KMS主要负责显示相关功能,在DRM中将其进行抽象,包括:CRTC、ENCODER、CONNECTOR、PLANE、Framebuffer、VBLANK、property;它们之间的关系如下图所示: 以HDMI接口为例说明,Soc内部一般包含一个Display模块,通过总线连接到HDMI接口上; Display模块对应CRTC; HDMI接口对应Connector; Framebuffer对应的是显存部分; Plane是对Framebu...
drm_modeset_acquire_ctx 是 Direct Rendering Manager (DRM) 子系统中的一个结构体,用于在进行模式设置操作时管理锁的获取和释放。模式设置操作涉及到多个显示资源的配置,如 CRTC(Cathode Ray Tube Controller)、Plane 和 Encoder 等,这些资源通常需要锁来确保一致性和避免竞争条件 更新全局 nv_drm_driver 以支持预...
