Subject: [RFC PATCH 0/3] PCIe Host request to reserve IOVA
Date:   Wed, 12 Dec 2018 11:16:06 +0530
Message-Id: <1544593569-8923-1-git-send-email-srinath.mannam@broadcom.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Few SOCs have limitation that their PCIe host
can't allow few inbound address ranges.
Allowed inbound address ranges are listed in
dma-ranges DT property and this address ranges
are required to do IOVA mapping.
Remaining address ranges have to be reserved in
IOVA mapping.

PCIe Host driver of those SOCs has to list all
address ranges which have to reserve their IOVA
address into PCIe host bridge resource entry list.
IOMMU framework will reserve these IOVAs while
initializing IOMMU domain.

This patch set is based on Linux-4.19-rc1.

Srinath Mannam (3):
  PCI: Add dma-resv window list
  iommu/dma: IOVA reserve for PCI host reserve address list
  PCI: iproc: Add dma reserve resources to host
