TZ_VMM demo on i.mx53
by lzSun 11 Sep '18

11 Sep '18

Hello, I am new to Genode and the version I am using is 18.05. I am trying to boot genode on the secure world and linux on normal world on i.MX53-QSB board. I follow steps in this link: https://sourceforge.net/p/genode/mailman/message/33588666/. The system can boot successfully ,but after the linux started，it periodically print this message: mmc0: Timeout waiting for hardware interrupt. mxsdhci: ============== REGISTER DUMP ============== mxsdhci: Sys addr: 0x00000000 | Version: 0x00001201 mxsdhci: Blk size: 0x00000000 | Blk cnt: 0x00000001 mxsdhci: Argument: 0x00000c00 | Trn mode: 0x341a0000 mxsdhci: Present: 0xff880008 | Host ctl: 0x00000121 mxsdhci: Clock: 0x000010ff mxsdhci: Int stat: 0x00010001 mxsdhci: Int enab: 0x107f010b | Sig enab: 0x107f000b mxsdhci: Caps: 0x07f30000 mxsdhci: =========================================== I am not sure whether this is normal, or it's because something wrong.And I have a few question about the TZ_VMM demo on i.MX53 board hope to get help: 1. I looked up the code in repos/os/src/server/tz_vmm, in target.mk file, there's only empty.cc was declared to be compiled. So how can other files can be compiled and used? 2. I want to implement a secure app in Genode OS and provide service to normal world.But I have difficult to achieve this goal. To my understanding, I should implement the server module that can be used by VMM. Also, I should design help module in the linux kernel which uses SMC instruction to trap to VMM. Is it right? Actually, in tz_vmm dictionary, I can only see a block driver and serial driver which are used to handle block and serial driver smc respectively. So I don't know where can I add my code to serve normal world's smc request. Is there any suggestion or guidance that I can refer to? Best Regards,

Genode on AMD SB7x0/SB8x0/SB9x0
by Nobody III 11 Sep '18

11 Sep '18

I've had issues with interrupts on Genode on my desktop computer with an AMD chipset. In particular, the USB and AHCI drivers both get stuck waiting for interrupts. However, the VESA framebuffer driver works fine. I have tried using ACPICA to solve my issues, but with no success. I recently bought a PS/2 mouse, and it works just fine. Also, I recently installed an Intel wireless card, which Sculpt was able to detect. When I selected WiFi, the driver was able to detect nearby wireless networks. I have not been able to test whether I can connect yet, because I don't have a PS/2 keyboard. I'll try inserting my own wifi_config XML file with an SSID and password into my Sculpt image tomorrow, and then I can report on whether that works. What does this new information indicate?

openssl port
by Steven Harp 10 Sep '18

10 Sep '18

Is there some chance that the OpenSSL port will be upgraded in the near future? This port currently references * 1.0.1i *, which is no longer supported. (Versions 1.0.2p or 1.1.0i are still supported.) Given OpenSSL's relevance to features like native stub resolver, this might be a good opportunity to upgrade? // Steve Harp

Sculpt/wifi_drv regression: no IP address
by Nobody III 10 Sep '18

10 Sep '18

I updated to the 18.08 Genode release, built a Sculpt image, then booted it on my Dell Latitude 6430u laptop. I discovered that the WiFi driver, which worked in 18.05 (Sculpt TC) no longer works properly. In particular, the WiFi driver detects the access points and can connect to them, but doesn't get an IP address. I tried multiple access points, both my wireless router and my phone. With my phone, I used a clean lowercase alphabetic SSID ("bensphone"), to avoid any issues with problematic characters. I am using an Intel Ultimate-N 6300 wireless card.. Wired networking still works.

missing symbols for qt5_widgets
by Nobody III 07 Sep '18

07 Sep '18

When linking object code that includes a custom subclass of QPlainTextEdit, I get the following error: undefined reference to `typeinfo for QPlainTextEdit' I have been able to solve this problem by keeping more of the qt5_widgets symbols than those available in the depot API package, which are obtained from https://github.com/cproc/genode-symbols. When looking at the symbols file, I see that the typeinfo and vtable symbols were manually added for some Qt5 widget classes. Given the commonly-used ability to inherit Qt5 classes, wouldn't it be best to keep these symbols for all classes? The classes with names that end in Private could be split into a separate API package for compatibility and/or to reduce the size of the symbols lists and the resulting .lib.so files.

some recipe hashes need to be updated
by Nobody III 06 Sep '18

06 Sep '18

I noticed while building Qt5 packages for Genode 18.08 that mesa and qt5_dejavusans needed their hashes updated before I could build them. Also, I couldn't prepare the fatfs port without updating the hash for ff13b.zip and then for fatfs.port.

Possible Sculpt VC Problem On VirtualBox
by John J. Karcher 04 Sep '18

04 Sep '18

Hello, Note: Please disregard this if you can't reproduce it - I can wait for the official images. I built Sculpt VC from GitHub (both "disk" and ISO images), but there seems to be a problem with the USB pointing device in VirtualBox. (I tested using the VM from the Sculpt TC appliance, so there shouldn't be a VM configuration problem.) Leitzentrale displays fine, with the Manager window, Log window, and the new VC Diagram. The F12 key works to show/hide Leitzentrale, so I know the system is alive, but the mouse doesn't work. In the Log window, the following is the only relevant message that stays long enough to read: [leitzentrale -> wm] Warning: no focus model available There are other USB-related messages, but without the mouse, I don't know how to examine the log. Thanks! -- John J. Karcher devuser(a)alternateapproach.com

Caution: potential loss of local changes when preparing dde_linux
by Norman Feske 03 Sep '18

03 Sep '18

Hello, I want to bring the following issue to your attention: https://github.com/genodelabs/genode/issues/2959#issuecomment-418133022 Please be extra careful when issuing a 'prepare_port dde_linux' command! It works well when issued for the first time. But should you issue it twice, you are at risk of losing local changes within your genode git tree. See the description given in the linked issue for the details. To be safe, I recommend removing any existing 'contrib/dde_linux-*' directories manually before issuing the 'prepare_port dde_linux' command. The following commit contains an interim fix that I merged to the master branch just now: https://github.com/genodelabs/genode/commit/bbff6ae52998c3faeb41fd508e99878… However, note that the commit is not able to fix the issue for an already prepared 'contrib/dde_linux-' directory. So better remove such directories after updating to the current master branch. Regards Norman -- Dr.-Ing.

WARNING: do not (re-) prepare dde_linux port!
by Stefan Kalkowski 03 Sep '18

03 Sep '18

Dear genodians, a recent regression within the dde_linux port description may lead to data-loss! When preparing the dde_linux port although it is already available, e.g., to overwrite local changes in the contrib sources, non-commited changes of any git repository above your contrib directory (normally this will be your genode repository) will get reset hard. This regression went into the codebase with the update of 'wpa_supplicant' within the last release. Have a look at: https://github.com/genodelabs/genode/issues/2959 for further details. We will provide a fix for this issue soon. In the meantime it is safe to do a prepare_port for dde_linux when it is not prepared yet. Sorry for the inconvenience & regards Stefan -- Stefan Kalkowski Genode labs https://github.com.skalk | https://genode.org
