crypto: Accelerated AES/GCM stitched implementation
|
expand
|
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. Danny Tsen (6): Patch 0: Update Kconfig and Makefile. Patch 1: Glue code for AES/GCM stitched implementation for Power10+ CPU(ppc64le). Patch 3: An accelerated AES/GCM stitched implementation. Patch 4: Supporting functions for AES. Patch 5: Supporting functions to ghash. Patch 6: A perl script to process PowerPC assembler. arch/powerpc/crypto/Kconfig | 11 + arch/powerpc/crypto/Makefile | 10 + arch/powerpc/crypto/aesp8-ppc.pl | 3846 ++++++++++++++++++++++++ arch/powerpc/crypto/ghashp8-ppc.pl | 370 +++ arch/powerpc/crypto/p10-aes-gcm-glue.c | 341 +++ arch/powerpc/crypto/p10_aes_gcm.S | 1519 ++++++++++ arch/powerpc/crypto/ppc-xlate.pl | 229 ++ 7 files changed, 6326 insertions(+) create mode 100644 arch/powerpc/crypto/aesp8-ppc.pl create mode 100644 arch/powerpc/crypto/ghashp8-ppc.pl create mode 100644 arch/powerpc/crypto/p10-aes-gcm-glue.c create mode 100644 arch/powerpc/crypto/p10_aes_gcm.S create mode 100644 arch/powerpc/crypto/ppc-xlate.pl
