This is a first version of the AHCI driver. It supports SATA HDDs with UDMA-133 only, up to 6 Gbps and native command queueing. The more blocks one transfers with one command, the higher is the chance that the driver produces a fatal handshake error. Nevertheless the driver is stable with one block per ATA command. Although NCQ is used the driver doesn't queue multiple commands simultanously. The driver was tested with a western digital HDD "WDC WD2500BEVS-08VAT1 13.01A13" (250 GB) with hw_arndale (run/ahci) and foc_arndale (run/ahci, run/l4linux: dd). SSDs were not tested. Fix #706
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.
