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.


Obtaining the SGI-575 Fast Model
--------------------------------

The latest version of SGI-575 Fast Model can be requested by sending a email
to Arm at this email address: `support-connect@arm.com <mailto:support-connect@arm.com>`_.

Follow the instruction in the installer and setup the FVP. Typically, the
installer will ask to create a new folder in the home directory. You can either
install the FVP in the home folder, or in the ``fastmodel/refinfra`` folder
inside the workspace. If you would like to install in the ``fastmodel/refinfra``
folder, when asked for the install location, provide the absolute path of the
``fastmodel/refinfra``.


Supported features
------------------

SGI-575 platform software stack supports the following features.

- `Busybox Boot`_
- `Buildroot Boot`_
- `Linux Distribution Boot`_
- `UEFI Secure Boot`_
- `DMC-620 RAS`_

Follow the links above for detailed information about the build and execute
steps for each of the supported features.


Release Tags
------------

Table below lists the release tags for the SGI-575 platform software stack and
the corresponding SGI-575 FVP version that is recommended to be used along
with the listed release tag. The summary of the changes introduced and tests
validated in each release is listed in `change log`_.
