Subject: [PATCH v9 0/2] Adding support for Versal CPM as Root Port driver
Date: Tue, 16 Jun 2020 18:26:52 +0530 [thread overview]
Message-ID: <1592312214-9347-1-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 v9:
- Removed interrupt enablement outside irqchip flow as suggested
by Marc.
- Removed using WARN_ON in if statement.
