REF:https://bugzilla.tianocore.org/show_bug.cgi?id=1614 Introduces new changes to PeiCore to move the contents of temporary RAM visible to the PeiCore to permanent memory. This expands on pre-existing shadowing support in the PeiCore to perform the following additional actions: 1. Migrate pointers in PPIs installed in PeiCore to the permanent memory copy of PeiCore. 2. Copy all installed firmware volumes to permanent memory. 3. Relocate and fix up the PEIMs within the firmware volumes. 4. Convert all PPIs into the migrated firmware volume to the corresponding PPI address in the permanent memory location. This applies to PPIs and PEI notifications. 5. Convert all status code callbacks in the migrated firmware volume to the corresponding address in the permanent memory location. 6. Update the FV HOB to the corresponding firmware volume in permanent memory. 7. Use PcdMigrateTemporaryRamFirmwareVolumes to control if enable the feature or not. when disable the PCD, the EvacuateTempRam() will never be called. The function control flow as below: PeiCore() DumpPpiList() EvacuateTempRam() ConvertPeiCorePpiPointers() ConvertPpiPointersFv() MigratePeimsInFv() MigratePeim() PeiGetPe32Data() LoadAndRelocatePeCoffImageInPlace() MigrateSecModulesInFv() ConvertPpiPointersFv() ConvertStatusCodeCallbacks() ConvertFvHob() RemoveFvHobsInTemporaryMemory() DumpPpiList() Cc: Jian J Wang <jian.j.wang@intel.com> Cc: Hao A Wu <hao.a.wu@intel.com> Cc: Dandan Bi <dandan.bi@intel.com> Cc: Liming Gao <liming.gao@intel.com> Cc: Debkumar De <debkumar.de@intel.com> Cc: Harry Han <harry.han@intel.com> Cc: Catharine West <catharine.west@intel.com> Signed-off-by: Michael Kubacki <michael.a.kubacki@intel.com> Reviewed-by: Liming Gao <liming.gao@intel.com> Acked-by: Laszlo Ersek <lersek@redhat.com> |
