Then we need to deposit the information needed to do the invalidate.
Lastly, we would need to interrupt. Unfortunately, here we have a
thundering herd. There could be up to 16256 processors interrupting the
same processor. That will be a lot of work. It will need to look up the
mm (without grabbing any sleeping locks in either xpmem or the kernel)
and do the tlb invalidates.
You don't need to interrupt every time. Place your data in a queue (you
do support rmw operations, right?) and interrupt. Invalidates from
other processors will see that the queue hasn't been processed yet and
skip the interrupt.
