Until now, block drivers had to deal with a pointer to the client session component, e.g.: to acknowledge block packets already processed. When a session was closed, the driver object wasn't informed explicitly, which leads to defensive programming, or lastly to a race-condition in test-blk-srv. To prevent from this class of errors, the pointer is now private to the generic block driver base class, and not accessible to the concrete driver implementation. Moreover, the driver gets explicitly informed when a session got invalidated. Ref #113 |

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.
