| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In defer_request() we start with the request we just unsubmitted (that should be the active request on the gpu) and then defer all of its waiters. No waiter should be ahead of the active request, so none should be marked as active. That assert failed. Of particular note this machine was undergoing persistent GPU resets due to underlying HW issues, so that may be a clue. A request is also marked as active when it is retired, regardless of current queue status, and so this assertion failure may be a result of the queue being completed by the reset and then subsequently processed by the tasklet. We can filter out retired requests here by doing the assertion check after the is-ready check (active is a subset of being ready).

Fix this by accepting DRM_BRIDGE_ATTACH_NO_CONNECTOR in bridge attachment. Implement the drm_bridge_funcs .detect() and .get_edid() operations, and call drm_bridge_hpd_notify() to report HPD. This provides the necessary API to support disabling connector creation. In addition, the field 'conn' is removed from the mtk_hdmi struct since mtk_hdmi don't create a connector. It is replaced with a pointer 'curr_conn' that points to the current connector which can be access through the global state. This patch is inspired by a similar patch for bridge/synopsys/dw-hdmi.c: commit ec971aaa6775 ("drm: bridge: dw-hdmi: Make connector creation optional") But with the difference that in mtk-hdmi only the option of not creating a connector is supported.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The bridge operation '.enable' and the audio cb '.get_eld' access hdmi->conn. In the future we will want to support the flag DRM_BRIDGE_ATTACH_NO_CONNECTOR and then we will not have direct access to the connector. The atomic version '.atomic_enable' allows accessing the current connector from the state. This patch switches the bridge to the atomic version to prepare access to the connector in later patches.
