[PATCH 0/2] amd_iommu: Fixes

Posted by Sairaj Kodilkar 7 months, 1 week ago

Fix following two issues in the amd viommu
1. The guest fails to setup the device when pt_supported=on, because
   amd iommu enables the no DMA memory region even when device is using DMA
   remapping mode.
2. The guest fails to boot with xtsup=on and <= 255 vCPUs, because amd_iommu
   does not enable x2apic mode.

base commit 56c6e249b6988c1b6edc2dd34ebb0f1e570a1365 (v10.0.0-rc3)
