Genode freezes on USB Armory
by Yevgeny Lavrov 17 May '16

17 May '16

Hi, after going through tz_vmm tutorial I was able to create uImage and put it on MicroSD card. However, when I try to boot it on Armory, Genode freezes all the way at the end. Below is what appears on the console after executing => ext2load mmc 0:1 0x74000000 /uImage => bootm 0x74000000 it freezes after "Debian GNU/Linux 7 usbarmory console" Am I missing something?

FYI: microkernel.info community site
by Jakub Jermář 17 May '16

17 May '16

Hello, just FYI, I have set up a simple web page[1] to promote the wider microkernel community and its goals. So far, the page comes with a brief description of the microkernel concept and an incomplete list of microkernel projects with links to each project's web. The description is made out of the first two sentences I found in the "What is XYZ" section or elsewhere on the web of the respective project. I also took the freedom to use the respective project's logo (or what I believed was the project's logo) for promoting it. I hope you will find this small web a good idea. It was inspired by a similar (though a little bit more informative) site set up by the unikernel community [2]. The sources of the [1] web are hosted on Github [3], so feel free to submit issues or PR to make the site better. Please send me a PM if there are any issues pertaining your project's cartouche that cannot be dealt with using Github. Thanks, Jakub [1] http://microkernel.info [2] http://unikernel.org/projects/ [3] https://github.com/jermar/microkernel.info

handling misbehaving filesystem drivers
by Nobody III 14 May '16

14 May '16

I'm planning on writing an fs_filter server for the desktop environment I'm developing. The server will combine access to multiple filesystems, much like the vfs server. I want to implement this feature in such a way that a misbehaving filesystem driver can't make the server hang. How should I do this?

Android no NW - i.MX53 QSB
by Tiago Brito 09 May '16

09 May '16

Hi, I'm trying to boot Android in the Normal World of an i.MX53 QSB using U-boot in the Secure World as the bootloader. I've adapted U-boot in order to switch to Normal World upon a SMC call. The Android version I'm using is Adeneo BSP for Android Gingerbread v4.3. Android boots fine when I disable the world switch in U-boot, but when I try to boot it in the Normal World it freezes in a Kernel Panic before running the Init. I followed the patch made by Stefan Kalkowski (as suggested in https://community.freescale.com/thread/308152 ) because I was experiencing a similar problem (FAILED TO RELEASE IRAM PARTITION). Unlike Miao Yu in that post my execution didn't stop there. I thought this would be enough to run Android in the Secure World (because this is what Stefan did) but apparently it didn't work. The problem remains the same. What happens is the kernel boots successfully and then the following flow occurs: (1) init_post() at kernel/init/main.c:826 (2) run_init_process() at kernel/init/main.c:817 (3) kernel_execve() at kernel/arch/arm/kernel/sys_arm.c:81 Inside kernel_execve() when we return to user space by manipulating the kernel stack (asm code below) it lauches a Kernel Panic and init is never executed. ASM CODE: asm( ... "b ret_to_user" : : "r" (current_thread_info()), "Ir" (THREAD_START_SP - sizeof(regs)), "r" (&regs), "Ir" (sizeof(regs)) : "r0", "r1", "r2", "r3", "ip", "lr", "memory"); In addition we noticed that the execution jumps to do_undefinstr at kernel/arch/arm/kernel/entry-armv.S:689 b do_undefinstr Besides this we confirmed that init is never executed by adding a print to init's main function (src/system/core/init/init.c:713). Thanks, Tiago Brito

new genode-desktop-environment repository
by Nobody III 05 May '16

05 May '16

I've created a new genode-desktop-environment repo. It currently contains my file manager, as well as a readme with my vision for a (somewhat) integrated desktop environment. Given that the components will be integrated to work together, I believe it makes sense to keep my repo separate from the genode-world repo.

Implementing additional SPECS in genode-world
by Johannes Schlatow 03 May '16

03 May '16

This is a follow-up of my previous approach [1] on separating the support of additional platforms from the official repository: In addition to the zynq_qemu SPEC variable that is already existent in the official repository, I'd like to add SPEC variables like `zynq_parallella` and `zynq_zedboard` to genode-world. However, I just ran into a conceptual problem that I'd like to discuss here. First, I can place a core.mk in genode-world/lib/mk/specs/zynq_parallella, which is then used as soon as I change the SPECS from zynq_qemu to zynq_parallella. I am also able to set the include directories properly. The point where I got stuck, however, is that I need to include the less-specific configuration files within base-hw, which I achieve by the following line: include $(call select_from_repositories,lib/mk/spec/zynq/core.inc) Now, the issue is that including makefiles from other repositories won't work properly. This is due to the fact that $REP_DIR (used e.g. in core.inc) will evaluate to `[...]/repos/world` and not `[...]/repos/base-hw`. Do you have any idea on how to work around this or even on how to improve the build system in order to support this use case? Cheers Johannes [1] https://github.com/genodelabs/genode/pull/1926

Re: Reagaring Genode and USB Armory

<Discussion moved from my private mail to the Genode mailing list> Hi Utkarsh, Regarding your installation script: I think, it is a good idea to share your experience with the community. However, I don't see which steps of this process are not covered yet by [1] and [2]. If there are such pitfalls, please let me know. If you agree, I would directly add them to [1] resp. [2]. Regarding the Wiki [3]: It was updated and, as I think, now gives a clearer view of the way towards a Genode hypervisor on the USB Armory. Regarding your USB-connection issue: IMO, the USB events that your dmesg shows are not from the integrated USB of the USB Armory but the UART-to-USB converter you've attached to the device. So, apparently you're missing feedback from the host controller at all. Could you please send the UART output of your USB Armory for further analysis?

Re: [tz_vmm] Build error (#2)

Hey Yevgeny, Am 17.04.2016 um 09:09 schrieb Yevgeny: > Yes, I've already tried: make run/tz_vmm, however, it doesn't create the > *uImage* in the *var/run/tz_vmm/* directory. A run script merely contains the common set-up of a Genode scenario. Thus, it doesn't create bootloader-specific output like a uImage. For such customization there is the file <builddir>/etc/build.conf. In your case you would need to add a line: RUN_OPT += --include image/uboot This is also documented in [1]. I think it would be the best if follow the tutorial in there. It describes the complete process how to create a bootable SD card with the tz_vmm script. > I started off with this tutorial: > https://github.com/inversepath/usbarmory/wiki/Genode-OS and everything > went fine untill this point: cp var/run/tz_vmm/uImage to SD_CARD.

If you try using the wrong tool chain, the build system should tell you and stop.

Is Foasco+Genode support sched_yield()?
by unknown＠example.com 20 Apr '16

20 Apr '16

Hi, all I use genode-16.02.tar.bz2 and prepare as follow. make -C repos/base-foc/ prepare ./tool/ports/prepare_port libc Then compile run/thread, it works well. ./tool/create_builddir foc_x86_64 BUILD make -C build_foc_x86_64/ run/thread I need call sched_yield() in this demo, but it dose not work. Is libc support sched_yield() on Fiasco+Genode? How can I use sched_yield()? int main(): transferred 111 MB to init int main(): --- init created, waiting for exit condition --- [init -> test-pthread] int sched_yield(): sched_yield not implemented -------------------------------------------------------- ZTE Information Security Notice: The information contained in this mail (and any attachment transmitted herewith) is privileged and confidential and is intended for the exclusive use of the addressee(s).
