Genode on the Fiasco.OC microkernel
|
|
===================================

|
Fiasco.OC is a microkernel developed by the OS group of the TU-Dresden. It's
|
|
an object-oriented capability-based system for x86, ARM and PowerPC platforms.
|
|
|
|
This document provides brief instructions about downloading, building and
|
|
booting the Fiasco.OC version of Genode.
|
|
|
|
|
|
Prerequisites
|
|
#############
|
|
|
|
You need certain tools to use the Fiasco.OC build system. On Debian/Ubuntu
|
|
systems you have to install the following packages:
|
|
|
|
! apt-get install make gawk pkg-config subversion patch
|
|
|
|
Moreover, you need to download and install the tool-chain used by Genode. Have
|
|
a look at this page:
|
|
|
|
:[http://genode.org/download/tool-chain]:
|
|
Genode tool-chain
|
|
|
|
If you want to use the so called run-scripts in Genode, a mechanism that
|
|
automates building, integration and testing of components, you have to install
|
|
the following, additional package:
|
|
|
|
! apt-get install expect
|
|
|
|
|
|
Building the Fiasco.OC version of Genode
|
|
########################################
|
|
|
|
The current version of Genode is available at the public subversion repository:
|
|
|
|
:http://genode.org/download/subversion-repository:
|
|
Information about accessing the Genode public subversion repository
|
|
|
|
After you've fetched the Genode source tree from the subversion repository, or
|
|
downloaded the latest release tar archive, you need the Fiasco.OC source code,
|
|
its kernel-bindings, additional bootstrap tools etc. To simplify that step,
|
|
you can use a Makefile in the 'base-foc' directory of the Genode source tree,
|
|
just do:
|
|
|
|
! cd base-foc
|
|
! make prepare
|
|
|
|
This will install all necessary third-party source code in the 'contrib' folder.
|
|
|
|
For the vesa driver on x86 the x86emu library is required and can be downloaded
|
|
and prepared by invoking the following command from within the 'libports'
|
|
directory:
|
|
|
|
! make prepare PKG=x86emu
|
|
|
|
Now, go to a directory where you want the Genode/Fiasco.OC build directory to
|
|
remain. Use the helper script in the 'tool' directory of the Genode
|
|
source tree to create the initial build environment. You need to state the
|
|
build directory you want to create, and the hardware architecture to run
|
|
Fiasco.OC/Genode on. Choose 'foc_x86_32', 'foc_x86_64', or 'foc_pbxa9'
|
|
depending on whether you want to build for the 32-bit or 64-bit X86
|
|
architecture, or for ARMs Cortex-A9.
|
|
|
|
! <genode-dir>/tool/create_builddir foc_x86_32 \
|
|
! BUILD_DIR=<build-dir>
|
|
|
|
Now, go to the newly created build directory and type make:
|
|
|
|
! cd <build-dir>
|
|
! make
|
|
|
|
This will build the Fiasco.OC kernel, its bootstrap code, and every Genode component,
|
|
that runs on top of Fiasco.OC.
|
|
|
|
If you just want to give Genode/Fiasco.OC a try, you can call e.g.: the demo run-script
|
|
instead of building everything:
|
|
|
|
! cd <build-dir>
|
|
! make run/demo
|
|
|
|
|
|
Running L4Linux on top of Genode
|
|
################################
|
|
|
|
To get the L4Linux running on top of Genode, you have to change to the
|
|
'ports-foc' repository within your Genode source tree and do a 'make prepare':
|
|
|
|
! cd ports-foc
|
|
! make prepare
|
|
|
|
This will fetch the currently supported version from the L4Linux subversion
|
|
repository, and apply a patch to it, that is needed to execute it on top of
|
|
Genode.
|
|
|
|
Before compiling L4Linux for Genode/Fiasco.OC you have to integrate the 'ports-foc'
|
|
repository into your build environment. Therefore edit the 'etc/build.conf' file
|
|
in your build directory, and uncomment the following line:
|
|
|
|
! REPOSITORIES += $(GENODE_DIR)/repos/ports-foc
|
|
|
|
After that you can build and run L4Linux by issuing:
|
|
|
|
! make run/l4linux
|
|
|
|
in your build directory. This run-script boots a single L4Linux instance into
|
|
a minimal console environment. After booting completes, the run-scripts tries
|
|
to download the Genode project webpage via the 'wget' tool within the L4Linux
|
|
environment. If all wents fine the run-script completes successfully.
|
|
|
|
|
|
Integration of Fiasco.OC with Genode
|
|
####################################
|
|
|
|
If you don't want the Genode build system to build the Fiasco.OC kernel for
|
|
you, but you want to provide your own version, you have to state in the
|
|
'etc/foc.conf' file within your build directory, where to find it:
|
|
|
|
! L4_BUILD_DIR = <l4re-build-dir>
|
|
! KERNEL = <fiasco.oc-kernel-binary>
|
|
|
|
The first variable states where to find the kernel bindings (the L4RE build
|
|
directory), the second one states where your kernel binary can be found.
|
|
After adding these variable to the file, you have to do a full cleanup
|
|
in your build directory to ensure, that the right bindings are used:
|
|
|
|
! make cleanall
|
|
|
|
From now on, run-scripts will use your provided kernel.
|
|
