Hi We are developing an operating system on top of Pistachio. At the moment we are looking for a framework which would allow to quickly port existing device drivers (e.g., from Linux) to our system as well as develop our own drivers. L4Env with its Omega0 server, l4io library and DDE seems to be a perfect match. Unfortunately, L4Env does not currently support Pistachio. L4hq site says that such support will follow shortly. Is this work being carried out, and, if so, when (approximately) will X.2-compatible L4Env be released? Thanks in advance. Leonid
