Each domain is allowed to set, reset and disable its timers; when any timer runs out the domain is killed.

Why multiple watchdogs per domain? In fact, precisely two? I would have thought one would be plenty. -- Keir On 02/06/2010 11:18, "Tim Deegan" <Tim.Deegan@citrix.com> wrote:> Each domain is allowed to set, reset and disable its timers; when any > timer runs out the domain is killed. > > Patch from Christian Limpach <Christian.Limpach@citrix.com> > Signed-off-by: Tim Deegan <Tim.Deegan@citrix.com> > >_______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

I could rework it to make it indefinitely extensible but TBH I figured two watchdog timers should be enough for anyone[tm].

In future it would be a good idea to submit interface-changing patches early, or at least reserve command numbers. If someone else had taken the SCHEDOP numbers for shutdown_code and watchdog, you''d be in a spot. -- Keir> Patch from Christian Limpach <Christian.Limpach@citrix.com> > Signed-off-by: Tim Deegan <Tim.Deegan@citrix.com> > >_______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
