Scenario: Xenomai 2.4.5, kernel 2.6.24-7 (x86) I have successfully trapped and restored int #0 (it is not reported in the example). Now I want to trap fpu exceptions (#16) of a Xenomai user task (ring 3).
xfpu_xcpt.c -> kernel module used to intercept and manage fpu (#16) exceptions.
xfpu_user.c -> xenomai user task
The easiest way (it will not be so easy the final fpu exception manager of
course!) to do this I knows was to do an fnclex but the example doesn't work
(it hangs shortly).
I have tried *many* solutions but nothing works. I think the problem is I can't
do a simple fnclex but I can't figure how to solve the problem.
Thank you
