Hi
i read the file sys/class/kgsl/kgsl-3d0/gpubusy, and calculate GPUBusy = (first number) / (second number) ,but the GPUBusy always equal 1.0.However，i use Adreno Profiler ，the Metrics %busy is around 40%。i would know how to calculate the Metrics %busy.
Best Regard!

The Adreno Profiler uses a private api with the driver to determine GPUBusy (it's an alternative approach which should give very reliable results)..
However the method with reading sys/class/kgsl/kgsl-3d0/gpubusy should also work. Which device have you run your app on, and are there other devices you can try? Also do you have a version of the app we can verify with as well?
I am also having difficulities with gpubusy. result yields 1.00 even though nothing happens. Would you be so kind to share with us the ardeno profiler formula ? I have snapdragon 800.
Dear,
When I using navigation app, the gpubusy is 100%.
But %shaderbusy that measured by adreno profiler shows around 50%.
How can i guess what kind of GPU block so busy? (It was tested apq8064, and MSM8992 has same)
Thanks
I've been using this quick dirty shell command to get my GPU allocation through GPUbusy, and it works great.
The +1 on the end is to eliminate the divide by zero error when GPU is idle
