Kernel Log: What's new in 2.6.29 - Part 3: Kernel controlled graphics modes

Filed under
Linux

With the release of 2.6.29-rc1 last weekend, Linus Torvalds concluded the first phase, called the merge window, of the development cycle. This phase allows for incorporating the substantial changes intended for the next kernel version into the source code management system of the Linux kernel.

As a result, 2.6.29 is now in the second, stabilising phase, which usually takes eight to ten weeks and gives the kernel developers the opportunity to correct mistakes and make minor changes that are unlikely to cause further flaws. As major changes are only rarely discarded during the stabilising phase, the kernel log can already discuss the most important changes expected for 2.6.29 in the "What's new in 2.6.29" series.

Kernel-based mode setting

Almost 21 months after its first major announcement, the support for kernel-based mode setting (KMS) for recent Intel graphics hardware has been integrated into the main development branch of Linux (for example 1, 2, 3). This technology gives the kernel noticeably more control over the graphics hardware. When KMS is active, the kernel sets the graphics mode suitable for a monitor as soon as all the required hardware components (ACPI, PCI, graphics hardware etc.) have been initialised.

FSF's High Priority Project List Now Has A Committee

The Free Software Foundation has now built up a committee to review their "High Priority Projects" list and they're looking for more feedback from the community. Nearly ten years ago is when the Free Software Foundation began listing what they viewed as the High Priority Free Software Projects in a list. This list has over time contained some definite high-priority projects related to freeing Java and Adobe PDF support and open graphics drivers to some more obscure projects of high priority like a free version of Oracle Forms, a replacement to OpenDWG libraries for CAD files, automatic transcription software, etc. I've personally called out many of the FSF HPP for what they're worth with my thoughts over the years.
