The Amazon's Annapurna Labs FIC (Fabric Interrupt Controller) has 32 inputs/sources. The output of this interrupt controller can be legacy-wired output or, in case embedded inside PCIe devices, msi-x message. This FIC may be cascaded into another FIC or connected directly to the main CPU Interrupt Controller (e.g. GIC). The FIC is a flexible HW unit that is embedded inside different parts of the Amazon's Annapurna Labs chips. It can be a simple level 2 interrupt controller which is then configured as a wired interrupt controller that aggregates events from different units, or, while embedded inside PCIe device, it can generate MSI-X messages based on the tables configured to that PCIe device or can be configured to generate wired interrupt.
