We have errata(Manual Errata 7024) for job "Verify IOMMU presence and configuration" when running ws2016, I'm not sure if it can be used for ws2019. If not, could you also apply a manual errata for it? HCK log please refer to the attachment Created attachment 1513611 [details]
hlk_logs
Here is msft document about this job:
This test does the following validation:
Ensures that at least one IOMMU device is present on the system
Performs basic validation of the IOMMU ACPI tables (DMAR/IVRS) looking for simple inconsistencies and/or divergence from the IOMMU specs
Performs basic validation to ensure that there are no inconsistencies in how IOMMUs are reported in the MADT table vs. in the DMAR/IVRS tables

new_params
test with new params as peter told:
-device intel-iommu,intremap=on,x-aw-bits=48,caching-mode=off,eim=on \
The former subtest is passed. But it failed as
" IOMMU[0] - DWD (DMA write draining) not supported"
and "IOMMU[0] - DWD (DMA read draining) not supported"
Test log refer to attachment "new_params"
Thanks

iommu_amd_log
AMD iommu failed logs for ws2019(hlk1809)
We can use manual errata to pass the test.

Hello Yan,
Please reference manual errata # 10745 in your submission readme file for the errors in "Verify IOMMU presence and configuration".
Thanks!
