Hi All,
I am working on the TRNG FW API interface and will share more details for the discussion soon.
We had some thoughts about streamlining the RngDxe implementations and would like to share some diagrams for the discussion.
My diagrams are in Visio that I can export as JPG images. However, I am open to switching to any other suggested tool.
Hi Leif,
Can you suggest on how we can collaborate to share diagrams/documents, please?
Regards,
Sami Mujawar

There is also the TRNG FW API, which is an architected SMC firmware interface:

Subject: [edk2-devel] RFC: Adding support for ARM (RNDR etc.) to RngDxe
Currently, RngDxe in SecurityPkg only supports Intel, with RdRand support.
This RFC is to start a discussion about adding support for ARM.
I have a Git branch with support for the optional ARMv8.5 RNDR
instruction at https://github.com/bcran/edk2/commits/bcran-rndr which
moves the existing Intel support into a Rand directory, and adds code to
support RNDR in a new AArch64 directory.
There are other RNG implementations available for ARM, including
platform-specific approaches on Graviton
(https://lwn.net/Articles/790304/) and other platforms, so a more
thorough rearchitecting/redesign may be desired.
