EmbeddedPkg, OvmfPkg: Produce FV3 HOBs for Extracted FVs

2026-06-13T09:06:33+00:00

EmbeddedPkg's PrePiLib and OvmfPkg's PeilessStartupLib (which uses PrePiLib) only produce FV2 HOBs for extracted FVs. However, FV3 HOBs have superceded FV2 HOBs for describing extracted FVs. This commit updates both of these libs to also produce FV3 HOBs, following PEI's pattern of producing an FV, FV2, and FV3 HOB for each extracted FV. Eventually, only FV3 HOBs will be produced, so this paves the way for that. Continuous-integration-options: PatchCheck.ignore-multi-package Signed-off-by: Oliver Smith-Denny

EmbeddedPkg, OvmfPkg: PrePiLib: Use Correct FvName in FV2 HOB Production

2026-06-13T09:06:33+00:00

PrePiLib is incorrectly producing FV2 HOBs. The FvName field of the FV2 HOB is intended to be the parent FV's name. This way the HOB consumer phase can identify when an FV has already been extracted: if the file name of the extracted FV and the parent FV name match in the FV2 HOB. With the incorrect FvName, DXE will re-extract the already extracted FV, which can be a large performance hit (some platforms we have seen ~1 second). This requires an update to FfsProcessFvFile to pass the parent FV handle through so the FV2 HOB can be correctly produced. OvmfPkg consumers are also updated.

EmbeddedPkg: Rename FfsFindSectionData as FfsFindSectionDataWithHook

2023-01-19T08:35:59+00:00

Commit c673216f53 introduces FFS_CHECK_SECTION_HOOK and add it as the second input parameter in FfsFindSectionData. This change breaks the build of ArmVirtPkg. To fix this issue, the new version of FfsFindSectionData is renamed as FfsFindSectionDataWithHook in this patch. In the following patch the original FfsFindSectionData will be added back. FfsFindSectionData is renamed as FfsFindSectionDataWithHook. Accordingly PeilessStartupLib in OvmfPkg should be updated as well. To prevent the build from being broken, the changes in OvmfPkg are in this patch. Signed-off-by: Min Xu Reviewed-by: Jiewen Yao Acked-by: Gerd Hoffmann

EmbeddedPkg/PrePiLib: Add FFS_CHECK_SECTION_HOOK when finding section

2023-01-18T03:04:27+00:00

BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=4152 EmbeddedPkg/PrePiLib provides the service of finding sections based on the input SectionType. But sometimes there maybe multiple sections with the same SectionType. FFS_CHECK_SECTION_HOOK is a hook which can be called to do additional check.

EmbeddedPkg/PrePiLib: allocate code pages for DxeCore

2017-03-14T20:08:31+00:00

The recently introduced memory protection features inadvertently broke the boot on all PrePi platforms, because the changes to explicitly use EfiBootServicesCode for loading the DxeCore PE/COFF image need to be applied in a different way for PrePi. So add a simple helper function that sets the type of an allocation to EfiBootServicesCode, and invoke it to allocate the space for DxeCore.
