CONFIG_INTEL_VTD_ICTL

Intel VT-D interrupt remapping controller

Type: bool

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

No defaults. Implicitly defaults to n.

Symbols selected by this symbol
