RadeonHD DRM Begins To Show

The RadeonHD DRM isn't yet in a usable state to end-users, but Matthias Hopf has pushed his latest RadeonHD work into his personal git tree. DRM is now able to initialize on an RS690 GPU, but DRI isn't working yet. Nor does Matthias's code work with 2D acceleration currently. However, he does hope to have this code working within a few weeks. The git URL and his message can be read on the RadeonHD mailing list. Luc Verhaegen has also made a very interesting RadeonHD enhancement without DRM, which could be available for public showing soon.

RadeonHD 1.2.1 Driver Released

Just four days ago the RadeonHD 1.2.0 driver was released as the first xf86-video-radeonhd driver update in several months. The RadeonHD 1.2.0 driver added support for several new Radeon HD 3XXX GPUs, R500 2D XAA/EXA acceleration, and many other underlying changes. Today, however, that release has been succeeded by RadeonHD 1.2.1.

Open-Source Radeon Driver Improvements

The RadeonHD crew yesterday released xf86-video-radeonhd 1.2.0 while the xf86-video-ati developers (mainly Alex Deucher) have been working on a few commits for their competing driver. There have been about a dozen commits to this driver tree in the past 24 hours. The changes mostly come down to EXA/TexturedVideo improvements as well as some code cleaning. If you use this driver, be sure to check out the latest development code.

RadeonHD Driver Improvements

Committed to the xf86-video-radeonhd git tree today have been 17 changes to this open-source ATI R500/600 graphics driver. AMong the changes are adding full support for the RS690 IGP family, support for interlaced modes, and better support for LVTMA TMDS macro control values. All of the changes with today's drivers can be found in their public git tree at FreeDesktop.org. IRC logs from the RadeonHD channel are available at RadeonHD.org.

Dynamic Clocks For Radeon R500+

When it comes to ATI open-source power management, so far AMD's open-source kindness has just yielded a list of registers but no proper documentation or how PowerPlay exactly works. However, AMD's Alex Deucher has just committed "Dynamic Clocks" support for the Radeon R500 and R600 graphics cards. Dynamic Clocks just provides dynamic clock gating and static power management, permitting the graphics card supports this capability. With some graphics cards it's already been setup through the video BIOS, so today's work isn't relevant to everyone. Dynamic Clocks is not nearly as elaborate as PowerPlay, but it's a good start for the xf86-video-ati driver.

AMD Releases Revised R500 Document

In late February AMD had released the much anticipated R500 3D programming guide followed my two minor revisions to it over the past month. Today AMD has released another revision to the R500 3D programming guide, which now includes expanded coverage of the Command Processor (CP) found on the R500 graphics processors. Version 1.3 of this documentation can be downloaded from X.Org.

AMD's "Mystery" Digital Block Supported

For those using motherboards with the AMD RS690 IGP, the DDIA Digital Block is now supported by the RadeonHD (xf86-video-radeonhd) driver. DDIA is the second digital block on this IGP that came as a mystery to both AMD and the RadeonHD developers as they believed no motherboard vendors were actually using this block. With this latest code addition, two displays should now work with the RS690 in an independent fashion. Check out the latest xf86-video-radeonhd git code if you're one of these RS690 owners. A few other code fixes were also committed this afternoon.

ATI "r500-fp" DRM Merged To Master

Last Thursday, David Airlie achieved hardware-accelerated glxgears on an open-source R500 Mesa implementation based upon the earlier R300 code. This is a big step forward for open-source 3D on these newer ATI Radeon graphics cards, but it's still a work in progress. However, this morning David Airlie has merged his Mesa/DRM work to the mainline DRM branch. This work, previously housed in his personal git tree under the branch "r500-fp", can now be found in the master Mesa/DRM git. His Mesa work (in the "r500test" branch) still hasn't been merged to master as there is more work to be done on that side.

Full EXA Composite For R300-500 GPUs

Alex Deucher has been working on delivering full EXA Composite support for the Radeon driver and today the first bits of this work are available via his personal git repository. The full EXA Composite not only covers the R300 and R400 generations, but it already supports the Radeon X1000 (R500) graphics cards! In Alex's blog post he mentions that some blend combinations still need to be debugged, but the R300/400 support in general is pretty solid. For the R500 support, full EXA compositing is working for some graphics cards but not others. For those interested in trying out this latest Radeon work, check out the r3xx-render branch (well, until it gets merged to master). On the other side of the table, currently the RadeonHD driver lacks full EXA Composite support.

ATI R200 Documentation Coming Too

In the Phoronix Forums following Friday's release of the (NDA-free) ATI R300 3D register information, AMD's John Bridgman has confirmed that he is looking to release documentation going back to the ATI Radeon 8500 era graphics processors. Years ago ATI had released this R200 documentation to the open-source driver developers at the time, but it was encumbered by legal restrictions.

AMD Hybrid Graphics For Linux?

At CeBIT 2008 in Germany, AMD today announced the 780 Series Chipset. This budget-minded motherboard chipset, which is compatible with Quad-Core Phenom CPUs but a step-down from the 790FX Chipset, takes on gaming and high-definition computing for mainstream PC users on both the desktop and mobile platforms. What is special though about this chipset is its support for AMD's Hybrid Graphics Technology.

AMD Updates Its 3D Programming Guide

Less than a week after AMD introduced its R300-500 3D programming guide, they have today pushed out a revised 3D programming guide. This updated documentation covers more vertex program formats than the v1.1 draft that had come out just before FOSDEM 2008. This addition adds four pages onto the 3D documentation, making it now 266 pages long. This documentation can be downloaded from the AMD developer website.

A Flurry Of OSS ATI Driver Improvements

Since AMD openly released the R300-R500 3D programming documents this past Friday, it has led to a flurry of improvements with the xf86-video-ati "Radeon" driver. On the same day as the document release, Textured Video for the R100-400 series was committed to master followed by Textured Video for the R500 series the next morning (and Rotate support as well). Succeeding that work over the past few days has been many commits to the xf86-video-ati tree. These 30+ commits mostly contain fixes and filling in previously unknown areas. The Mach64 and r128 drivers, which previously could be found in xf86-video-ati have been split out and are now housed in xf86-video-mach64 and xf86-video-r128, respectively. Clipping for Textured Video in the Radeon driver has also been corrected. If you extensively use the open-source Radeon driver for the R100-500 series, you may want to check out the latest xf86-video-ati driver from git.

OSS R500 Driver Gets Textured Video Too

When John Bridgman mentioned at his FOSDEM talk that Textured Video support may be arriving soon, we didn't realize that it would end up being just hours away! Shortly after Alex Deucher had committed R100-400 Textured Video support, David Airlie went ahead and implemented Textured Video support for the R500 series. Furthermore, Rotate support has also been added by David for the R500 series. Note, however, that there may be a bug in the clipping with the current Rotate support. The R500 Textured Video support already is great news to see coming just a day after the AMD 3D document release.

Radeon Driver Gets Textured Video (Xv)

We reported earlier today from FOSDEM that Alex Deucher had been successful in getting Textured Video (X-Video) with the Radeon driver on R300 class hardware and that the R500/600 series could even support it in the near future. Well, support for Textured Video on the R100 to R400 has today landed into the xf86-video-ati git tree. This TexturedVideo support, which can be used by any video player that supports using X-Video, was derived from Eric Anholt's KDrive ATI video code. If you're an R100-400 owner interested in improved open-source video playback, be sure to check out the latest code and report your results. This commit today doesn't introduce the support for the R500/600 series quite yet.

What Will AMD Open Up Next?

With the Friday night release of the R300-500 3D programming documentation, which open-source developers have already been pleased by, what will be AMD's next strategic OSS move? AMD is still in the process of releasing an R600 3D programming guide, Tcore, the bottom layer of the fglrx driver (possibly), and other information. These efforts are all to better enable the open-source community in developing the R500+ RadeonHD driver and further enriching the R300/400 Radeon driver. They have also stated their intentions on releasing sensor information so that ATI graphics cards with supported temperature probes and fan controllers can be supported by LM_Sensors.

AMD Opens Up Their Performance Library

In another move of good faith for the open-source community, AMD has today announced it has opened up their once proprietary AMD Performance Library. The AMD Performance Library, or APL for short, has been opened up under the name of Framewave. AMD's press release drumming up this announcement describes its goal as " to further enable the performance-optimized APL and expand its functionality beyond the existing core media capabilities, ensuring developers have an accelerated conduit to high performance application development." The AMD Performance Library / Framewave covers a multitude of operations from simple math operations to media processing and optimizations for multi-core environments. Among the supported operations are H.264 video decoding. The Framewave project is housed over at SourceForge and at the AMD Developer Center.

ATI R700 Series Gain ALSA HDMI Audio

While the Radeon R700 series of graphics processors aren't yet available, it's getting closer to release, and yesterday the ALSA development tree picked up support for HDMI audio on the R700 series. This patch, which was submitted by one of AMD's engineers, adds support for the RV710, RV730, RV740, and RV770 GPUs. This support can be found in the hda-intel driver in the Advanced Linux Sound Architecture (ALSA). The Radeon R600 series was first to introduce an embedded audio processor for use when using the HDMI adapter (Using HDMI With ATI Linux Drivers). Support for the R600 series has already been in ALSA.

AMD Launches Open GPU Website

AMD has today launched their new open GPU documentation website for register-level documents covering their ATI Radeon products. In addition, they are now providing an email address for any open-source developers who may have questions concerning these documents. No new documents are being published today, but this page is just offering up the previously-released M56, M76, RV630, and RS690 documentation from their previous two drops. The 3D (and R600 2D) "tcore" documentation should be released soon though (FOSDEM? :)).
