# Script:  disk_launch
# Purpose: Launch an installed Slackware ARM host via QEMU
# Author:  Stuart Winter <mozes@slackware.com>
# Date:    24-Apr-2009
# Version: 1.01

# Select your root filesystem's format.
# By default Slackware uses 'ext4', but if you chose another, you
# need to uncomment it and comment out the others.
#
ROOTFSTYPE=ext4
#ROOTFSTYPE=ext3
#ROOTFSTYPE=ext2
#ROOTFSTYPE=xfs
#ROOTFSTYPE=reiserfs
#ROOTFSTYPE=jfs  ## Don't choose this one! see installation notes
#
# Select your root filesystem device.
# The installation notes recommend /dev/sda2
ROOTFSDEV=/dev/sda2

# If you want a VNC server instead of displaying to your
# vconsole/X, uncomment this - but note that the setting below
# offers no security - not even a password!
VISUALOUTPUT="-vnc :1"   ## Uncomment this if you want a VNC Server
#
# If you'd like to output the boot process to your terminal window
# on the host machine, uncomment the two lines below:
#VISUALOUTPUT="-serial /dev/tty -nographic"
#KAPPEND="console=ttyAMA0"

# Select your keyboard - this gets overridden by the OS when you
# choose your keymap, so it's not prudent to change it unless you
# have a non-standard keyboard such as a Mac (according to qemu(1)).
# If there is a problem when booting the OS, and you are dropped to
# a rescue shell, this may also be another reason to have a correct
# key mapping. 
#
# The best advise is that if you find that your keyboard is going
# crazy in QEMU, please set it to one in the list below ;-)
#
# The available keyboard options are:
#
# ar  de-ch  es  fo     fr-ca  hu  ja  mk     no  pt-br  sv
# da  en-gb  et  fr     fr-ch  is  lt  nl     pl  ru     th
# de  en-us  fi  fr-be  hr     it  lv  nl-be  pt  sl     tr
#
KEYBOARD="en-gb"

# If you are using bridged mode and have more than 1 QEMU host
# on your network, you'll need to set the MAC address:
# QEMU begins at 52:54:00:12:34:56 - so I increment it for
# each new host.
# MACADDR=",macaddr=52:54:00:12:34:57"

# If you're using a bridge on your X86 host, so that the Slackware ARM
# host can become a real host on your network with its own IP,
# uncomment the next line.  This requires a bit more setup on your
# host.  To begin with you may prefer to use NAT, as the installer does:
# NETTYPE="-net nic${MACADDR} -net tap,ifname=tap0,script=qemu-network-tun.sh"

# Using NAT - this is the easiest way, but your Slackware ARM host
# does not appear as a real host on the network:
NETTYPE="-net nic,vlan=0${MACADDR} -net user,vlan=0"

# Load the 'tunnel' interface module:
modprobe tun

# To open a serial console, you can pass "console=ttyAMA0" to
# QEMU's -kernel parameter
# And add this to the OS' /etc/inittab:
# s1:12345:respawn:/sbin/agetty -L ttyAMA0 38400 vt100

qemu-system-arm $VISUALOUTPUT $NETTYPE \

# Flattened Device Tree:
# You need qemu to be built with --enable-fdt
# which also requires the 'device-tree-compiler' package
# to be installed.
