Date: Tue, 28 Jan 2020 18:14:41 +0530 From: Bharat Kumar Gogada <bharat.kumar.gogada@...inx.com> To: linux-pci@...r.kernel.org, linux-kernel@...r.kernel.org Cc: bhelgaas@...gle.com, rgummal@...inx.com, Bharat Kumar Gogada <bharat.kumar.gogada@...inx.com> Subject: [PATCH v4 0/2] Adding support for Versal CPM as Root Port driver. - Add 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.
