FreeBSD The Power to Serve

FreeBSD/ia64 5.2.1-RELEASE Hardware Notes

The FreeBSD Documentation Project

This is a preliminary document. It is incomplete, and in need of additional content. Please send additional information on IA-64 processors, motherboards, and various devices working on FreeBSD to the FreeBSD IA64 porting mailing list.

1 Introduction

This document contains the hardware compatibility notes for FreeBSD 5.2.1-RELEASE on the IA-64 hardware platform (also referred to as FreeBSD/ia64 5.2.1-RELEASE). It lists devices known to work on this platform, as well as some notes on boot-time kernel customization that may be useful when attempting to configure support for new devices.

Note: This document includes information specific to the IA-64 hardware platform. Versions of the hardware compatibility notes for other architectures will differ in some details.

More information on FreeBSD/ia64 is contained on the FreeBSD/ia64 Project page.

2 Supported Processors and Motherboards

Currently supported processors are the Itanium and the Itanium 2.

Supported chipsets include:

  • HP zx1 (only on development branch, see the Perforce repository)

  • HP i2000

  • Intel 460GX

  • Intel E8870

Both Uniprocessor (UP) and Symmetric Multi-processor (SMP) configurations are under active development. At this time, SMP-enabled systems are considered less stable. The current priorities are UP fixes to improve stability.

2.1 Supported Devices Overview

This section contains additional information about what devices may or may not be supported by FreeBSD/ia64.

Except for the PC chipset embedded ata(4) controllers, most should work out of the box. Eventually, all ia64-compatible ATA controllers are expected to be fully supported. Refer to the following sections for various disk controllers and their current status.

In general, ``PC standard'' serial ports supported by the sio(4) driver are expected to work on Intel legacy machines, but not PA legacy machines. The reason is that all devices on HP machines are memory-mapped and there is no ISA device support other than the PCI dictated VGA legacy.

In addition to sio(4) devices, the following devices fail on non-Intel legacy machines (but should work on boxes with an Intel legacy) because their drivers make ISA-specific assumptions that do not hold:

sio(4) No support for memory-mapped I/O
syscons(4) Expect BIOS, VGA probes, etc.
pcm(4) Probes MSS ISA ports ad nauseum
atkbd(4), psm(4) Fixed ISA port locations

3 Supported Devices

$FreeBSD: src/release/doc/en_US.ISO8859-1/hardware/common/dev.sgml,v 1.209 2003/12/07 00:54:22 bmah Exp $

This section describes the devices currently known to be supported by with FreeBSD on the IA-64 platform. Other configurations may also work, but simply have not been tested yet. Feedback, updates, and corrections to this list are encouraged.

Where possible, the drivers applicable to each device or class of devices is listed. If the driver in question has a manual page in the FreeBSD base distribution (most should), it is referenced here. Information on specific models of supported devices, controllers, etc. can be found in the manual pages.

Note: Lists of specific, supported devices are gradually being removed from this document in order to reduce the amount of duplicated (and potentially out-of-date) information contained within. When this process is complete, the manual page for each driver should be consulted for the authoritative list of devices supported that particular driver.
