Help¶

Such interrupt remapping hardware is provided through Intel VT-D technology. It’s being used, currently, only for MSI/MSI-X multi-vector support. If you have such PCIe device requiring multi-vector support, you will need to enable this.

Direct dependencies¶

ACPI && X86 && 64BIT

(Includes any dependencies from ifs and menus.)

Defaults¶
