[PATCH] drm/stm: ltdc: add layer alpha support

Android Hardware Composer supports alpha values applied to layers. Enabling non-opaque layers for the STM CRTC could help offload GPU resources for screen composition. Signed-off-by: Raphael Gallais-Pou --- drivers/gpu/drm/stm/ltdc.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) diff

[PATCH] drm/stm: ltdc: attach immutable zpos property to planes

Defines plane ordering by hard-coding an immutable Z position from the first plane, used as primary layer, to the next ones as overlay in order of instantiation. This zpos is only an information as it is not possible to modify it, blending operations are still applied from the top to the bottom la

[PATCH 2/2] drm/stm: ltdc: add crtc background color property support

This patch comes from the need to display small resolution pictures with very few DDR usage. In practice, using a background color, produced by the drm CRTC, around this picture allows to fetch less data in memory than setting a full frame picture. And therefore the picture in DDR is smaller than t

[PATCH 1/2] drm: add crtc background color property

Some display controllers can be programmed to present non-black colors for pixels not covered by any plane (or pixels covered by the transparent regions of higher planes). Compositors that want a UI with a solid color background can potentially save memory bandwidth by setting the CRTC background

[PATCH 0/2] Add "BACKGROUND_COLOR" drm property

Hello, This series aims to add a generic background color property for CRTC as discussed in the conversation: https://patchwork.freedesktop.org/patch/439585/ This patch "drm: add crtc background color property" is strongly inspired of Matthew Roper's. Please see: https://patchwork.freedesktop.or
