#257546 — OpenCL with Radeon GPU

FromArno Lehmann <al@its-lehmann.de>
Date2023-04-24 20:10 +0200
SubjectOpenCL with Radeon GPU
Message-ID<Go8Nr-4eYT-3@gated-at.bofh.it>
Hi all,

I'm currently trying to set up a new workstation and wanted to enable 
OpenCL for future use.

GPU hardware is an AMD Radeon RX 6750 XT.

I have a base installation of Debian 12 up and running, kernel 6.1.0.7 
including amdgpu and Mesa 22.3.

Any attempt to actually run any OpenCL program results in an error:

fatal error: cannot open file 
'/usr/lib/clc/gfx1030-amdgcn-mesa-mesa3d.bc': No such file or directory

which is depending on the using program reported more or less easily 
visible. clinfo is sufficient to show this.

Trying to diagnose this with available documentation I learned that
- I am not even able to determine if OpenCL itself should work,
- if it should work with the hardware I have here,
- which versions of amdgpu, xserver, Mesa, llvm or clang I need or which 
particular drivers / packages to install

I have tried several versions of the possible packages, but lacking 
documentation that makes sense to me that was more like blindly poking 
in the dark.

I even tried following some advice to use AMD's out-of-kernel driver 
pack, but the installation script stumbles over dependencies (which may 
or may not be due to the not-yet-stable base distro).

Anyway, the current state is less than satisfying, because I don't even 
understant if OpenCL with Radeon RX 6xxx GPU can even work on Linux.

I would give a different distro a try, but as a mostly-Debian-person I'm 
not really inclined to start learning to maintain more distros. Just 
using Windows would be a solution I would not appreciate at all...

So, my question here: Can anybody confirm this can work in general, or 
even point me to a place for current, correct documentation?

Alternatively, a pointer to where I short report those problems -- 
Debian bug (which package?), freedesktop.org's mesa, Linux kernel 
developers would be appreciated.


Thanks,

Arno

Yes, in general OpenCL for current AMD GPUs works with the open source 
Linux kernel's amdgpu.ko module. On Ubuntu one can install ROCm from 
AMD's repositories

`apt install rocm-opencl-runtime`

which is open source well, but not in standard repositories. Not sure if 
that extends to Debian.

I don't know if this can be substituted in any degree by Mesa.

Debian has: `sudo apt info rocm-device-libs` which provides openCL runtime.

That did not change things, clinfo still causes the
=== CL_PROGRAM_BUILD_LOG ===
fatal error: cannot open file 
'/usr/lib/clc/gfx1030-amdgcn-mesa-mesa3d.bc': No such file or directory

message which seems to indicate that some devie specific stuff is missing.

I'll try to install the Ubunto packages later as this may require some 
serious cleanup first (and sorry for replying to you directly earlier... 
I guess after this days work, hitting the "Reply to List" button was a 
bit beyond my capabilities).

Thanks for your suggestions!

Cheers,

Arno

I don't know anything about this topic, but for such a issue the first 
thing I do is to search inside packages contents from this page:
https://www.debian.org/distrib/packages

In you case, the results might indicate that your GPU is not supported 
by Debian ?
https://packages.debian.org/search?searchon=contents&keywords=mesa3d.bc&mode=path&suite=stable&arch=any

I did that, but there are quite some assumptions implied by this 
approach, mostly that a file of that particular name is *required* for 
nay OpenCL implementation with this hardware -- and that is something I 
hesitated to believe in :-)

Always this same typo of mine   ^
This is either the reason for, or the result of, me not liking Ubuntu ;-)

>> serious cleanup first

Well, I did some of that cleanup (essentially it was removing the 
relevant mesa packages, purging the configuration (removing the entries 
in the /etc/OpenCL/vendors directory) and leaving the one from the AMD 
packages behind.

The results were most exciting:
- clinfo had no error messages any more
- I could start OpenCL Primegrid tasks via boinc

Definitely a step forward.

Unfortunately there are more steps ahead, as any Primegrid task using 
the GPU fails with an error:

opencl error: CL_OUT_OF_HOST_MEMORY

As I have no other real OpenCL workload I can try with any reliability, 
and I also have lots of host memory available, I suspect this due to the 
messy state of the software or its installation. And, as the 
installation has definitely not been done in any documented manner, I 
would not be surprised if that's the problem.

So, the challenge remains to find a way that reliably provides a working 
system, but it seems as though Mesa is not going to be the way towards 
this solution.

Thanks for all your input so far!

Arno

Message-ID<GorZL-4rkf-1@gated-at.bofh.it>
In reply to#257571
Hi all,

a bit of research resulted in me finding this (old) page, which 
indicated there were some environment variables I could use to control 
memory allocation of AMD's OpenCL implementation:

https://community.amd.com/t5/drivers-software/solved-clinfo-reports-error-33-of-quot-global-free-memory-amd/td-p/172760

So I decided to give that a try.

First step: Ensure I can run an OpenCL program from the shell. I used 
the Primegrid binary for that:

# 
/var/lib/boinc-client/projects/www.primegrid.com/genefer22g_linux64_22.12.02 
-h
geneferg version 22.12.2 (linux x64, gcc-7.5.0, boinc-7.20.2)

Command line: '-h'

Running on device 'gfx1031', vendor 'Advanced Micro Devices, Inc.', 
version 'OpenCL 2.0 ', driver '3513.0 (HSA1.1,LC)'.

500000^{2^23} + 1: 116:24:31, 2.64 ms/bit, data size: 192 MB.


So that worked.

It also did not cause an error, but of course, test data != real 
workload, right?

Next step Ensure I can reproduce the error:

#

Command line: '-p -n 22 -b 1053460 -f gproof'

Running on device 'gfx1031', vendor 'Advanced Micro Devices, Inc.',

Interesting, this seems to work without problem. Right now, I'm at

7.29% done, 26:21:57 remaining, 1.22 ms/bit.


which is much longer than what I've seen before.

My conclusion for now: The boinc service must have some limits set.

systemctl show gives me, among others:

LimitCPU=infinity
LimitCPUSoft=infinity
LimitFSIZE=infinity
LimitFSIZESoft=infinity
LimitDATA=infinity
LimitDATASoft=infinity
LimitSTACK=infinity
LimitSTACKSoft=8388608
LimitCORE=infinity
LimitCORESoft=0
LimitRSS=infinity
LimitRSSSoft=infinity
LimitNOFILE=524288
LimitNOFILESoft=1024
LimitAS=infinity
LimitASSoft=infinity
LimitNPROC=253399
LimitNPROCSoft=253399
LimitMEMLOCK=8388608
LimitMEMLOCKSoft=8388608
LimitLOCKS=infinity
LimitLOCKSSoft=infinity
LimitSIGPENDING=253399
LimitSIGPENDINGSoft=253399
LimitMSGQUEUE=819200
LimitMSGQUEUESoft=819200
LimitNICE=0
LimitNICESoft=0
LimitRTPRIO=0
LimitRTPRIOSoft=0
LimitRTTIME=infinity
LimitRTTIMESoft=infinity


My first candidate would be LimitMEMLOCK as I suspect that, for 
interaction between GPU and CPU, shared and locked would be a likely 
way. (You notice I know nearly nothing of OpenCL...)


I do know how 'systemctl edit' works, though, and set the limit to 1 GB:

LimitMEMLOCK=1073741824
LimitMEMLOCKSoft=1073741824

Which did not help, same error after similar time.

Still, seeing that I can run the binary in question from the shell, I'm 
kind of confident this should be solvable via proper unit configuration.


Which leaves me with one question for this mail thread: Can anybody 
recommend a test program for OpenCL functionality?


Thanks,

Arno

There are tests from Khronos:
https://github.com/KhronosGroup/OpenCL-CTS

It's seems to be over 50 tests and then subtests. There are presets to 
run different test suites from a Python script.

I ran only some random ones with ROCm and Mesa OpenCL, using Vega64 or 
RX 5700 XT.

All tested fine with ROCm OpenCL. Mesa OpenCL failed some with Vega64 
and then most tests with the RX 5700 XT...

This is Debian 12.

Hi,

which mesa packages do you have installed?
In Debian testing I see the package `mesa-opencl-icd`.
I have no experience with opencl and AMD graphic cards but are very interested 
how it works in Debian.

Regards,
Jörg.

None providing OpenCL capabilities at that time, but if you followed

That's more or less where I am myself... seems a bit too complex for me, 
at this time ;-)

As I trust the documentation in general, I am kind of confident that the 
problems I see derive from my usage of a too recent GPU; the older 
Radeon Architectures probably works out of the box.

The wiki page https://wiki.debian.org/AtiHowTo would deserve a bit of an 
overhaul, I think, seeing that it does not mention OpenCL at all, for 
example. If I just knew what to put there, I'd be happy to suggest 
something...

Best results so far are with the AMD vendor drivers which are *not* 
intended to be used on Debian:

I'm wondering if package mesa-opencl-icd would do the trick (version 
22.3.6-1+deb12u1 like the other installed mesa packages). From the description 
it seems to be the right package:

free implementation of the OpenCL API -- ICD runtime
  This package contains the mesa implementation of the OpenCL (Open Compute 
Language) library, which is intended for use with an ICD loader. OpenCL provides 
a standardized interface for computational analysis on graphical processing units.

Regards,
Jörg.

That's the package I tried initially which failed all my (limited) 
testing due to the hardware not being supported.

Mesa 23 is available as experimental, but I did not manage to install 
that due to dependencies.

In the end, you'll have to test with your particular hardware, I think 
-- I've not been able to find a reliable and realistic list of working 
hard- and software combinations.



Current state, by the way, is that I'm fighting with boinc and systemd 
in this environment. OpenCL reminds me of the (good|bad) days of 
building my own kernel based upon incomplete information ;-)

Would be fun if I could sink a few days in it.

Cheers,

Arno

As I previously said, I know nothing about the subject so I might be out 
of topic, but:
- in February 2022 someone wrote an interesting article, in French, of 
the current (bad) state of OpenCL Linux software with AMD hardware
- this article points to some English documentation and scripts this 
person maintain [2]

Hope this helps.
