Kernel and Hardware Services Quick Start

Architecture

For architectural details please see the documentation for each component.

Getting started with Kernel and Hardware Services

The kernel is designed to simplify porting. This means it has been designed in such a way as to make it easy to identify the various parts of the layered kernel stack that require porting for delivery to specific hardware.

Kernel and Hardware Services provides:

• A multi-tasking, real-time operating system kernel. This creates and manages the primary OS kernel abstractions, such as processes, memory management, and scheduling.

• Device drivers that provide logical interfaces to device hardware.

• Access to and management of file systems.

The documentation provides separate guides for:

• Creators of applications and system services that use the services that the Kernel and Hardware Services components provide.

  • Managing basic system functions

  • Data Management

  • Memory management

  • Configuring locale settings

  • APIS for working with:

    • arrays

    • strings

    • maths

• Creators of new device drivers, for licensees and partners who need to support new hardware devices.

  • Accessing Hardware

• Creators of base ports, who need to configure and extend the Kernel and Hardware Services software to run on new phone hardware.

  • Accessing files on a specific file system
