Since these extensions have some overlap in terms of register usage and must sometimes be tested together they're dropped into a single directory. I've adapted some of the tests to run within the kselftest framework but there are also some stress tests here that are intended to be run as soak tests so aren't suitable for running by default and are mostly just integrated with the build system. There doesn't seem to be a more suitable home for those stress tests and they are very useful for work on these areas of the code so it seems useful to have them somewhere in tree. v2: Rebased onto v5.9-rc1 Mark Brown (6): selftests: arm64: Test case for enumeration of SVE vector lengths selftests: arm64: Add test for the SVE ptrace interface selftests: arm64: Add stress tests for FPSMID and SVE context switching selftests: arm64: Add utility to set SVE vector lengths selftests: arm64: Add wrapper scripts for stress tests selftests: arm64: Add build and documentation for FP tests tools/testing/selftests/arm64/Makefile | 2 +- tools/testing/selftests/arm64/fp/.gitignore | 5 + tools/testing/selftests/arm64/fp/Makefile | 17 + tools/testing/selftests/arm64/fp/README | 100 +++ .../testing/selftests/arm64/fp/asm-offsets.h | 11 + tools/testing/selftests/arm64/fp/assembler.h | 57 ++ .../testing/selftests/arm64/fp/fpsimd-stress | 60 ++ .../testing/selftests/arm64/fp/fpsimd-test.S | 482 +++++++++++++ .../selftests/arm64/fp/sve-probe-vls.c | 58 ++ .../selftests/arm64/fp/sve-ptrace-asm.S | 33 + tools/testing/selftests/arm64/fp/sve-ptrace.c | 336 +++++++++ tools/testing/selftests/arm64/fp/sve-stress | 59 ++ tools/testing/selftests/arm64/fp/sve-test.S | 672 ++++++++++++++++++ tools/testing/selftests/arm64/fp/vlset.c | 155 ++++ 14 files changed, 2046 insertions(+), 1 deletion(-) create mode 100644 tools/testing/selftests/arm64/fp/.gitignore create mode 100644 tools/testing/selftests/arm64/fp/Makefile create mode 100644 tools/testing/selftests/arm64/fp/README create mode 100644 tools/testing/selftests/arm64/fp/asm-offsets.h create mode 100644 tools/testing/selftests/arm64/fp/assembler.h create mode 100755 tools/testing/selftests/arm64/fp/fpsimd-stress create mode 100644 tools/testing/selftests/arm64/fp/fpsimd-test.S create mode 100644 tools/testing/selftests/arm64/fp/sve-probe-vls.c create mode 100644 tools/testing/selftests/arm64/fp/sve-ptrace-asm.S create mode 100644 tools/testing/selftests/arm64/fp/sve-ptrace.c create mode 100755 tools/testing/selftests/arm64/fp/sve-stress create mode 100644 tools/testing/selftests/arm64/fp/sve-test.S create mode 100644 tools/testing/selftests/arm64/fp/vlset.c Acked-by: Shuah Khan Acked-by: Dave Martin
