** Description changed: GCP is requesting the backport of the patch "6b080c4e815ceba3c08f iommu/amd: Add map/unmap_pages() iommu_domain_ops callback support" from upstream 6.2 to the 5.19 (kinetic) gcp kernel The following two patches are required for the backport: 6b080c4e815ceba3c08ffa980c858595c07e7 iommu/amd/io-pgtable: Implement map_pages io_pgtable_ops callback 251c4db699ca7b966db7e59e8663a231c96ba iommu/amd/io-pgtable: Implement unmap_pages io_pgtable_ops callback More info at https://canonical.lightning.force.com/lightning/r/Case/5008e00000CjJJCAA3/view Impact: - - This allows the AMD iommu driver to map/unmap multiple pages in one call. GCP states that this also has a security side-effect which they are interested in. + - This allows the AMD iommu driver to map/unmap multiple pages in one call. GCP states that these changes also have a security side-effect which they are interested in. Testing: - Boot-tested the changes in a gcp SEV and non-SEV environment on AMD hardware.
