Re: [Xen-devel] Trap Handler for NX violation.

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

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
