A Nic::Session client can install a signal handler that is used to propagate changes of the link-state by calling 'link_state_sigh()'. The actual link state is queried via 'link_state()'. The nic-driver interface now provides a Driver_notification callback, which is used to forward link-state changes from the driver to the Nic::Session_component. The following drivers now provide real link state: dde_ipxe, nic_bridge, and usb_drv. Currently, OpenVPN, Linux nic_drv, and lan9118 do not support link state and always report link up. Fixes #1327 |

This is the example operating system based on the Genode OS framework: :_Init_: is the first real process in the system. The provided implementation uses a very simple XML parser to read its configuration files. :_Drivers_: The example OS has basic drivers for frame buffer, mouse and keyboard input, the PCI bus, the real-time clock, and system-specific timers. :_Server_: The only server in the example OS is Nitpicker, a minimal-complexity GUI server. :_Test_: are also part of the example OS. You may have a look at the fork bomb as a simple system stress test. :_Ldso_: is the dynamic linker used for loading executables that are linked against shared libraries. :_Lib_: contains libraries used by the components of the OS repository, in particular the device-driver kit, the alarm framework, and support for dynamic linking.
