drm/tests: helpers: Create kunit helper to destroy a drm_display_mode

2025-04-08T15:26:58+00:00

A number of test suites call functions that expect the returned drm_display_mode to be destroyed eventually. However, none of the tests called drm_mode_destroy, which results in a memory leak. Since drm_mode_destroy takes two pointers as argument, we can't use a kunit wrapper. Let's just create a helper every test suite can use.

drm/tests: Drop drm_kunit_helper_acquire_ctx_alloc()

2025-03-03T13:21:58+00:00

lockdep complains when a lock is released in a separate thread the lock is taken in, and it turns out that kunit does run its actions in a separate thread than the test ran in. This means that drm_kunit_helper_acquire_ctx_alloc() just cannot work as it's supposed to, so let's just get rid of it.

As Maxime suggested, add a new helper drm_kunit_display_mode_from_cea_vic(), it can replace the direct call of drm_display_mode_from_cea_vic(), and it will help solving the `mode` memory leaks.

drm/tests: Add helper to create mock crtc

2024-02-28T15:36:36+00:00

We're going to need a full-blown, functional, KMS device to test more components of the atomic modesetting infrastructure. Let's add a new helper to create a dumb, mocked, CRTC. By default it will create a CRTC relying only on the default helpers, but drivers are free to deviate from that.
