Introduction Video decode (e.g. YouTube playback) and encode (e.g. video chat applications) are some of the most complex compute operations on the modern web.  Moving these operations from software running on general-purpose CPUs to dedicated hardwar…
Video Playback and Compositor Authors: jamesr@chromium.org, danakj@chromium.org The Chromium compositor has support for video playback to support offloading work to the GPU and displaying video frames while the main thread is blocked.  There are a fe…
GPU Accelerated Compositing in Chrome Tom Wiltzius, Vangelis Kokkevis & the Chrome Graphics team updated May 2014 This code is changing due to Slimming Paint and thus there may be large changes in the future. Note also that some class names may have…

摘要:Part I探析GPUclient之间的同步问题,以及Chromium的GL扩展同步点机制的基本原理.本文将源码的角度剖析同步点(SyncPoint)机制的实现方式. 同步点机制的实现主要涉及到是怎样跨进程实现两个GL扩展接口InsertSyncPointCHROMIUM和WaitSyncPointCHROMIUM,以及GPU服务端的同步点等待. GPUclient GPUclient将全部的GL命令都封装在GLES2Implementation中.GLES2Implementation将…

摘要:Chromium于GPU多个流程架构的同意GPUclient这将是这次访问的同时GPU维修,和GPUclient这之间可能存在数据依赖性.因此必须提供一个同步机制,以确保GPU订购业务.本文讨论了下一个多进程架构GPUclient之间的同步,而同步点(SyncPoint). GPU进程架构等基本概念 我们知道,Chromium是一个多进程架构的软件系统.出于安全和稳定性方面的考虑,Chromium有个专门的进程(或者线程)和GPU设备进行交互,运行GL操作,也就是说,不论什么一条GL命令都…
