Subject: [PATCH v5 0/2] Adding support for Versal CPM as Root Port driver
Date: Thu, 30 Jan 2020 21:42:49 +0530 [thread overview]
Message-ID: <1580400771-12382-1-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.
