Issues to build Sculpt with Sel4 kernel
by Nanfang Hu 29 Jul '19

29 Jul '19

I am trying to build Sculpt with Sel4 kernel. sudo make -C build/x86_64 run/sculpt KERNEL=sel4 BOARD=pc I run into error, "Could not allocate block in ext2 filesystem" It seems that I have increased file system size. Where is the place to make that change? Thanks Nanfang

Can QT-based "textedit" run successfully on Rpi 3 B+ ?
by kimberly nNA 22 Jul '19

22 Jul '19

Dear Genode team, I am Kimberly. I modified and added "textedit" on demo.run The link below is about the complete content of demo.run, textedit.config, runtime log, and also a result graph. https://docs.google.com/document/d/1gtQJOXG3IK2_h5xV5CLI1zy54Vil_Xu6HSJ3My6… The genode version is https://github.com/tomga/genode/tree/rpi3bplus_19.02 I tried this commands : $ ./tool/create_builddir *rpi3bplus* $ make run/demo KERNEL=hw This case successfully run on Rpi3 B+ But it had some errors when running textedit. I used USB to TTL Serial Cable to see the runtime log : =========================================== ... [init -> launchpad] starting textedit with quota 177873K [init -> launchpad] using unique child name "textedit" [init -> launchpad] Warning: textedit: service File_system not available [init -> launchpad -> textedit] Error: File_system-session creation failed (ram_quota=163840, cap_quota=12, tx_buf_size=131072, label="rw", root="", writeable=1) [init -> launchpad -> textedit] Error: failed to create <fs> VFS node [init -> launchpad -> textedit] Error: label="rw" ... ============================================ because of the errors, I couldn't "save" a new file. I wrote the config of "ram_fs" in demo.run : <start name="ram_fs"> <resource name="RAM" quantum="10M"/> <provides><service name="File_system"/></provides> <config>  <policy label="textedit -> root" root="/" /> </config> </start> something wrong with the node ? I am not familiar with writing the 'policy'. Thanks a lot ! 😊

How to see runtime log on Rpi3 B+
by kimberly nNA 20 Jul '19

20 Jul '19

Dear Genode team, I am Kimberly. I modified and added some apps on *demo.run* The genode version is https://github.com/tomga/genode/tree/rpi3bplus_19.02 I tried this commands : $ ./tool/create_builddir *rpi3bplus* $ make run/demo KERNEL=hw This case successfully run on Rpi3 B+ But I couldn't see the runtime log like as on x86_64 : ---------------------------------------------------------------------------------- ... [init -> drivers] Error: Could not open ROM session for "config" [init -> drivers] Error: Uncaught exception of type 'Genode::Rom_connection::Rom_connection_failed' [init -> drivers] Warning: abort called - thread: ep [init] child "drivers" exited with exit value 1 [init -> acpi_drv] Found MADT ... ----------------------------------------------------------------------------------- Like the above example, sometimes I want to debug errors on Rpi. Can I see the runtime log on Rpi3 B+ ? If it can, how to set on putty ? (p.s. I used *USB to TTL Serial Cable*) In putty configuration : serial line : /dev/ttyUSB0 speed : 115200 I also tried speed : 9600 But I still couldn't see runtime log. Maybe I have to refer to *gpio_signal.run* and then modify *demo.run* ? p.s. If I used *raspbian-stretch-lite.img* (*raspberrypi.com <http://raspberrypi.com> *provide it), I can see runtime log. Thanks a lot ! 😊

can't run noux_bash on Genode/seL4
by Alexander Tormasov 12 Jul '19

12 Jul '19

This is my first attempt to run Genode over seL4 inside VM. I take latest 19.05 version of Genode as recommended. I followed the instruction and now compile (in vmware vm with ubuntu, 64 bit) and able to run demo both inside vmware and qemu in my MacOS notebook. While I can say that work of demo is pretty unstable, it hangs under any attempt to run from launchpad nitpicker (just freeze mouse, no messages in the stdout log on host). It does not show any other windows except launcher, the only log message are: ... [init -> scout -> launchpad] starting testnit with quota 5896K [init -> scout -> launchpad] using unique child name "testnit" [init -> nitpicker] resource_request: ram_quota=0, cap_quota=4 [init] child "nitpicker" requests resources: ram_quota=0, cap_quota=4 I make run/noux_bash and run/noux_vim iso. both of them started successfully, but show me only black screen (both in vmware and qemu 3.1_01). Logs seems to be without errors… see below How I can see terminal prompt inside vm window ? Sincerely, Alexander Tormasov・ Bender: Hello World.

VirualBox + Genode on Muen SK Demo (iso)?
by Lonnie Cumberland 11 Jul '19

11 Jul '19

Hello All, Can some one please tell me if there is a demo available to show Virtualbox + Genode on Muen SK as I would really like to see it in action? Also, I heard there might be a NOVA + Virtualbox version somewhere as well.] Would like to download these to see them before I dig into things more, if possible. Thanks, Lonnie

Muen SK with VirtualBox VMM
by Lonnie Cumberland 11 Jul '19

11 Jul '19

Greetings All, I have been keeping an eye on Genode and in particular the NOVA Microvisor project for a long time now as I had always thought that it was a very good direction. As Genode has grown, it seems that more advancements are made all of the time which is awesome. Lately, I have turn my attention to Type-1 hypervisors like XCP-ng (Xen) and SmartOS while also digging into Separation Kernels a bit to see what they can offer. On that note, I have briefly started reviewing Muen SK and am trying to see what it can do, but came across the Genode project that is supposed to have Muen SK as the Host with a VirtualBox VMM for the Guest OS's. Can someone please tell me if there is any active work going on in this area as I am very interested in being able to run X86_64 Guests like Windows 7 Pro, Windows 10, and Linux all 64-bit? Thanks a lot in advance. Lonnie

Announcement: Sculpt OS version 19.07 released
by Norman Feske 09 Jul '19

09 Jul '19

Dear Sculpt OS users, I am happy to announce the release of Sculpt version 19.07, which incorporates the infrastructural improvements that came with Genode 19.05 [1]. The new tool chain, updated C runtime, and VFS infrastructure contribute visibly to a smoother user experience. Feature-wise, the addition of a clipboard mechanism paves the ground for new use cases and work flows between native components and virtual machines, allowing us to continue our transition from the work within virtual machines towards working in the native Genode environment. Our unique take on copy and paste is described in a dedicated article [2]. It goes without saying that the version comes with updated documentation [3].

vfs and file_system sessions: label too long
by Stefan Thöni 08 Jul '19

08 Jul '19

Hello Genodians We observed that when using a file system session for the vfs of a component with serveral parent init components with long names, the session connection failed. We believe this is caused by a label that got too long, because after we shortened the names of some components the session connection started working. The problem seemd to arise when the composite label exceedeed about 110 characters. Is there a specific limit on the length of labels? Is there a recommended workaround for that problem in a dynamic deploy environment? Kind regards Stefan -- Freundliche Grüsse Stefan Thöni Chairman of the Board Senior Security Architect +41 79 610 64 95 gapfruit AG Baarerstrasse 135 6300 Zug https://gapfruit.com
