This means that rather than provide our own implementations of .update_plane() and .disable_plane(), we expose the lower-level check/prepare/commit/cleanup entrypoints and let the DRM core implement update/disable for us using those entrypoints. The other main change that falls out of this patch is that our drm_plane's will now always have a valid plane->state that contains the relevant plane state (initial state is allocated at plane creation). The base drm_plane_state pointed to holds the requested source/dest coordinates, and the subclassed intel_plane_state holds the adjusted values that our driver actually uses. v2: - Renamed file from intel_atomic.c to intel_atomic_plane.c (Daniel) - Fix a copy/paste comment mistake (Bob) v3: - Use prepare/cleanup functions that we've already factored out - Use newly refactored pre_commit/commit/post_commit to avoid sleeping during vblank evasion v4: - Rebase to latest di-nightly requires adding an 'old_state' parameter to atomic_update; v5: - Must have botched a rebase somewhere and lost some work. Restore state 'dirty' flag to let begin/end code know which planes to run the pre_commit/post_commit hooks for. This would have actually shown up as broken in the next commit rather than this one. v6: - Squash kerneldoc patch into this one. - Previous patches have now already taken care of most of the infrastructure that used to be in this patch. All we're adding here now is some thin wrappers. v7: - Check return of intel_plane_duplicate_state() for allocation failures. v8: - Drop unused drm_plane_state -> intel_plane_state cast. (Ander) - Squash in actual transition to plane helpers. Significant refactoring earlier in the patchset has made the combined prep+transition much easier to swallow than it was in earlier iterations. (Ander) v9: - s/track_fbs/disabled_planes/ in the atomic crtc flags. The only fb's we need to update frontbuffer tracking for are those on a plane about to be disabled (since the atomic helpers never call prepare_fb() when disabling a plane), so the new name more accurately describes what we're actually tracking.
