Break the mutable state of a plane out into a separate structure and use atomic properties mechanism to set plane attributes. This makes it easier to have some helpers for plane->set_property() and for checking for invalid params. The idea is that individual drivers can wrap the state struct in their own struct which adds driver specific parameters, for easy build-up of state across multiple set_property() calls and for easy atomic commit or roll- back.
The same should be done for CRTC, encoder, and connector, but this patch only includes the first part (plane). --- drivers/gpu/drm/drm_atomic_helper.c | 137 +++++++++- drivers/gpu/drm/drm_crtc.c | 399 +++++++++++++++++++--------- drivers/gpu/drm/drm_fb_helper.c | 17 +- drivers/gpu/drm/exynos/exynos_drm_crtc.c | 4 +- drivers/gpu/drm/exynos/exynos_drm_encoder.c | 6 +- drivers/gpu/drm/exynos/exynos_drm_plane.c | 13 +- drivers/gpu/drm/i915/intel_sprite.c | 21 +- drivers/gpu/drm/msm/mdp4/mdp4_crtc.c | 2 +- drivers/gpu/drm/msm/mdp4/mdp4_plane.c | 18 +- drivers/gpu/drm/omapdrm/omap_crtc.c | 4 +- drivers/gpu/drm/omapdrm/omap_drv.c | 2 +- drivers/gpu/drm/omapdrm/omap_plane.c | 30 ++- drivers/gpu/drm/rcar-du/rcar_du_plane.c | 5 +- drivers/gpu/drm/shmobile/shmob_drm_crtc.c | 2 +- drivers/gpu/drm/shmobile/shmob_drm_plane.c | 6 +- include/drm/drm_atomic_helper.h | 37 ++- include/drm/drm_crtc.h | 88 +++++- 17 files changed, 607 insertions(+), 184 deletions(-)
