Hello, I finally found back the message from Liming on the v4: https://edk2.groups.io/g/devel/message/91800
There has been some changes to the patches affecting the MdePkg, but it should not be significant changes: - Renamed FID_TRNG_* macros to ARM_SMC_ID_TRNG_*. - Added RISCV64 to the list of VALID_ARCHITECTURES for BaseTrngLibNull - Dropped patch: 'MdePkg/BaseRngLib: Rename ArmReadIdIsar0() to ArmGetFeatRng()' - Removed references in Trnglib.h to 'Special Publication' 800-90A and 800-90C, and only reference 'Arm True Random Number Generator Firmware, Interface 1.0' in the Arm implementation of the TrngLib. Liming's Rb is not currently added to the MdePkg patches. Regards, Pierre On 10/18/22 15:20, PierreGondois via groups.io wrote:
From: Pierre Gondois <pierre.gond...@arm.com> Bugzilla: Bug 3668 (https://bugzilla.tianocore.org/show_bug.cgi?id=3668) The Arm True Random Number Generator Firmware, Interface 1.0, specification defines an interface between an Operating System (OS) executing at EL1 and Firmware (FW) exposing a conditioned entropy source that is provided by a TRNG back end. This patch-set: - defines a TRNG library class that provides an interface to access the entropy source on a platform. - implements a TRNG library instance that uses the Arm FW-TRNG interface. - Adds RawAlgorithm support to RngDxe for Arm architecture using the Arm FW-TRNG interface. - Enables RNG support using FW-TRNG interface for Kvmtool Guest/Virtual firmware. This patch-set is based on the v2 from Sami Mujawar: [PATCH v2 0/8] Add Raw algorithm support using Arm FW-TRNG interface v2: https://edk2.groups.io/g/devel/message/83775 v3: https://edk2.groups.io/g/devel/message/90845 https://github.com/PierreARM/edk2/tree/Arm_Trng_v3 v4: https://github.com/PierreARM/edk2/tree/Arm_Trng_v4 v5: https://github.com/PierreARM/edk2/tree/Arm_Trng_v5 v6: https://github.com/PierreARM/edk2/tree/Arm_Trng_v6 v7: https://github.com/PierreARM/edk2/tree/Arm_Trng_v7 v8: https://github.com/PierreARM/edk2/tree/Arm_Trng_v8 v8: - Added Reviewed-by/Acked-by from Leif on ArmPkg/SecurityPkg patches. [Leif] - Renamed FID_TRNG_* macros to ARM_SMC_ID_TRNG_*. [Leif] v7: - Removed Reviewed-by from Leif. - Remove Sami's Signed-off. V6: - Added my signed-off on patches authored by Sami. [Leif] - New patch to make it easier to add new libraries in alphabetical order: ArmPkg: Sort HVC/SMC section alphbetically in ArmPkg.dsc [Leif] - Renmaed ArmHvcNullLib to ArmHvcLibNull. [Leif] - Added RISCV64 to the list of VALID_ARCHITECTURES for BaseTrngLibNull. [Leif] - Removed unnecessary space in function parameter documentation ('[in, out]'). [Rebecca] - Updated INF_VERSION to latest spec (1.29) for new libraries. [Rebecca] - Dropped the following patches [Leif]: - ArmPkg/ArmLib: Add ArmHasRngExt() - ArmPkg/ArmLib: Add ArmReadIdIsar0() helper - MdePkg/BaseRngLib: Rename ArmReadIdIsar0() to ArmGetFeatRng() V5: - Removed references in Trnglib.h to 'Special Publication' 800-90A and 800-90C, and only reference 'Arm True Random Number Generator Firmware, Interface 1.0' in the Arm implementation of the TrngLib. [Jiewen] V4: - Removed dependencies on ArmPkg and dropped patch: [PATCH v3 12/22] SecurityPkg: Update Securitypkg.ci.yaml [Jiewen] - Use a dynamically allocated array to hold available algorithms. The array is freed in a new UNLOAD_IMAGE function and allocated in arch specific implementations of GetAvailableAlgorithms(), available in AArch64/AArch64Algo.c and Arm/ArmAlgo.c. - Correctly reference gEfiRngAlgorithmSp80090Ctr256Guid Guid by copying its address (add missing '&'). [Jiewen] V3: - Address Leif's comment (moving definitions, optimizations, ...) - Add ArmMonitorLib to choose Hvc/Smc conduit depending on a Pcd. - Re-factor some parts of SecurityPkg/RngDxe/ to ease the addition of new algorithms. - Add ArmHasRngExt() function to check Arm's FEAT_RNG extension. V2: - Updates TrngLib definitions to use RETURN_STATUS as the return type from the interface functions as TrngLib is base type library. - Drops the patch "MdePkg: Add definition for NULL GUID" as there is already an equivalent definition provided by gZeroGuid. Thus, the use of gNullGuid has been replaced with gZeroGuid.
