Less than a year ago we shared with you the revolutionary steps AMD was taking to deliver significant improvements to their once infamous proprietary Linux display driver and at the same time the work they were doing to foster the growth of an open-source driver for their latest graphics card families. These steps have certainly paid off for both AMD and the Linux community at large. AMD's proprietary driver is now on par with NVIDIA's Linux driver and there are two open-source ATI drivers picking up new features and improvements on an almost daily basis. AMD also continues to publish new programming guides and register information on a routine basis for their latest and greatest hardware. This has been truly phenomenal to see, but AMD has now evolved their Linux support by taking it a large step further. AMD is in the process of pushing new high-end features into their Linux driver -- such as Multi-GPU CrossFire support -- and with the ATI Radeon HD 4850 they have even begun showing off Tux, the Linux mascot, on their product packaging and providing Linux drivers on their product CDs!
In AMD's usual fashion, this afternoon they have announced the release of new display drivers for both Linux and Windows. The Catalyst 8.6 release for Linux introduces a few bug fixes, version 2.0 of their driver installation API, and a few unannounced features are present. As always, we have the run-down for you on this month's changes.
Following our article looking at the state of X.Org (along with announcing the release of X Server 1.4.1), we proceeded to share the contributors behind the X Server -- both the individual developers and companies involved with fostering the growth of this important free software package since 1999. What we hadn't looked at in that analysis was the people and companies behind the work on Mesa 3D, or the OpenGL component used by X. In this article, however, we have these statistics to share.
Late last month AMD had announced the release of the Stream SDK for Linux. This Stream SDK brings support for the CAL and Brook+ libraries on Linux. The version released was Stream SDK 1.1 Beta, which arrived at the same time as the SDK for Windows XP. With this new Linux support, we ran a small Q&A session with Michael Chu, who serves as the product manager for AMD Stream software. In this article are AMD's answers to some of the questions asked by members of the Phoronix Forums.
NVIDIA's last Linux display driver release was just shy of two months ago when they had unveiled the 173.08 Beta driver with compatibility for the GeForce 9800 series and other new GeForce 9 parts. Prior to the 173.08 release was version 171.06, which was another beta release, and the last official release being NVIDIA 169.12 from February. NVIDIA this morning has released the 173.14.05 driver, which marks the return to their old naming convention, but it doesn't bring many changes compared to the recent beta releases and just a regurgitated release announcement.
From the release of Mesa 7.1 Release Candidate 1 to Multi-Pointer X being merged to master to the R500 3D milestone, it's been an exciting past 24 hours for the X.Org community. With the open-source 3D support for the Radeon X1000 "R500" GPUs now reaching a parity with the Mesa support for earlier ATI Radeon product families, more Linux users can now consider turning to an open-source driver (xf86-video-ati or xf86-video-radeonhd) for their video driver needs. In this article we are looking at what Linux games work thanks to this latest Mesa R500 support.
While the RadeonHD developers have been busy working on Radeon HD 3200 / 780 Series support and other features for this open-source ATI R500/600+ driver, the DRM (Direct Rendering Manager) support has been lagging behind. Earlier this month Matthias Hopf was successful in getting DRM working on an RS690 GPU and he has published RadeonHD DRM code into his personal development tree, but no code has yet to reach master. Meanwhile, as the xf86-video-ati driver is using AtomBIOS, they are able to spend more time working on the 3D features and other areas and less time "banging on registers" or even waiting on register documentation to arrive. David Airlie has been working on the R500 3D support along with Alex Deucher and Corbin Simpson. The trio has been making some great headway towards open-source 3D goodness for Radeon X1000 and HD 2000/3000 GPUs. Their most recent efforts have focused around the R500 fragment program code and today they have reached a monumental milestone.
The AMD 780 Series Chipsets have been available for nearly four months now, and supporting the Radeon HD 3200 graphics since day one has been AMD's proprietary Catalyst driver. On the open-source side, there has been the Radeon HD 3200 / 780G support quite quickly through the xf86-video-ati driver due to its use of AtomBIOS, but the support within the RadeonHD driver hadn't arrived until earlier today. Thanks to 22 code commits made to the mainline xf86-video-radeonhd git tree, it's now possible to use this newest AMD integrated graphics processor with this Novell-spawned driver.
Earlier this month we announced that AMD would soon be releasing their Stream SDK for Linux, and just before the start of the weekend this inaugural release had occurred. The Linux release of the AMD Stream SDK v1.1 Beta brings both CAL and Brook+ for those using ATI/AMD graphics hardware. This v1.1 Beta release is also in tune with the new beta release for Microsoft Windows XP.
All of the Catalyst Linux driver releases this year have been... well, boring. There have been a few bug fixes in each release and new product support for the latest ATI/AMD GPUs, but no major features have been introduced in several months. However, during this time we've been telling you to get ready for an interesting summer and that "we have reason to believe AMD does have some Linux work under development that could make 2007 look boring compared to this year." It was in 2007 that AMD had introduced their brand-new driver with AIGLX support. Well, with the release today of Catalyst 8.5 the monthly Linux driver releases are becoming more interesting and we should have several exciting months ahead. What does today's Linux driver bring to the table? We'll give you the run-down in this article, but to get you started there is now Catalyst AI, Linux 2.6.25 support, and much improved 2D performance!
In the 39th edition of the Nouveau Companion, this open-source NVIDIA driver development crew talks about their latest driver achievements over the past few weeks. Among the progress made includes further enhancing the NV50 support, a Nouveau XvMC implementation for Gallium3D (initially through a software-based implementation), and MMioTrace being postponed to the Linux 2.6.27 kernel.
Last month we reported on VIA's new open-source driver efforts that was announced at the LF Austin Summit. This new strategy involves VIA providing the open-source community with NDA-free hardware specifications, code, and other resources -- in a similar fashion to what ATI/AMD and Intel have been doing for some time now. However, not everyone has been satisfied by this announcement and their new Linux website isn't yet exactly useful. We explore the VIA Linux situation in this article as well as sharing what two open-source developers have to say.
There are many new and innovative features brewing within the X.Org development community right now -- among the many are Gallium3D, the TTM memory manager, and MPX (Multi-Pointer X) -- but one of the features that has risen towards the top of the list and delivers visible benefits to the end-user is kernel-based mode-setting. As implied by its name, kernel mode-setting involves moving the mode-setting code for video adapters from the user-space X server drivers into the Linux kernel. This may seem like an uninteresting topic for end-users, but having the mode-setting done in the kernel allows for a cleaner and richer boot process, improved suspend and resume support, and more reliable VT switching (along with other advantages). Kernel mode-setting isn't yet in the mainline Linux kernel nor is the API for it frozen, but Fedora 9 shipping next month will be the first major distribution carrying this initial support. In this article we're looking more closely at kernel mode-setting with the Intel X.Org driver as well as showing videos of kernel-based mode-setting in action.
In the last quarter of 2007 AMD was on a spree with their proprietary Linux driver as they introduced their new OpenGL driver, which brought major performance improvements, and that was followed by AIGLX support. This year, however, their Catalyst Linux driver activity has been relatively quiet for end-users. Since switching over to this much-improved code-base, they have been able to deliver same-month product support for their new graphics processors such as the Radeon HD 3650, 3850/3870, and the 780G-based IGP, which once couldn't be said for this company that had taken them a half-year to deliver support for the Radeon X1000 (R500) and Radeon HD 2000 (R600) product families. Today the Catalyst 8.4 Linux driver has been released, and like the 8.1, 8.2, and 8.3 drivers, this month's update comes with minimal changes.
Last week it was exclusively reported by Phoronix that a new NVIDIA binary Linux display driver should be out in the next week, and sure enough we were right, again. The NVIDIA 173.08 Linux driver was released last night and features support for several new NVIDIA GPUs, including the GeForce 9800 series, experimental support for X Server 1.5, and a number of fixes with Linux 2.6.25 kernel compatibility.
It's been a long time in the making, but the xf86-video-radeonhd 1.2 driver has just been pushed out the door. RadeonHD 1.2 is the first new release for this open-source ATI R500/600 driver since December of last year. The RadeonHD 1.2 driver includes support for new AMD graphics processors, 2D XAA/EXA acceleration, and other changes.
Announced this morning at the second annual Linux Foundation Collaboration Summit is a new open-source driver development initiative. VIA Technologies has announced its strategic open-source driver development initiative. VIA will be providing technical specifications, source-code, and other information regarding their latest products. In addition, they'll be opening a new web-site devoted to its new Linux efforts.
In the first Nouveau Companion this spring, the free software developers reverse-engineering the NVIDIA Linux driver have provided a new status update. Most of the progress recently made to this open-source X.Org driver is for the NV50 GPUs found on the GeForce 8 and 9 series. There is a new test program for directly communicating with NV50 processors and that these newer graphics cards have reached the milestone of being able to render an object with this driver. Approaching soon is supporting the TTM memory manager with Nouveau. The open-source Nouveau developers are hoping to get some Google Summer of Code students working on XvMC support and suspend-and-resume along with a simple Gallium3D backend for the NVIDIA NV2x ASICs.
In the thirty-seventh edition of the Nouveau Companion, the topics covered largely come down to Gallium3D, the status of the Nouveau driver for each of the NVIDIA product families (primarily the GeForce 8 series), and of interest is that RandR 1.2 should soon be enabled by default for this reverse-engineered open-source 2D/3D NVIDIA driver. The Nouveau developers are working on Gallium3D extensively and recent David Airlie had tried the Nouveau Gallium3D driver for PowerPC, but there is a problem with depth buffers. The GeForce 8 (NV50) status is continuing to improve but there's still work to be done, as these GPUs have no NV40 compatibility mode. Read the rest in this edition of the Nouveau Companion.
Coming just a day after AMD had opened up their production microcode from their proprietary drivers for the R100 to R600 GPUs, a significant milestone has been reached in the road to open-source 3D graphics capabilities for the Radeon X1000 (R500) series. We now have hardware-accelerated glxgears!
In the next step towards open-source 3D support for the R500 and R600 GPUs (Radeon X1000 and Radeon HD 2000/3000), AMD has just pushed its production microcode into the Mesa/DRM git tree. This is the microcode found in the fglrx driver and it covers the Radeon R100 to R600 product families.
For Linux distribution vendors, right now is proving to be an awkward time for them as they decide which ATI driver will ship as the default choice in their spring distribution refresh. The problem used to be whether to ship a binary-only driver in the distribution in order to provide "out of the box" support for all available graphics hardware, but on the ATI/AMD side the software distributors are now facing the challenge of which open-source driver they should call the de facto standard. In this article we are briefly looking at the matter of the xf86-video-ati vs. xf86-video-radeonhd drivers, the highly political issue of AtomBIOS, and what some of the popular Linux distributions are deciding to use this spring.
Last month right before FOSDEM 2008, the 3D programming documentation for the R500 GPUs (Radeon X1000) series was released. This documentation consisted of a register reference guide for the R500 GPUs as well as a programming guide covering such areas as the command processor, vertex shaders, and fragment shaders. While the register reference guide for the R600 series is still being worked on, for those with older ATI graphics processors, AMD has went back and created a register reference guide for the R300 series.
Following a period of relative inactivity in the xf86-video-radeonhd git tree over the past few weeks, this afternoon Novell's Egbert Eich had pushed forward 55 changes to this open-source R500/600 driver. The AMD Radeon HD 3400 and 3600 series are now supported and there are a number of other significant changes. The RV620/635 mode-setting support has required the most significant work since the R500 series, since all output blocks have been altered due to the introduced DisplayPort capabilities. We have already tested out this latest code and were left with a positive impression.
On the same day as the limited open-source support arriving in the xf86-video-nv driver, NVIDIA's binary display driver for Linux has been updated to officially add support for the GeForce 9600GT graphics card. This new driver update is version 171.06 (Beta) and its only change is the added 9600GT support, but that's compared to the 171.05 driver that was targeted specifically for the Tesla S870.
Last month with the Catalyst 8.02 Linux driver we mentioned just how low on the end-user changes the fglrx driver has been in recent months, and today the Catalyst 8.3 Linux driver has been released with the release train slowly chugging along. The only new feature in this month's proprietary Linux driver is X-Video support for the Xpress 1200 hardware, but there are a few bug fixes that may satisfy some Linux users.
With FOSDEM 2008 taking place about two weeks ago, the 36th edition of the Nouveau Companion contains a special feature with FOSDEM-Nouveau coverage as well as in-depth thoughts from the developers that had attended this Linux conference in Brussels. Also covered in this development newsletter is new Gallium3D progress in their mainline Nouveau branch, MMioTrace is still planned for the Linux 2.6.26 kernel, and more RandR 1.2 improvements within this free software NVIDIA driver.
It was a year ago that AMD had replaced its aging FireGL Control Panel inside its Linux driver with the AMDCCCLE, or AMD Catalyst Control Center Linux Edition. Since that time, this Catalyst Control Center for Linux continues to mature with a few new features being added here and there, and version 2.0 could in fact be introduced in an upcoming release. At the same time, the control panel utility that ships with NVIDIA's binary driver, nvidia-settings, has stayed more or less the same for the past few years with only a few minor revisions. How do these two Linux control panels compare though when it comes to the features? For this article we have put AMDCCCLE and nvidia-settings side-by-side to compare and contrast both utilities.
We know NVIDIA has been working on a new Linux display driver release, with the GeForce 9 series having been introduced just this past week, and today a new driver release has arrived for Linux, Solaris, and FreeBSD. However, this new 169.12 display driver doesn't introduce support for the GeForce 9600GT and its official changes are limited to maintenance items.
This afternoon at FOSDEM 2008 in the X,Org development room, Keith Whitwell of Tungsten Graphics had provided a status update on the Gallium3D graphics driver architecture followed by Jerome Glisse talking about his work in porting the Radeon driver from DRM to Gallium3D. Jerome had also commented on other Radeon/X.Org topics such as kernel mode-setting. In this article are Gallium3D notes from these two talks.
