Hello, as stated I try to run the Demo on NOVA. I've been following the guide on the homepage and: - prapared the ports for nova and x86emu - prepared libc - uncommented 'REPOSITORIES += $(GENODE_DIR)/repos/libports' in the config file - made the builddirectory - made the kernel - successful run the demo on a Linux Kernel System: I am using Ubuntu 16.04 LTS I am getting the following error output: -------------------------------------------------------------------------------- Program lib/ld/nova/ld-nova make[1]: Verzeichnis â/home/j-r/UNI/genode/build/nova_x86_32â wird verlassen genode build completed using 'core-nova.o' as 'core.o' using 'ld-nova.lib.so' as 'ld.lib.so' using 'nova_timer_drv' as 'timer' install bootloader creating ISO image...

gdb with Qt
by Johannes Kliemann 11 Aug '17

11 Aug '17

Hi, I currently try to debug a Qt application with gdb. I adapted the setup from `ports/run/gdb_monitor_interactive.run?` and tried it with the framebuffer test and tetrix. The framebuffer test worked fine but with tetrix it hangs after the first continue and doesn't seem to break at `binary_ready_hook_for_gdb`. There's also no further output in Genode so I suspect that nothing is executed anymore. This seems only to happen with Qt applications. Did anyone had a similar problem? Regards, Johannes

Error unable to initialize cap quota of PD
by Jörg-Christian Böhme 09 Aug '17

My setup/environment: - Source: Branch: master Date: Thu Jun 29 00:18:26 2017 +0200 commit 0d1be4abe2294155e36bc0eb0c1cd61499f08d93 - Target-genode-System: nova x86_64 - Host-System: genode-x86-gcc (GCC) 6.3.0 Ubuntu 17.04 QEMU emulator version 2.8.0(Debian 1:2.8+dfsg-3ubuntu2.3) Hi @all, I try to run following system scenario: make run/launcher KERNEL=nova but it fails with endless loop of following warning: ... Warning: PD (init -> drivers) cap limit (used=44, limit=46) exceeded during transfer_quota(4) ... I want to fix that and try to understand what is the root cause for this warning. I read the documentation, mainly 6.2.2. Resource assignment -> Capability budget. But I'm not smart enough to understand this ;-), again I'm a newbie :-). Is there some other documentation or another chapter that I should read ? By the way, I read the hole old documentation 16.05 before. What I try/understand: In [BUILD_DIR]/var/run/launcher.run I see following: ... <default caps="50"/> ... <start name="drivers" caps="300"> ... At start time I see following output: ... 5072 MiB RAM and 63254 caps assigned to init ...

ROM: [000000007fe03000,000000007fef5830) usb_drv ... I think the root cause is following Error: [init -> drivers] Error: acpi_drv: unable to initialize cap quota of PD I understand that the acpi_drv component need X caps to transfer to the drivers component. But how many caps ? Then I try to understand the warning for example: [init -> drivers] Warning: ps2_drv: assigned caps (60) exceed available caps (0) What I understand after reading the documentation: ps2_drv try to give the drivers component 60 caps but they have only 0 caps left? Also I try to understand the following warning: Warning: PD (init -> drivers) cap limit (used=44, limit=70) exceeded during transfer_quota(28) I understand: The drivers component used 44 caps. The component need additional caps of 28 but the limit of 70 caps is exceeded. (44 + 28 = 72 > 70) Why limit 70? In the start configuration we set for the drivers component 300 caps. So I read in the documentation, that we can enable a diagnostic mode for the PD session. I try this but even then, I did not understand the logs. Here what I get: ...

PD (init -> drivers) consumed RPC cap (used=7, limit=280) The drivers component create/consumed a RPC cap and after that they used 7 caps with a limit of 280. Again, why the limit is set to 280 and not 300 ? How many caps are needed for the "RPC consumed" ? Because I see also following line: ... PD (init -> drivers) consumed RPC cap (used=39, limit=280) PD (init -> drivers) consumed RPC cap (used=41, limit=280) ... After consumed RPC cap and using of 39 caps, there is additional consumed RPC with a used of 41 ? Why not 40 ? Next confusing lines for me: PD (init -> drivers) transferred 3 caps to 'init' (used=12, limit=277) Drivers transferred 3 caps from the limit of 277 to init? After that we get a limit of 280? PD (init -> drivers) transferred 3 caps to 'init' (used=13, limit=280) etc. I add the full log below. I'm really sure I missed something, but I don't know what. Maybe the root cause is somewhere else. Hopefully somebody give me a hint and/or explain me the log output of "caps" warning. I found the log in the source but even that, I'm not fully understand the purpose of the log.

Blocking wait for interrupt
by Johannes Kliemann 08 Aug '17

08 Aug '17

Hi, I'm currently writing a dde_linux driver that requires to wait for an interrupt to be handled. It basically initializes the hardware and then waits for an event to occur. This event is usually triggered by the interrupt (respectively its handler) which occurs after hardware initialization. My problem is that this interrupt doesn't appear while the function triggering it didn't return. So when this function blocks to wait for the interrupt, a deadlock is created. Besides using the timer I tried to block the execution with a semaphore creating the same problem. Creating an async version is no option due to the architecture of the Linux driver. How are interrupts handled in this case? What causes them to block and how can I work around this? Regards, JK

execution time on RPI.
by Mohammad Hamad 04 Aug '17

04 Aug '17

Hi all, I am trying to measure the execution time of a function on RPI model B. I used the "Trace::timestamp" function to calculate it. In the same time, I used the elapsed_ms() function to compare with it. as I understood, the "Trace::timestamp" function gives the performance counter. Dose the elapsed_ms function provide the execution time of the method in milliseconds? During the measurements, I got some related numbers in somehow. For an example, the average of elapsed_ms() was 2,18 and the average of performance counter is 24825,02 How could I convert the delta of the performance counter to milliseconds? I guess I need to divide by the CPU_cycle. If yes, does the cpu_cycle specified or modified by the Genode? How can I get this value? best,

Nova without Bender
by Johannes Kliemann 04 Aug '17

Hi, I tried to use Nova without Bender with Multiboot2. Basically it works, but when I omit Bender, there's no serial output from either Nova or Genode. I couldn't find out what Bender does different to enable serial on Nova. My grub2.cfg looks as follows: > set timeout=5 > serial --unit=0 --speed=115200 > terminal_output serial console > terminal_input serial console > menuentry 'Genode on NOVA' { > multiboot2 /hypervisor hypervisor iommu serial novpid novga > module2 /image.elf image.elf > } What is missing to enable serial on Nova alone? Regards, Johannes PS: It also seems that Benders Multiboot2-header [1] is not specification conform. The tags type and flags are defined as double word but according to the specification [2] these are u16 so this should be a word only.

Any genodians attending SHA2017?
by Jean-Philippe Ouellet 02 Aug '17

Hello all, Long time lurker, first time poster. I will be attending SHA2017 [1] next week to give a talk about Qubes OS [2]. I see there was at least some mention of SHA among you [3], so perhaps some Genode people plan to attend? I've long been a fan of what Genode is working towards, and I would definitely be interested in exploring the possibility of a collaboration between Genode and Qubes at some point. To be clear, I do not represent Qubes in any official way, and I'm reaching out only as myself. Regards, Jean-Philippe [1]: https://sha2017.org/ [2]: https://www.qubes-os.org/ [3]: https://github.com/genodelabs/genode/issues/1985#issuecomment-290227597

lwip and seL4
by Steven Harp 01 Aug '17

01 Aug '17

Observed a problem testing lwip under seL4 (run/lwip). This succeeds with kernels okl4, foc, and nova, but under seL4 there are complaints from acpi_drv (see below). The "Error: I/O memory [1ffe1000,1ffe2000) not available" seems most concerning. Build architecture is x86_32, relying on drivers dde_ipxe, testing in qemu on Xenial. Theories / workarounds (seL4)? // Steve > [init -> nic_drv] --- iPXE NIC driver started --- > [init -> nic_drv] -- init iPXE NIC > [init -> acpi_drv] Error: ROM-session creation failed (ram_quota=6144, cap_quota=3, label="platform_info") > [init -> acpi_drv] Error: Could not open ROM session for "platform_info" > [init] child "timer" announces service "Timer" > [init] child "acpi_report_rom" announces service "Report" > Warning: void Genode::Rpc_cap_factory::free(Genode::Native_capability) not implemented - resources leaked: 0x10 > [init] child "acpi_report_rom" announces service "ROM" > Error: I/O memory [1ffe1000,1ffe2000) not available > Error: Local MMIO mapping failed! > [init -> acpi_drv] Error: IO_MEM-session creation failed (cap_quota=3, ram_quota=6K, base=0x1ffe1000, size=0x1000, wc=no) > [init -> acpi_drv] Warning: 1 dangling allocation at allocator destruction time > Warning: unmapping of managed dataspaces not yet supported > [init -> acpi_drv] Error: Unknown exception occured - failure > [init -> acpi_drv] Error: __cxa_guard_abort called > Kernel: Thread 'ep' died because of an uncaught exception > [init -> acpi_drv] Error: Uncaught exception of type 'Genode::Service_denied' > [init -> acpi_drv] Warning: abort called - thread: ep > [init] child "acpi_drv" exited with exit value 1 > Error: Test execution timed out > Makefile:309: recipe for target 'run/lwip' failed

Celebrate Genode's 9th anniversary with us!
by Norman Feske 31 Jul '17

31 Jul '17

Dear Genode community, to continue our tradition of celebrating our accomplishments in the form of a seasonal barbecue and camp fire, we invite Genode's friends and community to the banks of the river Elbe in Dresden/Germany. Unlike previous years, which were focused on technical breakthroughs, the leitmotif of the past year was Genode's long-term sustainability, maturity, and scalability. On that account, we streamlined key infra- structure (such as the VFS), and profoundly revisited the framework's architectural foundations and lowest-level protocols. This line of development eventually culminated in the application-binary compatibility across kernels as different as seL4, NOVA, or Linux. The practiced continuity of development was underlined by the third edition of the "Genode Foundations" book. With regard to Genode's role within the open-source community, we had the honor of hosting the microkernel devroom at this year's FOSDEM, and are very happy about the fruitful relationships with sister projects like the Muen separation kernel and the seL4 microkernel community. Business-wise, we are delighted about the growing use of Genode in commercial products, and about Genode's role as the technological basis for entirely new ventures, pursued independent from our company. Let us meet together to celebrate the past, present, and future of our project, and enjoy the get-together of the Genode team and collaborators. We will hold the anniversary party at the river bank of the Elbe: Google Maps: http://goo.gl/maps/C0luj 31st of August, 6 pm near Eisenberger Strasse in Dresden Enjoy the atmosphere at the river bank with tasty barbecue of vegetarian and non-vegetarian food, and a nice selection of beverages! If you are going to attend, please let us know by writing a short note to: info@...1... Cheers Norman -- Dr.-Ing.

Networking Support in VirtualBox
by Chris Rothrock 27 Jul '17

27 Jul '17

I'm working with the VirtualBox run recipe where I have set use_net 1, added the repositories for dde_linux and dde_ipxe for the NIC driver. The build runs successfully and I can boot to the 2 virtual machines (I have one as TinyCore and one as DSL - Damn Small Linux) and interact with the OS's but there is no network adapter detected. To resolve this, I set the Adapter 0 to enabled in the test.vbox file but when I do this, I no longer get any video within the frame for the virtual machine (not even the bootloader for that frame). I have tried increasing the cap for the virtualbox module in the virtualbox.run recipe but still have nothing. I need to be able to test network communication between the two virtual machines (and to the wider network on which they are attached) but this is preventing me from this process. Any help in this would be greatly appreciated. -- Thank You, Chris Rothrock Senior System Administrator (315) 308-1637
