NVIDIA Posts Open Source 2D Driver Code
 

After launching its high-performance display driver for Linux that boosts GeForce graphics performance by 100%, NVIDIA released an open-source 2D driver code for its Tegra 2 and Tegra 3 SoCs, which is based on the experimental Direct Rendering Manager driver (DRM, not as in digital rights management). DRM was started as an independent project by Thierry Reding, but is now being worked on by NVIDIA, among others.

The open-source DRM driver code published by Terje Bergstrom today provide host1x and 2D on Tegra 2 and Tegra 3 SoCs, and was published by Terje Bergstrom. He writes "nvhost is the driver that controls host1x hardware. It supports host1x command channels, synchronization, run-time power management and memory management. It is sectioned into logical driver under drivers/video/tegra/host and physical driver under drivers/video/tegra/host/host1x. The physical driver is compiled with the hardware headers of the particular host1x version."
