I'm compiling using my own Yocto setup based on meta-xenomai from [1] below.
For some reason I couldn't compile the kernel modules because of a missing
rtdm/net.h. I noticed that there was a split in the git tree while back so I
guess that's the original culprit.
However, I was never able to figure out if I had some old Xenomai-stuff laying
around in the wrong places or if I forgot to update my sdk. Further, I was not
able to get the actual compilation environment or see the real "cc commands".
Instead of digging around further I decided to check master.
So, either Yocto kept the old kernel source or there is something else broken
in 3.0.8 compilation. I haven't been able to tell which is more likely. When I
created my own 3.0.8a release files based on master it started working again
without cleaning anything else out.
This is one example of the error:
------------------------------------------------------------------------------------------------------------------------
In file included from
.../kernel-source/drivers/xenomai/net/stack/include/rtdev.h:37:0,

------------------------------------------------------------------------------------------------------------------------
I just realized that I probably hit this bug: [2/3]. I knew I saw it somewhere,
but still couldn't fint it when I was looking yesterday.
Does anyone have a good idea on how to effectively search the mailing list ?

Sorry for being unclear. With iffy I meant that I've been seeing some reports
of issues people have had, and I was probably more wrong than right. It's kind
of hard to figure out afterwards if issues you only glanced on when they passed
the mailing list was ever fixed, only a glitch, or something serious. The
bug-reporting system seems a bit under-used =)
Anyway, I was referring to these:
- [4] In my mind it was only yesterday it was released, but time flies.
- [5] with a follow up that it was also for real hardware
- [6] perhaps only amd issue ?
- [7] kvm only issue ?
