Subject: [RFC PATCH 0/5] Start aligning perf test with kunit style
Perf test uses its own structs and code layout that differs from kunit
that was more recently introduced to the kernel. Besides consistency,
it is hoped that moving in the direction of kunit style will enable
reuse of infrastructure like test output formatting for continuous
testing systems. For example:
https://lore.kernel.org/linux-kselftest/CA+GJov6tdjvY9x12JsJT14qn6c7NViJxqaJk+r-K1YJzPggFDQ@mail.gmail.com/
The motivation for this restructuring comes from wanting to be able to
tag tests with a size:
https://lore.kernel.org/linux-perf-users/CAP-5=fWmGyuqFKc-EMP3rbmTkjZ3MS+YSajGZfeRMc38HS82gw@mail.gmail.com/
To have more exhaustive and slower running tests. This isn't
something kunit currently supports, nor is the execution of python and
shell tests, but it seems sensible to work on an approach with kunit
rather to invent a new wheel inside of perf.
These initial patches are just refactoring the main test suite
definitions to be in a more kunit style. Kunit isn't depended upon, it
is hoped that this can be done in later patches for the sake of
consistency.
v1. Built/tested on x86.
Ian Rogers (5):
perf test: Use macro for "suite" declarations
perf test: Use macro for "suite" definitions
perf test: Make each test/suite its own struct.
perf test: Move each test suite struct to its test
perf test: Rename struct test to test_suite
