IDE Controller Driver Introduction

BSP and Device Driver Development Guide

13.1: Introduction

The IDE Controller driver is responsible for providing an interface to an IDE Controller. The capabilities provided by this driver are:

Read IDE Controller register
Write IDE Controller register
Read data block through IDE Controller Data Register
Write data block through IDE Controller Data Register

The reference implementation for an IDE Controller driver can be found in $RTEMS_SRC_ROOT/c/src/libchip/ide. This driver is based on the libchip concept and allows to work with any of the IDE Controller chips simply by appropriate configuration of BSP. Drivers for a particular IDE Controller chips locate in the following directories: drivers for well-known IDE Controller chips locate into $RTEMS_SRC_ROOT/c/src/libchip/ide, drivers for IDE Controller chips integrated with CPU locate into $RTEMS_SRC_ROOT/c/src/lib/libcpu/myCPU and drivers for custom IDE Controller chips (for example, implemented on FPGA) locate into $RTEMS_SRC_ROOT/c/src/lib/libbsp/myBSP. There is a README file in these directories for each supported IDE Controller chip. Each of these README explains how to configure a BSP for that particular IDE Controller chip.
