It's time for another issue of the Nouveau Companion, which talks about the development work done on the open-source 2D/3D NVIDIA driver over the past two weeks. Among the topics talked about in this issue include PlayStation 3 graphics via Nouveau, using TTM memory manager, and the Gallium3D architecture. A stable 2D Nouveau driver is about completed with EXA support but currently lacks an EXA implementation on the older NVIDIA hardware and there are still problems with NVIDIA's GeForce 8 hardware.
It's going on two weeks since the RadeonHD driver was made available, which is AMD's sanctioned open-source driver for the Radeon X1000 (R500) and Radeon HD 2000 (R600) series (as well as future generations of AMD GPUs). In this time, we have seen some great progress made with this open-source driver and have a few additional remarks to share about its status and the first bits of this driver's roadmap.
It's been about a month since the last Nouveau Companion, the development newsletter talking about the work going into the open-source 3D NVIDIA display driver, but today the latest edition is now available. Covered in the 27th edition of the Nouveau Companion are details on the progress made in the past month such as with porting the driver to using libpciaccess, bug squashing, 2D acceleration working for NVIDIA's GeForce 8800GTX, X-Video fixes, and RandR 1.2 support was merged back into the Nouveau master branch. The Nouveau developers have received a few new graphics card donations but are still in need of development help and testing.
This past week was marked by the release of the NVIDIA 100.14.19 display driver for Linux and Solaris, which was the first alternative OS driver release from this Santa Clara company in about three months. The public change-log is quite lengthy and finally delivered on fixing the GeForce 8 performance regression. In our GeForce 8800GTS Linux tests, the performance fix was very evident. However, now that we have had the time to run more extensive tests with the GeForce 8 series and this new driver, we have found not everything to be smooth sailing.
After a very slow summer, NVIDIA has finally rolled out an updated Linux proprietary display driver. The release highlights are quite extensive. However, as NVIDIA did not have the courtesy to allow for testing this driver in advance and right now we are out covering Intel's IDF, we do not have benchmarks to share. However, as time permits over the next day or two we hope to publish some new Linux NVIDIA GeForce 8800 benchmarks.
While today's unveiling of the RadeonHD driver for the ATI R500 and R600 series is great news, this driver right now is targeted solely for developers as it's still experimental and doesn't yet support 3D acceleration and other key functionality generally needed in production environments. However, if you are looking to try out this new RadeonHD driver on Ubuntu because you're running into problems with the proprietary fglrx driver or just wishing to report your results, we've documented the installation procedures for Ubuntu.
Not only is AMD providing the open-source community with their ATI GPU specifications, but they have also been partnering with Novell on the development of a new open-source display driver. We've been telling you about AMD's open-source work all month, and today the new driver is finally available for download. It is still very much a work in progress and isn't much further along than the open-source R500 Avivo driver. However, this new driver does support the Radeon HD 2000 (R600) family. This new X.Org driver is called RadeonHD and in this article we have some initial information to share with additional articles coming later in the day.
AMD started delivering on their word of providing GPU specifications to the open-source community without a Non-Disclosure Agreement, and now with the 2007 X Developer Summit having come to a close, we asked several key members of the X.Org community on how they judge AMD's recent move. They were also asked if they believe NVIDIA will follow suit in helping the open-source community. Those that responded were David Airlie, Daniel Stone, Jerome Glisse, Stephane Marchesin, and Oliver McFadden. Mark Shuttleworth had also previously commented on AMD's efforts.
After talking for the past week about AMD's new Linux efforts with announcing a new fglrx Linux driver overhaul and releasing ATI GPU specifications without a Non-Disclosure Agreement, the 8.41 fglrx driver is now released. You can now download this new Linux driver right now.This is the closed-source proprietary driver, however, much of the "engine" for this driver is rewritten and as we have been sharing in articles from the Radeon X800XL performance to the flagship Radeon HD 2900XT there are certainly some new accomplishments coming out of the AMD Linux camp. The new baseline open-source driver written by Novell should also be released shortly. In this article we have a few additional remarks on the AMD 8.41 Linux display driver for ATI Radeon graphics cards.
This past week AMD raised the Linux graphics bar by not only announcing their new fglrx graphics driver, which delivers Radeon HD 2000 support, immense performance improvements, and AIGLX, but it was accompanied by an announcement that they will be delivering specifications to the X.Org development community. These two announcements came after intense work internally at AMD and over a long period of time, but literally overnight it changed the minds of many Linux users on how they judge this company with its once notorious binary blob. AMD has really set a precedence for showing that a semiconductor company once criticized to no end with their proprietary software can update their views to assist and embrace the open-source Linux community while remaining competitive as a company in a triopoloy market. They have also thus reaffirmed that Linux is a viable desktop operating system. But the ball has now landed in NVIDIA's court. NVIDIA can either play ball by pushing forward with a similar effort, and then all of the big three GPU manufacturers would be cradling an open-source strategy, or they may find themselves in trouble down the road.
Mark Shuttleworth, the self-made millionaire and leader of the Ubuntu project, has been very vocal about the adoption of free software and that "the free software approach is a better device driver development model." But what does Mark think about AMD's announcements this week with the 8.41 display driver and the just-announced program where AMD will be handing out specifications under NDA and helping out the open-source community? Mark Shuttleworth has provided Phoronix some of his initial thoughts on ATI/AMD's new Linux push.
Rumors and speculations have been flying around for months about ATI/AMD opening up the source-code to their Linux display driver or providing their GPU specifications to community developers. This for the most part had started after Henri Richard's statement at the Red Hat Summit earlier this year. Well, those rumors can finally be put to rest. AMD will be providing NDA specifications, an open-source library, and there is a new open-source graphics driver as a result. AMD will continue producing a closed-source proprietary driver; however, they are opening the source-code to a critical library with accompanying GPU specifications for X.Org developers. To get the ball rolling, AMD is also funding the development of a new open-source R500/600 driver.
So far today at Phoronix we've published the AMD 8.41 Display Driver Preview, ATI R300/400 Linux Performance, ATI R500 Linux Performance, and ATI Radeon HD 2900XT Linux Performance -- yet, it's only ten minutes past midnight! However, looking at AMD's official statement on the Linux driver, there is a rather interesting sentence about good things to come...
Since Linux support for the Radeon X1000 "R500" series was introduced some 17 months ago, there has been a performance imbalance. The past fglrx drivers have worked, but they've had a difficult time competing with the competition presented by NVIDIA and their Linux driver when it comes to the frame-rate performance. Though as we have been sharing in all of our articles today, the new ATI/AMD Linux driver will be made available in the coming days and it offers some striking performance improvements. In our Mobility Radeon X300 testing, the new driver allowed Doom 3 and Quake 4 to run at playable frame-rates, which simply wasn't possible with the previous 8.40.4 fglrx driver a month ago! The Radeon X800XL performance was also improved significantly, which allowed it to outperform the NVIDIA competition. Now onto the Radeon X1000 family, as you can probably suspect, there are massive performance improvements to be found with these graphics cards as well. In this article we have tested the Radeon X1300PRO, X1800XL, X1800XT, and X1950PRO with the new ATI Linux driver and have found significant performance improvements.
To some extent, ATI's R300 and R400 series is more popular than the R500 (and now R600) series for Linux users. The R300/400 series has a reliable open-source driver and while the performance of the X.Org Radeon driver lags behind ATI's binary driver, it's currently the fastest for offering open-source 3D performance on dedicated graphics cards. With the cards being around much longer, they are also much cheaper and have become somewhat popular for Linux desktops that can power Compiz and Beryl "eye candy" effects. However, it's just not the R500 and R600 series that receive a nice performance boost from the new ATI/AMD Linux driver, but so does the R300/400 series. Using the fglrx 8.41 driver on this older graphics hardware will allow for a sizable performance improvement compared to the older binary drivers. Much of AMD's focus is on the R500 and R600 series, as is our focus, but we've completed some benchmarks comparing the new and old fglrx drivers using an ATI Mobility Radeon X300 64MB and ATI Radeon X800XL 256MB graphics card.
While many thought this day would never come or that it was some form of propaganda, it's coming and it's coming this month. The AMD fglrx 8.41 driver features a brand new underlying code-base that has been under development for well over a year. At Phoronix we have literally spent hundreds of hours using and testing this new driver, and to say the least it is truly a new experience on the ATI Linux front. The new driver delivers massive performance improvements, Radeon HD 2000 (R600) support, and a whole lot more. This article is the first of five articles that will be published today at Phoronix as we examine the new AMD Linux driver extensively on all fronts from seeing how it can handle the flagship ATI Radeon HD 2900XT graphics card to going back to past graphics card families to show the dramatic performance improvements.
On the Phoronix Forums we have been running a Q&A with the developers of the Nouveau project. For those out of the loop or new to Linux, the Nouveau project aims to provide an open-source 2D/3D graphics driver for NVIDIA hardware. After collecting a number of questions from our readers, KoalaBR and Marcheu have answered these questions. The questions range from whether there will be open-source SLI support to asking if NVIDIA has ever contacted the Nouveau developers.
Back in April of 2006, a proprietary driver from ATI that had supported the Radeon X1000 "R500" product family had finally greeted Linux users. This driver, v8.24.8, had supported the entire desktop and mobile Radeon X1000 lineup with 3D support and even Avivo video playback capabilities. For the six months prior, Linux users were stuck in the dark without any Linux support for the R500 series while the ATI Windows Catalyst customers had support that was continually improved. Of course, back in 2006 there was no open-source R500 driver either. Over the past 16 months with R500 support in the fglrx driver, the features have continually improved with an AMD Catalyst Control Center for Linux, support for the newer R500 graphics cards, and there are far less bugs in the driver now then there was in the past. However, these changes really have not affected the performance as it has stayed the same for the most part with minimal improvements. In this article today we are going back to test the original 8.24.8 display driver and compare it directly against the latest driver available as of today, the 8.40.4 fglrx release.
Scheduled for release tomorrow is X.Org 7.3. Among the new features for X.Org 7.3 include the Xorg server 1.4, an application for adjusting a display's backlight, updated display drivers, and support for font catalog directories. Version 1.4 of the X.Org server contains such features as RandR 1.2 support, input hot-plugging, KDrive enhancements, Solaris DTrace support, and EXA improvements. In this article today, we will briefly go over some of the changes found in X.Org 7.3 and we will follow up with some benchmarks in early September.
One of the new features to land with Ubuntu 7.10 Gutsy Gibbon Tribe 5 is the displayconfig-gtk. This new GTK control panel is similar to NVIDIA's nvidia-settings panel and ATI's Catalyst Control Center, which allow for GUI-based modifying of your xorg.conf to control such options as the display resolution, setting up multiple display heads in either an extended mode or mirroring, and changing your graphics driver. In this article, we are taking a brief tour of this early displayconfig-gtk application.
Through a joint effort between Phoronix and the Nouveau project, we will now be publishing the Nouveau Companion on Phoronix to update the progress made by these developers working on an open-source display driver for NVIDIA's complete selection of hardware from the NV0x chips to the latest models in the GeForce and Quadro series. This is the 26th edition of the Nouveau Companion which provides an updated status on the Nouveau driver with the progress being made in the areas of X-Video, video overlays for the different NVIDIA GPU series, and renouveau-parse for parsing XML dumps. These developers still need help especially with the NVIDIA GeForce 8 series hardware.
Thanks to recent commits in the RandR 1.2 branch for the open-source X.Org Radeon driver, it's now possible to use S-Video and composite TV output on your ATI graphics card without any patches. This is not limited to the R200 series but will also work with the R300 series and theoretically any graphics card supported by the xf86-video-ati driver. In this guide have outlined the instructions for enabling TV output support from the Radeon driver git code as well as some of the current limitations.
Last month marked the introduction of Fedora 7 support with the fglrx 8.39.4 ATI/AMD driver but not much more than that was to be found aside from an undocumented XML file. This driver did also present watermark problems that led to the driver being recalled and a corrected driver being pushed out. Today the fglrx 8.40.4 driver has been released and while many had speculated the 8.40 series would mark the introduction of the new Linux driver code-base, that's not the case for 8.40.4 driver. What changes does the 8.40.4 driver hold in store for Linux users? We'll tell you today but there isn't much.
Jerome Glisse and his posse of open-source developers have been making good progress with an open-source "Avivo" graphics driver for the ATI Radeon X1000 (R500) series hardware. However, one roadblock they have hit along the way is with TMDS setting issues on the Radeon X1200, X1300, X1400, and X1900 series. This roadblock had also led to postponing the Avivo 0.1.0 release. Now if you are an ATI R500 owner and have been wondering how you can help with the advancement of this open-source driver, there is a way even without prior development experience and that is by providing VBE mode-setting BIOS dumps. As you have probably never created such dumps before, we have written a brief tutorial on using vbespy/vbetest for the first time.
Since publishing our Avivo versus fglrx driver GtkPerf benchmarks that compared the GTK performance between the community open-source driver and ATI's official driver, we have received a number of requests for more of these 2D benchmarks with different graphics cards and different drivers. While this is not one of our formal articles, we have completed a few more GtkPerf tests with NVIDIA and ATI graphics cards to see how the GTK performance stacks up.
If you have been reading our ATI/AMD Linux display driver reviews for some time, you will know that there are periods where it doesn't look like the fglrx driver is actively being worked on, but in fact changes are being made "under the hood". We are going through one of these droughts right now where not many new features or bug fixes are being introduced, though a lot of work is going on internally. We have decided to dissect the last 19 months of driver releases from ATI/AMD to expose some interesting facts and what should be coming in the future.
Last month was an interesting time for AMD and their ATI Linux display driver. The Radeon HD 2400 and 2600 series were introduced, but as we have unfortunately come to expect, there was not a supported R600 driver that day or even that month. In fact, there still is no Linux driver to support any graphics card in the R600 series. Though making the month unique were two display drivers being released in the same week. The 8.38.6 driver had introduced Red Hat Enterprise Linux 5 support as well as some minor fixes, but nothing to spark interest in the minds of end-users. The second Linux driver released, 8.38.7, had come down the pipeline as a hot-fix release to correct a bug where aticonfig would crash and remove your xorg.conf. Moving forward to the 8.39.4 driver released today, we still have no AIGLX or R600 support, but we do have Fedora 7 support!
While the Avivo driver doesn't yet contain 3D functionality or support a number of features found in the official fglrx driver and the community Radeon driver, it is making steady progress despite its age. Most recently with the open-source R500 driver implementing shadow frame-buffer support, we have experienced a noticeable increase in performance. As we have begun to receive messages from those interested in this driver wondering about the performance capabilities, we have carried out a brief GtkPerf test comparing the Avivo git code to ATI's official binary "fglrx" display driver.
It was just a month ago that the open-source Avivo driver for the ATI Radeon X1000 (R500) series was introduced to the public, but in this time we've seen some great progress made. This open-source R500 driver now contains RandR 1.2 support, support for a variety of R500 graphics cards, and most recently support for Shadow Framebuffer was added. The Avivo driver still isn't comparable when it comes to the features found in the fglrx driver or even the open-source Radeon driver for the R200/300/400 series, but it's a work in progress. If you are running into problems with the fglrx driver, stuck using the VESA driver for one reason or another, or just want to get rid of the binary blob and experiment with this open-source driver, we have written a guide for setting up the Avivo driver from source on Ubuntu.
It was earlier this month that version 2.1.0 of the xf86-video-intel driver was released, which among other things had introduced open-source Linux graphics support for the G33, Q33, and Q35 chipsets as well as fixing a horde of bugs and adding PCI IDs for the 945GME, 965GME, and 965GLE chips. As our last Intel graphics performance article was looking at the Q965 back in May, in this article we have enclosed some benchmarks from Intel's GMA 950 IGP using the new xf86-video-intel 2.1.0 driver.
