[v2] kselftest/arm64: fp-ptrace enhancements

[PATCH v2 0/3] kselftest/arm64: fp-ptrace enhancements

Posted by Mark Brown 1 week, 3 days ago

This series contains a bit of a grab bag of improvements to the floating
point tests, mainly fp-ptrace.  Globally over all the tests we start
using defines from the generated sysregs (following the example of the
KVM selftests) for SVCR, stop being quite so wasteful with registers
when calling into the assembler code then expand the coverage of both ZA
writes and FPMR (which was not there since fp-ptrace and the 2023 dpISA
extensions were on the list at the same time).

Changes in v2:
- Drop attempt to reference sysreg-defs.h due to build issues, just
  import the defines directly into fp-ptrace.  We can revisit later.
- Link to v1: https://lore.kernel.org/r/20241107-arm64-fp-ptrace-fpmr-v1-0-3e5e0b6e3be9@kernel.org
