Hi, This is a first serie to enable the display engine frontend. This hardware block is found in the first generation Display Engine from Allwinner. Its role is to implement more advanced features that the associated backend, even though the backend alone can be used (and was used so far) for basic composition. Among those features, we will find hardware scaling, that is supported in this serie, colorspace conversions, or more exotic formats support such as the one output by the VPU. Let me know what you think, Maxime Maxime Ripard (8): drm/sun4i: backend: Move line stride setup to buffer setup function drm/sun4i: backend: Allow a NULL plane pointer to retrieve the format drm/sun4i: sun4i_layer: Add a custom plane state drm/sun4i: crtc: Add a custom crtc atomic_check drm/sun4i: Add a driver for the display frontend drm/sun4i: sun4i_layer: Wire in the frontend drm/sun4i: sun4i_layer: Add a custom atomic_check for the frontend ARM: dts: sun8i: a33 Enable our display frontend arch/arm/boot/dts/sun8i-a33.dtsi | 1 +- drivers/gpu/drm/sun4i/Makefile | 3 +- drivers/gpu/drm/sun4i/sun4i_backend.c | 139 +++++++++- drivers/gpu/drm/sun4i/sun4i_backend.h | 6 +- drivers/gpu/drm/sun4i/sun4i_crtc.c | 14 +- drivers/gpu/drm/sun4i/sun4i_drv.c | 16 +- drivers/gpu/drm/sun4i/sun4i_drv.h | 1 +- drivers/gpu/drm/sun4i/sun4i_frontend.c | 377 ++++++++++++++++++++++++++- drivers/gpu/drm/sun4i/sun4i_frontend.h | 102 +++++++- drivers/gpu/drm/sun4i/sun4i_layer.c | 75 ++++- drivers/gpu/drm/sun4i/sun4i_layer.h | 11 +- drivers/gpu/drm/sun4i/sunxi_engine.h | 2 +- 12 files changed, 727 insertions(+), 20 deletions(-) create mode 100644 drivers/gpu/drm/sun4i/sun4i_frontend.c create mode 100644 drivers/gpu/drm/sun4i/sun4i_frontend.h base-commit: 4fbd8d194f06c8a3fd2af1ce560ddb31f7ec8323 -- git-series 0.9.1 _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
