From f759f5b53f1caf734bdffcb9519d4edd877b017f Mon Sep 17 00:00:00 2001 From: Maxime Ripard Date: Thu, 1 Dec 2022 16:11:48 +0100 Subject: drm/vc4: tests: Introduce a mocking infrastructure MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit In order to test the current atomic_check hooks we need to have a DRM device that has roughly the same capabilities and layout that the actual hardware. We'll also need a bunch of functions to create arbitrary atomic states. Let's create some helpers to create a device that behaves like the real one, and some helpers to maintain the atomic state we want to check.
