GEM主要负责显示buffer的分配和释放,linux内核中使用struct drm_gem_object表示GEM对象,驱动一般需要用私有信息来扩展GEM对象,因此struct drm_gem_object都是嵌入在驱动自定义的GEM结构体内的。 gem object的创建以及初始化步骤如下: 创建一个GEM对象,驱动为自定义GEM对象申请内存; 通过drm_gem_object_init来初始化嵌...
struct drm_driver是一类DRM设备的驱动程序。 struct drm_framebuffer表示一个提供给CRTC的抽象内存对象。 structdrm_framebuffer {structdrm_device *dev;structlist_head head;structdrm_mode_objectbase;charcomm[TASK_COMM_LEN];conststructdrm_format_info *format;conststructdrm_framebuffer_funcs *funcs;unsigned...
