Genode and Android
by Steven Harp 28 Mar '17

28 Mar '17

If one wanted to run Android OS on ARM hardware with Genode underneath, what are the available options? On x86, Virtualbox ought to be up to the job, but without something like the (seemingly offline) L4Android port, the options for virtualizing Android on Genode appear limited. Has anyone tried this recently, and if nothing off the shelf will do it now, what path looks most promising? Steve Harp

GSOC 2017 - Project Enquiry
by Arun Kumar 27 Mar '17

27 Mar '17

Hi Mentors for GSOC, My name is Arunkumar Ravichandran. I have been admitted to masters program in communications engineering at Univ of California, San Diego. I currently live in Chennai, India. I would love to work on a Genode project under the FOSDEM organization in GSOC 2017. I would like to work on this project: integrating support for the SAFE network as a Genode component. Already in Genode, all the components are provided access using the capabilities. Similarly SAFENET tries to achieve the same using the access tokens. Could you please provide the scope/requirement for this implementation. Based on this, i can respond back with the design for implementing SAFEnet in Genode. Thanks, Arun

[Genode] Suggestion about mailing list subject
by Martin Iturbide 27 Mar '17

27 Mar '17

Hello to all. I was wondering if it can be useful to configure the mailing list to include on the subject (before the text) something like [Genode] or [Genode-Main] . I know that it is easy to set a rule and folder for the mailing list messages on the mail client, but in some other cases I like to identify visually and fast the messages that are from this mailing list in a group of mails. This is just a thought, I don't know how hard or easy will be to configure this on the sourceforge mailing lists. Regards -- Martín Itúrbide http://www.os2world.com martin@...476... martiniturbide@...9... Quito - Ecuador

Exceptions in with_libc not working
by Boris Mulder 22 Mar '17

22 Mar '17

Hi all, Whenever I throw an exception somewhere in code inside a with_libc lambda expression, and try to catch it outside of that block, it will not catch that exception. Example: |t||ry {| | Libc::with_libc([&] () { ... throw E||xception(); ... } );| |} catch (Exception &e) {|| Genode::log("caught");|||| } |The "caught" will never be printed in this case. What can I do to fix/work around this? -- Met vriendelijke groet / kind regards, Boris Mulder Cyber Security Labs B.V. | Gooimeer 6-31 | 1411 DD Naarden | The Netherlands +31 35 631 3253 (office)

AMT SOL on Lenovo X250
by Martijn Verschoor 16 Mar '17

16 Mar '17

Dear subscribers of the Genode mailinglist, After some help by Christian Prochaska I managed to setup AMT SOL on Lenovo X250. I thought I’d share my experience because there are some pitfalls of which I was unaware. On older systems like the Lenovo X201, you had to enable Legacy Redirection Mode for SOL to work. Unfortunately for the X250 this option is no longer available in the AMT <Ctrl-P> boot menu. Instead you can use wsman to set the ‘ListenerEnabled’ flag of the AMT_RedirectionService to true, and SOL will be available. Please note that you cannot run wsman on the machine that you're trying to configure. wsman connects to the amt interface of the target machine and the amt interface is not accessible from the machine itself. So, on another machine, make sure you have installed wsman: $ sudo apt-get install wsmancli Then inspect the ListenerEnabled flag with wsman: $ wsman get http://intel.com/wbem/wscim/1/amt-schema/1/AMT_RedirectionService -h <TARGET_MACHINE_IP_ADDR> -P 16992 -u admin -p ‘<YOUR_AMT_PASSWORD>' If set to false, set it to true using: $ wsman put http://intel.com/wbem/wscim/1/amt-schema/1/AMT_RedirectionService -h <TARGET_MACHINE_IP_ADDR> -P 16992 -u admin -p ‘<YOUR_AMT_PASSWORD>' -k ListenerEnabled=true For debugging you can increase the verbosity with the -d flag, e.g. -d 6. Also note that the uri is not a url for a file on the Intel site ;-) Thanks to Christian!

Moving from 16.11 to 17.02 with base-hw kernel
by Bob Stewart 14 Mar '17

14 Mar '17

Hi, I'm in the process of moving my TI AM437x (Cortex A9) Genode implementation to 17.02 and trying to get familiar with the lower level structural changes (of which there are many) in base-hw as I progress. After cleaning up some of my deprecated usages, correctly wrapping my components that used libc, and ignoring for now the new unified sd_card driver implementation, I got a successful build which unsurprisingly wanders off into oblivion after completing "kernel initialization". The first question I have is from the build output which includes the line "core link address is 0x91000000" Where is that address generated and what is its purpose? It looks like my load address plus half the available ram. The console log from the boot process (attached) shows some strange memory allocations for IO memory : :io_mem_alloc: Allocator 0x910d012c dump: Block: [0x0,0x80449000] size=0x80449000 avail=0x80449000 max_avail=0x80449000 Block: [0x81000000,0x8145d000] size=0x45d000 avail=0x45d000 max_avail=0x8044900 Block: [0xa0000000,0xffffffff] size=0x5fffffff avail=0x5fffffff max_avail=0x5ff => mem_size=3767164927 (3592 MB) / mem_avail=3767164927 (3592 MB) How are the above blocks being allocated as io memory? In prior releases (the "good-old-days"), a Native_region was declared to exactly define the regions of physical memory that were to be tagged as io memory. There appears to be no equivalent in 17.02. What am I missing? Bob

lxip echo not working
by Boris Mulder 13 Mar '17

13 Mar '17

Hi, I'm trying to play around with the new lxip vfs plugin. First, I tried running the echo_udp.run test (on linux), but when I run the echo component it exits with the following error message: "Error: no plugin found for socket()" However, since I did create a network interface I am able to ping the network stack. Other than the IP address I did not change anything in the config (or somewhere else). Can anyone help me out? -- Met vriendelijke groet / kind regards, Boris Mulder Cyber Security Labs B.V. | Gooimeer 6-31 | 1411 DD Naarden | The Netherlands +31 35 631 3253 (office)

Cannot get NOVA demo to run on qemu
by scott constable 08 Mar '17

08 Mar '17

Hi All, I originally posted this on github, then thought it might be better to post here.. I followed the directions in the Genode book, Section 2.4, to build and run the nova demo on x86_64. I'm using Genode 17.02, and qemu 2.7.1 on Ubuntu 16.04 LTS. When I run $ make run/demo everything seems to build just fine, and then qemu launches. The GUI for the demo is then displayed, but freezes immediately. The scout window is displayed with the green x-ray shading, but I cannot move or manipulate it at all. The entire GUI just remains frozen, and I am unable to do anything. Here's the output when I run make run/demo: including /home/scott/Documents/genode/tool/run/power_on/qemu including /home/scott/Documents/genode/tool/run/log/qemu including /home/scott/Documents/genode/tool/run/image/iso including /home/scott/Documents/genode/tool/run/boot_dir/nova including /home/scott/Documents/genode/repos/os/run/demo.run building targets: core init drivers/timer server/nitpicker app/pointer app/status_bar app/xray_trigger server/liquid_framebuffer app/launchpad app/scout test/nitpicker server/nitlog drivers/framebuffer drivers/input server/report_rom server/rom_filter drivers/platform drivers/acpi server/report_rom drivers/platform/spec/x86/device_pd spawn make core init drivers/timer server/nitpicker app/pointer app/status_bar app/xray_trigger server/liquid_framebuffer app/launchpad app/scout test/nitpicker server/nitlog drivers/framebuffer drivers/input server/report_rom server/rom_filter drivers/platform drivers/acpi server/report_rom drivers/platform/spec/x86/device_pd make[1]: Entering directory '/home/scott/Documents/genode/build/x86_64' Makefile:134: target 'server/report_rom' given more than once in the same rule checking library dependencies...
