Revision 84a21dbdef0b96d773599c33c2afbb002198d303 authored by Suravee Suthikulpanit on 26 June 2017, 09:28:04 UTC, committed by Joerg Roedel on 28 June 2017, 12:44:56 UTC
Pass-through devices to VM guest can get updated IRQ affinity
information via irq_set_affinity() when not running in guest mode.
Currently, AMD IOMMU driver in GA mode ignores the updated information
if the pass-through device is setup to use vAPIC regardless of guest_mode.
This could cause invalid interrupt remapping.

Also, the guest_mode bit should be set and cleared only when
SVM updates posted-interrupt interrupt remapping information.
