Use Message-Signaled Interrupts where possible. With this option

enabled, PCI(e) devices which support MSI will be configured (at
|

runtime) to use them. This is typically required for PCIe devices

|

help
|

MSI can support up to 32 different messages. This will enable the
|
|
support of such capability so each message can get a vector
|
|
assigned to it. This will require for the selected architecture
|
|
to provide the necessary logic to make it work. Disable this if

the vectors cannot be managed by the hardware or if none of the

peripheral require this.

If one or more device support MSI-X, you'll need to enable this.

If a device exposes support for both MSI-X and MSI, MSI-X will be

used and MSI disabled on that device. Enable PCIE_MSI_MULTI_VECTOR
|

if you want to support multi-vector on MSI-X as well.
