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.

Question regarding parent capabilities
by Steffen Liebergeld 09 Jun '10

09 Jun '10

Hi, for my porting efforts, I need to map the physical parent Capability into the protection domain of a newly created Child. To do so, I extended the Cpu_session with a method "native_thread", which --given a Genode::Capability-- will tell me the "physical" Capability of a thread. I map the parent capability into a known place of the child address space using the assign_parent method of Platform_pd. Unfortunately at this point I am stuck. Can you give me some advice on where assign_parent is called and how I can provide it with the correct capability (as my tries of implementing that in Process::Process have failed)?

Using the HTTP server via TAP
by Peter Nguyen 03 Jun '10

03 Jun '10

Hi, I was just wondering in using TAP with the HTTP server (and following the instructions in the genode 10.02 documentation), i've noticed that when i have multiple connections to the server, whereby i have a windows xp virtual machine making requests to the server in addition to the host operating system (the XP vm is running in qemu as well as the web server), the IP addresses that the web server obtains are always the same regardless of the machine making the requests. Does anyone know how to provide unique IP addresses for each VM ie. is there an option i can/need to specify when i run qemu? or is there something i have to do with dhcpd3 or the conf,pid or lease files to ensure this functionality. Thanks Peter

Strange behaviour of member addresses
by Steffen Liebergeld 01 Jun '10

01 Jun '10

Hi, I am experiencing some strange behaviour in genode. In base/include/base/heap.h I placed debug output in the Heap::Heap constructor: Heap(Ram_session *ram_session, Rm_session *rm_session, size_t quota_limit = UNLIMITED, void *static_addr = 0, size_t static_size = 0) : _ds_pool(ram_session, rm_session), _quota_limit(quota_limit), _quota_used(0), _chunk_size(MIN_CHUNK_SIZE) { PDBG("quota_limit=%d this=0x%p &_quota_limit=0x%p", _quota_limit, (void*)this, &_quota_limit); enter_kdebug("quota_limit"); if (static_addr) _alloc.add_range((addr_t)static_addr, static_size); } This prints the following: quota_limit=-1 this=0x1851d8 &_quota_limit=0x185630 Then I placed some debug output in base/src/base/heap/heap.cc:alloc bool Heap::alloc(size_t size, void **out_addr) { /* serialize access of heap functions */ Lock::Guard lock_guard(_lock); PDBG("size=%d _quota_used=%d _quota_limit=%d *this=0x%p &_quota_limit=0x%p", size, _quota_used, _quota_limit, (void*)this, &_quota_limit); And this prints the following: _quota_limit=0 *this=0x1851d8 &_quota_limit=0x18563c Seems to me like the compiler did not correctly calculate the member addresses (this problem appears to be the same that caused the previous error I posted). Do you have an idea why that happened and how to fix it? Mand thanks in advance, Steffen Liebergeld -- Dipl.-Inf.
