- Adding support for versal CPM as Root port. - The Versal ACAP devices include CCIX-PCIe Module (CPM). The integrated block for CPM along with the integrated bridge can function as PCIe Root Port. - Versal CPM uses GICv3 ITS feature for assigning MSI/MSI-X vectors and handling MSI/MSI-X interrupts. - Bridge error and legacy interrupts in versal CPM are handled using versal CPM specific MISC interrupt line.
