Patched for GFX7xx?

[iamhumanipromise]

Hello! rocminfo displays my gfx701 device with the full amdgpu-amd-amdhsa--gfx701 identifier. opencl however begins to show the only the first part of clinfo before freezing.

Is there a way to patch this to force gfx701 support? (In a similar fashion to the arch4edu. llvm-amdgpu package, I suppsose)

It looks like the device libs have bitcode for gfx701.

(Use case: using multiple gfx701 devices in a distcc system to speed up compile times while using new GPUs for other projects with -fopemp offload --- also to play with opencl performance tests)

llvm-amdgpu has been dropped from the arch4edu repository on github.
But I haven't got time to remove it (and other dropped and old packages) from the pacman repository yet.

[iamhumanipromise]

Please keep it, if possible, for older cards, as part of a "legacy bundle"?

[tpkessler]

With our packages we try to follow upstream as close as possible. A legacy version of ROCm (that is pre 2.0) would require a separate repo.

[iamhumanipromise]

Ah that is unfortunate. What is needed for a legacy version to exist? Would like to provide compute resources or testing, maybe even host (Ubiquiti UDM + 400/40mb connection, would cap upload speeds however)

The difficulty in trying to get ROCm pre 2.0 to build is so large than any amount of resources you provided, short of hiring a full time compile/integration engineer, would be insufficient. If you really need this and have the money/resources to spare it is best to just upgrade your hardware.

What was the patch for the llvm-amdgpu package? If it doesn't interfere with support for other gfx's then feel free to submit a PR and we can take a look at it.

I cannot recall that there was a patch for llvm-amdgpu for Hawaii.

[iamhumanipromise]

Apologies, it appears it was an unofficial script "patch" for Fiji/Tonga cards which are GFX8xx cards. Due to the naming nomenclature (R9 285) and co-existance on the marketplace, I mistakenly believed Hawaii to be GCN 3.0 and have been corrected.

Thank you for your continued efforts.

[tpkessler]

I doubt that it is possible to support (pre-) Hawaii cards with current ROCm. Support was dropped before ROCm 2.0, see this comment and the discussion in the linked issue.
