Subject[PATCH v8 0/2] Adding support for Versal CPM as Root Port driver
Date
- 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 interrupt line.

Changes for v8:
- Added support for handling error events and INTx interrupts
separately using nested chained irqchips.
- Added support to free allocated resources in error cases.
