Subject: [PATCH v7 0/2] Adding support for Versal CPM as Root Port driver
Date: Thu, 7 May 2020 17:28:34 +0530 [thread overview]
Message-ID: <1588852716-23132-1-git-send-email-bharat.kumar.gogada@xilinx.com> (raw)
- 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 v7:
- Adding device tree documentation as schema.
- Using pci_host_probe for registering bridge.
