SGI-575 platform software user guide
====================================

.. contents::


Introduction
------------

SGI (System Guidance for Infrastructure) is a collection of resources to provide
a representative view of typical compute subsystems that can be designed and
implemented using specific generations of Arm IP. SGI-575 in particular is based
on the following hardware configuration.

- 8x Cortex-A75 with private L2 Cache
- DynamIQ with L3 Cache options
- System Level Cache options
- Up to 2x DDR4-3200 (DMC-620)
- Arm Cortex-M7 for System Control Processor (SCP) and
  Manageability Control Processor (MCP)

This document is a user guide on how to setup, build and run the SGI-575
software stack on the Fixed Virtual Platform.


Setting up the Host Machine and downloading the software stack
--------------------------------------------------------------

Host Machine requirements and the necessary steps to be followed to sync the
software stack are listed on '`Download sources`_' page.
