| # Running skiboot and Linux in Mambo |
| |
| The POWER8 Functional Simulator (aka Mambo) is free to use but not |
| open source and is only supported on limited platforms. This is a |
| guide to getting started guide with it with skiboot and linux. |
| |
| ## Getting Started |
| |
| From a bare x86_64 Ubuntu 16.04 install, to running skiboot and linux |
| in the simulator, you can do do the following: |
| |
| ### Steps to get Running on Ubuntu |
| xterm is needed by the simulator. |
| ``` |
| apt-get install xterm |
| ``` |
| |
| ### Download mambo from IBM |
| Download systemsim-p8..deb from: |
| http://www-304.ibm.com/support/customercare/sas/f/pwrfs/home.html |
| ``` |
| dpkg -i systemsim-p8*deb |
| ``` |
| |
| ### Grab your skiboot, linux and initramfs images |
| How to build a skiboot.lid is in the top level README file. |
| |
| Use a 64 bit powerpc kernel here. If compiling yourself, we suggest |
| using powernv_defconfig. |
| |
| If you use op-build to build a full set of OpenPower images, you’ll |
| likely be able to extract skiboot, zImage.epapr (or vmlinux and |
| rootfs.cpio.xz) from output/images. We suggest using the |
| openpower_mambo_defconfig. |
| |
| ### Setup environment variables |
| Setup environment variables to point to your images |
| ``` |
| export SKIBOOT_ZIMAGE=$HOME/src/op-build/output/images/zImage.epapr |
| export SKIBOOT=$HOME/src/op-build/output/images/skiboot.lid |
| export SKIBOOT_AUTORUN=1 |
| ``` |
| If you want a vmlinux and separate initramfs you can also do this: |
| ``` |
| export SKIBOOT_ZIMAGE=$HOME/src/op-build/output/images/vmlinux |
| export SKIBOOT_INITRD=$HOME/src/op-build/output/images/rootfs.cpio.xz |
| export SKIBOOT=$HOME/src/skiboot/skiboot.lid |
| export SKIBOOT_AUTORUN=1 |
| ``` |
| |
| ### Run the simulator |
| ``` |
| /opt/ibm/systemsim-p8/run/pegasus/power8 -f $HOME/src/skiboot/external/mambo/skiboot.tcl |
| ``` |
| |
| This should open an xterm and start booting. It should take around |
| 20sec to get to a petitboot console. |
