drm/atomic: Add for_each_{connector,crtc,plane}_in_state helper macros

2015-04-11T16:50:22+00:00

This saves some typing whenever a iteration over all the connector, crtc or plane states in the atomic state is written, which happens quite often. Cc: dri-devel@lists.freedesktop.org Signed-off-by: Ander Conselvan de Oliveira Signed-off-by: Daniel Vetter

drm/atomic: Don't try to free a NULL state

2015-03-30T14:52:09+00:00

Consistently with other free functions, handle the NULL case without oopsing. Cc: dri-devel@lists.freedesktop.org Signed-off-by: Ander Conselvan de Oliveira Signed-off-by: Daniel Vetter

drm/atomic: Clear crtcs, connectors and planes when clearing state

2015-03-30T09:39:30+00:00

Users of the atomic state assume that if the pointer to a crtc, plane or connector is not NULL in the respective object vector, than the state for that object in *_states vector also won't be NULL. That assumption was broken by drm_atomic_state_clear(), which would clear the state pointer but leave the pointer to the object still set. This fixes a NULL pointer dereference in i915 caused by the use of drm_atomic_state_clear().

drm: atomic: Allow setting CRTC active property

2015-03-23T15:22:31+00:00

Before, we would set the property, but also return -EINVAL because of a broken fallthrough. Signed-off-by: Daniel Stone Signed-off-by: Daniel Vetter

drm: atomic: Expose CRTC active property

2015-03-23T15:22:31+00:00

Active was here, and we allowed users to set it, but not to get it as well. Signed-off-by: Daniel Stone Signed-off-by: Daniel Vetter

drm: Share plane pixel format check code between legacy and atomic

2015-03-10T08:59:35+00:00

Both the legacy and atomic helpers need to check whether a plane supports a given pixel format. The code is currently duplicated, share it. Signed-off-by: Laurent Pinchart [danvet: Slightly extend the docbook.] Signed-off-by: Daniel Vetter

drm: Complete moving rotation property to core

2015-03-10T08:59:32+00:00

Commit 1da30627fc511a57c9bd23a02c97f0576379f761 "drm: Add rotation value to plane state" moved the rotation property to DRM core but only did the set property part. This does the get property part as well. Signed-off-by: Tvrtko Ursulin Cc: Matt Roper Cc: dri-devel@lists.freedesktop.org Reviewed-by: Matt Roper Signed-off-by: Daniel Vetter

drm: Add DRM_DEBUG_ATOMIC

2015-02-23T10:19:49+00:00

Atomic state handling adds a lot of indirection and complexity between simple updates and drivers. For easier debugging the diagnostic output is therefore rather chatty. Which is great for tracking down atomic issues, but really annoying otherwise. Add a new DRM_DEBUG_ATOMIC to be able to filter this out.
