[PATCH v5 0/5] drm/exynos: introduce generic zpos and blending properties

2016-02-23 Thread Benjamin Gaignard 
Hi,

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

Regards,
Benjamin

[PATCH v5 0/5] drm/exynos: introduce generic zpos and blending properties

2016-01-27 Thread Marek Szyprowski 
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.

Best regards

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
