Linux on ARMSamsung has published the code to a new open-source DRM driver for its EXYNOS4210 System-On-a-Chip. The EXYNOS4210 has impressive 3D graphics capabilities, uses the dual-core ARM Cortex A9 processor, and is used in various smart-phones. The Samsung Galaxy S II is one of the smart-phones using the Exynos 4210 SoC. Samsung is hoping to push this DRM driver into the mainline Linux kernel.

Samsung engineers previously released two revisions of this driver code, which received some feedback from developers over the past month, and they have now released the polished (third version) that incorporates the changes. This Samsung DRM driver with kernel mode-setting support uses the Intel GEM (Graphics Execution Manager) for buffer management and DMA APIs for buffer allocation. FIMD is only supported right now but HDMI support is said to come at some point in the future.

It's not clear though whether this Samsung EXYNOS driver will be accepted into the mainline Linux kernel tree since there doesn't appear to yet be any open-source user-space side with an X.Org DDX driver, Gallium3D driver, or anything similar.
