drm: Make the connector .detect() callback optional

2016-12-01T15:05:53+00:00

Many drivers (21 to be exact) create connectors that are always connected (for instance to an LVDS or DSI panel). Instead of forcing them to implement a dummy .detect() handler, make the callback optional and consider the connector as always connected in that case.

drm: Don't force all planes to be added to the state due to zpos

2016-10-26T16:48:05+00:00

We don't want all planes to be added to the state whenever a plane with fixed zpos gets enabled/disabled. This is true especially for eg. cursor planes on i915, as we want cursor updates to go through w/o throttling. Same holds for drivers that don't support zpos at all (i915 actually falls into this category right now since we've not yet added zpos support). Allow drivers more freedom by letting them deal with zpos themselves instead of doing it in drm_atomic_helper_check_planes() unconditionally. Let's just inline the required calls into all the driver that currently depend on this. v2: Inline the stuff into the drivers instead of adding another helper, document things better (Daniel) Cc: Daniel Vetter Cc: Marek Szyprowski Cc: Benjamin Gaignard Cc: Vincent Abriou Cc: Laurent Pinchart Cc: Inki Dae Cc: Joonyoung Shim Cc: Seung-Woo Kim Cc: Kyungmin Park Cc: Lyude Cc: Maarten Lankhorst Cc: stable@vger.kernel.org Fixes: 44d1240d006c ("drm: add generic zpos property") Signed-off-by: Ville Syrjälä Reviewed-by: Sean Paul Acked-by: Benjamin Gaignard Signed-off-by: Daniel Vetter Link: http://patchwork.freedesktop.org/patch/msgid/1476111056-12734-1-git-send-email-ville.syrjala@linux.intel.com

drm: Add reference counting to drm_atomic_state

2016-10-17T06:19:57+00:00

drm_atomic_state has a complicated single owner model that tracks the single reference from allocation through to destruction on another thread - or perhaps on a local error path. We can simplify this tracking by using reference counting (at a cost of a few more atomics). This is even more beneficial when the lifetime of the state becomes more convoluted than being passed to a single worker thread for the commit. v2: Double check !intel atomic_commit functions for missing gets v3: Update kerneldocs Signed-off-by: Chris Wilson Cc: Daniel Vetter Cc: dri-devel@lists.freedesktop.org Reviewed-by: Eric Engestrom Reviewed-by: Sean Paul Signed-off-by: Daniel Vetter Link: http://patchwork.freedesktop.org/patch/msgid/20161014121833.439-27-chris@chris-wilson.co.uk
