It looks like people have been rather busy with this one; here is what's new since -rc1, in no particular order: - The ARM port [Stelian]. This work has been co-sponsored by the Video Compression and Networking group from Thomson Grass Valley [2], and Openwide. This initial port has been conducted on an Integrator/CP board featuring an ARM 1136 core. - POSIX skin updates [Gilles]. - Allow building the kernel from within the Xenomai tree [Gilles]. This is for those who dislike having to deal with compiling the kernel and user-space trees separately. - Major bug fix regarding the hybrid scheduling feature, i.e. the ability to make transitions between kernel-based and user-space Xenomai threads [me, Heikki]. Basically all archs are concerned by this fix, but x86 which had no problem regarding this issue. As Heikki put it once rather politely in the light of such a mess, "A good test-suite seems like a must". Ahem, yeah... - Provide support for 2.6.15/x86 [me]. Other archs will follow. - Upgrade to the most recent I-pipe series for all archs, allowing to shorten the interrupt path a bit [Dmitry]. - RTDM-based benchmark suite [Jan]. Our good ol' kernel-based latency test is up and running again, along with a new timer-only benchmark. This code exploits the I-pipe's new latency tracer for x86 [Jan]. And a slew of fixes and cleanups all over the map. See the ChangeLog for details as usual. As a sidenote, now that all archs have a reliable and complete I-pipe support, the oldgen Adeos patches have been deprecated, and support for them has been dropped from the codebase. Next step is -rc3, hopefully the last one before final, scheduled for the first week of February, which de facto postpones v2.1 final for a couple of weeks or so. I'm going off-line from now to the end of January. Gilles will take the reins during that period.
