Xen devel - Jun 2008 - Trap Handler for NX violation.

Hi

I have a question about NX trap handling in Xen. Assume that you have set
the NX/XD bit for a PT entry. I would to know wich is the trap_handler used
by Xen when NX violation is triggered.
I''m looking for trap handlers inside entry.S file for X86_32
architecture,
but I see no "specific" procedure for that. My be a general_protection
procedure is used?

Thank you very much!

Bye

As you might expect, it¹s a type of page fault. See
xen/arch/x86/traps.c:do_page_fault().
