RE: [Xen-devel] can we disable fast system calls?
Aren’t fast system calls more of a
feature of the OS than xen? If your OS’s system call library uses int 80h
instead of sysenter then I guess you’ll go to that IDT vector directly. This
is an HVM that you’re looking to do this? Please update me in case I didn’t
get this correctly.
Bhaskar.

Subject: [Xen-devel] can we
disable fast system calls?
I want to modify xen 3.3.0 so that control transfers to xen after
system calls. How can I disable fast system call handlers, so that int 0x80h
functions just like all other interrupts.
Is there any older version of xen which does not have fast system calls?
Please help.
