I need to trap and manage exceptions (floati= ng point for example).
I want to execute at user domain (x86-ring 3) som= ething like that

real_time_task function:
{
<set exc= eption handlers> (for example fpu_handler)

<real time c= ode (asm x86)> (this code need custom management of exceptio= ns)

<release exception handlers>
}

fpu_handle= r function
{
...
}

I need to customize some exceptio= n (fpu is the most important) inside real time.
How can I do that?
Is= it possible in the rt user domain? And what about that in the rt-ker= nel domain?

Thank you
