映射到同一个enable功能上, 这样vop驱动主体调用VOP_WIN_SET(vop, win, enable, 1); 时就能操作到真实的vop寄存器了. 图层接口: static const struct drm_plane_helper_funcs plane_helper_funcs = { // 预先对图层进行处理 .prepare_fb = vop_plane_prepare_fb, // 图层显示完成后的处理 .cleanup_fb =...

我们在文章《Rockchip RK3399 - DRM子系统》和《Rockchip RK3399 - DRM驱动程序》中介绍了RM子系统的整体框架,并对DRM各个模块进行了简单的介绍,本节我们将会详细介绍framebuffer、plane。 回到顶部 一、显示处理器 我们知道一个显示子系统由显示处理器(vop,video output processor)、接口控制器(mipi,lvds,hdmi、...
上图蓝色部分则是对物理硬件的抽象,黄色部分则是对软件的抽象。虚线以上的为drm_mode_object(或者说是modset object),虚线以下为drm_gem_object(或者说是gem objec)。 这些objects之间的关系: 通过上图可以看到,plane是连接framebuffer和crtc的纽带,而encoder则是连接crtc和connector的纽带。与物理buffer直接打交道的...
