Hi,

because I think it is decision time, here is a my memo:

We have three choices:

* Bull vIOSAPIC patch cleaned-up [without IRQ sharing] submitted this week
 and Intel vIRQ patch submitted when ready.
 I think this is the compromise, and this allows my to work on SMP/SMP-g and 
driver domains during Intel work.

* Bull vIOSAPIC patch is withdrawn and Intel works on vIRQ. 
 I think this is the Intel solution.  This will avoid left and right turns, 
but will also suspend work on SMP-g (because of IPI).

* Bull vIOSAPIC patch cleaned-up and submitted.  Intel vIRQ patch delayed.
 This is the Bull solution. It will allow progress on SMP/SMP-g and dd, and 
will save force to continue working on new features to try to include 
Xen/ia64 in the new RH release.

Now, Intel please choose among these choices (or another choice), and I will 
accept it.

Tristan.
