Subject: [PATCH 0/2] Adding support for versal CPM as Root Port driver.
Date: Fri, 20 Dec 2019 17:11:10 +0530 [thread overview]
Message-ID: <1576842072-32027-1-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 MISC interrupt line.
