Well, yes actually we did support this one in 2.4.x. I did a port to the
5121_ADS close to the end of the 2.4.x maintenance cycle late in 2008.
Time flies...
Assuming you really have to stick with linux 2.6.29, I would strongly
suggest to move to Xenomai 2.6.2.1, backporting all FPU related fixes
you may find in our repo for the interrupt pipeline to this release.
Upgrading your kernel to 2.6.36 at least would be your best technical
option though.
To sum up:
- linux 2.6.29 + fpu management fixes + Xenomai 2.6.2.1
or,
- linux >= 2.6.36[.4] + Xenomai 2.6.2.1
But you really don't want to fiddle with 2.4.x anymore.
