Welcome to the Linux/Xtensa Wiki

This Wiki project provides information for running and porting Linux and other Open Source Software to the Xtensa processor architecture.

The Xtensa processor architecture is a configurable, extensible, and synthesizable 32-bit RISC processor core. All Xtensa processors share a common base instruction set architecture, thereby ensuring compatibility of third party application software and development tools. Many architecture specific projects, such as the Linux kernel, GNU toolchain, and other development tools and applications already support the Xtensa architecture. Modifications to support a specific processor configuration are limited to a small set of configuration files, and the process is mostly automated. The pages listed under Supporting a processor configuration provide information to support a specific configuration.
