I didn't get any feedback on the RFC version of this that I posted a
while back [1]. I'd still like to add the test, especially now that
6.1 has been released with this new feature, so I've rebased it onto
perf/core and double checked that it's still working.
Applies to perf/core (0c3852adae83)
Thanks

Ensure that the availability of the VG register behaves as expected
depending on the kernel version and SVE support.

The first two version numbers are used since that is where the ABI
changes happen, so seems to be the most useful for now.
'Until' is exclusive and 'since' is inclusive so that the same version
number can be used to mark a point where the change comes into effect.
This allows keeping the tests in a state where new tests will also pass
on older kernels if the existence of a new feature isn't explicitly
broadcast by the kernel. For example extended user regs are currently
discovered by trial and error calls to perf_event_open.

This can be used to skip tests or provide different test values on
different platforms. For example to run a test only where Arm SVE is
present add this to the config section:
auxv = auxv["AT_HWCAP"] & 0x200000 == 0x200000
The value is a freeform Python expression that is evaled in the context
of a map called "auxv" that contains the decoded auxiliary vector.

Currently the return value is used to skip the test, but sometimes it
can be useful to test if a certain command should return a certain exit
code.

Thanks Arnaldo. It doesn't look like rk3399 has SVE, so
test-record-user-regs-no-sve-aarch64 will run to check that the kernel
won't give you the new register. So I suppose the answer to the question
is partially.
For test-record-user-regs-sve-aarch64, I've been running it on a
Graviton 3 on AWS which has SVE:
