The OpenSPARC T1 processor RTL was released under the GPLv2. In order to promote compatibility with a variety of communities (Linux, FreeBSD and OpenSolaris), some technology and tools will be made available under a BSD license. Other technology (particularly code contributed by third parties and certain tools) will only be available as binaries will only be available under a binary Software License Agreement. Finally, some components may be based on existing open source projects and these will be made available on the OpenSPARC website under their current licenses.
