Subject: [PATCH v13 0/3] iommu: add rmrr Xen command line option
Date: Tue, 10 Jan 2017 16:57:33 -0600	[thread overview]
Message-ID: <1484089056-8762-1-git-send-email-venu.busireddy@oracle.com> (raw)

From: Elena Ufimtseva <elena.ufimtseva@oracle.com>

Add Xen command line option rmrr to specify RMRR regions that are not
defined in ACPI thus causing IO Page Faults and prevent dom0 from booting
if "iommu=dom0-strict" option is specified on the Xen command line.
These additional regions will be added to the list of RMRR regions parsed
from ACPI.

Changes in v13:
 - Implement feedback from Kevin Tian.

   https://lists.xenproject.org/archives/html/xen-devel/2015-10/msg03170.html
   https://lists.xenproject.org/archives/html/xen-devel/2015-10/msg03171.html
 - Limit all source lines and comments to 80 characters per line.
 - Implement coding style suggestions from Konrad Wilk.
 - Changed the Author to Elena Ufimtseva <elena.ufimtseva@oracle.com>

Changes in v12:
 - Mostly cosmetic fixes from Jan's review on v11.

Changes in v11:
 - changed macro to print extra RMRR ranges and added argument macro;
 - fixed the overlapping check if condition error;
 - fixed the loop exit condition when checking pfn in RMRR region;

Elena Ufimtseva (3):
  iommu VT-d: separate rmrr addition function.
  pci: add wrapper for parse_pci.
  iommu: add rmrr Xen command line option for extra rmrrs
