References: bsc#1135799 # Commit ef04aa69f06d38b8852d6cca02d13aaf3deaa74c # Date 2019-08-07 10:43:01 +0100 # Author Andrew Cooper <andrew.cooper3@citrix.com> # Committer Andrew Cooper <andrew.cooper3@citrix.com> passthrough/amd: Drop "IOMMU not found" message Since c/s 9fa94e10585 "x86/ACPI: also parse AMD IOMMU tables early", this function is unconditionally called in all cases where a DMAR ACPI table doesn't exist. As a consequnce, "AMD-Vi: IOMMU not found!" is printed in all cases where an IOMMU isn't present, even on non-AMD systems. Drop the message - it isn't terribly interesting anyway, and is now misleading is a number of common cases.
