Dear Adam : Thank you very much ! Now I have understand the IO MAPPING rules . All IO address mapping is only recognized by first 5 bits ,the last three bit is no mean for address(only for flags) . I mapping the S3C6410 GPIO ,Video-control ,Sfr once again . Now i can make the LCD bright and run the spectrum in real hardware . Thanks .

I objdump the image, and did not found that address. However, we can't get more info in dump file because the file didn't include any symbol table(Can we dump the symbol table by adding some compile option? ). At last, different from other chip, we found that address e0000000-fb000000 in s5pv210 is some important register, and the kernel seem to map that address, it doesn't matter?

FYI: Visions on Genode OS development
by Christian Helmuth 18 Feb '13

18 Feb '13

Hello L4 hackers, this morning I stumled upon a blog posting http://allsoftwaresucks.blogspot.de/2013/02/visions-on-genode-os-developmen… by Alexander Tarasikov, who also comments on "L4Linux issues" in the last section of the posting. IMO he addresses an important point that is also sporadically asked on this mailing list: Beside the technical issues with SVN and Git, how open is the development of L4Linux, L4Re etc. and what could we expect from it? Will it walk an community-relared open path in the future? I'd by very glad to hear some words about this from the current developers. Thanks -- Christian Helmuth Genode Labs http://www.genode-labs.com/ · http://genode.org/ https://twitter.com/GenodeLabs · /ˈdʒiː.nəʊd/ Genode Labs GmbH · Amtsgericht Dresden · HRB 28424 · Sitz Dresden Geschäftsführer: Dr.-Ing.

Using l4re in loadable modules of L4Linux
by Haohui Mai 12 Feb '13

12 Feb '13

Hi folks, I'm building a loadable module of L4Linux. The module calls l4re_rm_alloc() / l4re_rm_attach() to allocate shared memory. Because the symbols l4re_rm_attach_srv / l4re_utils_cap_alloc / l4re_ma_alloc_srv are not exported to the modules, I exported them using EXPORT_SYMBOL(). The module, however, still fails to load, complaining about that these symbols cannot be found. Is there a way to export these symbols so that loadable modules can use L4Re? Thanks very much! ~Haohui

Debug: how to enumerate all kernel objects
by Евгений Федотов 07 Feb '13

07 Feb '13

Hello, L4 Hackers! My question is: How to retrieve all kernel object list (threads, tasks, IRQs, Gates) in non-interactive way? Since Fiasco JDB stores the full list of objects, is there any l4_invoke_debugger call to retrieve object information from order number or ID? Best regards, Eugene.

Hello, L4 Hackers! From JDB manual I found that JDB supports non-interactive commands such as: enter_kdebug("*#I*IR+"); //enable IPC logging Does it work in other than x86 architectures, e.g.. Fiasco on ARM? Best regards, Eugene.
