Re: [Xen-devel] set_fast_trap() in xenlinux 
| Thanx a lot for the answer. I am trying to use xen for a system where I need the control to be transferred to xen i.e. I need to perform some checks in xen before transferring control to the guest.
 Can you please tell me how this can be done??...I think I need to disable fast handlers...How can I do this?...or should I switch to an older version of xen?  On Thu, Oct 9, 2008 at 5:14 PM, Keir Fraser <keir.fraser@xxxxxxxxxxxxx>  wrote:
 
Normal trap handlers registered on vector 0x80 are automatically 'faster'. set_fast_trap() disappeared ages ago.

 Can anyone please tell me whether HYPERVISOR_set_fast_trap() is used in linux-2.6.18.hg which runs as dom0 on xen?I searched through the code but could not find it there...
 Are fast handlers used as default?...
 
 Also, I found "fastcall" written in the prototype of many functions...does it have any relation with fastcalls??
