Re: Reagaring Genode and USB Armory
by Agrawal, Utkarsh 03 May '16

Hello, The initial steps of compilation and building the SD card were not clear. It took me few days to understand whats going on with the building procedure. I will share the script file soon. There are some changes I am making to it. Then maybe you can incorporate it into the repository. I see that the wiki got updated. Thanks for that.

<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.

Is libc support sched_yield() on Fiasco+Genode?

Problem with the AHCI driver
by Charles HH 18 Apr '16

18 Apr '16

Hello, I'm trying to create a custom Turmvilla-like scenario on my computer, but I'm running into a problem similar to the one Nobody III experienced ( https://sourceforge.net/p/genode/mailman/genode-main/thread/20150601102048.…) : when trying to access a physical hard disk with ahci_drv and part_blk, both components are launched, and ahci_drv reports the ATA device correctly, but the session is never built (part_blk hangs somewhere in the Driver constructor and ahci_drv never executes the _create_session function of Root_multiple_clients). The test run script works perfectly on Qemu however, and the content of the drive is read correctly. I experienced the same issue on my laptop, but I couldn't get any debug information because it doesn't have a serial port. Enabling or disabling IOMMU didn't affect the outcome. Did I miss something or is the hardware I'm using simply unsupported (the computer from which the linked logs where obtained is a Dell Optiplex 7010 with a c216 chipset) ? Should I open a new issue on the GitHub ? Regards, Charles

Some inter thread/component communication questions
by Menno Valkema 14 Apr '16

14 Apr '16

Hi Everyone, I've some questions with regards to Genode synchronization features between threads and components. First a question about packet streams: 1) Can we expect the packet streams to deliver packets in order to the other component as a FIFO? Thus: can we expect the packet submitted first, to be delivered first at the other component? Also when bursts of packets are send through the packet stream? Other questions are with regards to synchronization between multiple threads within the same component: 2) Say we have 2 threads in the same component, where Thread A needs to sleep until an event occurs in Thread B. How to address this? If A and B were components, signals would be the answer. Would signals also work between threads within the same component or is there some other approach? 3) What if those same 2 threads need to exchange data? When data is shared between components, shared memory would be the answer. How to approach this with 2 threads within the same component. Setup a shared data space? Do those 2 threads share the same heap which we can use for this exchange? Thanks for thinking along. Kind regards, Menno PS. The first question is a repost, I noticed in my previous email the subject was partially discarded. Sorry about that. -- Cyber Security Labs B.V. | Gooimeer 6-31 | 1411 DD Naarden | The Netherlands | https://nlcsl.com

Shared Memory in tz_vmm demo
by Joseph Lee 14 Apr '16

14 Apr '16

Hi, I used "*dma_alloc_coherent( )"* as described in this thread ( https://sourceforge.net/p/genode/mailman/message/34685275/) to allocate shared memory between the trustzone worlds in the tz_vmm example on i.mx53 qsb. It works well. But my questions is how do we prevent the normal world from modifying this shared buffer while it is being used by the secure world. Thanks in advance for answers. Kind regards, Joseph
