Google selects RTEMS Atomic Operations and SMP lock debug tool for RTEMS as their feature project on the Google Summer of Code webpage. This project is continuation of last year GSOC project. In the last year the architecture-independent atomic API has been developed and the implementation of X86 and PowerPC has been completed. So in this year the project’ goal is to support all other architectures. The task includes that a general atomic ops should be defined to support all the architectures which do not support SMP mode.
