Re: [Xen-devel] VM System Calls

["Swapna Shingre" <amuswaps@xxxxxxxxx>]

Hello,
I need to disable the fast system call handling in xen. 

I commented the two lines in xen/arch/x86/traps.c in do_set_trap_table()

      if(cur.vector==0x80)
          init_int80_direct_trap(curr);

Is this the only change I have to make to disable fast system calls? Because my system is working after I commented those two lines, but I am unable to understand how exactly the system calls work without these two lines. Does it go through do_general_protection fault ?

Please help.
