The scheduler reads an event description file containing timestamps and
parameters then schedules those events. A user defined function is
called when those events expire. It is used for precise time
simulations.

This scenario utilities file currently implements one function.
This function is the event callback registration function which walks
through all guest devices to find those of a given type then registers
their event callback.

The masked interrupt status register should be the state of the interrupt
after masking.
There should be a logical AND instead of a logical OR between the
interrupt status and the interrupt mask.

The 'sleep' parameter sets the icount_sleep mode, which is enabled by
default. To disable it, add the 'sleep=no' parameter (or 'nosleep') to the
qemu -icount option.

While qemu is running in sleep=no mode, a warning will be printed
when no timer deadline is set.
As this mode is intended for getting deterministic virtual time, if no
timer is set on the virtual clock this determinism is broken.

real-time software using this mode, one need to write some scenario
which will simulate inputs on an emulated device then record traces from
this inputs and the associated outputs from the tested software.

icount: implement a new icount_sleep mode toggleing real-time cpu
When the icount_sleep mode is disabled, the QEMU_VIRTUAL_CLOCK runs at the
maximum possible speed by warping the sleep times of the virtual cpu to the
soonest clock deadline. The virtual clock will be updated only according
the instruction counter.

sing the virtual clock
too.
This kind of changes cannot be generic as the scenario will depend
on the tested application, so modified emulators are not part of this
patch set.

icount: implement a new icount_no_rt mode without real time cpu
sleeping
icount: add rt p
In this new icount_no_rt mode, the QEMU_VIRTUAL_CLOCK runs at the
maximum possible speed by warping the sleep times of the virtual cpu to the
soonest clock deadline. The virtual clock will be updated only according

Hello,
Check the icount option, which uses the virtual cpu instrution counter
to calculate the value of QEMU_CLOCK_VIRTUAL. This is not exactly what
you want because the clock will still run when qemu is preempted by the
host but this is the closest thing you have.
