kselftest/arm64: Don't probe the current VL for unsupported vector types

2023-12-19T10:03:17+00:00

The vec-syscfg selftest verifies that setting the VL of the currently
tested vector type does not disrupt the VL of the other vector type. To do
this it records the current vector length for each type but neglects to
guard this with a check for that vector type actually being supported. Add
one, using a helper function which we also update all the other instances
of this pattern.

kselftest/arm64: Log SVCR when the SME tests barf

2023-12-11T12:02:00+00:00

On failure we log the actual and expected value of the register we detect
a mismatch in. For SME one obvious potential source of corruption would be
if we had corrupted SVCR since changes in streaming mode will reset the
register values, log the value to aid in understanding issues.

kselftest/arm64: Improve output for skipped TPIDR2 ABI test

2023-12-11T12:00:43+00:00

When TPIDR2 is not supported the tpidr2 ABI test prints the same message
for each skipped test:

  ok 1 skipped, TPIDR2 not supported

which isn't ideal for test automation software since it tracks kselftest
results based on the string used to describe the test. This is also not
standard KTAP output, the expected format is:

  ok 1 # SKIP default_value

Updated the program to generate this, using the same set of test names that
we would run if the test actually executed.

kselftest/arm64: Fix output formatting for za-fork

2023-11-23T14:16:15+00:00

The za-fork test does not output a newline when reporting the result of
the one test it runs, causing the counts printed by kselftest to be
included in the test name.  Add the newline.
