Hello,
vProfiler:
- produces *.vpd for OpenGL ES code (e.g. /opt/viv_samples/vdk/cover_flow), but
- does not produce *.vpd for OpenCL code (e.g. /opt/viv_samples/cl11/fft/fft 1024).
How to profile OpenCL with vProfiler (so that the *.vpd file is produced) on i.MX 8M?
If that is not currently possible, what are other options to profile OpenCL on i.MX 8M?
What I do is:
- Use device MCIMX8M-EVK.
- Use software imx-yocto-L4.14.78_1.0.0_ga (Linux).
- Append arguments galcore.powerManagement=0 galcore.showArgs=1 galcore.gpuProfiler=1 to env bootargs in U-boot [1].
- In Linux, set environmental variable VIV_PROFILE to 1 (via export VIV_PROFILE=1) [2].
- Run /opt/viv_samples/cl11/fft/fft 1024 (or any other OpenCL program).
