Fw: Booting genode/nova

Hi Norman, -----UrsprÃ¼ngliche Nachricht----- From: Norman Feske Sent: Friday, May 2, 2014 11:33 AM To: genode-main(a)lists.sourceforge.net Subject: Re: Booting genode/nova >For testing, it is very helpful to have Genode's LOG output available, >which is directed to the comport. Unfortunately, modern PCs don't have a >comport anymore. However, on most Intel-based PCs, there exists a >feature called AMT that allows for sending comport output over the >network. If you are interested in exploring this, it is worthwhile to >search for 'amtterm'. Finally got the x201 you supposed and tried to configure amt. I tried the following: on the x201 enable AMT, setup a new user wolfgang with password and enable SOL. I set a IP4 adress of 10.1.1.2. With the username and password i can log into the AMT web site of the computer. On a hp i tried the commands from http://genode.org/documentation/release-notes/13.05 (On the client i installed amtterm 1.3 from repository.) export AMT_TEST_MACHINE_IP=10.1.1.2 export AMT_TEST_MACHINE_PWD=Test$$44$$ (yep i know, but the machine cannot connect to the outside world) and tried RUN_OPT="--target amt" make run/printf The x201 does not seem to get touched - even with disconnected network cable the test is succesful. I honestly does not understand amt. I tried to use amtterm instead to try out the connection. With amtterm i get a "amtterm: AUTH - ERROR (failure) amtterm: ERROR: session authentification failed". I know that amtterm has nothing to do with genode directly, but if you are using it could you give a hint for the right direction? Best regards, Wolfgang

On July 29th of this year the seL4 is going to become free software. Is Genode going to support or it's already supporting this uKernel ???

Genode demo-cd and virtualbox
by Jorge Ventura 20 Jun '14

20 Jun '14

Because I didn't see any reference to VirtualBox but just for qEmu I would like to report the great success running the demo-cd under VB version 4.3.12 r93733 without any special configuration. The network driver and sound system is working perfectly. It's interesting also to report that I configured the virtual machine as type=other and version=L4. The version=L4 is not a must but it's remarkable to see that they are aware that the future is not Windows and Linux.

Audio-out test implementation
by unknown＠example.com 18 Jun '14

18 Jun '14

Hello everyone, I try to get the Audio-out test implementation running. When I start the test implementation, I get the following output: ... [init -> test-audio_out] C++ runtime: Genode::Parent::Service_denied ... To me it looks as if the build/bin/config file was misconfigured. It looks like <config> <parent-provides> <service name="CAP"/> <service name="LOG"/> <service name="RM"/> <service name="SIGNAL"/> </parent-provides> <default-route> <any-service><parent/><any-child/></any-service> </default-route> <start name="audio_out_drv"> <resource name="RAM" quantum="8M"/> <provides><service name="Audio_out"/></provides> </start> <start name="test-audio_out"> <resource name="RAM" quantum="1M"/> <config> <filename>audio1.raw</filename> <filename>audio2.raw</filename> </config> </start> </config> Do you have any idea for what I need to correct ? Moreover, there is another issue. The audio files needed to run the audio-out test are missing and the README file provided simply states 'The raw data must comply the Audio_out standard format.' Has anyone got the audio files ? Where can I get information regarding the aforementioned Audio_out standard format and are there any tools for converting audio files such as WAVs into Genode?s raw format ? Best regards Markus

Hello everyone, we have fixed the date for this year's Genode Hack'n'Hike. This is a yearly event where the Genode community gathers to contemplate new ideas together, visit beautiful nature sites at day light, and work on pet projects in the evenings. Genode Labs sponsors the event. There is no attendance fee. It goes without saying that everyone interested in Genode is welcome to join! This year's Hack'n'Hike will take place somewhere in Saxony or in the south of Brandenburg during 18th to 21st of September 2014 For planning the event, we have created the following topic at our issue tracker: https://github.com/genodelabs/genode/issues/1158 If you are interested to participate, please leave a message there, post to the Genode mailing list, or drop a note to: hacknhike@...1...

Question about the flow control in genode
by li94575 16 Jun '14

16 Jun '14

Hello, Recently, I was learning genode about the RPC process, and found that genode provides flow control policy between partitions by routing communication mechanism. I was wondering if I can achieve such a flow control policy in a partition (or process), which uses threads as the subject? If this is possible, how should I do?

AW: Block Cache
by Wolfgang Schmidt 15 Jun '14

15 Jun '14

Hi Stefan, Can You give a gibt for compatible x86 hw? I tried The democd on an FSC Athlon64 which did mit start at all. Does for example a comp list for nova exist? What so You mean with: it serves only one client- one client application?

Yes, Genode is able to run on top of Linux, mostly for development purposes. But Genode runs also directly on x86 hardware using the NOVA kernel, or Fiasco.OC kernel, or the OKL4 kernel, or Pistachio kernel. > Therefore multiple caches will be used before something goes to genode > a) the cache on a hdd > b) cache on a drive controller > c) the linux block cache If running on Linux yes, but normally it wouldn't make much sense to use an additional block cache here. > d) qemu As already said: you don't need to use Qemu.

Are all embeded devices usable with the cache? The block cache uses the block session of Genode. It uses exactly one block device, and serves exectly one client. As all block device drivers of Genode are implementing the block session interface, the block cache can be used on top of all block drivers, whether its a x86 AHCI driver, or MMC card driver of an ARM SoC, or whatever. > > Is there a way to mount a partition in genode with qemu without using caches > from c) and d) ? > Or is there a x86 hardware where genode can directly operate on? Qemu allows to define the caching policy of a hard drive (cache=none). I don't know whether it's possible to circumvent Linux block cache. I assume that's hard. But as mentioned above, you can use conventional x86 PC hardware. Regards Stefan > > As far as I have seen so far the disc cache of Linux does not seem to be > disablable.

Hi everyone, in preparation for my master thesis, i need to deploy the vmm demo on the i.MX53 quick start board. I followed Stefans instructions in this thread: http://sourceforge.net/p/genode/mailman/genode-main/thread/9167aa55bacd5e3f… , so i did the following: I am using the master branch of this repo: git@...116...:skalk/genode.git tool/create_builddir hw_imx53 BUILD_DIR=hw_imx53 cd hw_imx53 echo "SPECS += trustzone" >> etc/specs.conf echo "RUN_OPT = --target uboot" >> etc/build.conf make run/tz_vmm It starts compiling, after some time i get the following output: Program core/imx53/trustzone/core ASSEMBLE boot_modules.o LINK core make[1]: Leaving directory '/tmp/genode/hw_imx53' Error: Can't execute automatically on target 'uboot' Makefile:237: recipe for target 'run/tz_vmm' failed make: *** [run/tz_vmm] Error 255 What am I missing? Any help appreciated! kind regards David
