Title:
amd_iommu possible data corruption
Status in linux package in Ubuntu:
In Progress
Status in linux source package in Bionic:
Fix Released
Status in linux source package in Cosmic:

Status in linux source package in Disco:

Bug description:
[Impact]
If a device has an exclusion range specified in the IVRS
table, this region needs to be reserved in the iova-domain
of that device. This hasn't happened until now and can cause
data corruption on data transfered with these devices.
The exlcusion range limit register needs to contain the
base-address of the last page that is part of the range, as
bits 0-11 of this register are treated as 0xfff by the
hardware for comparisons.
So correctly set the exclusion range in the hardware to the
last page which is _in_ the range.
[Fixes]
Cherry pick the following from Mainline
fd3b3448cf5adc2a2f09b70eaad03c27fe79e7a6 iommu/amd: Reserve exclusion range
in iova-domain
3c677d206210f53a4be972211066c0f1cd47fe12 iommu/amd: Set exclusion range
correctly

correctly
Note Disco only required f1cd47fe12 as the first patch was already
picked in LP: #1830934
Not necessary for Eoan as these are already upstream in 5.2-rc1
[Regression Risk]
Low,this adds memory protection to the driver and has already been applied
upstream and tested by Dell for 24 hours with no failures noted.
