CONFIG_QEMU_ICOUNT¶

QEMU icount mode

Type: bool

Help¶

Enable QEMU virtual instruction counter. The virtual cpu will
execute one instruction every 2^N ns of virtual time. This will
give deterministic execution times from the guest point of view.

Direct dependencies¶

BOARD_QEMU_X86 || BOARD_QEMU_X86_LAKEMONT || BOARD_QEMU_X86_TINY || QEMU_TARGET

(Includes any dependencies from ifs and menus.)
