| select PCIE_MSI_MULTI_VECTOR |
| 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. |
| config INTEL_VTD_ICTL_XAPIC_PASSTHROUGH |
| bool "XAPIC mode pass-through" |
| If XAPIC mode is enabled, it will avoid remapping all interrupts. |
| config INTEL_VTD_ICTL_INIT_PRIORITY |
| int "Initialization priority" |
| This device should be initialized as soon as possible, before any |
| other device that would require it for MSI/MSI-X multi-vector support. |
