[edk2-devel] [PATCH v1 0/9] Add Raw algorithm support using Arm FW-TRNG interface

[Sami Mujawar]

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 series:
 - 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.
