Upcoming Intel Xe driver will need to have a more fine-grained control over DRM managed actions - namely, the ability to release a given action, triggering it manually at a different point in time than the final drm_dev_put(). This series adds a drmm_release_action function (which is similar to devres devm_release_action) and a simple test that uses it. v1 -> v2: - Split the test changes (Maxime) - Simplify priv lifetime management (Maxime) v2 -> v3: - Order tests alphabetically (Maxime) - Add comments explaining the intention behind the tests and the reason why DRM device can't be embedded inside test priv (Maxime) - Bring back priv lifetime management from v1 to avoid use-after-free v3 -> v4: - Split test changes into smaller patches (Maxime) - Remove the waitqueue usage in tests - Rename the test suite to match other DRM tests Michał Winiarski (6): drm/managed: Add drmm_release_action drm/tests: managed: Rename the suite name to match other DRM tests drm/tests: managed: Remove the waitqueue usage drm/tests: managed: Add comments and expect fail messages drm/tests: managed: Extract device initialization into test init drm/tests: managed: Add a simple test for drmm_managed_release drivers/gpu/drm/drm_managed.c | 39 +++++++++++ drivers/gpu/drm/tests/drm_managed_test.c | 84 +++++++++++++++++------- include/drm/drm_managed.h | 4 ++ 3 files changed, 105 insertions(+), 22 deletions(-) -- 2.43.0
