| |
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.
v2. Gets to a point of the perf test test suite/case structs being close facsimiles of the kunit ones. It also addresses feedback on the v1 RFC, in particular from Jiri Olsa <jolsa@redhat.com>.
v1. Built/tested on x86.
