ATI/AMD的开源驱动已经出了,支持HD系列

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.

To no real surprise, the RadeonHD driver is hosted over at FreeDesktop.org and you can checkout the latest code using git. In another article we are publishing today, we will be telling you how to install this new open-source driver on Ubuntu 7.10 Gutsy Gibbon -- that is for those of you who aren't familiar with using git or building drivers from source. If you haven't already, you'll also want to read AMD's Open-Source Strategy Explained.

The RadeonHD driver is largely being written by Novell/SuSE and they have been writing it for the past couple of weeks using the same documentation that was released freely to the open-source community last week. Novell developers will continue contributing to the RadeonHD driver as well. The specifications available to the community so far are just register reference guides for the RV630 and M56, but AMD will be releasing additional documentation (including for 3D functionality) once the documents are sanitized and then cleared by their legal department.

Don't expect any miracles from this driver just yet. At this point, the RadeonHD driver is really targeted for developers and those wanting to use the experimental driver whether it is due to problems using the fglrx driver on the system or just wishing to test out the driver to see if it works for you. As long as AMD sticks to their word on delivering the rest of their documentation, there will not be too much (if any) reverse engineering that needs to take place for the R500 and R600 series. However, the driver is still likely a few months out from a stable point for 2D users (perhaps in time for X.Org 7.4) and then the 3D work after that. Granted, depending upon how many X.Org community members end up contributing and the rate at which AMD pushes out new documentation, the timeline will certainly change. You can see comments by some of the known X.Org video driver developers in this article.

The availability today of the RadeonHD driver is certainly a step in the right direction, but there is much work left to be accomplished with this new open-source ATI/AMD driver. We will be publishing additional articles once we have had more time to check out and test the xf86-video-radeonhd driver, but in the mean time go check out the code and post what you think about the driver in the Phoronix Forums. While a RadeonHD mailing list will be established shortly, you can also visit the #radeonhd IRC channel on Freenode.

安装,没事做的可以试试:D

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. This guide is based off our Avivo on Ubuntu How-To.

Like the Avivo driver, RadeonHD requires X server 1.3 or newer. Ubuntu 7.04 Feisty Fawn ships with X server 1.2 while Ubuntu 7.10 Gutsy Gibbon (to be released next month) ships with X server 1.3. Therefore, you will need either to manually upgrade the packages in Feisty Fawn against a Gutsy repository or check out Ubuntu 7.10. For our purposes, we had installed an Ubuntu daily LiveCD on September 15, 2007. These installation steps are mostly the same no matter the Linux distribution (granted, the package names will be different), but in this guide we are focusing specifically on Ubuntu.

Well, the logical thing to do is to get the latest driver source-code. The RadeonHD driver is housed at FreeDesktop.org in git. Unless you already have installed the needed Ubuntu packages, you will need to execute the command displayed below. The command will install the needed packages for git and compiling the RadeonHD driver from source. Unlike the Avivo driver, the RadeonHD driver doesn't yet depend upon libpciaccess and therefore the libpciaccess-dev package isn't yet needed but will be at some point in the future.

sudo apt-get install build-essential git-core configure-debian automake autoconf xorg-dev libtool

Now that git is installed, execute the below command to check out the RadeonHD driver from FreeDesktop.org.

git-clone git://anongit.freedesktop.org/git/xorg/ ... o-radeonhd

Now that there is a copy of the RadeonHD code locally, it's time to build and install the X.Org driver using the below commands.

cd xf86-video-radeonhd/; ./autogen.sh --prefix=/usr/; make; sudo make install

After that, it's time to update the xorg.conf to reference this new driver. In the Section "Device" area that is showing vesa, avivo, or fglrx, change the Driver "<driver-name>" line to radeonhd.

代码: 全选

sudo gedit /etc/X11/xorg.conf


Since the RadeonHD driver doesn't yet support Composite/AIGLX, you need to manually disable them.

代码: 全选

Section "Extensions"
Option "Composite" "Off"
EndSection

Section "ServerFlags"
Option "AIGLX" "Off"
EndSection


After that, restart X and you should be good to go with the new RadeonHD driver (permitting you run into no driver problems). It's as easy as that. Before installing the driver, it is important to reiterate that this driver is still very basic and is definitely not ready for any production environments nor will it be for at least a few months. This new driver does use ATI's ATOM BIOS but there are still a number of R500 and R600 graphics cards in our tests where we had run into trouble with the latest xf86-video-radeonhd driver git code this afternoon. In this guide we had used a Radeon HD 2400PRO 256MB PCI Express graphics card. If you run into any problems or need help for your distribution, stop by the Phoronix Forums.

还是不支持啊

不支持混合太逊了。其实我要求不高,就混合就好了。

不过至少是开源了。比nv的好多了。很快应该就出来支持aiglx的开源,而且3d应该不会像以前那么不稳定了吧

开源的力量是伟大的。 :lol:
