Boot method declaration
by Martin Stein 18 Dec '12

18 Dec '12

By now when doing a build there are two ways of defining the boot method. In 'base-mb' one writes 'RUN_OPT="--target jtag" make demo' or 'RUN_OPT="--target qemu" make demo' while qemu is set by default. At least in base-hw with imx53 one must enrich the SPECS e.g. in etc/specs.mk by the 'uboot' spec to get an appropriate Uboot image. Are there pros or cons for one of these methods, because i would prefer to use only one them.

Cpu session interface num_cpus
by Daniel Waddington 18 Dec '12

Hi, I am trying to use num_cpus as described in release notes 12-11 on Fiasco.OC, but it's not there - it calls the virtual implementation on platform_generic.h returning 1. I am using GIT branch master - should I be using something else? Daniel

l4linux booting failure on Genode
by Jilong Kuang 17 Dec '12

17 Dec '12

Hi, I was trying to run l4linux on Genode following the online tutorials. Compiling was fine. I didnt change any configuration file or script. Everything was in default setting. I failed to boot up the l4linux using either emulators (QEMU, Virtualbox) or a real machine. It just hangs during the boot process and I observed multiple error messages (quota exceeded, illegal announcement of service " Uart", Cannot determine physical address for dataspace Binary! etc). I attached the log file of a typical run on a real machine (Intel Core i7) for your reference. I hope someone could spot some problems in it. Thank you very much! Best regards, Jilong

NOUX limitations
by Daniel Waddington 17 Dec '12

17 Dec '12

Hello there, Can someone explain the current limitations of NOUX? I set up my own NOUX package, then tried to call POSIX sleep and got the error "Invalid attempt to create a thread besides main". Why is this? I also see that pthreads are not functional for NOUX. Is there a specific reason for this? Can you tell me what your roadmap for NOUX is? Best, Daniel

Run two instances of nic_drv
by Ivan Loskutov 13 Dec '12

13 Dec '12

Hi all, I tried to start 2 instances nic_drv. I patched driver for scan next deviceif IO region already mapped and saw second NIC initialisation. But if started two instances nic_drv then driver didn't receive packet from network. I think it caused IRQ handling. How can I solve this issue? Anyone have ideas about it? -- Ivan Loskutov

live CD + Plan 9
by syd bris 04 Dec '12

04 Dec '12

Hi, When do you think the next live CD demo will be available? The Plan 9 Operating System was recently ported to the Raspberry Pi single-board computer. Meanwhile, Genode now works on the Pandaboard single-board computer. Plan 9 is compatable with the Inferno OS, while Genode works with other novel OSs. So, have you ever considered running the Plan 9 Operating System on Genode? Such multi-porting of Plan 9 could act to revitalise this unique OS - and may give Genode a wider audience.
