Public bug reported:
As part of the coordinated ROCm 7.14 whole-stack transition in stonking,
Ubuntu drops all non-amd64 ROCm builds (AMD's LLVM fork used on Ubuntu from
7.14 is amd64-only). See FFe:
https://bugs.launchpad.net/ubuntu/+source/rocm/+bug/2164631
src:ggml currently produces ROCm/HIP-linked binaries on: arm64.
To let the stale non-amd64 ROCm binaries be removed from stonking without
breaking this package, its optional ROCm/HIP backend needs to be disabled
on those architectures on Ubuntu.
How to disable (Ubuntu-only, gated on derivative.ubuntu):
HIP is a separate binary package (libggml0-backend-hip) already behind a
pkg.ggml.nohip build profile. Restrict the HIP backend to amd64 on Ubuntu
(gated on the auto-activated derivative.ubuntu build profile). Other backends
(blas/vulkan/rpc) are unaffected. Debian keeps building the HIP backend on all
its architectures (it uses upstream LLVM, not AMD's amd64-only fork).
This is a vendor-conditional packaging change; non-ROCm functionality is
retained on the affected architectures (hipfort excepted, being ROCm-only).
All affected packages are in universe and unseeded.
