[PATCH v3 0/6] crypto: Accelerated AES/GCM stitched implementation

From: Danny Tsen
Date: Fri Feb 17 2023 - 11:18:33 EST


This patch series enable an accelerated AES/GCM stitched implementation for
Power10+ CPU(ppc64le). This module supports AEAD algorithm. The stitched
implementation provides 3.5X+ better performance than the baseline.

This patch has been tested with the kernel crypto module tcrypt.ko and has
passed the selftest. The patch is also tested with
CONFIG_CRYPTO_MANAGER_EXTRA_TESTS enabled.

Danny Tsen (6):
Update Kconfig and Makefile.
Glue code for AES/GCM stitched implementation.
An accelerated AES/GCM stitched implementation.
Supporting functions for AES.
Supporting functions for ghash.
A perl script to process PowerPC assembler source.
