If OpRegion version is 2.0,\nthe OpRegion Mailbox 3 RVDA store the absolute address of\nraw VBT data from OpRegion base;\n\n2. If OpRegion version is 2.1,\nThe OpRegion Mailbox 3 RVDA store the relative address of\nraw VBT data from OpRegion base.\n\nCurrently, we only support the second case.\n\nThis patch assures the GOP driver can\nobtain the VBT correctly when OpRegion version is 2.1\n\nTracked-On: projectacrn/acrn-hypervisor#6603","shortMessageHtmlLink":"Add PlatformGopPolicy and Get VBT from OpRegion"}},{"before":null,"after":"a44634ea4fa78a9753307ca94888c87960897a91","ref":"refs/heads/gvt-d_test","pushedAt":"2023-08-31T10:51:33.000Z","pushType":"branch_creation","commitsCount":0,"pusher":{"login":"gangqizai","name":"gangqizai","path":"/gangqizai","primaryAvatarUrl":"https://avatars.githubusercontent.com/u/143635944?s=80&v=4"},"commit":{"message":"Add patch OvmfPkg-add-IgdAssignmentDxe","shortMessageHtmlLink":"Add patch OvmfPkg-add-IgdAssignmentDxe"}}],"hasNextPage":false,"hasPreviousPage":false,"activityType":"all","actor":null,"timePeriod":"all","sort":"DESC","perPage":30,"cursor":"Y3Vyc29yOnYyOpK7MjAyMy0wOC0zMVQxMTowNDowMi4wMDAwMDBazwAAAAN2iVsQ","startCursor":"Y3Vyc29yOnYyOpK7MjAyMy0wOC0zMVQxMTowNDowMi4wMDAwMDBazwAAAAN2iVsQ","endCursor":"Y3Vyc29yOnYyOpK7MjAyMy0wOC0zMVQxMDo1MTozMy4wMDAwMDBazwAAAAN2hx1p"}},"title":"Activity · gangqizai/edk2"}
