I need to trap and manage exceptions (floating point for example).
I want to execute at user domain (x86-ring 3) something like that
real_time_task function:
{
<set exception handlers> (for example fpu_handler)
<real time code (asm x86)> (this code need custom management of exceptions)
<release exception handlers>
}
fpu_handler function
{
...
}
I need to customize some exception (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-kernel
domain?
Thank you
