by Norman Feske 23 Mar '15

23 Mar '15

Hello everyone, the date for this year's Genode Hack'n Hike held during 11-16 of September is approaching. Genode's developers will spend those days in the beautiful scenery of the Bohemian Switzerland, relaxing, hiking, and hacking on fun side projects. The Hack'n Hike will be the perfect setting for getting involved with the community, catching up, or just hanging out with the Genode crowd. There is still room for more participants. Genode Labs sponsors the event. So your participation/accommodation is free. If you like to join in, please get in touch by writing to hacknhike@...1... or commenting on https://github.com/genodelabs/genode/issues/793.

Virtualization with trustzone into mx53
by panton 23 Jan '14

23 Jan '14

Hello, I want to create a virtualized system with Genode in my imx53 board. At the moment, I am able to run Genode on the board with base-foc and also directly on hardware (base-hw). Thus, my plan was to run a linux kernel as a child node and hopefully run it into trustzone NS. Looking into Genode code I found base-hw/include/vm_session that seems to deal with virtualization. Furthermore there is a trustzone.cc into base-hw/src/core.., but without real useful code. I was wondering if there are implemented virtualization capabilities using trustzone or even without trustzone? If so, it would be great to have an example of how to use it. Thanks in advance for answers! Best regards, Pablo Anton

Latest Attempt at GENODE on NOVA
by Lonnie Cumberland 29 Dec '13

29 Dec '13

Greetings All, I have recently tried to start again from scratch to build the GENODE + NOVA for x86_64 per Normans instructions: ---------------------------------------------------- alternatively, you can use Genode directly on NOVA without the need for NRE or NUL. It is also possible to run virtual machines on top of NOVA + Genode. All three variants (NUL, NRE, and Genode) use the same user-level virtual machine monitor (VMM) called Seoul (formerly called Vancouver). For Genode, you can find the Seoul VMM at 'ports/src/vancouver/'. The actual Seoul 3rd-party code can be downloaded by issuing the following command from within Genode's 'ports/' repository: make prepare PKG=seoul You will also need to download the C runtime as needed by Seoul and the x86emu needed by the VESA graphics driver. This can be done by changing to the 'libports/' repository and issuing the following command: make prepare PKG="x86emu libc" You can try out Linux running on NOVA + Genode using the ready-to-use run scripts at 'ports/run/seoul-*'. For example, to see a graphical Linux desktop on top of NOVA + Genode, execute the following command from within your build directory. Please make sure to have the 'libports' and 'ports' repositories enabled in the 'etc/build.conf' file of your build directory. make run/seoul-fancy By default, the build system will try to run the resulting boot image in Qemu, which is extremely slow (Qemu executes NOVA, which executes Genode, which executes Seoul, which executes Linux). But you can write the corresponding ISO image to a USB stick and boot it on a real machine. The machine must have VT enabled in the BIOS. dd if=var/run/seoul-fancy.iso of=/dev/your_usb_stick_device bs=1M The scenario will show Genode's launchpad, where you can start a virtual machine by clicking on the blue text labeled "init". A new window will appear with Tinycore Linux booting. Given that your machine is connected to the internet (and a DHCP server is running on your network), you can even browse the net using Firefox. You can start a second Linux instance by clicking on the "init" button again. In this scenario, each virtual machine is just a regular node of Genode's process tree, subjected to the same rigid security regime as in effect for all processes of the Genode system. I wish you a lot of fun with exploring the possibilities. All the best and happy New Year! ---------------------------------------------------- With that in mind, I started to write down each step that I have been taking in order to show the list how far I have gotten before something errors out. Here is what I have done so far: ----------------------------------------------------- Purpose to build Genode on top of NOVA hypervisor 1. Setup base plaform Debian 7.2 (64-bit) in Virtualbox (4.3.6 r91406) 2. Get the latest Genode git clone https://github.com/genodelabs/genode.git 3. Download toolchain: genode-toolchain-12.11-x86_64.tar.bz2 or genode-toolchain-12.11-x86_32.tar.bz2 http://sourceforge.net/projects/genode/files/genode-toolchain/ 64-bit in my case. 4. Install Toolchain: sudo tar xPfj genode-toolchain-12.11-x86_64.tar.bz2 5. Go into Genode directory: cd ~/genode/ 6. Go get the Seoul VMM into ports directory: cd ~/genode/ports/ make prepare PKG=seoul 7. Go into libports and get C runtime as needed by Seoul and the x86emu needed by the VESA graphics driver: cd ../libports make prepare PKG="x86emu libc" 8. Go into the desired base directory (NOVA in this case): cd ~/genode/base-nova/ Prepare the Nova base: make prepare 9. Go into the base Genode directoy and setup the build directory (ie.. gnova64) ./tool/create_builddir nova_x86_64 BUILD_DIR=gnova64 10. Go into the build directory and edit the etc/build.conf. Enable 'libports' and 'ports' repositories in the 'etc/build.conf' file of your build directory: cd ~/genode/gnova64/etc Use Nano or similar to edit etc/build.conf to remove "#" in front of needed REPOSITORIES. nano build.conf --------------------------------------------------------------------------- . . . # # Ports of popular open-source libraries and the C library. # # Make sure to execute 'make prepare' in 'libports' prior building. # REPOSITORIES += $(GENODE_DIR)/libports # # Qt4 tool kit # # The 'qt4' repository depends on 'libc' and 'libports' # Make sure to execute 'make prepare' in 'qt4' prior building. # REPOSITORIES += $(GENODE_DIR)/qt4 # # Ports of popular 3rd-party applications # # The 'ports' repository depends on 'libc', 'libports', and 'qt4'. # Make sure to execute 'make prepare' in 'ports' prior building. # REPOSITORIES += $(GENODE_DIR)/ports . . . ---------------------------------------------------------------------------- Then go to each directory and do "make prepare" just to be sure. cd ~/genode/ports; make prepare cd ~/genode/libports; make prepare ERROR HERE------------------------------- --2013-12-26 11:12:20-- https://www.openssl.org/source/openssl-1.0.1c.tar.gz Resolving www.openssl.org (www.openssl.org)... 185.9.166.106 Connecting to www.openssl.org (www.openssl.org)|185.9.166.106|:443... connected.

Genode Clarification Please
by Lonnie Cumberland 26 Dec '13

26 Dec '13

Greetings All, I am new to Genode and think that it is very nice solution for a microkernel OS for which I am trying to learn more about as it evolves into a fully fledged general operating system as I think that it has the potential to be much better than the majority that are currently available although it still seem to be a long ways from production quality at the moment. One thing that I am not clear about, and please forgive this question if it is a bit elementary as to something simple that I should have been able to ascertain, but I am confused on exactly where the Genode OS framework fall into place as an independent OS. The basis of my question is from the reading that I have been doing on the Genode website in which I can see that it can be compiled to run on baremetal as you would expect an OS to do, but why is it als able to be compiled to be used with other base platforms? I can understand why it might be used with NOVA, which is a microhypervisor and thus Genode could run as a user-land OS in a VM, but I do not see why Genode would need to be compiled against the other base-platforms like Linux, Fiasco, .... Can someone please clarify this for me?

Re: Porting on i.MX6
by Aditya Kousik 23 Dec '13

23 Dec '13

Hello Firstly, thank you for patiently replying to our queries and debugging issues so far. We're trying to port Genode onto an i.MX6, which we've realised is no easy task. Our initial approach to this was to tweak existing i.Mx53 files and make corresponding changes (arm cortex a9, created imx6 related folders in include). As pointed out to us by Stefan, this was completely off track as the memory layout may be mixed up (or many more issues). Here's a brief reboot of our attempt: 1. edit create_builddir to add a rule for imx6 board and added build.conf.hw_imx6 in builddir folder. 2. modify board_base.h in base/include/platform/imx6/drivers and fill with addresses by referring to the imx6 reference manual. (We also added CORTEX_A9_CLOCK and private memory base) 3. read through the Makefile and added spec-hw_imx6 and spec-platform_imx6 respectively. 4. created imx6 folder with files in os/include/platform/imx6 as well. (All with imx53 as reference) Make: Since the drivers for imx6 would take a long time to code, we are NOT running demo.run. We tried to build hello.run (without building drivers/timer) according the instructions given in your site. We're getting the following error: Program core/imx6/core COMPILE _main.o ASSEMBLE boot_modules.o COMPILE console.o COMPILE context_area.o COMPILE cpu_session_component.o COMPILE cpu_session_support.o ASSEMBLE crt0.o COMPILE dataspace_component.o COMPILE dump_alloc.o COMPILE io_mem_session_component.o COMPILE io_mem_session_support.o COMPILE irq_session_component.o COMPILE kernel.o COMPILE kernel_support.o COMPILE main.o make[3]: *** No rule to make target `mode_transition.o', needed by `core'.

A20-OLinuXino-MICRO-4GB
by buzz heavyyear 18 Dec '13

18 Dec '13

Hi I have just received a new board with a dual core cortex a7, the A20-OLinuXino, which I'd like to set up and add to the genode tree - currently more pressing than the RPi! I'm no Arm expert, but I'm assuming that I can take most of the existing arm_v7 and a9 code in base-hw and just use this for setting up an a20olinuxino environment and building an image? https://www.olimex.com/Products/OLinuXino/A20/A20-OLinuXino-MICRO-4GB/open-… CheersNick
