2026-03-19MdeModulePkg/PeiCore: Accept MemoryDiscoveredPpi from SecCoreRay Ni1-0/+10
PeiCore assumes that it runs initially from the temporary memory and switches to physical memory after PS::InstallPeiMemory() reports the physical memory range for PEI. This change enables PeiCore to run initially from the physical memory when MemoryDiscoveredPpi is passed from SEC. Signed-off-by: Ray Ni <ray.ni@intel.com>
2026-01-30MdeModulePkg/Core: Make PPI services spec complaintKhalid Ali1-3/+15
The documentation of InstallPpi() and NotifyPpi() in both the spec and function comment indicate to return EFI_OUT_OF_RESOURCES if memory allocation fails. However, the implementation of those two services assert if memory allocation fails. This is a mismatch between what the function expected to return and what actually returns. Fix this by returning EFI_OUT_OF_RESOURCES if memory allocation fails, so the code matches the documentation and comply with the spec. It is expected service consumers(callers of these functions) to handle failures appriciately. Signed-off-by: Khalid Ali <khaliidcaliy@gmail.com>

https://codeql.github.com/codeql-query-help/cpp/cpp-comparison-with-wider-type If the narrow type (smaller range) is compared against a wide type (larger range), the narrow value may overflow before reaching the wide value. This can cause unexpected behavior, such as: Infinite loops (loop condition never becomes false). Incorrect logic (comparison results are misleading).

2020-07-28MdeModulePkg/PeiCore: Enable T-RAM evacuation in PeiCore (CVE-2019-11098)Michael Kubacki1-0/+286
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.

2018-12-19MdeModulePkg PeiCore: Remove the using of PcdPeiCoreMaxPpiSupportedStar Zeng1-165/+190
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1405 Background as below. Problem: As static configuration from the PCDs, the binary PeiCore (for example in FSP binary with dispatch mode) could not predict how many FVs, Files or PPIs for different platforms. Burden: Platform developers need configure the PCDs accordingly for different platforms. To solve the problem and remove the burden, we can update code to remove the using of PcdPeiCoreMaxFvSupported, PcdPeiCoreMaxPeimPerFv and PcdPeiCoreMaxPpiSupported by extending buffer dynamically for FV, File and PPI management. This patch removes the using of PcdPeiCoreMaxPpiSupported in PeiCore.
