MdeModulePkg/DxeCapsuleLibFmp:Added PCD for EmbeddedDriver Support

2025-10-14T17:45:19+00:00

Currently, there is no mechanism for platforms to enable or disable support for EmbeddedDrivers in capsule updates. This patch introduces a new PCD, PcdEmbeddedDriverSupport, allowing platforms to explicitly control whether capsules containing EmbeddedDrivers are supported. This ensures capsules with embedded drivers are rejected on platforms that do not support them. This is a breaking change.By default, PcdEmbeddedDriverSupport is set to FALSE which disables embedded driver support in capsule updates across all platforms unless explicitly enabled. Platforms must opt-in by setting the PcdEmbeddedDriverSupport to TRUE in order to enable support for capsules containing embedded drivers. Signed-off-by: Pavithra Gurulingappa

MdeModulePkg/DxeCapsuleLibFmp: Check BootService Status to Use ESRT Cache

2024-09-11T20:26:20+00:00

- In c36414b131dfd0a1ca51f10f87a18955bc110ff2 change, it was introduced the ReadyToBoot event check to prevent the boot service got called in runtime to cause the issue. - In this patch introduced the ExitBootService event to replace it. It would be better to base on the BootService status to decide the source of ESRT table. - Based on the BootService availability to decide, - Exit : Use cache ESRT table in IF-condition - Not Exit: Use boot service to locate protocol in ELSE-condition Co-authored-by: Dakota Chiang Signed-off-by: Jason1 Lin

MdeModulePkg/DxeCapsuleLibFmp: Change the Event Notify to Cache ESRT Table

2024-09-11T20:26:20+00:00

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=4831 In this patch introduced the below changes, [1] Add the event of system resource table installed callback. - Register the event in DxeRuntimeCapsuleLibConstructor () - Unregister the event in DxeRuntimeCapsuleLibDestructor () [2] Migrate the event to update the module variable to cache ESRT table from ReadyToBoot to system resource table installed. [3] Add the condition to free the pool of buffer when the "mEsrtTable" is not NULL. Co-authored-by: Dakota Chiang Signed-off-by: Jason1 Lin

MdeModulePkg/DxeCapsuleLibFmp: Fix compilation error

2024-06-19T00:53:42+00:00

The commit "MdeModulePkg/DxeCapsuleLibFmp: Fix crash if no ESRT is found" leads to a compilation error in MdeModulePkg/Library/DxeCapsuleLibFmp/DxeCapsuleLib.inf. The issue occurs because the variable mDxeCapsuleLibReadyToBootEvent which is declared as extern does not exist, while it is defined in DxeCapsuleRuntime.c, a file not included in DxeCapsuleLib.inf. This patch is to fix this by moving the variable defintion to DxeCapsuleLib.c and declare it as extern in DxeCapsuleRuntime.c. Reported-by: Gua Guo Signed-off-by: Nhi Pham

MdeModulePkg/DxeCapsuleLibFmp: Fix crash if no ESRT is found

2024-06-07T15:20:42+00:00

The ESRT table is not required in UEFI firmware. In such cases, the table may not be present in the UEFI Configuration Table. The mEsrtTable is to check if the IsNestedFmpCapsule() function is invoked at runtime to determine whether to use gEsrtManagementProtocolGuid or the ESRT table from the Configuration Table. Unfortunately, the check does not cover situations where the ESRT is not present, potentially resulting in a kernel crash. This patch is intended to fix this issue. Signed-off-by: Nhi Pham

MdeModulePkg/DxeCapsuleLibFmp: Fix crash with VirtualAddressMap omitted

2023-11-28T19:10:19+00:00

If the SetVirtualAddressMap() is not called, mIsVirtualAddrConverted is FALSE and the kernel crash occurs in IsNestedFmpCapsule() when executing gBS->LocateProtocol () in the else case. To serve the omitted SetVirtualAddressMap() call, we could just check mEsrtTable presence instead of relying on mIsVirtualAddrConverted.

MdeModulePkg: Update code to be more C11 compliant by using func

2023-04-10T14:19:57+00:00

__FUNCTION__ is a pre-standard extension that gcc and Visual C++ among others support, while __func__ was standardized in C99. Since it's more standard, replace __FUNCTION__ with __func__ throughout MdeModulePkg. Signed-off-by: Rebecca Cran Reviewed-by: Michael D Kinney Reviewed-by: Ard Biesheuvel
