Hi all,
I am working on power consumption about android games. I think GPU consumes more power than other units when playing games.
I want to know if Mail Graphics Debugger could provide some information about the load of GPU and what cause this situation…
Hi. I am new to this forum. Sorry for the newbie question..
I'd like to be able to do performance benchmarking across different vendor SoC's. My application runs on QNX. Can you recommend performance analyzers that would work for me? I just found…
Hello.
As for the Streamline tool, I haven't solved the problem in two days.
Please respond quickly.
The situation is as follows :
Version : Arm Streamline Performance Analyzer Version 6.5.1, Build 20180103_121655
Mobile Devices : Galaxy S7, android…
Hello.
Currently, our company is using DS-5 streamline to optimize algorithm running on T764 Mali based device. And we can now only gather the CPU, memory and other debugging information, but can not get to the GPU data. Counter selector which is not related…
Hello, recently I am studying mali gpu counters and encountered some questions about the counter "primitive loaded" and "primitives dropped". I refer to the counter explaination here https://community.arm.com/docs/DOC-10182#jive_c…
Hi,
I am trying to determine whether or not Mali400 GPU get utilized for certain CSS web animation, is there a tool to show how much GPU is being used like the CPU usages display in command like top?
I am using Ubuntu 14.04, is there a tool that can do…
Hello everyone,
I am using DS5 streamline CE to collect GPU information.
In the sw/streamline/gator/README.md, it says :
___To add the corresponding support to Mali___
Userspace (scons) needs gator=1
I am not an expert on scons. What should…
Hi there,
I am using the Community Edition of Streamline and am connecting to an EXYNOS5422 with a ARM Mail-T628 on board. I was able to successfully extract all the counters from the Mali GPU and I'm wondering if there is a way to extract Frame Time from…
When profiling my shaders using Streamline, I found some odd things concerning the usage of GPU cycles (picture below).
The GPU I am testing on is a Mali T-880 (12-core), supposedly running at 650MHz. What surprises me is that within 1s only 442Mcycles…
While profiling I noticed that Streamline differentiates between 128-bit memory access and <128-bit memory access. For example loading a highp 4-vec vs. loading a mediump 4-vec. Is there any difference in latency between a short and a full-memory access…
Hi Peter Harris,
I have the following questions regarding Mali T-628 GPU.
I am running a 3D convolution OpenCL kernel in Mali T-628 GPU (set of 4 cores device). I obtain the GPU cycles counter using Streamline
The GPU Vertex-Tiling-Compute:Activity counter…
I am trying to optimize an app for Mali GPU. I am using a ARM Mali-T830 MP2 based device. I am trying to see which frame/draw is stressing the GPU, but not able to get frame level or draw call level data from the tool. I am getting data from the counters…
I've been profiling a 3D scene on the Samsung Galaxy S7 and I've noticed that glDrawElements and glDrawArrays CPU time is a lot larger compared to Adreno and PowerVR GPUs.
For some context, in an effort to improve performance on Mali devices, I…
I want to calculate the GPU Usage likes busy cycles/ total cycles *100.
But I can´t find any file to extract those information.
I can´t find /sys/devices/platform/mali.0 in my mobile.
Is there any way to get them?

Hello,
I am trying to build kernel for Samsung Galaxy S6 to use DS-5 streamline. In menuconfig, "Mali Midgard series support" and "Mali t6xx r4p0 support" have dependency (They should be configured togehter). It causes compile error that r4p0 has not…
Hi, I try to measure our game's performance on galaxy s6(SM-G920K). I measured on galaxy s7 successfully, but I coundn't do that on s6. I added some log code to gatord source code, and got this message. What should I do??
MaliHwCntrReader::create…Has anyone successfully incorporated Streamline with a rooted Note 5? I'm looking with some trepidation at the instructions for the Note 4 and wondering how transferable they're likely to be...
Hi all:
I used gator and streamline to check the MALI T760MP4 L2 cache hit ratio. But the performance is bad. The read hit ratio is about 64%. Is Mali L2 cache a tile-based cache ? If so, how to optimize the data format for mali L2 cache ?
Thank you
…Hi
It's me again!! I've moved on from compiling via scons, sorting out the libOpenCL stub libs and running the examples. The inacantation shown in the documentation under Building for linux-> How to manually build the examples has some issues that I…
Hello,
I am attempting to use streamline with imx6ul evk. I have build the kernel with gator, and added gatord to my root directory. I have successfully used it before, but now I'm getting "readProcSysDependencies failed". Any idea on what to look for…
Hi,
I'm trying to profile GPU utilization of the Mali T628 on an Odroid-XU4 board using Streamline. When I run some graphics workloads, sometime I can see "GPU Fragment Activity", "GPU Vertex Compute" and "GPU Vertex-Tiling-Compute Activity" adds up…
I follow steps in here http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.dui0482n/ric1362178383724.html
but still, I can't see GPU fragment in streamline data of ds-5, I can see job manager, GPU tiler and MMU related field.
Anyone know why…
hi everyone:
I recently used Streamline to analyze the performance of the cocos2d game, but the data too much, I want to ask, if I want to optimize the performance of the cocos2d game, I need to focus on what metrics?
I now know of are:
1. whether texture…
