Re: Genode Hack'n Hike 2013
by Norman Feske 23 Mar '15

23 Mar '15

Hello everyone, the date for this year's Genode Hack'n Hike held during 11-16 of September is approaching. Genode's developers will spend those days in the beautiful scenery of the Bohemian Switzerland, relaxing, hiking, and hacking on fun side projects. The Hack'n Hike will be the perfect setting for getting involved with the community, catching up, or just hanging out with the Genode crowd. There is still room for more participants. Genode Labs sponsors the event. So your participation/accommodation is free. If you like to join in, please get in touch by writing to hacknhike@...1... or commenting on https://github.com/genodelabs/genode/issues/793.

Re: Porting on i.MX6
by Aditya Kousik 23 Dec '13

23 Dec '13

Hello Firstly, thank you for patiently replying to our queries and debugging issues so far. We're trying to port Genode onto an i.MX6, which we've realised is no easy task. Our initial approach to this was to tweak existing i.Mx53 files and make corresponding changes (arm cortex a9, created imx6 related folders in include). As pointed out to us by Stefan, this was completely off track as the memory layout may be mixed up (or many more issues). Here's a brief reboot of our attempt: 1. edit create_builddir to add a rule for imx6 board and added build.conf.hw_imx6 in builddir folder. 2. modify board_base.h in base/include/platform/imx6/drivers and fill with addresses by referring to the imx6 reference manual. (We also added CORTEX_A9_CLOCK and private memory base) 3. read through the Makefile and added spec-hw_imx6 and spec-platform_imx6 respectively. 4. created imx6 folder with files in os/include/platform/imx6 as well. (All with imx53 as reference) Make: Since the drivers for imx6 would take a long time to code, we are NOT running demo.run. We tried to build hello.run (without building drivers/timer) according the instructions given in your site. We're getting the following error: Program core/imx6/core COMPILE _main.o ASSEMBLE boot_modules.o COMPILE console.o COMPILE context_area.o COMPILE cpu_session_component.o COMPILE cpu_session_support.o ASSEMBLE crt0.o COMPILE dataspace_component.o COMPILE dump_alloc.o COMPILE io_mem_session_component.o COMPILE io_mem_session_support.o COMPILE irq_session_component.o COMPILE kernel.o COMPILE kernel_support.o COMPILE main.o make[3]: *** No rule to make target `mode_transition.o', needed by `core'.

Writing Pin-muxing registers in an am3359.
by Bob Stewart 05 Nov '13

05 Nov '13

On a TI am3359 processor (Beaglebone Black) I'm attempting to attempting to control the GPIO pin-muxing through the Control subsystem registers which start at 0x4e100000. I can read and write to the GPIO0 through GPIO3 registers correctly through MMIO after attaching the device memory, but when I try to write to any of the pin mux registers nothing is written and no errors are output. The code I've written to set up pin muxing resides in a gpio driver which is a modified version of an am 33xx gpio driver I pulled from the ksyslabs.org repository. With verbosity turned on, I see the that the pin mux registers are attached to local memory: /Genode::Io_mem_session_component::Dataspace_attr Genode::Io_mem_session_component::_prepare_io_mem(const char*, Genode::Range_allocator*): I/O mem [44e10000,44e11000)// //[init -> gpio_drv] GPIO_control base is 0x44e10000 local is 0x4000/ I write a value of 5 to the register offset 0x800 into the Control dataspace: /[init -> gpio_drv] mmio write 0x4800: 0x00000005// //[init -> gpio_drv] void Omap_driver::set_pin_controls(int, int, int): B=1, P=0, Mode=5, Input=0, Offset=0/ In jdb I see that the value at 0x4800 has not changed after apparently writing 5 to it. I believe I've set up the IO memory mapping correctly, the values read from the pin muxing registers look correct, and the GPIO subsystem appears to be set up correctly as I can turn on and off some LEDs. Is there something I need to do to enable writing to the memory region containing the Control registers? Thanks for any help. Bob Stewart

Choosing a Kernel
by Neal H. Walfield 05 Nov '13

05 Nov '13

Hi, I'm looking to run Genode on an ARM Cortex A8. I'm primarily interested in the security properties of the resulting system. I'm explicitly not interested in running multiple OS personalities or doing virtualization. What I do want is as pure an object capability system as possible and as small an attack surface as possible. This seems to suggest Fiasco.OC or OKL4, but perhaps the bare hardware kernel is better. I think NOVA doesn't come into question, because it only runs on x86. I couldn't find much information about the bare hardware kernel. I'd appreciate any pointers. Thanks! :) Neal

Question about system architecture, noux and interprocess communication
by J.M. Becker 01 Nov '13

01 Nov '13

First I wanted to say, I've been following Genode for about a year and I'm very excited about its progress. My question has to do with Noux and how communication is done between processes, and the eventual porting of D-Bus. I'm unsure about just how isolated each noux process is, from other noux processes, and how something like d-bus could share information between running processes. In addition does each process always execute in it's own noux? and if so how could something like a ps command get information about all running processes? I'm just trying to get a handle of things before jumping in and attempting to port additional components. Thank you, -J.

Booting option
by GANESH MALOTH 30 Oct '13

30 Oct '13

I want to boot my system with genode-2010-11.iso file(To check live CD demonstration). I first did it in virtual box, i got booted. Now i want to check with realistic booting. I have burnt cd using this iso file, followed instructions in genode.org about system configuration check up and all, and then gave boot options : Boot with cd-dvd and saved but i am not able to boot. Can somebody suggest me some options for it? Maloth Naresh IITM

PCI passthrough in vancouver
by Salscheider, Niels Ole 23 Oct '13

23 Oct '13

Hello, I am trying to implement PCI passthrough in vancouver when using NOVA. For PCI passthrough, I have to handle MessageHostOp::OP_ATTACH_MSI (amongst others). This requires modifications to the Irq_connection / Irq_session. My current plan is to pass the bdf value through to the Irq_proxy_component, where I can use it to get the pci config space. This is then passed to the assign_gsi syscall. Apart from that, I have added two functions to read back the msi address and data. However, my current implementation hangs when I try to get the first device from a Pci::Connection in Irq_proxy_component. Does it make sense to pass the bdf value to the Irq_proxy_component or would you suggest another way to design the Irq_connection interface?
