From 163bcc2c74a22c891c1906e6e343e28a70a54978 Mon Sep 17 00:00:00 2001 From: Maarten Lankhorst Date: Mon, 4 Sep 2017 17:04:56 +0200 Subject: drm/atomic: Move drm_crtc_commit to drm_crtc_state, v4. Most code only cares about the current commit or previous commit. Fortuantely we already have a place to track those. Move it to drm_crtc_state where it belongs. :) The per-crtc commit_list is kept for places where we have to look deeper than the current or previous commit for checking whether to stall on unpin. This is used in drm_atomic_helper_setup_commit and intel_has_pending_fb_unpin. Changes since v1: - Update kerneldoc for drm_crtc.commit_list. (danvet) Changes since v2: - Remove drm_atomic_helper_async_check hunk. (pinchartl) Changes since v3: - Fix use-after-free in drm_atomic_helper_commit_cleanup_done().

Currently we neatly track the crtc state, but forget to look at plane/connector state. When doing a nonblocking modeset, immediately followed by a setprop before the modeset completes, the setprop will see the modesets new state as the old state and free it. This has to be solved by waiting for hw_done on the connector, even if it's not assigned to a crtc. When a connector is unbound we take the last crtc commit, and when it stays unbound we create a new fake crtc commit for that gets signaled on hw_done for all the planes/connectors. We wait for it the same way as we do for crtc's, which will make sure we never run into a use-after-free situation. Changes since v1: - Only create a single disable commit. (danvet) - Fix leak in intel_legacy_cursor_update. Changes since v2: - Make reference counting in drm_atomic_helper_setup_commit more obvious. (pinchartl) - Call cleanup_done for fake commit. (danvet) - Add comments to drm_atomic_helper_setup_commit. (danvet, pinchartl) - Add comment to drm_atomic_helper_swap_state.

This will allow new members of that union to be added in the future without changing code related to the existing vbl event type. Assignments to the crtc_id field are now done when the event is allocated, rather than when delievered. This way, delivery doesn't need to have the crtc ID available. v2: * Remove 'dev' argument from create_vblank_event It wasn't being used anyways, and if we need it in the future, we can always get it from crtc->dev. * Check for MODESETTING before looking for crtc in queue_vblank_event UMS drivers will oops if we try to get a crtc, so make sure we're modesetting before we try to find a crtc_id to fill into the event.
