Further questions

Hi, Thanks you very much for that. I now have it running. I have another question about Genode. More specifically, I was wondering whether any of the Iguana services at all. I ask this given that the weaver.xml file refers to memsections and pds (i'm assuming that means protection domains).

It actually tells you what's wrong. ;-) In the 'weaver.xml' file, there is a memsection referring to a file called 'config'. This is the configuration file of Genode's init process. You can use a copy of the template provided at 'os/config/demo'. You can either specify this file as filename for the 'config' module entry in 'weaver.xml' or copy it to your '<builddir>/bin/' directory (and of course rename it to 'config'). This bit was missing in the Wiki. So I added it to the Wiki page. Thank you for pointing it out.

Adding a new library
by Peter Nguyen 25 Feb '10

25 Feb '10

Hi, I'm now trying to add my own library, and have tried adding the files as part of 'base'. Every time I try to build Genode, i keep getting messages pertaining to undefined references to functions that i have implemented. How do i go about incorporating the files i've written as part of 'base'? I'm sure i've missed something.... Thanks Peter

The new release 10.02 of the Genode OS Framework is available
by Norman Feske 24 Feb '10

24 Feb '10

The release 10.02 again broadens the field of applications for Genode by introducing support for two new kernels: the Codezero kernel and the NOVA hypervisor. The former is primarily targeted at ARM platforms, the latter at x86 virtualization. Moreover, we introduced a management concept for real-time priorities within the framework's API, which can be used in conjunction with the real-time schedulers of the L4ka::Pistachio and OKL4 kernels. Beside many improvements and refinements of the existing parts of the framework, we incorporated the initial port of the Python script interpreter into this release. Release-notes summary for version 10.02 --------------------------------------- * Platform support * NOVA hypervisor * Codezero kernel * New thread-context management * Real-time priorities * Python scripting You can find the complete release notes for the version 10.02 here: http://genode.org/documentation/release-notes/10.02/ The new release is available via the project's subversion repository and at the Genode download page: http://genode.org/download/latest-release Regards -- Norman Feske Genode Labs http://www.genode-labs.com · http://genode.org Genode Labs GmbH · Amtsgericht Dresden · HRB 28424 · Sitz Dresden Geschäftsführer: Dr.-Ing.

Building lwip
by Peter Nguyen 22 Feb '10

22 Feb '10

Hi, I'm trying to build the lwip test so that I can make a start on experimentation. However, I keep on getting build errors. To build this package, I included the libports package, and also the libc package. However, I keep getting errors about how size_t hasn't been declared in scope. I also tried including my own definition for size_t, but other errors result. What is the correct way of building the lwip package? Peter

race in oklinux/contrib/arch/l4/kernel/sys_genode.c
by Sven Fülster 17 Feb '10

17 Feb '10

Hi all, you have a race condition in oklinux/contrib/arch/l4/kernel/sys_genode.c resp. oklx_genode.patch lines 1894..1905 #ifdef CONFIG_FB_GENODE + if(genode_input_initialized()) + { + /* Put the input events into our framebuffer driver */ + num = genode_input_flush(); + for(i=0;i<num;i++) { + genode_input_event(i, genode_fb_mouse_event, genode_fb_key_event); + } + } +#endif //CONFIG_FB_GENODE + + genode_lock(timer_main_kernel_lock); which shows up under heavy load (freezing Xfbdev, raising some BUG()s or a pagefault in update_stats_wait_end). Moving the input polling into the critical section solved the problem here: + genode_lock(timer_main_kernel_lock); + #ifdef CONFIG_FB_GENODE + if(genode_input_initialized()) + { + /* Put the input events into our framebuffer driver */ + num = genode_input_flush(); + for(i=0;i<num;i++) { + genode_input_event(i, genode_fb_mouse_event, genode_fb_key_event); + } + } +#endif //CONFIG_FB_GENODE Cheers Sven -- Sven FÃ¼lster
