Unable to capture opencl application on Linux/ROCm

[gggh000]

I used the opencl application xgemm and attempted to capture. However the rgp does not detect it as running and it is not listed in "active applications", because of it, I can not capture trace.
The same rgp version used can capture vulkan application fine i.e. small app named vkcube that ships with the vulkan-sdk, however no success with opencl app.

Can you try this again with the recently-release 1.8 version of RGP?

Let us know if you still encounter problems

it broke even further. Can not even start developServiceCLI:

root@i58400-u1804:/rgp/RadeonDeveloperTools-2020-09-11-26# [DevDriver] [RouterCore] Failed to register transport: \.\pipe\AMD-Developer-Service

Type "q" or "quit" to exit

I can not do a QA job for you, this is not my responsibility. It is your responsibility to test your own code before announcing "try 1.8". it is wasting my time !

Same here. I'm trying to profile an OpenCL kernel in darktable on Ubuntu 22.04.1 with driver version 22.20 and RGP 1.13.1. Application never shows up even though I've switched the workflow to "Compute (OpenCL)" (horrible UX, BTW).

Is there a way to trigger something from the command line? Which component is responsible for the capture?

Hi @Sturmflut : OpenCL on Linux is not supported by RGP. It is only supported on Windows.

On Linux, OpenCL runs on top of ROCm, and that driver stack does not support RGP. The ROCm team provides tools for profiling on that driver stack. I'm not that familiar with the tools there, but I believe rocprof is the tool to use for profiling (https://rocmdocs.amd.com/en/latest/ROCm_Tools/ROCm-Tools.html)

Updated the title of this issue to mention that the request being made here is for Linux/ROCm support. I didn't realize at the time that the original reporter was running on Linux.

There are no immediate plans for such support, as the ROCm driver stack does not currently support generating RGP data.
