Merge tag 'topic/atomic-core-2015-01-05' of git://anongit.freedesktop.org/drm-intel into drm-next
Next batch of atomic work. Most important is the propertification from Rob and the nth iteration of the actual atomic ioctl originally from Ville. Big differences compared to earlier revisions: - Core properties are now fully handled by the core, drivers can only handle driver-specific properties. - Atomic props&ioctl are opt-in per file_priv, userspace needs to explicitly ask for it (like universal plane support). - For now all hidden behind the atomic module option until this has settled a bit. - Atomic modesets are currently not possible since the exact abi for how to handle the mode property is still under discussion. Besides this some cleanup patches from me and the addition of per-object state to global state backpointers to simplify drivers. * tag 'topic/atomic-core-2015-01-05' of git://anongit.freedesktop.org/drm-intel: drm: Ensure universal_planes is set for atomic drm/atomic: Hide drm.ko internal interfaces drm: Atomic modeset ioctl drm/atomic: atomic connector properties drm/atomic: atomic plane properties drm: small property creation cleanup drm/atomic: atomic_check functions drm: add atomic properties drm: refactor getproperties/getconnector drm: tweak getconnector locking drm: add atomic_get_property drm: add atomic_set_property wrappers drm: get rid of direct property value access drm: store property instead of id in obj attachment drm: allow property validation for refcnted props drm/atomic: Introduce state->obj backpointers drm/atomic-helper: Again check modeset *before* plane states drm/atomic-helper: Export both plane and modeset check helpers
