Just about a month ago Intel had released the xf86-video-intel 2.4.0 driver for their IGP graphics graphics hardware running X.Org. This update brought Intel GMA X4500HD support, Intel 965 EXA RENDER extension improvements, HDMI support, and much more. Today though Intel has issued its first bug-fix release for this open-source driver.
For those into reading some hardware specifications, Intel has released the Extensible Host Controller Interface draft specification for USB 3.0. The revised xHCI 0.95 USB 3.0 specification is expected later this year. USB 3.0 "Super Speed USB" was first mentioned last year during the Intel Developer Forum in September (USB 3.0 Details). USB 3.0 will be backwards compatible with existing USB 1.1/2.0 devices and offer ten times the performance of USB 2.0, along with a host of other features. The royalty-free USB 3.0 specification can be read on Intel's website along with their press release.
There was the Core and Core 2 series of Intel desktop processors with Solo, Duo, Quad, and Extreme postfixes, while today Intel has announced their Core series will continue with their upcoming Nehalem processors. The processors based around their forthcoming Nehalem micro-architecture will be branded as the Intel Core i7.
The xf86-video-intel 2.4 driver was just released about three weeks ago, but we're already well into the xf86-video-intel 2.5 development cycle, which will be Intel's next quarterly graphics driver release. Intel's Jesse Barnes has provided a brief status on the code mergers taking place for this next open-source release.
Following concerns regarding the TTM memory manager, Intel had introduced their own kernel memory manager for graphics processors which they have called GEM, or the Graphics Execution Manager (A Technical Explanation of GEM). Intel's GEM is designed to be easier to implement than Tungsten's TTM that had only lived in the limelight for a short time.
XAA, or the XFree86 Acceleration Architecture, is over twelve years old and finally in 2005 it was greeted by a replacement, EXA. XAA is nearing an end-of-life and Intel is prepared to remove XAA acceleration within their next Intel graphics driver release later this year. EXA was designed to offer speed improvements over XAA by accelerating more options and enhancing X's RENDER extension. Depending upon the driver, it wasn't until recently though that EXA really did have some modest speed advantages. A new acceleration architecture has now joined the mix. Intel's Keith Packard has announced UXA, which is short for the UMA Acceleration Architecture.
Intel's Larrabee will not launch for another year or two, but additional details were shared this week on this project that will launch Intel into the discrete graphics arena. We've known this already, but Larrabee will be a many-core graphics processor with an x86 instruction set designed to compete with the graphics cards from both ATI/AMD and NVIDIA.
The xf86-video-intel 2.4.0 driver was released last week with support for GMA 4-Series Support, EXA Render improvements, and other enhancements. Now planning is already underway for the next driver release, version 2.5.0. Jesse Barnes is serving as the release manager for xf86-video-intel 2.5 and so far he has planned the following changes:
At OSCON 2008, Linux on mobile devices has been an extremely hot topic. This morning Intel's Dirk Hohndel had keynoted about their Atom-based mobile devices and netbooks and this afternoon he had a smaller session where he talked in greater detail about Moblin and what will be known as Moblin 2.0.
It's been about three months since the xf86-video-intel 2.3.0 driver was released and today they have now issued their next quarterly update. Version 2.4.0 of this Intel X.Org graphics driver brings GMA 4-Series support (including their new flagship X4500 IGP), improved i965 EXA Render performance, integrated HDMI support, and SDVO-HDMI support. In addition, there are many more minor fixes and changes, which are detailed in the xf86-video-intel 2.4.0 release announcement. At Phoronix we shared last month that this new driver update would be available in July.
This week Intel has unveiled its Centrino 2 platform that had been codenamed Montevina. The Centrino 2 notebook platform supports 45nm Penryn processors, GMA 4-Series graphics, up to DDR3-1333MHz support, DisplayPort/HDMI/DVI/VGA connectivity, 802.11g/n WiFi with an add-on card for 802.16 WiMax, and many other Intel innovations. Montevina will be the competition to AMD's Puma Platform that was introduced last month at Computex Taipei.
Back in May while open-source X developers were bickering about their TTM memory manager concerns, Intel's Keith Packard chimed in and announced Intel's Graphics Execution Manager, or GEM for short. The Graphics Execution Manager is Intel's replacement of Tungsten's TTM for their xf86-video-intel graphics driver. GEM seems to make memory management simpler and address some of the TTM shortcomings.
If you use the xf86-video-intel driver in a media box or just commonly watch movies using XvMC (X-Video Motion Compensation) for video acceleration of MPEG-2 files, you may want to check out the latest work going on to the Intel driver. No, XvMC doesn't yet support more video formats like Intel's Keith Packard had talked about at FOSDEM. Committed last night were nine XvMC-related patches to the xf86-video-intel git master branch for this open-source graphics driver. There's nothing groundbreaking about these updates, but a number of fixes and the batch buffer size has been increased.
Earlier this week support for Intel's GMA 4-Series Chipsets was committed to the xf86-video-intel DDX driver and OpenGL support in Mesa. In preparation for the forthcoming Intel GMA X4500, the Intel Linux driver has received some added work last night. In particular, HDMI should now be working with Intel hardware. In addition, DisplayPort registers have been added to the Intel driver, but it doesn't look like that connection is fully supported yet. These features should be part of the xf86-video-intel 2.4.0 driver release.
Committed this afternoon to the xf86-video-intel driver development branch at FreeDesktop.org is support for Intel's GMA 4-Series Chipsets. The 4-Series IGPs (namely the Intel X4500) are brand new and is designed to be three times faster than the current Intel GMA X3100. The commit for the G45 Linux graphics support can be viewed here. More information on the Intel G45 chipset can be read at Intel's website. Kudos to the Intel developers for delivering prompt support.
Intel's Eric Anholt has announced on the dri-devel mailing list that they are getting close to merging GEM to master. There was one last bug hitting the GEM folks but that seems to be worked out and the Intel engineers will proceed to merge GEM to master in all three repositories.
PowerTOP is an incredibly handy open-source utility of Intel's that had first premiered a year ago. As of this week, however, PowerTOP has been ported over to OpenSolaris. PowerTOP 1.0 was released for OpenSolaris, which is more or less an equivalent to the Linux version (which is currently at v1.9). This power conservation utility is for both x86 and SPARC architectures. This OpenSolaris port does, however, have some outstanding bugs and currently it doesn't have the power-savings recommendation feature. If you're interested, check out its project page.
Having been in development for a few months now and going through a couple development releases, version 2.3.0 of the xf86-video-intel driver has been released. The 2.3 release represents Intel's Q2'08 open-source driver update and the biggest change is the addition of XvMC (X-Video Motion Compensation) support for the Intel 915/945 IGPs. This graphics driver also has improved stability and a horde of bug-fixes. The release announcement and source download links can be found on the xorg-list. xf86-video-intel 2.3.0 will be part of the forthcoming X.Org 7.4 release.
Intel's Zhenyu Wang has announced the release of xf86-video-intel 22.214.171.1243, which is another Intel X.Org driver test release prior to version 2.3.0. xf86-video-intel 2.3 will officially introduce XvMC support, code cleaning, bug-fixes, improved quirk handling, and other changes.
In Linux graphics news unrelated to the recent ATI/AMD excitements, Intel has just released the xf86-video-intel 126.96.36.1991 driver. This driver is meant to serve as the first release candidate for what will become xf86-video-intel 2.3.0. The biggest change since the 2.2 release is that the XvMC support has been merged to master! Intel's open-source XvMC implementation currently works with the Intel 915, 945 and G33 IGPs, but the 965 XvMC support is currently problematic. Intel's XvMC support was previously found in a separate development branch. Aside from these video playback improvements, the Intel 2.3 RC1 driver has many bug-fixes, a few added quirks, code cleanups, and other improvements.
Intel's Eric Anholt has been working on pulling Render improvements for the Intel 965 IGP chipset out of the intel-batchbuffer branch of the xf86-video-intel driver and pushing them into the mainline driver. These mainline Render improvements aren't yet there, but Eric has the code right now in his personal Intel git repository on FreeDesktop.org. Stopping this work right now are color correctness issues.
The xf86-video-intel 2.2.1 driver update has been in the cooker now since this past December, and today on the eve of FOSDEM it has finally been released. The Intel 2.2.1 X.Org video driver is a maintenance release that addresses a large number of bugs since the release of the 2.2.0 driver. Not all blocker bugs were addressed for this release, but an Intel 2.2.2 driver update is possible (permitting enough interest). The next major xf86-video-intel driver update will come in the way of version 2.3. This next update is expected to reduce mode-setting flickers and deliver on other improvements. The xf86-video-intel 2.2.1 driver release announcement can be read on the X.Org mailing list.
We've known since last month that Intel's X.Org display driver would be having a v2.2.1 release soon, and it now looks like it will be released this week. No new features will be introduced until the Intel 2.3.0 driver, but the 2.2.1 release will address a variety of outstanding bugs. Jin Gordon is calling for those in Intel's new driver testing program to test out the latest code in the xf86-video-intel-2.2-branch while using the latest DRM, Mesa, and Xserver components. Presently there are three bugs attached to the Intel 2.2.1 blocker bug.
Last May Intel had introduced PowerTOP as an open-source utility for monitoring a system's power consumption and making recommendations on how to reduce the power consumption thereby extending the battery life for mobile devices. Today, however, Intel has announced a new sibling for PowerTOP: LatencyTOP. Intel's LatencyTOP is a tool geared for developers that are interested in visualizing system latencies. LatencyTOP is able to detect where system latencies are originating and displaying the maximum and average time needed for each task. We'll be exploring this new open-source utility further and will report our results on LatencyTOP in the near future. More information is available from LatencyTOP.org.
Intel's Gordon Jin has announced today that the Intel graphics driver team is looking to establish a closer relationship with the Intel X.Org community of both end-users and engineers. To do this, Intel has created a new community testing program. This Intel testing program is designed to help in the testing of platforms not officially supported by the Intel validation team and bugs that are only experienced in very specific hardware/software configurations.
Intel's Zhenyu Wang has announced the creation of the "xvmc" branch in the xf86-video-intel driver. This new branch features code clean-ups relating to X-Video Motion Compensation (XvMC) and a new framework that will support greater hardware media decoding functionality in the future. The xvmc branch is designed to replace the earlier "xvmc-i915" branch. In addition, libIntelXvMC.so replaces libI915XvMC.so. Along with this new branch and framework, an XvMC option has been added to Intel's driver for the xorg.conf to disable this feature, which comes enabled by default.
The Intel X.Org 2.2.0 Driver was released just about a month ago, but a bug-fix v2.2.1 release is planned for the near future. Jesse Barnes mentioned on the FreeDesktop.org mailing list that the 2.2.1 release will address some of the recent regressions in this open-source Intel video driver. There is a 2.2.1 blocker bug, which currently has five open bugs (another five are already closed), but the two major regressions that this release will cure is X-Video crashing and a pipe enable bug. The Intel EXA performance issues will not be fixed until a later release.
We knew that a new Intel driver was coming and now the xf86-video-intel 2.2.0 driver has finally arrived. This new Intel driver for X.Org closes over 160 bugs (with 96 bugs left to squash), but xf86-video-intel 2.3 should address even more bugs. This new Intel display driver requires X server 1.4, Mesa 7.0, and the DRM module. The release announcement can be read on the X.Org mailing list.
It's been six months since Intel had introduced their xf86-video-intel 2.0 driver for graphics adapters on X.Org and two months since their most recent release (v2.1.1), but we are on the heels of a new Intel driver release. The Intel X.Org video driver will soon reach version 2.2.0 and contains a number of fixes and other enhancements since the xf86-video-intel 2.1 release. Among the many changes include defaulting to EXA as opposed to XAA, 965 IGP fixes, and improved support for G33/35 integrated graphics. Most of the changes, however, are just fixes. Just about 15 minutes ago, Jesse Barnes of Intel had bumped the driver version to 2.1.99, which will be the testing pre-release prior to the xf86-video-intel 2.2 introduction. Jesse had confirmed this information on the X.Org mailing list. Of course, once the Intel 2.2 X.Org driver is introduced, we'll be sure to let you know (you can also be notified by subscribing to our RSS feed).
Mobility talks definitely dominated Intel's Developer Forum last month with information from Montevina and Moorestown to the next-generation Mobile Internet Devices from various vendors. However, talks on multi-core computing definitely ranked high (along with PCI Express 2.0, PCI Express 3.0, and USB 3.0). With technologies like Intel Threading Building Blocks 2.0, Pervasive DataRush, it's time to prepare for a world of massively multi-core computing. Multi-core computing is here and it's here to stay. From assisting in real-time 3D surgery simulations to on-the-fly computerized language translations, many cores will be required.
