Signed-off-by: Mark Brown --- Changes in v2: - Rename HWCAP3_LUT6 to HWCAP3_SVE_LUT6 and make it depend on SVE. - Rebase onto v7.1-rc3. - Link to v1: https://patch.msgid.link/20260302-arm64-dpisa-2025-v1-0-0855e7f41689@kernel.org --- Mark Brown (2): arm64/cpufeature: Define hwcaps for 2025 dpISA features kselftest/arm64: Add 2025 dpISA coverage to hwcaps Documentation/arch/arm64/elf_hwcaps.rst | 24 +++++++ arch/arm64/include/uapi/asm/hwcap.h | 8 +++ arch/arm64/kernel/cpufeature.c | 11 +++ arch/arm64/kernel/cpuinfo.c | 8 +++ tools/testing/selftests/arm64/abi/hwcap.c | 116 ++++++++++++++++++++++++++++++ 5 files changed, 167 insertions(+) --- base-commit: 5d6919055dec134de3c40167a490f33c74c12581 change-id: 20260106-arm64-dpisa-2025-d6673ae6acee Best regards, -- Mark Brown
