The 'Timer::Session::msleep' function is one of the last occurrences of long-blocking RPC calls. Synchronous blocking RPC interfaces turned out to be constant source of trouble and code complexity. I.e., a timer client that also wants to respond to non-timer events was forced to be a multi-threaded process. This patch replaces the blocking 'msleep' call by a mechanism for programming timeouts and receiving wakeup signals in an asynchronous fashion. Thereby signals originating from the timer can be handled along with signals from other signal sources by a single thread. The changed interface has been tested on Linux, L4/Fiasco, OKL4, NOVA, L4ka::Pistachio, Codezero, Fiasco.OC, and hw_pbxa9. Furthermore, this patch adds the timer test to autopilot. Fixes #1
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.
