The ATI RADEON 7500 PCI graphics controller has a standard 15-pin VGA connector, a DVI-I

connector and an S-Video connector. The S-Video functionality is not supported by either OpenVMS or

HP-UX. There is no VGA switch; VGA functions are automatically configured through the console

firmware and software.

DVI-I to VGA Connector Adaptor

OpenVMS does not support direct DVI to DVI operation on the ATI RADEON 7500 card. The DVI port

is only useable by using a DVI to analog (VGA) adapter or cable (this part was supplied on the

AlphaServer version of the card, but is not supplied for HP Itanium). If a DVI to analog adapter or

cable is used, OpenVMS drives both the VGA and DVI interface with the same image.

HP-UX does support all video connections, including direct DVI to DVI, DVI to analog (VGA) and VGA

to VGA.

3 HP OpenVMS I64 – Graphics Software

Installation and Customization

This chapter provides information for installing and modifying the software required to support 2D and

3D graphics with the ATI RADEON 7500 PCI graphics controller under the HP OpenVMS I64

operating system.

The ATI RADEON 7500 PCI graphics controller is directly supported by OpenVMS I64 without

additional software. Bug fixes and new feature support are supplied using the standard OpenVMS

downloadable patch support mechanism, and with new versions of the Operating System.

The behavior of the ATI RADEON 7500 PCI graphics controller’s support software may be modified

after installation on OpenVMS by editing the appropriate files and issuing DCL commands (see

“Multiple Graphics Cards Support” on page 10).

Video Resolutions Supported

The ATI RADEON 7500 PCI graphics controller is capable of supporting the graphics resolutions, color

depths, and refresh rates shown in Table 3-1:

The video mode chosen should match your monitor’s capabilities. In general, refresh rates below 70 Hz

are discouraged on CRT monitors, as they tend to show flicker based on the lighting source and

surrounding equipment. Flat Panel displays generally prefer a 60Hz refresh rate.

The available resolutions are monitor dependent.

The default video mode is 1024X768 @70HZ and 24 bits per pixel depth.

HP OpenVMS I64 – Graphics Software Installation & Customization

ATI RADEON 7500 PCI Graphics Controller Installation Guide

Restrictions, Limitations and Defaults

This section of the document contains limitations, restrictions and defaults for the ATI RADEON 7500

hardware and software.

Minimum Console Revision

The minimum console firmware version for support of the ATI RADEON 7500 graphics controller

under OpenVMS I64 is system dependent. Please consult your platform option information for

minimum requirements.

No VGA Console Support

The initial OpenVMS I64 production release (V8.2) does not support the use of a graphics card (VGA

mode) as a console terminal device. This is expected to be allowed in a subsequent release. A serial line

console, or other Management Processor attached device is required.

HP Integrity Platform Slot Restrictions

The Version V8.2 release of OpenVMS supports three HP Itanium platform types: The RX1600,

RX2600 and RX4640 (along with speed and CPU variants). The following are the known restrictions on

populating slots with ATI RADEON 7500 cards:

•

RX1600 – Only one slot (the top slot) allows an ATI RADEON 7500 card, the bottom slot is

mechanically obstructed. Do not attempt to force a card into the lower slot.

RX2600 – No restrictions. Up to four ATI RADEON 7500 cards may be placed in any of the

slots.

RX4640 – Up to 4 ATI RADEON 7500 cards may be used, with restrictions on the use of slots 3

and 4, and 5 and 6:

One card in slot 3 or 4, but not both

One card in slot 5 or 6, but not both

One card in slot 7

One card in slot 8

If ATI RADEON 7500 cards are plugged into slot 3 and 4, or 5 and 6, the following error

message may be displayed during system startup, and the system will not function correctly:

WARNING[2]: Insufficient resources to assign one or more I/O devices

Default Depth (24 Bits Per Pixel)

OpenVMS has traditionally set the default pixel depth to 8 bits per pixel on 2D graphics options, and

24 bits per pixel on 3D options. With the expanding use of applications such as MOZILLA and

increased use of various types of images such as GIF and JPEG, the default depth for both 2D and 3D

has been changed to 24 bits per pixel.

NOTE: Many older applications may assume a specific depth and visual type – in particular 8 bits per

pixel and PsuedoColor. If your graphics application or a utility depends upon the depth, you

can either modify the application, or change the default pixel depth. For example, the PAINT

program which ships on DECwindows Motif currently only support 8 bits per pixel.

For instructions on changing the pixel depth, see “Overriding the Default Settings” on page 11.

HP OpenVMS I64 – Graphics Software Installation & Customization

ATI RADEON 7500 PCI Graphics Controller Installation Guide

Multiple Colormaps (8 Bits Per Pixel)

Multiple colormaps are not supported by the hardware. The ATI RADEON 7500 PCI graphics

controllers support only one installed colormap at one time. Exceeding this limit in 8 bits per pixel

depth, may cause colormap ‘flashing’, also known as "Technicolor".

Applications should not install or de-install colormaps themselves. The window manager should

perform these actions. However, the application is responsible for providing the window manager with

hints as to which colormaps to install or de-install.

Single Pixel Depth (No Mixed Depth Windows)

Some workstation 3D graphics options in the past provided the ability to mix windows of different pixel

depths on the same screen. The ATI RADEON 7500 board can only support a single pixel depth at a

time. This means that all windows on a specific screen must all have the same pixel depth (no mixed

depth windows).

Visual Types

A visual type defines how the X11 server interprets the contents of a pixel. While the ATI RADEON

7500 hardware only supports a single pixel format at a time, the X11 server can emulate various visual

types depending on the pixel depth. For example, when using 24 bits per pixel both DirectColor and

TrueColor can be used, and at 8 bits per pixel all visual types are available.

The default visual types are: TrueColor for 16 and 24 bits per pixel, and PseudoColor for 8 bits per

pixel.

For information on changing the default visual, see “Overriding the Default Settings” on page 11.

PCI Bus Performance Under Load

Under heavy load - typically mixed high output 2D and 3D - the RADEON 7500 may consume too much

bus bandwidth, and has been observed to sometimes hang the graphics output. The DMA fetch size can

be adjusted to use less bandwidth, at the cost of performance (typically 3D performance).

To reduce the DMA fetch size, modify DECW$PRIVATE_SERVER_SETUP.COM to include the line:

$ DEFINE/SYSTEM DECW$RADEON_FAST_DMA 0

This can be set to the values 0-2, where 0 is the lowest DMA fetch size. The default on Itanium systems

is fast (2).

Open3D Support

The ATI RADEON 7500 supports hardware accelerated 3D support when the pixel depth is set to 24

bits per pixel. Hardware 3D drawing is not available when using 8 or 16 bits per pixel.

Previous versions of OpenVMS provided hardware accelerated 3D graphics and an OpenGL compatible

programming interface for selected option cards through the Open3D license. Starting with OpenVMS

V8.2 on both Alpha and I64 systems, the Open3D license will no longer be required for 3D operation

(for POWERSTORM 300 and 350, and ATI RADEON 7000 and 7500 graphics controllers). The license

for use of 3D is included as part of the base Operating System.

The OpenVMS ATI RADEON 7500 graphics support includes a Mesa3D based graphics library

providing an OpenGL V1.2 compatible programming interface, and GLX V1.2. Among other features,

Chapter 3

HP OpenVMS I64 – Graphics Software Installation & Customization

ATI RADEON 7500 PCI Graphics Controller Installation Guide

the libraries provide support for the ATI RADEON 7500 TCL hardware, hardware alpha and stencil

planes, 3D multi-texturing, and 3D cube map textures.

The RADEON 7500 Mesa3D software will, by default, force a direct-rendered 3D context whenever the

3D client requests connection to the X11 server using the LOCAL transport. Direct rendering is a

highly desirable performance feature for 3D applications.

You can override this default behavior and force the default to always be indirect rendering (indirect

rendering means that all 3D operations are executed by the X11 OpenGL server extension) by defining

the following logical name before running the 3D application:

$ DEFINE LIBGL_ALWAYS_INDIRECT 1

This can also be achieved by using the DECNET or TCPIP transports.

Hardware acceleration can be disabled entirely by defining the system logical:

$ DEFINE/SYSTEM/NOLOG DECW$SERVER_NOACCEL TRUE

HP recommends that the direct rendering interface be used for 3D operation.

Transformation, Clipping and Lighting Support

The Mesa3D driver for the RADEON 7500 contains support for the on-board transformation, clipping,

and lighting (TCL) hardware of the RADEON 7500 for increased primitive rendering performance.

The embedded graphics typically found on HP Integrity systems is based on the ATI RADEON 7000,

and also provides 3D capability, but does not have TCL hardware capability.

Threads Restriction

The RADEON 7500 Mesa3D library for OpenVMS is not thread safe. However, Mesa3D can be used in

a multithreaded program if the use of Mesa3D is restricted to a single thread within the program.

No Backing Store/Save Under for 3D Windows

Backing store and save under features are not supported when 3D is in use.

Multiple Graphics Cards Support

The ATI RADEON 7500 software has been tested for up to 4 cards per system. All operations, including

hardware accelerated 3D graphics, are supported on every card in the system. Consult your Integrity

system options documentation for detailed information on number of cards supported and configuration

limitations.

The embedded graphics available on most HP Integrity systems based on the ATI RADEON 7000 is

compatible with multi-head operation with the ATI RADEON 7500 option card, and can be combined

when using multi-head operation.

Multi-Screen Versus XINERAMA

By default, multiple screens are handled as traditional X11 multiple screens. However, the screens can

be handled as a single “virtual” screen using the XINERAMA extension. This is documented both in the

DECW$PRIVATE_SERVER_SETUP.COM procedure, and in the Motif documentation.

NOTE: Only 2D operation is possible when using XINERAMA. 3D operation will not function

correctly, or will use software only (no acceleration).

ATI RADEON 7500 PCI Graphics Controller Installation Guide

Screen Order and Forcing Single Headed Operation

Screen order is determined by the bus ordering of devices, and will vary across platforms. The

DECW$PRIVATE_SERVER_SETUP.COM file allows the user to override the ordering of screens, or to

force single headed operation. See the documentation in the file, and in the Motif documentation for

more information. For example, to force a specific graphics option to be used in single head mode (in

this case GHB0), add the line:

$ DEFINE/SYSTEM/NOLOG DECW$PRIMARY_DEVICE “GHB0”

Modifying the Graphics Configuration

ATI RADEON 7500 Default Graphics Settings

The default graphics resolution is 1024 x 768. The default refresh rate is 70 Hz. The default pixel depth

is 24 bits per pixel and the default visual type is TrueColor.

Determining Current Settings

To find the current settings under OpenVMS, issue the following commands, in order, at the DCL

prompt:

$ @decw$utils:decw$define_utils

$ xdpyinfo

In addition, you can show the following logical names at the DCL prompt:

$ SHOW LOGICAL/SYSTEM DECW$SERVER_PIXEL_DEPTH

$ SHOW LOGICAL/SYSTEM DECW$SERVER_REFRESH_RATE

$ SHOW LOGICAL/TABLE=DECW$SERVER* DECW$XSIZE_IN_PIXELS

$ SHOW LOGICAL/TABLE=DECW$SERVER* DECW$YSIZE_IN_PIXELS

$ SHOW LOGICAL/TAB=DECW$SERVER* DECW$SERVER_DEFAULT_VISUAL_CLASS

If any logical name is not defined, then the respective default is in effect.

You can also confirm the settings and any errors in the setup by examining the server error log file:

$ TYPE SYS$MANAGER:DECW$SERVER_0_ERROR.LOG

Overriding the Default Settings

The SYS$MANAGER:DECW$PRIVATE_SERVER_SETUP.COM procedure contains

documentation for many of the default X11 server settings that may be changed. For more information

on making changes to the default settings, symbols, and system-wide logical names, refer to the

manual titled Managing DECwindows Motif for OpenVMS Systems. An online version of this document

is available at:

http://h71000.www7.hp.com/DOC/73final/6300/6300PRO.HTML

A complete list of available DECwindows Motif V1.3-1 documentation is available at:

http://h71000.www7.hp.com/DOC/decwin131.html

For newer releases of documentation, check the main HP OpenVMS Systems Documentation

site at:

http://h71000.www7.hp.com/doc/index.html

OpenVMS Alpha and I64 use the same implementation of X11 and Motif and documentation for

one generally applies to the other, unless otherwise noted.

HP OpenVMS I64 – Graphics Software Installation & Customization

ATI RADEON 7500 PCI Graphics Controller Installation Guide

To override the default settings, follow these steps:

1. Copy or rename the SYS$MANAGER:DECW$PRIVATE_SERVER_SETUP.TEMPLATE file to

create a new command (.com) file called DECW$PRIVATE_SERVER_SETUP.COM.

2. Now make the edits for the settings you want to change using a text editor, and save the file.

3. For the changes to take effect immediately you must restart the X server so that the new command

file and changed settings will be used. The command to do this is as follows:

$ @SYS$MANAGER:DECW$STARTUP RESTART

The new file settings will now override the original default settings.

NOTE: By renaming this template file to .COM you will enable multi-head operation. Many HP

Integrity servers provide an embedded graphics option (currently based on the ATI RADEON

7000). The order of the screens is based on the bus order of the options, and will vary based on

platform. See “Restrictions, Limitations and Defaults” on page 8 for information and

restrictions on configuring multiple heads. See “Screen Order and Forcing Single Headed

Operation” on page 11 for information on how to force single headed operation.

Additional system logical names are described in

SYS$MANAGER:DECW$DEVICE_CONFIG_GH.COM

However, this file should not be modified. If you wish to make changes to the default logical names,

redefine them in the DECW$PRIVATE_SERVER_SETUP.COM file. These changes will supersede the

values assigned in the device configuration file.

Many common items are changed by symbolic values in this file, however items are graphics card

specific, and are modified by defining system logical names. The settings include the following items:

DECW$XSIZE_IN_PIXELS

DECW$YSIZE_IN_PIXELS

DECW$SERVER_REFRESH_RATE

DECW$SERVER_PIXEL_DEPTH

For example, to change the default settings from 1024x768, 24 bits per pixel and 70Hz to 1280x1024, 8

bits per pixel and 60Hz:

$ DEFINE/SYSTEM/EXEC/NOLOG DECW$XSIZE_IN_PIXELS 1280

$ DEFINE/SYSTEM/EXEC/NOLOG DECW$YSIZE_IN_PIXELS 1024

$ DEFINE/SYSTEM/EXEC/NOLOG DECW$SERVER_PIXEL_DEPTH 8

$ DEFINE/SYSTEM/EXEC/NOLOG DECW$SERVER_REFRESH_RATE 60

Note that all of these logical names can also be specified as a comma separated list of values. A single

value will be applied to all screens. If a list of values is provided they are applied to the individual

screens in order starting at screen 0.

Note that the visual class automatically defaults to PseudoColor at the 8 depth, which is generally

what most users want. To change the visual type to TrueColor for example, add:

$ DECW$SERVER_DEFAULT_VISUAL_CLASS == 4

Server Startup and Configuration Messages

Server messages are typically logged to the DECW$SERVER_0_ERROR.LOGfile located in the

SYS$MANAGERdirectory. When having problems during setting up the X11 server defaults, or when a

problem is encountered during normal use, be sure to check this file first for messages.

4 HP-UX Configuration

This chapter describes how to configure the ATI RADEON 7500 graphics controller in a system

running the HP-UX operating system.

NOTE: Chapter 4 pertains to the HP-UX operating system only; if you are running the OpenVMS

operating system, see Chapter 3

The examples in this manual show version numbers applicable at publication. To determine

the most recent version of the operating system or video driver, refer to the Release Notes on

the CD-ROM or on the Web at www.hp.com.

Verification of Software Installation

To use the ATI RADEON 7500 graphics controller, you must have installed the Xserver fileset with a

patch version of PHSS_31252 or later. To check the patch version, run the following command:

swlist –l patch | grep Xserver cumulative patch

The output will look similar to this output:

# PHSS_31252

B.11.23.12 Xserver cumulative patch

The patch version will have a format of PHSS_?????, where ????? is the patch number. If this version is

equal or greater than PHSS_31252, the system is ready to use the ATI RADEON 7500. If the patch

version is less than PHSS_31252, install the latest Xserver patch.

1. Log into the HP patch catalog. The URL is www2.itrc.hp.com/service/patch/mainPage.do

2. Go to the find a specific patch search, enter PHSS_31252and press Enter. This brings up a new

screen. If there is a newer patch that supersedes this patch, it will be listed under the Most

Recent heading. You will need to download the newest patch.

3. Click in the box next to the patch and click the add to selected patch list button. This brings up a

new screen that displays the patch along with any other dependent patches.

4. Click the download selected button. This brings up a new screen.

5. Choose the server to use and the format of the patch bundle. Once these options are chosen,

click the download button.

6. This downloads the patch bundle to your system. Save the patch bundle to a convenient place

on your system. For this example, we will assume the patch bundle is downloaded into the

/tmp/PHSS_31252 directory.

7. Once the patch bundle is downloaded, unzip/gunzip/tar the patch bundle depending on the

format of the patch bundle. This extracts the patch bundle. Each bundle is a shar file. To create

a depot for loading, run the create_depot_hp-ux_11 script as root. This creates a bundle in

/tmp/PHSS_31252/depot.

8. As root, run the swinstallcommand using the newly created bundle.

swinstall –s /tmp/PHSS_31252/depot

Restrictions and Limitations

This section provides information on the limitations and restrictions of the ATI RADEON 7500

hardware and software.

No Accelerated 3D Support

The ATI RADEON 7500 graphics controller does not support accelerated 3D (e.g. OpenGL).

Minimum Console Revision

The minimum firmware version for ATI RADEON 7500 graphics controller single head support is V1.0

on HP Itanium Integrity systems.

Multiple Colormaps

Multiple colormaps are not supported. The ATI RADEON 7500 graphics controllers support only one

installed colormap at one time. Exceeding this limit will cause colormap flashing, also known as

"Technicolor".

Applications should not install or de-install colormaps themselves. The window manager should

perform these actions. However, the application is responsible for providing the window manager with

hints as to which colormaps to install or de-install. You provide this information using the Xlib function

XSetWMColormapWindows(). This function sets the WM_COLORMAP_WINDOWSproperty for a given

window.

Default Visual Information

The ATI RADEON 7500 graphics controller can only support one visual type at one time. Supported

default visual types are 8-bit PseudoColor and 24-bit TrueColor. The default depth and visual class is

24-bit TrueColor. To change the default visual, you must edit the Xserver's configuration file which is

located at /etc/X11/XF86Config.

The depth is set in the Screen section of the Xf86 configuration file. There also needs to be a Display

subsection with the correct depth. For example, the following lines will select a 24-bit default depth

visual:

Restart the Xserver after editing the Xserver configuration file for the new default depth to take affect.

Configuring Graphics Resolution or Vertical Refresh Rate for HP-

Use the sam program to modify the graphics resolution or refresh rate.

Current Graphics Resolution

The default graphics resolution and refresh rate are 1280x1024 at 75Hz. The current graphics

resolution and refresh rate of a running system can be obtained by executing the command

/opt/graphics/common/bin/setmon –p.

How to Change the Resolution and Refresh Rate

1. Log in to the system as root.

2. Run /usr/sbin/sam. Choose Display-> Monitor Configuration. All graphics cards in the system are

listed. Choose the graphics device that is to be updated. From the pull-down menu, choose Actions-

>Modify Monitor Type. A new menu appears that contains all of the possible resolutions and refresh

rates. Choose the new setting and press OK. The selected values will be the new resolution and

refresh rate for the Xserver.

NOTE: See Table 4-1 for supported resolutions and refresh rates.

3. Restart the Xserver.

HP-UX Configuration

ATI RADEON 7500 PCI Graphics Controller Installation Guide

Multihead Support

Multihead support is provided through changes to the Xserver’s configuration file which is located at

/etc/X11/XF86Config. In order to do this correctly, you will need to know which device files to use. See

“Verification of Hardware Installation” on page 17 for details on how to determine which device files to

use.

Dual-screen

By default, an ATI RADEON 7500 appears as a single screen device. You can configure your system so

two screens are created with the signal of the first screen (:0.0) coming out the VGA port and the signal

of the second screen (:0.1) coming out the DVI-I port. Configuring your system for two screens on the

single ATI RADEON 7500 board is referred to as dual-screen mode.

XF86Config Changes

There are three sections in the configuration file you need to change:

1. ServerLayout section. The ServerLayout section contains references to the Screen: sections.

2. Screen sections. The Screen sections in turn contain references to the Device sections.

3. Device sections.

For this example, we will assume there are two ATI RADEON 7500 graphics controllers in the system.

These graphics cards have the device files /dev/gvid0 and /dev/gvid1. We will change the XF86Config

file to allow for a three-screened multihead system. The first graphics card (e.g. /dev/gvid0) is dual-

screened and the second graphics card is single-screened.

The lowest level is the Device section. This maps a physical device to a device identifier. The three

Device sections for this example are as follows:

Section “Device”

Identifier “ATI Radeon 7500 QW(0) Connector 1”

DeviceFile “/dev/gvid0”

EndSection

Section “Device”

Identifier “ATI Radeon 7500 QW(0) Connector 2”

DeviceFile “/dev/gvid0”

Screen

EndSection

Section “Device”

Identifier “ATI Radeon 7500 QW(1) Connector 1”

DeviceFile “/dev/gvid1”

EndSection

The first device, ATI Radeon 7500 QW(0) Connecter 1 is the first screen on the first device. The second

device, ATI Radeon 7500 QW(0) Connecter 2 is the second screen on the first device. Note that it has

the Screen 1 field, which selects the second video output on the graphics card. If this field is omitted, it

is assumed the device is using the first video output on the graphics card. The third device, ATI Radeon

7500 QW(1) Connecter 1 is the first screen on the second device.

Once the Device sections are defined, you can define the Screen section, which maps a screen to a

physical device. The Screen sections use the Identifier field that was defined for each of the Device

sections. The three Screen sections for this example are as follows:

Section Screen

Identifier “Screen 1-1”

Device

Monitor

“ATI Radeon 7500 QW(1) Connector 1”

“Monitor 0”

# Include other Screen info here, including other SubSections

EndSection

The first Screen section maps the screen Screen 0-1 to the physical device ATI Radeon 7500 QW(0)

Connector 1. The second Screen section maps the screen Screen 0-2 to the physical device ATI Radeon

7500 QW(0) Connector 2. The third Screen section maps the screen Screen 1-1 to the physical device

ATI Radeon 7500 QW(1) Connector 1.

Once you have the Screen sections set up, you can set up the ServerLayout section. The ServerLayout

section uses the Identifier field that was defined for each of the Screen sections. The ServerLayout

section describes all of the screens used by the Xserver. The ServerLayout section for this example is as

follows:

Section ServerLayout

Identifier “Main Layout”

Screen

“Screen 0-1” 0 0

“Screen 0-2” RightOf “Screen 0-1”

“Screen 1-1” RightOf “Screen 0-2”

InputDevice “Mouse0” “CorePointer”

InputDevice “Keyboard0” “CoreKeyboard”

EndSection

This ServerLayout has three screens associated with it. These screens are accessed through the 0.0, 0.1

and 0.2 displays. The first screen is associated with the Screen 0-1 Section and is the anchor screen (at

location 0, 0). The second screen is associated with the Screen 0-2 Section and its screen coordinates are

to the right of the first screen. The third screen is associated with the Screen 1-1 Section and its screen

coordinates are to the right of the second screen.

This example shows how to build up a ServerLayout that uses a specific Screen which in turn uses a

specific physical device.

Messages

Xserver messages are typically logged to /var/X11/Xserver/logs. The two files that contain the

messages are:

/var/X11/Xserver/logs/Xf86.*.log

/var/X11/Xserver/logs/Xstartup.*.log

Where *is the display instance of the Xserver, which is usually 0. The Xstartup.*.log file contains

messages from the X loader. The Xf86.*.log file contains messages from the Xf86 Xserver. The

Xf86.*.log file is the file that should be checked first, should problems arise.
