I am trying to use omniperf to analyze my kernel, but the GUI & ASCII output shows empty tables, for example:
Some tables have some info, which seem wrong (I use v_mfma in my kernel so would not expect 0):
Linux Distribution
Ubuntu 24.04 LTS (Noble Numbat)
ROCm Compute Profiler Version
2.1.0
GPU
AMD MI250
ROCm Version
/opt/rocm-6.2.4/bin/rocprof
Cluster name (if applicable)
xcomx250-1
Reproducer
Build some kernel with hipcc, in my case I use this kernel (this kernel happens to use a single thread block, but I have the same issue for kernels using many thread blocks)
Use omniperf analyze -p workloads/mfma_mine/MI200/ (if the --gui option if you want to)
I am having the same problem with current dev and trying to profile the vgprbound kernel in the occupancy.hip example in this repo.
I am on rocm 6.3.2 and rocprofiler-compute git at 3396ba3
i executed rocprof-compute profile -n occupancy -k vgprbound --kernel-names vgprbound -- sample/occupancy with finishes with no supicous output, but there is no data in any of the fields given by analyze.
This is in fact a bug with rocprofv1 specifically (which seams to get chosen by default) setting ROCPROF=rocprofv2 makes the supported metrics show up.
Understanding what metrics are supported is a bit hard due to --list-metrics being broken see #558 and rocprofv2 seams disabled on gfx908 for seemingly no reason, as it works fine, see #559
