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?? _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
Normal trap handlers registered on vector 0x80 are automatically ''faster''. set_fast_trap() disappeared ages ago. -- Keir On 9/10/08 12:05, "pallavi jk" <pallutai@gmail.com> wrote:> 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?? > > > > > _______________________________________________ > Xen-devel mailing list > Xen-devel@lists.xensource.com > http://lists.xensource.com/xen-devel_______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
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?
