Joerg, Here is an dditional tags for this series:
Fixes: 8bda0cfbdc1a ("iommu/amd: Detect and initialize guest vAPIC log") Are there any concerns with this series? Thanks Suravee On 8/20/2021 3:29 PM, Suravee Suthikulpanit wrote:
This bug is triggered when rebooting VM on a system which SVM AVIC is enabled but IOMMU AVIC is disabled in the BIOS. The series reworks interrupt remapping intialiation to check for IOMMU AVIC support (GAMSup) at earlier stage using EFR provided by IVRS table instead of the PCI MMIO register, which is available after PCI support for IOMMU is initialized. This helps avoid having to disable and clean up the already initialized interrupt-remapping-related parameter.
