Intel® Embedded Graphics Drivers FAQ

General questions

1.  What are the differences between Intel® Embedded Graphics Drivers and Intel® Embedded Media Graphics Driver?

 

Intel® Embedded Graphics Drivers and the Intel® Embedded Media Graphics Driver (Intel® EMGD) are two separate media and graphics drivers for embedded usage; Intel® EMGD is not a follow-on/next generation driver to Intel® Embedded Graphics Drivers.

 

Intel® Embedded Graphics Drivers is a group of drivers that support a broad range of operating systems and chipsets. Please refer to each driver’s release notes, feature matrix, and product brief for the list of Intel® Embedded Graphics Drivers supported products and operating systems as it is different than Intel® EMGD.

 

The following are supported by the Intel® Embedded Graphics Drivers only: The Intel® Atom™ processor 400 and 500 series (CPU+GPU), Intel® Q45/G45/G41 Express Chipset, Mobile Intel® GM45/GL40/GS45 Express Chipset, Intel® Q35 Express Chipset, Mobile Intel® GLE960 Express Chipset, Mobile Intel® GME965 Express Chipset, Intel® Q965 Express Chipset, Mobile Intel® 945GME Express Chipset, Mobile Intel® 945GSE Express Chipset, Intel® 945G Express Chipset, Mobile Intel® 915GME Express Chipset, Intel® 915GV Express Chipset, and Mobile Intel® 910GMLE Express Chipset.

 

The Intel® EMGD should be used to support new designs based on Intel’s Atom™ processor E6xx series and Intel® System Controller Hub US15W-US15WP- and US15WPT-based designs as Intel® EMGD is a newer driver that supports different processors and platforms than Intel® Embedded Graphics Drivers.

 

The Intel® Atom™ processor E6xx series is only supported by Intel EMGD.

 

2.  What are the benefits of Intel® Embedded Graphics Drivers?

 

The Intel® Embedded Graphics Drivers are developed specifically for embedded Intel® architecture-based platforms, offering a flexible alternative to drivers designed for the desktop, mobile, and MID market segments. Intel® Embedded Graphics Drivers offer Intel's embedded customers extended life support that correlates with the extended life support of embedded silicon products. Intel® Embedded Graphics Drivers differentiates itself through its configuration and support of unique embedded market segment requirements, including an unprecedented support of advanced display combinations and non-standard display dimensions (Intel® Dynamic Display Configuration Technology) and embedded operating systems such as Microsoft XP Embedded* and Windows Embedded CE*, while delivering comparable 3D performance to that of the Intel® Graphics Media Accelerator (Intel® GMA) graphics solution, and performance advantages to open source graphics solutions. Intel® Embedded Graphics Drivers have also been validated on specific Linux distributions and Microsoft Windows* operating systems.

 

3.  We want to use a specific Linux distribution not listed by Intel® Embedded Graphics Drivers documents. Will Intel® Embedded Graphics Drivers work on this Linux? If not, what do I have to do to make it work?

 

The Intel® Embedded Graphics Drivers feature matrix, product brief, and user guide lists which Linux distributions are proactively validated for a given chipset. If your “favorite Linux” distribution is listed in the feature matrix, product brief and/or user guide then the Intel® Embedded Graphics Driver should work. However, in the event the driver does not work perfectly on that distribution, you should work with the “favorite Linux” distribution company or your own in-house Linux experts to determine root causes and debug any issues.

 

If your “favorite Linux” distribution is not listed in the feature matrix, product brief and/or user guide then the chance of the driver working is lower. You can consider trying to install Intel® Embedded Graphics Drivers on a system with the help of your “favorite Linux” Linux distributor. However, a technical solution may not be possible.

 

To better understand how the Intel® Embedded Graphics Driver for Linux works (and how different kernel versions will affect the driver), you need to know how the Intel® Embedded Graphics Driver Kernel Module (IKM) module is built. Currently, the install.sh script detects a limited set of known or validated Linux distributions and makes a copy of the relevant kernel headers for AGPGART and DRM. Stay tuned for a future white paper discussing the drivers’ Linux integration methods.

 

4.  Will Intel® Embedded Graphics Drivers work with all embedded Intel chipsets and SoCs?

 

No, only the following chipsets and/or system-on-a-chips (SoC) are supported with Intel® Embedded Graphics Drivers:

 

  • Intel® Atom™ processor D400/500, N400/500 series
  • Intel® Atom™ Z500 series with Intel® System Controller Hub US15W/WP/WPT
  • Intel® Atom™ N270 with Mobile Intel® 945GSE Express Chipset

  • Intel® 915GV Express Chipset

 

5.  I need support for a chipset or operating system not listed as being supported by the current driver. What can I do?

 

If the chipset or operating system is an older one, there may be an older Intel® Embedded Graphics Drivers version that supports it. If the chipset is in the same family as one currently listed in the Intel® Embedded Graphics Drivers user guide as being supported, please contact an Intel representative to discuss your requirements for a different operating system to be supported.

 

6.  How long will the Intel® Embedded Graphics Drivers be supported?

 

Intel® Embedded Graphics Drivers offer Intel's embedded customers multi-year extended life support that correlates with the extended life support of on-roadmap Embedded and Communications Group silicon products. This roadmap is available by contacting your Intel representative. Technical, production status, and other relevant information on Intel's embedded products can be found on Intel's Embedded Design Center or on Intel’s product information page (ark.intel.com).

 

7.  Where can I get detailed roadmap information (dates, features, and so on)?

 

Roadmaps and future releases are forward-looking plans subject to adjustments for new technologies and customer/market requests. Contact your Intel representative for the Intel® Embedded Graphics Drivers and Intel® EMGD master plan-of-record (POR) update.

 

8.  How can the Intel Embedded Graphics Drivers help with customized display timings for flat panel displays?

 

The Intel Embedded Graphics Drivers were designed to enable the customer to configure the driver to support the platform. The Intel Embedded Graphics Drivers can support many flat panel configurations with custom timings through the Detailed Timing Descriptor (DTD) page of the Configuration EDitor (CED) without driver changes.

 

9.  Will the Intel Embedded Graphics Drivers work for extended display identification data (EDID)-less panels?

 

The Intel Embedded Graphics Drivers achieve EDID-like support for EDID-less panels via configuration (using CED), custom-created Detailed Timing Descriptor (DTD) timings, and configuration files. More information on how to generate correct Intel Embedded Graphics Drivers for LVDS panels is available in the user guide.

 

10.  Will the Intel Embedded Graphics Drivers support multiple generations of chipsets and SoCs? Will I have to change my driver for a new chipset or SoC?

 

The Intel Embedded Graphics Drivers support multiple generations of Intel chipsets and/or system-on-a-chips (SoC) over the extended support span of Embedded Intel® architecture-based platforms, from the Mobile Intel® 910GMLE Express Chipset forward to the Intel® System Controller Hub US15W chipset, based on the Embedded Intel® architecture roadmap. However, you must build a driver for each specific chipset or SoC you are using, and you may need to update to a later version of Intel Embedded Graphics Drivers to be able to build a driver for a newer chipset. The earliest chipset with integrated graphics that is supported by the Intel Embedded Graphics Drivers is the Intel® 815 chipset. The last release that supports the Intel® 815 chipset was the Intel Embedded Graphics Drivers release 5.1, which remains available through your Intel representative. The last release that supports the Intel® 845 chipset was the Intel Embedded Graphics Drivers release 6.1, which remains available through your Intel representative. The last release that supports the Intel® 852/855 chipset was the Intel Embedded Graphics Drivers release 8.1, which remains available through your Intel representative.

 

The following Intel® GenX/Gen3/Gen4 chipsets are supported only by Intel Embedded Graphics Drivers 10.3.1 which were the last validated drivers for these chipsets available on EDC.

 

  • Intel® Q45, G41, and G45 Express Chipsets

  • Intel® Atom™ processor Z500 series with Intel® System Controller Hub US15W/US15WP/US15WPT
  • Intel® Atom™ processor N270 with Mobile Intel® 945GSE Express Chipset

 

11.  Can I use the Intel Embedded Graphics Drivers in conjunction with a standard desktop video BIOS?

 

Yes, this is possible. The Intel Embedded Graphics Drivers provide the capability using the Configuration EDitor to configure both the OS level driver and the video BIOS with the same settings. Although the Intel Embedded Graphics Drivers will utilize settings of the embedded video BIOS, the OS-level drivers are not dependent on the video BIOS settings. This allows users who may not have the ability to update their system firmware/system BIOS to install and use the Intel Embedded Graphics Drivers with their operating system. Note that the Configuration EDitor will not create settings for the standard desktop video BIOS.

 

If you require specific capability in the standard desktop video BIOS in conjunction with the Intel Embedded Graphics Drivers, use Intel's BIOS Modification Program (BMP) tool to configure the standard desktop video BIOS and CED (Configuration EDitor) to configure the Intel Embedded Graphics Driver. Contact your Intel representative for more details.

 

12.  Can I use the new Intel Embedded Graphics Drivers in conjunction with an older Intel Embedded Graphics Driver video BIOS?

 

Although not always required, it is generally recommended to upgrade both the VBIOS and driver when an update occurs. Intel tests using only the latest of both VBIOS and driver so there may be unexpected results. Often there are code changes that you will want. Sometimes there are new features that require both to be updated. If after updating only the driver you see a negative change in operation, it is recommended that you then update the platform to the newer VBIOS as well. This will allow you to verify that the negative operation of the driver was or was not related to some interaction with the older VBIOS.

 

13.  Can I use the Intel® Graphics Media Accelerator Drivers (Intel® GMA Drivers) with the Intel Embedded VBIOS?

 

No. Intel Embedded Graphics Drivers operates with the Intel Embedded Graphics Drivers VBIOS, but the standard GMA desktop drivers are dependent on the settings in the GMA Video BIOS and must use the associated GMA Video BIOS. The Intel Embedded VBIOS will work only with the Intel Embedded Graphics Drivers.

 

14.  Does Intel provide any codecs for video decoding with the Intel Embedded Graphics Drivers package?

 

Yes, Intel provides Linux and Windows CE* codecs for evaluation purposes only with Intel Embedded Graphics Drivers.

 

15.  The Linux Ubuntu Netbook Remix* (UNR), the “remix” of the standard Ubuntu Desktop release enables it to work better on netbooks or devices with small screens and is optimized for use with the Intel® Atom™ processor. Do Intel Embedded Graphics Drivers support Linux Ubuntu Netbook Remix*? If not, when is support of Linux UNR* planned?

 

No. There is no plan currently for Intel Embedded Graphics Drivers to support Linux UNR*.

 

16.  What features and panels are supported by Intel Embedded Graphics Drivers? Can you differentiate between VBIOS and driver capabilities?

 

Detailed information on supported graphics features, display outputs, and panels is available in the user guide. For an overview, please refer to the Intel Embedded Graphics Drivers Technical Product Specification for Software (TPS). The product specifications include a complete listing of supported features, and can be found on the Intel Embedded Graphics Drivers website. Additional detailed information is available from your Intel representative.

 

17.  Can the drivers be configured during runtime of the operating system?

 

The Intel Embedded Graphics Drivers have run-time APIs that allow for configuration changes in both Windows and Linux versions of the driver. Intel can also provide on request an Intel Embedded Graphics Drivers API Reference Manual or sample code that utilizes these APIs. Contact your Intel representative to request details.

 

18.  Why are the Intel® Embedded Graphics Driver GUI fonts larger than normal and some of the text is off screen when running with Windows XP Embedded*?

 

The Intel® Embedded Graphics Driver GUI requires a particular font, Sans Serif(8) (sanserife.fon). The San Serif fonts need to be copied to the font folder in the Control Panel. These fonts can be copied from a Windows XP* system or obtained from Microsoft. The required fonts are:

 

  • serife_fon
  • seriff_fon
  • sserife_fon
  • sseriff_fon

 

Please make sure that the fonts listed above are in the fonts folder of the Control Panel on the Windows XP Embedded* system.

 

19.  What Intel® Atom™ processor-based embedded platforms are supported with Intel Embedded Graphics Drivers?
