Hi all,
I want to perform some encryption/decryption in TF-A. I find that Arm provides some hardware-assisted instructions for encryption and integrity verification (e.g., AESE, SHA1...). But it seems that FVP does not support them.
[OD] the model requires a crypto plugin that may not be available in the public FVP version. You should contact Arm support if needing access to it.
I recently read Armv9 and know that Arm purposes SVE/SVE2 to accelerate the matrix computation. It seems that it can be another approach to accelerate the encryption.
Since I am a novice in Armv9 (and in FVP), thus, I want to ask: (1) Do FVP and TF-A support the SVE? If yes, how to configure it? (2) Do FVP and TF-A support the SVE2? If yes, how to configure it?
[OD] You need to invoke the SVE plugin on the FVP command line by: --plugin=<...>/Base_RevC_AEMvA_pkg/plugins/Linux64_GCC-9.3/ScalableVectorExtension.so

Looking forward to your reply!
