After two months since -rc1 - which is way too long, I know - there is no point in delaying 2.5-rc2 any longer, so here it is.
http://download.gna.org/xenomai/testing/xenomai-2.5-rc2.tar.bz2 Since -rc1, we mainly focused on solving multiple interrupt pipeline issues for x86, introducing optimizations in core arithmetic helpers, and eventually adding new supported platforms to the powerpc port. And as usual, fixes are all over the map. x86-wise(32/64), if you happen to run any I-pipe release in SMP mode, prior to Linux 18.104.22.168, and/or earlier than 2.2-07, you should definitely upgrade to a more recent version. Really. Regarding powerpc, we now officially support powerpc32/SMP, in addition to powerpc64/SMP we have been supporting for quite some time now. The first powerpc32/SMP platform Xenomai officially supports is Emerson's MVME7100, which is based on a dual core MPC8641D. There are things brewing in the ARM world, particularly an omap3 port, but this is not ready for prime time yet (ETA is -rc3). Stay tuned. Finally, Blackfin users may want to know that we will be tracking Mike Frysinger's tree from now on: git://git.kernel.org/pub/scm/linux/kernel/git/vapier/blackfin.git. On this architecture, the I-pipe bits should be on their way to 2.6.31 mainline already, so Blackfin is actually ahead of everyone else with respect to kernel support. Official support available with -rc2 is still based on 22.214.171.124 though, from the Blackfin project SVN/GIT mirror (see ksrc/arch/blackfin/patches/README for more). Btw, more information regarding which hardware Xenomai supports is available from: http://www.xenomai.org/index.php/Embedded_Device_Support http://www.xenomai.org/index.php/Other_Hardware_Support Oh, last point: 2.5-rc2 has a decent stability record among Xenomai maintainers, but as usual, let me emphasize the obvious: at the end of the day, only _you_ can make sure the upcoming 2.5 will work for you, and unless you feel insanely lucky these days or simply don't care about upgrading, you should not wait for 2.5.0 to perform that check.
