From: Michael Kubacki <michael.kubacki@microsoft.com> REF:https://bugzilla.tianocore.org/show_bug.cgi?id=3479 The UEFI variable drivers such as VariableRuntimeDxe, VariableSmm, VariableStandaloneMm, etc. (and their dependent protocol/library stack), typically acquire UEFI variable store flash information with PCDs declared in MdeModulePkg. For example: [Pcd] gEfiMdeModulePkgTokenSpaceGuid.PcdFlashNvStorageVariableBase gEfiMdeModulePkgTokenSpaceGuid.PcdFlashNvStorageVariableBase64 gEfiMdeModulePkgTokenSpaceGuid.PcdFlashNvStorageVariableSize These PCDs work as-is in the StandaloneMm driver if they are not dynamic such as Dynamic or DynamicEx because PCD services are not readily available in the Standalone MM environment. Platforms that use Standalone MM today, must define these PCDs as FixedAtBuild in their platform build. However, the PCDs do allow platforms to treat the PCDs as Dynamic/DynamicEx and being able to support that is currently a gap for Standalone MM. This patch series introduces a HOB that can be produced by the platform to provide the same information. The HOB list is available to Standalone MM. The PCD declarations are left as-is in MdeModulePkg for backward compatibility. This means unless a platform wants to use the HOB, their code will continue to work with no change (they do not need to produce the HOB). Only if the HOB is found, is its value used instead of the PCDs. Due to the large number of consumers of this information, access to the base address and size values is abstracted in a new library class (as requested in the v1 series) called VariableFlashInfoLib. The API of VariableFlashInfoLib does not bind the underlying data structure to the information returned to library users to allow flexibility in the library implementation in the future. V3 changes: 1. To better clarify usage, renamed the members "NvStorageBaseAddress" and "NvStorageLength" in "VARIABLE_FLASH_INFO" to "NvVariableBaseAddress" and "NvVariableLength". 2. Added description comments to the fields in "VARIABLE_FLASH_INFO". V2 changes: 1. Abstracted flash info data access with VariableFlashInfoLib. 2. Updated package builds in the repo that build the variable and FTW drivers to include VariableFlashInfoLib. 3. Removed a redundant variable assignment in VariableSmm.c. 4. Updated comments in FtwMisc.c and FaultTolerantWritePei.c to indicate driver assumption is UINTN (not UINT32) 5. Added a version field to the VARIABLE_FLASH_INFO structure.

Michael: Can you give the suggestion about how to install this variable flash info hob when it is required? Because VariablePei is early PEIM, how to make sure the variable flash info hob is installed before GetVariable is called? On VARIABLE_FLASH_INFO structure definition, the first field is UINT32, other fields are all UINT64. How about reserve 4 bytes after the first field? If so, all fields are at the nature alignment address.

Hi Liming, To help move reviews along, I went ahead and sent a v4 patch series with the following information: 1. More details about when the HOB is required. 2. More details about when the HOB should be installed in the boot flow. 3. A 4 byte reserved field after the "Version" field. The details are in MdeModulePkg/Include/Guid/VariableFlashInfo.h V4: https://edk2.groups.io/g/devel/message/88787 CI PR: https://github.com/tianocore/edk2/pull/2768 Regards, Michael On 4/11/2022 9:25 PM, gaoliming wrote: > Michael: > Can you give the suggestion about how to install this variable flash info > hob when it is required?
