Because ACRN is a flexible, lightweight reference hypervisor, we provide
limited timer management services:
- Only the lapic tsc-deadline timer is supported as the clock source.
- Only the LAPIC tsc-deadline timer is supported as the clock source.
- A timer can only be added on the logical CPU for a process or thread. Timer
scheduling or timer migrating is not supported.

When the system boots, we check that the hardware supports the LAPIC
tsc-deadline timer by checking CPUID.01H:ECX.TSC_Deadline[bit 24]. If
support is missing, we output an error message and panic the hypervisor.
If supported, we register the timer interrupt callback that raises a
timer softirq on each logical CPU and sets the lapic timer mode to
timer softirq on each logical CPU and sets the LAPIC timer mode to
tsc-deadline timer mode by writing the local APIC LVT register.
