    Hi,

  • Confusion about the cycles in streamline

    Shawn Chang

    In streamline, multiple counters use cycles,e.g.
     MaliGPUCyclesGPUActive,MaliGPUCyclesNonFragmentQueueActive,MaliGPUCyclesFragmentQueueActive,MaliCoreTextureCyclesTexturingActive
    .

    In my understanding, these cycles describe the time consumption on the time…

    ARM性能分析器(Streamline) 7.0版开始支持基于SPE(统计性能分析扩展)的性能分析。SPE是Armv8.2-A架构中的一个可选扩展特性,它可以以很低的代价对处理器的流水线进行采样。Streamline可以从Arm Development Studio和Arm Mobile Stuido获取。

    为什么需要SPE?

    Streamline前序版本只能通过硬件计数器和软中断中采样PC信息获取CPU的信息。硬件计数器只记录触发事件加总数,不可能知道具体哪条指令触发了事件,它只能大致提供应用程序哪块代码触发了这个计数器增加…
