[PATCH v4 0/6] crypto: Accelerated AES/GCM stitched implementation
From: Danny Tsen
Date: Mon Feb 20 2023 - 15:42:44 EST
This patch series enable an accelerated AES/GCM stitched implementation
for Power10 or later 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.
