Hi all, this is the backport of the previously pulished FPU testing cleanup. As 3.2 stable branch still supports ipipe and ipipe allows us to use the FPU in kernel space (in user task context) we have to deal with the problem differently.
The x86 fpu test relied on getting a clean fpu state (created by fninit), but there was no guarantee that this initialization happened which was uncovered when stressing server grade hardware with stress-ng and running the xenomai testsuite in parallel. 3.1 stable is also affected. I'm currently working on an additional backport to that branch.
