[0/6] selftests: arm64: Add floating point selftests

Message

Mark Brown July 30, 2020, 6:09 p.m. UTC

This series imports a series of tests for FPSIMD and SVE originally
written by Dave Martin to the tree. 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.

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
