Hi, Mark and all. This patch set would add the RGA direct rendering based 2d graphics acceleration module. This patch set is based on git repository below: git://people.freedesktop.org/~airlied/linux drm-next commit id: 568d7c764ae01f3706085ac8f0d8a8ac7e826bd7 And the RGA driver is based on Exynos G2D driver, it only manages the command lists received from user, so user should make the command list to data and registers needed by operation to use. I have prepared an userspace demo application for testing: https://github.com/yakir-Yang/libdrm-rockchip That is a rockchip libdrm library, and I have write a simple test case "rockchip_rga_test" that would test the below RGA features: - solid - copy - rotation - flip - window clip - dithering Thanks, - Yakir Yakir Yang (4): drm: rockchip: add a common subdrv interfaces drm: rockchip: add RGA driver support ARM: dts: rockchip: add RGA device node for RK3288 ARM: dst: rockchip: enable RGA support on veyron devices .../bindings/display/rockchip/rockchip-rga.txt | 36 + arch/arm/boot/dts/rk3288-veyron.dtsi | 4 + arch/arm/boot/dts/rk3288.dtsi | 13 + drivers/gpu/drm/rockchip/Kconfig | 9 + drivers/gpu/drm/rockchip/Makefile | 1 + drivers/gpu/drm/rockchip/rockchip_drm_drv.c | 82 ++ drivers/gpu/drm/rockchip/rockchip_drm_drv.h | 19 + drivers/gpu/drm/rockchip/rockchip_drm_rga.c | 977 +++++++++++++++++++++ drivers/gpu/drm/rockchip/rockchip_drm_rga.h | 108 +++ include/uapi/drm/rockchip_drm.h | 63 ++ 10 files changed, 1312 insertions(+) create mode 100644 Documentation/devicetree/bindings/display/rockchip/rockchip-rga.txt create mode 100644 drivers/gpu/drm/rockchip/rockchip_drm_rga.c create mode 100644 drivers/gpu/drm/rockchip/rockchip_drm_rga.h create mode 100644 include/uapi/drm/rockchip_drm.h -- 1.9.1
