Integrated kernel patch for improved AMD and Intel graphic

The Linux 2.6.38 was integrated with a wonder patch for minimizing Linux desktop response time and graphic drivers for Radeon HD 6000 graphic chips and economizing on power by the Graphic cores in Intel processors.

Linux in a bid to overcome the negative impact of build on desktop interactivity for CFS users, issued a patch for automatically creating task groups. However, there is a limitation as autogroups can be implemented only per session. But the patch is open for future enhancement.

To Ingo Molnar the maintainer of the process scheduler, the patch is one of the ‘biggest and most visible interactivity improvement by the Linux scheduler’. Several functions and operations that you will need to be aware of – like maintaining the status of the auto grouping through the ‘noautogroup’ kernel boot parameter at the booting stage are very critical when working with the patch. The patch is integrated with the Linux 2.6.38

Additional optimized features

The Linux 2.6.38 already contains about one-fourth significant changes in terms of the source code, management system already being included in it. The graphic support is provided for AMDs Ontario and Zacate Fusion processors running on Bobcat cores.

Linux enabled for AMD

AMD too has released patches to extend the kernel’s Radeon DRM driver for the 6000 to 6800 Radeon HD models northern Islands graphic chip. All these features are available on the Linux 2.6.38 and expected for release by April. These will enable 2D as well as the 3D support for the graphic cards.  The userspace code is already enabled with the developer versions of Mesa3D as well as the xf86-video-ati package.

Northern Island chips can be set only through KMS

The Northern Islands chips cannot be set on the User Mode Setting on the X Server. The Kernel-based Mode Setting or the KMS is compulsory for the new Northern Islands. These events were very similar in occurrence with the earlier versions of the Radeon HD series such as the 5000 series that were known by the name of Evergreen. An earlier release was the Cayman chips on the HD Radeon HD models 6950 and 6970 for which the support is yet in the development stage and needs to be submitted yet.

The merged patch on the Linux 2.6.38 supports AMDs GeForce as well as the earlier mentioned Radeon graphics cards. It also supports AMDs new Fusion CPU. Additionally tremendous powerful features for economical use of power at the graphics cores with the Intel processors as well as the chip-sets are worthy of comment.

Graphics features enhanced

The entire gamut of graphics related features have been fixed with this patch and hence have acquired the sobriquet ’wonder patch’. It vastly improves on the basic features of stopping images flickering every time a new page is flipped. Now with the integration of the new patch features, it has greatly minimized the torn edges and tearing effects and has vastly improved the incomplete rendering issues that were being to wear thin with the user.
