Do you mean there is something more recent than ltt-0.9.6-pre4 ?

This restrain then to use oldgen Adeos architecture, as LTT is only available on 2.6.9 and ipipe only from 2.6.13; is there anything preventing having ipipe on 2.6.9 (apart from workload of course)? > Upgrading this combo will be done in the I-pipe 1.1 > timeframe over the > newest LTT support, for sure, basically to get rid of the > oldgen Adeos patches > for Xenomai completely.

BTW the rapid evolution of 2.6 is perhaps a benefit for some people, but to maintain kernel-dependent extensions, it seems to be more a nightmare than anything else... > -- > > Philippe. > > Bernard _______________________________________________ Xenomai-core mailing list Xenomai-core@gna.org https://mail.gna.org/listinfo/xenomai-core
