Hello all, This patch series is a continuation of rework of blending support in Exynos DRM driver. Some background can be found here: http://www.spinics.net/lists/dri-devel/msg96969.html Daniel Vetter suggested that zpos property should be made generic, with well-defined semantics. This patchset is my proposal for such generic zpos property: - added zpos properties to drm core and plane state structures, - added helpers for normalizing zpos properties of given set of planes, - well defined semantics: planes are sorted by zpos values and then plane id value if zpos equals. Patches are based on top of latest exynos-drm-next branch. Best regards Marek Szyprowski Samsung R&D Institute Poland Changelog: v4: - made min/max values of zpos property driver dependent (request of Ville Syrjälä) - adjusted some comments v3: http://www.spinics.net/lists/dri-devel/msg98207.html - on request of Daniel Vetter, moved all normalization process to DRM core, drivers can simply use plane_state->normalized_zpos in their atomic_check/update callbacks with no additional changes needed - updated documentation v2: http://www.spinics.net/lists/dri-devel/msg98093.html - dropped 2 fixes for Exynos DRM, which got merged in meantime - added more comments and kernel docs for core functions as suggested by Daniel Vetter - reworked initialization of zpos properties (moved assiging property class to common code), now the code in the driver is even simpler - while reworking of intialization of zpos property code, did the same change to generic rotation property v1: http://www.spinics.net/lists/dri-devel/msg97709.html - initial version Patch summary: Marek Szyprowski (3): drm: add generic zpos property drm/exynos: use generic code for managing zpos plane property drm: simplify initialization of rotation property Documentation/DocBook/gpu.tmpl | 14 ++- drivers/gpu/drm/atmel-hlcdc/atmel_hlcdc_plane.c | 10 +- drivers/gpu/drm/drm_atomic.c | 4 + drivers/gpu/drm/drm_atomic_helper.c | 118 ++++++++++++++++++++++++ drivers/gpu/drm/drm_crtc.c | 96 +++++++++++++++++-- drivers/gpu/drm/exynos/exynos_drm_drv.h | 2 - drivers/gpu/drm/exynos/exynos_drm_plane.c | 68 ++++---------- drivers/gpu/drm/exynos/exynos_mixer.c | 6 +- drivers/gpu/drm/i915/intel_display.c | 6 +- drivers/gpu/drm/msm/mdp/mdp5/mdp5_plane.c | 3 +- drivers/gpu/drm/omapdrm/omap_drv.c | 3 +- include/drm/drm_crtc.h | 21 ++++- 12 files changed, 271 insertions(+), 80 deletions(-) -- 1.9.2 -- To unsubscribe from this list: send the line "unsubscribe linux-samsung-soc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
