Besides the DRM work already piling up for Linux 3.4, there's more. The Samsung developers responsible for the Exynos graphics driver have sent in their "-next" pull request, which brings several new features, including the basis of 2D acceleration for this open-source ARM graphics driver. There's also a virtual display driver that could be used for handling wireless displays.
Inki Dae of Samsung fired off an email with ten patches this morning to David Airlie that includes the exynos-drm-next work. Notable changes to the Exynos DRM driver slated for the Linux 3.4 kernel include HDMI version 1.4 support, a buffer allocation type to allocate physically continuous or non-continuous memory, a new DMA address get/put interface needed for GEM/2D acceleration handling, a virtual display driver, and a direct-rendering 2D graphics acceleration module.
