>

==Extracting World==

* Store your FreeBSD world on a USB drive.

<pre>
mkdir /tmp/usb
mkdir /tmp/ufs

mount -t msdosfs /dev/da0s1 /tmp/usb
mount -t ufs /dev/ps3disk3p3 /tmp/ufs

cd /tmp/ufs
tar xvJf /tmp/usb/freebsd_world.tar.xz
</pre>

==/etc/fstab==

<pre>
/dev/ps3disk3p3         /       ufs     rw      1 1
/dev/ps3disk3p1         none    swap    sw      0 0
proc                    /proc   procfs  rw      0 0
</pre>

==/etc/rc.conf==

<pre>
hostname="freebsd"

ifconfig_glc0="SYNCDHCP"

sshd_enable="YES"

keyrate="fast"
keymap="us.iso"
#keymap="fr.iso"
#keymap="german.iso"
scrnmap="NO"
font8x16="iso15-8x16"
font8x14="iso15-8x14"
font8x8="iso15-8x8"
</pre>

==/etc/kboot.conf==

* My latest petitboot supports mounting UFS2 filesystems.

<pre>
freebsd=/boot/loader.ps3
</pre>
