New xf86-video-intel 2.10 Testing Release

,----[ Quote ]
| Less than two weeks ago the first release 
| candidate for the xf86-video-intel 2.10 
| driver was released, but now the second 
| release candidate can be obtained from its 
| Git repository. Not a whole lot of work has 
| been committed to the Intel DDX driver 
| since xf86-video-intel, but 
| is out there and testing is 
| appreciated. 


What Will Happen To xf86-video-nv In 2010?

,----[ Quote ]
| While the Gallium3D driver to provide 
| 3D/OpenGL acceleration (along with OpenCL, 
| OpenVG, OpenGL ES and other accelerated 
| APIs through the state tracker interface) 
| will not be released right away as this is 
| where the bulk of the development is still 
| taking place, the Nouveau driver already 
| has many advantages over what it is 
| replacing: xf86-video-nv. The xf86-video-nv 
| driver is NVIDIA's attempt at an open-
| source driver in the way of just providing 
| very basic user mode-setting for their 
| hardware and limited 2D acceleration. 
| That's about it for the features of this 
| driver with no RandR 1.2 support or any 
| other DDX features found in most other 
| drivers. 


The Nouveau Pony Is Pulled, Ctx_Voodoo Ignored

,----[ Quote ]
| Leading up to this though, Red Hat 
| attributed Nouveau not entering the 
| mainline tree sooner on the basis of some 
| microcode/firmware concerns. Without 
| sorting out the issue for this mysterious 
| microcode, known as ctx_voodoo, they could 
| not sign off on the code. As of right now, 
| they haven't even fully resolved this 
| situation but they are just having 
| ctx_voodoo be loaded through the kernel's 
| firmware loader interface. However, we have 
| learned that ctx_voodoo is not even needed 
| for all graphics cards and that Red Hat was 
| just attempting to ignore this little fact. 


NVIDIA 190.53 Pre-Release Linux Driver

,----[ Quote ]
| For those not interested in the Nouveau 
| driver, head on over to NVIDIA's FTP server 
| as a new 190.xx driver is available. Late 
| last month NVIDIA released the 195.22 beta 
| Linux driver as the first in this new 
| driver series, and while there are new 
| features and advancements going on there, 
| NVIDIA is still maintaining the current 
| 190.xx stable driver series. Released last 
| night was the NVIDIA 190.53 pre-release 
| driver. 



Another Shot At The KMS Page-Flipping Ioctl

,----[ Quote ]
| This DRM ioctl patch touches about 400 lines of
| code (mostly the addition of new code) and is
| now
| hopefully ready to enter the Linux 2.6.33
| kernel, which is great news for those using the
| X Server and also those wanting to experiment
| with Wayland but have been waiting for more of
| the work to land in mainline trees. The Linux
| 2.6.33 kernel will be the first release in 2010.


OpenCL Over Mesa, Gallium3D Discussion

,----[ Quote ]
| While NVIDIA and ATI/AMD have OpenCL support
| within their binary drivers, the open-source
| Mesa / Gallium3D stack is still lacking
| open-source support for the Open Computing
| Language on Linux. But the discussion
| surrounding OpenCL in Gallium3D has been
| renewed on the mailing list today.
