Questions about SMP interrupts

[antonio hernandez <invaugen@telnor.net>]

Hi,
I have several question about SMP (Dual PIII).
I know that I can use one CPU to work with a RTthread only.

But my question is, Can I use one CPU to work with a RT interrupt handle
only (no other task with this CPU) ?

Can I work with floating point in this interrupt?

Can use the inner timer of this CPU to generate the RT interrupt?

Can use external source to generate the RT interrupt in this CPU?

Thank You
Antonio Hernandez
