README

This directory contains an implementation of a simple AHCI driver.

Behavior
--------

The server implements Genode's new block-driver API ('os/include/block'), thus
exposing the block-session interface as front-end. AHCI depends on Genode's PCI
driver as well as the timer server. For a usage example see: 'os/run/ahci.run'.

Limitations and known issues
----------------------------

Currently, the server scans the PCI bus at startup and retrieves the first available
AHCI controller, scans the controller ports and uses the first non-ATAPI port
where a device is present.

On real hardware and on kernels taking advantage of I/O APICs (namely NOVA and
Fiasco.OC) we still lack support for ACPI parsing and thus for interrupts,
leading to a non-working driver.
