Open-Source Qualcomm Graphics Support Continues Flourishing With Freedreno

When it comes to open-source ARM graphics drivers, the Raspberry Pi / VC4 effort and Freedreno continue to be the two best examples of fully open-source graphics driver coverage including 3D support. Freedreno has been attracting contributions from Qualcomm / CodeAurora in what started out as solely a community reverse-engineered effort and with the latest-generation Adreno 600 series hardware the open-source support is in great shape.
