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.

- 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):
