This series overhauls the selftests we have for the SVE ptrace interface to make them much more comprehensive than they are currently, making the coverage of the data read and written more complete. The new coverage for setting data on all vector lengths showed the issue with using the wrong buffer size with ptrace reported and fixed by: https://lore.kernel.org/linux-arm-kernel/20210909165356.10675-1-broonie@xxxxxxxxxx/ (arm64/sve: Use correct size when reinitialising SVE state). Mark Brown (8): selftests: arm64: Use a define for the number of SVE ptrace tests to be run selftests: arm64: Don't log child creation as a test in SVE ptrace test selftests: arm64: Remove extraneous register setting code selftests: arm64: Document what the SVE ptrace test is doing selftests: arm64: Clarify output when verifying SVE register set selftests: arm64: Verify interoperation of SVE and FPSIMD register sets selftests: arm64: More comprehensively test the SVE ptrace interface selftests: arm64: Move FPSIMD in SVE ptrace test into a function tools/testing/selftests/arm64/fp/Makefile | 2 +- tools/testing/selftests/arm64/fp/TODO | 9 +- .../selftests/arm64/fp/sve-ptrace-asm.S | 33 -- tools/testing/selftests/arm64/fp/sve-ptrace.c | 460 ++++++++++++------ 4 files changed, 321 insertions(+), 183 deletions(-) delete mode 100644 tools/testing/selftests/arm64/fp/sve-ptrace-asm.S base-commit: 6880fa6c56601bb8ed59df6c30fd390cc5f6dd8f -- 2.20.1
