Versie 2.6.39 van de Linux Kernel is vrijgegeven. De kernel is het hart van het besturingssysteem en zit, simpel gezegd, als laag tussen de hardware en de applicaties in. De changelog voor versie 2.6.39 is nog niet bijgewerkt, maar uit een artikel bij Heise Media kunnen we opmaken dat er diverse verbeteringen voor grafische kaarten zijn aangebracht, voor AMD, Nvidia en Intel.
Linux 2.6.39
The Radeon driver of kernel version 2.6.39 will support the Cayman family of graphics chips that AMD is using, models such as the current Radeon HD 6790 to 6970 cards (see 1, 2). However, these cards' 2D and 3D acceleration features are unavailable because there is no DRM support; future kernel versions will fix this problem.
The Nouveau driver for NVIDIA GPUs now supports Z compression. The developers have also fixed a performance issue that reportedly reduced performance by 10 to 30 per cent.
The developers of the graphics drivers for Intel chips have made numerous minor changes; some of them reduce the power consumption of recent graphics cores (see 1, 2, 3) or improve performance in certain situations. The developers have added a rudimentary graphics driver for the GMA500, a graphics device that was previously considered a big problem under Linux. It is included in Intel's US15W ("Poulsbo") chipset, which was originally designed for the embedded market but is used in netbooks by some manufacturers.
