Genode over RPI
by Moh 30 Oct '18

30 Oct '18

Hi Genode, it has been long time since i played with Genode. In the past, I was able to run Genode over a RPI Model B+ V1.2. nowadays, I am trying to run the same code, so i got another RPI with the same version (i.e. Model B+ V1.2 ) but Genode was not able to boot. ACT light keeps lighting on. The PI which is working has a SOC SAMSUNG 431 K4P4G324EG- RGC2 while the other RPI has ELPIDA b4432bbPA-10-F. What i should change to get it work in the second RPI. best,

use hard float in Genode
by lzSun 30 Oct '18

30 Oct '18

Hello, I wonder whether I can use hard float in Genode. I am now using Genode 18.05 and was working on tz_vmm demo. I add "-CC_OPT += -mfloat-abi=hard -mfpu=vfp" in "/repos/base/mk/global.mk" file. It seems Genode tool chain can recognize this arguments,but print error message like this: "/usr/local/genode-gcc/bin/genode-arm-ld: error: supc++.o.tmp uses VFP register arguments, /usr/local/genode-gcc/bin/../lib/gcc/arm-none-eabi/6.3.0/../../../../arm-none-eabi/lib/libsupc++.a(class_type_info.o) does not" Form the error message, I guess it can't use hard float in genode because some static library in genode tool chain are build by soft float.Am I right? Any help will be OK, thanks. ------------------ Best wishes

HPET description not found when using UEFI boot with Nova
by Parfait Tokponnon 28 Oct '18

28 Oct '18

Hello all, We would like to test the UEFI framebuffer driver on Nova but the booting hangs just after this log on serial output : NOVA Microhypervisor v8-b156131 (x86_64): Oct 24 2018 16:04:18 [gcc 6.3.0] [MBI2] Command: $make run/demo KERNEL=nova with QEMU_RUN_OPT := --include power_on/qemu --include log/qemu --include image/uefi. QEMU emulator version 2.12.92 (v3.0.0-rc2-1-ga0c7f2c-dirty) This is a fresh Genode directory, just cloned from github. Actually, the booting hangs in function acpi::setup() because the HPET signature is not found when parsing the RSDT acpi table. Here is the list of signatures found in the acpi table : {FACP, APIC, SSDT, BGRT}. It is worth precising that it works fine when using the default (non-uefi) configuration. In this case, the acpi signatures list is {FACP, APIC, HPET, MCFG}. How can I fix this?

multiple devices, single driver
by Joel Nider 26 Oct '18

26 Oct '18

Hi, I have been looking at several drivers in Genode, and they all seem to have static data - specifically a Heap object and Root object. I am wondering with this kind of setup, is it possible to manage more than one device with a single driver? Thanks, Joel

Problem building src archive for component using Qt
by Duss Pirmin 23 Oct '18

23 Oct '18

Hello Genodeans I have a component that uses QToolButton. When I build it in my run script, the build works well. When I want to build my src package I get the following error message: button.o:(.data.rel.ro._ZTIN14Launcher_slice6ButtonE[_ZTIN14Launcher_slice6ButtonE]+0x10): undefined reference to `typeinfo for QToolButton' I have an other component that uses QPushButton where I can build the src archive. If I replace QPusButton with QToolButton in this component, I get the same error. I have tried to find out what might be the cause of it, but was not successful so far. Both of this buttons are in the library qt5_widgets (listed in the file repos/libports/lib/mk/qt5_widgets_generated.inc) Best regards, Pirmin

First steps with Sculpt on Dell XPS 13
by Roman Iten 17 Oct '18

17 Oct '18

Hi, for some time now I've been thinking about upgrading:) my day-to-day operating system from bare metal Linux to Sculpt. My Dell XPS 13 (9350) doesn't boot out of the box and I didn't had the time to investigate. Now the cool new report_dump gives me a chance to easily spot problems when using Sculpt on my laptop. So I prepared "Sculpt as a hardware-probing instrument" as described in the release notes [1]. But it seems like the XPS doesn't boot far enough as no reports are dumped... I suspected there's probably an issue related to the XPS' display resolution of 3200 x 1800. After all it's clearly been declared in Sculpts hardware requirements [2], that displays with a higher resolution than 2560 x 1440 "are not expected to work". I tried to artificially restrict the resolution to FHD [3]. The internal display still doesn't work, but when an external monitor is connected via an USB-C dock or adapter (!), the Leitzentrale is displayed and the report_dump subsystem dumps reports to the flash memory. Using Leitzentrale, I then updated config/fb_drv to enable the internal display with it's native resolution. All screens go blank, but now I have a log to share [4] (the reconfiguration of the fb_drv happens after line 500) So far my very first experiences with Sculpt on the Dell XPS 13. And here some related questions: 1. What do you think about the idea to generally restrict the resolution of the initial fb_drv configuration to the maximum resolution supported by Sculpt (instead of that of the connected display(s), which may break Sculpt), similar to [3]? This would also help if, for example, an external 4K TV is connected during boot. 2. On Sculpt, most/all? internal displays report only their native resolution. On the XPS this is 3200 x 1800 and I can't force a lower resolution. Although under Linux, xrandr reports a bunch of supported resolutions from 3200 x 1800 down to 640 x 360. Does the intel_fb_drv under Genode intentionally reports and supports only the native resolution? 3. Should I create an issue regarding [4] on GitHub? 4. Instead of installing Sculpt directly on my current laptop I consider to buy a new XPS 13 (9370). It has a Killer 1435 wireless module featuring a Qualcomm Atheros QCA6174A chip which seems to be supported on Linux by the ath10k module... Has someone any experience (or assumptions) whether there's a chance that it will work on Sculpt (right now or in the near future)? Cheers, Roman [1] https://genode.org/documentation/release-notes/18.08 [2] https://genode.org/documentation/articles/sculpt-tc [3] https://github.com/rite/genode/commit/ba65d4307e892320b791b52cdccca1d421694… [4] https://gist.github.com/rite/1e5602c9ed55a810fe9306475e3962c0#file-log-L501

measure execution time
by lzSun 16 Oct '18

16 Oct '18

Hello all, I have implemented a service in genode os which is based on tz_vmm demo on i.mx53-qsb board. Now I want to measure the execution time of the service. I measure the execution time both in linux and genode,but find a incredible result: 1. In linux, I record the start time t1 and end time t2 ,then I use t2-t1 to measure the execution time. 2. In genode, I get a timer use : Timer::Connection _timer(_env), and use _timer.elapsed_ms() to get the start and the end of the service time and use end-start to calculate the execution time. However, the result of the two world are far from each other. In linux, it's about 45 seconds, but in genode it's only about 11 seconds. I know, in linux side, it will first open the help module in kernel space and issue smc to switch to secure world and switch back when service is done. But I think it won't take such a long time.And actually, I think the execution is about 45 seconds which I observed from the start and end message. So I doubt there's problem with my measurement in genode. My settings: 1. In tz_vmm.run: add targets {drivers/timer} add <start name="timer"> <resource name="RAM" quantum="1M"/> <provides><service name="Timer"/></provides> </start> add boot_modules {timer} 2. In service file , server.cc: add #include <trace/timestamp.h> in funcion add: Timer::Connection _timer(_env); start=_timer.elapsed_ms(); Any help will be grateful, thanks! ------------------ Best wishes
