Linux on ARMThere is another new open-source Linux graphics driver entering development and it has already showed signs of success with basic 2D acceleration working. This new open-source driver is for Qualcomm's Snapdragon / Adreno and who is leading the development of this driver is also quite interesting.

This new open-source Snapdragon graphics driver is the open-source GPU news I was hinting at earlier in the week. This driver now joins the Lima Project (the effort for an open-source ARM Mali GPU driver) as being a reverse-engineered Linux graphics driver for an ARM-based SoC. There's also the open-source Texas Instruments OMAP and Samsung Exynos open-source drivers, but while those are backed by their respective companies, they don't offer up accelerated support and are not fully open-source stacks.

What also makes this Snapdragon project interesting is who is the lead developer: Rob Clark. If the name does not ring a bell, you are not up-to-date on your Phoronix reading, but he is one of Texas Instruments' ARM developers. He is the one that is in large part responsible for the Texas Instruments OMAP DRM driver and through his involvement with Linaro has been taking part in DMA-BUF, extending DRI2, and other efforts. While Texas Instruments' OMAP competes with Qualcomm's Snapdragon in the ARM space, he's decided to work on reverse-engineering his competitor's graphics core in his free time.
