Revision 0bbe4ced53e36786eafc2ecbf9a1761f55b4a82e authored by Adrian Huang on 26 September 2020, 10:26:02 UTC, committed by Joerg Roedel on 01 October 2020, 12:11:36 UTC
Commit 387caf0b759a ("iommu/amd: Treat per-device exclusion
ranges as r/w unity-mapped regions") accidentally overwrites
the 'flags' field in IVMD (struct ivmd_header) when the I/O
virtualization memory definition is associated with the
exclusion range entry. This leads to the corrupted IVMD table
(incorrect checksum). The kdump kernel reports the invalid checksum:
ACPI BIOS Warning (bug): Incorrect checksum in table [IVRS] - 0x5C, should be 0x60 (20200717/tbprint-177)
AMD-Vi: [Firmware Bug]: IVRS invalid checksum
Fix the above-mentioned issue by modifying the 'struct unity_map_entry'
member instead of the IVMD header.
Cleanup: The *exclusion_range* functions are not used anymore, so
get rid of them.
