[Issue]: rocprofile doesn't work with dlopen hip #140

Closed feniksa closed 1 month ago

feniksa commented 6 months ago

Problem Description

It is unable to trace blender application due to crash

LD_PRELOAD approach doesn't work in case of HIP dynamic load. As result, application will always crash in hipInit call

Blender loads with dlopen hip library see hipew.

In such case, LD_PRELOAD doesn't set traps as expected (see here for additional info).

Operating System

Ubuntu 22.04.4 LTS

CPU

AMD Ryzen Threadripper 3960X 24-Core Processor

GPU

AMD Radeon RX 7900 XT

ROCm Version

ROCm 6.1.0

ROCm Component

HIP

Steps to Reproduce

  1. download blender 4.1.1
  2. unpack anywhere
  3. run blender with profiler: rocprofv2 --hip-activity ./blender

(Optional for Linux users) Output of /opt/rocm/bin/rocminfo --support

Hi @feniksa, I wasn't able to reproduce the crash after following the steps provided. Are you still experiencing this crash with ROCm 6.2.0?

feniksa commented 3 months ago

@harkgill-amd please, let me check. I will update this ticket after re-check. Thanks

taylding-amd commented 1 month ago

I was unable to reproduce the issue with the latest ROCm version, so I will be closing this issue as it appears to be resolved in the newest build. If you have any further questions or need additional assistance, please feel free to reopen the issue or reach out. Thank you!
