This hidden option is set in the board configuration and indicates

the Zephyr release that the board configuration will be removed.

When set, any build for that board will generate a clearly visible

Enable QEMU virtual instruction counter. The virtual cpu will

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.
