Hi all,
sorry that I must repeat bothering you :)
I've now set up Genode on the OKL4 kernel for use on my Intel Atom hardware, and I see that sometime during the startup process, the pci-driver is kicked due to an error I don't understand:
-- [init -> test-dde_linux26_usbhid] Initializing DDE Linux 2.6 pa ge cache
Genode::Io_port_session_component::Io_port_session_component(Genode::Ran ge_allocator*, const char*): I/O port [cfc,d00) not available
That means the I/O port 'cfc' requested by the pci-driver is already in use by another component. Therefore, an exception is raised but not caught and you get all these subsequent error messages.
Maybe, your vesa-card's code used that port already?
Please instrument the function: 'static FB_Port* get_port(unsigned short port)' in file 'os/src/drivers/framebuffer/vesa/ifx86emu.cc', to check out who else wants to use that port, e.g. by jumping into the kernel debugger, when someone requested port 'cfc' and looking who's blocking on the active thread - the thread, that fulfills the port request.
Best regards Stefan

Do you have any idea what's missing in my setup?
Thanx in advance
