This was originally part of my vector crypto series, but was part of a separate openssl merge request implementing GCM ghash as using non-vector extensions. As that pull-request https://github.com/openssl/openssl/pull/20078 got merged recently into openssl, we could also check if this could go into the kernel as well and provide a base for further accelerated cryptographic support. Changes in v4: - rebase on top of riscv/for-next - split out the scalar crypto implementation from the vector series - refresh code from openSSL to match exactly - Remove RFC label, as Zbc and Zbkb are ratified and the cryptographic code was merged into openSSL changes in v3: - rebase on top of 6.3-rc2 - rebase on top of vector-v14 patchset - add the missing Co-developed-by mentions to showcase the people that did the actual openSSL crypto code changes in v2: - rebased on 6.2 + zbb series, so don't include already applied changes anymore - refresh code picked from openssl as that side matures - more algorithms (SHA512, AES, SM3, SM4) Heiko Stuebner (4): RISC-V: add Zbc extension detection RISC-V: add Zbkb extension detection RISC-V: hook new crypto subdir into build-system RISC-V: crypto: add accelerated GCM GHASH implementation arch/riscv/Kbuild | 1 + arch/riscv/Kconfig | 22 ++ arch/riscv/crypto/Kconfig | 18 ++ arch/riscv/crypto/Makefile | 18 ++ arch/riscv/crypto/ghash-riscv64-glue.c | 258 ++++++++++++++++ arch/riscv/crypto/ghash-riscv64-zbc.pl | 400 +++++++++++++++++++++++++ arch/riscv/crypto/riscv.pm | 231 ++++++++++++++ arch/riscv/include/asm/hwcap.h | 2 + arch/riscv/kernel/cpu.c | 2 + arch/riscv/kernel/cpufeature.c | 2 + crypto/Kconfig | 3 + 11 files changed, 957 insertions(+) create mode 100644 arch/riscv/crypto/Kconfig create mode 100644 arch/riscv/crypto/Makefile create mode 100644 arch/riscv/crypto/ghash-riscv64-glue.c create mode 100644 arch/riscv/crypto/ghash-riscv64-zbc.pl create mode 100644 arch/riscv/crypto/riscv.pm -- 2.39.0
