Compiling kexec for PS3 Linux

• To compile the latest kexec-tools on Debian Squeeze, you have to install autoconf and libc6-dev-ppc64 packages

$ git clone git://git.kernel.org/pub/scm/utils/kernel/kexec/kexec-tools.git
$ cd kexec-tools
$ ./bootstrap
$ ./configure
$ make

Booting Linux 2.6 kernel with kexec on running PS3 Linux

• kexec-tools is very useful if you want to test a new Linux 2.6 kernel on PS3 without a long boot procedure with petitboot

# ./build/sbin/kexec -l /boot/vmlinux-2.6.38-rc4-00155-gb0fd285 --append="root=/dev/ps3dd1 video=720p"
# swapoff -a
# sync
# ./build/sbin/kexec -e
