X.org

The X.org project is working towards the next major release, with August seeing mostly minor releases of various X components. Most notably of these were the mesa 9.2 release, new -intel and -ati driver releases, and a second pre-release of a new stable Xserver.

The Xserver release candidate 1.14.2.902 includes half a dozen small bug fixes on top of the earlier .901 release, in preparation for the 1.14.3 stable release.

The two -intel driver releases includes some Haswell performance tuning, RGB overlay support for Ironlake and later, and various other fixes. Most changes were to the SNA code path.

The -ati release is significant, as this is the first release in some time. This adds PCI IDs and support for a huge range of newer ATI hardware (Sea Islands, Southern Islands, Richland, and Kabini APU), reverse prime support, 2d tiling support and glamor 2d acceleration for radeonsi, and various fixes and enhancements.

The Mesa 9.2.0 release was announced Aug 27th as a development release. This will be followed by a 9.2.1 stable release in the coming weeks. The main new feature in mesa 9.2 is the OpenGL 3.1 API, which is partially implemented by several drivers.

Mesa 9.1.6 was a bug fix release which provides fixes to crashes, rendering corruption, etc.

Following these releases, Mesa development has focused on glsl, clover, geometry shader support for gen7 Intel, radeonsi cleanup, gallivm fixes, and other assorted code base cleanup.

Beyond Mesa and video drivers, the core X.org development these days is mostly maintenance, refactoring, and cleanup work. Adam Jackson put attention to cleaning up rootless code, various janitorial cleanups, and piglit test fixes. Eric Anholt put attention into Xephyr, migrating code to XCB and removing dead or obsolete code. Last month we looked at the ongoing new DRI3 work.

Wayland

The Wayland project comprises two code trees: 'wayland', which is just the protocol definition, and 'weston', the demo compositor that implements the backend server for the protocol.

Weston 1.2.1 was released on August 22nd this month, followed by 1.2.2 a week later to fix four serious regressions. Wayland 1.2.1 was released on August 22nd as well and is the current stable release; it provides cherry-picks of fixes since 1.2.0, documentation improvements, and addition of touch support to the move API.
