I'm trying to infer if our application is bandwidth-bound (I believe it's not the case) but I don't have the read/write beat counters suggested in Tutorial. Although, I believe the ones I have already "resolve" the beats to the actual bytes…

Hi,
I'm looking at some limited data captured on Streamline (due to the device making only a few counters available - GPU: Mali-T720). When looking at the Mali Shader Cycles, although the large part of the time is spent on TriPipe cycles, there's parts…
In streamline, multiple counters use cycles,e.g.
MaliGPUCyclesGPUActive,MaliGPUCyclesNonFragmentQueueActive,MaliGPUCyclesFragmentQueueActive,MaliCoreTextureCyclesTexturingActive.
In my understanding, these cycles describe the time consumption on the time…
In the streamline counters, what does the "Sample test cull rate" mean in Mali Geometry Culling Rate?
"The percentage of primitives entering the sample coverage test that are killed by it." -- This is tips for this counter. But i can not get…

We see, the non-fragment and fragment workloads are not parellel.
"This expression defines the fragment queue utilization compared against the GPU active cycles. For GPU bound content it is expected that the GPU queues will process work in parallel…
The Development Solutions Group is happy to announce that the latest release of Arm Development Studio is now available. This 2020.1 release showcases the continued improvement in support of the latest Arm IP within our flagship toolchain. A focus for this…
Hello,
We tried running to do a performance comparison of our game with Vulkan integrated in out built and one without it(OpenGL). When we ran the Vulkan built apk and tried to capture some streamline data we seem to not get some data like "Frame Rate…
Although already stated by Pete before in this thread it seems that I'm getting a slightly higher than expected overhead from the lightweight interceptor. The FPS seems to drop by around 3-4FPS and seems more jittery than when playing without Streamline…
Hi.
I wanted to understand the description of some of the Mali-G77 Performance Counters and the metrics we can derive from it. I read the blog by Mr. Peter Harris about the Streamline counters and also the "Mali-G77 Performance Counters Reference"…
Hi.
Wanted to know if we can disable FPK feature in some way? Is it possible if we disable depth information from our applications? Basically I wanted to draw everything that the application sends, even if the objects overlap on each other, but I see…
I installed Arm Development Studio. (https://developer.arm.com/tools-and-software/embedded/arm-development-studio/evaluate)
I set up license using Arm DS IDE, and start streamline,
The free license set in the Arm DS IDE doesn't seem to be activated properly…
Hi,
I believe I'm misinterpreting the counter templates in the Mali Core Unit Utilization on my S10e (Mali-G76), so just need some clarification. My initial assumption was that the counters would add up to 100%. However, as you can see below, they're…
Hi,
For reasons unknown to me, the $FrameRateEGLContext**** (the **** representing the memory address, or equivalent suffix) counter seems to be absent from some of my captures and I'm struggling to understand what could be the reason. During some captures…
Future augmented reality (AR) devices execute workloads that create immersive experiences - a synergy between real and virtual worlds. Just like our current mobile devices, it is not enough to perform just a single task efficiently, so a collection of…
The embedded world in Nuremberg (Germany) is one of the largest fairs dedicated to embedded systems. Arm has a strong presence there and showcases exciting new technology on various demo pods. The following video introduces one of them, a system for augmented…
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…
Is the Starter Editor still a thing?
Im trying to use it with no luck, the error I get is;
"Failed to setup licensing. It looks like licensing file or sewer is not found,...."
I already checked multiply times for my ARMLMD_LICENSE_FILE environment…
Starting with version 7.0, Arm Streamline Performance Analyzer (Streamline) supports profiling using the Statistical Profiling Extension (SPE). SPE is an optional extension to the Armv8.2-A architecture that allows low probe effect hardware sampling of…
Hi,
My understanding is that there are existing processor architectures that are supported in DS5 and Streamline. Then a benchmark application can be selected to run on those existing software models of processors for performance profiling, etc.
My question…
I would like to perform a really fine-grained analysis on a function's performance in Streamline. Specifically, I would like to be able to count how many times an Add operation is performed. In order to do this (effectively), I would need a .csv of the…
Hi, i recently downloaded the newest arm mobile studio start edition. I followed online instructions to set up my environment variables such as ARMLMD_LICENSE_FILE, ARM_TOOL_VARIANT,and by using the gatorme script i can successfully connect my huawei…
Hello there,
I am trying to collect energy data from the STM32MP15 through an energy probe. I configure it on Streamline, I can see the ttyACM0 but no data appears when I launch the capture.
I am using Stramline Community Edition V6.7.1 on Ubuntu 16…
Dear All,
Recently I learn to analyze the performance with gator+streamline, and find that, gator can collect many types of cpu events which are entirely different from those collected by linux perf tool.
Take armv7-cortex-A9 for example, gator can…
Hi,
I want to get the performance of mali gpgpu.And are there some mali gpgpu simulator provided to assist to get it?I want to get the performance by simulator.If you know,please tell me the address.
Thanks
