[Xen-devel] [PATCH RFC 0/3] hpet: add support for level triggered interrupts


This series add support for level triggered HPET interrupts, which are
mandatory according to the spec.

First patch is a change for vpt in order to execute the timer
callbacks even if the interrupt is not injected because the IRQ is
masked. Second patch implements support for level triggered interrupts
in HPET and finally patch 3 is for XTF in order to add a basic HPET
functionality test.

The whole series is RFC because I've mainly tested it using the XTF
test provided in patch 3. Also it slightly changes (fixes) the
behavior of other timers because callbacks are now always executed.

Thanks, Roger.
