So far, none of the responses has addressed my question---what do we do if the RTAI work doesn't get extended to version 3 of the Linux kernel by next year when Ubuntu 10.04LTS reaches its end of support? I might conclude we don't know. I just skimmed the RTAI mail list archives going back a year and the only message concerning upgrading to version 3 I found, which incidentally included a followup "...we LinuxCNC'ers need it for kernel 3.2..." reply from Sebastian Kuzminsky, went unanswered. I didn't find encouraging information rummaging around Adeos sites and the last 18 months of their mail-list archives either. Curiously, under http://download.gna.org/adeos/patches/v3.x/ there exist only subdirectories for arm and powerpc. What's up with x86? Did things happen in the development of version 3 of the Linux kernel that make the supposedly easy* port not so easy? Can it be that the PREEMPT_RT developments have caused people to lose interest in the micro-kernel approach? Since both RTAI and Xenomai 2 (as well, the micro-kernel branch of the promised Xenomai 3) depend on Adeos, I'd feel more comfortable to see actual development going on. I hope we're not in a cleft stick. Regards, Kent *Not my word. I saw the "easy" appellation in somewhere in the Adeos docs. Kernel-level stuff is all hard for me. ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
