英特尔“i915”Linux内核显卡驱动程序一直致力于为其显卡启用DisplayPort(DP)的自适应同步SDP提供总结支持。
补丁程序系列将这种自适应同步辅助数据包(SDP)支持描述为:
“自适应同步SDP允许DP协议转换器以最小的缓冲开销转发自适应同步视频。支持自适应同步的DP协议转换器通过设置DPCD寄存器中的相关位来表示其支持。
根据显示配置计算为SDP值,确保在自适应同步环境中正确处理可变刷新率(VRR)。
上周五发出的是V8补丁程序 that refactor the Adaptive Sync SDP code and make various other improvements. This is also the first time the patches were sent to dri-devel, hopefully indicating that the Intel engineers involved are growing comfortable with this feature work and soliciting wider code review.
