CONFIG_QEMU_ICOUNT_SLEEP

QEMU icount sleep mode enable

Type: bool

Help

When the virtual CPU is sleeping, the virtual time will advance
at default speed unless this option is set. With this option set,
the virtual time will jump to the next timer deadline instantly
whenever the virtual CPU goes to sleep mode and will not advance
if no timer is enabled. This behavior gives deterministic execution
times from the guest point of view.
