These GIT trees were hosting the development of legacy Xenomai
releases. Their contents have been merged into the current
development tree for version 3.x
as eol/v2.x.y branches, along with the legacy release tags.
An ancient port of the RTDM interface to the native kernel API, based
on an obsolete Xenomai release which dates back to 2007. Not
maintained since then.
These trees were maintained by Gilles
Chanteperdrix, a core
maintainer who contributed to every aspect of Xenomai since the very
early days of the project, most notably to the ARM support.
