The idea behind this series came from a recent discussion on IRC during which we discussed infoframes generation of i915 vs everything else. Infoframes generation code still requires some decent boilerplate, with each driver doing some variation of it. In parallel, while working on vc4, we ended up converting a lot of i915 logic (mostly around format / bpc selection, and scrambler setup) to apply on top of a driver that relies only on helpers. While currently sitting in the vc4 driver, none of that logic actually relies on any driver or hardware-specific behaviour. The only missing piece to make it shareable are a bunch of extra variables stored in a state (current bpc, format, RGB range selection, etc.). The initial implementation was relying on some generic subclass of drm_connector to address HDMI connectors, with a bunch of helpers that will take care of all the "HDMI Spec" related code. Scrambler setup is missing at the moment but can easily be plugged in. The feedback was that creating a connector subclass like was done for writeback would prevent the adoption of those helpers since it couldn't be used in all situations (like when the connector driver can implement multiple output) and required more churn to cast between the drm_connector and its subclass. The decision was thus to provide a set of helper and to store the required variables in drm_connector and drm_connector_state. This what has been implemented now. Hans Verkuil also expressed interest in implementing a mechanism in v4l2 to retrieve infoframes from HDMI receiver and implementing an infoframe-decode tool. This series thus leverages the infoframe generation code to expose it through debugfs. I also used the occasion to unit-test everything but the infoframe generation, which can come later once I get a proper understanding of what the infoframe are supposed to look like. This required to add some extra kunit helpers and infrastructure to have multiple EDIDs and allow each test to run with a particular set of capabilities. This entire series has been tested on a Pi4, passes all its unittests (125 new tests), and has only been build-tested for sunxi and rockchip.
