The 'atomic' mechanism allows for multiple properties to be updated, checked, and commited atomically. This will be the basis of atomic- modeset and nuclear-pageflip.
The basic flow is:
state = dev->atomic_begin(); for (... one or more ...) obj->set_property(obj, state, prop, value); if (dev->atomic_check(state)) dev->atomic_commit(state); dev->atomic_end(state);
The split of check and commit steps is to allow for ioctls with a test-only flag (which would skip the commit step). --- drivers/gpu/drm/Makefile | 3 +- drivers/gpu/drm/ast/ast_drv.c | 6 ++ drivers/gpu/drm/ast/ast_drv.h | 1 + drivers/gpu/drm/cirrus/cirrus_drv.c | 6 ++ drivers/gpu/drm/cirrus/cirrus_drv.h | 1 + drivers/gpu/drm/drm_atomic_helper.c | 135 ++++++++++++++++++++++++++ drivers/gpu/drm/drm_crtc.c | 141 +++++++++++++++++----------- drivers/gpu/drm/exynos/exynos_drm_crtc.c | 4 +- drivers/gpu/drm/exynos/exynos_drm_drv.c | 7 ++ drivers/gpu/drm/exynos/exynos_drm_plane.c | 4 +- drivers/gpu/drm/gma500/cdv_intel_crt.c | 4 +- drivers/gpu/drm/gma500/cdv_intel_dp.c | 4 +- drivers/gpu/drm/gma500/cdv_intel_hdmi.c | 4 +- drivers/gpu/drm/gma500/cdv_intel_lvds.c | 4 +- drivers/gpu/drm/gma500/mdfld_dsi_output.c | 4 +- drivers/gpu/drm/gma500/psb_drv.c | 7 ++ drivers/gpu/drm/gma500/psb_drv.h | 1 + drivers/gpu/drm/gma500/psb_intel_drv.h | 4 +- drivers/gpu/drm/gma500/psb_intel_lvds.c | 4 +- drivers/gpu/drm/gma500/psb_intel_sdvo.c | 4 +- drivers/gpu/drm/i915/i915_drv.c | 8 ++ drivers/gpu/drm/i915/intel_crt.c | 4 +- drivers/gpu/drm/i915/intel_dp.c | 4 +- drivers/gpu/drm/i915/intel_drv.h | 1 + drivers/gpu/drm/i915/intel_hdmi.c | 4 +- drivers/gpu/drm/i915/intel_lvds.c | 4 +- drivers/gpu/drm/i915/intel_sdvo.c | 4 +- drivers/gpu/drm/i915/intel_tv.c | 5 +- drivers/gpu/drm/mgag200/mgag200_drv.c | 7 ++ drivers/gpu/drm/mgag200/mgag200_drv.h | 1 + drivers/gpu/drm/msm/mdp4/mdp4_crtc.c | 4 +- drivers/gpu/drm/msm/mdp4/mdp4_plane.c | 4 +- drivers/gpu/drm/msm/msm_drv.c | 6 ++ drivers/gpu/drm/msm/msm_drv.h | 1 + drivers/gpu/drm/nouveau/dispnv04/overlay.c | 8 +- drivers/gpu/drm/nouveau/nouveau_connector.c | 3 +- drivers/gpu/drm/nouveau/nouveau_drm.c | 7 ++ drivers/gpu/drm/nouveau/nouveau_drm.h | 1 + drivers/gpu/drm/omapdrm/omap_crtc.c | 7 +- drivers/gpu/drm/omapdrm/omap_drv.c | 6 ++ drivers/gpu/drm/omapdrm/omap_drv.h | 5 +- drivers/gpu/drm/omapdrm/omap_plane.c | 4 +- drivers/gpu/drm/qxl/qxl_display.c | 4 +- drivers/gpu/drm/qxl/qxl_drv.c | 9 ++ drivers/gpu/drm/radeon/radeon_connectors.c | 9 +- drivers/gpu/drm/radeon/radeon_drv.c | 9 ++ drivers/gpu/drm/rcar-du/rcar_du_drv.c | 7 ++ drivers/gpu/drm/rcar-du/rcar_du_plane.c | 4 +- drivers/gpu/drm/shmobile/shmob_drm_drv.c | 7 ++ drivers/gpu/drm/tilcdc/tilcdc_drv.c | 6 ++ drivers/gpu/drm/tilcdc/tilcdc_drv.h | 1 + drivers/gpu/drm/tilcdc/tilcdc_slave.c | 3 +- drivers/gpu/drm/udl/udl_connector.c | 6 +- drivers/gpu/drm/udl/udl_drv.c | 8 ++ drivers/gpu/drm/vmwgfx/vmwgfx_drv.c | 7 ++ drivers/gpu/drm/vmwgfx/vmwgfx_drv.h | 1 + drivers/gpu/drm/vmwgfx/vmwgfx_kms.c | 4 +- drivers/gpu/drm/vmwgfx/vmwgfx_kms.h | 4 +- include/drm/drmP.h | 77 +++++++++++++++ include/drm/drm_atomic_helper.h | 100 ++++++++++++++++++++ include/drm/drm_crtc.h | 14 +-- 61 files changed, 622 insertions(+), 104 deletions(-) create mode 100644 drivers/gpu/drm/drm_atomic_helper.c create mode 100644 include/drm/drm_atomic_helper.h
