Would the patch discussed in that issue https://github.com/llvm/llvm-project/issues/44186 also work in this case ?
Best regards,

1 year ago Hello everyone! I'm a noob using LLVM for anything, and I'd like to use CLBlast with my AMD Renoir APU (R7-4700U GFX 909 GCN 5.1), which requires LLVM to support gfx909. What can we do to get this working?

12 months ago After trying the trick with symlinking the missing .bc file, clinfo is satisfied but CL actually doesn't work.
Even this very simple OpenCV program halts the Renoir GPU:
// cl_error.cpp
#include <opencv2/opencv.hpp>
int main(int argc, char** argv)
{
cv::UMat m(8, 8, CV_8UC3, cv::Scalar::all(0));
return 0;
}(compile with g++ cl_error.cpp -lopencv_core, library from libopencv-core-dev).
What the program does is allocate GPU memory and then run a simple kernel to assign zeros to this memory:
__kernel void set(__global uchar* dstptr, int dststep, int dstoffset,
int rows, int cols, dstST value_)
{
int x = get_global_id(0);
int y0 = get_global_id(1) * rowsPerWI;
if (x < cols)
{
int dst_index = mad24(y0, dststep, mad24(x, (int)sizeof(dstT1) * cn, dstoffset));
for (int y = y0, y1 = min(rows, y0 + rowsPerWI); y < y1; ++y, dst_index += dststep)
storedst(value);
}
}My system runs AMD Ryzen 7 PRO 4750U with only integrated GPU (Vega 7), Ubuntu 18.04, kernel 6.5.3. Mesa 22.3.6 and OpenCL via mesa-opencl-icd.
So I think these newer architectures might actually need something different than the older tahiti compiler. The question is, obviously, what is the missing part.

8 months ago By the way we have now finally an official merge or pull request regarding the missing support of newer AMD GPUs in libclc. Check #78884 for more details.
And it really looks that it will cover even more of those missing AMD GPU symlinks. :smiley:
However, when someone (like @peci1) will test this with newer Mesa and newer LLVM then be aware of the following fact. The new LLVM pass manager which is required since LLVM 17 has some drawbacks with clover. This was reported in the corresponding Mesa MR 24879 clover/llvm: move to modern pass manager.
So until LLVM 16 that Mesa MR 24879 change can be theoretically reverted and clover will then use again the legacy pass manager. But for LLVM 17 and newer this is no longer possible. Note, - the new LLVM pass manager support landed in Mesa 23.3.0 so the previous Mesa 23.2 is the last release which supported the older one.

8 months ago @lorn10 Hmm, I wanted to test, but apparently I don't know enough to do it.
I'm running Ubuntu 20.04 with Mesa 23.3.3 from https://launchpad.net/~kisak/+archive/ubuntu/kisak-mesa/+packages . This normally works, except OpenCL.
So I downloaded the sources for LLVM (current git), SPIRV-LLVM-translator (current git) and mesa 23.3.3 (pristine tar from the above PPA, debian patches not applied).
I've built and installed these into a custom folder (building llvm/libclc, too). But it seems I'm still missing something and a mixture of new and old OpenCL is achieved when I run the example from https://github.com/llvm/llvm-project/issues/52665#issuecomment-1732658768 with LD_LIBRARY_PATH and PATH set to the custom install dir.
When I run the example, I get:
: CommandLine Error: Option 'openmp-ir-builder-optimistic-attributes' registered more than once!
LLVM ERROR: inconsistency in registered CommandLine optionsI tried to comment out the fatal errors for multiply defined attributes in llvm source code. This lets clover continue a bit longer, but segfaults later in pipe_radeonsi PassManager code:
Thread 1 "a.out" received signal SIGSEGV, Segmentation fault.

The host compiler doesn't matter. You should be building mesa/libdrm against the custom built

8 months ago Thanks @peci1 for the testing. :+1:
As far I know we have on older Debian/Ubuntu some strange problems with newer (and especially mixed) LLVM versions. For example, even 22.04 LTS is in the oibaf PPA limited to LLVM 15. According to some comments on Mesa the underlying problem is purely Debian related and not reproducible on other distros.
Therefore I think if 22.04 LTS has those LLVM flaws, 20.04 LTS might be even more critical. :thinking:
So instead of installing the newest LLVM the libclc patch can be used within a LLVM 15 installation. I know that there exist a way to add individual patches to LLVM when it is build.
Whatever, I am on 22.04 and I simply wait until the libclc patch will be included in the oibaf PPA Jammy branch. And yes, this would be possible also regarding the kisak PPA.
Note, - Mesa devel 24.1 needs at least LLVM 15 when OpenCL support is included. This was changed recently because the older LLVM support was already broken.

7 months ago Yeah I have not really a clue about that LLVM stuff. However, I would try to revert anything (LLVM, kisak PPA) to stock and then do an upgrade to 22.04 LTS. This would open the door to use the oibaf PPA.
Perhaps @FabioPedretti has any idea if the libclc patch can be integrated into the LLVM 15 Jammy branch. And most likely an upgrade to 22.04 LTS might generally improve the situation with newer LLVM versions even if Jammy is in the meantime also quite old.

7 months ago I don't plan to try to patch llvm 15. But if a patched version of llvm 15 appears in some Ubuntu version (for example on 24.04/noble), I could try to backport it to 22.04/jammy.

7 months ago Probably it would really make sense to include that libclc update also into any further (not planned) LLVM 17.0.x or LLVM 16.0.x release.
So for the case that there exist somewhere an "informal" LLVM backport fix list, - please include also MR https://github.com/llvm/llvm-project/pull/78884. @arsenm :+1:

7 months ago Can this be closed? There won't be any more 15/16/17 releases

7 months ago The underlying issue is resolved at least for the upcoming LLVM 18 so yes this can be closed.
And for older LLVM versions there exist the possibility to re-build them with that #78884 patch.
(As long as the underlying distro isn't too old.)
Dear all,
My OpenCL tasks within BOINC all fail with the following error message:
The file "gfx909-amdgcn-mesa-mesa3d.bc" is indeed missing from the libclc-amdgcn package in my Linux distribution of choice (Debian 11 "Bullseye"):
https://packages.debian.org/bullseye/libclc-amdgcn
My setup sports an AMD Ryzen 7 4800H CPU with Radeon Graphics (AMD Renoir).
Do you think support for this recent GPU could be added in a future release ?
Best regards,
Samuel
