           Summary: i8254 emulation lacks proper support for s/w strobe
                    (mode 4)
           Product: Xen
           Version: unspecified
          Platform: x86
        OS/Version: other
            Status: NEW
          Severity: critical
          Priority: P2
         Component: HVM
        AssignedTo: xen-bugs@xxxxxxxxxxxxxxxxxxx
        ReportedBy: joerg@xxxxxxxxxxxxxxxxxxxxx


When attempting to run DragonFly under the HVM, the interrupt rate of the i8254
is much too low. Looking at the HVM part of the i8254, it doesn't seem to
create a timer for mode 4, which in turn means that interrupts are very
seldomly triggered.
Image for testing available on request.
