drm: Nuke drm_atomic_helper_connector_dpms

2017-08-08T12:48:48Z

It's dead code, the core handles all this directly now. The only special case is nouveau and tda988x which used one function for both legacy modeset code and -nv50 atomic world instead of 2 vtables. But amounts to exactly the same. v2: Rebase over the panel/brideg refactorings in stm/ltdc.

drm: Nuke drm_atomic_helper_connector_set_property

2017-08-08T12:47:37Z

It's dead code, the core handles all this directly now. This also allows us to unexport drm_atomic_helper_connector_set_property. The only special case is nouveau which used one function for both pre-nv50 legacy modeset code and post-nv50 atomic world instead of 2 vtables. But amounts to exactly the same. What is rather strange here is how few drivers set this up, I suspect the earlier patch to handle properties in the core did end up fixing a pile of possible issues.

drm/atomic: implement drm_atomic_helper_commit_tail for runtime_pm users

2017-07-26T11:45:08Z

The current drm_atomic_helper_commit_tail helper works only if the CRTC is accessible, and documents an alternative implementation that is supposed to be used if that happens. That implementation is then duplicated by some drivers. Instead of documenting it, let's implement an helper that all the relevant users can use directly.

Now that all drivers check the return value, convert swap_state to __must_check. This is done separately to force build warnings if we missed a driver.

2017-07-26T11:22:40Z

We want to change swap_state to wait indefinitely, but to do this swap_state should wait interruptibly. This requires propagating the error to each driver.

drm/atomic: Make private objs proper objects

2017-07-13T16:28:43Z

Make the atomic private object stuff less special by introducing proper base classes for the object and its state. Drivers can embed these in their own appropriate objects, after which these things will work exactly like the plane/crtc/connector states during atomic operations. v2: Reorder to not depend on drm_dynarray (Daniel) Cc: Dhinakaran Pandiyan Cc: Daniel Vetter Reviewed-by: Daniel Vetter #v1 Signed-off-by: Ville Syrjälä Link: http://patchwork.freedesktop.org/patch/msgid/20170712155102.26276-3-ville.syrjala@linux.intel.com

drm/atomic: initial support for asynchronous plane update

2017-07-03T08:04:44Z

In some cases, like cursor updates, it is interesting to update the plane in an asynchronous fashion to avoid big delays. The current queued update could be still waiting for a fence to signal and thus block any subsequent update until its scan out. In cases like this if we update the cursor synchronously through the atomic API it will cause significant delays that would even be noticed by the final user. This patch creates a fast path to jump ahead the current queued state and do single planes updates without going through all atomic steps in drm_atomic_helper_commit(). We take this path for legacy cursor updates. For now only single plane updates are supported, but we plan to support multiple planes updates and async PageFlips through this interface as well in the near future. v6: - move check code to drm_atomic_helper.c (Daniel Vetter) v5: - improve comments (Eric Anholt) v4: - fix state->crtc NULL check (Archit Taneja) v3: - fix iteration on the wrong crtc state - put back code to forbid updates if there is a queued update for the same plane (Ville Syrjälä) - move size checks back to drivers (Ville Syrjälä) - move ASYNC_UPDATE flag addition to its own patch (Ville Syrjälä) v2: - allow updates even if there is a queued update for the same plane. - fixes on the documentation (Emil Velikov) - unconditionally call ->atomic_async_update (Emil Velikov) - check for ->atomic_async_update earlier (Daniel Vetter) - make ->atomic_async_check() the last step (Daniel Vetter) - add ASYNC_UPDATE flag (Eric Anholt) - update state in core after ->atomic_async_update (Eric Anholt) - update docs (Eric Anholt) Cc: Daniel Vetter Cc: Rob Clark Cc: Eric Anholt Signed-off-by: Gustavo Padovan Reviewed-by: Archit Taneja (v5) Acked-by: Eric Anholt (v5) Reviewed-by: Daniel Vetter Signed-off-by: Daniel Vetter Link: http://patchwork.freedesktop.org/patch/msgid/20170630180322.29007-2-gustavo@padovan.org
