CONFIG_IOAPIC_MASK_RTE

Mask out RTE entries on boot

Type: bool

Help

At boot, mask all IOAPIC RTEs if they may be in an undefined state. You don’t need this if the RTEs are either all guaranteed to be masked when the OS starts up, or a previous boot stage has done some IOAPIC configuration that needs to be preserved.

Direct dependencies

IOAPIC && LOAPIC

(Includes any dependencies from ifs and menus.)
