interface

Thanks for the update.

For SecurityPkg (11~18), Acked-by: Jiewen Yao <Jiewen.yao@...>
Since the update is for AARCH64, I recommend to have an ARM people to give
Reviewed-by.

Thank you
Yao Jiewen

Subject: [PATCH v9 00/19] Add Raw algorithm support using Arm TRNG
interface

From: Pierre Gondois <pierre.gondois@...>

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 an Arm TRNG library class that provides an interface to access
the entropy source on a platform.
- implements an Arm TRNG library instance that uses the Arm FW-TRNG
interface.
- Adds RawAlgorithm support to RngDxe for Arm architecture using the Arm
TRNG interface.
- Enables RNG support using Arm 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
v9:
https://github.com/PierreARM/edk2/tree/Arm_Trng_v9

v9:
- Added BaseArmTrngLibNull as default in MdePkg/MdeLibs.dsc.inc.

[Liming]

- Renamed TrngLib to ArmTrngLib and updated documentation, commit
messages, function names accordingly. [Jiewen, Leif]
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.

ArmPkg/ArmMonitorLib: Definition for ArmMonitorLib library class
ArmPkg/ArmMonitorLib: Add ArmMonitorLib
