Inspired by Ard Biesheuvel's RFC patches [1] for accelerating carry-less multiply under emulation.
Changes for v3: * Update target/i386 ops_sse.h. * Apply r-b. Changes for v2: * Only accelerate clmul_64; keep generic helpers for other sizes. * Drop most of the Int128 interfaces, except for clmul_64. * Use the same acceleration format as aes-round.h. r~ [1] https://patchew.org/QEMU/20230601123332.3297404-1-a...@kernel.org/ Richard Henderson (19): crypto: Add generic 8-bit carry-less multiply routines target/arm: Use clmul_8* routines target/s390x: Use clmul_8* routines target/ppc: Use clmul_8* routines crypto: Add generic 16-bit carry-less multiply routines target/arm: Use clmul_16* routines target/s390x: Use clmul_16* routines target/ppc: Use clmul_16* routines crypto: Add generic 32-bit carry-less multiply routines target/arm: Use clmul_32* routines target/s390x: Use clmul_32* routines target/ppc: Use clmul_32* routines crypto: Add generic 64-bit carry-less multiply routine target/arm: Use clmul_64 target/i386: Use clmul_64 target/s390x: Use clmul_64 target/ppc: Use clmul_64 host/include/i386: Implement clmul.h host/include/aarch64: Implement clmul.h host/include/aarch64/host/cpuinfo.h | 1 + host/include/aarch64/host/crypto/clmul.h | 41 +++++ host/include/generic/host/crypto/clmul.h | 15 ++ host/include/i386/host/cpuinfo.h | 1 + host/include/i386/host/crypto/clmul.h | 29 ++++ host/include/x86_64/host/crypto/clmul.h | 1 + include/crypto/clmul.h | 83 ++++++++++ include/qemu/cpuid.h | 3 + target/arm/tcg/vec_internal.h | 11 -- target/i386/ops_sse.h | 40 ++--- crypto/clmul.c | 112 ++++++++++++++ target/arm/tcg/mve_helper.c | 16 +- target/arm/tcg/vec_helper.c | 102 ++----------- target/ppc/int_helper.c | 64 ++++---- target/s390x/tcg/vec_int_helper.c | 186 ++++++++++------------- util/cpuinfo-aarch64.c | 4 +- util/cpuinfo-i386.c | 1 + crypto/meson.build | 9 +- 18 files changed, 434 insertions(+), 285 deletions(-) create mode 100644 host/include/aarch64/host/crypto/clmul.h create mode 100644 host/include/generic/host/crypto/clmul.h create mode 100644 host/include/i386/host/crypto/clmul.h create mode 100644 host/include/x86_64/host/crypto/clmul.h create mode 100644 include/crypto/clmul.h create mode 100644 crypto/clmul.c -- 2.34.1
