Hi Jakub,
Jakub Jaszewski, on 2022-11-04:
Please forgive me if this is not the right place to discuss such
issues. My
name is Jakub and for my work I use FOSS 3D software - Blender [1]
for which
recently AMD contributed HIP compute backend [2] as part of the
official
support.
I think you're at a right place to discuss ROCm related topics
in Debian context. :)
After ROCm 5.2.3 landed in Debian unstable I gave it a try with
Blender, and
after some initial hurdles with binaries path I encounterred an LLVM
error
which resulted in a crash. Blender developer said that this is not
something
they can fix. The entire issue is documented on Blender bugtracker
[3] where
you can find all the details.
The most relevant part of debug log:
I1102 11:33:38.655006 91168 device.cpp:32] HIPEW initialization
succeeded
I1102 11:33:38.655035 91168 device.cpp:34] Found precompiled kernels
mesa: CommandLine Error: Option 'h' registered more than once!
LLVM ERROR: inconsistency in registered CommandLine options
Aborted
I don't know if this can qualify as a bug that should be reported
here on
debian bugtracker or somewhere else. Any help would be greatly
appreciated.

I have been scratching my head on what would be the necessary
changes to properly hide symbols so to prevent them from
colliding with Mesa; as far as I could witness, except for the
rocm-smi-lib, library symbols are already filtered. But it is
quite possible I missed the point and didn't look at the right
things (I've been after .map, .def and packages symbols lists).
Other than that, I tried to build a custom blender 3.3.1 version
with HIP Cycles support following the packaging changes
suggested by Cordell Bloor in #1021646[4], to see if I could
reproduce the issue.

Apparently I managed to reproduce a crash about at the same step
as you observe. I got a slightly different output when running
blender through the debugger: the Mesa CommandLine Error does
not appear on my end. Here below is the tracing information
from the debugger:
I1105 00:57:15.862457 879154 device.cpp:32] HIPEW initialization
succeeded
I1105 00:57:15.862509 879154 device.cpp:34] Found precompiled kernels

In hope this helps pinpointing what's wrong,
