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:
v3: - 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
