No. 2.6.22/x86 introduces some drastic changes into the timer infrastructure Xenomai needs to cope with. Since v2.3.x is a stable series, it would not be possible to change its core the way Linux requires for supporting 2.6.22 and beyond; the changes would be too significant. So adeos-2.6.22 is only available starting from 2.4-rc1, because we may change the core Xenomai infrastructure appropriately there, and did so. > Or is the 2.3.3 limited to those Adeos patches that are part of the 2.3.3 > release? > v2.3.3 is limited to 2.6.20 and earlier for x86. The situation may be different for other archs, like powerpc for instance which may use more recent kernels. > If it is possible to use the adeos-ipipe-2.6.22 patch, what risks could be > caused by this > "not official" patch? Which patch are you referring too? Xenomai always uses official Adeos patches, and 2.6.22-1.9-01 is also available from the official Adeos download area. Those are the very same patches. > > Or more general: What is the relation between Xenomai and Adeos patches? > Are the Adeos patches used (and tested) somewhere outside of Xenomai? > Or is it always the bundle Adeos + Xenomai? > Adeos and Xenomai projects have the same lead maintainer, i.e. /me, which somehow simplifies a number of things for users since I tend to make sure Adeos will always fullfil Xenomai's needs, but makes them conversely complex for me. This said, Xenomai and Adeos are distinct projects founded at different times, even if in practice, Xenomai is Adeos's privileged user. I know of several projects using Adeos or part of under the hood, with or without RT extension on top, but patch validation is always conducted with Xenomai on top. > Thanks for a clarification. > > Regards > > Mathias > > > > > -- Philippe. _______________________________________________ Xenomai-help mailing list [email protected] https://mail.gna.org/listinfo/xenomai-help
