Tegra/SoCs

Many NVIDIA Tegra SoCs are supported by mainline OSS software. This page provides a few details of each SoC.

Each SoC has an engineering name (typically TegraNN where NN is some number) and a marketing name (typically "Tegra XX" where XX is some name or number). Software typically uses the engineering name for the chip in order to be isolated from marketing decisions. This wiki primarily uses the engineering names, but this page lists both in order to allow mapping between the two.

See the Tegra resources page for links to Soc documentation etc.
