Hi,
Any news on those patches ?
Could we rely on them to upstream z-order fix on sti driver ?

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.
The next part is a result of my survey on introducing generic plane
blending related properties:
http://www.spinics.net/lists/dri-devel/msg98106.html
Ville Syrjälä suggested that blending mode should be defined by a pair
of 2 factors, which define generic blending equation. I've implemented
this approach. I hope that this code can be a base for further discussion
on generic blending support. For more information, see patch 4/5.
Patches are based on top of v4.5-rc1 release.

Changelog:
v5:
- added patch with new generic blending and alpha properties
- changed patchseries topic to "drm/exynos: introduce generic zpos and
blending properties"
- moved all generic code to separate drm_blend.c file
v4: http://www.spinics.net/lists/dri-devel/msg98654.html
- 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 (5):
drm: add generic zpos property
drm/exynos: use generic code for managing zpos plane property
drm: simplify initialization of rotation property
drm: add generic blending related properties
drm/exynos: add support for blending properties
