# 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
|
|||
|
|
opal_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 Mambo to autmatically run *AND* exit when the system is
|
|||
|
|
shutdown (or has a HW crash) use this:
|
|||
|
|
```
|
|||
|
|
export SKIBOOT_AUTORUN=2
|
|||
|
|
```
|
|||
|
|
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.
