To avoid hanging userspace components that might have been waiting on the active fences of the destroyed timeline we need to signal with error all remaining fences on such timeline. This restore the default behaviour of the Android sw_sync framework, which Android still relies on. It was broken on the dma fence conversion a few years ago and never fixed. v2: Do not bother with cleanup do the list (Chris Wilson) Reviewed-by:

The current error handling when devm_kzalloc fails performs a non-null check on connector which is redundant because connector is null at that failure point. Once this is removed, make the failure path into a trivial -ENOMEM return to clean up the error handling. Also remove need to initialize connector to NULL.

By always keeping track of the last commit in plane_state, we know whether there is an active update on the plane or not. With that information we can reject the fast update, and force the slowpath to be used as was originally intended. We cannot use plane_state->crtc->state here, because this only mentions the most recent commit for the crtc, but not the planes that were part of it. We specifically care about what the last commit involving this plane is, which can only be tracked with a pointer in the plane state. Changes since v1: - Clean up the whole function here, instead of partially earlier. - Add mention in the commit message why we need commit in plane_state. - Swap plane->state in intel_legacy_cursor_update, instead of reassigning all variables. With this commit We know that the cursor is not part of any active commits so this hack can be removed. Cc: Gustavo Padovan <gustavo.padovan@collabora.com> Signed-off-by:

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. (pinchartl) Signed-off-by:

When commit synchronization through drm_crtc_commit was first introduced, we tried to solve the problem of the flip_done needing a reference count by blocking in cleanup_done. This has been changed by commit 24835e44 ("drm: reference count event->completion") which made the waits here no longer needed. However, even after this commit we still needed the wait because otherwise we cannot wait for the flip_done because this item might have been removed from the list. Changed since v1: - Make mention of cleanup_done completing before flip_done. Signed-off-by:

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(). Signed-off-by:

The next commit removes the wait for flip_done in in drm_atomic_helper_commit_cleanup_done, but we need it for the tests to pass. Instead of using complicated vblank tracking which ends up being ignored anyway, call the correct atomic helper. :) Changes since v1: - Always call drm_atomic_helper_wait_for_flip_done, even for legacy cursor updates.

The header comment in include/trace/define_trace.h specifies that the TRACE_INCLUDE_PATH needs to be relative to the define_trace.h header rather than the trace file including it. Most instances get that wrong and work around it by adding the $(src) directory to the include path. While this works, it is preferable to refer to the correct path to the trace file in the first place and avoid any workaround. Acked-by:

Based on patch "Convert drivers to explicit reset API" from Philipp Zabel Commit a53e35db ("reset: Ensure drivers are explicit when requesting reset lines") started to transition the reset control request API calls to explicitly state whether the driver needs exclusive or shared reset control behavior. Convert all drivers requesting exclusive resets to the explicit API call so the temporary transition helpers can be removed. No functional changes.

This adds a new DRM driver for the Faraday Technology TVE200 block. This "TV Encoder" encodes a ITU-T BT.656 stream and can be found in the StorLink SL3516 (later Cortina Systems CS3516) as well as the Grain Media GM8180. I do not have definitive word from anyone at Faraday that this IP block is theirs, but it bears the hallmark of their 3-digit version code (200) and is used in two SoCs from completely different companies. (Grain Media was fully owned by Faraday until it was transferred to NovoTek this january, and Faraday did lots of work on the StorLink SoCs.) The D-Link DIR-685 uses this in connection with the Ilitek ILI9322 panel driver that supports BT.656 input, while the GM8180 apparently has been used with the Cirrus Logic CS4954 digital video encoder. The oldest user seems to be something called Techwall 2835. This driver is heavily inspired by Eric Anholt's PL111 driver and therefore I have mentioned all the ancestor authors in the header file.
